Problems solved by technology

[0005] The object of the present invention is to provide a kind of high-hardness corrosion-resistant plastic material and its preparation method, to improve the defects of the current common preparation methods. The present invention adds silicon nitride powder, nano-titanium powder, corrosion-resistant agent, and nitrogen to the plastic material. Silicon oxide is a structural ceramic material with high hardness. In this material, nitrogen atoms and silicon atoms are combined with each other by strong covalent bonds, so that plastic materials have good hardness. Titanium is an inorganic metal material, and its own molecules The pores between them are small and have good hardness. The mixed use of nano-titanium powder and silicon nitride powder further improves the hardness of the plastic material; the anti-corrosion agent generates a polymer containing silicon-oxygen bonds during the preparation process. During the preparation process, the silicon-oxygen bond will form a protective film on the surface of the plastic to prevent corrosive substances from entering the interior of the plastic molecule. At the same time, the substance is a polymer, which greatly increases the density of the plastic material and further prevents corrosive substances from entering the interior of the plastic molecule. Epoxy resin reacts with methacrylic acid to produce a vinyl resin. The double bonds at both ends of the molecular chain of the resin are extremely active, which can be cured quickly and quickly gain strength in use, forming a polymer with high corrosion resistance, thereby improving the plastic's resistance. Corrosive, titanium and oxygen have a great affinity, in the air or in oxygen-containing media, a layer of dense, strong adhesion, inert oxide film is formed to protect plastics from corrosion
