The results of application of nanotechnology in construction and building materials.

Vadim V. Maltsev, Doctor of Science,

Academy of Natural Sciences, the chief ecologist wooden housing,


scientific and technical director.


This report presents data on the effective application of nanotechnology and nano
-
objects in the
field of building materials and construction, during the past 10
-
12 years.

In his work, we used three types of nano
-
objects:

N

ders with particle size after nano grinding

from 100 to 500 nm;


Aqueous dispersions of copolymers modified special additives (flame retardants, preservatives,
antifreeze, etc.), with the size of the dispersed particles of 60 to 300 nm;


Modifying chemical

The greatest effect of increasing the fire resistance of polymer materials is achieved by the joint
application of "ALGID" li
quid and solid phosphorus and phosphorus

chlorinated plasticizers and some
types of chlorinated compounds.

For example, the use of "ALGID

33. A similar value of the oxygen index was obtained by creating slow
-
burning PVC
linoleum for the railway, which included "
ALGID" is used in conjunction with liquid
-

solid and
phosphorus flame retardants, plasticizers.


It is particularly important to note that in these compositions and materials "ALGID" used instead
of toxic, deficient for Russian consumers and costly antimo
ny trioxide. Thus, th
e industrial application
"ALGID
" in the production of flame

and other mineral chemicals showed that serious
difficulties arise from dusting nano grinding objects. Similar difficulties arise in practical use nano
grinding powders in industrial processes. Since we are always interested in not only experimental, poli
cy
decision, but also a real practical way in technology, have been studied the possibility of "wet" and "dry

"BORANS" is a white powdery product, odorless, low toxicity, Hazard Class 4.

The main purpose of "Borans
"
-

protection of w
ood against the formation of mold during storage and
transport. For antifungal activity "Borans" refers to miko static drugs, ie does not allow for the
development of fungal colonies on wood. Before processing the wood "Borans" dissolved in warm
water at a

ratio of water / "Borans" = 9:1. The greatest effect is achieved antiseptic timber when the
material is tre
ated with a solution of "Borans
" immediately after production by dipping or spraying.

If
antiseptic solution "Borans
" materials not directly subject
ed to rain, the a
ntiseptic action of the
"Borans
" are stored indefinitely, as "Borans" is not volatilized and does not evaporate.

Impregnation of the

surface layer of wood "Borans
" does not prevent subsequent drying and machining
of wood and does not affec
t the appearance and color of natural wood.

Borans comes in polypropylene bags with polyethylene liner weighing 20 kg.

"Borans" was also successfully applied for antifungal protection polymer roofing materials, pipe vinyl

The essence of the "DISPERLEY"
("blanket" or "planar" technology protection of concrete) is to use the
body of the concrete floor to create on the surface of the waterproofing layer with very high mechanical
strength and frost resistance instead of traditional roofing materials.

It uses

latex impermeable copolymer with nanosized particles smaller than the diameter of the pores in
the concrete. Moreover, in giving this dispersion certain supplements can achieve deep penetration into
the pores of the variance concrete slab roof slabs and h

to close the pores in the concrete and ensure
a tig
ht coupling of the surface finish of the concrete. After closing time this structure forms on the surface
of concrete is quite a strong frost hardy film.

And then this polymer layer is covered twice topcoat
-

frost resistant, weather resistant, antiseptic
DOKAS latex paint that provides a complete prevention of the entry of moisture into the body of the
concrete.


The result is a hydrophobic and waterproof layer. You do not need any roofing material.
Moreover, processing yield all the bumps and curves of th
e roof. Where there are joints between the
panels of roof slab
-

their pre
-
sealed. Sealant is a sufficient number, including domestic
-

frost resistance
and durability.


Roof waterproof material is impregnated and finished the top layer of concrete, and th
e total
weight (dry) of polymer components is 210g/m2 roof.

Polymer layer not only makes concrete waterproof, but also strengthens it. And nothing bad will happen,
even if it hit him with a crowbar, because pores of the concrete soaked copolymer. The pores

are closed,
scrap not penetrate into the pores, the place warm hairdryer cleaved and processed primer composition,
and then the finish paint.


Every 7 years, updated paint DOKAS in one layer, and it still is.

And waterproofing coating that forms on the ou
tside of w / w floors, by weight (of which has already
hardened in the pores of the concrete, and formed on the surface) is about 210 g/m2, which is very small
compared to any conventional roofing today, the which the weight starts from 2.5 kg/m2, ie diffe
rent
order of magnitude, at least.

wood floors with toxic organic solvents to water paints. Using a modified mixture of aqueous copolymer
dispersions with particle sizes of 60 nm and 300 nm in size, including the dispersion of nonflammable
polymer, able to create and to produce la
cquer "Ledor" zero emissions, nonflammable and resistant to
abrasion. It is appropriate here to note another important feature of varnish for wood floors on the basis of
water nanodispersions copolymers. In contrast, paints and solvents, water nanodisperse
d paints primarily
filled pores of the wood, and then to form a surface layer of lacquer. With this in grinding surface
clearcoat dirt is not absorbed into the pores of the wood, but remains on the surface. Before proceeding to
update the lacquer layer woo
den floors do not need to scrape (!), But rather flush grated part of the floor
to dr
y and apply nov nanodispersion

varnish. Trade name developed varnish "Ledor."

