Problems solved by technology

Softened or melted PTFE coating When the bubbles in boiling water or oil escape and burst quickly, under the impact force, the PTFE coating produces a blank area, and water and oil can penetrate the PTFE coating Directly coated with the pan, and infiltrated in the form of liquid or gas at high temperature and heated between the PTFE coating and the pan body, so that the bonding force of the PTFE coating on the outer edge of the blank area will decrease, and the blank area Expand, and finally make the PTFE coating soften and fall off in flakes, reducing the service life of the pot

Abstract

The invention belongs to the technical field of anti-adhesion, and particularly relates to anti-adhesion gel and a preparation method thereof. The gel capable of being applied to the anti-adhesion field is prepared from hydrogenated camellia oil, hydrotalcite, modified silicon carbide and other raw materials, and the gel can be applied to metal cookware, food-grade hard plastic molds, medical-grade anti-adhesion gauze and other anti-adhesion fields. The anti-adhesion gel has the advantages of simple process, no toxic or harmful effect on human bodies, prolongation of the service life of the non-stick coating at high temperature, and improvement of the wear resistance, the good heat conduction, the corrosion resistance and the impact resistance of the prepared coating, and no shedding caused by heating.

Description

technical field [0001] The invention belongs to the technical field of anti-adhesion, and in particular relates to an anti-adhesion gel and a preparation method thereof. Background technique [0002] In industrial production and daily life, how to prevent adhesion is a frequently encountered problem, such as release agents used in industrial manufacturing, anti-adhesion isolation films used in the medical field, non-stick pans used in daily life, etc. [0003] For non-stick pans, the common ones with the best non-stick performance are polytetrafluoroethylene coating and ceramic coating. At present, the polytetrafluoroethylene coating is coated with water-based polytetrafluoroethylene non-stick soil material or will The PTFE powder coating is sprayed on the metal surface and then cured after high temperature baking. Due to the limitation of the melting point of polytetrafluoroethylene, when the non-stick pan is misoperated and dry-fired, the polytetrafluoroethylene coating w...
