Abstract

The invention relates to a process of preparing adhesive for building materials, characterized in that the adhesive is prepared from ethane-vinyl acetate copolymerized resin, polyvinyl alcohol solution, ethanol or ethylene alcohol, water, lime stone powder, tricresyl phosphate through charging water into lime stone powder, agitating till moistening, charging aqueous solution of polyvinyl alcohol and VAE copolymerized emulsion, finally charging ethanol, tricresyl phosphate, fully mixing the constituents and grinding.

Description

Technical field: [0001] The invention belongs to the technical field of building materials, and in particular relates to an adhesive specially used for bonding wall tiles or floor paving materials to cement surfaces. Background technique: [0002] At present, the construction industry still uses traditional techniques for pasting ceramic tiles, marble, glass bricks, etc. on the cement surface, that is, pasting with cement and water glue. This technology not only has slow construction speed and high technical requirements, but also the wall and floor tiles are easy to fall off due to the large shrinkage rate of cement solidification. In recent years, the floor covering material plastic floor tiles have come out, but the bonding with the cement surface has become a difficult problem for interior decoration. Although there are many kinds of construction adhesives now, there are no special adhesives that satisfy the bonding of wall tiles and flooring materials with cement surfa...
