Food-grade anticorrosion liner rubber plate

Abstract

A food-grade anticorrosion liner rubber plate comprises, by weight, 60-70 parts of natural rubber 3L, 25-35 parts of styrene butadiene rubber 2000, 2-3 parts of magnesium oxide, 3-8 parts of carbon black N330, 60-70 parts of M-grade bakelite powder, 2-5 parts of third line oil, 30-36 parts of sulfur and 1-2 parts of an accelerant. The food-grade anticorrosion liner rubber plate has the advantages of corrosion resistance, no heavy metal pollution and reduced production cost, and is specially used in food production apparatuses and biological pharmacy industry production apparatuses.

Description

technical field [0001] The invention relates to an anti-corrosion material, in particular to a food-grade anti-corrosion lining rubber plate specially suitable for production equipment in the food and biopharmaceutical industries. Background technique [0002] In food, biopharmaceutical and other related industries, acid and alkali media are used to regenerate ion exchange resins in pure water production, mother liquor ion exchange, decolorization and other processes, which have high anti-corrosion requirements for equipment, and rubber linings are usually used equipment, but due to the inevitable existence of some heavy metal ions in the formula materials in rubber, for example, ordinary rubber is filled with ordinary bakelite powder, which is processed from waste battery shells, and contains a certain amount of zinc and mercury. , cadmium and other substances, dispersed in the rubber material will affect the quality of the material, especially the increasingly stri...

Problems solved by technology

[0002] In food, biopharmaceutical and other related industries, acid and alkali media are used to regenerate ion exchange resins in pure water production, mother liquor ion exchange, decolorization and other processes, which have high anti-corrosion requirements for equipment, and rubber linings are usually used equipment, but due to the inevitable existence of some heavy metal ions in the formula materials in rubber, for example, ordinary rubber is filled with ordinary bakelite powder, which is processed from waste battery shells, and contains a certain amount of zinc and mercury. , cadmium and other substances, dispersed in the rubber material will affect the quality of the material, especially the increasingly stringent food and drug safety requirements, so the ordinary rubber lining technology on the market cannot meet the requirements for use
