Description
Technical field
The utility model relates to mould, particularly relates to a kind of continuous fiber cloth or fiber cloth overlaps multi-layer co-extruded extrusion die.
Background technology
Along with the development of society, plastic pipe relies on the advantages such as quality is light, corrosion-resistant, long service life to be used widely.But compared with traditional piping material (as pipe of concrete etc.), plastic pipe also exists that quality is soft, mechanical strength is low, the defect such as easy creep and stress relaxation destruction, poor dimensional stability.These weak points greatly limit the propagation and employment of plastic pipe.Fiber has the features such as intensity is high, wear-resisting, corrosion-resistant, resistance to impact is good, is therefore often used to the enhancing modification of plastic pipe.At present, most of fibre reinforced plastic tube material still adopts " zero dimension " short fiber to carry out modification, and few " one dimension " continuous tow that adopts strengthens, and there is not yet the report that relevant ripe " two dimension " fiber cloth strengthens modified plastics tubing.
Patent of invention CN102011897A reports " a kind of fiber reinforced pipe for mine and production method thereof ".The elementary production steps of the fiber reinforced pipe mentioned in patent is as follows: first extruded by extrusion die by melting charge, forms polyethylene liner pipe successively by Vacuum shaping, cooling; Again with the winding fiber of wrapping machine at internal lining pipe outer peripheral face braiding uniform crossover, form fiber-reinforced layer; Extrude skin finally by extruder and be coated on described fibrage outer peripheral face, forming multi-layer compound structure.But this production method exists following shortcoming: (1) complex production process, need carry out post-forming process, efficiency is low; (2) need be equipped with extruder and wrapping machine, equipment investment is high simultaneously; (3) adopt post forming to be wound around with establishment, the bonding strength of fiber and interlaminar resin is low, easily peels off; (4) product limitation, cannot be applied on plastic tubing of hollow structural wall, particularly the structure-wall pipe material such as I-shaped die, ripple type, cyclic rib type.
Patent of invention CN102604410A reports " glass fibre reinforced composion ".A kind of production method of epoxy fiberglass tubes is referred in patent.Production stage comprises: (1) gets glass fibre, resin and relevant auxiliary agent according to percentage by weight; (2) after resin and auxiliary agent fully being mixed, then add glass fibre and fully infiltrate: compound is added mould aftershaping, solidification by (3).But there are the following problems for the fiberglass tubes of being produced by this production technology: complex manufacturing, and cost is high; Repeatedly machine-shaping, production efficiency is low; Agents useful for same contaminative is large; Adopt short fiber to carry out modification, only can improve the intensity of tubing to a certain extent, but effectively cannot improve toughness and the high-impact performance of tubing.
Adopt " zero dimension " material-short fiber to carry out enhancing modification to plastics, although be improved to some extent to the mechanical strength of tubing, promote limited efficiency.This is because the length strengthening effect and fiber has close association.Because short fiber shows as isotropism in matrix resin, the toughness of tubing cannot be improved.Adopting " one dimension " material-continuous tow to carry out tubing that modification obtains only still lacking restraining force in all the other directions along Direction of fibre distribution there being good tensile property to tubing, being particularly easily peeling between fibre bundle and resin when exposed to external forces.
