Rapid prototyping plastic

Abstract

The invention relates to an organic polymer composite material, in particular to rapid prototyping plastic. The plastic comprises the following components in percentage by weight: 56-95.5 percent of nylon 66, 2.5-15 percent of molybdenum bisulfide, 0.3-3.5 percent of antioxidant, 0.1-4.2 percent of heat stabilizer, 0.1-2.9 percent of coupling agent, 0.1-3.0 percent of silicon oil with high molecular weight, 0.5-5.5 percent of activated carbon and 0.3-5.5 percent of emulsifying agent. According to the plastic disclosed by the invention, several agents with a certain proportion are added, so that the prototyping period of the plastic is shortened while certain physical performance of the plastic is ensured and the production efficiency can be improved to a great degree.

Description

technical field [0001] The present invention relates to an organic polymer composite material, more specifically, relates to a rapid prototyping plastic. Background technique [0002] After long-term struggle and opening up to the world, China's plastics industry has formed a relatively complete industrial system and has become a basic material industry that keeps pace with steel, cement, and wood. As a new type of material, its application fields have far exceeded the above three. Since the entry of this material into the 21st century, China's plastics industry has made remarkable achievements and achieved a historic leap. As one of the pillar industries of the light industry, the plastics industry has maintained a growth rate of more than 10% in recent years. While maintaining a relatively fast development speed, the economic benefits have also improved. [0003] Nylon 66 is one of the most widely used engineering plastics. It is widely used to make parts of various machi...

Problems solved by technology

However, at present, social technology is developing rapidly, changing with each passing day, and new products and new inventions are pouring out in large numbers. For parts that can effectively and greatly reduce the friction coefficient and the raw materials themselves have strong wear resistance, the many advantages of ordinary nylon 66 make designers very happy. Favored, but the above shortcomings are very troublesome

The raw materials with the above functions currently available on the market are either expensive such as nylon 12, or are added with expensive additive materials such as polytetrafluoroethylene, which also leads to high material costs. In this way, relatively high raw materials are required. Lower raw material and production costs

[0004] There are also nylon 66 products with faster molding in the market now, but the effect is not very obvious, which slows down the production speed, and the physical and mechanical properties are not very high.
