Embodiment Construction

[0040] The invention adopts organic silicon-modified ultra-high molecular weight polyethylene blending material or ternary blending material composed of ultra-high molecular weight polyethylene, organic silicon and liquid crystal macromolecule as raw materials.

[0041] Ultra-high molecular weight polyethylene blends, using silicone as a modifier for ultra-high molecular weight polyethylene to form blends, its components include ultra-high molecular weight polyethylene 85-97%, organic silicon 3-15%, anti-oxidation Agent 0.2 to 2%.

[0042] The ultra-high molecular weight polyethylene ternary blend is blended by the following components in weight percentage: ultra-high molecular weight polyethylene 88-94%, organic silicon 3-7%, liquid crystal polymer 2-5%, stearic acid Calcium 0.2-2%, antioxidant 0.1-1%.

[0043] The antioxidant used is a phenolic antioxidant, and the phenolic antioxidant is specifically selected from antioxidant 1010 or B215.

[0044] Such as figure 1 Shown...

Abstract

The invention discloses a method for producing polythene fiber with high strength and high modulus by melting fiber drawing and a device thereof. The method includes steps as follows: blend composition of polythene with super high molecular weight and three element blend composition of polythene with super high molecular weight are used as raw material, the raw material is spout fibre adobe after melted through a screw extruder, the fibre adobe is preset drafted after cooling, then low power drafted after once heating, then high power drafted after twice heating, finally is processed heat processing for obtaining polythene fiber with high strength and high modulus. The screw extruder, a cooling mechanism, a drafting machine processing preset drafting, an once heating mechanism, a low power drafting machine, a twice heating mechanism, a high power drafting machine, a heat processing mechanism, a winding reeling machine are arranged in the device orderly. The invention provides a producing method with simple technique, short producing flow, low cost and no pollution aiming at problem that UHMWPE melting spout fibre process has difficult to spin, and provides a device with compact equipment and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a method for producing high-strength and high-modulus polyethylene yarns by melt drawing. The polyethylene yarn produced by this method can be widely used in many fields such as mining, building materials, ropes, etc., such as cables, marine engineering cables, climbing ropes, fishing nets, rowing boats, sailing boats, bowstrings, ski skis, mine safety nets, various Screens, reinforced impact-resistant containers, etc., can also be used as reinforcement materials in the construction industry, and replace glass fibers, etc. Background technique [0002] Ultra-high molecular weight polyethylene (abbreviation: UHMWPE) is a kind of thermoplastic engineering plastic with excellent comprehensive properties. Its production process and molecular shape are similar to high-density polyethylene. It uses Ziegler catalyst to form branched very There are few linear molecular chains, t...
