Abstract

The invention discloses a highly polar polyolefin material and a preparation method thereof, belonging to the technical field of materials. The material of the present invention comprises the following components in parts by weight: 70-90 parts of polyolefin, 6-20 parts of filler, 1-15 parts of polar additive, 2-10 parts of compatibilizer, and 0.5-2 parts of nano-synergist part, other additives 0.5‑2 part. And discloses the preparation method. The material of the invention has the characteristics of excellent processing fluidity, good mechanical properties, high dimensional stability, short molding cycle, good appearance of the product, and can also meet the requirements of more lightweight and thin-walled design for injection molding and other products, reducing the material cost of the product. and manufacturing cost; at the same time, the material preparation method of the present invention is easy to operate, high in production efficiency, and easy to realize industrialization.

Description

technical field [0001] The invention relates to a highly polar polyolefin material and a preparation method thereof, belonging to the technical field of materials. Background technique [0002] Polyolefin is a very important raw material for the petrochemical industry and the national industrial economy, but generally, polyolefin is a non-polar material with very low surface energy, poor compatibility with most polar substances, and is not easy to wet, adhere or adhere Poor, affect the apparent quality of the product, generally increase the surface treatment work in the later stage, but it will prolong the product process, and will also bring environmental problems. [0003] In order to improve the compatibility of polyolefins with polar substances, it is generally solved by introducing polar groups on polyolefins. Functional groups such as maleic anhydride are grafted on polyolefin molecular chains, but the problems faced by such methods are very prominent, such as: 1. Dur...

AI Technical Summary

Problems solved by technology

Functional groups such as maleic anhydride are grafted on polyolefin molecular chains, but the problems faced by such methods are very prominent, such as: 1. During the grafting reaction, severe molecular chain degradation is easy to occur, resulting in the material itself The mechanical and heat resistance properties are reduced, and at the same time, it will cause residues and toxic hazards; 2. The grafting rate of this method is limited, no more than 1%, and it is difficult to effectively improve the polarity of polyolefin itself
