Abstract
The invention discloses a high-pressure resistant glass fiber reinforced plastic enhanced steel-plastic composite pipe which belongs to the field of building. The high-pressure resistant glass fiber reinforced plastic enhanced steel-plastic composite pipe is prepared by adopting the following steps of: roughening a plastic layer on the outermost layer of a low-medium-pressure resistant steel-plastic composite pipe which is used as a framework, and then washing by using alcohol or ketone; brushing a coupling agent type binding agent to form a binding agent layer; twisting by using glass fiber immersed resin to form a glass fiber enhanced layer; and finally, closely adhering thermoplastic plastic to the glass fiber enhanced layer so as to form an outer protective layer. The high-pressure resistant glass fiber reinforced plastic enhanced steel-plastic composite pipe can fulfill the aims of preventing corrosion and greatly improving the pressure resisting capacity, and is compatible with excellent corrosion resistance and impermeability of a plastic pipe and high-pressure resistance of a steel pipe.
Description
Technical field
High pressure resistant glass fibre reinforced plastics enhancing steel of the present invention 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, are prone to 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 objective of the invention 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 mould pipe.
The objective of the invention is to realize like this: the steel-plastic composite pipe to press in anti-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; Soak into thermosetting resin with glass fibre then and twine, 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 present invention 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 invention is provided by following accompanying drawing 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 PUR, form inner binder layer 7, form inner protective layer 8 by thermoplastic with inner binder layer 7 close adhesion; Also apply the MD PUR on steel pipe 6 outer walls, form outer adhesive layer 5, form outer adhesive layer,, so, can produce the steel-plastic composite pipe of anti-mesolow by forming plastic layer 4 with the outer thermoplastic that bonds basic unit's 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 once 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; It is characterized in that: apply on the steel pipe inwall by the MD PUR; Adhesive layer in forming is by forming inner protective layer with the interior thermoplastic that bonds basic unit's close adhesion; Also apply the MD PUR on the outer wall of steel pipe, form outer adhesive layer, by forming plastic layer with the outer thermoplastic that bonds basic unit's 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; On glass fiber reinforced layer, closely be bonded with the external protection that thermoplastic forms.
