Abstract
The invention provides a high heatproof PE modified material and its application in saddle type tee pipe joints. The high heatproof PE modified material comprises the following components of: by weight, 50-80% of heatproof polyethylene (PE-RT), 5-10% of a carrier resin, 10-40% of a filler, 1-3% of a coupling agent and 2-8% of a lubricating dispersant. The above high heatproof PE modified material is especially suitable for blind flanges of the saddle type tee pipe joints. According to the technical scheme, the technical problem that rigidness of a high heatproof PE material is insufficient is solved by the addition of a toughening elastic master batch. The high heatproof PE modified material requires simple technology and low cost, is easy to popularize and apply, is especially applied in the manufacturing of the saddle type tee pipe joints, and has excellent application performance as well as market potential.
Description
Technical field
The present invention relates to the material modified and application in the saddle type tee pipe fitting of a kind of high heat-resisting PE.
Background technology
China's floor heating tubing also has PP-R (atactic copolymerized polypropene), PP-B (shock resistance Vestolen PP 7052) and PB materials such as (polybutene-1s) certainly with PEX (crosslinked polyethylene) Guan Weizhu at present.In use there are many shortcomings in these tubing:
Need be crosslinked when cross-linked polyethylene pipe is produced, the production technique relative complex is had relatively high expectations to producer's technology controlling and process level, and quality receives the influence of technology bigger, in case degree of crosslinking goes wrong, its use properties will seriously descend.Crosslinked polyethylene is a thermoset tubing in addition, therefore can't recycling, environment protection has been brought negative impact.
The atactic copolymerized polypropene poor toughness, and shock resistance PA tube heat resisting and pressure resisting property is relatively poor, flexibility is poor, and therefore the material as the heat-resisting pipe fitting of height all is not suitable for.Polybutylenes material oxygen transmission rate is high, is prone to cause system's corrosion, and costs an arm and a leg and also limited its use.
To above problem, new high heat-proof polythene tubing-PE-RT has appearred.PE-RT adopts specific molecule design and the ethene of synthesis technique production and the multipolymer of octene, has controllable side chain distributed architecture.This novel fire resistant non-crosslinked polyethylene pipe material has need not be crosslinked, be prone to processing, recyclable (feature of environmental protection), can weld, characteristics such as snappiness is good, heat-conductive characteristic is good, be unusual ideal floor heating used to make hot water pipe.
But PE-RT also exists some defectives, and PE-RT belongs to medium-density polyethylene, and is therefore flexible good, but rigidity is not enough, and Young's modulus is 550MPa only, can cause the pipeline planeness bad, flexible, yielding like this.In order to ensure safe in utilization, the rigidity of electric melting pipe fittings requires will be apparently higher than the requirement of pipe fitting in the pipeline, and wherein the saddle type tee pipe fitting is all the more so, can directly influence its assembly yield and work-ing life, security.
Summary of the invention
The purpose of this invention is to provide the material modified and application in the saddle type tee pipe fitting of a kind of high heat-resisting PE, in order to solve defective and the deficiency that above-mentioned prior art exists.
For realizing above-mentioned purpose, a kind of high heat-resisting PE of the present invention is material modified, and it comprises following components in weight percentage:
Said vector resin is PS, Vilaterm, Vestolen PP 7052, acrylonitritrile-styrene resin, BS, acrylonitrile-butadiene-styrene copolymer or terpolymer EP rubber;
Said weighting agent is more than one in talcum powder, lime carbonate, wollastonite powder, mica powder, kaolin, brucite powder, wilkinite, zeyssatite and the pumice sand;
Big effective of said weighting agent length-to-diameter ratio, two or more powder mix is more effective than single powder;
Said coupling agent is more than one in silane coupling agent, titanate coupling agent, aluminate coupling agent, rare-earth coupling agent and the aluminium titanium composite coupler;
The effect of coupling agent is directly to form thin film on the weighting agent surface with chemistry or physical force, increases avidity;
Said lubricant is more than one in paraffin, polyethylene wax, OPE, Poly Propylene Wax, lipid acid, soap, fatty amide and the fatty ester;
The effect of lubricant can also impel master batch with the PE-RT melt blending time, to be dispersed in the matrix resin uniformly except that guarantee that weighting agent better disperses in vector resin.
The material modified preparation method of the heat-resisting PE of above-mentioned height may further comprise the steps:
1) lubrication dispersing agent and coupling agent mix at high-speed mixer and weighting agent, are coated on the weighting agent surface;
2) add vector resin again and mix, plastify in the compound adding dual-screw pelletizer, granulation, earnestly, the air-cooled filler parent granule for preparing;
3) filling master batch carries out melt blending with PE-RT again, and it is material modified that extruding pelletization prepares high heat-resisting PE.
The present invention also provides the heat-resisting PE of above-mentioned height material modified application in the saddle type tee pipe fitting, is specially adapted to blind plate.
Technical scheme of the present invention, through adding the insufficient technical problem of rigidity that toughness reinforcing elasticity masterbatch has solved high heat-resisting PE material, technology is simple; Low-cost; Be easy to apply,, have good use properties and market potential especially for making the saddle type tee pipe fitting.
