Fireproof smoke-free wear-resisting ceramic coating

Abstract

The invention discloses a fireproof smoke-free wear-resisting ceramic coating, which is prepared from, by mass, 400 parts of silicon solution, 400 parts of silicane, 100 parts of silicon carbide, 80 parts of electric smelting white corundum powder, 200 parts of titanium dioxide, and 0.1 part of silicon oil, 0.1 part of neutralizer, and 1 part of enhancer. A method for preparing the fireproof smoke-free wear-resisting ceramic coating, which mainly comprises the steps of taking above raw materials at ratio, dispersing the silicon solution and titanium dioxide until the fineness is 10 miu m below; then adding silicon carbide, electric smelting white corundum powder, silicane, silicon oil, and enhancer components, and stirring for 6-7 hours. The fireproof smoke-free wear-resisting ceramic coating applies high-intensity and high-hardness main materials, and also applies the hard-hardness nano-scale silicon carbide and corundum material, so as to further enhance the wear resistance of the coating; according to yb / t5201-1993 standard, the compression strength under the room temperature is more than 170 MPa; according to GB / T 3001-2000 standard, the fracture strength under the room temperature is more than 55 MPa; the Moh's hardness reaches level 9; moreover, the ceramic coating is waterproof, combustion-free, and smoke-free, and is applicable to subway, shopping mall, and other public places; therefore, the ceramic coating is safe and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-hardness ceramic coating applied to ceramics. Background technique [0002] The ceramic coating itself has high hardness, but poor toughness. During use, it is easy to be bumped, impacted, scratched, etc., causing poor adhesion, cracking or falling off; The main technical scheme of water-based ceramic coating is: A, B, and C are mixed according to the mass ratio: 666:333:1, of which: A component: based on the percentage of the total mass of the ceramic coating: silicon Sol 26-30%, antimony solution 13-15%, inorganic high temperature resistant pigment 5-13% and silicon dioxide 8-12%; B component: based on the percentage of the total mass of ceramic coating: silane 30-34% , wetting agent 0.4-0.6%, leveling agent 0.4-0.6%; C component: based on the percentage of the total mass of the ceramic coating: catalyst 0.1%, the hardness of the ceramic made by it can reach 8H, but, a...

Problems solved by technology

Traditional solvent-based coatings mostly use organic solvents such as toluene, xylene, and butyl acetate as diluents. The manufacturing and construction process causes huge pollution to the environment due to the large amount of organic solvents discharged.

Traditional solvent-based coating products are used in closed environments such as subway stations and stations. Once a fire occurs, a large amount of toxic and dense smoke will be generated, which will often increase the difficulty of evacuating passengers and fire fighting and disaster relief.

In addition, during the operation of rail transit, the mobility of personnel is high, the probability of bumping and scratching on decorative materials is also high, and the possibility of surface contamination also increases
