Abstract

The invention discloses a compound sound insulation material and a preparation method thereof. The compound sound insulation material contains the following materials by weight percent: 40% of vinyl chloride acetate resin, 10-20% of low-density polyethylene, 20-30% of methyl vinyl silicone rubber, 5-10% of a high molecular compatilizer, 2-3% of a diluent, 1-5% of superfine fiber, and 1-2% of an antioxidant. The preparation method comprises the following steps: S1, weighing and preparing materials: weighing the materials according to weight percentage and marking for storage; S2, feeding and blending; S3, plastifying; and S4, performing extrusion molding. According to the invention, due to the setting of components including vinyl chloride acetate resin, low-density polyethylene, methyl vinyl silicone rubber, high molecular compatilizer, diluent, superfine fiber and antioxidant, so that the sound insulation effect of the compound sound insulation material is improved; and due to the setting of preparation procedures of weighing and preparing materials, feeding and blending, plastifying and performing extrusion molding. Therefore, the quality of the sound insulation material is promoted, and further the market competitiveness of the product is promoted.

Description

technical field [0001] The invention relates to the technical field of sound-insulating materials, in particular to a composite sound-insulating material and a preparation method thereof. Background technique [0002] At present, China's economy is developing rapidly, and qualitative changes have taken place in various fields, striving to be in line with international standards in all aspects. The same is true in the construction industry. In recent years, the problems of waterproofing and indoor pollution have increased significantly. Among them, the demolition and demolition of noise is the top one. Noise pollution has caused ubiquitous troubles to people's lives. The requirements for noise prevention will become higher and higher, and more and more individuals and institutions will change their concepts and begin to hope to improve their living and working environments, and desire to be liberated from living noise and public noise. Based on this situation, the National C...
