Abstract
The invention relates to a chlorinated polyvinyl chloride casing of a power cable with high thermal conductivity, which comprises basic materials of the following weight portions: 100 portions of PVC-C (chlorinated polyvinyl chloride) resin, 30-60 portions of SAN (styrene-acrylonitrile) resin, 2-6 portions of heat conduction agent, 4-7 portions of stabilizer, 1-2.5 portions of lubricating agent, 6-9 portions of anti-impact modifier, 6-10 portions of calcium carbonate, 2-5 portions of processing aid and a small number of pigments. The heat conduction aid adopts nano-alumina. The invention has the advantages of good thermal conductivity and excellent physical and mechanical properties.
Description
Technical field
The present invention relates to a kind of plastic conduit, particularly a kind of high heat conduction power cable is used the chlorinated polyvinyl chloride sleeve pipe.
Background technology
Much more early stage with PE solid wall pipe or PE spiral tube etc. as non-excavation power cable sleeve pipe; But these two kinds of pipes intensity when temperature 40o С is above descends significantly (70o С strength degradation 2/3); The directional drilling of completion is laid in the PE comb in early days; Found that PE pipe receives external force and is out of shape, and has influenced normally laying of later stage cable, so proof PE pipe is not suitable for the power cable protecting pipe.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned technology, propose a kind of high heat conduction power cable and use the chlorinated polyvinyl chloride sleeve pipe.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is such.This high heat conduction power cable is made up of the basic material of weight part with the chlorinated polyvinyl chloride sleeve pipe, and 100 parts of PVC-C resins, 30～60 parts of SAN resins, 2～6 parts of thermal conducting agents, 4～7 parts of stablizers, 1～2.5 part of lubricant, 6～9 parts of impact modifiers, 6～10 parts in lime carbonate, 2～5 parts of processing aids, pigment are a small amount of.
Wherein said heat conduction auxiliary agent is a nano aluminium oxide.
Advantage of the present invention is: thermal conductivity is good, physical and mechanical property is excellent.
Specific embodiments
High heat conduction scratch resistance is hindered power cable and used each basic weight of material part of modified polypropene sleeve pipe to be: 100 parts of PVC-C resins, 50 parts of SAN resins, 4 parts of thermal conducting agents, 6.5 parts of stablizers, 1.8 parts of lubricants, 8 parts of impact modifiers, 8 parts in lime carbonate, 3 parts of processing aids, pigment are a small amount of.
Wherein said heat conduction auxiliary agent is a nano aluminium oxide.
A kind of novel electric power control of the present invention is equipped with technology and is undertaken by following operation:
A) by weight,, mix, and in this TR, keep more than 10 minutes at 90～120 ℃ with PVC-C resin, SAN resin, thermal conducting agent, stablizer, lubricant, impact modifier, lime carbonate, processing aid, pigment;
B) said mixture is put into cold mixer and be cooled to 25～45 ℃, import dry feed bin;
C) compound in the dry feed bin is extruded, processed tubing behind vacuum sizing and the cooling forming through the awl twin screw extruder;
D) fixed length cutting, enlarging, packing.
The high heat conduction power cable of the present invention adopts nano aluminium oxide as thermal conducting agent with the chlorinated polyvinyl chloride sleeve pipe, and heat conductivility improves greatly, the nano aluminium oxide good dispersivity, and the physical and mechanical property of pipe is excellent.
What particularly point out is, specific embodiments is the more representational example of the present invention, and obvious technical scheme of the present invention is not limited to such scheme, and a lot of forms can also be arranged.Present technique field personnel all should think invention which is intended to be protected with disclosed mention or technical scheme that it is associated among the present invention.
