Abstract
The utility model relates to a high-pressure-resistant glass fiber reinforced plastic reinforced steel-plastic pipe, which belongs to the building field. A composite steel-plastic pipe resisting the medium pressure and the low pressure is adopted as a skeleton, after a plastic layer on the most outer layer of the skeleton is polished and washed by alcohol or ketone, a coupling-agent-type caking agent is then coated on the plastic layer to form a bond layer, and then glass fiber which is immersed with resin is used for winding the bond layer to form a glass fiber reinforced plastic reinforced layer; and finally thermoplastic plastics is closely adhered onto the glass fiber reinforced plastic reinforced layer to form an outer protecting layer. The composite pipe not only can realize the corrosion resistance, but also can greatly improve the pressure resistance, and simultaneously has the excellent corrosion resistance and permeability prevention of a plastic pipe and the high pressure resistance of a steel pipe.
Description
Technical field
High pressure resistant glass fibre reinforced plastics enhancing steel of the present utility model is moulded pipe and is belonged to building field, relates in particular to a kind of bearing pipe.
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 antiseptic property is 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; Just the anticorrosion resistance to pressure of plastic composite 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 the grinding tool expense increases, thereby steel-plastic composite pipe is mainly used in low-pressure field at present.
Summary of the invention
The purpose of this utility model is to propose a kind of high pressure resistant glass fibre reinforced plastics enhancing steel that has good anticorrosion and high voltage performance concurrently and moulds pipe.
The object of the present invention is achieved like this: apply on the steel pipe inwall by the MD hot melt adhesive, adhesive layer in forming forms inner protective layer by the 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; Twine the glass fiber reinforced layer of heat of emersion thermosetting resin on the tackiness agent continuously; The external protection that close adhesion is formed by thermoplastic on glass fiber reinforced layer.
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.
Description of drawings
Concrete structure of the present utility model is provided by the following drawings and embodiment
Accompanying drawing 1 is that high pressure resistant glass fibre reinforced plastics strengthens the sectional drawing that steel is moulded pipe
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, can 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; Soak into thermosetting resin with glass fibre then and twine sticker layer 3, form glass fiber reinforced layer 2; At last, the external protection 1 that forms of close adhesion thermoplastic again on glass fiber reinforced layer 2, high pressure resistant glass fibre reinforced plastics strengthen steel and mould pipe and promptly can be made into.
Claims (1)
1. a high pressure resistant glass fibre reinforced plastics enhancing steel is moulded 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: apply on the steel pipe inwall by the MD hot melt adhesive, adhesive layer in forming forms inner protective layer by the 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; Twine the glass fiber reinforced layer of heat of emersion thermosetting resin on the tackiness agent continuously; The external protection that close adhesion is formed by thermoplastic on glass fiber reinforced layer.
