Abstract
A process for preparing cross-linked polyvinyl silane includes mixing polyethylene, diisoproplbenzene peroxide, vinyl triethoxyl silane, zinc stearate, tert [beta-(3,5-di-tert-butyl-4-hydroxyl-phenyl) propanoic] pentaerythritol ester and tri(2,4-tert-butyl phenyl) phosphite, stirring, extruding out, and immersing in water at 80 +/-5 deg. for 9-11 hrs. Its advantages are less consumption of trigger and cross-linking agent (decreased by 50%) and smooth surface of product.
Description
Technical field:
The invention belongs to the crosslinked method of polyethylene-silane.
Background technology:
Polyethylene can increase substantially mechanical property by crosslinking reaction, chemical resistance, ageing-resistant performance, wear resisting property, and good adhesiveproperties.Therefore be widely used in tubing, field of cables.Polyethylene is the technology (U.S.3 075948 (1963)) that occurs the sixties by silane grafting hydrolytic crosslinking, and is developed in the seventies.Poly before this crosslinking reaction is mostly by radiation crosslinking and peroxide crosslinking.Wherein radiation crosslinking equipment is extremely expensive, and application is restricted, and peroxide crosslinking is wayward owing to process, and quality of item is more difficult to get assurance.So, developed rapidly with regard to the main method that becomes polyethylene crosslinking very soon when crosslinked with silicane technology one occurs.At present industrial mostly with this method production polyethylene crosslinking product.Crosslinkable silane is associated with two kinds of methods: a kind of two-step approach of being succeeded in developing by Dow Corning company, be called Sioplas E technology [(U.S.3 646 155 (1972)) (Thomas B.Bowery M.wireJ.1977.10.88) (DE.2 736 513 (1976)) (DE.2 736 033 (1979))], the another kind of single stage method of being succeeded in developing by BICC and Naillefer company is called Monosil technology [(U.S.4117 195 (1978)) (GB.1 526 398 (1978))].
Sioplas E technology is the A material with base-material polyethylene, linking agent vinyl silanes, peroxide initiator, and the crosslinkable graft copolymer is made by the single screw extrusion machine extruding pelletization in the back that is mixed; With base-material polyethylene, catalyzer organotin, oxidation inhibitor is the B material, and the catalysis masterbatch is made by the single screw extrusion machine extruding pelletization in the back that is mixed; Then A, B are expected to mix.Make graft copolymer by the single screw extrusion machine extruding pelletization, make cross-linking copolymer by hydrolysis.Monsil technology is made graft copolymer by the single screw extrusion machine extrusion moulding after being mixed with base-material polyethylene, linking agent vinyl silanes, peroxide initiator, catalyzer organotin, oxidation inhibitor, makes cross-linking copolymer by hydrolysis.The shortcoming of Sioplas E is a complex process, and A material is can not storage period long, otherwise occur crosslinked, the following process difficulty.Sioplas E and Monosil technology all need the bigger auxiliary agent of adding proportion, make prescription complicated, and liquid oozes out operation inconvenience in the batch mixing, the metering misalignment, and wholesomeness is poor, raises the cost.Simultaneously the small amount of moisture in the course of processing also can with the reaction rapidly of ≡ Si-OR base, a spot of crosslinked phenomenon will be arranged in moulding process, about 10%, comprise that Si-O-Si and C-C are crosslinked, influential to continuous processing and product performance.Up to the present, these two kinds of technology still are difficult to make them to reach the level of processing of thermoplastic material.
Summary of the invention:
The purpose of this invention is to provide a kind of cross-linking process of polyethylene-silane, this method is by adding the lubricating type crosslinking accelerator, to promote crosslinking reaction and to improve complete processing.The lubricating type crosslinking accelerator that adds in this method prescription can improve the degree of crosslinking of product, has reduced initiator, and auxiliary dosages such as linking agent improve fabrication process condition simultaneously, makes continuous handling ease carry out.
Invention base reason is in grafting and the crosslinking reaction process, by the polymolecularity of lubricating type crosslinking accelerator, high dispersing initiator, linking agent, catalyzer, various functional agents are fully met, bring into play usefulness to greatest extent, this promotor itself has the promotion sulfuration in addition.The lubricating type crosslinking accelerator can produce inside and outside lubrication in the course of processing continuously, makes handling ease to reduce energy consumption.
It is 100 parts of polyethylene that the present invention adopts with the weight part base-material; Peroxide initiator is dicumyl peroxide or benzoyl peroxide 0.05-0.1 part; The vinyl silanes linking agent is vinyltrimethoxy silane or vinyltriethoxysilane 0.5-2 part; Catalyzer is dibutyl tin laurate 0.05-0.15 part; Oxidation inhibitor is wherein one or both 0.1 part of four [β-(3,5-di-t-butyl-4-hydroxyl-phenyl) propionic acid] pentaerythritol ester or three (2, the 4-tert-butyl-phenyl) phosphorous acid ester; The lubricating type crosslinking accelerator is: hydro carbons comprises: polyethylene wax, Poly Propylene Wax, polyoxyethylene, the metallic salt of hydroxy acid comprises: Zinic stearas, calcium stearate, lead stearate, the carboxylic acyloxy amine comprises: mustard acid amides, stearylamide, ethylenebisstearamide, wherein one or more 0.01-3 parts.Prescription optimum addition initiator is 0.07 part, and linking agent is 1 part, and catalyzer is 0.1 part, and oxidation inhibitor is 0.1 part, and crosslinking accelerator is 1 part.
Technological process of the present invention: with the base-material polyethylene, the initiator dicumyl peroxide, the linking agent vinyltriethoxysilane, crosslinking accelerator Zinic stearas, oxidation inhibitor four [β-(3,5-di-t-butyl-4-hydroxyl-phenyl) propionic acid] pentaerythritol ester, three (2, the 4-tert-butyl-phenyl) phosphorous acid ester stirs at height that normal temperature is mixed in the machine, extrudes in single screw extrusion machine, extrusion temperature is 140-175 ℃, the extruding graft thing in 80 ℃ ± 5 ℃ water 9-11 hour polyethylene-silane crosslinked.
The polyethylene crosslinking resin gel content 72.5% of the inventive method, tensile strength 36Mpa, elongation at break 800%, shock strength 15J/m is identical with the Monosi handicraft product with former Sioplas E.This prescription is common to Sioplas E and Monosi technology.
Carry out the silane graft reaction with this prescription, initiator and linking agent usage quantity can reduce half, reduce to 0.05-0.1% and 1% from traditional standard recipe 0.1-0.2% and 2% respectively, and degree of crosslinking still can reach 70-75%.The minimizing of liquid silane content, and with the mixing of Powdered promotor, avoided oozing out dripping and dropped down phenomenon.In addition in grafting and crosslinked continuous processing, overcome that to extrude torque big in the past, processing difficulties, the screw flutes material stock generates the shortcoming of gel grain.Show as little power consumption, extrude easily, product surface is smooth, and color and luster is even.Promotor price and base-material are suitable, and the decrement of other auxiliary agent has reduced cost significantly.
