Abstract
A heat-shrinkable bus sleeve relates to the technical field of heat-shrinkable protection sleeves. The heat-shrinkable bus sleeve adopts a layered structure; the first layer is a polyethylene substrate layer which is made of high-density polyethylene going through radiation crosslinking; and a hot melted glue layer with sealing and fire resisting properties is arranged on the polyethylene substrate layer. The utility model aims to provide the heat-shrinkable bus sleeve with the advantages of water, acid, alkali and corrosion preventing properties, simple structure and low manufacturing cost.
Description
Technical field
The utility model 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 utility model purpose provides a kind of thermal shrinking type bus sleeve with waterproof, acid-proof, alkali prevention, anticorrosion, simple in structure, low cost of manufacture.
A kind of thermal shrinking type bus sleeve, this thermal shrinking type bus sleeve are layer structure, and ground floor is a polyethylene base material layer, on the polyethylene base material layer hot melt adhesive layer is set.
Polyethylene base material layer of the present utility model is the high density polyethylene (HDPE) through crosslinking radiation.
Hot melt adhesive layer of the present utility model has sealing.Hot melt adhesive layer of the present utility model has anti-flammability.
Polyethylene has excellent chemical stability, various chemical substances such as salt tolerant acid, hydrofluoric acid, phosphoric acid, formic acid, amine, NaOH, potassium hydroxide under the room temperature, and nitric acid and sulfuric acid have stronger destruction to polyethylene.The easy photooxidation of polyethylene, thermal oxidation, ozone decompose, and degrade easily under action of ultraviolet radiation, and carbon black has excellent light shield effect to polyethylene.Reflections such as crosslinked, chain rupture, formation unsaturated group can take place after the raying.
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 utility model 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 utility model.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:
As shown in Figure 1, thermal shrinking type bus sleeve, this thermal shrinking type bus sleeve are layer structure, and ground floor is a polyethylene base material layer 1, on the polyethylene base material layer 1 hot melt adhesive layer 2 is set.
Polyethylene base material layer 1 of the present utility model is the high density polyethylene (HDPE) through crosslinking radiation.
Hot melt adhesive layer 2 of the present utility model has sealing.Hot melt adhesive layer 2 of the present utility model has anti-flammability.
