Abstract
A fast-drying non-solvent anticorrosion epoxy band is composed of anticorrosion band made of non-woven polypropylene fibre felt and paint layer. Said paint is prepared from the component A consisting of epoxy resin, coal asphalt, anthracene oil, plasticizer, levelling agent and defoaming agent and the component B consisting of fast solidifying agent, quartz powder, anti-depositing agent, toughening agent, levelling agent and defoaming agent through proportional mixing and stirring.
Description
Technical field
The present invention relates to a kind of anticorrosion band, relate to a kind of drip-dry epoxy presservative strip without solvent specifically.
Background technology
Current, anticorrosion for steel pipe and cast iron pipe in the underground pipeline corrosion-resistant field at home and abroad is that protective system or the paint with various types of properties sprays or brush the formation inside and outside anticorrosive coating to internal and external walls mostly.Because general paint antiseptic property is relatively poor, the antifouling paint that is used for underground pipeline is rarely found.And in the impregnating material commonly used now, as polyethylene tape, hinge, electrical adhesive tape etc., in these products, polyethylene tape has preservative activity, other gummed paper adhesive tape be mainly used in bonding and the insulation usefulness, though and polyethylene tape has preservative activity, but its physical strength is low, construction and use in be easy to damage, and execution conditions harshness, weather condition are next can not construct as rainy day, dust storm sky, moist dew etc.; And in the protective system commonly used now, macromolecule epoxy resin class protective system uses very general.Epoxy coating generally all is that macromolecule epoxy resin, toughner, flow agent, silica powder and solidifying agent mix by a certain percentage, though it is very extensive that this traditional epoxy coating is used, but also exist following shortcoming: curing speed is slow at normal temperatures, doing solid work needs more than 2 days, the completely solidified time is longer, cause construction period to prolong constructional difficulties.
Summary of the invention
The objective of the invention is to overcome the shortcoming and defect of present impregnating material, a kind of high mechanical strength is provided, the high electric insulation performance, high chemical stability, low environment pollutes, and be anticorrosion tape base material with the polypropylene fibre non-woven mat, and cohesive force is strong, cost is low, and antiseptic property is good and set time short, easy working drip-dry epoxy presservative strip without solvent.
Drip-dry epoxy presservative strip without solvent coating of the present invention is mainly formed the A component by Resins, epoxy, coal-tar pitch, carbolineum, softening agent, flow agent and suds suppressor; Form the B component by quick curing agent, silica powder, anti-settling agent, toughner, flow agent and defoamer; A, B component composition constitute (by mass percentage):
A component: the attached fat 10～50% of modified epoxy
Coal-tar pitch 10～40%
Carbolineum 10～40%
Softening agent 1～20%
Flow agent 1～5%
Suds suppressor 1～5%
B component: solidifying agent 5～30%
Silica powder 25～60%
Anti-settling agent 5～20%
Toughner 5～10%
Flow agent 1～5%
Promotor 1～5%
Defoamer 1～5%
A, B mixture ratio example are 1: 1 (mass ratio).
Wherein said quick curing agent component constitutes (by mass percentage):
Epoxy hardener 5,768 10～50%
Epoxy altax P-30 10～50%
Its optimum proportion is 5768: DMP-30=4: 1.
The base material of described anticorrosion band is a nonwoven polypropylene fabric, and dip-coating improves the epoxy altax P-30 and the silane coupling agent KH560 of coating performance on cloth.
Using method of the present invention is: the pipe surface cleaning that will handle earlier before pipeline is carried out rotproofing is clean, the A that will prepare in advance, B component are even with 1: 1 proportioning field mix again, can brush or spray with hairbrush or spray coating mechanical, structure by coating-anticorrosion band-coating is entangled in steel tube surface again, leaves standstill and forms the epoxy anticorrosion layer after the spontaneous curing.
Because anticorrosion tape base material of the present invention is selected nonwoven polypropylene fabric for use, this material is the good novel synthon of physical strength height, erosion resistance, and the content of wax, thickness are uneven on the surface, make preservative coat surfacing, bonding closely, few, the electrical property of pin hole and antiseptic property be good.In addition, dip-coating improves the epoxy altax P-30 and the silane coupling agent KH560 of coating performance on cloth, the cohesive force and the mechanical property of preservative coat have been increased, coating of the present invention not containing benezene solvent belongs to the environmental friendly, anti-corrosive material, and be ambient cure, normal temperature construction in use, also eliminated the environmental pollution in the construction.Coating of the present invention adopts quick curable epoxide 5768, and adds the epoxy altax P-30 of suitable proportion, and the preservative coat curing speed is fast, does solid work following need of normal temperature several hrs, can be in one day completely solidified; Solved a long difficult problem of construction time.
