Abstract

The invention belongs to the technical field of building material preparation, and particularly relates to a preparation method of high-adhesion moisture-proof glass cement. Soybeans are used as a rawmaterial, protein extracted from the soybeans is subjected to acid heat modification, and the moisture resistance of the water-soluble adhesive is improved; citric acid in the glass cement is a stabilizer and inhibits bacterial reproduction; tourmaline powder can also provide negative oxygen ions and improve the antibacterial ability, and the anti-oxidation ability of the glass cement is enhanced. According to the method, castor oil polyurethane and methyl silicone rubber are subjected to network interpenetration; the castor oil polyurethane is used as a continuous phase in the IPN interpenetrating structure; the methyl silicone rubber as dispersion phase, the silicon rubber has an open micropore structure; after vacuum defoaming, the surface tension is very small, an interpenetrating network structure is combined more tightly, and water absorption and falling are not likely to happen after curing; the silicon rubber can form hydrogen bonds with the surfaces of glass, glass and otherbase materials, the bonding force is improved, and therefore the problem that glass cement is not firmly bonded to the surface of the glass due to too much dust is solved, and wide application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a method for preparing high-adhesion moisture-proof glass glue. Background technique [0002] Glass glue is a commonly used adhesive in household, which is composed of sodium silicate, acetic acid and organic silicone. Sodium silicate is easily soluble in water and has viscosity. It is called sodium silicate in the south and sodium silicate in the north. [0003] The production technology of domestic ordinary compound solvent-based glass glue two-component polyurethane adhesive glass glue has been fully mastered, and some manufacturers have mature technology and stable quality, which can completely replace imported products; special glue for aluminized film, anti-slip agent functional glue and other products Strong pertinence, outstanding performance, should be vigorously promoted; China's climate differences are obvious, and the conditions of l...
