Abstract

The invention relates to a method for strengthening enamelware through carbon fiber. The method comprises base material pretreatment, enamel ground coat coating, carbon fiber containing enamel porcelain glaze manufacturing, enamel porcelain glaze coating, cover glaze coating and other processes. According to the method, high-strength and low-cost carbon fiber strengthened enamel-based materials are used, and crack deflection happens to an enamel base body in the fracture process; when the fiber is fractured or pulled out, impact energy is absorbed, and accordingly, the strength and tenacity ofenamel materials are enhanced; and meanwhile, due to adding of carbon fiber, high-temperature resisting performance and corrosion resisting performance of the enamel materials cannot be influenced, and the material integrally has good comprehensive performance.

Description

technical field [0001] The invention relates to the field of enamel products, in particular to a method for reinforcing enamel products with carbon fibers. Background technique [0002] Enamel is a metal coated with one or more layers of inorganic vitreous materials on its surface. After high temperature, the surface coating is melted, so that complex physical and chemical changes occur, and the metal and its surface coating are firmly combined to form a kind of enamel. Composite material, which has both the mechanical strength and easy processing characteristics of metal materials and the corrosion resistance, wear resistance, heat resistance, non-toxicity and rich decorative effects of inorganic glass materials. [0003] Although enamel has excellent performance, it also has the shortcomings of being brittle and not high in impact strength. How to overcome these shortcomings, the industry has also proposed many methods. to increase strength, etc. However, due to the effe...
