Abstract

The invention discloses a high-wear-resistant and crack-resistant ceramic paint and a preparation method thereof. The high-wear-resistant and crack-resistant ceramic paint is composed of a component A as a main agent, a component B as a curing agent and a component C as a catalyst, wherein the weight ratio of the component A to the component B to the component C is equal to (2-3) to (1-2) to 0.01. The preparation method comprises the steps of mixing all the components according to a certain ratio, and curing to obtain a finished product of the paint. If being matched with silica sols with different particle sizes, the paint has the characteristics of excellent crack resistance and good wear resistance, and is convenient to construct and environmental friendly.

Description

technical field [0001] The invention relates to the technical field of ceramic coatings, in particular to a high wear-resistant and anti-cracking ceramic coating applicable to cooking utensils such as frying pans and baking pans and a preparation method thereof. Background technique [0002] At present, there are two main types of non-stick coatings commonly used in the market, one is fluorine coatings based on polytetrafluoroethylene (PTFE), such as Teflon; the other is based on silica sol and alkoxy Silane monomers are ceramic coatings prepared by sol-gel method (sol-gel). The inorganic nano-coating prepared by sol-gel technology overcomes the problems of poor temperature resistance, flame resistance and hardness of traditional organic coatings, and it has the characteristics of inorganic materials such as thermal stability, wear resistance, scratch resistance and non-combustibility. The coating of this system mainly uses water as a solvent, and there is no need to add PF...
