Problems solved by technology

[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 powder after long-term use, not durable enough for anti-rust effect, easy to fall off the paint film and other problems, restricting the application of epoxy topcoat

Embodiment

[0012] The paint of this embodiment is made of the following raw materials in parts by weight: epoxy resin 50, polyamide resin 28, ferrocene 4, castor oil polyoxyethylene ether 3, polyoxyalkylene diamine 3, dimethylol butyric acid 2. Nano titanium dioxide 10, hydrogenated rosin 6, butyl acetate 25, n-butanol 15, antirust pigment 25, additive 3.

[0013] The auxiliary agent is made of the following raw materials in parts by weight: vinyl tertiary carbonate 12, titanium acetylacetonate 2, multi-walled carbon nanotubes 5, zinc hydroxystannate 2, and hexafluoroisopropanol 6. The preparation method is as follows: first Mix ethylene tert-carbonate and hexafluoroisopropanol, after mixing thoroughly, add other remaining materials, ultrasonically disperse for 30 minutes and then grind for 50 minutes, the obtained slurry is the solubilizing and modifying additive.

Abstract

The invention relates to an antirust paint, particularly an ultraviolet-aging-resistant antirust epoxy finish paint and a preparation method thereof. The paint is prepared from the following raw materials in parts by weight: 40-50 parts of epoxy resin, 22-28 parts of polyamide resin, 3-4 parts of ferrocene, 1-3 parts of castor oil polyethenoxy ether, 2-3 parts of polyoxy alkylidene diamine, 1-2 parts of dihydroxy methylbutyric acid, 8-10 parts of nano titanium dioxide, 4-6 parts of hydrogenated rosin, 20-25 parts of butyl acetate, 12-15 parts of n-butanol, 18-25 parts of antirust pigment and 2-3 parts of assistant. The paint raw materials contain the modified ferrocene and nano titanium dioxide powder, so that the combining capacity with the resin slurry can be enhanced, and the ultraviolet aging resistance of the epoxy resin is greatly improved. The raw materials of the epoxy finish paint are combined more sufficiently; the epoxy finish paint has excellent mechanical properties after being completely cured; and the epoxy finish paint has higher outdoor service performance and higher durability, and is suitable to be used as a matched finish paint for various high-performance special-type antirust primers, epoxy zinc-rich paints and epoxy micaceous iron antirust paints.

Description

technical field [0001] The invention relates to an antirust paint, in particular to an ultraviolet aging-resistant antirust epoxy finish 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.
