Abstract
The utility model provides a steel-plastic high pressure composite pipe with glass fiber enhancement, which belongs to construction field. The medium and low pressure resistant steel-plastic composite pipe is used as a framework; after a plastic layer at the outermost layer is roughened and cleaned with alcohol or ketone, the copulation agent adhesive is painted to form an adhesive layer; then the glass fiber heats the solid resin to continuously twist the adhesive layer, so as to form a glass fiber enhancement layer; finally, a thermoplastic is closely bonded on the glass fiber enhancement layer to form an outer protection layer. The composite pipe can reach the purposes of anti-corrosion, as well as improvement of anti-pressure capacity by a wide margin, which is also provided with excellent corrosion resistance, infiltration-prevention of the plastic pipe, as well as high pressure resistance of the steel tube.
Description
1, technical field: glass fibre enhancing steel of the present utility model is moulded the high pressure composite pipe and is belonged to building field, relates in particular to a kind of bearing pipe.
2, background technique: existing application can anticorrosionly can mainly contain steel pipe, plastic tube, Glass Steel Tube and steel-plastic composite pipe etc. by withstand voltage tubing again.But itself or antiseptic property are unsatisfactory, or voltage endurance capability is limited, or barrier properties is poor.The steel pipe good pressure-resistant performance, but antiseptic property is relatively poor; Though the plastic tube anti-corrosive properties are good, its voltage endurance capability is lower; The Glass Steel Tube anti-corrosive properties are better, but its liner compactness is low, and barrier properties is poor, and its axial modulus of elasticity is little, easily deflection; The anticorrosion resistance to pressure of steel-plastic composite pipe is all better, but will improve its resistance to compression grade, and the necessary corresponding increase of thickness of strips makes steel band moulding difficulty increase thereupon, and die cost increases, thereby steel-plastic composite pipe is mainly used in the mesolow field at present.
3, summary of the invention: the purpose of this utility model is to propose a kind of glass fibre enhancing steel that has good anticorrosion and high voltage performance concurrently and moulds the high pressure composite pipe.
The purpose of this utility model is achieved in that the steel-plastic composite pipe with anti-mesolow is a skeleton, and at first with its outermost plastic layer hacking, after alcohol or ketone cleaning, brushing coupling agent class adhesive on this layer forms sticker layer again; Add thermosetting resin with glass fibre then and twine sticker layer continuously, form glass fiber reinforced layer; At last, on glass fiber reinforced layer again the close adhesion thermoplastic form external protection.
Owing to carry out technique scheme, just can make the steel-plastic composite pipe that has anti-mesolow now reach not only anticorrosion but also increase substantially the purpose of its voltage endurance capability, the utility model just can have the barotolerance of plastic tube superior corrosion resistance, barrier properties and steel pipe concurrently.
4, description of drawings: concrete structure of the present utility model is provided by following drawings and Examples
5, embodiment
Legend: 1, external protection 2, glass fiber reinforced layer 3, sticker layer 4, plastic layer 5, outer adhesive layer 6, steel pipe 7, inner binder layer 8, inner protective layer
Embodiment: as shown in Figure 1, on steel pipe 6 inwalls, apply the MD hot melt adhesive, form inner binder layer 7, form inner protective layer 8 by thermoplastic with inner binder layer 7 close adhesion; Also apply the MD hot melt adhesive on steel pipe 6 outer walls, form outer adhesive layer 5, form plastic layer 4, so, promptly produce the steel-plastic composite pipe of anti-mesolow by thermoplastic with outer adhesive layer 5 close adhesion.With this pipe is skeleton, and at first with its plastic layer 4 hackings, after alcohol or ketone cleaning, brushing coupling agent class adhesive on this layer forms sticker layer 3 again; Add thermosetting resin with glass fibre then and twine sticker layer 3 continuously, form glass fiber reinforced layer 2; At last, the close adhesion thermoplastic forms external protection 1 again on glass fiber reinforced layer 2, and glass fibre enhancing steel is moulded the high pressure composite pipe and promptly be can be made into.
Claims (1)
1, a kind of glass fibre enhancing steel is moulded the high pressure composite pipe, its inwall to outer wall is made up of inner protective layer, inner binder layer, steel pipe, outer adhesive layer, plastic layer, sticker layer, glass fiber reinforced layer and external protection successively, it is characterized in that: be coated with the MD hot melt adhesive on the steel pipe inwall, form the inner binder layer, form inner protective layer by thermoplastic with inner binder layer close adhesion; Also apply the MD hot melt adhesive on the outer wall of steel pipe, form the outer adhesive layer, form plastic layer by the thermoplastic with outer adhesive layer close adhesion, brushing coupling agent class adhesive forms sticker layer on plastic layer; Be wound with the glass fiber reinforced layer that is added with thermosetting resin on the sticker layer continuously; On glass fiber reinforced layer, closely be bonded with the external protection that thermoplastic forms.
