Description

The invention relates to the field of construction, for anticorrosion and waterproofing protection of wooden building structures, in particular mineral fertilizer stores.

Known protective composition for wooden building structures based on glue of polyvinyl acetate and isocyanate crosslinking agent (RF Patent No. 2349447, VL 1/00, publ. March 20, 2009).

However, a disadvantage of the known composition is its low technology.

The closest in technical essence and the achieved result is a protective composition for wooden building structures. comprising a polymer binder and filler (Application for the invention of the Russian Federation No. 2011116536, C09D 5/18, publ. 10.11.2012).

The disadvantage of this protective composition is the low reliability and durability of wooden building structures due to the low protective properties of the components.

The technical problem to which the invention is directed is to increase the reliability and durability of wooden building structures.

This task is achieved by the fact that in the protective composition for wooden building structures, including a polymer binder and a filler, according to the invention, ethinol 1 wt.h. and latex divinyl styrene SKS-65 - 0.15-0.2 mass parts, and as filler - powdered graphite silver foundry - 0.1-0.15 mass parts In addition, in the protection of the composition as an adhesive component using an increased content of latex SKS-65 in the amount of 0.45-0.5 parts by weight

Use as a polymer binder varnish ethinol 1 wt.h. and latex divinyl styrene SKS-65 - 0.15-0.2 mass parts, and as a filler of powdered graphite silver foundry 0.1-0.15 mass parts allows you to improve manufacturability, reliability and durability of wooden building structures due to their chemical properties.

Use as an adhesive component of a high content of latex SKS-65 in an amount of 0.45-0.5 parts by weight provides adhesion of the composition to a wooden surface due to the penetrating ability of the component.

A protective composition for wooden building structures is made as follows.

An example of obtaining a protective composition for the protection of wooden building structures.

For the manufacture of a protective composition for wooden building structures using the above materials, ethinole enamels are prepared on the basis of ethanol varnish.

An approximate composition of the composition based on varnish ethinol:

1. Waterproofing and anti-corrosion top layer:

- ethinol varnish - 1 parts by weight;

- powdered graphite foundry silver - 0.1-0.15 mass parts;

- latex SKS-65 - 0.15-0.2 mass parts 2.

Adhesive:

- ethinol varnish - 1 parts by weight

- powdered graphite foundry silver - 0.1-0.15 mass parts;

- latex SKS-65 in the amount of 0.45-0.5 parts by weight

To obtain compositions in a serial mixer pre-fill varnish ethinol, according to the mass content. Then add filler in the form of powdered graphite silver foundry and mixed to obtain a homogeneous mass. Lastly, latex is added and mixing is completed.

Application of the composition can be done manually (by brush, roller) or by means of small-scale mechanization (in particular, using a pneumatic spraying unit).

The joined parts of wooden structures are pre-impregnated with a clear varnish ethinol, which has a high impregnating ability. Then apply an adhesive composition and connect the parts.

The upper waterproofing and anti-corrosion layer is applied using one of the methods mentioned above.

The polymerization of the adhesive and waterproofing layers occurs naturally at ambient temperature, including negative (up to -40 ° C).

Thus, the reliability and durability of building wooden structures are increased, since the proposed composition has high impregnating and anti-corrosion protective properties, allowing year-round work to protect wooden structures.
