Core-shell structure coating easy to clean and preparing method and application thereof

Abstract

The invention relates to the field of coating easy to clean and discloses a preparing method of core-shell structure coating easy to clean. The preparing method is characterized by comprising the steps that firstly, nano particles and alcohol solvent are mixed evenly under stirring, a coupling agent is added under stirring, and an alcoholic solution of a nano particle microballoon sphere structure is obtained; secondly, organic solvent is added to the alcoholic solution of the nano particle microballoon sphere structure, an initiator is added for the first time under stirring at the inert atmosphere and at the temperature from 15 DEG C to 50 DEG C, the temperature is increased to 60 DEG C to 105 DEG C, silicon-containing monomers, fluorine-containing monomers, ester monomers and a dispersing agent are added, the initiator is added for the second time, a reaction is conducted, and the mixture is cooled to the indoor temperature after reaction is completed. The invention further discloses the core-shell structure coating easy to clean and application of the coating in kitchen appliances, and the coating is prepared through the method. The coating is easy to clean, resistant to acid and alkali and resistant to scraping, and can be widely applied to the kitchen appliances.

Description

technical field [0001] The present invention relates to an easy-to-clean coating, in particular to a method for preparing an easy-to-clean coating with a core-shell structure, the easy-to-clean coating with a core-shell structure prepared by the method and the application of the easy-to-clean coating with a core-shell structure in kitchen appliances . 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 requirements for the easy-to-clean performance of materials are also getting higher and higher, especially for long-term and high-frequency contact with various oils, seasonings, acids and alkalis. The materials used for kitchen appliances, people's requirements for the easy-to-clean performance of materials used in such appliances are increasing day by day. [0003] The current kitchen appliance materials can already meet the basic requirements of...

AI Technical Summary

Problems solved by technology

[0003] The current kitchen appliance materials can already meet the basic requirements of electrical appliances for materials. However, the current technology is difficult to meet the increasingly strong requirements of users for easy cleaning.

Range hoods, stoves, microwave ovens and other household appliances commonly used in the kitchen have long-term and high-frequency contact with oil fumes, acid-base substances, and various seasonings, resulting in oil stains on the outer surface and inner tank. Most of the materials in contact are metal materials or metal materials with powder spraying treatment on the surface. The surface energy of these materials is relatively large, resulting in a strong adhesion between oil and materials, and it is difficult to remove oil from the surface of kitchen appliances. It is a pain point for consumers to use kitchen appliances for a long time.

[0004] At present, the users of kitchen appliances mainly adopt the method of cleaning such oil stains by using strong alkaline cleaners combined with hard cleaning products such as steel wool, and cleaning under the action of a relatively large cleaning force. To a certain extent, it can clean the material surface of kitchen appliances, but the strong alkalinity and the large scratching force during cleaning often cause scratches and corrosion on the surface of the material, which affects the appearance of the product and even affects the performance. It brings permanent and irreparable damage to the product; moreover, this traditional method is difficult to clean, takes a long time, and cannot meet the user's convenience and easy cleaning requirements
