Problems solved by technology

The traditional process uses electrostatic powder spraying and high-pollution environment painting to prevent the chemical change, damage and corrosion of the galvanized layer, but the sprayed film and paint layer are easy to fall off after the above process is used for a long time. Not good, poor corrosion resistance

Abstract

The invention provides a yellow-gray quick-drying anti-corrosive paint for galvanized stainless pipe fittings. The yellow-gray quick-drying anti-corrosive paint is prepared from the following components in percentage by weight: 35%-45% of acrylic resin, 10%-15% of modified resin, 10%-12% of titanium dioxide, 3%-5% of medium chrome yellow, 0.2%-0.3% of high-pigment carbon black, 0.5%-1% of dispersing agents, 0.2%-0.5% of flatting agents, 1%-1.5% of adhesive force auxiliary agents, 0.5%-1% of anti-corrosion agents, 10%-15% of butyl acetate and 15%-20% of dimethyl benzene. The invention also provides a preparation method of the yellow-gray quick-drying anti-corrosive paint for the galvanized stainless pipe fittings. 10%-15% by weight of the modified resin, the adhesive force auxiliary agents and the anti-corrosion agents are additionally used for the formula of the yellow-gray quick-drying anti-corrosive paint, so that a composition formed by the components and other components is increased in adhesive force and improved in anti-corrosive property; the galvanized stainless pipe fittings show the yellow-gray and are attractive in appearance after being coated with the yellow-gray quick-drying anti-corrosive paint.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a yellow-gray quick-drying anti-corrosion coating for galvanized stainless steel steel pipe fittings and a preparation method thereof. Background technique [0002] Galvanized stainless steel pipe is a welded steel pipe with a hot-dip or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of the steel pipe and prolong its service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, and oil heaters and condensation pipes for chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, trestle piles, and support pipes for mine tunnels, etc. [0003] For the galvanized layer, zinc is a relatively ac...
