Abstract

The invention relates to the field of high polymer materials, and particularly discloses a high-fluidity ultra-high molecular weight polyethylene wear-resistant plate and a preparation method thereof. The high-fluidity ultra-high molecular weight polyethylene wear-resistant plate comprises the following substances in parts by weight: 20-50 parts of an ultra-high molecular weight polyethylene diaphragm plate, 18-30 parts of polyamide, 3-5 parts of paraffin oil and 2-3 parts of a functional additive. After the ultra-high molecular weight polyethylene diaphragm plate is recycled, polyamide is adopted to replace an oily material adopted in a traditional diaphragm plate, so that on one hand, the flowing property of the ultra-high molecular weight polyethylene material is effectively improved, and the ultra-high molecular weight polyethylene material is convenient to process and extrude; on the other hand, due to the good crystallization property and wear resistance of polyethylene, polyethylene is added into the ultra-high molecular weight polyethylene material, so that the wear resistance of the composite material can be improved, and the defects of poor processability and wear resistance of the recycled ultra-high molecular weight polyethylene diaphragm plate after no oily substance is added are effectively overcome.

Description

technical field [0001] The application relates to the field of polymer materials, more specifically, it relates to a high-fluidity ultra-high molecular weight polyethylene wear-resistant plate and a preparation method thereof. Background technique [0002] The molecular weight of ultra-high molecular weight polyethylene is generally large, and its relative molecular mass is generally greater than 1.5 million. It is precisely because of the extremely high relative molecular mass of ultra-high molecular weight polyethylene that UHMWPE has many advantages that ordinary polyethylene does not have. It is one of the most comprehensive properties among all engineering plastics. However, ultra-high molecular weight polyethylene also has shortcomings. The main disadvantage is that the processing fluidity is extremely poor. Therefore, improving the flow properties of ultra-high molecular weight polyethylene materials is the key to its practical adjustment. [0003] In the existing pr...
