Abstract
An anticorrosion heat-shrinkable sleeve for pipeline is composed of a sleeve body and a heat-shrinkable anticorrosion material. A heat-shrinkable sleeve for pipeline is a laminated structure, the first layer is a polyolefin substrate layer, and a hot-melt adhesive layer and a liquid epoxy coating layer are sequentially arranged on the polyolefin substrate layer. The polyolefin substrate layer is high-density polyethylene subjected to crosslinking radiation. The polyolefin substrate layer is coated on the polypropylene pipeline. The hot melt adhesive layer has sealing performance. The utility model aims at providing a pipeline anticorrosion heat shrink sleeve which has the advantages of water resistance, acid resistance, alkali resistance, corrosion resistance, simple structure and low manufacturing cost.
Description
Technical field
The utility model relates to and buries ground or built on stilts steel pipe weld bond corrosion-resistanting interpolating port and the technical field of the thermal shrinkage type anti-corrosion material that designs.
Background technique
Now employed weld bond place of burying ground or built on stilts steel pipe need carry out preservative treatment, but the reason of expanding with heat and contract with cold owing to steel pipe, no matter coefficient for require to adapt to its expansion as the heat-contraction sleeve of opening-supplementing material can both be fitted on the outer wall of steel pipe under which type of environment fully.The performance of present employed heat-contraction sleeve corrosion resistance aspect is single, and the adhesiveness between each layer is relatively poor, has reduced working life.
Summary of the invention
The utility model purpose provides a kind of pipeline corrosion protection heat-contraction sleeve with waterproof, acid-proof, alkali prevention, anticorrosion, simple in structure, low cost of manufacture.
The utility model adopts following technological scheme for achieving the above object:
A kind of pipeline corrosion protection heat-contraction sleeve, this heat-contraction sleeve are stratiform structure, and first layer is a polyolefine base material layer, set gradually heat-fusing glue layer, liquid epoxy coating on the polyolefine base material layer.Described polyolefine base material layer is the high density polyolefins through crosslinking radiation.Described polyolefine base material layer is coated on the polypropylene pipe.Described heat-fusing glue layer has sealing.
The utility model adopts technique scheme, compared with prior art has following advantage:
Polyolefin mainly prepares with vapor-phase polymerization.135 ℃ of melt temperatures, density 0.91 gram per centimeter
3, normal temperature is placed, and crystal transfer can take place.Availablely extrude, blowing becomes pipe, plate, film and fiber with processes such as injections.Because its anti-creep and stress crack resistance performance are outstanding ,-25～100 ℃ of pipeline materials that use down of normal work.Poly(4-methyl-1-pentene), the polymer of 4-methyl-1-pentene.Prepare with the stereospecfic polymerization method.About 240 ℃ of melt temperature, density 0.83 gram per centimeter
3, be the lightest macromolecule, the transparency height, insulating properties, good corrosion resistance, air penetrability height (being poly 10 times), but shock-resistant, stress cracking and photooxidative aging performance are relatively poor.Available injection and extrusion method processing.Be used to make optical instrument, chemistry and medical apparatus, electronic device and insulating material, gas separation membrane and wrapper, fiber etc.
Under thermodynamic activity, heat-contraction sleeve radially evenly shrinks, heat-fusing glue layer fusing simultaneously, evenly coat and be filled in pipe surface, form continuously with former pipeline anticorrosion coating, protective system closely, can resist soil stress, hydrostatic pressure resistant power, antikathode is peeled off, multiple corrosion behaviors such as resist chemical and mould.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:
As shown in Figure 1, heat-contraction sleeve of the present utility model is a stratiform structure, and first layer is a polyolefine base material layer 1, sets gradually heat-fusing glue layer 2, liquid epoxy coating 3 on the polyolefine base material layer 1.Described polyolefine base material layer 1 is the high density polyolefins through crosslinking radiation.Described polyolefine base material layer 1 is coated on the polypropylene pipe.Described heat-fusing glue layer 2 has sealing.
