Abstract

The invention discloses an antiseptic rubber lining which comprises 20-40 parts of nature rubber, 8-16 parts of butadiene styrene rubber, 0.5-1.5 parts of peptizer, 8-16 parts of high styrene, 10-20 parts of graphite powder, 20-30 parts of sulfur, 0.5-2 parts of high-speed accelerator and 2-4 parts of dispersing agent. The invention also discloses a preparation method of the antiseptic rubber lining. The antiseptic rubber lining disclosed by the invention has excellent corrosion resisting property on various acid and alkali media; and the problem of the corrosion resisting property of a steelmaterial is solved, so that the effective service life of a steel member can be prolonged by 10 to 20 years; and the lining is applied to a smoke absorption column in a waste incineration factory, a kettle operating at a high temperature, a storage tank and other steel members, and has the characteristics of excellent combination property, high hardness, high-temperature resistance, pressure resistance, wearing resistance, tension stress, good ductility and the like. The preparation process is simple, can be used in a workshop or in site operation, and the hot water or steam is used for vulcanization, thereby being easy to realize.

Description

technical field [0001] The invention relates to the field of chemical anticorrosion materials, in particular to an anticorrosion rubber lining and a preparation method thereof. Background technique [0002] The pure steel equipment used in the production process of the chemical industry and metallurgical industry, such as containers, has been subject to internal and external corrosion of different chemical substances, and it is prone to rust and wear after a long time, which will cause damage to the equipment and seriously affect Production Process. Corrosion of steel structure materials has been a problem that has plagued all walks of life. Due to the high temperature and high pressure resistance of steel structure materials, other materials such as plastics cannot be replaced. Therefore, the surface of steel structure materials can be anti-corrosion without affecting the characteristics of steel materials Processing research is of great significance. [0003] In the prio...
