Wear-resistant anti-freezing coating

Abstract

The invention discloses wear-resistant anti-freezing coating, which is prepared from the following raw materials in parts by weight: 40 to 50 parts of core-shell acrylate emulsion, 10 to 30 parts of modified starch, 20 to 40 parts of polyvinyl alcohol emulsion, 10 to 20 parts of titanium dioxide, 0.2 to 0.4 part of ammonium persulfate, 0.2 to 0.5 part of sodium bicarbonate, 2 to 7 parts of rubberlith, 0.2 to 0.5 part of sodium hexametaphosphate, 0.2 to 0.45 part of sodium fluoride, 0.2 to 0.5 part of tributyl phosphate, 0.5 to 2 parts of dispersing agents, 0.05 to 0.1 part of wetting agents, 0.1 to 0.2 part of anti-foaming agents, 50 to 75 parts of water, 10 to 15 parts of light calcium carbonate, 10 to 15 parts of talcum powder, 10 to 20 parts of precipitated barium sulphate and 1 to 5 parts of bentonite. The coating prepared by the invention has good characteristics of nontoxicity, no pollution and cold resistance; the anti-freezing performance is good; after the freeze-thaw circulation tests and weather resistant tests, bubbling, cracking, pulverization, falling and color change phenomena are not discovered on the surface of a coating film; the washing and brushing resistance, high durability, scribbling prevention, and stain-proof and dustproof effects are realized; precipitation cannot occur after the placement for one year; the condensing is avoided; the comprehensive characteristics are strong; great popularization values are realized.

Description

technical field [0001] The invention relates to a paint, in particular to a wear-resistant and antifreeze paint. Background technique [0002] Coatings used for exterior walls of buildings in alpine regions need to have low temperature resistance. However, ordinary low-temperature-resistant coatings are not suitable for high-cold regions in my country, such as the northern part of Northeast China and the southeastern part of Tibet. Therefore, local standards have been established in various regions. Can withstand certain freeze-thaw cycles. However, even products that comply with such local regulations are not completely suitable for high-latitude areas where the winter temperature reaches -40°C. Therefore, the construction industry has been looking forward to exterior wall coatings with better low temperature resistance, such as being able to withstand 40 times of freezing at -40°C. Low temperature resistant coating for melt cycle. Chinese Patent Publication No.: "CN10395...
