Embodiment Construction

[0007] Food-grade anti-corrosion lining rubber sheet, characterized in that: the weight ratio of the main and auxiliary raw materials is as follows: natural rubber 3L: 60-70 parts, styrene-butadiene rubber 2000: 25-35 parts, magnesium oxide: 2-3 parts, carbon Black N330: 3-8 parts, M grade bakelite powder: 60-70 parts, third-line oil: 2-5 parts, sulfur: 30-36 parts, accelerator: 1-2 parts. The weight ratio of the main and auxiliary raw materials of the M-grade bakelite powder is as follows: 3L of natural rubber: 100 parts, sulfur: 40-45 parts, and 1-2 parts of vulcanizing agent. In actual implementation, the formula of food-grade rubber lining requires absolutely non-toxic additives, dense and stable structure after vulcanization, the bonding strength meets the requirements, and the insulation performance guarantees 3000V / mm electric spark detection. Among the above formula materials, except M grade Except bakelite powder, the rest can meet the requirements. Ordinary bakel...

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...
