Abstract
The invention discloses a kind of bitumastic and preparation method thereof, wherein, bitumastic is made up of pitch, resin solubilizing agent and epoxy resin composition, solidifying agent and filler aggregate, the weight percent of each component is: pitch 40-50 ﹪, component A resin solubilizing agent and epoxy resin composition 31-42 ﹪, B component solidifying agent 15-25 ﹪ and component C filler aggregate 1.5-2 ﹪.Preparation method is: by toughner, thinner and rust-stabilising pigment stir as resin solubilizing agent, solubilizing agent and epoxy resin are sheared and are obtained component A, matrix pitch is warming up to 140 DEG C, adds component A shear agitation evenly, constant temperature 1h, then B component solidifying agent is added and component C filler aggregate mechanical stirring is even, temperature remains on 140 DEG C, and constant temperature 2h, namely obtains bitumastic.Bitumastic of the present invention has strong adhesion, softening temperature is high, time of drying is short, salt tolerance and the advantage such as resistance to acids and bases is good and hardness is large, and preparation method is simple, without the need to specific installation, reduces executive cost.<!--1-->
Description
Technical field:
The present invention relates to protective system technical field, specifically relate to a kind of bitumastic.
Background technology:
Pitch is by the molecular mixture of multiple high score of 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, the people such as bituminous epoxy appears at the U.S. first, ThomasFMika report this kind of high performance material with the form of patent first time.But until the nineties, people put forth effort research and development recoat material and roof surfacing material always.Early stage bitumastic is based on coal-tar pitch epoxypaint, but because this paint adhesion is poor, anti-permeability is poor, complicated construction technique, higher to workmen's competency profiling, therefore do not have spread, later stage people begin one's study asphalt anti-corrosion coating, but because set time is long, uneven of film uses as base layer dope.
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, easy to operate.
Object of the present invention is achieved through the following technical solutions:
A kind of bitumastic, be made up of pitch, component A resin solubilizing agent and epoxy resin composition, B component solidifying agent and component C filler aggregate, the weight percent of each component is: pitch 40-50 ﹪, component A resin solubilizing agent and epoxy resin composition 31-42 ﹪, B component solidifying agent 15-25 ﹪ and component C filler aggregate 1.5-2 ﹪, described component C filler aggregate is phenolic resin microspheres.
Preferred as technique scheme, described pitch is attached most importance to friendship 90 ﹟ matrix pitch.
Preferred as technique scheme, described resin solubilizing agent 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 epoxy resin is E-51 epoxy resin.
Preferred as technique scheme, described B component solidifying agent is modified amine, i.e. the affixture of diethylenetriamine and acrylate.
A preparation method for bitumastic, is characterized in that comprising the following steps:
(1) by toughner, thinner and rust-stabilising pigment stir as resin solubilizing agent, and solubilizing agent and epoxy resin are sheared and obtained component A;
(2) matrix pitch is warming up to 140 DEG C, adds component A shear agitation evenly, constant temperature 1h;
(3) then add B component solidifying agent and component C filler aggregate mechanical stirring even, temperature remains on 140 DEG C, constant temperature 2h, namely obtains 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 preparation method is simple, without the need to specific installation, shortens the duration, reduces executive cost.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is production technological process of the present invention.
Embodiment:
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
First prepare resin solubilizing agent, be about to the toughner polypropylene glycol diglycidyl ether measured, thinner dibutyl phthalate and rust-stabilising pigment add in reactor successively, and high speed shear 10 minutes, stirs, stand for standby use.After being measured by E-51 epoxy resin, slowly add solubilizing agent, high speed shear evenly obtains component A; Matrix pitch is warming up to 140 DEG C, slowly adds component A shear agitation evenly, constant temperature 1h, then B component modified amine curing agent is added and component C phenolic resin microspheres mechanical stirring is even, temperature remains on 140 DEG C, constant temperature 2h, namely obtains bituminous epoxy protective system.Its preparation technology's flow process as shown in Figure 1.Respectively reagent different for component concentration is tested, the requirement that obtained coal tar-epoxy coating all meets, as shown in table 1.
Table 1
By verification experimental verification, this bitumastic excellent property, meets every technical requirements of protective system.
