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 prepared prepolymer into the middle of the two layers of glass that have been sealed, and gradually heat up in the heating furnace to make it heat and solidify. The production cycle of this method is as long as 24~ 36 hours, the temperature is required to be 80-100°C, and the cost is quite high
The laminated safety glass produced by the light-curing adhesive method has the following disadvantages: (1) It is easy to age, the bonding strength is not high, and it is easy to fail and fall off after a long time, causing accidents
(2) The adhesive cannot adapt to changes in ambient temperature and has a greater impact on the bonding strength of the glass. The plasticizers DBP and DOP used will harden and become brittle over time
(3) After the laminated safety glass is impacted and broken, the retention rate of the fragments is only about 60%, which is not safe
(4) It cannot prevent the atomization of rain and dew, and cannot prevent the adhesion of ice and snow
(5) Can not absorb ultraviolet light from 200 to 380nm and near-infrared light from 780 to 1500nm
