Description
Technical field
The present invention relates to mould, more particularly to a kind of continuous fiber cloth or the multi-layer co-extruded extrusion die of fiber cloth set.
Background technology
With the continuous development of society, obtain the advantages of plastic pipe is by light weight, corrosion-resistant, long service life
Extensively application.But compared with traditional piping material (such as pipe of concrete), plastic pipe has that quality is soft, machinery
The defect such as low intensity, easy creep and stress relaxation destruction, poor dimensional stability.These weak points greatly limit
The popularization of plastic pipe and application.Fiber has the features such as intensity is high, wear-resisting, corrosion-resistant, resistance to impact is good, because
This enhancing for being commonly used for plastic pipe is modified.At present, most of fibre reinforced plastic tube materials still adopt " zero dimension "
Chopped fiber is modified, few to be strengthened using " one-dimensional " continuous tow, there is not yet relevant ripe " two dimension "
Fiber cloth strengthens the report of modified plastics tubing.
Patent of invention CN102011897A is reported " a kind of fiber reinforced pipe and its production method for mine ".
The elementary production steps of the fiber reinforced pipe referred in patent are as follows：Melting charge is extruded by extrusion die first,
Pass sequentially through Vacuum shaping, be cooled into polyethylene liner pipe；It is uniform in the braiding of internal lining pipe outer peripheral face with wrapping machine again
The winding fiber of intersection, forms fiber-reinforced layer；Outer layer is extruded finally by extruder and be coated on the fibrage
Outer peripheral face, forms multi-layer compound structure.But this production method has the disadvantage that：(1) complex production process,
Post-forming process need to be carried out, efficiency is low；(2) extruder and wrapping machine need to be simultaneously equipped with, equipment investment is high；(3)
Using post forming and establishment winding, fiber is low with the bonding strength of interlaminar resin, easily peeling-off；(4) product office
It is sex-limited, it is impossible to be applied on plastic tubing of hollow structural wall, particularly I-shaped die, ripple type, cyclic rib type etc.
Structure-wall pipe material.
Patent of invention CN102604410A is reported " glass fibre reinforced composion ".One is referred in patent
Plant the production method of epoxy fiberglass tubes.Production stage includes：(1) according to percentage by weight take glass fibre, resin and
Relevant auxiliary agent；(2) after being sufficiently mixed resin and auxiliary agent uniformly, add glass fibre and fully infiltrate：(3) will
Compound adds mould aftershaping, solidification.But there are the following problems for the fiberglass tubes produced by the production technology：
Complex manufacturing, high cost；Repeatedly machine-shaping, production efficiency is low；Agents useful for same contaminative is big；Using
Chopped fiber is modified, and is only capable of improving the intensity of tubing to a certain extent, but cannot effectively improve the tough of tubing
Property and impact energy.
Plastics are carried out using " zero dimension " material-chopped fiber strengthen modified, although have one to the mechanical strength of tubing
Determine the raising of degree, but it is limited to lift effect.This is because enhancing effect has close association with the length of fiber.
Because chopped fiber shows as isotropism in matrix resin, it is impossible to improve the toughness of tubing.Using " one-dimensional " material
- continuous tow is modified the tubing for obtaining to tubing is only having preferable tensile property along Direction of fibre distribution
And still lack restraining force in remaining direction, particularly it is also easy to produce stripping between fibre bundle and resin when exposed to external forces.
