Problems solved by technology

[0002] With the improvement of people's living standards, all kinds of household appliances involved in life are constantly being updated to meet the various requirements of consumers. Among them, the existence of ovens in every household is closely related to our lives. The ovens need Powder coatings have relatively high requirements, but most of the powder coatings used in ovens in the prior art have the following problems: 1) Poor high temperature resistance, frequent peeling off and bubbles after surface coating, and relatively large gloss changes, 2) The powder coatings used in ovens in the prior art all contain solvents, which cause great environmental pollution and certain potential safety hazards; therefore, a new technical solution is urgently needed to solve the above technical problems
