Problems solved by technology

[0002] Existing laminated safety glass, such as laminated safety glass used for windshields of automobiles, laminated safety window glass of high-rise buildings and laminated furniture glass, etc., although the light transmittance is high, they cannot play the role of heat insulation, bulletproof and fire prevention. , cannot prevent rain and dew atomization and ice and snow adhesion, nor can it absorb glare and 200-380nm ultraviolet rays, let alone absorb 780-1500nm near-infrared rays
Because the existing laminated safety glass is prepared by the following formula technology: (1) Polyvinyl butyral film method: Cut polyvinyl butyral into the required film base, sandwich it between two layers of glass It is made by heating and pressing with a heat-sealing machine. This method has very high requirements for the film, that is, the film must be free from scratches and defects, and the thickness must be very uniform. The cost of raw materials is high, and the investment in equipment is huge.
(2) Thermal polymerization glue filling method: pour the pr
