PVC/NBR cold-resistant oil-resistant flame retardant thermoplastic elastomer material for new energy automobile charging pile cable and preparation method thereof

Abstract

The invention discloses a PVC / NBR cold-resistant oil-resistant flame retardant thermoplastic elastomer material for a new energy automobile charging pile cable and a preparation method thereof. The elastomer material is prepared from, by weight, 100 parts of polyvinyl chloride resin, 20-40 parts of powder butyronitrile, 30-40 parts of plasticizer A, 20-30 parts of plasticizer B, 20-30 parts of plasticizer C, 5-10 parts of stabilizer, 6-12 parts of flame retardant A, 6-12 parts of flame retardant B, 6-12 parts of flame retardant C, 0.5-1.5 parts of lubricant, 1-2 parts of antioxidant A, 1-2 parts of antioxidant B and 40-70 parts of inorganic filler. The elastomer material is high in mechanical property, good in hydrolysis resistance, strong in oil resistant property and cold resistant property and good in dispersion uniformity and low-temperature flexibility, and therefore the cable is not damaged in multiple times of tow dragging; the PVC / NBR cold-resistant oil-resistant flame retardant thermoplastic elastomer material is good in processing performance, free of particles and smooth in extrusion surface, low in cost, easy to prepare and operate, suitable for occasions on which the elastomer material needs to be frequently bent and scraped at low temperature with oil.

Description

technical field [0001] The invention relates to a PVC / NBR cold-resistant, oil-resistant, flame-retardant thermoplastic elastomer material for new energy vehicle charging pile cables and a preparation method thereof, belonging to the field of elastomer materials for charging pile cables. Background technique [0002] In the prior art, the materials used for charging pile cables of new energy vehicles are mostly TPE materials. Due to its high price, the use of TPU is limited to a certain extent. Although TPE has a certain wear resistance, it is difficult to pass the oil resistance. , Poor flame retardancy, easy to absorb moisture and difficult to process. More and more manufacturers of new energy charging piles hope to obtain a new energy material that not only has good wear resistance and flame resistance, but also satisfies good oil resistance, is easy to process and has excellent cost performance. [0003] The invention provides a PVC / NBR cold-resistant, oil-resistant, and...
