Abstract

The utility model discloses a plastic-based paper composite tube, and particularly relates to a composite tube with plastic sprayed on a metal core rod and with paper serving as stuffing. The plastic-based paper composite tube is characterized in that the plastic which is liquefied in a heated mode is sprayed on a rotating core rod die so that a tube inner cavity can be formed; when the plastic which is liquefied in a heated mode is sprayed on the outer wall of the tube inner cavity, a plastic and paper adhesion body is formed through a paper band with multiple holes; the plastic which is liquefied in a heated mode is sprayed on the outer wall of the plastic and paper adhesion body so that a tube outer wall can be formed. The plastic-based paper composite tube is low in cost, high in intensity and resistant to corrosion. In addition, the plastic serves as base materials of the plastic-based paper composite tube, the paper servers as the stuffing of the plastic-based paper composite tube, and accessories of the plastic-based paper composite tube are universal in current plastic tubes. The plastic-based paper composite tube can be applied to the occasions such as construction water use, farm irrigation, outdoor cable threading, and delivery of gas and liquid and is strong in practicability.

Description

A kind ofly mould basic paper composite pipe

Technical field

The utility model relates to a kind of basic paper composite pipe of moulding, relate in particular to a kind of on metal mandrel plastic-blasting and the composite pipe take paper as filler.

Background technique

The tubing that pipelayer's journey is commonly used at present has seamless steel pipe, black pipe, Coating Steel Pipe, steel to mould pipe, steel porcelain tube, aluminium-plastic pipe, pvc pipe, PPR pipe, PE pipe, rubber pipe, rubber combined pipe etc.If in applications such as construction water, field irrigation, outside cable threading, the tubing of above all kinds, if reach construction requirement, the cost of tubing is all higher.

through the patent searching document, 201210147340.8) and be called " cannon born frame plastic composite pipe and production technology thereof " (application number: application documents 201210146826.X) result for retrieval obtains name and is called " cannon born frame reinforced plastic pipe and production technology thereof " (application number:, all there is necessary prefabricated interior pressure pipe in above two application documents, use steel wire or glass fiber as strengthening net, steel wire or the glass fiber winding of easily tiing a knot when high-speed coiling, make tackiness agent with glue, curing time long the and easy residual harmful substance of glue and harmful volatilization gas, the extruder of pipe must being packed into while making surrounding layer is processed, cause complex process, cost of production rising and manufacturing efficiency are low.

Summary of the invention

The technical problem that the utility model solves is: provide a kind of low cost, high strength, corrosion-resistant, take plastics as base material, take paper as filler, accessory and the general tubing of plastic pipe at present.

The technological scheme of the utility model technical solution problem is:

the utility model discloses a kind of basic paper composite pipe of moulding, comprise inner cavity of pipe, the adherend of plastics and paper, pipeline outer wall, it is characterized in that: inner cavity of pipe has the adherend of plastics and paper outward, the adherend of plastics and paper has pipeline outer wall outward, during production with an end clamping of elongated core rod mould on the chuck of lathe, the movable thimble of lathe tailstock withstands on the other end of core rod mould, then coat releasing agent outside core rod mould, the spraying mouth of spraying equipment is arranged on the knife rest of lathe, after opening lathe, with after heating liquefaction plastic spraying on the surface of core rod mould, control the thickness of spraying plastics according to the feeding speed of lathe, feeding speed is faster, coating thickness is thinner, for the first time after the liquefaction plastic cool of spraying, form inner cavity of pipe at mandrel surface, then the outer wall at inner cavity of pipe sprays for the second time, the paper tape that the surface that with width, is 10mm to 50mm in the time of spraying is covered with regular aperture closely is wrapped in the surface that is coated with plastics liquid, paper tape is with move the simultaneously adherend of rear formation plastics and paper of knife rest, adherend is the spiral stack, the feeding speed of lathe is controlled the thickness that is wound around paper, feeding speed is slower, the adherend of plastics and paper is thicker, to least significant end, block paper, then the outer wall at the adherend of plastics and paper sprays for the third time, form pipeline outer wall after spraying, after cooling, excision pipeline end face out-of-flatness part, according to required length with pipe cutting, take out core rod mould, namely obtain product conduit, the socket joint Component intercommunication of the Component of pipeline and present existing plastic tube.

Principle of the present utility model is:

1, plastics is subjected to hot melt dissolubility matter and rapid curing character when cooling;

2, paper fibre has adsorptive power to the plastics of molten molten state;

3, the plastics in the aperture of paper have improved the Adhesion force on paper two sides;

Key technology of the present utility model is: the tension force appropriateness that spraying is even, paper is wound around, the movement velocity of spraying and paper is even.

Make technology relatively with present patent, the useful technique effect that the utility model is obtained is: cost of production is low, the prices of raw and semifnished materials are low, technique is simple, the pipeline bearing pressure large, and general, the easy realization batch production of pipe fitting, the practicability of the plastic tube of existing other types large.
