The alkali resistance protective system, the weight part of its constitutive material is: epoxy resin E-44 46, petroleum resin 32, sodium laurylsulfonate 2.2, tributyl citrate 14, kaolin 35, alcohol ester 12, vinyl three ('beta '-methoxy oxyethyl group) silane 8.5, triethylene tetramine 20, epoxy tetrahydro-2-ethylhexyl phthalate 2.6, polydimethylsiloxane 4.5, two ten four carbon alcohols esters 2.0, antioxidant NBC 3.1, methylene dichloride 42.
The preparation method of alkali resistance protective system may further comprise the steps:
(1) modification of epoxy resin E-44 is handled: the weight part by constitutive material takes by weighing epoxy resin E-44, and then with epoxy resin E-44, trolamine, nanometer deposed brick slag powder and nano titanium oxide by weight ratio 90: 33-35: 1.8-2.5:20-24 mixes;
(2) compound A: the methylene chloride of step (1) and 2/5-2/3 is mixed, the weight part of pressing constitutive material then adds petroleum resin, sodium laurylsulfonate, tributyl citrate, kaolin, alcohol ester 12, vinyl three ('beta '-methoxy oxyethyl group) silane, epoxy tetrahydro-2-ethylhexyl phthalate, polydimethylsiloxane, two ten four carbon alcohols ester and antioxidant NBCs, mixes and obtains compound;
(3) compound B: the weight part of pressing constitutive material mixes triethylene tetramine and remaining methylene chloride, and fully dissolving gets final product;
(4) the compound A of step (2) and the compound B of step (3) are got final product protective system by weight 1:1.3-1.5 mixing stirring 2.0-3.0h.
Beneficial effect of the present invention:
The present invention has adopted epoxy resin E-44 and petroleum resin as the major ingredient of protective system, methylene dichloride is as solvent, after applying coating solidifies, form polymeric material, become nonpoisonous and tasteless environment-friendly coating, steel surface there is fabulous sticking power, has added kaolin, alcohol ester 12, vinyl three ('beta '-methoxy oxyethyl group) silane and triethylene tetramine simultaneously, the corrosion resistance nature of whole coating system is obviously improved.
