Abstract

The invention provides a high elasticity PE modified material, which comprises the following components, by weight, 100 parts of the PE, 15-40 parts of POE, 10-30 parts of a filler, 20-40 parts of carbon black, and 5-10 parts of a coupling agent. The high elasticity PE modified material allows the Shore hardness and the elastic modulus of a PE resin to be greatly improved, prepared products subjected to bearing deformation to be rapidly restored and the restoration cost to be low, and is especially suitable for PE fused saddle-shaped pipe fittings to be subjected to rapid rectification and circle-restoration.

Description

Material modified and the application on rectification fourth contact PE pipe fitting of snappiness PE
Technical field
The present invention relates to the material modified and application on rectification fourth contact PE pipe fitting of a kind of snappiness PE.
Background technology
At present, the pipeline that be used to feed water, buried pipeline all adopts polythene material mostly among the public works such as combustion gas.Wherein need use a large amount of electric melting pipe fittings, safe in utilization secure for guaranteeing pipeline, the performance requriements of electric melting pipe fittings is higher than the requirement of tubing.Wherein electric smelting saddle type class pipe fitting is widely used, and it comprises the collet of bottom, and the saddle type main body on top is located at the intravital boring device of saddle type master, and the tightness system of being located at saddle type main body upper end.When electric smelting saddle type pipe fitting uses in the boring device bore cutter move up and down along said saddle type main body inner wall, and on pipeline, hole through blade.Under the powerful effect of perforate power, saddle type main body is very yielding, if saddle type main body can not be corrected fourth contact fast, can cause deviations, and perforate is unfavorable.
Vilaterm raw material self Young's modulus is less, and surface hardness is low, and creep resistance is low, and the ring stiffness of the tubing of making can't meet the demands, and it is all the more so especially to correct the pipe fitting of fourth contact fast at needs.
Summary of the invention
The purpose of this invention is to provide the material modified and application on rectification fourth contact PE pipe fitting of a kind of snappiness PE, in order to solve defective and the deficiency that above-mentioned prior art exists.
For realizing above-mentioned purpose, a kind of snappiness PE of the present invention is material modified, and it comprises following component and content (weight part):
Said Vilaterm is more than one of high density polyethylene(HDPE) and ultrahigh molecular weight polyethylene(UHMWPE);
Said POE is that U.S. DOW chemical company is the thermoplastic elastomer that the narrow relative molecular mass of having of catalyzer distributes and uniform short-chain branch distributes with the metallocene.This elastomeric salient features is very outstanding, and the performance index aspect a lot of have surpassed the ball gonosome.The POE molecular structure is similar with terpolymer EP rubber; Therefore POE also can have excellent properties such as ageing-resistant, anti-ozone, resistant to chemical media; Through carrying out crosslinked to POE; The heat resisting temperature of material is enhanced, and tension set reduces, and main mechanical property such as tensile strength, tear strength all has significant improvement.And POE and Vilaterm have good affinity, and in the blending and modifying process, dispersity is better;
Said filler is more than one in talcum powder, nano-calcium carbonate, calcium titanate, wollastonite powder, mica powder, kaolin, brucite powder, wilkinite, zeyssatite and the pumice sand;
Said coupling agent is more than one of silane coupling agent, titanate coupling agent, aluminate coupling agent, rare-earth coupling agent and aluminium titanium composite coupler.
The material modified preparation method of above-mentioned snappiness PE provided by the invention is following:
1) polyvinyl resin, POE, filler and carbon black are added in the high-speed mixer successively, 50～60 ℃, mixed at high speed 30～50min emits;
2) then it is sent in the twin screw extruder, the extrusion temperature of control forcing machine is 220～240 ℃, extruding pelletization;
3) handle through radiation crosslinking again that to be snappiness PE material modified.
The present invention also provides above-mentioned snappiness PE material modified application on the PE electric melting pipe fittings;
Further, the application on the material modified PE electric smelting saddle type pipe fitting of correcting fourth contact at needs fast of said snappiness PE.
Material modified shore hardness and the Young's modulus that has increased substantially polyvinyl resin of snappiness PE provided by the invention, fast quick-recovery behind the prepared product stress deformation, and with low cost, need to be specially adapted to the PE electric smelting saddle type pipe fitting of rectification fourth contact fast.
