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
The present invention relates to cable sheath manufacturing technology field, specifically a kind of production formula of organosilane crosslinked polyethylene.
Background technology
By common polythene organo-peroxide exist under, through certain temperature and mechanical force, the multi-functional Silane Grafted of alkoxyl group that makes to contain unsaturated ethylene thiazolinyl and be easy to hydrolysis is to poly main chain, then by this grafts under water and silicon alcohol condensation catalyst effect, be hydrolyzed, and condensation formation Si-O-Si cross-link bond, obtain organosilane crosslinked polyethylene.The cable that the formula of traditional organosilane crosslinked polyethylene is made, it is good not that it suppresses the aging damaging effect of the catalysis of heavy metal ion, still has part heavy metal ion not lose activity, and copper evil successful makes cable aging fast, and work-ing life is short.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of material adapted reasonably, convenient manufacture, can suppress the formula of the aging harm of the catalysis of heavy metal ion, i.e. a kind of production formula of organosilane crosslinked polyethylene.
Technical problem to be solved by this invention realizes by the following technical solutions:
A production formula for organosilane crosslinked polyethylene, this formula comprises mixed preparation, the special B material of plastics, oxidation inhibitor, anti copper agent and alkane oil, the parts by weight of each component are as follows:
The shared optimum weight umber of described each component is as follows:
Described mixed preparation is mixed according to the ratio of 5:4:10 by linear low density polyethylene, Low Density Polyethylene, high-pressure polyethylene material.
The performance of part component and effect are as follows:
Linear low density polyethylene: be milky white granules nontoxic, tasteless, odorless, density is 0.918～0.935g/cm
3there is higher softening temperature and melt temperature, have the advantages such as intensity is large, good toughness, rigidity is large, heat-resisting, winter hardiness is good, also there is good environmental stress crack resistance, the performance such as impact strength, tear-resistant intensity, and can acid-and base-resisting, organic solvent etc.
Low Density Polyethylene: for injection-molded item, packaging material for food, medical apparatus, medicine, blowing slush molding goods, fiber etc.
High-pressure polyethylene: low-molecular-weight is generally colourless, odorless, tasteless, nontoxic liquid, the sterling of high molecular is oyster white waxy solid powder, fusing point: 92 ℃, relative density: 0.95, be used for making agricultural, food and industrial packaging film, electric wire is coated and coating, composed paper etc.
Oxidation inhibitor: in the time that it only exists on a small quantity in polymeric system, just can delay or suppress the carrying out of polymkeric substance oxidising process, thereby stop the aging of polymkeric substance and extend its work-ing life, " anti-aging agent " is otherwise known as.
Anti copper agent: there is the very strong aging ability of inhibition heavy metal ion catalysis, anti-copper evil effect significantly and have with resin-phase dissolubility good, good dispersity, do not move, do not pollute, water-fast, oil extractable is good, does not affect the advantage such as electrical insulation capability and other performance of resin.
Alkane oil: high solvency power, excellent low-temperature performance, with some resin and the good compatibility of polymkeric substance, with good speedup and the mutual solubility of rubber.
The invention has the beneficial effects as follows: the present invention have material adapted rationally, convenient manufacture, the catalysis that can suppress heavy metal ion is aging, anti-copper evil successful, thereby can extend work-ing life of product.
