Problems solved by technology

[0002] Bromine is a highly irritating and toxic liquid, and it also has a great corrosive effect. Manufacturers have nothing to do with it to corrode equipment and pipelines. They can only let it corrode, which reduces the service life and increases the economy of the enterprise. burden, and also affects the economic benefits of the enterprise
[0003] In the prior art, chlorosulfonated polyethylene anti-corrosion coatings are often used for anti-corrosion treatment of equipment and pipelines. This coating has serious deficiencies in performance indicators such as quick-drying and corrosion resistance. For example, chlorosulfonated polyethylene anti-corrosion coatings The effective time on equipment and pipelines is only three months, after which it will gradually foam and peel off, losing its anti-corrosion effect

Abstract

The invention discloses a bromine corrosion prevention painting, which comprises the following parts: 48-55% dimethylbenzene, 45-50% 120# petrol, 6-8% DOP, 5-6% petrol resin, 6-10% butyl rubber and fitful dye. The preparing method comprises the following steps: putting dimethylbenzene and 120# petrol in the autoclave; blending 20min to mix evenly; adding DOP, petrol resin and butyl rubber; modifying with the speed at 2400-3000r/min for 2h; adding dye to stir at 3600-4000r/min; cutting at high speed to obtain the product with fineness at 60um; displaying aging-proof property and strong adhesion force.

Description

1. Technical field [0001] The invention relates to a protective paint for bromine corrosion-resistant equipment and pipelines, in particular to a bromine-resistant paint. 2. Background technology [0002] Bromine is a highly irritating and toxic liquid, and it also has a great corrosive effect. Manufacturers have nothing to do with it to corrode equipment and pipelines. They can only let it corrode, which reduces the service life and increases the economy of the enterprise. The burden also affects the economic benefits of enterprises. [0003] In the prior art, chlorosulfonated polyethylene anti-corrosion coatings are often used for anti-corrosion treatment of equipment and pipelines. This coating has serious deficiencies in performance indicators such as quick-drying and corrosion resistance. For example, chlorosulfonated polyethylene anti-corrosion coatings The effective time on equipment and pipelines is only three months, after which it will gradually foam and peel off,...
