Cement-based floor polymer waterproof coating, preparation method and equipment

Abstract

The invention discloses a cement-based floor polymer waterproof coating which is prepared from the following components in parts by weight: 68 to 73 parts of a water-based acrylic emulsion, 1 to 2 parts of ethyl naphthol, 2 to 3 parts of di-tetradecyl alcohol ester, 0.1 to 0.2 part of lithium chromate, 2 to 3 parts of a polyether glycol, 0.6 to 1 part of polyacrylamide, 0.6-1 part of 2,6-Di-tert-butyl-4-methylphenol, 2-3 parts of oxidized polyethylene wax; 1 to 2 parts of potassium dodecyl benzene sulfonate; 0.6-1 part of N-methyl pyrrolidone, 0.3-0.5 part of ricinoleic acid, 6-8.5 parts of expanded perlite, 6-7 parts of sericite powder, 6-8 parts of a coalescing agent, 10-16 parts of deionized water, 1-3 parts of rosin modified phenolic resin, 2-3 parts of an anti-settling agent, 1.1 parts of a leveling agent and 0.85 part of an antifoaming agent. According to the invention, the surface film-forming effect of the finished product waterproof coating is improved during use, so that thesurface of the finished product waterproof coating is smooth, flat and uniform after film formation, the elastic adhesion capability of the formed film is improved, the ductility is excellent, and sealed coating film has high tensile strength and elongation at break, excellent waterproof performance, strong acid and alkali resistance and mildew resistance.

Description

technical field [0001] The invention relates to the technical field of waterproof paint manufacturing, in particular to a cement-based floor polymer waterproof paint, a preparation method and equipment. Background technique [0002] The waterproof coatings on the market are roughly divided into two categories: 1. Polyurethane waterproof coatings: This type of material is made of polyurethane and coal tar as raw materials. The volatilized tar gas is highly toxic and not easy to remove, so it was banned in China in 2000. The polyurethane waterproof coating that is still on sale uses asphalt instead of coal tar as a raw material. However, when using this kind of coating, it will be diluted with organic solvents such as toluene and xylene, so it is also toxic; 2. Polymer cement-based waterproof coating: an emulsion synthesized by a variety of water-based polymers and mixed with various additives Composed of high-quality cement, the flexibility of the polymer (resin) and the ri...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventors have found that the following problems still exist in the above-mentioned prior art and have not been solved: 1. When the finished waterproof coating obtained by the comparison patent technical solution is dried and formed into a film, its surface is rough enough and the surface elastic tension effect is not enough 2. In the preparation process of the patented technical solution, it is impossible to artificially and accurately control the heating temperature required for stirring, resulting in the poor effect of the finished waterproof coating in practical application, and even the phenomenon of defective products, which increases the user's burden.
