Problems solved by technology

Soft elastic materials such as rubber, sound insulation felt, etc. need to bond the structural layer multiple times, and the process is slightly complicated. The damping value provided by this type of material is tanδ<0.3, and the sound insulation effect is limited and decreases with the aging of the material; high viscoelasticity The effect of molecular polymer as a damping layer is outstanding, but due to technical and process reasons, many such products on the market have different performances in sound insulation, humidity, temperature, aging and other factors.

Abstract

The invention discloses a nano-modified water-based weather-resistant sound isolation adhesive. The nano-modified water-based weather-resistant sound isolation adhesive consists of an acrylate polymer emulsion, an organic silicone modified acrylate copolymer emulsion, a tackifier emulsion, a filler, water, a dispersing agent, a wetting agent, nano-powder aqueous dispersion, a sterilizing agent, a PH value regulating agent, a de-foaming agent and a thickening agent. A preparation method of the nano-modified water-based weather-resistant sound isolation adhesive comprises the steps of emulsion polymerization, emulsion blending, filler slurry preparation, mixture nano-modification and finished product synthesis. The nano-modified water-based weather-resistant sound isolation adhesive has the advantages of wide temperature range, wide frequency, high damping platform, high peeling strength, energy conservation, environment friendliness and light weight; the cost is saved, the construction difficulty is lowered, and the effective space utilization rate is greatly improved. Due to modification of a nano material, the nano-modified water-based weather-resistant sound isolation adhesive is wide in temperature range, good in moisture protection, resistant to heat, light, salt spray and the like, good in ageing resistance, wide in using environment range, high in sound isolation efficiency and high in using value. The sound isolation adhesive is aqueous, has environment-friendly and pollution-free effects, and belongs to novel energy-saving and environment-friendly high molecular materials.

Description

technical field [0001] The invention belongs to the field of sound-insulating glue, in particular to a water-based weather-resistant sound-insulating glue and a manufacturing method thereof. Background technique [0002] Noise pollution has become one of the world's three major pollutions alongside air pollution and water pollution. Especially in some construction fields, traffic fields, industrial production fields, entertainment places and other noise pollution is particularly serious. The sound insulation problem seriously affects people's health, study, work and life, and is generally valued by people. Sound insulation and noise reduction often have to solve two types of problems, one is to prevent noise sources from interfering with the external environment; the other is to prevent external noise from interfering with the internal space. The traditional sound insulation and noise reduction methods are divided into three types in terms of treatment methods: noise source...
