Abstract
A kind of colorful floor paint of water-base epoxy and color aqueous epoxy resin gel particle, this color aqueous epoxy resin gel particle uses two groups of gelatinous materials, make through twice gel reaction, the color aqueous epoxy resin gel particle dispersion that aqueous epoxy resins is made in aqueous epoxy resins varnish, through solidifying to form the colorful floor paint of water-base epoxy.This coating is used for, in the middle of water-based terrace coating material finish paint and priming paint, making floor paint have artificial granite decorative effect more true to nature.Its paint film has the feature such as high rigidity, water-fast, chemicals-resistant, high adhesive force, and its production technique is simple, is suitable for carrying out 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 since being born from the nineties main with vinylformic acid synthetic resin emulsion for tackiness agent, the application that this kind of coating deficiency in hardness, water-fast, chemicals-resistant limits it is only confined to construction wall field.And floor field has no the figure of water-soluble colorful coating always.
More and more ask most today of decoration personalization, diversification people, the Application Areas expanding water-soluble colorful coating seems very necessary.Current, floor paint artificial granite decorative effect mainly contains two kinds of technology, and one is add colorful quartz sands, and two is add colored sliver.Add colorful quartz sands and cannot reach grouan effect true to nature because particle is less, add sliver and not only add the difficulty of construction but also add film thickness, 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 is used for, in the middle of water-based terrace coating material finish paint and priming paint, making 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, forms colored protection glue;
Step 4: after being mixed with solidifying agent by aqueous epoxy resins, slowly joins in toning protection glue, stirs;
Step 5: add boric acid aqueous solution, stirs;
Step 6: add calcium chloride water, gelation 0.5 ~ 2 hour;
Step 7: employing rotating blade carries out turning to be cut granulation or carry out granulation by screen cloth, and 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 with parts by weight:
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 epoxy chloropropane simple linear polymer that polycondensation is synthesized in alkaline medium.
Color aqueous epoxy resin gel particle as above, preferably, described aqueous epoxy resins is E type epoxy resin is E-51 type epoxy resin.
Color aqueous epoxy resin gel particle as above, preferably, described E-51 type epoxy resin average epoxy value 51/100=0.51, 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 made up of aqueous epoxy resins and the as above color aqueous epoxy resin gel particle be 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: by color aqueous epoxy resin gel particle dispersion as above in aqueous epoxy resins varnish, priming paint applies this varnish mixed solution, through solidifying to form floating coat; Floating coat applies finish paint, after solidification, obtains the colorful floor paint of water-base epoxy.
Preparation method as above, preferably, the concrete steps of described method are:
Step 1: the color aqueous epoxy resin gel mix particles with 5-10 weight part again after mixing with 0.8-1.2 weight part solidifying agent with 0.8-1.2 weight part aqueous epoxy resins;
Step 2: the varnish mixed solution that on priming paint prepared by coating step 1, solidification 15-48 hour, forms floating coat;
Step 3: apply finish paint on floating coat prepared by step 2, obtain the colorful floor paint of water-base epoxy after solidification.
Another aspect, the invention provides the colorful floor paint of a kind of water-base epoxy, and it adopts method as above to prepare.
The gordian technique of the colorful floor paint of water-base epoxy is color aqueous epoxy resin gel particle, and its performance requriements has good formability, stronger hardness and water tolerance.If only use aqueous epoxy resins and corresponding solidifying agent to prepare gel particles, its gelation rate is slow, usually needs more than 8 hours, and after drying, hardness is high, and be difficult to form thin slice, surface irregularity, corner is easily curling.The present invention uses two groups of gelatinous materials, and twice gel reaction occurs in pelletization.First, there is complex reaction in the carbomer in gel mixture, konjaku under the effect of boric acid, calcium chloride, forms snappiness gelinite in 0.5-2 hour, and this colloid elasticity is high, plasticity-is strong, be easy to section, granulation, but hardness is low, water-fast, alkali resistance is poor.After this gelinite granulation, intragranular aqueous epoxy resins and corresponding solidifying agent proceed crosslinking reaction, i.e. two-step gelation reaction, final formation plural gel body, significantly reduce the water-absorbent of water-soluble polymer gel after cross-linked epoxy resin gel drying in this gelinite and there is stronger hardness, solve the problem of the water-fast difference of water-soluble colorful coating, and once shaped particle is easily destroyed and the problem of colour mixture.
Form the colorful floor paint of water-base epoxy after above-mentioned color aqueous epoxy resin gel particle dispersion being solidified in aqueous epoxy resins varnish, it is applicable to floor paint floating coat.Its paint film has the feature such as high rigidity, water-fast, chemicals-resistant, high adhesive force, and its production technique is simple, is suitable for carrying out scale production.
