Abstract

The invention discloses a weather-resistant high-temperature-resistant ultra-high molecular weight polyethylene fiber composite material and a preparation method thereof. The preparation method comprises the following steps: adding acrylate rubber, a cross-linking agent, a plasticizer, an anti-aging agent and a vulcanizing agent into an open mill, and blending to obtain a matrix A; adding nitrile rubber and polyvinyl chloride into an internal mixer to be blended to obtain a matrix B; adding the matrix A and the matrix B into an open mill, uniformly mixing, adding quartz sand and dolomite, and blending; continuously adding the chopped ultra-high molecular weight polyethylene fibers for blending; and standing the blended rubber for 24-48h, and discharging sheets after remixing to obtain the weather-resistant high-temperature-resistant ultra-high molecular weight polyethylene fiber composite material. The preparation process is simple and easy to operate, the prepared weather-resistant high-temperature-resistant ultra-high molecular weight polyethylene fiber composite material improves the performance of an original material, has excellent performance such as weather resistance and high temperature resistance, the service life of the material is prolonged, and the original defects of the material are overcome.

Description

technical field [0001] The invention belongs to the technical field of composite fiber materials, and in particular relates to a weather-resistant high-temperature-resistant ultra-high molecular weight polyethylene fiber composite material and a preparation method thereof. Background technique [0002] Ultra-high molecular weight polyethylene fiber is currently the fiber with the highest specific strength and specific modulus in the world, and its molecular weight is between 1 million and 5 million. Its high specific strength and high specific modulus, the specific strength is more than ten times that of steel wire with the same cross-section, and the specific modulus is second only to super carbon fiber. Fiber density is low and can float on water. The elongation at break is low, the work at break is large, and it has a strong ability to absorb energy, so it has outstanding impact resistance and cut resistance. Anti-ultraviolet radiation, anti-neutron and γ-ray, high spec...
