Abstract

The invention provides an anti-oxidation material and a preparation method thereof. The anti-oxidation material can be used as a nonstick pan coating layer. The preparation method of the anti-oxidation material comprises the following steps: 1, dissolving astaxanthin in dimethyl formamide, adding poly(aryl ether nitrile ketone) to the above obtained solution, uniformly mixing poly(aryl ether nitrile ketone) and the obtained solution, reacting poly(aryl ether nitrile ketone) with the solution at 50-80DEG C for 60-120min to obtain a first reaction product; 2, adding a silane coupling agent to the first reaction product, and reacting the silane coupling agent with the first reaction product at 50-80DEG C for 60-120min to obtain a second reaction product; 3, fully and uniformly mixing methyltriethoxysilane, methyl tert-butyl ether, azodicarbonamide, diphenyldimethoxysilane and deionized water, adding the second reaction product to the obtained mixed solution, reacting the second reaction product with the mixed solution at a constant temperature of 30-50DEG C for 3-5h, carrying out normal pressure distillation at 60-90DEG C to evaporate most of solvents, reducing the pressure to -0.08MPa, slowly heating the above system to 120-160DEG C, and keeping the temperature for 30-60min to obtain a third reaction product; and 4, placing the third reaction product in a mixer, and carrying out extruding granulation to obtain the anti-oxidation material.

Description

technical field [0001] The invention relates to an anti-oxidation material and a preparation method thereof. Background technique [0002] The non-stick pan coatings currently on the market are mainly fluorine-containing resins or a mixture of ceramics and fluorine-containing resins. These coating materials will decompose at high temperatures, such as perfluorooctanoic acid, which is considered to have continuous bioaccumulation. It can stay in the human body for several years or even longer, and has a serious impact on the health of the human body. In addition, the existing non-stick pan coating is easy to fall off, not only does not have the effect of anti-sticking after falling off, but also the material that falls off is easily mixed into food and eaten by people. [0003] In addition, oil, as an important raw material in people's daily cooking, is one of the three essential nutrients for the human body, and oil oxidation is an important factor affecting food quality an...
