Problems solved by technology

Although the thermoplastic polyurethane elastomer improves the toughness of the polyvinyl chloride material, it also reduces the modulus of the composite material at the same time, and uses dioctyl phthalate as a plasticizer, and the benzene ring structure contained in it is harmful to the human body. Potentially physiologically toxic and cause environmental pollution

Embodiment Construction

[0014] A composite cable material with synergistic effect of modified montmorillonite enzymolysis lignin, prepared from the following raw materials in parts by weight (kg): thermoplastic polyurethane elastomer 60, polyvinyl chloride 35, stearic acid 0.1, calcium benzoate 5. Mercaptan methyl tin heat stabilizer 0.8, titanate coupling agent 1310.2, epoxy soybean oil 19, phosphate ester 2, sodium montmorillonite 5, sodium laurate 0.7, enzymatic lignin 2, anhydrous Appropriate amount of ethanol, appropriate amount of deionized water.

[0015] The composite cable material with the synergistic effect of the modified montmorillonite enzymatically decomposing lignin is made by the following specific steps:

[0016] (1) Put calcium benzoate into a high-speed mixer, heat to 100°C, add stearic acid and titanate coupling agent 131, stir at 1000 rpm for 20 minutes, and discharge for use;

[0017] (2) Add polyvinyl chloride into the high-speed mixer, add mercaptan methyl tin heat stabilize...

Abstract

The invention discloses a composite cable material under synergic actions of modified montmorillonite and enzymatic hydrolysis lignin. The composite cable material is prepared from the following raw materials in parts by weight: 60-65 parts of thermoplastic polyurethane elastomer, 35-40 parts of polyvinyl chloride, 0.1-0.12 part of stearic acid, 5-6 parts of calcium benzoate, 0.8-1 part of methyl tin mercaptide heat stabilizer, 0.2-0.3 part of titanate coupling agent 131, 19-20 parts of epoxy soybean oil, 2-3 parts of phosphate, 5-6 parts of sodium-base montmorillonite 0.7-0.8 part of sodium laurate, 2-3 parts of enzymatic hydrolysis lignin, a right amount of anhydrous ethanol and a right amount of deionized water. The thermoplastic polyurethane elastomer-polyvinyl chloride composite cable material integrates the respective advantages, and has the characteristics of excellent comprehensive properties and favorable heat stability. The prepared cable can be used in a high-temperature environment, and has the advantages of longer service life and environment-friendly pollution-free raw materials; and the technique is convenient for industrial control.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a composite cable material with synergistic effect of modified montmorillonite enzymatically decomposing lignin. Background technique [0002] Polyvinyl chloride (PVC) is characterized by high withstand voltage and insulation resistance, and has properties such as flame retardancy, oil resistance, weather resistance, and chemical resistance, but its dielectric constant and dielectric loss are large, and its cold resistance is poor. Plastic has the characteristics of low price, large usage, and excellent performance in all aspects. It is mainly used in insulation, semi-conductive shielding and sheathing of various wires and cables for wires and cables below 1kV and local communication cables. Thermoplastic polyurethane elastomers have the characteristics of plastic reprocessing and rubber elasticity, and are excellent in cold resistance, abrasion resistance and antibacteri...
