Abstract
The utility model provides a copper reinforced composite pipe with a tri-polypropylene lining. The utility model is characterized in that tri-polypropylene plastic is evenly coated along the circumferential direction and the longitudinal direction of the outer side of a copper tube. An adhesive layer is arranged between the tri-polypropylene plastic and the copper pipe, and the tri-polypropylene plastic and the copper pipe are moulded by the adhesive layer through hot melt bonding and extrusion. The structure formation of the utility model has good strength, high stiffness and small hot deformation. The utility model a reinforced composite pipe which is connected under high temperature and hot melt.
Description
Technical field:
The utility model relates to a kind of composite pipe, relates more specifically to a kind of three type polypropylene copper liner reinforced composite pipes.
Background technique:
Gong Ying random copolymerization propylene (PP-R, PP-C, PP-B) plastic tube in the market, though it is safe and reliable, can be used for the purified water pipe-line system, but under the long-term continuous operation pressure of regulation, when the water temperature of line transportation is high, its resistance to heat distorsion is big, rigidity is relatively poor, makes its using scope be subjected to bigger restriction, and influences the economic benefit of production of articles.
Summary of the invention:
The utility model provides a kind of three type polypropylene copper liner reinforced composite pipes, and it can improve the anti-deformation performance of dimensionally stable under intensity, rigidity and the high temperature of tubing, simple in structurely is beneficial to a large amount of productions, and long service life has higher economical, societal benefits.The technical solution of the utility model is: three type polypropylene copper liner reinforced composite pipes is characterized in that: the circumferential and vertically even coating three type polypropylene plastics on the edge, the outside of copper tube, be equipped with adhesive layer therebetween, and both are through the extruding and moulding of adhesive layer hot melt adhesive.The utility model has overcome the shortcoming of former three type pp pipelines, its resistance to heat is good, and improved mechanical strength, rigidity and dimensional stability and adapted to sweat soldering, making it the life-span improves greatly, this product structure is fairly simple, technology capability well can be produced in a large number, because the expansion that improves corresponding uses of its quality, both can make the producer obtain high economic benefit, can bring the accurate degree of the higher letter of this product for the user again, to the piping erection condition of providing convenience, thereby can accelerate the engineering construction progress, reduce operation labor intensity.
Description of drawings:
Accompanying drawing is an axle side partial schematic sectional view of the present utility model.
Wherein: 1 copper tube, 2 adhesive layers, 3 three type polypropylene plastics
Embodiment:
As shown in drawings: the utility model is circumferential and vertically even coating three type polypropylene plastics 3 on the edge, the outside of copper tube 1, be equipped with adhesive layer 2 therebetween, copper tube 1 and three type polypropylene plastics 3 and adhesive layer 2 are to utilize extrusion shaping machine, through the compound molding of the disposable continuous melt bonding of composite dies, realize industrial-scale production.
The main material of three type polypropylene plastics 3 of the present utility model can be PP-R, PP-C, PP-B, and its thickness is 1-100 times of copper tube 1 pipe thickness, and the main material of copper tube 1 can be to meet having of sanitary standard requirement to stitch or weldless tube.
