Abstract

The invention discloses a high-quality PVC (polyvinyl chloride) heat-shrinkable sleeve. The high-quality PVC heat-shrinkable sleeve comprises, by weight, 56-66 parts of PVC resin, 25-35 parts of acrylonitrile-butadiene-styrene copolymers, 2-5 parts of diatomaceous earth composite urea, 3-7 parts of diphenylethanedione oxide, 3-6 parts of graphite-modified polyurethane elastomers, 3-6 parts of nanometer aluminum oxide, 2-4 parts of nanometer carbon fibers, 2-4 parts of polyester fibers, 2-5 parts of toughening agents, 2-6 parts of stabilizers, 3-8 parts of poly-silicon borane, 0.2-0.8 part of lithium oxide, 2-3 parts of compatilizer, 2-4 parts of flame retardants, 2-4 parts of antioxidants and 2-5 parts of dispersing agents. The high-quality PVC heat-shrinkable sleeve has the advantages that the PVC resin is used as a main material and is matched with the acrylonitrile-butadiene-styrene copolymers and diversified additives, and accordingly the high-quality PVC heat-shrinkable sleeve isexcellent in heat resistance, heat-shrinkable performance, impact resistance, corrosion resistance and aging resistance.

Description

technical field [0001] The invention relates to a heat-shrinkable sleeve, in particular to a high-quality PVC heat-shrinkable sleeve. Background technique [0002] The heat-shrinkable sleeve has a special function of shrinking when heated, and it can shrink when heated above 98°C, which is convenient to use. The heat-shrinkable sleeve is a special polyolefin heat-shrinkable sleeve, also known as diatomaceous earth composite urea material. It is soft and elastic. It will shrink when heated (125°C), and is widely used in the insulation protection of various wiring harnesses, solder joints, and inductors, and the rust and corrosion protection of metal pipes and rods. [0003] The PVC heat-shrinkable sleeve has a special function of shrinking when heated, and it can shrink when heated above 98°C, which is convenient to use. The products are divided into two series of 85°C and 105°C according to the temperature resistance, and the specifications are Φ2-Φ200. The products compl...
