Abstract
A laminated silicate modified doublet high-density polyethylene winding piping material is used for wind pipe with high environmental stress cracking resistant performance. The production is carried out by taking doublet high-density polyethylene, cetane trimethyl-salmiac and vinyl-R-methoxyl-silane (R is alkyl with 3-12 atom) treating, and melting composite modifying. It achieves improvement of abrasive-resistant, roughness and machining performance.
Description
Technical field
The present invention relates to a kind of laminated silicate modified double-peak high-density polytene material, be particularly useful for the processing and manufacturing of the winding tube that environmental stress cracking resistance and ring stiffness have relatively high expectations.
Technical background
High-density polytene winding pipe is because pollution-free, corrosion-resistant (can adapt to concentration at the soda acid liquid below 10%), energy consumption are low, in light weight, simple installation, characteristics such as through-current capacity is big, the life-span is long, excellent shock resistance, development in recent years rapidly, the trend that substitutes the high material of energy consumption (as cement, cast iron, pottery etc.) tubing is gradually arranged, become the main products of water shoot and blow-off pipe.The unimodal high density polyethylene(HDPE) of main both at home and abroad employing is that basic raw material is made the draining high-density polytene winding pipe at present.But because the particularly homemade unimodal high density polyethylene(HDPE) environmental stress resistance of unimodal high density polyethylene(HDPE) is poor, ring stiffness, wear resistance and toughness are also undesirable simultaneously.In order to improve its over-all properties, once attempted with superfine talcum powder, thermoplastic elastomer (Liu Baiyuan, ' third generation large-caliber double-wall bellow strengthens the development and the application of toughened master batch ', " plastic working ", 2004,39 (1), 33-38), linear low density polyethylene (Wang Cheng ' research of blended and modified polyethylene tubing material ', " plastics science and technology ", 1999,08, p5) grade is carried out modification, though obtained some effects, because of the performance of unimodal high density polyethylene(HDPE) matrix resin own is limit still desirable not to the utmost.
Summary of the invention
The object of the invention is exactly the high-density polytene winding pipe PP Pipe Compound of a kind of excellent performance of preparation, significantly improves integration capabilities such as its environmental stress cracking resistance and ring stiffness, wear resistance and toughness.Another object of the present invention is exactly to improve the processing characteristics of high-density polytene winding pipe PP Pipe Compound, to satisfy the requirement of existing production technique.
The present invention selects for use double-peak high-density polytene to make matrix resin, and with lamella silicate modified double-peak high-density polytene winding pipe materials, its moiety comprises: organic illiteracy holder soil, double-peak high-density polytene, auxiliary agents such as toughner.Its weight proportion is: organic illiteracy holder soil: double-peak high-density polytene: auxiliary agents such as toughner=(15～45%): 1: (0.5～5%).Wherein: organic illiteracy holder soil is for handling expanded illiteracy holder soil (R is the alkyl of carbonatoms 3～12) through palmityl trimethyl ammonium chloride and vinyl-R-methoxy silane.Auxiliary agents such as toughner can be from polyoxyethylene, and ethylene-propylene copolymer is chosen any one kind of them in the styrene-butadiene copolymer at least.
The preparation method of laminated silicate modified double-peak high-density polytene winding pipe materials of the present invention; be that organic illiteracy holder soil and auxiliary agent are joined high-speed mixer high speed mixing 2～3 minutes by above-mentioned proportioning; make and give batch mixing uniformly; be that 100% double-peak high-density polytene mixes with weight ratio again; put into the double-screw extruding pelletizing machine; be warming up to 50～230 ℃; adjust 100～400 rev/mins of rotating speeds; the intercalation that carries out organic illiteracy holder soil is peeled off and is disperseed; extrude at last; traction, cooling, granulation.Wherein, the preparation method of organic illiteracy holder soil is for being 1～8% sodium Ji Mengtuo soil aqueous suspension with weight ratio concentration in 5～10% excessive palmityl trimethyl ammonium chloride aqueous solution of 80 ℃ of agitation and dropping, be incubated 1 hour, suction filtration, wash with water to no chlorion, join in the mixing machine after the drying, rotating speed with 40～60 rev/mins stirs at a slow speed, slowly spray into simultaneously 5% ethanolic soln (R is the alkyl of carbonatoms 3～12) of the vinyl-R-methoxy silane of equivalent, stirred at a slow speed 10～30 minutes in 30～40 ℃, cooling, blanking, packing.
The present invention selects for use double-peak high-density polytene to make matrix resin, its environmental stress cracking resistance F50 " 10000h, be ten times of unimodal high-density polyethylene resin, ring stiffness, wear resistance and toughness are also than unimodal high-density polyethylene resin height, use the layered silicate (organic illiteracy holder soil) after the special processing that organises composite modified to its fusion intercalation again, its over-all properties improves again.Double-peak high-density polytene melt viscosity height, rate of extrusion is low, and poor processability is difficult to satisfy the requirement of existing production technique.To after its modification, melt viscosity reduces with layered silicate (in organic illiteracy holder) in the present invention, and melt flow rate (MFR) improves, and processing characteristics is improved, thereby reaches the processing characteristics requirement of winding tube PP Pipe Compound.
Polyethylene-based nonpolar organic compound, the melt temperature height, melt viscosity is big, is difficult to guarantee the homodisperse of layered silicate in polyethylene melt and peel off by common blend and fusion.The present invention adopts through the special layered silicate (organic illiteracy holder soil) that organises after handling and makes compound intercalator and the specific composite modified technology of fusion intercalation, has guaranteed the homodisperse of layered silicate (organic illiteracy holder soil) in polyethylene melt and has peeled off.Because the bigger serface of disperse phase nano material, strong interface is active and highly active characteristic, the tubing that makes double-peak high-density polytene material after the modification produce has excellent ring stiffness, tensile property and vertical shrinking percentage.Layered silicate (organic illiteracy holder soil) consumption after handling when organising be double-peak high-density polytene weight 20～40% the time, it is maximum that the ring stiffness of winding tube reaches.
As shown in table 1 with the inventive method to the performance comparison data before and after the double-peak high-density polytene modification.
