Abstract
The invention relates to an aqueous coating, in particular to a nanometer aqueous high-temperature-resistant metal-baking coating which can be used for decorating the surfaces of building materials and household kitchenware, such as electric irons, cookers, high-temperature lamps, ceramic products, and the like and has high temperature (600-700 DEG C) resistance, weatherability longer than 30 years and high rigidity. The preparation process comprises the following steps: mixing aqueous aluminum paste or aqueous pearlescent pigment, water and a dispersant at a low speed to prepare a semi-finished product of aqueous aluminum paste or aqueous pearlescent pigment; sequentially adding aqueous high-temperature-resistant nanometer resin, a flatting agent, a film-forming additive and a pH value regulator at a medium speed; and filtering and packaging after the semi-finished product is detected to be qualified to obtain the nanometer aqueous high-temperature-resistant metal-baking coating. The invention contains no toxic organic solvent, is pollution-free and has the advantages of high temperature resistance, weatherability longer than 30 years, high rigidity, wide suitability, and the like.
Description
【Technical field】 [0001] The invention relates to a water-based high-temperature resistant nano-coating, in particular to a surface decoration that can be widely used in electric irons, cooking utensils, high-temperature lamps and ceramic products and other household appliances and kitchen utensils and building materials. It has high temperature resistance, weather resistance for more than 30 years, high Water-based high temperature resistant nano coating with hardness and wide applicability. 【Background technique】 [0002] At present, most home appliances, kitchen utensils, and ceramic products use a large number of organic coatings and solvent-based paints. Soft, causing secondary pollution of the air, causing great harm to human health. 【Content of invention】 [0003] The invention aims at the secondary pollution generated when the paint is dried on high-temperature appliances or used, and provides a nano-water-based high-temperature-resistant metal baking paint that c...
