Agent and remaining water, stir 5～10 minutes with the stir speed (S.S.)s of 300～500 revs/min, make uniform sizing material；
(3) preparation aqueous titanium dioxide slurry: choose each raw material of preparation aqueous titanium dioxide slurry by quantitative relation, first take dispersant, gold
Red stone titanium dioxide, aerosil, preservative and ultramarine, add part water, stir with the stir speed (S.S.) of 1200～1500 revs/min
Mix 20～25 minutes, be dispersed to fineness qualified after, add in remaining water, make aqueous titanium dioxide slurry；
(4) the aqueous titanium dioxide slurry that step (3) is made is joined in the slurry that step (2) is made, with 400～500 revs/min
Stir speed (S.S.) stir 20～25 minutes, prepare first component；
(5) by fast with the stirring of 400～500 revs/min to hydrophilic aliphatic polyisocyanate and propylene glycol methyl ether acetate
Rate stirs 10～15 minutes, prepares component B；
(6) choose first component, component B and water by quantitative relation, first add water to first component stirs evenly, add second group
Part stirs evenly, and i.e. prepares the double-component aqueous woodenware white finish paint of composite multifunction after standing.
Further, particularly as follows: press following construction proportioning in step (6), first component: component B: water is 100:20～25:
10～20, first appropriate water is added first component and first stir, after being subsequently adding component B, then stir, stand
Spray after 10～15 minutes or brush.
In above-mentioned steps:
In step (1) and step (2), the addition of part water accounts for this step water gross mass 70～80%；In step (3)
The addition of part water accounts for the 60～70% of this step water gross mass.
Present invention have the advantage that
(1) the double-component aqueous woodenware white finish paint of the composite multifunction in the present invention, gives paint film excellent antibacterial except aldehyde merit
Can, do not contain the organic exhaust gas such as formaldehyde, health environment-friendly, spot-resistant；
(2) the double-component aqueous woodenware white finish paint materials of composite multifunction of the present invention rationally, moderate cost, every physical property
Can show outstanding, apply performance good；
(3) due to the fact that have employed exclusively for improve water-borne wood coating spot-resistant and design except aldehyde performance compound
Modified self-crosslinking acrylate copolymer, for improving the compatibility and the stability of product；
(4) in view of cost and antibacterial effect of formaldehyde, the present invention adds the model of Rhom and Hass of U.S. production and is
The specific function auxiliary agent eliminating formaldehyde that the biocide mildewcide of ROCIMA 342 and Sa Masuo company of Germany produce, model is
SAMASO FA16, cost advantage is obvious, adjusts through formulation cost, and resistant product similar with market compares discoverys, and cost is flat
All declining 2～3 yuan of per kilograms, the most high-grade, cost declines the most；The reason that its cost declines, is to add some spies
Different organic silicon emulsion or hydrophobic auxiliary agent realize, and both market prices rear are high, and dosage is the most more, scrubbing resistance and spot-resistant
Effect is not the most lasting, and basic components cost increases substantially, and these common like products the most do not possess antibacterial except aldehyde function, city simultaneously
Field synthesized competitiveness is general.

The performance test of Part II composite multifunction of the present invention double-component aqueous woodenware white finish paint
Use the composite multifunction double-component aqueous woodenware white finish paint made in the above embodiment of the present invention 1～3, use this
The detection method of field routine detects the conventional physico-chemical properties of this composite multifunction double-component aqueous woodenware white finish paint, specific performance
Index is as shown in table 1 below.
The double-component aqueous woodenware white finish paint of table 1 embodiment of the present invention 1～3 preparation and the traditional performance of film
From table 1 it follows that the properties of composite multifunction double-component aqueous woodenware white finish paint prepared by the present invention
Index all reaches or is better than standard GB/T/T 23999-2009.
The composite multifunction double-component aqueous woodenware white finish paint in above-described embodiment 1-3 is used to carry out spot-resistant performance examination
Testing, process of the test and result are as follows:
Coating application test (one): with hairbrush at 0.6m3The whole outer surface of experiment plank is coated with above-described embodiment 1～3
In composite multifunction double-component aqueous woodenware white finish paint 2 road made, per pass repainting time is 6～8 hours, coating dry film 1～
2mm, after room temperature maintenance 5 days, drips various spot sources on the paint film of vertical hanging, the most as shown in fig. 1, spot source from a left side to
The right side includes successively: dark soy sauce, vinegar, coffee, black tea, blue ink, edible oil, water solublity white carbon black, alcohol-soluble white carbon black, lipstick, ball pen,
Wax crayon (5 kinds of colors).Normally clean at coating surface after getting wet with wet towel, the double group of composite multifunction in embodiment 1～3
The spot-resistant of part aqueous wooden ware white finish paint is cleaned test result and is seen shown in Fig. 2.
Test comparison result from Fig. 2 is it can be seen that under the conditions of the same spot of same ground, in embodiment 1～3
The composite multifunction double-component aqueous woodenware white finish paint the made double-component aqueous woodenware white finish paint common with on market (refers generally to
Conventional products adds some special organic silicon emulsions or hydrophobic auxiliary agent realizes, but its DeGrain and the most lasting) phase
Ratio, only need to wet rag just can by these greasiness removals, make woodenware surface recovery to former state, and common double-component aqueous woodenware
White finish paint does not then reach this easy scrub effect, leaves obvious vestige or paint film because cleaning and occurring damaging in various degree.
Additionally, due to the fact that and have employed exclusively for improving aqueous wooden ware white finish paint spot-resistant performance and compound changing of designing
Property self-crosslinking acrylic polymer because by great many of experiments, elastene 3030 self-crosslinking acrylic polymer is carried out multiple
Close modification.For for its special structure of elastene 3030, intermediate based on elastene 3030, introduce hydrophilic
Property coalescents DPM (dipropylene glycol methyl ether) and oil loving coalescents DPNB (dipropylene), and add suitable
Amount hydrophilic propylene glycol, can improve elastene 3030 in aqueous double-component woodcare paint with AC 27401 aqueous hydroxyl
Base acrylate copolymer, simultaneously actual join during paint with hydrophilic aliphatic polyisocyanate Bayhydur XP 2655 energy
There is the more preferable compatibility, do not interfere with the chemical reaction of the esterification of AC27401 Yu Bayhydur XP 2655, thus formed more
Fine and close paint film.Elastene 3030 itself has the resistance to hydrophilic stains performance of excellence and resistance to hydrophobic stains performance simultaneously,
Minimum film formation temperature can only need a small amount of coalescents i.e. to can reach excellent with self-crosslinking under zero degree, room temperature in basic components
Different filming performance, thus cost advantage is obvious, adjusts through formulation cost, resistant product similar with market compares discovery,
Cost averagely declines 1～2 yuan of per kilogram, the most high-grade, and cost declines the most；The reason that its cost declines, is to add
Some special organic silicon emulsions or hydrophobic auxiliary agent realize, and both market prices rear are high, and dosage is the most more, scrubbing resistance and resistance to
The effect of spot is not the most lasting, and basic components cost increases substantially, and these other manufacturers of going together the most at present are using
Method.
