Abstract
The invention discloses an asphalt anticorrosive coating and a preparation method thereof. The asphalt anticorrosive coating comprises the following components in percent by weight: 40-50% of asphalt, 31-42% of a component A-a resin solutizer and epoxy resin mixture, 15-25% of a component B-a curing agent and 1.5-2% of a component C-filler aggregate. The preparation method comprises the following steps: uniformly mixing a toughening agent, a diluting agent and an anti-rust pigment to serve as the resin solutizer, shearing the solutizer and epoxy resin to obtain the component A, heating matrix asphalt to 140 DEG C, adding the component A, shearing, uniformly mixing, keeping the temperature for 1 hour, adding the component B-the curing agent and the component C-the filler aggregate, mechanically and uniformly mixing, and keeping the temperature of 140 DEG C for 2 hours to obtain the asphalt anticorrosive coating. The asphalt anticorrosive coating has the advantages of large adhesion force, high softening point, short drying time, excellent salt resistance and acid-base resistance properties, high hardness and the like; the preparation method is simple; special equipment is not required; and the construction cost is reduced.
Description
Technical field:
The present invention relates to the protective system technical field, specifically relate to a kind of bitumastic.
Background technology:
Pitch is the molecular mixture of multiple high score by complex chemical composition, has unique rheological, good agglutinating value(of coal), resistance to deterioration and water-tight corrosion-proof ability.Bitumastic is widely used in fields such as anti-corrosion of metal, waterproof and sealing materials.In early 1960s, bituminous epoxy appears at the U.S. first, and the people such as Thomas F Mika have reported this class high performance material for the first time with the form of patent.But until the nineties, people put forth effort to research and develop recoat material and roof surfacing material always.Early stage bitumastic is take the coal-tar pitch epoxypaint as main, but because of this paint adhesion power poor, anti-permeability is poor, complicated construction technique, higher to workmen's competency profiling, therefore do not have spread, the later stage people asphalt anti-corrosion coating that begins one's study, but because of set time long, film inhomogeneous and use as basic unit coating.
Summary of the invention:
The object of the present invention is to provide a kind of bitumastic and preparation method thereof, this protective system cohesive force is strong, curing speed is fast, coating is fine and close, corrosion-resistant and film forming is solid, and preparation method's technique is simple, and is easy to operate.
Purpose of the present invention is achieved through the following technical solutions:
A kind of bitumastic, formed by pitch, A component resin solubilizing agent and epoxy resin composition, B component solidifying agent and C component filler aggregate, the weight percent of each component is: pitch 40-50 ﹪, A component resin solubilizing agent and epoxy resin composition 31-42 ﹪, B component solidifying agent 15-25 ﹪ and C component filler aggregate 1.5-2 ﹪.
Preferred as technique scheme, described pitch is attached most importance to and is handed over 90 ﹟ matrix pitches.
Preferred as technique scheme, described resin solubilizing agent group is by toughner, and thinner and rust-stabilising pigment stir and form.
Preferred as technique scheme, described toughner is polypropylene glycol diglycidyl ether.
Preferred as technique scheme, described thinner is dibutyl phthalate.
Preferred as technique scheme, described Resins, epoxy is E-51 Resins, epoxy.
Preferred as technique scheme, described B component solidifying agent is modified amine, i.e. the affixture of diethylenetriamine and acrylate.
Preferred as technique scheme, described C component filler aggregate is phenolic resin microspheres.
A kind of preparation method of bitumastic is characterized in that may further comprise the steps:
(1) with toughner, thinner and rust-stabilising pigment stir as resin solubilizing agent, and solubilizing agent and Resins, epoxy are sheared and obtained the A component;
(2) matrix pitch is warming up to 140 ℃, adding A component shear agitation is even, constant temperature 1 h;
(3) then add B component solidifying agent and C component filler aggregate mechanical stirring is even, temperature remains on 140 ℃, and constant temperature 2h namely obtains the bituminous epoxy protective system.
Beneficial effect of the present invention is: gained coating has strong adhesion, softening temperature is high, time of drying is short, salt tolerance and resistance to acids and bases is good and hardness is large, and the preparation method is simple, need not specific installation, has shortened the duration, has reduced executive cost.
Description of drawings:
The present invention is described further below in conjunction with accompanying drawing:
Fig. 1 is production technological process of the present invention.
Embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment, and this embodiment only is used for explaining the present invention, does not consist of the restriction to protection domain of the present invention.
At first prepare resin solubilizing agent, the toughner polypropylene glycol diglycidyl ether that is about to measure, thinner dibutyl phthalate and rust-stabilising pigment add in the reactor successively, and high speed shear 10 minutes stirs stand for standby use.After E-51 Resins, epoxy measured, slowly add solubilizing agent, high speed shear evenly obtains the A component; Matrix pitch is warming up to 140 ℃, slowly adds A component shear agitation even, constant temperature 1h, then add B component modification amine curing agent and C component phenolic resin microspheres mechanical stirring is even, temperature remains on 140 ℃, and constant temperature 2h namely obtains the bituminous epoxy protective system.Its preparation technology's flow process as shown in Figure 1.The reagent that component concentration is different is tested respectively, and the requirement that prepared coal tar-epoxy coating all satisfies is as shown in table 1.
Table 1
By verification experimental verification, this bitumastic excellent property has satisfied every technical requirements of protective system.
