Abstract

The invention relates to a glass laminating glue. The glass laminating glue comprises 100 parts of polymethyl methacrylate, 15-20 parts of polyurethane resin, 3-8 parts of zirconia microspheres, 6-8 parts of silica microspheres, 10-20 parts of modified LDHs, 2-5 parts of phytic acid and 0.1-1 part of rare earth oxide, wherein the modified LDHs are prepared by the following steps: dispersing a water-soluble divalent metal salt, a water-soluble trivalent metal salt and a precipitant in water, dropwise adding a polyphosphate solution, and performing a reaction at 80-100 DEG C for 6-36 h. The modified LDHs are intercalated and modified with the polyphosphate, so the modified LDHs have a good flame retardant effect; the modified LDHs are added to the polymethyl methacrylate matrix, so the glasslaminating glue has good flame retardancy; and the zirconia microspheres, silica microspheres and phytic acid are added, so the glass laminating glue has excellent resistance to the high temperatureand radiation.

Description

technical field [0001] The invention relates to the technical field of glass production and manufacturing, in particular to a glass laminate. Background technique [0002] Laminated glass is laminated glass, which is sandwiched between two or more pieces of glass with one or more layers of organic polymer interlayer film (glass interlayer). After special high temperature and other processes, the glass and interlayer film are permanently A bonded composite glass product. [0003] Laminated glass is a kind of safety glass, which has good impact resistance, penetration resistance, safety, noise reduction, UV protection, etc. With the development of the times, laminated glass is widely used in architectural doors and windows, lighting ceilings, skylights, suspended ceilings, aquariums, etc. due to its unique properties. As people's demand for laminated glass becomes more diversified, not only the original characteristics of the glass are required, but also other special proper...
