Abstract

The invention discloses a stabilizer composition for a special material for a polyethylene electric wire cable. Aiming at the deficiency that a stabilizer for the special material for the polyethyleneelectric wire cable in the prior art has a common anti-oxidation effect, the types and mass ratios of hindered phenol stabilizers, phosphite ester stabilizers, a thio-ester stabilizer and acid acceptors are selected, and a series of stabilizer compositions capable of improving the anti-oxidation stability of the special material for the polyethylene electric wire cable are obtained.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, relates to fine chemical industry, in particular to a stabilizer composition for polyethylene wire and cable special materials. Background technique [0002] Wire and cable products are widely used, involving industries such as electric power, communication, and electrical equipment. The raw materials used for wire and cable special materials mainly include PE and PVC. PVC is relatively unstable to heat and light, and has potential environmental hazards. Developed countries such as Europe and the United States have banned the use of PVC insulated cables in tall buildings and public places in the early 1980s. my country's relevant laws and regulations also explicitly require that important buildings prohibit the use of polyvinyl chloride wires and cables, and must use halogen-free low-smoke cross-linked polyolefin insulated wires and cables to avoid a large amount of smoke and chlorine ...
