Environment-friendly regenerated low-temperature-resistant reinforced wear-resistant polyketone material and preparation method thereof

Abstract

The invention discloses an environment-friendly regenerated low-temperature-resistant reinforced wear-resistant polyketone material and a preparation method thereof. The environment-friendly regenerated low-temperature-resistant reinforced wear-resistant polyketone material is prepared from 20-30 parts of raw material polyketone, 20-30 parts of regenerated polyketone, 5-15 parts of a wear-resistant agent, 20-40 parts of a filling reinforcing agent, 0.2-0.6 part of an antioxidant and 0.3-0.6 part of a nucleating agent, the invention also discloses a preparation method of the environment-friendly regenerated low-temperature-resistant reinforced wear-resistant polyketone material. Aiming at the technical problems that an existing recycled material is poor in recycling performance, a polyketone material modification process is complicated, inconvenient to operate, not environment-friendly enough and the like, regenerated polyketone and a new polyketone material are selected to be mixed and proportioned, polytetrafluoroethylene is used as a wear-resistant agent, glass fiber is used as a filling enhancer, and an antioxidant and a nucleating agent are used as auxiliary materials; the modified polyketone material with good fluidity, low cost, excellent mechanical properties and wear resistance, low temperature resistance and simple processing formability is prepared, the blank of the material in the domestic modification industry is filled, the modification method is simple, and the environmental protection property is good.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an environment-friendly regenerated low-temperature-resistant reinforced wear-resistant polyketone material and a preparation method thereof. Background technique [0002] Polyketone (PK) is a new green material that was successfully polymerized and mass-produced by South Korea's Hyosung Group for 10 years. The material is a polymer obtained by absorbing carbon monoxide in the air and then copolymerizing with ethylene and propylene. The material has very few branches on the molecular chain and no hydrophilic or lipophilic groups, so its chemical resistance is extremely excellent. With the policy of carbon peaking at home and abroad and a series of energy saving and emission reduction measures, the use of renewable polyketone (PK) materials for modification and reuse not only maintains excellent performance but also achieves the purpose of energy saving and emission red...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide an environmentally friendly regenerated low temperature resistant reinforced wear-resistant polyketone material and its preparation method, in order to solve the poor recovery performance of the existing recycled materials and the complex and insufficient modification process of the polyketone material. Environmental protection, the modification of the environmentally friendly regenerated low-temperature-resistant enhanced wear-resistant polyketone material belongs to domestic blanks and other technical issues. The present invention selects polyketone, regenerated polyketone and other additives to obtain a product with good fluidity, low cost, and high mechanical properties. And the modified polyketone material with excellent wear resistance and simple processing formability fills the gap in the domestic modification industry of this material, and at the same time the modification method is simple and environmentally friendly
