Silicon rubber shrinkable tube and preparation method thereof

Abstract

The invention discloses a silicon rubber shrinkable tube and a preparation method thereof. In order to solve the problems that the conventional shrinkable tube has low high-temperature resistance, oil resistance and solvent resistance and cannot meet the requirements on high oil resistance and solvent resistance in automobiles, high-speed trains, military project, space flight and other industries, the invention provides a silicon rubber shrinkable tube, which mainly comprises the materials of silicon rubber, shrinkable resin, a reinforcing agent, a cross-linking agent, silicone oil and optional zinc stearate. Meanwhile, the invention also provides a method for preparing the shrinkable tube from the materials. The provided silicon rubber shrinkable tube has high stability and high heat resistance and cold resistance, and can be applied to electric and electronic industrial places with higher requirements on heat resistance, cold resistance and insulation property.

Description

technical field [0001] The invention relates to a heat-shrinkable tube, in particular to a silicone rubber heat-shrinkable tube 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. Although the existing heat-shrinkable tubes have good flame retardancy and environmental protection performance, they are relatively poor in temperature resistance, oil resistance and solvent resistance, and cannot adapt to high oil resistance and solvent resistance in automobiles, high-speed trains, military and aerospace industries. requirements. Contents of the invention [0003] In order to overcome the problem that the existing heat-shrinkable tubes have relatively poor ...
