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 polyurethane elastomer and polyvinyl chloride composite cable material that is effective against insects and ants, is prepared from the following raw materials in parts by weight (kg): thermoplastic polyurethane elastomer 60, polyvinyl chloride 35, stearic acid 0.1, benzene Calcium formate 5, mercaptan methyl tin heat stabilizer 0.8, titanate coupling agent 1310.2, epoxy soybean oil 19, hydrogenated castor oil 2, pyrethrin H2, zeolite molecular sieve 6, imidacloprid 2, hexadecyl tri Methyl ammonium chloride 0.8, appropriate amount of deionized water, γ-chloropropyl triethoxysilane 1.

[0015] The polyurethane elastomer and polyvinyl chloride composite cable material that has the effect of avoiding insects and ants 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 ...

Abstract

The invention discloses a polyurethane elastomer and polyvinyl chloride composite cable material keeping off termites and moths. The polyurethane elastomer and polyvinyl chloride composite cable material is prepared from, by weight, 60-65 parts of thermoplastic polyurethane elastomers, 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 thermal stabilizer, 0.2-0.3 part of titanate coupling agent 131, 19-20 parts of soybean oil epoxide, 2-3 parts of hydrogenated castor oil, 2-3 parts of fenvalerate, 6-7 parts of zeolite molecular sieve, 2-3 parts of imidacloprid, 0.8-1 part of cetyltrimethylammonium chloride, an appropriate amount of deionized water and 1-1.3 parts of gamma-chloropropyl triethoxy silane. The manufactured cable material has good mechanical properties, has good effects of keeping off and killing the termites and moths and can be used outdoors, damage to the cable is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a composite cable material of polyurethane elastomer and polyvinyl chloride which has the function of preventing insects and ants. 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 resistan...
