Anti-blooming agent for rubber

Abstract

The invention discloses an anti-frosting agent for rubber, and relates to a polymer. The anti-frosting agent comprises the following main raw materials in percentage by mass 25-40% of microcrystalline wax, 20-30% of polyethyleneglycol, 6-10% of paraffin emulsifier, 10-15% of epoxy resin, 1-1.5% of hydrocarbon resin and 10-35% of silicon dioxide. According to the invention, free substances in a rubber product do not migrate any more and are immobilized, so that the rubber product has lasting beautiful appearance, and the service performance and service life of the rubber product are greatly improved.

Description

technical field [0001] The invention relates to a polymer, in particular to an anti-blooming agent for rubber. Background technique [0002] Since the reform and opening up, my country's rubber industry has developed rapidly, the types of products have become more and more perfect, and the import and export trade has continued to grow. However, due to the late start of my country's rubber industry, weak foundation, backward technology, outdated equipment, few types of raw materials, incomplete varieties, and quality fluctuations The large gap between the product quality and the level of developed countries and regions is still relatively large. Therefore, under today's trade globalization and market diversification, the competitiveness of my country's rubber products in the international high-end field is poor. The market share is low. [0003] Blooming is relatively common in rubber products. It is a phenomenon that the liquid or solid compounding agent migrates from the ins...

Problems solved by technology

[0004] In terms of the quality of rubber products, frost spraying on the surface is a serious appearance quality problem. Every year, rubber products in my country cause economic losses and social impacts on enterprises due to frost spraying on the surface. Frost spraying on the surface of rubber not only affects the appearance of the product Quality and service life, but also affect the processing performance and process performance of rubber semi-finished products. As an anti-blowout agent, the advantage of microcrystalline wax is that it is cheap, but it can only delay the spraying effect, and still needs to be migrated and sprayed out, treating the symptoms but not the root cause, so it is still very important to design a blowout preventer for rubber market application prospects
