Abstract
The utility model discloses a cable protective pipe, in particular discloses a glass fiber reinforced plastic and modified polyvinyl chloride composite cable conduit, characterized by comprising an inner pipe and an outer pipe, wherein the inner pipe is a modified polyvinyl chloride pipe, the outer pipe is a glass fiber reinforced plastic pipe, the glass fiber reinforced plastic pipe and the modified polyvinyl chloride pipe are bonded through a bonding layer therebetween, and the thickness of the pipe wall of the modified polyvinyl chloride pipe is 2-4 mm. The glass fiber reinforced plastic and modified polyvinyl chloride composite cable conduit enables glass fiber reinforced plastic pipe and modified polyvinyl chloride to be composed in one, thereby not only utilizing the high strength and high heat resistance of the glass fiber reinforced plastic, but also avoiding defect of a glass fiber reinforced plastic cable conduit; simultaneously a thinner modified polyvinyl chloride pipe is used as the inner layer, thereby avoiding various defects of being low in strength and low in heat resisting temperature, etc.; and the composite cable conduit simultaneous utilizes the superiority of the two materials and can replace the various prior cable conduits.
Description
(1) technical field
The utility model relates to a kind of cable sheath tube, particularly a kind of fiberglass and modified polyvinyl chloride 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 utility model provides a kind of mechanical property is good, heat resistance is high, safe and reliable fiberglass and modified polyvinyl chloride composite cable conduit in order to remedy the defective of prior art.
The utility model is realized through following technical scheme:
A kind of fiberglass and modified polyvinyl chloride composite cable conduit is characterized in that: pipe and outer tube in comprising, and interior pipe is the modified polyvinyl chloride 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 polyvinyl chloride pipe.
This fiberglass and modified polyvinyl chloride composite cable conduit, the pipe thickness of modified polyvinyl chloride pipe is 2-4mm.
This fiberglass and modified polyvinyl chloride composite cable conduit are exactly to be the novel cable protection tube of one with thermoset plastics and thermoplastics are compound specifically, and the neither one manufacturer production is compound to one with two kinds of materials and is used for cable sheath tube at present.
The beneficial effect of the utility model is: this fiberglass and modified polyvinyl chloride composite cable conduit; Be compounded in one to fiberglass and modified polyvinyl chloride, not only utilize high strength, the high-fire resistance ability of fiberglass, avoided the defective of fiberglass cable duct tube again; Use thin modified polyvinyl chloride pipe as internal layer simultaneously; Avoid various defectives such as simple strength for polyvinyl chloride 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 utility model is further described.
Among the figure, 1 glass reinforced plastic pipe, 2 tack coats, 3 modified polyvinyl chloride pipes.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.
Among Fig. 1; This fiberglass and modified polyvinyl chloride composite cable conduit, pipe and outer tube in comprising, interior pipe is a modified polyvinyl chloride pipe 3; Outer tube is a glass reinforced plastic pipe 1; Glass reinforced plastic pipe 1 and modified polyvinyl chloride 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 polyvinyl chloride pipe 3 is for bring up to more than 155 ℃ the heat resisting temperature of polyvinyl chloride through crosslinked method; Simultaneously thinner; The pipe thickness of modified polyvinyl chloride pipe 3 is 2-4mm; The cable heat radiation is delivered to outer field glass reinforced plastic pipe 1 faster, has improved the heat resistance of pipeline like this.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 polyvinyl chloride particles of modification is made the thin modified polyvinyl chloride 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 polyvinyl chloride composite cable conduit.
Claims (2)
1. fiberglass and modified polyvinyl chloride composite cable conduit; It is characterized in that: pipe and outer tube in comprising; Interior pipe is modified polyvinyl chloride pipe (3), and outer tube is glass reinforced plastic pipe (1), and glass reinforced plastic pipe (1) is mutually bonding through middle tack coat (2) with modified polyvinyl chloride pipe (3).
2. fiberglass according to claim 1 and modified polyvinyl chloride composite cable conduit is characterized in that: the pipe thickness of modified polyvinyl chloride pipe (3) is 2-4mm.
