Abstract
The utility model relates to a cold winding tape with epoxide coal pitch which is made of epoxide coal pitch coated on a substrate with a glue applicator. The sectional plane of the utility model is composed of epoxide coal pitch, the substrate and a piece of plastic cloth with the thickness of 1 mm to 2 mm, the width of 400 mm, 300 mm, 200 mm, etc., and the length of 50 m, and the substrate is a piece of glass cloth or non-woven fabric. The utility model can be used under normal temperature without environmental requirement, and can be widely used for the antisepsis of various pipelines in gas field, city and factory, and the anticorrosive life is more than 50 years.
Description
The utility model belongs to anticorrosion heavy chemicals
Present domestic several adhesive tapes that have, as polyethylene tape, hinge, electrical adhesive tape.In these products, polyethylene tape has preservative activity, other gummed paper adhesive tape is mainly used in bonding and insulation is used, though and polyethylene tape has preservative activity, but its physical strength is low, construction and use in be easy to damage, and execution conditions require harshly, weather condition are next can not construct as rainy day, dust storm sky, moist dew etc.; Recently, also have the hot tape wrap of a kind of petroleum pitch abroad, the main component of the glue on its tape wrap is a petroleum pitch, to use natural gas, liquefaction vapour heating tape wrap surface when using this tape wrap, after tape wrap surface petroleum pitch dissolves, twine being bonded on the member again, it is very inconvenient to construct.
In order to overcome the shortcoming and defect of present impregnating material, the utility model proposes a kind of novel anticorrosion tape wrap, it is epoxide coal bituminous Cold winding band, it is not only by new material composition (epoxide coal bituminous) and forms, and construction is not subjected to the constraint and the restriction of nature, weather condition when using, and is a kind of high mechanical strength that has, high electrical performance, high chemical stability, the impregnating material that low environment pollutes.
Accompanying drawing 1 is a cross-sectional view of the present utility model.
A kind of epoxy coal bitumen cold-tangled belt that epoxide coal bituminous glue is consisted of with the gluing machine coating, the cross-section structure that it is characterized in that this Cold winding band is epoxide coal bituminous glue, base material, Polypropylence Sheet consists of, its thickness is 1mm～2mm, and the width of tape wrap is 400mm, 300mm, 200mm etc., and length is 50 meters, 100 meters, base material is glass cloth or nonwoven.
Epoxide coal bituminous Cold winding band is not only by new material composition and is formed, have high mechanical strength, high electrical performance, high chemical stability, the low environment pollution characteristics, and construction is not subjected to the constraint and the restriction of various natural climate conditions when using, and can be widely used in the oil transportation of oil-gas field, gas transmission, water pipe, the bottom of pipe-line equipments such as town gas, tap water, chemical plant, kerosene factory, sewage work, heat power plant, mine, oil tank, gas holder; The waterproof, the antiseep that also can be used for buildings.The utility model can be used in-40 ℃～100 ℃ for a long time, and at soda acid salt solution, gasoline, kerosene, the medium-term and long-term no change that soaks of diesel oil, the anticorrosion life-span can reach more than 50 years.
Embodiment, earlier press this paper formula rate with combined composition Resins, epoxy 20%, pitch 40%, scallion oil 20%, mica powder 50%, talcum powder 15% and other are made epoxide coal bituminous glue under 50 ℃～80 ℃ of temperature, then non-woven fabrics is immersed in the epoxide coal bituminous glue, and the non-woven fabrics behind impregnation is by certain glue amount and the thickness of spreadometer control again.Make epoxide coal bituminous Cold winding band through spreadometer roll-in winding, for preventing the adhesion of glue and roller, a little talcum powder loose on roller, its cross-section structure is exactly shown in the accompanying drawing 1, constitute by epoxide coal bituminous glue (1) non-woven fabrics (2) plastic cloth (3), 50 meters of length, thickness is 1mm-2mm.
Use the method for epoxide coal bituminous Cold winding band to be: first must remove oil stain and glass substance, greasy dirt, the dust on the surface of preserver, exposes smooth solid surface; Second coats a kind of anticorrosion primer on the surface of handling well, be coated with evenly, must not holiday; After the 3rd surface has been coated with primer, twines immediately or paste epoxide coal bituminous Cold winding band, when twining adhesive tape, must keep the tacky state of primer, be coated with a primer after tape wrap twines again and get final product.
Claims (2)
1, a kind of epoxide coal bituminous Cold winding band that epoxide coal bituminous glue is constituted with the adhesive applicator coating, the section that it is characterized in that this tape wrap is to be made of epoxide coal bituminous glue (1), base material (2), plastic cloth (3), its thickness is 1mm-2mm, width is 400mm, 300mm, 200mm etc., length is 50 meters.
2, epoxide coal bituminous Cold winding band according to claim 1, the base material that it is characterized in that this Cold winding band is woven fiber glass or non-woven fabrics.
