Problems solved by technology

Although it has good non-stick properties, its use temperature cannot be too high, and its wear resistance is poor, so that the non-stick coating can only withstand about 30,000 times of wear under standard wear test conditions ( CMA2005 American Kitchenware Association standard), resulting in the actual service life of the non-stick pan coating is less than one year (under the normal daily use conditions of the family), resulting in high-frequency replacement of non-stick pans, resulting in waste of resources and the environment pollution

Abstract

The invention discloses a high-temperature wear resistant nonstick coating layer material and a preparation method thereof. The high-temperature wear resistant nonstick coating layer material comprises 80-99wt% of Teflon and 1-20wt% of metal oxide. A nonstick coating layer is produced from the high-temperature wear resistant nonstick coating layer material through a present nonstick coating layer coating technology, and a result of the wear resistance test of the nonstick coating layer shows that the bearable friction frequency can reach 90000 (test standard: CMA2005 Kitchenware Association Standard, and the qualified friction frequency is 30000).

Description

technical field [0001] The invention relates to a composite material, in particular to a high-temperature wear-resistant non-stick coating material and a preparation method thereof. Background technique [0002] The non-stick pan is to treat the surface of the inner cavity of the pan to form a non-stick layer, so that the surface of the non-stick layer is not easy to adhere to food, oil, etc., and it is easy to clean. [0003] The surface of the inner cavity of common non-stick pans uses a non-stick coating, and the most commonly used non-stick coating is Teflon coating. [0004] Teflon coating is a fluorine coating with polytetrafluoroethylene as the base resin. The English name is Teflon. Because of the pronunciation, it is usually called Teflon, Teflon, Teflon, Teflon, etc. . Teflon coating combines heat resistance, chemical inertness, excellent insulation stability and low friction, and has comprehensive advantages that other coatings cannot compete with. Its applicati...
