Abstract

The invention discloses a food-grade anti-corrosion lining rubber plate which is prepared from the following raw materials in parts by weight: 70-85 parts of 1# natural rubber, 15-30 parts of butadiene styrene rubber 1502, 2-5 parts of a peptizer, 10-20 parts of high styrene, 30-50 parts of sulphur, 10-30 parts of graphite powder, 10-30 parts of carbon black N550, 2-8 parts of magnesium oxide, 1-3 parts of stearic acid and 1-3 parts of an accelerant DOTG. The food-grade anti-corrosion lining rubber plate is high in mechanical property, excellent in food sanitation performance and high in chemical stability and permeation resistance; furthermore, a processing technology is safe and reliable, low in cost and suitable for production equipment in the food industry.

Description

technical field [0001] The invention relates to an anti-corrosion lining rubber plate, more specifically, to a food-grade anti-corrosion lining rubber plate suitable for production equipment in the food industry, and belongs to the technical field of rubber industry anti-corrosion. Background technique [0002] In the food industry, since a lot of acid and alkali are used in the food production process, the anti-corrosion requirements for equipment are very high. At present, the production equipment used in the food industry usually uses food-grade stainless steel materials, such as 304, 316L, etc., to meet the requirements of food safety. However, the price of food-grade stainless steel equipment is generally high. Based on this, the industry proposes to line the equipment with anti-corrosion Rubber, to achieve anti-corrosion of equipment, but at present this type of product mainly depends on imports, which is expensive and has a large investment cost, so it is difficult to...
