Description

technical field [0001] The invention relates to the technical field of heat-shrinkable sleeve materials, in particular to a corrosion-resistant heat-shrinkable sleeve material and a preparation method thereof. Background technique [0002] Heat-shrinkable sleeve, also known as heat-shrinkable protective sleeve, provides insulation protection for wires, cables and wire terminals. It has the characteristics of low-temperature shrinkage, softness, flame retardancy, insulation and corrosion resistance, etc. Anti-rust and anti-corrosion of metal pipes and rods. In order to further expand the scope of use of heat shrinkable tubing, the heat shrinkable tubing material is usually functionally modified according to the needs of the place of use, such as adding a flame retardant to enhance the flame retardant properties of the heat shrinkable tubing material, through Add thermally conductive fillers to give the heat-shrinkable sleeve material good thermal conductivity, and improve th...
