Problems solved by technology

For now, domestic standards do not make special requirements for the high-temperature medium resistance of hard rubber, nor do they require high-temperature adhesion between the lining and the steel substrate. In terms of performance, they cannot meet the requirements for use in the eleventh-stage flash evaporation unit.

Abstract

The invention relates to an anti-corrosion rubber composition. The anti-corrosion rubber composition comprises the components of, by weight, 100 parts of raw rubber, 20-80 parts of talcum powder, 10-60 parts of mica powder, 0.5-10 parts of coupling agent, 0.5-15 parts of pitch, 1-20 parts of coumarone resin, 30-60 parts of sulphur, 0.1-5 parts of accelerant and 1-20 parts of dyeing agent. The invention also relates to an anti-corrosion rubber lining. The rubber lining produced through the anti-corrosion rubber composition provided in the invention can bear a working temperature of 130 DEG C under a high vacuum degree, is acid and alkali resistant at high temperatures and is applicable to a 11-stage flash device of an adhesive production line.

Description

technical field [0001] The invention relates to the field of chemical anti-corrosion materials, in particular to an anti-corrosion rubber composition and an anti-corrosion rubber lining. Background technique [0002] In the 1980s, a number of viscose production lines were introduced in China. Among them, the eleven-stage flash evaporation device showed high efficiency, energy saving and stability, which brought new technological breakthroughs to the domestic viscose industry. However, the high price of imported equipment has become a bottleneck restricting the development of the domestic viscose industry. Therefore, it is urgent to seek the localization of the eleven-stage flash evaporation unit. The development of the matching anti-corrosion rubber lining has also been put on the agenda as one of the key factors. [0003] In the eleven-stage flash evaporation device, the use conditions of the anti-corrosion rubber lining are relatively harsh, and the following requirement...
