Abstract
The invention discloses a method for preparing a composite pipe and belongs to the technical field of pipes. According to the method, the outer surface of a steel pipe is uniformly coated with a layer of vinylidene chloride adhesive, and the steel pipe is coated with a polyethylene layer with an ultra-high molecular weight through extrusion, so that the polyethylene layer with the ultra-high molecular weight is tightly combined with the steel pipe, skidding and stripping phenomena are avoided, and the service life of the pipe is greatly prolonged. The pipe prepared with the method has the advantages of resistance to abrasion, low probability of stripping, high shock strength and the like.
Description
Technical field
The present invention relates to a kind of preparation method of composite pipe, belong to the tubing technical field.
Background technology
At present the used carrying roller of numerous domestic conveying machinery industry 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 defectives such as conveyer belt serious wear; And use nylon tube to make carrying roller, production length can only be within 500mm, in case lengthen then can not carry larger load; Although it is better that steel pipe covers rubber elasticity outward, there is equally the large defective of frictional resistance; And use steel pipe overcoat polyvinyl piping materials, reduce the gap although can adopt interference fit to make between the polyethylene pipe of steel pipe and overcoat in when assembling, but owing in running, producing certain heat through meeting after the friction, and polyethylene cannula external diameter after being heated expands, thereby skidding occurs, be subject to certain impact service life.
Summary of the invention
The object of the invention is to overcome defective of the prior art, a kind of preparation method of composite pipe is provided, that the tubing of described method preparation has is wear-resisting, be difficult for peeling off and the characteristic such as impact strength height.
The present invention is achieved by the following technical programs.
A kind of preparation method of composite pipe, the preparation method is as follows: at first outer surface of steel tube is carried out derusting by sandblasting, the outer surface of steel tube cleaning is clean, evenly apply one deck chlorinated polyvinyl chloride bonding agent at outer surface of steel tube again, then will be coated with the steel pipe at room temperature dry 20-30 minute of binding agent, again steel pipe is inserted in the mould, open extruder at steel pipe outer cladding one deck ultra-high molecular weight polyethylene layer, the heating-up temperature of respectively distinguishing of extruder is followed successively by 165 ℃, 170 ℃, 170 ℃, 175 ℃, 180 ℃, 190 ℃, die temperature is 185-190 ℃, extruder main frame rotating speed is 400-450r/min, gets final product finally by the water tank cooling.
The preparation method of above-mentioned a kind of composite pipe, wherein, the thickness of described ultra-high molecular weight polyethylene layer is 8-12mm.
The preparation method of above-mentioned a kind of composite pipe, wherein, with the steel pipe that was coated with binding agent at room temperature dry 25 minutes.
The method of the invention is because employing evenly applies one deck chlorinated polyvinyl chloride bonding agent at outer surface of steel tube, then outside steel pipe, extrude again the method that coats one deck ultra-high molecular weight polyethylene layer, so that ultra-high molecular weight polyethylene and steel pipe are combined closely, thereby the peeling of skidding can not occur, greatly prolong the service life of tubing.That the composite pipe that described method is prepared has is wear-resisting, be difficult for peeling off and the characteristics such as impact strength height.
