Description
Technical field
The utility model relates to the corrosion-resistanting interpolating port material of a kind of buried steel gas pipeline, oil and gas pipeline and heating network, relates in particular to a kind of construction install convenience, good sealing effect, the long shrink belt that includes viscoelastic body glue and pressure sensitive adhesive of anticorrosion life-span.
Background technology
Buried steel pipeline adopts radiation-crosslinking thermal-contraction belt as Crater antiseptic opening-supplementing material more, has developed again in recent years viscoelastic body rubber belt and has added pressure-sensitive adhesive type shrink belt corrosion-resistanting interpolating port technology.No matter whether traditional heat shrinkage belt material adopt priming paint, all has that installation requirement is high, difficulty of construction is large, preservative effect is subject to that construction infection is large, be difficult to the problems such as application under low temperature, and some opening-supplementing material just occurs anticorrosion inefficacy for 1 year afterwards installing to apply.And although viscoelastic body rubber belt has the anticorrosion and easy act energy of excellent sealing, exist physical strength low, easily the shortcoming such as peel off, cannot apply separately, many and pressure sensitive shrink belt supports the use.For this reason, we have invented a kind of construction install convenience, good sealing effect, the long shrink belt that includes viscoelastic body glue and pressure sensitive adhesive of anticorrosion life-span.
Utility model content
The utility model object is that a kind of construction install convenience, the long shrink belt that includes viscoelastic body glue and pressure sensitive adhesive of effective, anticorrosion life-span of sealing corrosion are provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of shrink belt that includes viscoelastic body glue and pressure sensitive adhesive, comprises backing layer; Parallel pressure-sensitive adhesive layer, the viscoelastic body glue-line of being coated with in surface of described backing layer; Described pressure-sensitive adhesive layer, the setting of viscoelastic body glue-line at grade, are respectively ribbon and arrange, and intermediate strap is viscoelastic body glue-line, and both sides band is pressure-sensitive adhesive layer; Described backing layer is to be made by the cross-linking radiation polyolefine with thermal contraction performance.
Preferably, the outside surface of described pressure-sensitive adhesive layer, viscoelastic body glue-line is provided with antiseized rete.
Preferably, described antiseized rete is made by being coated with the separate paper of anti-stick coating or antiadhesion barrier or polyester film.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
1. compare with general shrink belt, realized effective combination of several functions, each functional materials is worked in coordination, and has promoted the over-all properties of material;
2. compare with general shrink belt, the construction of pressure-sensitive adhesive layer of the present utility model is simple and convenient, constructor is required low, bonding firm; The construction requirement of viscoelastic body glue-line is low, and favorable anti-corrosion effect can also reduce derusting grade;
3. because backing layer is to be made by the cross-linking radiation polyolefine with thermal contraction performance, so its physical strength is much larger than common viscoelastic body rubber belt, can directly apply to pipeline corrosion protection repaired mouth and the mechanical protection meeting the demands can be provided, without using with other material-mix again;
4. be arranged on the pressure-sensitive adhesive layer on both sides, the preservative coat bonding strength at itself and weld bond two ends is high, and preserving and sealing is good, can resist the erosion of soil stress, for repaired mouth system provides safeguard protection.
5. the viscoelastic body glue-line in the middle of being arranged on, has excellent sealing corrosion performance.
6. the utility model also has puncture repairing effect, has guaranteed the long-term effectiveness of Crater antiseptic repaired mouth system.
