Antibacterial wear-resistant ceramic paint for non-stick pan and preparation method thereof

Abstract

The invention discloses an antibacterial wear-resistant ceramic paint for a non-stick pan and a preparation method thereof. The antibacterial wear-resistant ceramic paint comprises the following raw materials by weight: 20 to 40 parts of organosilane, 10 to 30 parts of manganese-alumina spinel powder, 10 to 30 parts of modification quartz powder, 5 to 25 parts of mica powder, 4 to 12 parts of polyacrylate, 5 to 25 parts of a filling material, 4 to 8 parts of an adhesive, 1 to 5 parts of a leveling agent, 1 to 5 parts of a dispersing agent, 1 to 5 parts of a titanate coupling agent and 20 to 40 parts of ethanol. Quartz powder is weighed and then preheated and dried in a drying box at 85 to 150 DEG C for 1 to 2 h; and the modified quartz powder is prepared by adding ammonia water and a coupling agent and then carrying out mixing under stirring, filtering, vacuum drying and the like. The preparation method comprises the following steps: uniformly mixing a part of the raw materials including organosilane, mica powder and the like, then adding ethanol, the filling material and the adhesive, carrying out uniform mixing under stirring, finally adding the rest raw materials, and carrying out uniform mixing under stirring. The ceramic paint for the non-stick pan has good mechanical properties, high-temperature resistance, wear resistance and an antibacterial function, is simple to prepare and poses no toxicity and harm to human beings and environment.

Description

technical field [0001] The invention belongs to the field of non-stick outer layer coatings, and in particular relates to an antibacterial and wear-resistant ceramic coating for non-stick pans and a preparation method thereof. Background technique [0002] With the improvement of living standards, people have higher and higher performance requirements for the surface coating of non-stick pans. They not only need to be resistant to high temperature and acid and alkali corrosion during work, but also bear different degrees of wear and tear. Some of the currently used The coatings of polytetrafluoroethylene, polyperfluoroethylene propylene and various fluorine-containing copolymers have insufficient surface wear resistance and adhesion, which will cause the coating to be quickly worn and peeled off and lose its protective effect on the substrate. , thereby affecting the quality and life of the non-stick pan. In addition, during the cooking process, the peeled non-stick coating ...

[0002] With the improvement of living standards, people have higher and higher performance requirements for the surface coating of non-stick pans. They not only need to be resistant to high temperature and acid and alkali corrosion during work, but also bear different degrees of wear and tear. Some of the currently used The coatings of polytetrafluoroethylene, polyperfluoroethylene propylene and various fluorine-containing copolymers have insufficient surface wear resistance and adhesion, which will cause the coating to be quickly worn and peeled off and lose its protective effect on the substrate. , thereby affecting the quality and life of the non-stick pan. In addition, during the cooking process, the peeled non-stick coating is mixed with food or washed by water, which will not only cause health hazards to the human body, but also cause damage to the natural environment. , does not meet the standards of green environmental protection
