Abstract
The present invention discloses a kind of graphite modified polypropylene pipe, described graphite modified polypropylene pipe includes PA tube main body, the PA tube body outer wall sets gradually 150 250 μm of epoxide powder coating layer and 450 550 μm of polyethylene powder coating layer, the PA tube main body is made up of conductive carbon fibre, fiber glass reinforced polypropylene, described conductive carbon fibre accounts for 30% the 40% of PA tube main body totality component, and described fiber glass reinforced polypropylene accounts for 60% the 70% of PA tube main body totality component.The present invention provides a kind of graphite modified polypropylene pipe, has the advantages of resistance to elevated temperatures is good, antiseptic effect is lasting.
Description
Technical field
The present invention relates to a kind of graphite modified polypropylene pipe.
Background technology
Anti-corrosion measure for pipe outer surface at present is typically all directly to be coated on anti-corrosion material outside tubing or straight
Spray paint or other anticorrosive coats are connect, the major defect for directly coating anti-corrosion material is the poor adhesive force of anti-corrosion material, easily de-
Fall, anti-corrosion is not lasting, is anticorrosive coat thickness low LCL, anticorrosive coat rapid wear the shortcomings that right direct spraying paint or other anticorrosive coats
Consumption, it is impossible to lasting anti-corrosion, while the resistant to elevated temperatures performance of both corrosion-resistant is all relatively poor.
The content of the invention
The present invention, which provides, a kind of has that resistance to elevated temperatures is good, the graphite modified polypropylene pipe of the lasting advantage of antiseptic effect.
The technical scheme is that：A kind of graphite modified polypropylene pipe, described graphite modified polypropylene pipe include poly-
Acrylic tubing main body, the PA tube body outer wall set gradually 150-250 μm epoxide powder coating layer and 450-550 μm
Polyethylene powder coating layer, the PA tube main body are made up of conductive carbon fibre, fiber glass reinforced polypropylene, described conduction
Carbon fiber accounts for the 30%-40% of PA tube main body totality component, and described fiber glass reinforced polypropylene accounts for PA tube main body totality
The 60%-70% of component.
In a preferred embodiment of the present invention, the PA tube inner major diameter is 1.2-1.6m.
In a preferred embodiment of the present invention, the PA tube body thickness is 14-20mm.
A kind of graphite modified polypropylene pipe of the present invention, there is the advantages of resistance to elevated temperatures is good, antiseptic effect is lasting.
Embodiment
Presently preferred embodiments of the present invention is described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly defined so as to be made to protection scope of the present invention.
Wherein, described graphite modified polypropylene pipe includes PA tube main body, and the PA tube body outer wall is successively
150-250 μm of epoxide powder coating layer and 450-550 μm of polyethylene powder coating layer is set, and the PA tube main body is
It is made up of conductive carbon fibre, fiber glass reinforced polypropylene, described conductive carbon fibre accounts for the 30%- of PA tube main body totality component
40%, described fiber glass reinforced polypropylene accounts for the 60%-70% of PA tube main body totality component.
Further illustrate, the PA tube inner major diameter is 1.2-1.6m, and the PA tube body thickness is 14-
20mm。
Further illustrate, with coating even compact coated on the metallic conduit surface through derusting, make itself and various corruption
Corrosion medium completely cuts off, and is one of most basic method of pipeline corrosion protection.Therefore, anticorrosion coating on pipeline uses composite wood more and more
Material or composite construction.Outer wall corrosion-inhibiting coating：Pipeline outer wall coating material species and use condition.Inner wall anti-corrosive coating：In order to anti-
Only tube inner corrosion, reduce frictional resistance, improve throughput rate and be applied to the film of tube wall.Conventional coating has amine cured epoxy tree
Fat and Polyamide Epoxy, coating layer thickness are 0.038~0.2 millimeter.To ensure that coating is firmly bonded with tube wall, it is necessary to right
Inside pipe wall is surface-treated.The inside and outside wall coating of pipe it has been intended to since the seventies and selects identical material, so as to the inside and outside wall of pipe
Coating carry out simultaneously.Corrosion-resistant thermal insulation coating：In, on the pipeline of small-bore hot output oil or fuel oil, in order to reduce pipe
Road radiates to soil, in pipeline external plus insulation and corrosion-resistant composite bed.Conventional insulation material is hard polyurethane fat vacuole foam
Plastics, Applicable temperature are -185~95 DEG C.This texture material is soft, outside thermal insulation layer plus deposited one layer to improve its intensity
High-density polyethylene layer, composite structure is formed, to prevent in Groundwater infiltration heat-insulation layer.The present invention provides a kind of graphite and changed
Property PA tube, there is the advantages of resistance to elevated temperatures is good, antiseptic effect is lasting.
The embodiment of the present invention, but protection scope of the present invention is not limited thereto, any to be familiar with this area
Technical staff disclosed herein technical scope in, the change or replacement that can expect without creative work should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be with protection model that claims are limited
Enclose and be defined.
