Abstract

The invention discloses a preparation method of a nanoscale sound insulation glass material. Specifically, a Cu-BTC-SiO2 nanomaterial, ethyl orthosilicate, triethyl phosphate, calcium nitrate terahydrate, lanthanum nitrate hexahydrate and anhydrous sodium carbonate are adopted as the main raw materials, a calcining process is employed to prepare a silica ceramic carrier, the silica ceramic carrieris loaded to a porous organic metal complex Cu-BTC to obtain a high strength Cu-BTC-SiO2 skeleton material, and sound insulation functional particles are evenly distributed in a glass precursor according to the volume complementary filling principle and fuses with glass to form elastic interface bonding, therefore the spatial topological advantages of the metal modified skeleton structure can bebrought into full play. The preparation method provided by the invention is green and environment-friendly, and has little influence on the environment, the obtained product has good sound insulationperformance and wide application range, can be widely applied in the preparation process of various sound insulation glass, and plays an excellent sound insulation role.

Description

technical field [0001] The present invention relates to a method for preparing a nanoscale sound-insulating glass material, which belongs to the field of glass material preparation. Background technique [0002] Sound-insulating glass is a glass product that has a certain shielding effect on sound. It is usually a laminated glass with a multi-layer or multi-layer composite structure. The sound insulation effect can be achieved through the structural design of the glass or the weakening of the sound transmission by the interlayer material. The common soundproof glass in the market is divided into insulating glass, vacuum glass and laminated glass. These glasses produce sound insulation effect from the glass body structure and material level, but in places with high noise requirements, ordinary soundproof glass is far away. not enough. Contents of the invention [0003] The object of the present invention is to provide a nano-scale sound-insulating glass material and a pr...
