Problems solved by technology

[0011]Synthetic rubber is usually not easy to be split by mold, but because plasticizers, stabilizers, fillers, lubricants and other processing aids are often added to the products, especially Plasticizers, such substances are more sensitive to mold, so that synthetic rubber products are also vulnerable to mold erosion and damage
Generally speaking, the molecular weight of plasticizers added during the processing of rubber products is low, such as the molecular weight of phthalates does not exceed 400, and they will migrate from the inside of the product to the surface of the product with the prolongation of use time, especially It is more susceptible to the attack of mold and bacteria under the conditions of high temperature, high humidity, and shade, which encourages their reproduction, discolors the surface of the product, produces spots, and even pores, which affects the normal function of rubber products.

Abstract

The invention belongs to the field of rubber, and particularly relates to moldproof rubber. The moldproof rubber comprises the following components in parts by weight: 80-200 parts of epoxidized natural rubber, 50-200 parts of ethylene propylene diene monomer, 2-10 parts of nano zinc oxide, 1-4 parts of sodium stearate, 15-50 parts of carbon black N100, 2-12 parts of carbon black N330, 4-15 parts of mold preventive, 2-10 parts of sulfur, 1-5 parts of anti-aging agent, 1-6 parts of paraffin, 1-5 parts of aromatic oil, 1-5 parts of white carbon black, 1-5 parts of anti-scorching agent, 1-4 parts of dibutyl phthalate, 1-4 parts of zinc diethyl dithiocarbamate, 1-4 parts of 2-mercaptoimidazoline and 1-10 parts of plasticizer. Compared with the existing rubber, for the moldproof rubber provided by the invention, the added mold preventive composition greatly enhances the moldproof effect; and the rubber also has the advantages of high tensile strength, fire resistance, corrosion resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to an anti-mold rubber with antibacterial and anti-mold properties. [0002] Background technique [0003] Microorganisms are widely distributed in the natural environment in which humans live. Many microorganisms are beneficial to humans, such as yeast, actinomycetes and bacteria, and many species have become indispensable components in human production and life. In the pharmaceutical industry , food industry, agricultural pest control and other aspects, have played an important role. [0004] But there are also many microorganisms that have caused serious harm to humans. They can cause mildew and corruption of items, and have a great impact on industrial production and human health. For example, the toxin of Aspergillus flavus has carcinogenic effects on the human body. Since ancient times, humans have been fighting against harmful molds in various ways. At t...
