Problems solved by technology

[0002] Plastic alloy is a new type of high-performance plastic material developed since the 1990s. Compared with plastics synthesized by chemically synthesized polymer resins, it has the advantages of short cycle, small investment, simple process, low cost, and high performance. Domestic plastics Alloys started relatively late, but the demand is relatively large. Imported products are expensive, and processing and maintenance are very inconvenient, which is far from meeting the needs of various industries in society for plastic alloys.

Abstract

The invention relates to a high-toughness and anticorrosive plastic alloy. The alloy consists of main components and auxiliary components, wherein the main components consist of the following components in percentage by mass: 30 to 40 percent of magnesium, 15 to 18 percent of lithium, 1 to 5 percent of cobalt, 18 to 25 percent of nickel, and 1 to 5 percent of vanadium; and the auxiliary components consist of the following components in percentage by mass: 15 to 25 percent of polypropylene, and 1 to 2 percent of lubricating agent. The high-toughness and anticorrosive plastic alloy has good anticorrosive property and high toughness.

Description

technical field [0001] The invention relates to the field of plastic alloys, in particular to a high-toughness, corrosion-resistant plastic alloy and a preparation method thereof. Background technique [0002] Plastic alloy is a new type of high-performance plastic material developed since the 1990s. Compared with plastics synthesized by chemically synthesized polymer resins, it has the advantages of short cycle, small investment, simple process, low cost, and high performance. Domestic plastics Alloys started relatively late, but the demand is relatively large. Imported products are expensive, and processing and maintenance are very inconvenient, which is far from meeting the needs of various industries in the society for plastic alloys. Contents of the invention [0003] In order to solve the above problems, the present invention provides a non-precious metal dental alloy material obtained by melting and casting of magnesium, lithium, cobalt and nickel and having a prote...
