Tear-resistant absorption nano-modified rubber and preparation method thereof

Abstract

The invention discloses tear-resistant absorption nano-modified rubber and a preparation method thereof. The tear-resistant absorption nano-modified rubber comprises the following raw materials: chlorohydrin rubber, nitrile-butadiene rubber, acrylonitrile-butadiene copolymer rubber, diene rubber, styrene-butadiene rubber and regenerated rubber. By the matched use of the chlorohydrin rubber, the nitrile-butadiene rubber, the acrylonitrile-butadiene copolymer rubber, the diene rubber, the styrene-butadiene rubber and the regenerated rubber as main materials, the material toughness is greatly improved, the problem of high breakage probability of a conveying belt is effectively solved, and meanwhile, gas harmful to a human body cannot be generated at a higher temperature; high temperature resistance, tear resistance and other properties are perfectly integrated, so that the tear-resistant absorption nano-modified rubber disclosed by the invention can be applied to various harsh conditions. Adopted chitosan can absorb negatively-charged bacteria as molecules are positively-charged, so that a bactericidal function is achieved; structurally, fiber membrane layers with different diameters and pores are prepared; by means of nano grapheme between a bonding layer and a layer, the porosity and the specific surface area of a composite absorption membrane are improved, and the effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a tear-resistant adsorption nano-modified rubber 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 mainly caused by man-made envir...
