Problems solved by technology

Use hot-melt glue or polystyrene glue, which contains more than 40% low-molecular solvents, which is not conducive to the health of decoration construction workers; in China, epoxy resin is mainly used to make glue on site, which is inconvenient for construction; epoxy resin is also used. Or acrylic acid to prepare two-component adhesives, but there are disadvantages such as high brittleness, large volatile content, air pollution, low viscosity of glue, flowing phenomenon and short shelf life.

Description

technical field [0001] The invention relates to the field of chemical raw materials, in particular to vinyl ester resin building reinforcement glue and a preparation method thereof. Background technique [0002] With the vigorous development of the construction industry and the widespread application of building structure rubber-to-reinforcement technology, the amount of adhesives is increasing. The original bonding process and adhesives have many deficiencies. Use hot-melt glue or polystyrene glue, which contains more than 40% of low-molecular solvents, which is not conducive to the health of decoration construction workers; in China, epoxy resin is mainly used to make glue on site, which is inconvenient for construction; epoxy resin is also used. Or acrylic acid to prepare two-component adhesives, but there are disadvantages such as high brittleness, large volatile content, air pollution, low viscosity of glue, flowing phenomenon and short shelf life.
