Abstract
The invention discloses a composite pipe, comprising a steel pipe, wherein an ultrahigh molecular weight polyethylene layer is coated on the periphery of the steel pipe, a bonding layer is arranged between the steel pipe and the ultrahigh molecular weight polyethylene layer, the bonding layer is formed by coating an adhesive, and the adhesive is made of raw rubber, butadiene styrene rubber, silica sol, fire clay, asphalt, rosin, silica, zinc oxide, water and diethylenetriamine. The invention has good ultraviolet ray resistance, nucleus radiation resistance, good flexibility, excellent wear resistance and excellent endurance. The adhesive has advantages of good compatibility, self-drying at normal temperature, no toxin, no flavor and strong adhesive force.
Description
Technical field
The present invention relates to a kind of composite pipe, belong to tubing technical field.
Background technology
At present numerous domestic conveying machinery industry carrying roller used has steel pipe, nylon tube, steel to cover the kinds such as rubber tube, steel sleeve PE pipe outward, use merely steel pipe do carrying roller exist easily get rusty, frictional resistance is greatly with to defects such as conveyer belt serious wear; And use nylon tube to make carrying roller, production length can only, within 500mm, once lengthen, can not be carried larger load; Although it is better that steel pipe covers rubber elasticity outward, there is equally the defect that frictional resistance is large; And use steel pipe overcoat polyvinyl piping materials, although can adopt interference fit to make to reduce gap between steel pipe and the polyethylene pipe of overcoat when assembling, but owing to can produce certain heat after friction in running, and polyethylene cannula external diameter after being heated expands, thereby there is skidding, be subject to certain impact service life.In order to solve the adhesion problem, available technology adopting increases the method for adhesive, but because tubing environment for use has larger corrosivity and special in the cold north, after use a period of time, still comes off.
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 composite pipe, comprises steel pipe, and described steel pipe periphery is coated ultra-high molecular weight polyethylene layer, between described steel pipe and described ultra-high molecular weight polyethylene layer, be provided with adhesive layer, adhesive layer is formed by the adhesive applying, wherein, described adhesive is comprised of following ingredients, by weight:
Rubber 90-100 part
5～13 parts, butadiene-styrene rubber
Ludox 15-20 part
20 parts of fire clays
10 parts of pitches
10 parts of rosin
