Abstract

The invention provides a sound-absorbing and sound-insulation material. The sound-absorbing and sound-insulation material comprises the following components in parts by weight: 10-15 parts of rubber,10-15 parts of PVC, 10-15 parts of a foaming agent, 18-24 parts of a filler, 3-7 parts of carbon black, 17-22 parts of paraffin, 2-5 parts of chlorinated polyethylene, 1-5 parts of slab beeswax, 1-4 parts of soybean oil, 0.5-3 parts of a surfactant and 0.5-4 parts of calcium stearate. By adding a mixed material comprising the PVC, the rubber and the foaming agent, and optimizing the usage amountsof the components, the purpose that the prepared material has large and small holes can be effectively achieved; and the overall sound-absorbing performance of the sound-absorbing material is effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of noise-reducing materials, and in particular relates to a sound-absorbing and sound-insulating material and a method for preparing the sound-absorbing and sound-insulating material. [0002] technical background [0003] In today's society, various high-speed vehicles, industrial equipment, construction machinery, household appliances and audio equipment are widely used, resulting in increasingly serious noise pollution in our living environment. It will not only affect people's normal work, study and life, but also harmful People's physical and mental health will also affect the normal operation and service life of some precision instruments and equipment, so noise pollution is one of the four major public hazards that we urgently need to solve. [0004] We all know that sound is caused by the vibration of objects. From a physical point of view, noise refers to the sound produced by an object doing a seri...
