Problems solved by technology

It is strongly alkaline, it is easy to burn your hands when using it, it is harmful to people, and it is unhealthy and environmentally friendly.
[0003] For example, the Chinese patent "CN101838492A" discloses "an acrylic latex powder interior wall paint", 70-100% of water, 10-20% of calcined kaolin, 10-20% of titanium dioxide, 10-20% of talcum powder, and 30-30% of heavy calcium 50%, wollastonite powder 1-15%, lime calcium 5-10%, acrylic acid redispersible latex powder 7-10%, thickener 0.3-0.6%, sodium hexametaphosphate 1-2%, the amount of raw materials is large , the processing cost is high, and it has the disadvantage of time-consuming and labor-intensive production

Abstract

The invention relates to rubber powder. The existing rubber powder has strong alkalinity and has the defects that hands are likely to burn when the existing rubber powder is used, and the existing rubber powder is harmful to people, is unhealthy and unfriendly to the environment, consumes a great number of raw materials, is high in processing cost and wastes time and labor when in production. The rubber powder which is less in consumption of raw materials, capable of saving energy and protecting the environment, easy to operate, simple in processing method, low in cost, easy to dissolve, good in construction performance and free from dropping is prepared by adopting HPMC, polyethylene powder, thickening agent and starch ether as raw materials.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a rubber powder. Background technique [0002] The existing rubber powder is white, light yellow to yellow or amber in appearance, translucent, has no unpleasant smell, and has no visible impurities. For example, "a special rubber powder for water-soluble architectural coatings" disclosed in the Chinese patent "CN1051789C". It is made of quicklime powder, sodium carbonate, flour (starch) and additives in a certain proportion mixed into a uniform powder material. It is strongly alkaline, it is easy to burn hands when used, it is harmful to people, and it is unhealthy and environmentally friendly. [0003] For example, "an acrylic latex powder interior wall paint" disclosed in Chinese patent "CN101838492A", water 70-100%, calcined kaolin 10-20%, titanium dioxide 10-20%, talc 10-20%, heavy calcium 30- 50%, wollastonite powder 1-15%, gray calcium 5-10%, acrylic redispersible latex powde...
