Abstract

The invention relates to the technical field of laminated glass, in particular to a laminated glass interlayer film and a preparation method thereof. The preparation raw materials include: 45.00-98.00 parts of MMA, 0.02-0.20 parts of initiator and 0.50-45.00 parts of bonding monomer; the preparation method includes: 1) placing MMA, initiator and bonding monomer in a container, and Carry out heating prepolymerization, obtain intermediate solution after prepolymerization reaction finishes, intermediate solution is carried out degassing, obtain prepolymerization liquid after degassing; 2) inject prepolymerization liquid between the glass layers of laminated glass; 3) pair The laminated glass filled with the pre-polymerization solution is thermally polymerized to obtain a laminated glass with PMMA copolymer as the interlayer film. The present invention creatively introduces bonding monomers in the MMA polymerization process to ensure that the prepared laminated glass interlayer film has good light transmittance, and from the two aspects of bonding strength between it and the glass layer and thermal shrinkage Improvement is carried out so that the prepared laminated glass interlayer film has high light transmittance, high bonding strength and no heat shrinkage.

Description

technical field [0001] The invention relates to the technical field of laminated glass, in particular to a laminated glass interlayer film and a preparation method thereof. Background technique [0002] Laminated glass is a composite glass product in which one or more layers of polymer films are sandwiched between two or more pieces of glass. After special high-temperature and high-pressure processing, the glass and polymer films are permanently bonded together. It combines the high strength and weather resistance of inorganic glass with the light weight and impact resistance of organic transparent materials. As the most ideal safety glass at present, laminated glass is widely used in vehicles, buildings and public places. [0003] The polymer interlayer film is the most important component that determines the safety performance of laminated glass, and has strict requirements in terms of light transmission performance, bonding performance with glass, mechanical properties, ...
