Abstract
The utility model relates to a kind of viscoelastic body shrink belt, comprises thermal contraction base material, elastomer layer; Described elastomer layer is arranged on the surface of thermal contraction base material; Viscoelastic body shrink belt described in the utility model has the following advantages: 1. the viscoelastic body adopting the polyisobutenyl with cold flow characteristic to make is adhesive layer, do not need to be coated with priming compared with hot melt glue type 3PE polyethylene thermal contraction strap, do not need preheating, do not need long-time fire roasting, construct simple and convenient; And maintenance-free; 2. there are good pliability and higher stripping performance when ultra low temperature-50 DEG C, hang down without dripping when high temperature 85 DEG C, within the scope of-50 DEG C-85 DEG C, application can be installed.
Description
Technical field
The utility model relates to a kind of pipeline corrosion protection shrink belt, particularly relates to a kind of viscoelastic body shrink belt.
Background technology
Mostly adopt hot melt glue type shrink belt as the corrosion-resistanting interpolating port material of steel pipe weld bond at present both at home and abroad, on the one hand, hot melt glue type shrink belt is higher to construction requirement, not easily installs, corrosion protection weak effect, some shrink belts are installed and are just occurred anticorrosion inefficacy afterwards in 1 year; On the other hand, its temperature limit is limited comparatively large, application difficult at low ambient temperatures, and material self is easily brittle failure also; We have developed a kind of favorable anti-corrosion effect, can use under ultra-low temperature surroundings and simple viscoelastic body shrink belt of constructing for this reason.
Utility model content
The utility model object provides a kind of favorable anti-corrosion effect to overcome the deficiencies in the prior art, can use under ultra-low temperature surroundings and simple viscoelastic body shrink belt of constructing.
For achieving the above object, the technical solution adopted in the utility model is: a kind of viscoelastic body shrink belt, comprises thermal contraction base material, viscoelastic body layer; Described viscoelastic body layer is arranged on the surface of thermal contraction base material.
Preferably, described viscoelastic body shrink belt, also comprises mould release membrance; Described mould release membrance is arranged on the outer surface of viscoelastic body layer.
Preferably, described thermal contraction base material is made up of cross-linked polyolefin.
Preferably, described viscoelastic body layer is made up of polyisobutenyl rubber.
Preferably, described mould release membrance is made up of release liners or PET film.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
1. adopt the viscoelastic body with cold flow characteristic to be adhesive layer, do not need to be coated with priming compared with hot melt glue type 3PE polyethylene thermal contraction strap, do not need preheating, do not need long-time fire roasting, construct simple and convenient; And maintenance-free;
2. there are good pliability and higher stripping performance when ultra low temperature-50 DEG C, hang down without dripping when high temperature 85 DEG C, within the scope of-50 DEG C-85 DEG C, application can be installed.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of viscoelastic body shrink belt described in the utility model;
Wherein: 1, thermal contraction base material; 2, viscoelastic body layer; 3, mould release membrance.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is a kind of viscoelastic body shrink belt described in the utility model, comprises thermal contraction base material 1, viscoelastic body layer 2, mould release membrance 3; Described viscoelastic body layer 2 is arranged on the surface of thermal contraction contracting base material 1; Described mould release membrance 3 is arranged on the outer surface of viscoelastic body layer 2; Described thermal contraction base material 1 is made up of cross-linked polyolefin; Described viscoelastic body layer is made up of polyisobutenyl rubber; Described mould release membrance 3 is made up of release liners or PET film.
During work, described thermal contraction base material 1 provides mechanical protection, and viscoelastic body layer provides corrosion protection, and mould release membrance 3 is for antiseized, instant packed.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
1. adopt the viscoelastic body with cold flow characteristic to be adhesive layer, do not need to be coated with priming compared with hot melt glue type 3PE polyethylene thermal contraction strap, do not need preheating, do not need long-time fire roasting, construct simple and convenient; And maintenance-free;
2. there are good pliability and higher stripping performance when ultra low temperature-50 DEG C, hang down without dripping when high temperature 85 DEG C, within the scope of-50 DEG C-85 DEG C, application can be installed.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
