Building adhesive

Abstract

The invention discloses a building adhesive. The building adhesive is prepared from cassava starch of 40 to 50kg, polyvinyl alcohol of 5 to 10kg, cellulose and derivatives thereof of 15 to 20kg, re-dispersible latex powder of 1 to 5kg and a thickener of 0.5 to 2.0kg. The thickener is polyacrylamide. The building adhesive provided by the invention has the advantages of high viscosity, good crack resistance, acid and alkali resistance, good environment protection performance, good mildew-proof and antibacterial performance, simple manufacturing process, low production cost and wide application range, and does not contain any material harmful to a human body, such as benzene, formaldehyde and the like.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an adhesive for building. Background technique [0002] With the development of the economy, the environmental pollution of waste and old expanded polystyrene has been paid more and more attention by people. At present, there are many domestic reports on the production of adhesives with waste and old expanded polystyrene as the main raw material. However, due to the Styrene is glassy, ​​brittle, breaks when touched, has low heat resistance, and its operating temperature is only 60-75°C. Therefore, the existing construction adhesives prepared with waste expanded polystyrene as the main raw material all have bonding strength. Low-level disadvantages, narrow application range, difficult to bond marble tiles, and not suitable for use in occasions with high waterproof and moisture-proof requirements. Contents of the invention [0003] The purpose of the present invention is to pro...
