Problems solved by technology

Many of these bellows need to be in contact with seawater for a long time, and often have to withstand high wind speed, strong ultraviolet radiation, high salt spray, and brine immersion, so that a thick layer of crystalline salt will condense on the surface of the bellows, corroding the bellows, and waste. Manpower to do regular cleaning, even need to replace the bellows

Abstract

The invention discloses a method for forming a salt-spray resistant coating on a surface of a nonmetallic corrugated pipe. The salt-spray resistant coating is prepared from the following raw materials in parts by weight: 300-360 parts of butadiene styrene rubber, 70-80 parts of ethylene propylene terpolymer rubber, 30-40 parts of acrylic acid, 15-25 parts of sodium stearate, 60-70 parts of paraffin, 20-40 parts of diphenyl silicon glycol, 8-15 parts of benzoyl peroxide, 10-15 parts of petroleum ether, 35-40 parts of paraffin oil, and 15 -25 parts of lubricating oil. The method disclosed by the invention can achieve formation of a protective layer on the surface of a nonmetallic corrugated pipe, which is capable of protecting the corrugated pipe from direct ultraviolet irradiation and seawater erosion. Crystalline salt cannot be coagulated easily on the surface of the protective layer, and the crystalline salt can quickly fall off after being formed on the surface of the protective layer rather than being continuously deposited. Thus, the service life of the nonmetallic corrugated pipe is greatly prolonged, and regular cleaning of the corrugated pipe is avoided, thus saving labor.

Description

technical field [0001] The invention relates to the field of corrugated pipe manufacturing, more precisely, it relates to a method for forming an anti-salt spray coating on the surface of a non-metallic corrugated pipe. Background technique [0002] Bellows are also widely used on ocean exploration ships or oil drilling platforms, most of which are non-metallic bellows, mainly made of plastic or synthetic materials. Many of these bellows need to be in contact with seawater for a long time, and often have to withstand high wind speed, strong ultraviolet radiation, high salt spray, and brine immersion, so that a thick layer of crystalline salt will condense on the surface of the bellows, corroding the bellows, and waste. Manpower to do regular cleaning, even need to replace the bellows. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a method for forming an anti-salt spray coating on the surf...
