Abstract
The invention provides an epoxy coal tar pitch paint comprising a component A and a component B according to a weight ratio of 1:1-2. The component A is prepared by mixing an epoxy resin, a dispersing agent, fillers and solvents; the component B is prepared by mixing polyamide, coal tar pitch, bentonite, the solvents, the dispersing agent and a grinding slurry. With combination of the epoxy resin and the coal tar pitch, the epoxy coal tar pitch paint not only exerts excellent film-forming and corrosion resistance properties of the epoxy resin, but also better solves the problems of high-temperature flow and low-temperature cold brittleness of a pitch material. The paint prepared by the epoxy resin and the coal tar pitch which has the advantages of low price and convenient construction is combined with both advantages of the epoxy resin and the coal tar pitch, and thereby improving corrosion resistance and service life of the paint.
Description
Technical field
The present invention relates to the painting technical field, be specifically related to a kind of epoxy coal tar coating.
Background technology
Along with the pipeline that crosses the river, middle of the river water-fetching head and bank connecting well pipeline, sewage deep water discharge tube, long apart from the bottom of the river or the building of seafloor water delivery pipe line, the underwater pipeline protective system arises at the historic moment.This coating has good and stable antiseptic property, especially the corrosion of sea water resistance, river take thick film, long-acting and be applicable to harsh corrosion working conditions as principal character.
The epoxy coal tar coating is a class protective system that occurs the sixties in 20th century, it combines sticking power, physical strength and the solvent resistance of acid-and base-resisting, water tolerance and the Resins, epoxy of coal tar pitch, anticorrosive coating kind for good is widely used in the industries such as water conservancy, petrochemical complex, shipbuilding and transportation.Having excellent water-resistance of epoxy coal tar coating is immersed in the water 10 days, its water-intake rate only 0.1% ~ 0.2%; The erosion of the waterproof and more anti-chemical of paint film; Coating still has good wettability to the steel surface that does not fully eliminate rust; Cheap; Solids content is high, can obtain thick film.
Summary of the invention
Purpose of the present invention will provide a kind of epoxy coal tar coating exactly, and this coating has good antiseptic property, and its guard time is long, and the fields such as waterpipe and boats and ships that can be widely used in are used for corrosionproof protection.
In order to achieve the above object, the invention provides a kind of epoxy coal tar coating, formed for 1:1-2 by weight by component A and component B; Wherein component A is prepared from by weight by following component:
Described component B is prepared from by weight by following component:
Further, described Resins, epoxy is the bisphenol A-type solid epoxy, and epoxy equivalent (weight) is 450-500.
Further, described polymeric amide is 650 Versamids.
Further, described solvent is dimethylbenzene and butanols.
Further, described filler is process white, wilkinite and talcum powder, and described process white, wilkinite and talcous weight ratio are 20:1:29-39.
Further, described ground slurry is water-ground limestone.
The preparation method of epoxy coal tar coating of the present invention mixes in reactor by prescription adding each component first to prepare component A, prepares component B again; And then be that the ratio of 1:1-2 mixes, leaves standstill filtration and namely gets the epoxy coal tar coating in the weight ratio of component A and component B.
The present invention combines Resins, epoxy with coal tar pitch, both brought into play film forming properties and the Corrosion Protection of Resins, epoxy excellence, has solved preferably again the difficult problems such as the trickling of bituminous material high temperature, brittle fracture under low temperature.The coating that adopts Resins, epoxy and coal tar pitch cheap, easy construction to be mixed with combines the advantage of the two, has improved the Corrosion Protection of coating.
Behind the test specimen coating curing with epoxy coal tar coating coating of the present invention, through test, after 20 days, take out test specimen in the immersion entry, weight does not increase, and size does not rise, and proves that the coating moisture impermeability is good.Be used in the seawater, marine organisms can't take root existence in coating, thereby have promoted the anticorrosion and antifouling property of boats and ships.
Coating of the present invention can spray as usual at-20 ℃, and is also capable of coating with rust, do not expand through checking 180 ℃ of coat-thicknesses, do not melt, and in the time of subzero one 60 ℃, firmly not crisp, thickness does not shrink.
The coating protection time of the present invention is long, its use after 5 years corrosion protection coating non-foaming, wrinkle resistant, do not chap, do not peel off.Can extensively be adapted to the Pipeline Coating for Corrosion Preventions such as buried combustion gas, tap water, sewage, seawater, oil, petroleum storage tanks, gas chamber inside and outside wall are anticorrosion; The mechanical anti-corrosions such as drilling unit, anticorrosion and metallurgical, mechanical, building materials peculiar to vessel, printing and dyeing, papermaking, weaving, coal mining; And the aspects such as antirust paint film such as steel plate, steel pipe, angle steel all can reach not thoroughly wet corrosion protection coating.
