Abstract

The invention discloses a kind of anticorrosion belt, film layer (1), anticorrosion antiwear layer (2), articulamentum (3), adhesive layer (4) are followed successively by from top to bottom.The invention also discloses a kind of preparation method of above-mentioned anticorrosion belt, comprise the following steps：Anticorrosion antiwear layer (2) and articulamentum (3) are common with film layer (1) and adhesive layer (4) to form anticorrosion belt by roll-in by heating；Or anticorrosion antiwear layer (2) and articulamentum (3) form extexine anticorrosion belt, then be compounded to form anticorrosion belt with adhesive layer (4) with film layer (1) by heating by roll-in.Pipeline anticorrosion belt disclosed by the invention has the advantages that environmental protection, high intensity, good toughness, rub resistance, waterproof, protection against the tide, high-low temperature resistant, corrosion-resistant and long service life.

Description

A kind of anticorrosion belt and preparation method thereof
Technical field
The invention belongs to pipeline corrosion protection field of material technology, more particularly to a kind of anticorrosion belt and preparation method thereof.
Background technology
At present, especially in oil field ground oil-gas gathering and transferring pipeline field, the corrosion-proof pipe line of use is still tradition in pipeline corrosion protection field Asphalt pipe, glass reinforced plastic pipe, polyethylene tape anti-corrosion pipe etc., these products all expose some and ask in actual applications Topic, energy consumption is big, pollution environment, the problems such as heat-shrinkable is poor, interlayer caking property is poor, reduces service life.
Application No. 201220444716.7 discloses a kind of corrosion-resistant anticorrosion belt, base material PVC and glass fibre in this patent Cloth is to vulcanize to connect by fluorosioloxane rubber, and the intensity on top layer has certain limitation when being used under the conditions of high-strength and wear-resisting grade, influences The range of application of this anticorrosion belt.
The content of the invention
For the defect for overcoming above-mentioned prior art to exist, it is an object of the invention to provide a kind of anticorrosion belt and preparation method thereof, tool There are environmental protection, high intensity, rub resistance, waterproof, protection against the tide, high-low temperature resistant, corrosion-resistant, long service life and easy to use etc. Advantage.
To achieve the above object, the present invention uses following technical scheme：
A kind of anticorrosion belt, is followed successively by film layer, anticorrosion antiwear layer, articulamentum, adhesive layer from top to bottom.
The film layer is polyethylene terephthalate (PET) or polyethylene terephthalate-foil laminated film.
The anticorrosion antiwear layer is continuous fiber reinforced thermoplastic plastic composite.
The thermoplastic be selected from polyethylene, polypropylene, polyethylene terephthalate, polyamide 6, polyamide 66, At least one in polybutylene terephthalate (PBT) or polyvinyl chloride.
The continuous fiber is fine continuous glass fibre, continuous aramid fiber, superhigh molecular weight polyethylene fibers or continuous basalt At least one in dimension.
The articulamentum is at least one in polyester fiber cloth, polyamide fibre (PA) fiber cloth or acrylic fiber cloth.
The adhesive layer is ethylene-vinyl acetate PUR, polyamide hot, epoxy resin coal tar pitch epoxy glue or butyl At least one in rubber based adhesives.
The thickness of the film layer is 0.1~0.5mm.
The thickness of the anticorrosion antiwear layer is 0.15~1mm.
The thickness of the articulamentum is 0.2~0.4mm.
The thickness of the adhesive layer is 0.5~1.5mm.
A kind of preparation method of above-mentioned anticorrosion belt, comprises the following steps：
