Corrosion-proof easily-demoulded nylon-66 plastic

Abstract

The invention relates to an organic polymer composite, in particular to corrosion-proof easily-demoulded nylon-66 plastic, which comprises, by weight, 66:65-85% of polyamide, 2-32% of powdered graphite, 0.3-2.7% of antioxidant, 0.5-3.2% of heat stabilizer, 0.4-2.9% of coupling agent, 0.1-3.2% of high-molecular-weight silicon oil and 0.5-5.5% of activated carbon. The corrosion-proof easily-demoulded nylon-66 plastic has the advantages that self-lubricating performance and corrosion-proof performance of graphite are excellent, automatic demoulding can be achieved during injection molding or extruding of finished products, demoulding agent is not needed, and prepared plastic is not easy to corrode due to the corrosion-proof graphite.

Description

technical field [0001] The invention relates to an organic polymer composite material, more specifically, relates to a corrosion-resistant and easy-release nylon 66 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. The total output value of enterprises above designated size in the plastic products industry ranks ...

Problems solved by technology

[0003] At present, the plastics provided on the market generally have the characteristics of low corrosion resistance and low mold release performance. Although some improvements have been made on the market, it is still not easy to release the mold during the manufacturing process, and there are still certain difficulties. In addition , the anti-corrosion effect of the plastic made is not obvious, and it will still corrode due to long-term use or contact with some acid-base items, so that the life of the plastic will also be shortened, and there will be great pollution to the environment after the plastic is discarded. The constant replacement of plastic will also cause certain financial problems for the enterprise
