Self-drying waterborne ceramic coating and preparation method thereof

Abstract

The invention discloses a self-drying waterborne ceramic coating and a preparation method thereof. The self-drying waterborne ceramic coating is characterized by comprising a solution A and a solutionB, wherein the solution A is prepared from the following components in percentage by weight: 40-50% of silicate solution, 10-20% of powder filler, 5-15% of pigment filler, 1-10% of antirust powder, 1-5% of auxiliary and the balance of solvent; and the solution B is prepared from the following components: 20-40% of siloxane, 40-60% of silica gel solution and the balance of solvent.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a self-drying water-based ceramic coating and a preparation method thereof. Background technique [0002] At present, there are generally three types of ceramic coatings. The first is general zinc-rich coatings. This type of coating has low temperature resistance and loses its protective effect when exposed to high temperatures. Its hardness is soft, its protection ability is poor, and its appearance is not good. Dark color, the second is PTFE fluorocarbon coating, this kind of coating is not environmentally friendly, once the coating is heated, it will produce a toxic gas, change color quickly, and is not safe, it will produce open flames and smoke when exposed to high temperatures of 300 ° C, which will harm the environment and human body The damage is great, and it is not energy-saving. The sintering temperature must be above 380°C, and it takes more than 30 minutes, and the s...

[0002] At present, there are generally three types of ceramic coatings. The first is general zinc-rich coatings. This type of coating has low temperature resistance and loses its protective effect when exposed to high temperatures. Dark color, the second is PTFE fluorocarbon coating, this kind of coating is not environmentally friendly, once the coating is heated, it will produce a poisonous gas, which changes color quickly and is not safe. It will produce open flames and smoke when exposed to high temperatures of 300°C, which will harm the environment and human body. The damage is great, and it is not energy-saving. The sintering temperature must be above 380 ° C, and it takes more than 30 minutes, and the self-cleaning property is poor, and it is not anti-fouling. It is not environmentally friendly, pollutes the environment, is easy to oxidize, and is not weather-resistant, acid-resistant, salt-resistant, and energy-saving. It is usually expensive to maintain, and it is not temperature-resistant and flame-retardant. Open flames, dense smoke, easy to change color, crack and peel off when the temperature is above 50°C, and the surface hardness is low, easy to scratch
