Abstract

The invention provides an anti-oxidizing paint for metal and wood. The anti-oxidizing paint is prepared from the following raw materials by mass fraction: 90 to 100 parts of polyurethane resin PC-2550, 5 to 10 parts of silicon carbide, 38 to 50 parts of zinc oxide whiskers, 0.2 to 0.8 part of coupling reagent KH792, 10 to 14 parts of titanium dioxide, 9 to 10 parts of zinc isoocatanoate, 5 to 10 parts of styrene maleic anhydride oligomer, 5 to 10 parts of butylcellosolve, 10 to 12 parts of diethoxymethane, and 5 to 10 parts of n-butyl alcohol, wherein the styrene maleic anhydride oligomer is SMA-1000, SMA-2000 or SMA-3000. The anti-oxidizing paint is high in ageing-resistant performance, and has resistance to artificial aging as well as resistance to a sodium hydroxide solution at a mass concentration of 10%; the resistance to artificial aging is unchanged during testing for 1000 hours, and the resistance to the sodium hydroxide solution at the mass concentration of 10% is remained during testing for 300 hours, therefore, the anti-oxidizing paint is widely used for protecting surfaces of both metal and wood.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an anti-oxidation paint for metal wood. Background technique [0002] Whiskers are generally referred to as whiskers of metals and their oxides, carbides, boride nitrides, and inorganic salts. Zinc oxide whiskers have attracted much attention because of their unique three-dimensional four-needle structure; silicon carbide is a It is an inorganic non-metallic material with high temperature resistance, high strength, good wear resistance, acid and alkali resistance, high hardness and good chemical stability. The addition of silicon carbide can greatly improve the flexural strength and wear resistance of the product, and when the particles When there is less intermatrix, the gap between particles is also smaller, so the structure is compact, the mechanical strength is higher, and the wear resistance is also better. Although there are reports of zinc oxide whiskers and silicon carbide as rei...
