Environment-friendly self-lubricating wearable injection-molded nylon 66 and preparing process thereof

Abstract

The invention relates to an organic polymer composite, in particular to environment-friendly self-lubricating wearable injection-molded nylon 66 and a preparing method thereof. The environment-friendly self-lubricating wearable injection-molded nylon 66 comprises the following components by weight percentage: 49.5-90 percent of nylon 66, 0.1-1.5 percent of external lubricant, 3-35 percent of silicon wearable modifier, 0.3-1.5 percent of antioxidant, 0.1-3.0 percent of heat stabilizer and 0.3-5.5 percent of other accessory ingredients. The environment-friendly self-lubricating wearable injection-molded nylon 66 has better self-lubricating performance and abrasion resistance based on original comprehensive performances of injection molded nylon 66, is convenient to produce and purchase, and adopts domestic raw and auxiliary materials and production equipment, thereby greatly reducing the production cost and material cost and improving the comprehensive competiveness of the product.

Description

technical field [0001] The invention relates to an organic polymer composite material, and more specifically relates to an environmentally friendly self-lubricating wear-resistant injection molding grade nylon 66 and a preparation method thereof. Background technique [0002] Nylon 66 is one of the most widely used engineering plastics. It is widely used to make parts of various machinery, automobiles, chemicals, electronics and electrical devices. It has a high melting point and has good physical and mechanical properties and wear resistance. Sexuality and self-lubrication, especially suitable for high-strength or wear-resistant parts, these comprehensive characteristics are not available in other plastics. 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...

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
