Abstract
The utility model discloses a polythene anticorrosive adhesive tape belonging to pipeline anticorrosion technology. In the prior art, the anticorrosion of the pipeline utilizing epoxy asphalt has bad uniformity and tightness, the polythene anticorrosive adhesive tape disclosed by the utility model takes a polythene film as a base material, and a self-adhered anticorrosive adhesive layer is adhered at one side of the base material. The polythene anticorrosive adhesive tape disclosed by the utility model has the advantages of high adhesiveness of the pipeline, strong environmental adaptability, large peeling strength and convenience in construction without pollution and completely meets the requirements of an anticorrosion engineering. The polythene anticorrosive adhesive tape can be widely applied to external anticorrosion and restoration work of water supply and drainage, oil-gas, coal gas conveyance steel pipelines and steel underground storage tanks in petroleum, natural gas, chemical industry and urban construction.
Description
Technical field
The utility model belongs to corrosion-proof technology for pipeline, specifically is a kind of polyethylene anticorrosion adhesive band.
Background technology
As everyone knows; China at present to the demands for energy amount along with expanding economy increases fast; The long in a large number distance of the transport pipe of Sweet natural gas, oil is laid; Envrionment conditions is complicated and changeable on the way, and is quite high to the requirement and the requirement of shelter of pipeline, and this has just proposed very high standard for our antiseptic project of conventional transport pipe.Bituminous epoxy is adopted in present domestic pipeline corrosion protection more, and bituminous construction and protection all are difficult to reach the requirement of construction quality, and homogeneity, stopping property are poor.
Summary of the invention
The technical problem that the utility model will solve and the technical assignment of proposition are to overcome the homogeneity that prior art exists pipeline corrosion protection with bituminous epoxy, the defective of stopping property difference, and a kind of polyethylene anticorrosion adhesive band is provided.
For achieving the above object, the polyethylene anticorrosion adhesive band of the utility model is to be base material with the Vilaterm diaphragm, adheres to self-adhesion anticorrosive adhesive adhesive layer in a side of said base material.
As the optimization technique measure: adhere to antiseized barrier film on the described self-adhesion anticorrosive adhesive adhesive layer.This tape roll is processed volume.The thickness of said base material is 200-800 μ m.The thickness of said self-adhesion anticorrosive adhesive adhesive layer is 200-800 μ m.The thickness of said antiseized barrier film is 40-90 μ m.
The utility model: the binding property of polyethylene anticorrosion adhesive band and pipeline is high, and adaptive capacity to environment is strong, and stripping strength is big, satisfies the demand of antiseptic project fully; Easy construction, pollution-free.Can be widely used in plumbing and the oil gas in oil, Sweet natural gas, chemical industry, the urban construction, the outer anticorrosion and recovery project that coal gas is carried steel pipe and the buried storage tank body of steel.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Label declaration among the figure: 1-base material, 2-self-adhesion anticorrosive adhesive adhesive layer, the antiseized barrier film of 3-.
Embodiment
Below in conjunction with Figure of description the utility model is further specified.
The polyethylene anticorrosion adhesive band of the utility model, as shown in Figure 1, it is to be base material 1 with the Vilaterm diaphragm, adheres to self-adhesion anticorrosive adhesive adhesive layer 2 in a side of base material 1.Concrete, adhere to antiseized barrier film 3 on the self-adhesion anticorrosive adhesive adhesive layer 2.This tape roll is processed volume; The thickness of base material is 200-800 μ m; The thickness of self-adhesion anticorrosive adhesive adhesive layer is 200-800 μ m; The thickness of antiseized barrier film is 40-90 μ m.Especially base material is that material, glue-line are that material is good with high viscosity thermoplastic modification butyl self-adhesion anticorrosive adhesive adhesive layer with high and low density synthesizing polyethylene diaphragm.
The method of manufacture of the utility model below is described:
(1) production of base material
The effect of base material provides the basis of carrying glue-line, bonding glue-line, requires himself to have certain mechanical strength again simultaneously.At present; The stripping strength of the similar universality product of domestic production is merely less than 20N/cm; Usually because bonding the appearance inadequately peels off, stopping property and preservative property have been had a strong impact on, in use in order to make product innovation once the good use properties that appears on the market; Must at first solve peel strength problem, be the index that this research emphasis is considered to back of the body stripping strength.Therefore, need include the interaction between base material and glue-line in the core limit of consideration on the base material formulating of recipe.Simultaneously, also must control the cost of product.All problems, all the mode through formula adjustment has obtained solution.

(2) production of glue-line
Table 2 glue-line prescription
Annotate: 10214 yuan/t of 1# cost; 9156 yuan/t of 2# cost.
According to above-mentioned prescription; Mix and get final product.
(3) multiple adhesive process
Adhesive tape is to form through the compound of glue-line and base material.Implement multiple glue with the rubber tri-roll press machine, technology is following:
Pillow four district's temperature: 140 ℃;
Pillow three district's temperature: 140 ℃;
Pillow two district's temperature: 140 ℃;
Pillow one district's temperature: 145 ℃;
Machine barrel four district's temperature: 130 ℃;
Machine barrel three district's temperature: 130 ℃;
Machine barrel two district's temperature: 130 ℃;
Machine barrel one district's temperature: 126 ℃.
The adhesive tape that above-mentioned multiple glue is processed rolls rolling through cooling, online side cut, slitter edge winding, center.
During use antiseized barrier film is peeled off, self-adhesion anticorrosive adhesive adhesive layer is bonded on the pipeline gets final product.
