Sound isolation material and preparation method thereof

Abstract

The invention provides a sound isolation material, which is prepared from the following raw materials in parts by weight: 40 to 50 parts of poly1,3-adamantane benzylidene diformyl chloride malononitrile dihydroxyethyl amine ester, 5 to 10 parts of 2,3,4,5,6-pentafluorostyrene, 5 to 10 parts of 2-adamantil acrylate, 5 to 10 parts of polymerization monomers, 0.3 to 0.5 part of initiators, 2 to 5 parts of cubic aluminum oxide, 2 to 5 parts of flaky aluminum oxide, 2 to 5 parts of leaf type aluminum oxide, 1 to 3 parts of coupling agents and 80 to 100 parts of dimethylsulfoxide. The invention alsodiscloses a preparation method of the sound isolation material. The sound isolation material disclosed by the invention has the advantages that the sound isolation effect is obvious; the preparationcost is low; the use is safe; the environmental-friendly effect is achieved in the use process; the mechanical performance, the weather resistant performance and the fireproof performance are excellent.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a sound-insulating material and a preparation method thereof. Background technique [0002] With the development of social economy and the increase of industrial factories, vehicles and entertainment places, a large number of factory mechanical operation sounds, vehicle whistles and entertainment places are full of people's lives, causing a new type of pollution- sound polution. These noise pollutions have brought serious interference to people's normal life, work and study. Therefore, how to control noise pollution and reduce the impact of noise on people's lives is an urgent problem to be solved at present. [0003] The use of sound insulation materials is one of the effective measures to control noise pollution. Sound insulation materials refer to a class of materials, components or structures that can block sound transmission or reduce transmitted sound energy, ...

Problems solved by technology

[0007] In order to overcome the defects in the prior art, the present invention aims to provide a sound-insulating material and a preparation method thereof. The preparation method is simple and easy, and the preparation cost is low; the sound-insulating material prepared by the preparation method overcomes the traditional sound-insulating material or The more or less existing materials are thick and heavy, difficult to install and transport, difficult to absorb and transmit sound energy and have strong reflection, unsatisfactory sound absorption effect, poor flame retardancy and weather resistance, and serious technical problems to the environment. It has the advantages of remarkable sound insulation effect, low preparation cost, safe and environmentally friendly use, excellent mechanical properties, weather resistance and flame retardancy
