Problems solved by technology

Cables made of traditional silane cross-linked polyethylene formulations are not good enough to inhibit the catalytic aging of heavy metal ions, and some heavy metal ions are still inactive, and the effect of copper damage is obvious, which makes the cable aging quickly and the service life is short.

Abstract

The invention relates to a production formula of silane crosslinked polyethylene. The formula comprises the following components in parts by weight: 940-960 parts of mixed formulations, 45-55 parts of special-purpose plastic materials B, 0.6-1 part of anti-oxidant, 0.4-0.8 part of copper inhibitor and 3-3.5 parts of alkyl oil. The production formula disclosed by the invention is reasonable in material matching, convenient to manufacture, capable of inhibiting catalytic ageing of heavy metal ions, and obvious in copper pollution-resisting effect, so that service life of a product can be prolonged.

Description

technical field [0001] The invention relates to the technical field of cable sheath manufacture, in particular to a production formula of silane crosslinked polyethylene. Background technique [0002] In the presence of organic peroxides, ordinary polyethylene is subjected to a certain temperature and mechanical force to graft silanes containing unsaturated vinyl groups and easily hydrolyzed alkoxy polyfunctional groups onto the main chain of polyethylene, and then Under the action of water and silanol condensation catalyst, the graft is hydrolyzed and condensed to form Si-O-Si cross-linking bonds to obtain silane cross-linked polyethylene. Cables made of traditional silane cross-linked polyethylene formulations are not good enough to inhibit the catalytic aging of heavy metal ions, and some heavy metal ions are still inactivated. The effect of copper damage is obvious, which makes the cable age quickly and the service life is short. Contents of the invention [0003] The...
