Description
Technical field
The invention belongs to water-based and be coated with technical field, be specifically related to a kind of preparation method of soluble asphalt epoxy coating.
Background technology
Petroleum pitch has good cohesiveness, resistance to deterioration and water-tight corrosion-proof ability, be widely used as a long time build the road, anticorrosion and sealing material.The excellent point such as have raw material to be easy to get for water-tight corrosion-proof engineering, cheap is one of material be most widely used in domestic and international water-tight corrosion-proof engineering.Take bitumastic type epoxy as the protective system of base-material, maintain the water repelling property that bituminous composition is excellent, film flexibility and corrosion resistance nature.Overcome bituminous composition hardness not high, the shortcoming that tear resistance, cohesive force are poor and softening temperature is low, low price compared with epoxypaint.This external coating (EC) also has good anti-permeability performance, can meet the use of modern industry under harsh environmental conditions.
Asphaltic base epoxy coating is a kind of protective system occurred the sixties in last century, pittsburgh,U.S.A chemical company first patented (US52765288).With the increase of epoxy resin output, this coating obtains in states such as the U.S., Japan, France and develops rapidly, account for the half of epoxypaint, be used for the profit cabin, buried pipeline, basin etc. of the metal structures under harbour, harbour, production vessel, mine, oil tanker.
The seventies China carry out Epoxy coal tar pitch paint research, be successively developed into high-solid epoxy resin coal tar pitch as China Research Inst. of Petroleum and Natural-Gas Piping Science and dry coating, thick paste type epoxy coal tar coating and temperature curing epoxy low coal tar coating, other unit has also successively carried out the research of this type of coating, in urban construction, municipal administration, oil and gas pipes etc., obtain widespread use.
Epoxy resin refers to the class superpolymer containing more than 2 or 2 epoxy group(ing) in molecule.Ehter bond (-O-) contained in epoxy molecule structure and hydroxyl (-OH-) (ehter bond generated after also comprising epoxy resin and amine curing agent and through base) are all strong polar groups, these groups can make epoxy molecule and substrate surface, particularly and produce very strong cohesive force between metallic surface.And due to the Structure and form feature of epoxy resin self, make its outstanding sticking power hardly by the impact of cure shrinkage.After epoxy resin cure film forming, owing to containing stable phenyl ring and ehter bond in molecule, molecular structure has comparatively tight, and therefore better to the stability of chemical mediator, the media such as acid as isocyatic in centering, alkali and salt, can meet the needs of most of environment substantially.In addition, epoxypaint by changing epoxy resin, solidifying agent, the pigment be mixed into and the filler in formula, even can also have the kind of thinner etc. to form the different varieties of tens different properties, imparting the popularity of epoxypaint application.
