Abstract
The invention discloses a kind of composite pipe, comprise steel pipe, the coated ultra-high molecular weight polyethylene layer in described steel pipe periphery, adhesive layer is provided with between described steel pipe and described ultra-high molecular weight polyethylene layer, adhesive layer is formed by the adhesive applied, described adhesive is by rubber, butadiene-styrene rubber, Ludox, fire clay, pitch, rosin, silica, zinc oxide, water and diethylenetriamine, and the present invention has good UV resistant and nuclear radiation, pliability and excellent wear-resisting, durability.This adhesive compatibility is good, and normal temperature self-drying is nonpoisonous and tasteless, strong adhesion.
Description
Technical field
The present invention relates to a kind of composite pipe, belong to tubing technical field.
Background technology
Current numerous domestic conveying machinery industry carrying roller used has outside steel pipe, nylon tube, steel and covers the kind such as rubber tube, steel sleeve PE pipe, simple use steel pipe do carrying roller exist easily get rusty, frictional resistance is large and to defects such as conveyer belt serious wear; And using nylon tube to make carrying roller, production length within 500mm, once lengthen, can only can not carry larger load; Although it is better to cover rubber elasticity outside steel pipe, there is the defect that frictional resistance is large equally; And use steel pipe overcoat polyvinyl piping materials, although interference fit can be adopted to make to reduce gap between steel pipe and the polyethylene pipe of overcoat when assembling, but due to certain heat can be produced in running after friction, and polyethylene cannula external diameter after being heated expands, thus there is skidding, be subject to certain impact service life.In order to solve the adhesion problem, in prior art, adopt the method increasing adhesive, but due to tubing environment for use, there is larger corrosivity and especially in the north of cold, still come off after using a period of time.
Summary of the invention
The object of the invention is to overcome defect of the prior art, provide a kind of
composite pipe, this this tubing has good weatherability, and cohesive is good.
The present invention is achieved by the following technical programs.
A kind of composite pipe, comprises steel pipe, the coated ultra-high molecular weight polyethylene layer in described steel pipe periphery, be provided with adhesive layer between described steel pipe and described ultra-high molecular weight polyethylene layer, adhesive layer is formed by the adhesive applied, wherein, described adhesive is made up of following ingredients, by weight:
Rubber 90-100 part
