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 outer surface of the wall of the modified PP tube is coated with an adhesive layer and then fiber glasses dipped in unsaturated polyester resin are annularly or spirally wound onto the surface of the adhesive layer. 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
(1) technical field
The present invention relates to a kind of manufacture method of cable sheath tube, particularly the manufacture method of a kind of fiberglass and modified polypropylene composite cable conduit.
(2) background technology
Glass fibre reinforced plastic cable conduit (standard with by name " fiberglass reinforced plastics cable duct tube ") is protection tubing commonly used in the cable laying of various places in recent years; have the advantages such as intensity is high, corrosion-resistant, insulation, construction saving convenience, long service life; without 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 although the glass fibre reinforced plastic cable conduit has lot of superiority but has critical defect, in case cable sheath or the traction iron wire when wearing cable scratch the glass fibre of glass fibre reinforced plastic cable pipe inner wall, just can cause the glass fibre delamination, glass fibre is wrapped in the cable outside in the body, fiber twines more and more, causing cable not advance can not retreat, and causes stuck cable.Existing other various cable duct tubes have various defectives: high such as steel pipe and plastic-coated steel intensity, project cost is high, and difficulty of construction is large, and is diamagnetic poor, easily produces eddy current, fragile difficult reparation of coating layer; Polyvinyl pipe of cement (sepiolite pipe) weight is large, and just, intensity is low, resistance to acids and bases is poor, easily infiltration, and the bending resistance Qucha, frangibility is broken, behind the stuck cable, is difficult to change cable, need make based process, and construction labour intensity is large, has increased cost to engineering; Various plastic tubes such as the hoop rigidities such as MPP, PVC are poor, can not bear weight, and are not inflammable frangible, thermo-labile, anti-aging, the life-span is short.
(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 polypropylene composite cable conduit and manufacture method thereof in order to remedy the defective of prior art.
The present invention is achieved through the following technical solutions:
The manufacture method of a kind of fiberglass and modified polypropylene composite cable conduit, this conduit comprises inner and outer tubes, and inner tube is the modified polypropene pipe, and outer tube is glass reinforced plastic pipe, and glass reinforced plastic pipe is mutually bonding by middle tack coat with the modified polypropene pipe.This conduit is by modified polypropylene particles is made the modified polypropene pipe by expressing technique, and at its outer surface brushing one deck adhesive linkage, then the adhesive linkage surface with the glass fiber winding modified polypropene pipe that floods unsaturated polyester resin forms this conduit.
[0005] this fiberglass and modified polypropylene composite cable conduit, the pipe thickness of modified polypropene pipe are 2-4mm.
The invention has the beneficial effects as follows: this fiberglass and modified polypropylene composite cable conduit, fiberglass and modified polypropene are compounded in one, not only utilize high strength, the high-fire resistance energy of fiberglass, avoided again the defective of glass fibre reinforced plastic cable conduit, use simultaneously thinner modified polypropene pipe as internal layer, avoid the various defectives such as simple strength of PP is low, heat resisting temperature is low, utilized simultaneously the superiority of bi-material, can substitute existing various cable duct tube.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
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 polypropylene composite cable conduit, comprise inner and outer tubes, inner tube is modified polypropene pipe 3, outer tube is glass reinforced plastic pipe 1, glass reinforced plastic pipe 1 and modified polypropene pipe 3 is mutually bonding by middle tack coat 2, and tack coat 2 is bonded into one inner and outer tubes securely, carries outside two Guan Buhui layerings under the effect of power.The method of modifying of modified polypropene pipe 3 is for bring up to more than 155 ℃ polyacrylic heat resisting temperature by 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 like this heat resistance of pipeline.Be better than the plastic tube of other various materials as inner tube take MPP (modified polypropene), because MPP is modified polypropene, its heat resistance is better than the 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, namely use glass fiber impregnated unsaturated polyester resin, carrying out hoop according to Control Program for Microcomputers [Digital Research] twines and spiral winding, hoop by design twines and spiral winding provides outer year performance of body, takes full advantage of the performance of the high-strength light of glass-reinforced plastic material.When producing, the polypropylene GRANULES of modification is made the thinner modified polypropene pipe 3 of wall thickness by expressing technique, cut as required suitable length, this pipe is carried out outer surface to be processed, external coating one deck tack coat 2 outside, then the pipe after processing is installed on the proper mold, 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 by the laying that designs, twine complete, wait resin solidification after, the cutting edging namely obtain product fiberglass and modified polypropylene composite cable conduit.
