Abstract

The invention discloses a cable sheath tube, in particular to a composite cable duct made from glass fiber reinforced plastics (GFRP) and modified polypropylene (PP). The composite cable duct made from the GFRP and the modified PP is characterized by comprising an inner tube and an outer tube, wherein, the inner tube is a modified PP tube, and the outer tube is a GFRP tube; the GFRP tube is bonded with the modified PP tube through a middle bonding layer; and the thickness of the wall of the modified PP tube is 2-4mm. The composite cable duct has the beneficial effects that since the GFRP is compounded with the modified PP, the advantages of high strength and strong heat resistance of the GFRP can be used and the defects of a GFRP cable duct is avoided; meanwhile the thinner modified PP tube is taken as an inner layer so as to avoid various defects of a single PP tube, such as low strength, low heat-resistance temperature and the like; and the advantages of the two materials are utilized at the same time, thus the composite cable duct can replace the existing various cable ducts.

Description

A kind of fiberglass and modified polypropene composite cable conduit
(1) technical field
The present invention relates to a kind of cable sheath tube, particularly a kind of fiberglass and modified polypropene composite cable conduit.
(2) background technology
Fiberglass cable duct tube (standard with by name " fiberglass reinforced plastics cable duct tube ") is a protection tubing commonly used in the cable laying of various places in recent years; Have intensity height, corrosion-resistant, insulation, construction and save advantages such as convenience, long service life; Be no galvano-cautery, nonmagnetic energy-conserving and environment-protective tubing; Be specially adapted to the laying of single-core cable, in the 110KV cable laying, use very extensive.Along with using and engineering construction finds that though the fiberglass cable duct tube has lot of superiority but has critical defect; In case cable sheath or the traction iron wire when wearing cable scratch the glass fiber of fiberglass cable duct tube inwall; Just can cause the glass fiber delamination, glass fiber is wrapped in the cable outside in the body, and fiber twines many more more; Causing cable not advance can not retreat, and causes stuck cable.Existing other various cable duct tubes have various defectives: high like steel pipe and plastic-coated steel intensity, project cost is high, and difficulty of construction is big, and is diamagnetic poor, is prone to produce eddy current, fragile difficult reparation of coating layer; Polyvinyl pipe of cement (sepiolite pipe) weight is big, and just, intensity is low, resistance to acids and bases is poor, is prone to infiltration, the bending resistance Qucha, and frangible is broken, behind the stuck cable, is difficult to change cable, need make based process, and construction labour intensity is big, has increased cost to engineering; Various plastic tubes such as hoop rigidity such as MPP, PVC are poor, can not bear weight, and are inflammable frangible, thermo-labile, not anti-aging, life-span weak point.
(3) summary of the invention
The present invention provides a kind of mechanical property is good, heat resistance is high, safe and reliable fiberglass and modified polypropene composite cable conduit in order to remedy the defective of prior art.
The present invention realizes through following technical scheme:
A kind of fiberglass and modified polypropene composite cable conduit is characterized in that: pipe and outer tube in comprising, and interior pipe is the modified polypropene pipe, and outer tube is a glass reinforced plastic pipe, and glass reinforced plastic pipe is mutually bonding through middle tack coat with the modified polypropene pipe.
This fiberglass and modified polypropene composite cable conduit, the pipe thickness of modified polypropene pipe is 2-4mm.
The invention has the beneficial effects as follows: this fiberglass and modified polypropene composite cable conduit; Be compounded in one to fiberglass and modified polypropene, not only utilize high strength, the high-fire resistance ability of fiberglass, avoided the defective of fiberglass cable duct tube again; Use thin modified polypropene pipe as internal layer simultaneously; Avoid various defectives such as simple strength of PP is low, heat resisting temperature is low, utilized the superiority of two kinds of materials simultaneously, can substitute existing various cable duct tube.
(4) description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Accompanying drawing 1 is the cross-sectional schematic of fiberglass of the present invention and modified polypropene composite cable conduit.
Among the figure, 1 glass reinforced plastic pipe, 2 tack coats, 3 modified polypropene pipes.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.
Among Fig. 1; This fiberglass and modified polypropene composite cable conduit, pipe and outer tube in comprising, interior pipe is a modified polypropene pipe 3; Outer tube is a glass reinforced plastic pipe 1; Glass reinforced plastic pipe 1 and modified polypropene pipe 3 is mutually bonding through middle tack coat 2, and pipe and outer tube were bonded into one securely in tack coat 2 made, and carries two Guan Buhui layerings under the effect of power outside.The method of modifying of modified polypropene pipe 3 is for bring up to more than 155 ℃ polyacrylic heat resisting temperature through crosslinked method; Simultaneously thinner; The pipe thickness of modified polypropene pipe 3 is 2-4mm, and the cable heat radiation is delivered to outer field glass reinforced plastic pipe 1 faster, has improved the heat resistance of pipeline like this.With MPP (modified polypropene) is the plastic tube that interior pipe is better than other various materials, and because of MPP is a modified polypropene, its heat resistance is better than plastics such as polyvinyl chloride, thereby guarantees the requirement of cable heat radiation.The production technology of glass reinforced plastic pipe 1 is for adopting winding process; Promptly use glass fiber impregnated unsaturated polyester resin; Carry out hoop winding and spiral winding according to Control Program for Microcomputers [Digital Research]; Hoop winding and spiral through design twine the outer year performance that body is provided, and make full use of the performance of the high-strength light of glass-reinforced plastic material.When producing, the PP GRANULES of modification is made the thin modified polypropene pipe 3 of wall thickness through expressing technique, cut suitable length as required; This pipe is carried out outer surface handle, external coating one deck tack coat 2 is installed the pipe after handling on the proper mold then outside; Making at the enterprising oozy glass steel pipe 1 of glass reinforced plastic pipe production line; Specifically flood unsaturated polyester resin with long glass fibres exactly, carry out hoop or spiral winding through the shop layer that designs, winding finishes; Behind resin solidification, the cutting edging promptly obtains product fiberglass and modified polypropene composite cable conduit.
