Embodiment 1

[0034] First, the base material consisting of 60 parts of linear low density polyethylene and 15 parts of ethylene / vinyl acetate copolymer was thoroughly mixed in a mixer for 3 minutes, and 20 parts of epoxy resin coated ammonium polyphosphate, 12 parts of pentaerythritol, melamine urea 10 parts of acid salts, 60 parts of aluminum hydroxide and 25 parts of zinc borate composite inorganic flame retardant, 3 parts of lubricating oil, 8 parts of maleic anhydride grafted EVA were added in the mixer and stirred for 5 minutes. Distribute the remaining components (1.5 parts of triallyl tripolyisocyanate, 0.3 parts of ethylene glycol lauric acid amide, 10100.5 parts of antioxidant, 0.1 part of auxiliary antioxidant DLTP, 0.2 part of oxalic acid dihydrazide) and then stir Mix for 5 minutes. Knead at 200°C for 1.5 hours, and pulverize, and the speed of the kneader is 840 r / min. The above-mentioned fully mixed mixed components are extruded through an extruder to obtain pellets, which ar...

Embodiment 2

[0036]First, the base material composed of 75 parts of linear low density polyethylene and 20 parts of ethylene / vinyl acetate copolymer was thoroughly mixed in a mixer for 3 minutes, and 25 parts of ammonium polyphosphate, 15 parts of pentaerythritol and melamine urea were coated with epoxy resin. 12 parts of acid salts, 55 parts of aluminum hydroxide and 20 parts of zinc borate composite inorganic flame retardant, 2 parts of lubricating oil, 7.5 parts of maleic anhydride grafted EVA were added in the mixer and stirred for 5 minutes, and the mixed group was mixed. The remaining components (0.5 part of triallyl isocyanate, 0.3 part of ethylene glycol lauric acid amide, 10100.4 parts of antioxidant, 0.2 part of oxalic acid dihydrazide) were distributed and mixed for 8 minutes. Knead at 195° C. for 1.5 hours, and pulverize, and the kneader rotates at 700 r / min. The above-mentioned fully mixed mixed components are extruded through an extruder to obtain pellets, which are then coat...

Embodiment 3

[0038] First, the base material consisting of 70 parts of linear low-density polyethylene and 15 parts of ethylene / vinyl acetate copolymer was thoroughly mixed in a mixer for 3 minutes, and 25 parts of ammonium polyphosphate, 10 parts of pentaerythritol, melamine urea were coated with epoxy resin 8 parts of acid salts, 52 parts of aluminum hydroxide and 21 parts of zinc borate composite inorganic flame retardant, 1.5 parts of lubricating oil, 7.8 parts of maleic anhydride grafted EVA were added in the mixer and stirred for 5 minutes. Divide the remaining components (1 part of triallyl isocyanate, 0.5 part of ethylene glycol lauric acid amide, 0.3 part of antioxidant 1010, 0.2 part of auxiliary antioxidant DLTP, 0.2 part of oxalic acid dihydrazide) Stir to mix for 5 minutes. Knead at 190°C for 1.5 hours, and pulverize, and the kneader rotates at 900 r / min. The above-mentioned fully mixed mixed components are extruded through an extruder to obtain pellets, which are then coated...

Abstract

The present invention discloses low-smoke halogen-free flame-retardant antistatic aging-resistant wire and cable material and its preparation method. The wire and cable material comprises (by weight parts) polyethylene 60-80, ethylene-vinyl acetate copolymer 10-20, coated ammonium polyphosphate 20-40, pentaerythritol 10-20, a nitrogen flame retardant 8-15, a composite inorganic flame retardant 50-90, a lubricant 2-5, a compatilizer 5-10, a crosslinking additive 0-3, an antistatic agent 0.2-0.8, an antiager 0.3-0.6, an auxiliary antioxidant 0-0.3, and a metal passivator 0-0.5. Compared with the prior art, the inventive wire and cable material has good high-temperature resistance, high strength, high elongation, high flame retardancy, antistatic property, aging resistance and harmlessness, and is widely applicable for electric power, building, communication and manufacture fields.

Description

Technical field [0001] The invention belongs to the technical field of polymer material modification, and specifically relates to a low-smoke, halogen-free, flame-retardant, anti-static and aging-resistant wire and cable material and a preparation method thereof. Background technique [0002] The wire and cable industry is the second largest industry in my country after the automobile industry, with product variety satisfaction rate and domestic market share exceeding 90%. Worldwide, my country's total output value of wires and cables has surpassed that of the United States, becoming the world's largest wire and cable producer. With the rapid development of my country's wire and cable industry, the number of new companies continues to rise, and the overall technical level of the industry has been greatly improved. At present, polyvinyl chloride wire and cable materials are commonly used in China. They have high temperature resistance, good strength, high elongation, and goo...
