Embodiment 1

[0024] Antioxidant coating of the present invention and preparation method thereof are as follows: weigh 64.1 parts by weight of sodium water glass and add it into 200 parts by weight of water to prepare a solution. When heating to 60°C while stirring, add 10 parts by weight of clay, 20 parts by weight part of dextrin, continuously stirred for 0.5 hours, and the resulting suspension was the binder. Weigh 50 parts by weight of boron nitride, 150 parts by weight of activated carbon, and 30 parts by weight of silicon carbide, and add the prepared binder into a ball mill tank and use a planetary ball mill for ball milling. The ball-to-material ratio is 4:1, the rotating speed is 400 rpm, and the ball milling time is 10 hours. The obtained coating is a gray-black slurry with uniform mixing and good fluidity. Using the NDJ-8S digital viscometer, the viscosity of the paint is tested at a speed of 12 rpm, the test temperature is 18°C, and the test viscosity value is 14.5MPa·S. Add 1...

Abstract

The invention discloses a sliding plate antioxidation paint and a preparation method thereof. The sliding plate antioxidation paint is prepared by the following raw materials in weight percent: 10-70% of antioxidation function additive, 15-80% of binding agent and 5-20% of diluent. The preparation method comprises the following steps: mixing antioxidation function additive and binding agent, and grinding when the ratio of ball to material is (4-1):1, rotating speed is 200-800r / min, and ball-milling time is 5-40h; adding diluent with content in weight percent being 5-20% into the ball-milled paint, and mixing uniformly to obtain a finished product. The inventive paint is gray black and pasty, can be brushed by common technique, and the thickness of coating is adjustable in large range. The preparation method of the antioxidation paint provided in the invention has available raw materials, simple technique and preparation, low cost, and easy scale production; and the obtained paint has outstanding antioxidation and self-lubricating performances at high temperature.

Description

technical field [0001] The invention relates to an anti-oxidation coating and a preparation method of the anti-oxidation coating, belonging to the field of advanced functional materials. Background technique [0002] There are roughly three anti-oxidation treatment methods for carbon-containing refractory materials, namely impregnated oxidation inhibitor method, adding antioxidant method and surface coating method. The impregnation method to inhibit the oxidation reaction generally relies on isolating the active points on the surface of the carbon material or forming a glassy covering layer to prevent oxygen diffusion, or forming a stable salt with impurities, thus losing the catalytic effect on carbon oxidation, but it is generally limited to oxidation below 1000 °C protection. There are many studies on adding Al, Mg, SiC and other antioxidant fine powders to carbon-containing refractory materials to prevent carbon oxidation, but this method can only slow down the oxidatio...
