Abstract

The invention discloses a preparation method of laminated glass glue with high bonding strength, and belongs to the technical field of glass glue preparation. According to the preparation method provided by the invention, a self-made polyurethane acrylate prepolymer is used as a matrix, modified silica sol and self-made fruit wine are used as reinforcing substances, and the laminated glass glue isprepared with the supplement of a coupling agent and modified self-made reaction materials. Contained acrylates have double bounds with polymerization reaction activity, and free radicals can be polymerized under the action of illumination, so that crosslinking and solidification are carried out among polyurethane acrylate macromolecular chains, and the bonding strength is improved. According tothe preparation method, in the process of polymerization reaction, due to the steric hindrance effect of methyl in toluene diisocyanate molecules, the para-position reaction activity is usually largerthan the ortho-position reaction activity, and an effect of fast crosslinking and solidification is exerted. According to the preparation method, the silica sol is modified by a silane coupling agentand an alcohol solution, so that the bonding strength is strengthened by a network structure, the bonding property between the laminated glass glue and glass is enhanced, and thus the preparation method has a wide application prospect.

Description

technical field [0001] The invention discloses a preparation method of high bonding strength laminated glass glue, which belongs to the technical field of glass glue preparation. Background technique [0002] Laminated glass glue, also known as laminated safety glass glue, is a one-component anaerobic light-curing laminated glass glue, Doyer purple light modified acrylate adhesive, which is a colorless and transparent liquid, which is cured by isolating sunlight, ultraviolet rays and oxygen. . The material is endowed with a variety of unique functional properties, such as sound insulation, antistatic, vibration reduction, noise reduction, wave absorption, anti-aging, impact resistance and other properties. [0003] Laminated glass is a composite material in which glass and glass are separated by an intermediate layer and bonded together through treatment. It is generally used for the manufacture of safety glass, bulletproof glass, architectural decorative glass, art glass, ...
