Abstract

The invention discloses a heat shrink tube for an automobile, and a preparation method thereof. The heat shrink tube for the automobile is characterized by comprising the following raw materials in parts by weight: 25 to 30 parts of polyethylene-vinyl acetate, 25 to 30 parts of polyethylene, 10 to 20 parts of ethylene-propylene-diene monomer (EPDM), 20 to 30 parts of decabromodiphenyl ethane, 5 to 10 parts of antimonous oxide, 0 to 1 part of an antioxidant, and 0 to 1 part of a lubricating agent. The heat shrink tube for the automobile has the following beneficial effects: the new raw materials are added in the formula and the original proportion is adjusted, so that under the condition of not changing the original physical performance, the flame-retardant level is greatly increased, and the pungent smell is eliminated.

Description

technical field [0001] The invention relates to the technical field of automobile wire harness production, in particular to a heat-shrinkable tube for automobiles and a preparation method thereof. Background technique [0002] At present, the main materials used to produce heat-shrinkable tubing include: ① olefin polymers or copolymers; ② rubber-like materials or thermoplastic elastomers styrene-butadiene-styrene block copolymer (SBS), styrene - One or more materials in the isoprene block copolymer (SIS); ③ other auxiliary materials. However, the existing heat-shrinkable tube raw materials have problems such as poor flame retardancy and pungent odor. Contents of the invention [0003] The object of the present invention is to provide a heat-shrinkable tube for automobiles and a preparation method thereof, which can greatly improve the flame retardancy level and eliminate the pungent smell. [0004] To achieve the above object, the present invention provides the following...
