High-toughness corrosion-resistant material

[0014] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention. , Not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0015] This embodiment is a high-toughness and corrosion-resistant material, which is made of the following parts by weight of raw materials: 30 parts by weight of zircon, 35 parts by kaolin, 10 parts by water-soluble urea-formaldehyde resin, and hydroxyethyl fiber 15 parts of element, 5 parts of silicon carbide, 5 parts of titanium dioxide, 8 parts of composite admixture, 6 parts of aluminum nitride, 8 parts of calcium carbonate, 8 parts of toughening agent, 8 parts of cosolvent; the composite admixture is sodium sulfate, At least one of triethanolamine and organosilicon; the toughening agent is at least one of aluminum oxide, zirconium oxide, and titanium carbide; the co-solvent is sodium carbonate, sodium nitrate, sodium fluorosilicate, and ethylene oxide At least one of amine salts.

[0016] The high-toughness and corrosion-resistant material of the present invention has good flexural strength and fracture toughness, excellent impact resistance, good thermal stability and corrosion resistance, and its flexural strength can reach 1510-1608Mpa and fracture toughness can reach 16.1-17.2Mpa ·M1/2, the present invention enhances the compatibility of various materials by adding hydroxyethyl cellulose, and further improves the tear resistance and resilience performance of the finished product. The present invention is suitable for use in cable fillers and is environmentally friendly, Corrosion resistance and other advantages.

[0017] The addition of hydroxyethyl cellulose to the raw material of the present invention can enhance the toughness of the material. The introduction of fibers not only improves the toughness of the ceramic material, but more importantly, it fundamentally changes the fracture behavior of the ceramic material from the original brittle fracture. Become a non-brittle fracture.
