Abstract
The utility model aims to solve the problems by providing a short fiber reinforced polyethylene compound pipe comprising an outer pipe, a reinforcing layer and an inner pipe. The outer pipe is connected with the reinforcing layer through an outer pipe connecting layer. The inner pipe is connected with the reinforcing layer through an inner pipe connecting layer. The short fiber reinforced polyethylene compound pipe is characterized in that the reinforcing layer is made of wire mesh, wire frame or fiber mesh; a short fiber frame is disposed in the outer pipe and the inner pipe; both the outer pipe and the inner pipe are PE pipes; short fiber for the short fiber frame in the outer pipe and the inner pipe is glass fiber or carbon fiber; any of the glass fiber and carbon fiber is not larger than 1.2mm in length. The fiber mesh is high-strength fiber mesh made of high-strength fiber or made of flat fiber tapes made from high-strength fiber. The short fiber reinforced polyethylene compound pipe has the advantages that tensile resistance of the pipe is improved, especially the axial and circumferential tensile resistance in the outer pipe and the inner pipe is improved, the reinforcing layer between the inner pipe and the outer pipe is protected from being corroded by liquid or soil conveyed in the pipe.
Description
Technical field
The utility model relates to tubing manufacturing technology field, relates in particular to a kind of short fibre enhanced polyethylene composite pipe.
Background technique
Steel wire mesh frame (Steel Skeleton) polyethylene compound pipe is take the Wrapping formed mesh skeleton of high-tensile steel wires left-and-right spiral as reinforcement, take high density polyethylene (HDPE) (HDPE) as matrix, and a kind of novel tube steel-wire carcass and inside and outside hdpe layer closely being linked together with high performance HDPE modification binding resin.Because high-tensile steel wires reinforcement is covered by among continuous thermoplastic plastics, therefore steel wire mesh frame (Steel Skeleton) polyethylene compound pipe has overcome steel pipe and plastic tube shortcoming separately, and has kept steel pipe and plastic tube advantage separately.
Steel wire mesh frame (Steel Skeleton) polyethylene compound pipe, has adopted the material of high-quality and advanced production technology, makes it to have higher withstand voltage properties.Meanwhile, this composite pipe has good flexibility, is applicable to long distance buried with water supply, Gas pipeline system.The pipe fitting that steel wire mesh frame (Steel Skeleton) polyethylene compound pipe adopts is polyethylene fused pipe.When connection, utilize inside pipe fitting heater by tubing outer layer plastic and the melting of pipe fitting inner plastic, tubing and pipe fitting are linked together reliably.Use high density polyethylene (HDPE) (HDPE), strong steel wire spiral is wound around framework and creates high tensile strength, to strengthen health.Use high density polyethylene (HDPE) (HDPE) as the result of raw material the pipe arrangement at a lightweight, resisting aggression property chemical product, can bear freeze thawing circulation and continue subzero temperature, does not ftracture.HDPE is high wear resistance, is acid and alkali degree or basicity.But not to be also all-fus HDPE have very strong steel wire and a lightweight for this, and pipe obtains higher tensile strength and durability flexibly.The most important thing is, special electric melting pipe fittings cheaply, the connection of pipeline enclosure, installs fault-free and does not still give a discount.Due to these speciality, SRTP pipe is often used in town water supply, civil engineering, oil and natural gas field, chemical industry, electric power transfer pipeline, metallurgical mine, seawater transportation, shipbuilding, agricultural and laying fiber optic cables.
Its structure of steel wire mesh frame of the prior art (Steel Skeleton) polyethylene compound pipe is made up of outer tube, enhancement layer (steel wire or Steel Skeleton) and core pipe.Its middle external tube and core pipe are mainly made up of PE.This tubing is axially having good stretch-proof performance, for hoop or other composite squares to intensity not good, although enhancement layer itself can provide certain hoop tensile strength, but still do not address this problem for outer tube and inner tube itself.
Short fiber, claims again staple fiber.Chemical fibre long-fiber bundle is cut off or breaks into the fiber that is equivalent to various natural fibre length.Also can be with natural fibre as whisker and asbestos.Short fibre boundary, length is generally 35～150mm.Can be divided into cotton type, wool type, the short fibres such as type carpet and medium length type by the specification of natural fibre.They can purely spin, and also can make sliver, fabric and felt with the natural fibre of different proportion or other fiber blends.
For example, general purpose grade asphalt-based carbon fiber is cut into 150mm long, diameter is 15 μ m, intensity is 800MPa, and the carbon fiber of modulus 41GPa, with phenolic aldehyde based carbon fiber (length 70mm, intensity 200MPa, diameter 14 μ m) mix with the ratio of 8:2, make the sliver of stablizing expansion.Be woven into various shapes fabric or short be cut into fiber for composite material as the reinforcement of cement, aluminum alloy.
Model utility content
Problem to be solved in the utility model is: a kind of short fibre enhanced polyethylene composite pipe is provided.
The technical solution of the utility model is as follows: a kind of short fibre enhanced polyethylene composite pipe, comprise outer tube, enhancement layer and core pipe, between described outer tube and enhancement layer, connect by outer tube binder course, between described core pipe and enhancement layer, connect by core pipe binder course, it is characterized in that:
Described enhancement layer is steel wire, Steel Skeleton or fleece;
In described outer tube and core pipe, be provided with short fibre skeleton.
Further, described outer tube and core pipe are PE pipe, and the short fibre of its inner short fibre skeleton is glass fibre or carbon fiber, and arbitrary its length is not more than 1.2mm.
Further, described fleece is high strength fibre net, and it is for by high strength fibre silk or the flat fiber band be made up of high strength fibre.
Further again, described high strength fibre is aramid fibre.
Further, described outer tube binder course and core pipe binder course are PE modified hot melt adhesive or medium density polyethylene or epoxy resin.
The beneficial effects of the utility model are: the stretch-proof performance that has improved tubing by the utility model short fibre enhanced polyethylene composite pipe; especially improved its outer tube and core pipe itself and risen performance for the tension of axial and hoop, and then liquid or the soil of protecting the enhancement layer being clipped in the middle can in tubing, do not carried corrode.
