Abstract

The invention relates to a low cost and high efficient soundproof material and a manufacturing method thereof, relates to the field of soundproof materials, solves the problems that in the prior art, soundproof materials do not have a prominent soundproofing effect, generate harmful gas, which can harm the human health, and have a high cost; and provides a low cost and high efficient soundproof material. The soundproof material comprises thermoplastic resin and an inorganic filling material, wherein the surface of the inorganic filling material has been processed by a coupling agent processing liquid, the inorganic filling material accounts for 15 to 80 wt% of the total weight of the soundproof material, and the balance being thermoplastic resin. In the soundproof material, the connections among the particles are abnormal, thus the internal friction of the incident sound waves is increased by the structure of the soundproof material, and a relaxation effect is generated to absorb the sound waves. Filling materials with different particle sizes are corresponding to waves in different wavelengths or frequencies, so the soundproof material can reduce sounds in different frequencies. Moreover the soundproof material has a good soundproof effect and is suitable for being promoted and used.

Description

technical field [0001] The invention relates to a low-cost and high-efficiency sound insulation material and a manufacturing method thereof, and relates to the field of sound insulation materials. Background technique [0002] With the advancement of manufacturing technology in the automobile industry, people are paying more and more attention to the noise control in passenger cars. Due to the relatively weak domestic automobile manufacturing technology foundation, it is difficult to design the elements that affect the NVH quality of the vehicle in place during automobile R&D and design. Always carry out NVH rectification after the finished car comes out, mainly through the use of high-efficiency sound insulation materials such as the interior floor and interior decoration of the car, to block the external noise from being transmitted to the passenger compartment, so that the noise inside the car is greatly reduced, so the sound insulation of the car is efficient The perform...
