Description

A kind of production method of plastic base paper composite pipe

The present invention is the divisional application of patent of invention " a kind of plastic base paper composite pipe ", and the applying date of original application is on May 17th, 2013, and the application number of original application is 2013101817265, and the invention and created name of original application is " a kind of plastic base paper composite pipe ".

Technical field

The present invention relates to the production method of a kind of plastic base paper composite pipe, particularly relate to a kind of on metal mandrel plastic-blasting and be filler with paper the production method of multiple tube.

Background technology

The tubing that pipeline installation engineering 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 tube, rubber combined pipe etc. If in applications such as construction water, field irrigation, outside cable threading, the tubing of all above kind, if reaching construction requirement, the cost of tubing is all higher.

Through patent searching document, retrieval result obtains the application documents that name is called that " cannon born frame reinforced plastic pipe and production technology thereof " (application number: 201210147340.8) and name are called " pipe frame plastic composite pipe and production technology thereof " (application number: 201210146826.X), all there is necessary prefabricated interior pressure pipe in two above application documents, using steel wire or glass fiber as strengthening net, when high-speed coiling, steel wire or glass fiber are easily tied a knot winding, binding agent is done with glue, hardening time length and the easy residual harmful substance of glue and harmful volatilization gas, pipe must be loaded extruding machine when making surrounding layer to be processed, cause complex process, production cost rises and production efficiency is low.

Summary of the invention

Present invention solves the technical problem that and be: provide a kind of low cost, high intensity, corrosion-resistant, with plastics be base material, with paper be filler, accessory and tubing that at present plastic pipe is general.

This invention address that the technical scheme of technical problem is:

The invention discloses a kind of plastic base paper composite pipe, including inner cavity of pipe, the adherend of plastics and paper, pipeline outer wall, it is characterized in that: outside inner cavity of pipe, have the adherend of plastics and paper, pipeline outer wall is had outside the adherend of plastics and paper, during production by one 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 outside core rod mould, coat releasing agent, the spraying mouth of spraying equipment is arranged on the knife rest of lathe, after opening lathe, by after heats liquefied plastic spraying on the surface of core rod mould, feeding speed according to lathe controls the thickness of painted plastic, feeding speed is more fast, coating thickness is more thin, after the liquefied plastics cooling of first time spraying, inner cavity of pipe is formed at mandrel surface, then second time spraying is carried out at the outer wall of inner cavity of pipe, the paper tape that the surface that width is 10mm to 50mm is covered with while spraying rule aperture winds around the surface being coated with plastics liquid, paper tape forms the adherend of plastics and paper with knife rest simultaneously after moving, adherend is superposition helically, the feeding speed of lathe controls to be wound around the thickness of paper, feeding speed is more slow, the adherend of plastics and paper is more thick, to least significant end, block paper, then third time spraying is carried out at the outer wall of plastics and the adherend of paper, pipeline outer wall is formed after spraying, after cooling, excision pipeline end face out-of-flatness part, according to required length by pipe cutting, take out core rod mould, namely finished product pipeline is obtained, the spare and accessory parts of pipeline and the socket joint spare and accessory parts intercommunication of current existing plastic tube.

Principles of the invention is:

1, fast setting character when being subject to hot melt dissolubility matter and cool down of plastics;

2, the plastics of molten molten state are had absorbability by paper fibre;

3, the plastics in the aperture of paper improve the bonding force on paper two sides;

The key technology of the present invention is: the tensile force appropriateness that spraying is uniform, paper is wound around, the movement velocity of spraying and paper is uniform.

Making Technical comparing with current patent, the Advantageous Effects that the present invention obtains is: production cost is low, the prices of raw materials are low, technique is simple, pipeline bearing pressure big and the realization general, easy of the pipe fitting of existing other kinds of plastic tube is produced in batches, practicality is big.
