Sound-insulation and thermal-insulation laminated glass and preparation method thereof

Abstract

The invention relates to the technical field of glass, in particular to sound-insulation and thermal-insulation laminated glass and a preparation method thereof. The sound-insulation and thermal-insulation laminated glass comprises a film clamped between a first glass sheet and a second glass sheet, wherein one side, close to the film, of the first glass sheet and/or the second glass sheet is coated with a sound-insulation and thermal-insulation glue layer which is 15-20 mu m thick; the sound-insulation and thermal-insulation glue layer is prepared from substances in parts by weight as follows: 80-100 parts of a waterborne polyurethane emulsion, 0.01-0.2 parts of a leveling agent, 0.01-0.2 parts of a defoaming agent, 5-15 parts of glass beads, 1-9 parts of titanium dioxide, 1.5-5 parts of coated particles and 180-200 parts of water; titanium dioxide contained in the glue layer can scatter the passing light rays effectively, so that the light rays are prevented from transmitting through the laminated glass directly, and good thermal insulation effect of the laminated glass is guaranteed; meanwhile, each glass bead is of a hollow structure and has lower heat conducting coefficient and good chemical stability, and the glass beads contained in the sound-insulation and thermal-insulation glue layer have good thermal insulation performance.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a sound-insulating and heat-insulating laminated glass and a preparation method thereof. Background technique [0002] In modern society, glass plays more and more important roles, and glass has become an indispensable product in residential buildings, office buildings, car windows and other places. For a long time, the glass material is characterized by being fragile, and the thinner it is, the more fragile it is. When the glass breaks, the fragments are easy to splash, which is easy to hurt people and pollute the environment. Although the impact resistance of tempered glass is enhanced, the fragments will still splash when the glass explodes, affecting safety. For this reason, people have developed a kind of laminated glass, which consists of two or more pieces of glass with one or more layers of organic polymer interlayer film sandwiched between them. After processing, the gla...
