Abstract
The invention discloses a heat-shrinkable bus protection sleeve, and relates to the technical field of heat-shrinkable protection sleeves. The heat-shrinkable bus protection sleeve has a layer structure, wherein a first layer is a polyolefin substrate layer on which a hot melt glue layer is arranged. The polyolefin substrate layer is high-density polyolefin subjected to cross-linked radiation. The hot melt glue layer has sealing performance and flame retardance. The heat-shrinkable bus protection sleeve is waterproof, acid-proof, alkali-proof, anticorrosive, simple in structure and low in manufacture cost.
Description
Technical field
The present invention relates to the technical field of thermal shrinkage type protective casing.
Background technology
The now employed bus pipe row who buries ground or make somebody a mere figurehead need carry out preservative treatment; But the reason of expanding with heat and contract with cold owing to bus duct; Coefficient for require to adapt to its expansion as the shrink belt of opening-supplementing material requires no matter can both be fitted in fully on the outer wall of busbar under which type of environment.Present employed thermal shrinking type bus protective casing anti-corrosive properties are poor, and the adhesiveness between each layer is relatively poor, has reduced useful life.
Summary of the invention
The object of the invention provides a kind of thermal shrinking type bus protective casing with waterproof, acid-proof, alkali prevention, anticorrosion, simple in structure, low cost of manufacture.
A kind of thermal shrinking type bus protective casing, this thermal shrinking type bus protective casing is a layer structure, ground floor is a polyolefine base material layer, and hot melt adhesive layer is set on the polyolefine base material layer.
Polyolefine base material layer of the present invention is the high density polyolefins through crosslinking radiation.
Hot melt adhesive layer of the present invention has sealing.Hot melt adhesive layer of the present invention has anti-flammability.
Polyolefin mainly prepares with gas-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, being the lightest macromolecule, transparency is high, insulating properties, good corrosion resistance, air penetrability high (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 packaging material, fiber etc.
Under thermodynamic activity, thermal contraction casing tube radially evenly shrinks, hot melt adhesive layer fusing simultaneously; Evenly coat and be filled in bus pipe row surface, form continuously, protective system closely, can resist soil stress; Hydrostatic pressure resistant power, antikathode is peeled off, multiple corrosion behaviors such as resist chemical and mould.The present invention is applicable to-55 ℃～105 ℃, at low temperatures, does not crisply split; At high temperature, still can stable operation.Only need baking oven and spray gun in the installation process, just can be contracted on the bus easily.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:
As shown in Figure 1, the thermal shrinking type bus protective casing, this thermal shrinking type bus protective casing is a layer structure, ground floor is a polyolefine base material layer 1, and hot melt adhesive layer 2 is set on the polyolefine base material layer 1.
Polyolefine base material layer 1 of the present invention is the high density polyolefins through crosslinking radiation.
Hot melt adhesive layer 2 of the present invention has sealing.Hot melt adhesive layer 2 of the present invention has anti-flammability.
