Abstract
The invention provides a high heat conduction scraping-resistant modified polypropylene sleeve for a power cable. The high heat conduction scraping-resistant modified polypropylene sleeve is prepared from the following basic materials in part by weight: 100 parts of polypropylene resin, 5 to 15 parts of heat conduction aid, 0.25 to 0.5 part of silane coupling agent, 5 to 20 parts of talcpowder, 2 to 4 parts of impact modifier and 0.2 to 0.7 part of antioxygen. The high heat conduction scraping-resistant modified polypropylene sleeve has the advantages that: the heat conductivity and scraping resistance are greatly improved, trenchless construction of the power cable is facilitated, and the use safety of the power cable line is improved.
Description
Technical field
The present invention relates to a kind of plastic conduit, power cable modified polypropene sleeve pipe is hindered in particularly a kind of high heat conduction scratch resistance.
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 is more than 40 ℃ descends significantly (70 ℃ of strength degradation 2/3), the directional drilling of completion is laid in the PE comb in early days, found that the PE pipe is subjected to external force and is out of shape, influenced normally laying of later stage cable, so proof PE pipe is not suitable for the power cable protecting pipe.The power cable sleeve pipe needs to stand continuous scouring in transportation and laid processes, the scoring resistance of pipe is had higher requirement.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned technology, propose a kind of electrical cable protection sleeve with high heat conduction, scratch resistance wound.
For achieving the above object, the technical solution used in the present invention is such.This high heat conduction scratch resistance is hindered power cable and is made of 100 parts of acrylic resins, 5～15 parts of heat conduction auxiliary agents, 0.25～0.5 part of silane coupling agent, 5～20 parts of talcum powder, 2～4 parts of impact modifiers, 0.2～0.7 part in oxidation inhibitor with the modified polypropene sleeve pipe the basic material of weight part.
Wherein said heat conduction auxiliary agent is a kind of in silicon carbide, magnesium oxide, the aluminium sesquioxide; Impact modifier is polyethylene octene elastomer (POE).
At first that heat conduction auxiliary agent and coupling agent is even in high-speed mixer and mixing with acrylic resin, talcum powder, impact modifier, oxidation inhibitor again after evenly in high-speed mixer and mixing during production, transfer to granulation on the forcing machine at last, the pellet that obtains is hindered power cable modified polypropene sleeve pipe by extruder for shaping for the high heat conduction scratch resistance of the present invention.
Advantage of the present invention is: thermal conductivity and scoring resistance improve greatly, help the non-excavating construction of power cable, improve the safety in utilization of power cable pipeline.
