Abstract

The invention discloses anti-rust iron oxide red epoxy primer for a rusty steel tube. The primer comprises the components in parts by mass as follows: 65-72 parts of modified epoxy resin, 22-25 pars of epoxy iron oxide red, 0.08-0.1 part of a rust conversion agent, 0.12-0.14 part of polyethylene wax, 12-15 parts of mica powder and 22-24 parts of butyl alcohol. The primer dries naturally to form a film at the room temperature within 5-6 h; the raw materials are easy to obtain, simple to produce and low in cost; the adhesive force is high and can reach grade 1, the anti-rust time is long, and the adhesive force is still intact after the rusty steel tube is coated with the primer and placed in the open for 6-8 months, so that an anti-rust effect is realized; the primer is good in matching performance and can be matched with acrylic polyurethane enamel; and the butyl alcohol is used as a diluent, so that the construction environment is improved, and the environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the field of antirust materials, in particular to an iron red epoxy antirust primer for rusty steel pipes. Background technique [0002] Anti-rust primer is generally used as a primer for base treatment. It can form a hydrophobic film on the metal surface. It is suitable for all iron-containing materials. It mainly plays an anti-rust role. It has excellent anti-rust function and can completely replace anti-rust. Rust oil and grease mainly include iron red antirust primer, epoxy antirust primer, red lead antirust primer and alkyd antirust primer. Iron red epoxy anti-rust primer is used as anti-corrosion primer for steel structures, heavy machinery, electric equipment, chemical equipment, mining machinery, ships, etc. It has good anti-corrosion performance and durability, and has excellent adhesion and impact resistance , Oil resistance, organic solvent resistance, water resistance and salt water resistance. With the developmen...
