Problems solved by technology

However, limited by its molecular structure, nylon 6 is very easy to absorb water. After absorbing water, the size of the material will become larger, the strength will be lower, and the resistivity will be lower.
Therefore, nylon 6 cannot be used in fields with high temperature and high humidity and high dimensional accuracy requirements
In addition, caprolactam, the monomer used in the production of nylon 6, has a certain degree of toxicity, and it can also decompose toxic nitrogen oxides when heated.

Abstract

The invention belongs to the technical field of high polymer materials, and discloses a high-impact wear-resistant glass fiber reinforced POK-HDPE composite material and a preparation method thereof.The high-impact-resistance wear-resistant glass fiber reinforced POK-HDPE composite material is prepared from polyketone resin, high-density polyethylene resin, a compatilizer, a wear-resistant agent,chopped glass fibers, peroxide, maleic anhydride, an antioxidant and a lubricant. The POK-HDPE composite material prepared by the invention has the advantages of high normal-temperature / low-temperature impact strength, low water absorption, good wear resistance and the like, and can be widely applied to parts with severe condition requirements such as high-temperature high-humidity wear resistance, normal-temperature / low-temperature impact resistance, wear resistance and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-impact and wear-resistant glass fiber reinforced POK-HDPE composite material and a preparation method thereof. Background technique [0002] Nylon 6 (PA6) has the characteristics of wear resistance, high strength and strong polarity, and is widely used in electronic appliances, automobiles, home appliances and other industries. However, limited by its molecular structure, nylon 6 is very easy to absorb water. After absorbing water, the size of the material will become larger, the strength will be lower, and the resistivity will be lower. Therefore, nylon 6 cannot be used in fields with high temperature and high humidity and high dimensional accuracy requirements. In addition, caprolactam, the monomer used in the production of nylon 6, has a certain degree of toxicity, and it can also decompose toxic nitrogen oxides when heated. The production of nylon 6 will ca...
