Background technology
With economic continuous development, the demand of industrial floor coatings is also increasing.Traditional SOLVENT BASED EPOXY FLOOR COATINGS contains more organic solvent, and these solvents enter air in coating material production and construction stage, there is disaster hidden-trouble, to environment, human body is worked the mischief.Compared with traditional SOLVENT BASED EPOXY FLOOR COATINGS, aqueous epoxy floor coating has very big advantage:Using water as disperse medium, the volatile organic solvent of toluene, dimethylbenzene etc is not contained, do not result in environmental pollution, the hidden danger also do not caught fire;Construction, solidification in environment that can be moist again;There is good adhesive force to most of base materials, even the substrate surface of humidity equally also has good caking property:Paint film after solidification closes damp soft, and texture is preferable, with preferable antiseptic property and unidirectional vapour transmission.With the continuous improvement of people's environmental consciousness, Water-borne modification, solvent free, the large arch dam of floor coatings is into the inexorable trend of development.
The content of the invention
The present invention is a kind of new aqueous epoxy floor coating and its preparation technology, is a kind of industrial terrace coating process, the characteristics of with hardness height, good wearability, high adhesive force and excellent chemical resistance.
To solve above-mentioned technical problem, a kind of new aqueous epoxy floor coating involved in the present invention and its preparation technology, it is characterised in that be formulated by the mass fraction ratio of its raw material:First component:80 parts of aqueous epoxy resins, 20 parts of reactive diluent;Component B:Aqueous epoxy curing agent 20-25 parts, deionized water 25-35 parts, RS610 wetting dispersing agent 0.2-0.6 parts, DF681F defoamer 0.3-0.5 parts, scratch resistance auxiliary agent 0.5-1 parts, A401 alkali swollen thickener 0.2-0.4 parts, titanium dioxide 4-6 parts, BGS phthalocyanine blue 2-3 parts, 801 strontium chromate 1-1.5 parts, precipitated calcium carbonate 10-15 parts, blanc fixe 20-25 parts, super-fine talc 10-15 parts.
That involved in the present invention is a kind of new aqueous epoxy floor coating and its preparation technology, it is characterised in that the raw material auxiliary agent RS610 wetting dispersing agents, with anti-loose colour, anti-flash rusting, emulsifying, moistening effect.
That involved in the present invention is a kind of new aqueous epoxy floor coating and its preparation technology, it is characterised in that the raw material auxiliary agent DF681F defoamer for being used, with Diamond Search, without APEO the characteristics of.
That involved in the present invention is a kind of new aqueous epoxy floor coating and its preparation technology, it is characterised in that the raw material titanium dioxide for being used is nm-class rutile titanium dioxide.
That involved in the present invention is a kind of new aqueous epoxy floor coating and its preparation technology, it is characterised in that the raw material precipitated calcium carbonate for being used, its mesh number reach 2500 mesh and more than.
That involved in the present invention is a kind of new aqueous epoxy floor coating and its preparation technology, it is characterised in that the raw material super-fine talc for being used, its mesh number reach 1250 mesh and more than.
That involved in the present invention is a kind of new aqueous epoxy floor coating and its preparation technology:By appropriate deionized water and titanium dioxide, 801 strontium chromates, blanc fixe, super-fine talc, precipitated calcium carbonate, after mixing and stirring, add wetting dispersing agent, defoamer, scratch resistance auxiliary agent, grind after high-speed stirred 10min, after fineness is qualified, add aqueous epoxy curing agent, add remaining deionized water, it is qualified with alkali swollen thickener regulation viscosity, filter, go out finished product.First component and the use proportioning of component B, are formed, first component by its proportions:Component B=(1.0-1.2):1, it is that aqueous epoxy resins appropriateness is excessive, to improve the resistance to water and corrosion resistance of paint film.
A kind of new aqueous epoxy floor coating involved in the present invention and its preparation technology, using water as disperse medium, save substantial amounts of resource, eliminate fire risk during construction, reduce the pollution to air, operating environmental condition is improved, its coating adhesion is strong, also relatively good to base material caking property.
A kind of new aqueous epoxy floor coating involved in the present invention and its technical specification of preparation technology:
Embodiment 2:A kind of new aqueous epoxy floor coating involved in the present invention and its preparation technology, it is characterised in that be formulated by the mass fraction ratio of its raw material:First component:80 parts of aqueous epoxy resins, 20 parts of reactive diluent;Component B:25 parts of aqueous epoxy curing agent, 25 parts of deionized water, 0.2 part of RS610 wetting dispersing agents, 0.3 part of DF681F defoamer, 0.6 part of scratch resistance auxiliary agent, 0.15 part of A401 alkali swollen thickener, 5 parts of titanium dioxide, 2.5 parts of BGS phthalocyanine blues, 1.5 parts of 801 strontium chromate, 10 parts of precipitated calcium carbonate, 20 parts of blanc fixe, 10 parts of super-fine talc.
The testing result of embodiment:
The above, is only the preferable case study on implementation to the present invention, and without limiting it, any those skilled in the art can be changed or be replaced on an equal basis in the technology contents of the disclosure above to be changed.Every without departing from present invention, any modification, replacement made to above example according to the technical spirit of the present invention etc. all should be included within the scope of the present invention.
