Method for preparing mildewproof rubber by using regenerated rubber as basal body

Abstract

The invention discloses an anti-mildew rubber preparation method with regenerated rubber as a base body, which comprises five processes: raw material ratio, plasticization, mixing, sheet forming and molding, wherein, the ratio of raw materials is: 60 to 80 percent of ethylene propylene diene monomer regenerated rubber, 20 to 40 percent of ethylene propylene diene monomer, 5 to 10 percent of zinc oxide, 0.5 to 1.5 percent of stearic acid, 5 to 35 percent of carbon soot, 5 to 35 percent of light calcium carbonate, 0.5 to 1.5 percent of age inhibitor RD, 0.5 to 1.5 percent of age inhibitor MB, 0.5 to 2.0 percent of sulfur, 0.5 to 2.0 percent of accelerant M, 0.5 to 2.0 percent of accelerant TT, and 0.5 to 1.5 percent of 5, 6-dichloro benzoxazolinone, and the anti-mildew rubber is prepared through processes such as the plasticization, the mixing, the sheet forming, the molding and so on. The anti-mildew rubber has good anti-mildew performance and physical mechanical performance, fully utilizes a renewable resource of waste rubber, and reduces the cost, and contributes to environmental protection and energy conservation.

Description

technical field [0001] The invention belongs to the technical field of non-metallic materials, in particular to a method for preparing mildew-resistant rubber based on reclaimed rubber. Background technique [0002] Rubber materials are easy to breed various molds in dark, humid and hot conditions. The growth and spread of molds will secrete various enzyme-degraded materials, and can produce organic acids and other metabolites, causing direct invasion and damage to rubber materials. Severe cases even lead to the loss of its performance. Therefore, there is a need to improve the mold resistance of rubber materials.

Problems solved by technology

[0006] The disadvantages of the above technologies are: the raw rubber of rubber is used as the base material of anti-mildew rubber, and the use of recycled rubber is not involved, which is not conducive to the development and application of rubber recycling resources, and leads to higher product costs.
