Tear-resistant nano-modified rubber for controlling noise and preparation method thereof

Abstract

The invention discloses tear-resistant nano-modified rubber for controlling noise and a preparation method thereof. The tear-resistant nano-modified rubber comprises, by weight, 5-8 parts of dimethyl vinyl ethyoxyl silane, 4-6 parts of fatty alcohol-polyoxyethylene ether sodium sulfate, 8-10 parts of allophane powder, 15-20 parts of maleic anhydride grafted polyvinyl chloride, 50-70 parts of polystyrene, 20-30 parts of polyisocyanurate, 5-8 parts of glass pumice, 4-6 parts of porous manganese slag, 6-8 parts of hollow microbeads, and the like. The tear-resistant nano-modified rubber has the advantages that the dimethyl vinyl ethyoxyl silane and the fatty alcohol-polyoxyethylene ether sodium sulfate are used to modify the allophane powder, the even distribution of the allophane powder in a polymer base material is benefited, the compatibility of the allophane powder with the polymer base material is increased, the modified allophane powder is added into plastics, and the flame retardance of the plastics can be increased evidently; the compatibilizer used by the tear-resistant nano-modified rubber is the maleic anhydride grafted polyvinyl chloride, the maleic anhydride grafted polyvinyl chloride is combined with the polystyrene to allow the polyisocyanurate, the glass pumice, the porous manganese slag, the hollow microbeads and the like to be well dispersed in a polystyrene base, incident sound waves borne by the composite material can be well blocked, the sound insulation performance of the composite material is increased, the composite material does generate gases harmful to human bodies under high temperature, performances such as high temperature resistance and tear resistance are perfectly fused, and the tear-resistant nano-modified rubber can be applied to various severe working conditions.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a tear-resistant nano-modified rubber used for preventing and controlling noise and a preparation method thereof. Background technique [0002] Smog is a mixture of fog and haze. When the humidity is high in the morning and evening, the composition of fog is more. When the humidity is low during the day, haze dominates, and the relative humidity is between 80% and 90%. Among them, fog is a natural weather phenomenon, and the water vapor in the air is dense. Although dust is used as condensation nuclei, it is generally non-toxic and harmless; the core substance of haze is smoke, dust and other substances suspended in the air. The relative humidity of the air is lower than 80%, and the color is yellow. The gas can directly enter and adhere to the lower respiratory tract and lung lobes of the human body, which is harmful to human health. The formation of smog weather is ...

Problems solved by technology

The formation of smog weather is mainly caused by man-made environmental pollution, coupled with natural conditions such as low temperature and wind, which make it difficult for pollutants to spread
