Problems solved by technology

[0004] However, the solid rubber powder currently on the market has serious quality problems, such as poor adhesion, easy powder removal, no water resistance, no resistance to scrubbing, and cannot be used alone in construction. It can be used only after adding white latex, etc.
As a result, problems such as increased cost, inconvenient operation, and poor engineering quality are caused, which are very unpopular with users.

Abstract

The invention relates to a rubber power for building. The rubber power comprises the following components according to the weight by parts: 20-30 parts of etherified starches, 25-35 parts of fiber, 30-40 parts of PVA, 45-70 parts of oxidized starch, 5-10 parts of plasticizer, 8-15 parts of tackifier, 0.5-2.5 parts of antiseptic, and 1-3 parts of water proofing agent. The rubber power for buildingis white and powered in appearance, is innoxious and tasteless, does not have hazardous substance, is convenient to transport, has the advantages of good quality, high viscocity, strong adhesive attraction, non-coming off power, no crack, washing resistance, high strength, fast solution, wide utilization area; and the preparation method is simple and has low cost.

Description

technical field [0001] The invention relates to a rubber powder, in particular to a solid rubber powder for construction. Background technique [0002] 801 glue is made by polycondensation reaction of polyvinyl alcohol and formaldehyde in acidic medium, and then amination. The preparation process contains unreacted formaldehyde. 801 glue production raw materials are: polyvinyl alcohol, water, formaldehyde, urea, hydrochloric acid and sodium hydroxide. 801 glue is often used in home decoration for pasting wall coverings, wallpapers, ceramic tiles and cement products, and can also be used as a glue for interior and exterior walls and floor coatings. 801 glue contains unreacted formaldehyde, and formaldehyde is the root cause of indoor environmental pollution. Moreover, 801 glue needs to add toxic substances such as hydrochloric acid, liquid caustic soda, and formaldehyde during the heating process, which not only consumes a lot of energy and resources, but also causes the g...
