High-temperature-resistant plating-resisting coating and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant plating-resisting coating and a preparation method thereof. The plating-resisting coating comprises the raw materials in parts by weight as follows: 40-80 parts of high-temperature-resistant silicone resin, 5-10 parts of acrylic resin, 10-35 parts of mica powder, 10-15 parts of copper chromite black and 10-20 parts of silicon dioxide. The method comprises the steps as follows: the high-temperature-resistant silicone resin, the mica powder and the copper chromite black are uniformly mixed and dispersed under the condition of 200-1500 r / min, so that a mixture is obtained; the silicon dioxide is added to the mixture, and the mixture is fully dispersed for 2-5 h; and sedimentation is performed for about 1-3 h, so that the high-temperature-resistant plating-resisting coating is obtained. According to the high-temperature-resistant plating-resisting coating, the technical requirement indexes that a plating layer is perfectly protected and is not corroded by a high-temperature plating solution and the like in an environment of 300-1000 DEG C are met; and the adhesive force of the product is high, tedious processes such as primer coating and the like are not required, the paint coating process is simple, and the cost is greatly saved.

Description

technical field [0001] The invention relates to a plating resist coating, in particular to a high temperature resistant plating resist coating, and also relates to a preparation method of the high temperature resistant plating resist coating. Background technique [0002] In the steel plate processing technology, the finished steel plate needs to be hot-dipped on the rough steel surface to improve the corrosion resistance, wear resistance, oxidation resistance and other properties of the steel. [0003] However, when hot-dip plating is performed on the surface of some precision electrical metal steel materials, large-scale chemical industry, mechanical equipment, and various high-temperature equipment that cannot be baked and dried, it is often necessary to perform hot-dip plating in designated areas, while hot-dip plating is not required outside designated areas. , or cannot be hot plated. And how to ensure that the steel surface outside the plating area is not hot-dipped ...

Problems solved by technology

However, the traditional method of filling resin coating not only has disadvantages such as cumbersome process and inaccurate filling area, but also melts and decomposes at high temperature, contaminates the coating, and even damages the steel

[0004] If the traditional resist plating process is used, simply using ordinary resin as the protective medium, not only has the disadvantages of cumbersome process, inaccurate filling area, etc., but also melts and decomposes at high temperature, pollutes the coating, and even damages the steel
