Anti-cracking antioxidant antirust epoxy finish paint and preparation method thereof

Abstract

The invention relates to an antirust paint, in particular to an anti-cracking antioxidant antirust epoxy finish paint and a preparation method thereof. The finish paint is prepared from the following raw materials in parts by weight: 40-50 parts of polybutadiene epoxy resin, 28-40 parts of polyamide resin, 10-13 parts of acrylate/C10-30 alkyl acrylate cross-linking copolymer, 1-1.5 parts of zinc diricinoleate, 20-28 parts of butyl acetate, 4-6 parts of dimethylaminoethyl methacrylate, 12-15 parts of n-butyl alcohol, 10-14 parts of calcium carbonate, 1-3 parts of dilauryl thiodipropionate, 4-5 parts of tung oil, 18-22 parts of an antirust pigment, and 2-3 parts of an auxiliary. The paint slurry in the finish paint is uniform and stable in properties, light in smell, and excellent in adhesive force, flexibility, wear resistance, impact resistance and other mechanical performances after complete curing; the paint film can keep good flexibility after long time use, and is low in possibility of cracking and oxidation; compared with the conventional epoxy antirust finish paint, the finish paint is durable, wear-resisting, capable of realizing long-standing antirust protection, and suitable for the assorted finish paint of various high-performance special antirust primer, epoxy zinc-rich paint and epoxy micaceous iron antirust paint.

Description

technical field [0001] The invention relates to an anti-rust paint, in particular to an anti-crack, anti-oxidation and anti-rust epoxy top paint and a preparation method thereof. Background technique [0002] Anti-rust paint is a kind of coating used to protect metal surfaces from the erosion of air, sea water and other substances. It is widely used in daily life. Epoxy anti-rust topcoat is a relatively common type of anti-rust paint. Polyamide resin is used as the curing agent, accompanied by different antirust pigments, so as to prepare different antirust paints, which have good adhesion and paint film strength. At present, most of the epoxy resin antirust topcoats on the market have poor weather resistance. Poor, not resistant to ultraviolet rays, easy to chalk after long-term use, not durable enough in anti-rust effect, easy to fall off the paint film and other problems, restricting the application of epoxy topcoat.
