preparation example Construction

[0025]The preparation method of the insulating layer and the sheath material of the charging pile connecting cable comprises the following steps:

[0026] S1: Add polyvinyl chloride resin, ethylene vinyl acetate copolymer, hydrogenated nitrile rubber, acrylate rubber, and cross-linking agent into the mixer and stir evenly, then add accelerator, anti-aging agent, and plasticizer, and heat up to 70- Mix at 80°C for 6-10 minutes to obtain mixed material A; the stirring speed of the mixer is 200-500r / min;

[0027] S2: Add anti-scorch agent, stabilizer, polymer compatibilizer, coupling agent, naphthenic oil, polychlorotrifluoroethylene, polyethylene wax to the mixed material A in step S1, then heat up to 90-110°C, mix 6-8min, to obtain the mixed material B;

[0028] S3: Put the mixed material B in step S2 into a twin-screw extruder to granulate at a processing temperature of 150-180° C. to obtain insulation layer and sheath material for cables.

Abstract

The invention discloses an insulated layer and sheath material of a charging pile connecting cable, and belongs to the technical field of preparation. The insulated layer and sheath material of the charging pile connecting cable is prepared from the following raw materials: polyvinyl chloride resin, ethylene vinyl acetate copolymer, hydrogenated butadiene-acrylonitrile rubber, acrylate rubber, a cross-linking agent, a flame retardant, a scorch retarder, an accelerant, an anti-oxidant, an anti-ageing agent, a plasticizer, a stabilizer, a high molecular weight compatibilizer, a coupling agent, naphthenic oil, polytrifluorochloroethylene, and polyethylene wax. Tensile strength, elongation at break and electrical resistivity of the cable insulated layer and sheath material are improved througha reinforcing system which is prepared from naphthenic oil, polytrifluorochloroethylene and polyethylene wax, and reduces thermal deformation.

Description

technical field [0001] The invention belongs to the technical field of cable preparation, and in particular relates to an insulating layer and a sheath material of a charging pile connection cable and a preparation method thereof. Background technique [0002] At present, the existing electric vehicle charging pile connecting cable adopts a circular structure. During the charging process of the electric vehicle, the connecting cable needs to move back and forth between the vehicle and the charging pile. Since the connecting cable is exposed to the atmosphere for a long time, such a long time In use, it is inevitable that the cables will be squeezed and worn by external forces, which will affect the service life of the cables. The material is not soft enough. After the electric vehicle is charged, the cable can only be slowly retracted into the charging pile under the action of external force. When charging is required, the charging gun and the cable must be pulled out slowly...
