    Core tip: an anti-corrosion coating for cutting tools, which includes basic coating and silicone resin, and the volume ratio of basic coating and silicone resin is 1:0.5-4; the volume percentage of components of the basic coating is: pH regulator is 5-25%, functional catalyst is 0.001-0.7%, siloxane composition is residual, functional catalyst is catalyst containing carbon powder Catalyst: the solid-liquid ratio of carbon powder and catalyst is 1:5-15; the volume percentage of the catalyst is 20-60% zirconate; acetylacetone; 1-15%; isopropanol and isopropanol Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings: The utility model relates to an anticorrosive coating for cutting tools, which comprises a basic coating and an organic silicon resin, and the volume ratio of the basic coating and the organic silicon resin is 1:0.5-4; the volume percentage of the components of the basic coating is: the pH regulator is 5-25%, the functional catalyst is 0.001-0.7%, the siloxane composition is the residual, the functional catalyst is the catalyst containing carbon powder; wherein, The solid-liquid ratio of the carbon powder to the catalyst is 1:5-15; the volume percentage of the components of the catalyst is 20-60% of zirconate, 1-15% of acetylacetone, 7-25% of diphenyldimethoxysiloxane, 7-15% of methyltrimethoxysiloxane, and 7-15% of γ - glycidyl ether oxypropyl trimethoxane 1-5% for silanes, 7-10% for phenyl trimethoxysiloxanes, and the residual for propylene glycol methyl ether The invention forms a space cross-linking structure through zirconate, acetylacetone and isopropanol, which is beneficial to control the mild reaction, and can control the reaction rate more than the catalyst only using zirconate The preparation method of carbon powder includes the following steps: (1) carbonization: apricot shell, walnut shell and coffee slag are used as raw materials, the mass ratio of the three materials is 1:2:1, they are dried at 150-180 ℃ for 1-2 hours, then calcined at 300-400 ℃ for 1-2 hours, and then calcined at 600-700 ℃ for 1-2 hours to obtain multifunctional carbon powder; (2) Micronization: the multifunctional carbon powder is micronized and grinded into the multifunctional carbon powder of 30-200 nanometer level; the preparation method of the catalyst is as follows: the temperature in the reactor is controlled at 40 ℃, isopropanol is added first, zirconate is added while stirring, stirring slowly for 5 minutes until the mixture is uniform; under the stirring state, acetylacetone is added slowly to the mixed mixture in the reactor In the mixed solution, the reaction is carried out at 40 ℃ for 1 hour after dripping, and the material is cooled out; the preparation method of the functional catalyst is: adding carbon powder into the catalyst, stirring continuously, and the reaction time is 1-3 hours Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
