Problems solved by technology

These organic solvents and oils have caused great harm to the normal use of the above-mentioned rubber lining materials, causing the lining materials to swell and damage, resulting in the rubber lining not being resistant to corrosion, shortening the service life, and not being safe and reliable for corrosion protection
Usually manifested in: lining materials with good acid and alkali corrosion resistance have poor oil and solvent resistance, while lining materials with good oil and solvent resistance have poor acid and alkali corrosion resistance, forming a pair of contradictions

Abstract

The invention relates to a high oil-resistant rubber anti-corrosive lining with acid-base corrosion resistance as well as oil and solvent resistance and a preparation method thereof. The high oil-resistant rubber anti-corrosive lining comprises the following components based on unit weight: 80 to 120 high oil-resistant rubber, 8 to 12 modified thickening agents, 5 to 40vulcanizing agents and other materials containing 40 to 60 carbon black N550, 8 to 12 white carbon black, 1.5 to 2.5 anti-aging agents 4020, 1 to 2 anti-aging agents RD and 1 to 2 promoters DM. The high oil-resistant rubber anti-corrosive lining has the advantages of resisting acid-base corrosion, solvent and oil , overcoming the technical defect of solvent and oil nonresistance of the present rubber anti-corrosive lining, filling the application blank of the corrosion prevention of the rubber lining in a solvent or oil medium, greatly expanding the application filed of the rubber anti-corrosive lining and solving the problem that the oil-resistant rubber anti-corrosive lining adheres on the surface of steel equipment.

Description

technical field [0001] The invention relates to a highly oil-resistant rubber anti-corrosion lining resistant to acid and alkali corrosion, oil and solvent and a preparation method thereof, belonging to the field of chemical anti-corrosion material manufacturing. Background technique [0002] The patent CN1139690C owned by the applicant, the name is "room temperature self-curing butyl rubber lining", and its compounding formula is: butyl rubber 100, carbon black 60-90, barium sulfate 40-80, resin 5-15, sulfur 1.5, Accelerator 1.5-2.5, processing aid 10, stearic acid 1. Anti-corrosion lining rubber for ferrous metal equipment or cement equipment. [0003] The rubber anti-corrosion linings currently on the market, such as natural rubber linings (NR), neoprene rubber linings (CR), and butyl rubber linings (IIR), in addition to the traditional high-pressure heat vulcanization production process, also appear Atmospheric hot water vulcanization, direct atmospheric steam vulcaniz...
