Abstract
The invention discloses a polyethylene anti-copper functional masterbatch, and mainly relates to the field of polymer materials, in particular to a functional masterbatch made of a polymer material. The polyethylene anti-copper functional masterbatch consists of the following components: 75 to 85 percent of low-density polyethylene, 9.2 to 20 percent of anti-copper agent, 2 to 5 percent of GL-3 wax, and 0.8 to 1 percent of antioxidant. In the functional masterbatch adopting the formula, the anti-copper agent is taken as a masterbatch core and a proper amount of antioxidant is added at the same time, so that the anti-copper masterbatch not only can make copper ions inactivate and reduce the side effect of the copper ions on a copper-core coating layer, but also is not decomposed within the range of processing temperatures and has rather processing stability at the same time.
Description
Technical field
The present invention relates generally to polymeric material field, especially the anti-copper masterbatch of macromolecular material functional master batch, particularly polyethylene.
Background technology
In recent years, along with the development of electric power, telecommunications, what various cables, electrical equipment used mostly is copper core cable, and its external insulation coating layer mostly is the polyolefins Plastic Resin greatly.Such cable in use, because long-term exposure is under physical environment, the polyolefine coating layer takes place photooxidation resistance and the thermo-oxidative ageing except being subjected to effects such as light, heat, the cupric ion that appraises at the current rate in the copper core passes through transfer transport, also can the polyolefinic oxidative degradation of catalysis, accelerated the degradation with aging process of polyolefine coating layer.When the preparation cable and wire, though the polyolefine coating layer adds oxidation inhibitor often in processing, copper can be offset the effect of oxidation inhibitor, causes the weathering process of coating layer to be quickened.Therefore, in the electric wire preparation process, on the basis of an amount of adding oxidation inhibitor, also should consider the influence of copper to weathering process.
Summary of the invention
The purpose of this invention is to provide the anti-copper functional master batch of a kind of polyethylene.
The anti-copper functional master batch of a kind of polyethylene of the present invention, it consists of:
New LDPE (film grade) 75%----85%
Anti copper agent 9.2%----20%
GL-3 wax 2%-----5%
Oxidation inhibitor 0.8%----1%
The anti-copper functional master batch of above-mentioned a kind of polyethylene is characterized in that described anti copper agent is N, N '-double salicylaldehyde contract quadrol or 3-amino-1,2,4-triazole.
The anti-copper functional master batch of above-mentioned a kind of polyethylene, described oxidation inhibitor are 2-mercaptobenzimidazole or N-phenyl-1-naphthylamine or N-phenyl-2-naphthylamines.
Adopting the functional master batch of above-mentioned prescription, is masterbatch nuclear with the anti copper agent, is aided with an amount of oxidation inhibitor simultaneously, make the anti-copper masterbatch of the present invention that cupric ion is lost activity, reduce its side effect, also in the processing temperature scope, do not decompose simultaneously, have suitable processing stability copper core coating layer.
