preparation example Construction

[0038] Specifically, a method for preparing sound-insulating glass, comprising the following steps:

[0039] (1) Preparation of phenyl silicone rubber-polyurethane blend

[0040] adding hexamethyldisilazane to fumed silica and mixing uniformly to obtain hexamethyldisilazane-modified fumed silica;

[0041] Put phenyl silicone rubber raw rubber, hexamethyldisilazane-modified fumed silica and diphenylsilanediol into a kneader at room temperature and knead, and vacuumize at 150°C for 1 hour to obtain a mixed rubber ;

[0042] Put the compounded rubber and polyurethane into the double-roller mill respectively. After 2 minutes of milling, mix the compounded rubber and polyurethane and add the vulcanizing agent. Press and vulcanize for 10 minutes, after stripping and drying, the phenyl silicone rubber-polyurethane blend rubber is obtained;

[0043] (2) Preparation method of sound-proof glass

[0044] Coat the top and bottom surfaces of the flint glass column with a radius of 5 mm...

Embodiment 1

[0047] The radius of the flint glass column is 4mm, the height of the flint glass column is 6mm, the thickness of the upper glass plate and the lower glass plate are both 6mm, the thickness of the phenyl silicone rubber-polyurethane coating is 3mm, and the distance between the resonator units is 80mm.

Embodiment 2

[0049] The radius of the flint glass column is 5mm, the height of the flint glass column is 8mm, the thickness of the upper and lower glass plates is 6mm, the thickness of the phenyl silicone rubber-polyurethane coating is 2mm, and the distance between the resonator units is 90mm.

Abstract

The invention discloses sound insulation glass. The sound insulation glass comprises a glass substrate and a plurality of resonator units, wherein the glass substrate is provided with a hollow cavity,and the plurality of resonator units are dispersed in the hollow cavity and form a photonic crystal with the glass substrate. When the sound insulation glass is applied to glass decoration, the technical scheme of the invention can improve the isolation effect of the glass decoration on low-frequency noise and meet the user requirements.

Description

technical field [0001] The invention relates to the technical field of sound-insulating materials, in particular to a sound-insulating glass. Background technique [0002] In recent years, the advancement of urbanization and the rapid development of industrial enterprises have not only facilitated people's lives, but also caused a series of environmental problems, including noise pollution. Noise is the main source of environmental pollution that affects people's work and living comfort. The normal hearing range of the human body is 20Hz-20000Hz, and the sound with a frequency of 20Hz-500Hz is low-frequency noise. The sound waves of low-frequency noise are relatively long, and can pass through obstacles, run long distances and penetrate walls and enter human ears. Low-frequency noise not only causes functional damage to the human body, but may also cause organic damage and mental damage. There are five main sources of low-frequency noise: elevators, transformers, high-rise...
