Description
Technical field
The present invention relates to a kind of polyethylene fiber and manufacture method.
Background technology
Polyethylene is that chemical composition and molecular structure are the simplest, the maximum plastics variety of output, because polyethylene has good resistance to low temperature, chemical stability is good, and acid and alkali-resistance corrodes, the characteristics such as water imbibition is little have important application in Aero-Space, industry, fishery.Polyethylene fiber is mainly used in fishery at present, makes the fishing gears such as fishing net, gang rope.The fishing polyethylene fiber is that the employing high density polyethylene (HDPE) is raw material, and through melt spinning, first break draft technique is prepared into polyethylene monofilament.In order to make fishing have enough fracture strengths (more than or equal to 56cN/tex) with polyethylene fiber, must carry out abundant drawing-off to it, but because polyethylene macromolecular chain structure height is symmetrical, fully height-oriented its degree of crystallinity that makes of polyethylene macromolecular chain after drawing-off is larger, thereby cause the toughness of the polyethylene fiber of preparing relatively poor, the fishing used time shows as the knot strength not ideal enough (knot strength is lower than 42cN/tex) of fiber.For example the patent No. 03150536.8, name is called the polyethylene fiber of polyethylene monofilament high temperature high times drawing technology production because the drawing-off medium is selected ethylene glycol, make production cost increase, in addition due to excessive drawing-off make the flexibility of polyethylene fiber and knot strength relatively poor.
Summary of the invention
The purpose of this invention is to provide a kind of fishing polyethylene fibre manufacture.
Technical scheme of the present invention adopts following steps: (1) evenly extrudes preparation elastomer/active nano particle compound system by double screw extruder with elastomer and active nano mix particles; (2) compound system that makes is mixed by the double screw extruder granulation with polyethylene, make master batch; (3) will make master batch and polyethylene and antioxidant, mix lubricant makes the high density polyethylene (hdpe) fiber by melt spinning-high drafting technique; It is characterized in that described elastomer is a kind of in ethylene-octene copolymer, EP rubbers, ethylene propylene diene rubber, described elastomeric melt index is 0.5～20g/min; Described active nano particle is the nano-calcium carbonate of surface after the oleophylic modification; Described polyethylene melt index is 0.1～20g/min; Described polyethylene is the composition of high density polyethylene (HDPE) or high density polyethylene (HDPE) and ultra-high molecular weight polyethylene, and the high density polyethylene (HDPE) mean molecule quantity adopts 120,000-150,000, ultra-high molecular weight polyethylene molecular weight 800,000-4,000,000; Described high density polyethylene (HDPE) is 7:3～9:1 with the combination ratio of the composition of ultra-high molecular weight polyethylene; In described step (1), the time of staying of material in screw extruder is 2～3 minutes, and temperature is 150～250 ℃; In described step (2), the time of staying of material in screw extruder is 2～3 minutes, and temperature is 150～250 ℃; Melt spinning and high drafting technique in described step (3) are: spinning temperature is 260～350 ℃, and spinning speed is 5～50m/min, and drafting multiple is 8～12 times, and drawing temperature is 95～100 ℃.
The present invention is owing to adopting elastomer/active nano particle compound system to strengthen toughening modifying to polyethylene, the polyethylene fiber that makes through melt spinning, high drafting technique.Nano particle increases substantially the intensity of material as packing material, be used to the toughening modifying of polymeric material and elastomer has high tenacity, the transparency.The present invention adopts the collaborative toughened polyethylene fiber that strengthens of elastomer/active nano particle compound system, give full play to nano particle and elastomeric effect, (fracture strength is more than or equal to 62cN/tex to significantly improve the intensity of polyethylene fiber and toughness, knot strength is more than or equal to 46cN/tex), and have the low advantage of production cost, can reduce costs 5%-10%.
