Abstract

The invention discloses an interface finishing agent used for improving adhesion strength of polyurethane film and organic glass interface. Transparent solution of the polyurethane is obtained by dissolving the polyurethane film in certain solvent, long molecular chains of acrylic acid polymer are obtained by polymerization of acrylic acid homologues started in the solution and graft or interpenetrating polymer network system of the two is formed by controlling the reaction condition. When in use, the network system is compatible with PU and PMMA respectively to form a transition bridge between the PU and the PMMA, thereby improving the compatibility of the two interfaces and interface adhesion strength, however, transmittance of the raw base material can not be reduced and side effect towards organic materials dose not exist. Adhesion strength of the polyurethane film and organic glass interface can be improved about 40 percent after the finishing agent is applied.

Description

An interface treatment agent for improving the bond strength of polyurethane film and plexiglass interface technical field The invention relates to an interface treatment agent for bonding heterogeneous transparent materials, which can be used for manufacturing laminated glass and other transparent parts. Background technique In the compounding process of heterogeneous transparent materials, such as the compounding of inorganic glass and organic glass (PMMA, polymethyl methacrylate), polyurethane (PU) film thermal compounding technology is now used. That is, under high temperature and high pressure, polyurethane film is used as a bonding material, and the process of spreading and infiltrating on the surface of inorganic glass and organic glass respectively occurs, and finally the two are combined into a whole. Since the linear expansion coefficients of inorganic glass and oriented organic glass differ by nearly an order of magnitude (8.6×10-6°C-1 and 7.15×10-5°C-1 respecti...
