Problems solved by technology

However, cleaning agents are easy to corrode the surface of kitchen appliances, causing corrosion of materials and causing permanent and irreparable damage to products
[0006] 3) Existing kitchen appliances require users to use strong alkaline cleaners with hard cleaning products such as steel wool, and clean them under the action of a large cleaning force. Although such methods can clean kitchen appliances to a certain extent However, the strong alkalinity and the large scratching force during cleaning often cause scratches and corrosion on the surface of the material, which is very easy to damage the surface of the electrical product material, affect the appearance of the product, and even damage the surface of the product. Affect the performance; moreover,

Abstract

The invention relates to a hydrophilic coating easy to clean and a preparing method of the hydrophilic coating. The hydrophilic coating easy to clean comprises, by mass, 25%-44% of silica sol, 15%-40% of aluminum sol, 10%-25% of titanium sol, 5%-9% of an alkali metal silicate aqueous solution, 3%-6% of hydrophilic fumed silica, 0.5%-1% of assistant and 10%-20% of solvent. The preparing method includes the steps that the silica sol, the aluminum sol, the titanium sol, the alkali metal silicate aqueous solution, the hydrophilic fumed silica, the assistant and the solvent are mixed together according to the ratio to prepare the hydrophilic coating easy to clean. The hydrophilic coating easy to clean has the easily-cleaned performance, acid resistance, base resistance, scraping resistance and other performances.

Description

technical field [0001] The invention relates to an easy-to-clean paint, in particular to a hydrophilic easy-to-clean paint and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of living standards, people's requirements for materials are getting higher and higher, and the easy-to-clean performance of materials is also getting higher and higher. Existing kitchen electrical materials are difficult to meet consumers’ requirements for easy-to-clean performance. Kitchen electrical products are exposed to oily fumes, acid-base substances, and various seasonings for a long time and at high frequencies, which makes the contactable surface easily stained with oil. Due to the adhesion of oil and materials The strong knot force makes it difficult to remove the oil from the surface, which brings great troubles to product users. It is a difficult pain point for consumers to use kitchen appliances for a long time. [0003]...