50 is used in a pure
idea, and as a part of various compositions (Vupreks
, Vuprin, Ledor and others). Dilute
aqueous solutions Diafosa

T

he effectiveness of the flame retardants uncertainty persists long after the treatment
of the material

In the operation of the treated material Diafos

50 does not emit any harmful
substances.


After impregnation m

crystals with high mechanical strength and very soluble in water. While
studies have shown unus
ual fact: dilution Diafosa
-
P
-
50 with water, first leads to
increased efficiency of its action as a flame retardant, despite a decline in the quantity per
unit volume or surface of matter (for example, set fire retardant treatment Ecowool).
Thus, dilution D
iafosa

P
-
50 with water to 1/1 led to increased flame retardant effect and
dilution ½ gave the same effect as a concentrated source Diafos

"CHEPLAR"

Roofing materials for pitched roofs


One of the most pressing problems of our time
-

the use of waste and non
-
recoverable tires. For its solution was able to develop a production recipe unique
material, which uses waste tires (rubber powder) and waste polyethylene (film canister,
flake, etc
.), and the introduction of the flame retardant composition
-

made it flammable.
This material is called
-

"CHEPLAR" from the words "plastic
-
rubber shingles."

Material "CHEPLAR" borrows resistance tires to atmospheric and climatic
influences, which is due
to the following factors:

• Soot, the automotive tire is a powerful absorber of ultraviolet radiation,
providing resistance to sunlight.

• Elasticity of vulcanized rubber allows it to transfer good temperature
fluctuations.

• The presence of antioxidants p
revents aging under oxygen.

When you create a composition in the manufacture of "" were used following the
nano
-
components:

1. Mineral flame retardant "ALGID" (100 nm);

2. Plasticizer
-
retardant "ANNAFOS
-
3" (9 nm);

3. Retardant polymer (9
-
11 nm).

Through th
e use of a 3
-
retardant above the world's first managed to get out of
impermeable material composition, which is the basis of flour mixture with a rubber
from used tires and recycled polyethylene: the material to spread the flames and by the
action of an op
en flame does not form drops, and when setting out from flame
immediately dies (time independent burning is 0 sec.)

Was not a simple solution to exterior color of the material. Getting outside of the
color on the surface of the material with poor adhesion
to all types of dyes used
previously, it was a very strong chemical
-
technical solution. The fact is that, if not only
vary the composition of paint, but also the substrate on which it is applied, the results can
surpass all expectations. Thus, the binding
component was introduced and in the paint,
and one of the liquid flame retardants are added to the composition "ChEPLARa." In
this way, the common component was a "chemical welding" of the layer surface of the
material and a layer of paint. Ie incredible h
appened: it was possible to use a water
-
dispersion paints for coloring rubber surface, and with a plastic filler.

Paint itself deserves special attention. To manufacture it the nano particulate
mineral flame retardant "ALGID" and polymer nanoplasticizers.
In the paint, called
-

"DOKAS" used nano
-
powdered mineral pigments domestic production, as well as a
film
-
forming polymer matrix was used aqueous dispersion of acrylic copolymer
produced in Russia. With competitive test paint "DOKAS" (example of color slat
e) won
by a large margin, two international competition, which was attended by leading French,
German, American, Belgian and Danish companies. Therefore, if the material
"CHEPLAR" occasional touch up paint "DOKAS", it will be eternal material.


Main
applications of the material "CHEPLAR":

1. As a roofing material for pitched roofs.

Material "CHEPLAR" has high mechanical strength and very durable. In
addition, it is very light material (4 times lighter than slate, 10 times lighter than natural
tile). O
n application requirements "CHEPLAR" superior to any variants of metal: not
corroded in places breakdown anchors fasteners, does not proceed in these areas, the
elastic restoring form, does not allow the heat shrink does not screen electromagnetic
fields.
Rot, produces no noise from rain, hail and wind. "CHEPLAR" is able to form
elastic recovery after removal of the snow load. The projected life of the material of 25
-
30 years.

2. As an outdoor and road surfaces.

"CHEPLAR"
-

the material is not slippery. The
refore, the possible use of this
material
-

for sports facilities, flooring for livestock farms, etc., ie where you want to
create not slippery surface.

Technical Description.

"CHEPLAR" is a body
-
shaped "under the tile" roof plate for forming roofing for
s
loping roofs. "CHEPLAR" is formed from high
-
strength, elasticity, cold
-
resistant and
water
-
resistant synthetic sheet material on special presses. Apply a variety of weather
resistant inorganic pigments in the paint "DOKAS" used in the dyeing, allows a wide

range of colors sheets "ChEPLAR." The introduction of "ChEPLAR
" additives, special
flame retardants, can classify it as a non
-
flammability, from the angle of fire.
"CHEPLAR" comes ridge elements podkonkovymi elements corners from the same
source sheet.
