Abstract

The invention provides a composite damping sound-proof felt and a preparation method thereof, relating to the field of high-polymer composite materials. The composite damping sound-proof felt is prepared from the following components in parts by weight: 20-30 parts of polyvinyl chloride, 6-16 parts of nitrile-butadiene rubber, 8-18 parts of ethylene propylene diene monomer rubber, 30-80 parts of halogenated butyl rubber, 15-25 parts of barite powder, 6-10 parts of quartz powder, 3-5 parts of aluminum powder, 5-10 parts of calcium carbonate powder, 10-15 parts of fly ash, 1-9 parts of flame retardant, 4-8 parts of anti-aging agent, 2-6 parts of defoaming agent, 5-15 parts of acrylate, 2-10 parts of plasticizer and 1-5 parts of vulcanizing agent. The sound-proof felt provided by the invention has the advantages of favorable damping and sound-proof properties, favorable aging resistance and longer service life.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to a composite damping sound insulation felt and a preparation method thereof. Background technique [0002] Sound insulation felt is also called sound insulation felt. It is a flexible high-density coil made of rubber and polymer materials as the main raw materials. It is mainly used to match with gypsum board for sound insulation of walls and ceilings. It is also used in sound insulation and damping of pipelines and mechanical equipment. [0003] However, the sound insulation felts currently on the market are mainly made of ordinary materials, and most of them are used in a single form, which cannot effectively absorb high, medium and low frequency sound waves at the same time, and the sound insulation effect is not ideal; in addition, sound insulation felts made of ordinary materials are anti-aging The effect is not good, and the service life is short.
