CS252126B1 - Coating composition with high humidity resistance - Google Patents

Abstract

High durability paint and constant quality of action against the negative external influences in the form of an aqueous solution containing 10 to 15% dry matter of acetate, 6-12% of a preservative composition containing mineral oils and alkali salts and alkyl sulfates acids, further pigment white and calcium carbonates, optionally dyes and disinfectants or flavoring agents.

Description

The invention relates to coating wicks and high moisture resistance for the protection of all kinds of building structures, for application to all types of concrete, wood and other porcelains. Materials which have been subjected to weathering, the essential part of which is polyvinyl nylon and oil.

The paint wicks hitherto used create a thin protective film on the surface of the building construction, which prevents moisture from penetrating into the non-material. However, these wicks cannot be applied to a damp substrate, as the moisture of the substrate will cause cracking and peeling of paints from the surface. It does not protect the building structure against hayweed or atmospheric moisture. Due to these effects, the life of the coatings is significantly reduced.

Accordingly, there has been a need to provide a type of paint that removes these drawbacks of etching paints with ease of handling and provides a more complete and durable effect with the novel composition. Due to the wide use of paints for building constructions and their high consumption, low production and operating costs of the newly created paint are required.

This requirement is solved by a coating with a high resistance to moisture. SUMMARY OF THE INVENTION is that the composition consists of 10 to 15% polyvinyl acetate dry matter, 8 to 15% white, 8 to 15% calcium carbonate, 6 to 12% preservative composition containing mineral oil with 0.05 to 0.1% alkali salts of alkyl sulfuric acids having from 10 to 18 carbon atoms in alkyl, the remainder being water. Further, the composition may contain 0.1 to 2% water-dilutable colorant and 0.1 to 2% disinfectant or flavoring.

The coating composition of the disclosed composition exhibits a number of advantages over the prior art coating compositions. It can be applied to a damp substrate. It forms a protective layer on the surface of masonry, concrete and other types of porous aetherals of building constructions, but at the same time it penetrates pores to a depth of up to 0.02 n and permanently prevents moisture from penetrating into the structure. It protrudes the surface of building structures n and does not peel off the surface. Its effects prevent the formation of mold. The paint is very slowly polluted compared to the existing materials, it is washable. The material can be applied by painting and spraying guns of conventional construction.

He did

A coating containing 15% dry matter of polyvinyl acetate, 15% of white (titanium and atrium), 15% of calcium carbonates (ground limestone and chalk), 10% of a preservative mixture containing mineral oil, 0.1% of alkaline alkylsulphuric acid salts of 10 al 18 carbon atoms in the alkyl and the remainder being water. This paint was not sprayed onto the interior surface of the kitchen tract of the restaurant, which is located on the ground floor of the building, not insulated against ground moisture. After 2.5 years, this surface was found to have a very slight contamination of the masonry surface, which was removed by washing with an aqueous detergent solution. Otherwise, no signs of damage were found.

Attached id 2

Ryla created by coating containing 13% polyvinyl acetate dry matter,> 4% white (titanium n-zinc), 8% calcium carbonates (ground limestone and chalk), 8% mineral oil preservative mixture, 0.08% alkaline alkylsulphuric acid salts of 10 18 carbon atoms in the alkyl, 0.5 Ϊ water-dilutable dye and the remainder was water. This coating was applied by spraying on the outside of the plaster of an object not insulated against ground moisture, which is located in a place heavily contaminated with prenyl pollutants. After 2 years, this coating only showed very slight contamination. Otherwise, it showed no signs of damage or color instability.

Example 3

E (a coating composition comprising 15% polyvinyl acetate dry matter, 15% white (titanium and liner), 13 X calcium carbonates (ground limestone and chalk), 12 X preservative and containing mineral oil, 0.05 X alkaline alkylsulfuric acid salts and 10 to 18 carbon atoms in alkyl, 2 x disinfectant and the rest was water The paint was applied to the inner wall of the cowshed by a paintbrush and after 2 years this paint showed only a slight contamination that was removed with an aqueous detergent solution. masonry surface, except for mechanical damage from stabled animals, signs of mold damage or infestation.

Claims (2)
