Problems solved by technology

[0002] It is known that polypropylene (pp) is a semi-crystalline thermoplastic, which has the advantages of high impact resistance, strong mechanical properties, resistance to various organic solvents, and acid and alkali corrosion resistance. The disadvantage is that it is brittle and aging at low temperatures. , not wear-resistant
Polyethylene (PE) thermoplastic resin has excellent low temperature resistance and chemical stability, especially the high tensile strength of linear low density polyethylene, good puncture resistance, tear resistance and ability to withstand most Acid and alkali erosion, excellent electrical insulation performance, the disadvantage is poor shaping, it should not be used alone in plastic braiding

Embodiment Construction

[0009] Embodiment, formula is by polypropylene 80%-75%, linear low density polyethylene 20%-25%, diatomaceous earth 7%-10%, antioxidant 0.04-0.08%, antiultraviolet agent 0.07-0.1%, silane The coupling agent is 0.05%-0.1%, and the production process is completed step by step according to the steps of melting, extrusion, water cooling, wire separation, drawing, shaping, and winding.

[0010] When using the present invention, the diatomite needs to be pretreated. The method is to put the diatomite into a mixer and then pour the diluted silane coupling agent into it for stirring. After fully mixing and evenly dispersing, take it out and complete.

[0011] When using the present invention, the melting and extruding molds are divided into melting zone 170°C-180°C, plasticizing zone 200°C-210°C, kneading zone 205°C-215°C and heat preservation The temperature range is 160°C-170°C.

[0012] When using the present invention, the setting temperature should be kept at 85%°C-95%°C.

Abstract

The invention discloses a novel high-strength anti-ultraviolet plastic-woven flat filament production process. The novel high-strength anti-ultraviolet plastic-woven flat filament production process comprises a formula and the production process, wherein the formula is composed of 80 percent to 75 percent of polypropylene, 20 percent to 25 percent of linear low density polyethylene, 7 percent to 10 percent of diatomite, 0.04 percent to 0.08 percent of antioxidant, 0.07 percent to 0.1 percent of anti-ultraviolet agent, and 0.05 to 0.1 percent of silane coupling agent. The production process comprises the following steps: melting, extrusion demoulding, water cooling, filament division, drawing, shaping, spindle rolling and the like. The formula of the production process disclosed by the invention is simple, the cost is low, and the assembly is easy; the production process is consistent and is easy to operate and control.

Description

technical field [0001] The invention relates to the application field of plastic weaving, in particular to a novel high-strength and anti-ultraviolet plastic braided flat wire production process. Background technique [0002] It is known that polypropylene (pp) is a semi-crystalline thermoplastic, which has the advantages of high impact resistance, strong mechanical properties, resistance to various organic solvents, and acid and alkali corrosion resistance. The disadvantage is that it is brittle and aging at low temperatures. , Not wear-resistant. Polyethylene (PE) thermoplastic resin has excellent low temperature resistance and chemical stability, especially the high tensile strength of linear low density polyethylene, good puncture resistance, tear resistance and ability to withstand most Corrosion by acid and alkali, excellent electrical insulation performance, but poor shaping, it should not be used alone in plastic braiding. Contents of the invention [0003] The p...
