Abstract
A strengthening type cold-entwining adhesive tape pertains to the petrochemical transportation pipeline technique field, which is characterized in that the utility model mainly comprises a PE film layer (1), a composite adhesive layer (2), a strengthening layer (3) and an adhesive layer (4); the PE film layer (1) and the adhesive layer (4) are arranged on the most outside layer; the composite adhesive layer (2) is tightly near the PE film layer (1); the strengthening layer (3) is positioned between the composite layer (2) and the adhesive layer (4). The utility model solves the problem of easy damage of an existing adhesive tape, has good puncture prevention capacity and simple structure, and is easy to be processed.
Description
Technical field
The utility model relates to the anticorrosion band of a kind of underground pipeline, the puncture-proof cold adhesive tape that twines of the good energy of especially a kind of intensity, specifically a kind of reinforced cold adhesive tape that twines.
Background technology
As everyone knows, utilizing ground-burying type pipe to carry out that crude oil, processed oil, intermediate, Sweet natural gas etc. carry in industries such as oil, chemical industry is a kind of most economical, mode of movement easily.Because existing ground-burying type pipe mostly is iron pipe greatly, it is embedded in the maximum problem in underground back is anticorrosion and antitheft problem, wherein anticorrosion is again the key that guarantees the normal operation of pipeline, traditional anti-corrosion method is to adopt at pipe surface spary antifouling paste, not only workload is big, need the repeated multiple times spary just can reach ideal preservative coat thickness, even after finishing behind the spary, also must regularly pipeline be dug out and safeguard after pipe surface cleaned out, expend lot of manpower and material resources every year and also be difficult to reach the ideal effect.People have invented and have utilized adhesive tape to carry out preserving method for this reason, the adhesive tape of waterproof solves the anticorrosion problem of buried pipe by having viscosity in the pipe surface winding, it is fast that it has speed of application, changes advantage easily, and this technology is being widelyd popularize at present.
But because existing adhesive tape has only the PE rete on surface and adhesive layer to form,, only probably it is pierced through, influences its water-repellancy if in construction, run in sharp object or the earth backfilling process metal or stone is pressed onto adhesive tape,
Summary of the invention
The purpose of this utility model is the problem that influences antiseptic property at existing anticorrosion adhesive tape cracky, and a kind of reinforced cold adhesive tape that twines that can prevent that hard thing from piercing through is provided.
The technical solution of the utility model is:
A kind of reinforced cold adhesive tape that twines, it is characterized in that it mainly is made up of PE rete 1, composite layer 2, enhancement Layer 3 and adhesive layer 4, wherein PE rete 1 and adhesive layer 4 are positioned at outermost layer, composite layer 2 next-door neighbour PE retes 1, and enhancement Layer 3 is between composite layer 2 and adhesive layer 4.
Described enhancement Layer 3 is PE compound glass screen grid, PE compound glass silk cloth, carbon fibril grid or carbon fibril cloth.Also can be grid or the cloth that similarly has certain intensity.
Also be provided with separation rete 5 in described adhesive layer 4 outsides.
The beneficial effects of the utility model:
The utility model has solved the existing cold strength problem that twines adhesive tape preferably, it is further perfect to make buried pipe anticorrosion obtain, can overcome in the past and introduce infiltration acceleration breakage corrosive problem owing to landfill materials such as running into stone, metal pierces through adhesive tape, and it is simple in structure, manufacturing process is simple, and the cost that is increased can and increase the service life from the replacing that reduces pipeline, reduce the unnecessary loss and be compensated.
Description of drawings
Fig. 1 is the cold section structure synoptic diagram that twines adhesive tape of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of reinforced cold adhesive tape that twines, it is mainly by PE rete 1, composite layer 2, enhancement Layer 3, adhesive layer 4 with separate rete 5 and form, its section structure as shown in Figure 1, wherein PE rete 1 with separate rete 5 and be positioned at outermost layer, composite layer 2 next-door neighbour PE retes 1, adhesive layer 4 next-door neighbours separate rete 5, and enhancement Layer 3 is between composite layer 2 and adhesive layer 4.Described enhancement Layer 3 can adopt PE compound glass screen grid, PE compound glass silk cloth, carbon fibril grid or carbon fibril cloth, also can be grid or the cloth that similarly has certain intensity.
If used adhesive layer 4 does not have autohension during concrete enforcement, can not bond mutually during the adhesive tape web-like that the process finishing coiled is convenient to transport from production line and can't unfolded words, separating 5 of retes can save, and this mainly decides on used adhesive material.
The production technique of adhesive tape of the present utility model and equipment all can adopt existing equipment to be realized, difference is the processes of bonding grid cloth together that increase more, and this and traditional adhesion process are identical.It is same as the prior art that other does not relate to part (as composite layer, PE rete, adhesive layer and separate the rete material therefor).
Claims (3)
1. reinforced cold adhesive tape that twines, it is characterized in that it mainly is made up of PE rete (1), composite layer (2), enhancement Layer (3) and adhesive layer (4), wherein PE rete (1) and adhesive layer (4) are positioned at outermost layer, composite layer (2) next-door neighbour PE rete (1), enhancement Layer (3) is positioned between composite layer (2) and the adhesive layer (4).
2. the reinforced cold adhesive tape that twines according to claim 1 is characterized in that described enhancement Layer (3) is PE compound glass screen grid, PE compound glass silk cloth, carbon fibril grid or carbon fibril cloth.
3. the reinforced cold adhesive tape that twines according to claim 1 is characterized in that also being provided with separation rete (5) in described adhesive layer (4) outside.
