Abstract

The invention discloses an automobileplasticsoundproofplate which is prepared from, by weight, 30-35 parts of quartz sand, 16-20 parts of aerosol, 22-28 parts of nano calcium carbonate, 10-15 parts of nano silver, 26-30 parts of graphene, 40-46 parts of polyvinyl chloride, 20-25 parts of polyurethane, 10-15 parts of acrylic cotton, 7-9 parts of silicon oil, 17-21 parts of fatty acid amide, 5-10 parts of oleamide, 5-12 parts of erucyl amide, 14-20 parts of sodium polyacrylate, 25-26 parts of hydroxypropyl methyl cellulose, 7-13 parts of methyl acrylate, 4-8 parts of lead sulfate tribasic, 2-8 parts of aluminum stearate, 11-15 parts of ceramic microbead, 14-18 parts of vermiculite powder and 7-8 parts of tetrapod-like zinc oxide whisker. The automobile plastic soundproof plate is high in structural density and good in soundproof effect, has certain water absorbing performance, is long in service life and has an antibacterial function.

Description

technical field [0001] The invention relates to an automobile plastic sound insulation board and a preparation method thereof. Background technique [0002] Automobile sound insulation is based on the performance of the vehicle, the corresponding road conditions, and the conditions of use, and the engine noise generated by the automobile, the resonance sound of vibration between the tire and the road surface, and the friction sound caused by the extrusion force of the components in the compartment due to gaps or aging, etc. Handling to improve the comfort of the car ride. [0003] In the sound insulation process of a car, it is necessary to install a sound insulation panel at the bottom of the car to achieve the sound insulation effect. General objects have sound insulation effects, but we take the average sound insulation (in an infinite space, place a distance between the sound source and the measured point) Infinity material) more than 30dB boards are called sound insula...
