Problems solved by technology

However, although the current conventional laminated glass has a good diaphragm sound effect, it is mainly due to its structure and has not reached a high diaphragm sound level. In the long-term use of many laminated glasses, the interlayer will be affected. Problems such as water ingress due to oxidation and other effects affect the service life

Abstract

The invention discloses a preparation method of sound-insulation sandwich glass which comprises the steps: firstly, utilizing hydrogen peroxide to pretreat the surface of two-layer glass; adding phenolic resin, vinylidene chloride resin, zinc oxide, 2-ethylhexyl acrylate and ethyl orthosilicate into a reaction kettle according to parts by weight and heating and stirring under the vacuum conditionto obtain a mixture; finally, heating the mixture to a softening temperature, then filling into the middle of two layers of glass and curing to obtain the sound-insulation sandwich glass. The sound-insulation sandwich glass prepared by the method disclosed by the invention has good water resistance and heat resistance and simultaneously has good heat insulation.

Description

technical field [0001] The invention belongs to the technical field of glass preparation, and in particular relates to a preparation method of diaphragm-sound laminated glass. Background technique [0002] Laminated glass is a layer of interlayer film sandwiched between two pieces of glass. Even if the glass breaks, the shards will be stuck to the film, and the surface of the broken glass will remain clean and smooth, thus effectively preventing the shards from puncturing and penetrating. The occurrence of the falling incident ensures personal safety. Compared with ordinary glass, laminated safety glass is not easy to break, it is a relatively tough material, and it will not produce sharp fragments when broken, so the safety is guaranteed. When encountering natural disasters such as earthquakes and floods, laminated safety glass can minimize the damage. At the same time, it is also beneficial to reduce the retention of fragments inside the interlayer when it breaks, which ...
