Abstract
The invention provides a low temperature resistant winter epoxy coal tar pitch coating comprising a component A and a component B according to a weight ratio of 5-7:1. The component A is prepared from an epoxy resin, coal tar pitch, a dispersing agent, flatting agents, barium sulfate, a talcum powder, bentonite, and solvents in parts by weight; the component B comprises polyamide and xylene according to a weight ratio of 1:1. With combination of the epoxy resin and the coal tar pitch, not only excellent film-forming and corrosion resistance properties of the epoxy resin are exerted, but also the problems of high temperature flow and low temperature cold brittleness of a pitch material are better solved, the coating layer is resistant to low temperature and can be used in winter, and the service life of the coating is prolonged.
Description
Technical field
The present invention relates to the painting technical field, be specifically related to a kind of low temperature resistant winter to use the epoxy coal tar coating.
Background technology
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.
The epoxy coal tar coating is through the three-dimensional interpenetrating polymer network thermosetting material of a kind of cross-linking density of curing reaction formation " overall situation is low, local high ", makes it have excellent resistance to elevated temperatures.But at low temperatures, the epoxy coal tar coating is along with the reduction of temperature, and its intensity and stiffness obviously increase, but its deformability significantly descends, namely fragility increase, toughness drop, low temperature effect tensile strength and the deformability of this coating.In a single day crackle appears in coating, its self-healing that can not heat up, thus can under the Conditionings such as various load, water, mist, accelerate the failure, and form large-area destruction.
Summary of the invention
Purpose of the present invention will provide a kind of low temperature resistant winter to use the epoxy coal tar coating exactly, improves the resistance to low temperature of coating, thereby reaches the quality of raising product and the protection period of coating.
In order to achieve the above object, the invention provides a kind of low temperature resistant winter to use the epoxy coal tar coating, by component A and component B by weight forming for 5-7:1; Wherein component A is prepared from by weight by following component:
Described component B is comprised of by weight 1:1 polymeric amide and dimethylbenzene.
Further, described Resins, epoxy is the bisphenol A-type solid epoxy, and epoxy equivalent (weight) is 450-500.
Described solvent is dimethylbenzene, butanols and alcohol.
Described dispersion agent is a kind of in stearate, polyethylene wax, ethylene group bis-stearamides, glyceryl monostearate, the Tristearoylglycerol.
Described flow agent is silicone oil, polydimethylsiloxane, polyether polyester modified organic silicon oxygen alkane.
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 5-7:1 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.
Epoxy coal tar coating of the present invention is applied-40 ℃ of conditions, and the test specimen coating curing was placed on one 60 ℃ after 100 days, and the tensile strength of its test specimen and deformability significantly do not change, and illustrate that coating of the present invention has resistance to low temperature.
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.
