Abstract

The invention provides an ultra-high molecular weight polyethylene resin composition. The ultra-high molecular weight polyethylene resin composition is characterized in that 100 parts of ultra-high molecular weight polyethylene resin, 0.001 to 0.5 part of antioxidant and 0 to 0.6 part of mineral filler are included according to parts by weight, wherein the molecular weight of the ultra-high molecular weight polyethylene resin is between 2,000 thousand and 5,000 thousand, the average particle diameter ranges from 80 mum to 300 mum, the particle size distributional width is less than 3.0, the tensile breaking stress is higher than 25 MPa, and the tensile breaking strain is higher than 200 percent. The ultra-high molecular weight polyethylene resin composition overcomes the defects that fibers are easily broken and the fiber property is unstable during the spinning process of the present ultra-high molecular weight polyethylene fiber; the ultra-high molecular weight polyethylene resin has better spinning effect; and the fiber has the characteristics of high strength, high modulus, stable property, and the like.

Description

technical field [0001] The invention relates to an ultra-high molecular weight polyethylene (UHMWPE) resin. The resin is suitable for continuous production of high-strength, high-modulus ultra-high molecular weight polyethylene fibers. Background technique [0002] With the development of ultra-high molecular weight polyethylene industry, ultra-high molecular weight polyethylene fiber has also been developed faster and faster. It is the third generation of high-performance fiber after carbon fiber and aramid fiber. It has low density and high modulus. , UV resistance, wear resistance, impact resistance, high strength and other outstanding properties, it has the highest cost performance among the three existing fiber materials. The fiber has the characteristics of both military and civilian uses, and is widely used in special ropes, fishing nets, sports equipment, various light soft bulletproof vests, bulletproof helmets, riot shields, explosion-proof devices and other prote...
