[0038] These components add up to a total of 1000 kg.

[0039] The particle size of the alumina in the water-dispersed nano-scale alumina can be selected to be 20 nanometers.

[0040] The pigment therein may be iron oxide black. The anti-oxidation coating obtained in this way has a metallic black color.

[0041] The filler therein can be optional silicon dioxide whiskers. The whiskers have strong dispersibility, which helps to achieve the purpose of uniform mixing in the paint. On the other hand, because of the strength of the whiskers themselves, it is beneficial to strengthen the cohesion of the...

Abstract

The invention provides high-temperature resistance oil product oxidization resistance paint and a preparation method thereof, which belong to the field of functional paint particularly applied to the aspect of oil product oxidation resistance under the condition of high temperature. Major ingredients of the paint comprise water-dispersible nanometer aluminum oxide, pigment, filling materials, potassium titanate whiskers, nanometer silver grains and one or two kinds of materials in methyltrimethoxysilane and methyl triethoxysilane. A coating layer prepared by the invention has the quality of the enamel surface, has advantages of fire resistance, high temperature resistance, high rigidity, high compactness and good weather resistance, and is completely harmless to human bodies. In addition, the invention can be used for effectively slowing down the oil product oxidation process. The edible oil can still maintain the nutritive and health quality through being placed in a high-temperature environment for a long time. The service life of the industrial oil can be prolonged.

Description

technical field [0001] The invention belongs to the field of functional coatings, and is particularly applied to the oxidation resistance of oil products under high temperature conditions. Background technique [0002] Various oil materials are widely used in industrial and agricultural production and daily life. From the perspective of edibility, it is divided into two types: edible oil and non-edible oil. Both of them may cause serious oxidation under high temperature environment. [0003] For example, when edible oil is used in an ordinary pot, the oil will react with oxygen in the air at high temperature to form peroxides, or form high polymers through dimers, resulting in an increase in the viscosity of the oil; In cooking oil with high concentration, a large number of fine and unbreakable air bubbles will be produced, and harmful cyclic polymers will be formed in the process. At the same time, the increase of oil viscosity will greatly reduce the heat conduction effi...
