Abstract
The invention discloses a plastic composite pipe, which is characterized in that the plastic composite pipe uses a basalt fiber as a reinforcement, and is made by compounding a plurality of layers of plastics, and two adjacent pipe layers are connected through adhesives; and the composite pipe is made by sequentially compounding an inner layer plastic layer, a basalt fiber layer, a hot melt adhesive layer and an outer layer plastic layer, and the inner layer plastic layer adopts high temperature resistant crosslinking polyethylene or polyethylene. The plastic composite pipe has the advantages of high intensity, high temperature resistance, low temperature resistance, good hot melt performance, and good promotional value.
Description
Technical field
The present invention relates to the composite pipe technical field, more particularly relate to a kind of plastic composite pipe.
Background technique
At present, the compound plastic composite pipe kind of thermoplastic that occurs on the market and metal frame is varied, they have all brought into play very big effect to the enhancing of plastic tube with to the corrosion-resisting function of metal tubes such as steel pipe, particularly the composite pipe of the cylindrical skeleton of winding of plastics and steel wire or braided steel wire formation has become suitable industry.As Chinese patent application number is 02133608.3, the applying date is on August 15th, 2002, denomination of invention is the non-cross-linking refractory polyethylene plastic composite pipe that metal frame strengthens, it is characterized in that composite pipe tube wall continuum material is a non-cross-linking refractory polyethylene, the pertusate steel plate that is coated with web frame with holes in continuum rolls welding or broadwise steel wire twines the tubular metal welding of warp-wise steel wire or that spiral twines or braided steel wire forms and strengthens the body skeleton.The composite pipe of this structure has the performance of good high temperature resistant, low temperature, environment stress cracking, but because the magnification of metal and plastics exists than big-difference, composite pipe is in expansion and contraction process, metal strengthens the body skeleton to be separated easily with plastics, influences the life-span and stability of pipeline greatly.For this reason, at the variety of issue that prior art exists, provide a kind of can be on the intensity based of reinforced plastic pipe, the problem that the novel tube that does not influence the internal structure of composite pipe has again become people to be inquired into.
Summary of the invention
Purpose of the present invention is exactly a kind of not only high temperature resistant, the low temperature that provides for the deficiency that solves prior art, and hot melt is good, intensity height, and the stable plastic composite pipe of internal structure.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of plastic composite pipe is characterized in that: it be with basalt fibre as strengthening body, be composited by the several layers plastics, connect by hot melt adhesive between the two adjacent pipe layer materials.
As further specifying of such scheme, described composite pipe is composited by inner plastic, basalt fibre layer, heat-fusing glue layer and outer layer plastic layer successively, and the inner plastic layer adopts high temperature resistant crosslinked polyethylene or polyethylene.
That described basalt fibre layer is is netted, helical or longitude and latitude shape.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
The present invention adopts basalt fibre as strengthening body, substitute wire netting skeleton of the prior art, because the magnification of basalt fibre and internal and external layer plastic layer is close, so composite pipe is in thermal expansion or cold contraction process, interconnective two layers of material all keeps combination closely, can satisfy requirement of strength on the one hand, can prolong the working life of composite pipe on the other hand, strengthen its stability and Security, this be in the market plastic composite pipe can not compare, also be the insoluble problem of composite pipe that all the time adopts the metal frame structure.

Description of reference numerals: 1, basalt fibre layer 2, plastic layer 3, hot melt adhesive
Embodiment
As shown in Figure 1 and Figure 2, a kind of plastic composite pipe of the present invention, it is as strengthening body with basalt fibre 1, be composited by several layers plastic layer 2, connect by hot melt adhesive 3 between the two adjacent pipe layers, in the present embodiment, composite pipe is composited by inner plastic, basalt fibre layer, heat-fusing glue layer and outer layer plastic layer successively, the inner plastic layer adopts high temperature resistant crosslinked polyethylene or polyethylene, and basalt fibre 1 is netted, with the thickness of plastic layer than being 1:1.5.
The present invention adopts basalt fibre as strengthening body, substitute wire netting skeleton of the prior art, because the magnification of basalt fibre and internal and external layer plastic layer is close, so composite pipe is in thermal expansion or cold contraction process, interconnective two layers of material all keeps combination closely, this be in the market plastic composite pipe can not compare, also be the problem that all the time adopts the metal frame structure to be difficult to overcome as the tubing that strengthens the composite pipe strength structure.
As previously discussed, it only is preferred embodiment of the present invention, can not limit the present invention's interest field with this, described basalt fibre 1 can also be set to other shape, as helical, longitude and latitude shape etc., therefore the equivalent variations of being done according to the present patent application claim still belongs to the scope that the present invention is contained.
Claims (3)
1, a kind of plastic composite pipe is characterized in that: it be with basalt fibre as strengthening body, be composited by the several layers plastics, connect by hot melt adhesive between the two adjacent pipe layers.
2, plastic composite pipe according to claim 1 is characterized in that: described composite pipe is composited by inner plastic, basalt fibre layer, heat-fusing glue layer and outer layer plastic layer successively, and the inner plastic layer adopts high temperature resistant crosslinked polyethylene or polyethylene.
