Abstract
The invention relates to a waterborne epoxy colorful floor paint and a colored waterborne epoxy resin gel particle. The colored waterborne epoxy resin gel particle is prepared from two groups of gel materials by twice gelling reaction. The colored waterborne epoxy resin gel particle prepared from waterborne epoxy resin is dispersed in waterborne epoxy resin varnish, and after curing, the waterborne epoxy colorful floor paint can be formed. The coating can be used between a waterborne floor coating material and a priming paint so as to make the floor paint reach a vivid granite-like decorative effect. The paint film has the characteristics of high hardness, water resistance, chemical resistance, and high adhesion, etc. And the production process is simple, and is suitable for large scale production.
Description
Technical field
The invention belongs to terrace decoration material field, particularly colorful floor paint of water-base epoxy and preparation method thereof.
Background technology
Water-soluble colorful coating mainly take vinylformic acid synthetic resin emulsion as tackiness agent since be born the nineties, and the application that this kind of coating has limited it in the deficiency aspect hardness, water-fast, chemicals-resistant is only confined to construction wall field.And terrace field has no the figure of water-soluble colorful coating always.
People, more and more ask most and decorate today personalized, diversification, the Application Areas of expanding water-soluble colorful coating seems very necessary.Current, floor paint artificial granite decorative effect mainly contains two kinds of technology, and the one, add colorful quartz sands, the 2nd, add colored sliver.Add colorful quartz sands and cannot reach grouan effect true to nature because particle is less, adding sliver has not only increased the difficulty of construction but also has increased film thickness, and sliver itself is expensive simultaneously, so cost is higher.
Summary of the invention
For the problems referred to above of prior art, the invention provides the colorful floor paint of a kind of water-base epoxy, this coating, in the middle of water-based terrace coating material finish paint and priming paint, makes floor paint have artificial granite decorative effect more true to nature.
For achieving the above object, the present invention includes following technical scheme:
For a color aqueous epoxy resin gel particle for the colorful floor paint of water-base epoxy, it adopts following methods to prepare:
Step 1: water, auxiliary agent, rheology control agent are dropped into 1000～2000 revs/min of dispersed with stirring 10-15 minute in high speed dispersor;
Step 2: drip potassium hydroxide solution and neutralize, make pH value reach 8;
Step 3: with color paste toning, vacuumize elimination bubble, form colored protection glue;
Step 4: after aqueous epoxy resins is mixed with solidifying agent, slowly join in toning protection glue, stir;
Step 5: add boric acid aqueous solution, stir;
Step 6: add calcium chloride water, gelation 0.5～2 hour;
Step 7: adopt rotating blade to turn and cut granulation or carry out granulation by screen cloth, gained particle completed aqueous epoxy resins crosslinking curing through 7～8 hours again, obtained color aqueous epoxy resin gel particle.
Color aqueous epoxy resin gel particle as above, preferably, described each composition and proportioning are in weight part:
Color aqueous epoxy resin gel particle as above, preferably, described auxiliary agent is: wetting agent 1-2 weight part, defoamer 2-5 weight part and sterilant 2-5 weight part.
Color aqueous epoxy resin gel particle as above, preferably, described rheology control agent is carbomer 3-7 weight part and 4 % by weight konjaku aqueous solution 25-50 weight parts.
Color aqueous epoxy resin gel particle as above, preferably, described aqueous epoxy resins is E type epoxy resin.
Color aqueous epoxy resin gel particle as above, preferably, described E type epoxy resin is that molecular resin amount is 380-30000 by dihydroxyphenyl propane (two (4-hydroxy phenyl) propane of 2,2-) and the synthetic simple linear polymer of epoxy chloropropane polycondensation in alkaline medium.
Color aqueous epoxy resin gel particle as above, preferably, described aqueous epoxy resins is that E type epoxy resin is E-51 type epoxy resin.
Color aqueous epoxy resin gel particle as above, preferably, the average oxirane value 51/100=0.51 of described E-51 type epoxy resin, oxirane value N/100 is 0.48-0.54.
On the other hand, the invention provides the colorful floor paint of a kind of water-base epoxy, it is comprised of aqueous epoxy resins and the as above color aqueous epoxy resin gel particle that is scattered in wherein.
Again on the one hand, the invention provides the preparation method of the colorful floor paint of a kind of water-base epoxy, the method comprises: color aqueous epoxy resin gel particle as above is scattered in aqueous epoxy resins varnish, applies this varnish mixed solution, through solidifying to form floating coat on priming paint; On floating coat, apply finish paint, after solidifying, obtain the colorful floor paint of water-base epoxy.
Preparation method as above, preferably, the concrete steps of described method are:
Step 1: after mixing with 0.8-1.2 weight part solidifying agent with 0.8-1.2 weight parts water epoxy resin again with the color aqueous epoxy resin gel mix particles of 5-10 weight part;
Step 2: the varnish mixed solution of coating step 1 preparation on priming paint, solidify 15-48 hour, form floating coat;
