High-efficiency anti-rusting epoxy finishing paint loaded with silicon dioxide nano spheres and preparation method of high-efficiency anti-rusting epoxy finishing paint

Abstract

The invention relates to anti-rusting paint, and in particular relates to high-efficiency anti-rusting epoxy finishing paint loaded with silicon dioxide nano spheres and a preparation method of the high-efficiency anti-rusting epoxy finishing paint. The paint is prepared from the following raw materials in parts by weight: 40-50 parts of epoxy resin, 26-32 parts of polyamide resin, 4-6 parts of poly omega-caprolactone diol, 3-4 parts of silicon dioxide nano spheres, 1-2 pars of nano copper oxide, 3-5 parts of fischer tropsch, 1-2 parts of polyphosphazene, 6-8 parts of dimethoxymethane, 1-2 parts of a silane coupling agent, 15-18 parts of magnesium silicate, 18-22 parts of n-butyl acetate, 18-22 parts of anti-rusting pigment and 2-3 parts of an additive. According to the paint, the modified silicon dioxide nano spheres and nano copper oxide are loaded on epoxy resinite, so that the hardness and the toughness of a paint membrane are improved, in addition, by adopting the preparation method of the paint, the raw materials are relatively sufficiently combined, and the paint is excellent in mechanical property after being completely cured, is durable and long-lasting when being compared with conventional epoxy anti-rusting finishing paint and is applicable to various high-performance special anti-rusting primers, epoxy zinc-rich paint and matting finishing paint of epoxy micaceous iron rust preventing paint.

Description

technical field [0001] The invention relates to an antirust paint, in particular to a high-efficiency antirust epoxy finish loaded with silica nanospheres 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.
