Abstract
The utility model relates to a composite plastic pipeline, which comprises a plastic pipeline basement layer, wherein a plastic/glass fiber fabric mixing layer, a glass fiber reinforced plastics layer and an external protection layer are sequentially composited outside the plastic pipeline basement layer. In the composite plastic pipeline, the plastic/glass fiber fabric mixing layer, the glass fiber reinforced plastics layer and the external protection layer are sequentially composited outside the polypropylene plastics pipeline, the plastic/glass fiber fabric mixing layer tightly connects and composites the plastic pipeline basement layer and the glass fiber reinforced plastics layer which has good corrosion resistance and ageing resistance, high strength and high heat resistance, so the glass fiber reinforced plastics materials are composited outside the polypropylene plastics pipe. Accordingly, the service life of the plastic pipeline is prolonged, and the plastic pipeline has the characteristics of high heat resistance, good ageing resistance, stable corrosion resistance and uneasy deformation.
Description
Technical field
The utility model relates to a kind of composite plastic pipe, relates in particular to a kind of anti-ultraviolet composite plastic pipe.
Background technique
Be used to carry potable water, chemicals etc. to have the more employing polypropylene plastics of the pipeline pipeline of Korrosionsmedium at present.Advantages such as that though this pipeline possesses is nontoxic, corrosion-resistant, in light weight, liquid resistance is little, the problem that polypropylene pipe ubiquity ageing resistance is poor, working pressure is low, pipeline is yielding, working life is relatively short.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of have high-fire resistance, multiple tube not yielding, that aging quality resistance is good, stable, the long service life of antiseptic property.
In order to address the above problem, the technical solution of the utility model is:
A kind of composite plastic pipe comprises plastic pipe basic unit, is compounded with plastics/glass cloth mixing layer, frp layer and external protection successively outside the described plastic pipe basic unit.
The material of described plastic pipe basic unit is a polypropylene pipe basic unit; described plastics/glass cloth mixing layer is the mixing layer that forms at the outside hot pressing glass cloth of polypropylene pipe basic unit; described frp layer is formed by unsaturated polyester resin and glass yarn, the curing of glass cloth, and described external protection is to be solidified by ultraviolet protecting agent and gel coating resin to form.
Preferably, described frp layer thickness is 2.5～7mm.
Preferably, described external protection thickness is 0.2～0.25mm.
The composite plastic pipe that the utility model provides is outside compound plastics/glass cloth mixing layer, frp layer and the external protection at the polypropylene plastics pipeline; plastics/glass cloth mixing layer is with plastic pipe basic unit and have good corrosion, ageing resistance; high strength, high heat-resisting frp layer closely connect compound; glass fibre reinforced plastic material is compounded in outside the pp pipeline; thereby increased the working life of plastic pipe, make plastic pipe have heat resistance height, aging quality resistance good, stable, the on-deformable characteristics of antiseptic property.
Description of drawings
Fig. 1 is the lateral cross section sectional view of the utility model composite plastic pipe.
Fig. 2 is the axial sectional view of the utility model composite plastic pipe.
Embodiment
Further describe the utility model below in conjunction with drawings and Examples, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1-2; composite plastic pipe of the present utility model is composited for 4 four layers by plastic pipe basic unit 1, plastics/glass cloth mixing layer 2, frp layer 3 and external protection, plastic pipe basic unit 1 outer compound successively plastics/glass cloth mixing layer 2, frp layer 3 and external protection 4.
The material of described plastic pipe basic unit 1 is a polypropylene pipe basic unit.Described plastics/glass cloth mixing layer 2 is the mixing layers that form at the outside hot pressing glass cloth of polypropylene pipe basic unit 1, concrete mode is: surface contaminants is removed with acetone and other organic solvent in the surface in polypropylene pipe basic unit 1, the back makes the surface melting of polypropylene pipe basic unit greater than 3000 ℃ high temperature spray gun with flame temperature, simultaneously with glass cloth compacting and with the polypropylene pipe substrate surface fusion of fusion, glass cloth space is filled up by polypropylene thermal is tolerant.Described frp layer 3 is to make it soak into glass cloth fully at plastics/glass cloth mixing layer 2 external coating resins, makes frp layer 3 and plastics/glass cloth mixing layer 2 closely compound; Frp layer 3 is by unsaturated polyester resin and glass yarn or glass twines yarn, the curing of glass cloth forms, and the thickness of frp layer 3 can be determined that general thickness is 2.5～7mm by the working pressure and the temperature of pipeline.Described external protection 4 is to apply the gel coating resin that one deck contains ultraviolet protecting agent outside frp layer 3, and solidifying, and the thickness of external protection 4 is 0.2～0.25mm.
Claims (3)
1. a composite plastic pipe comprises plastic pipe basic unit, it is characterized in that, is compounded with plastics/glass cloth mixing layer, frp layer and external protection successively outside the described plastic pipe basic unit.
2. composite plastic pipe according to claim 1 is characterized in that, described frp layer thickness is 2.5～7mm.
