Abstract
The invention discloses an anti-blocking water-based wood transparent finish paint used under high-temperature high-humidity conditions. The finish paint comprises the following components in percentage by weight: 5.1-26.4% of deionized water, 1-3% of dipropylene glycol monobutyl ether, 1-4% of dipropylene glycol monomethyl ether, 0.1-0.5% of water-based defoaming agent, 0.3-0.6% of water-based leveling agent, 0.1-0.3% of water-based bactericidal mildew preventive, 65-75% of acrylic acid emulsion, 5-10% of anti-blocking agent, 0.2-0.5% of hand feeling agent and 0.3-1% of thickener. The finish paint solves the problems in the prior art by adopting the core-shell-structure emulsion system. The finish paint has higher blocking resistance, and helps the water-based wooden toy paint in popularization. In the biggest wooden toy production base in China in Yunhe of Lishui in Zhejiang Province, the application conditions for the water-based wooden toy paint are poor, and the paint is basically naturally dryied. Compared with the oil-based paint, the water-based paint can easily have the problem of product blocking.
Description
Technical field
The invention belongs to water-borne wood coating formula technique field.
Background technology
At present, market being sold aqueous wooden ware clear finish product, temperature 25 degree, relative humidity is

It is that more than 25 degree or humidity is more than 75% when temperature, after completing application, stacks under above-mentioned pressure, past
Toward adhesion problems occurs, thus affect water paint construction application performance, affect Waterborne wood to a certain extent
Device paint popularization.It is contemplated that raising aqueous woodware paint is under the conditions of hot and humid, tolerance of constructing,
Thus promote oil paint to turn water paint work.
Summary of the invention
It is an object of the invention to provide a kind of tissue adhesion aqueous transparent face of application under the conditions of hot and humid
Paint formula, solve present in prior art existing aqueous coating formulation temperature more than 25 degree or
Humidity more than 75% under the conditions of construct, the problem that water paint paint film is susceptible to adhesion situation.
The technical solution adopted in the present invention is, the tissue adhesion aqueous wooden ware of application under the conditions of hot and humid
Clear finish formula, including percentage by weight 5.1%-26.4% deionized water, 1%-3% dipropylene,
1%-4% dipropylene glycol methyl ether, 0.1%-0.5% aqueous defoamer, 0.3%-0.6% aqueous levelling agent,
0.1%-0.3% aqueous biocide mildewcide, 65%-75% acrylic emulsion, 5%-10% antiblocking agent,
0.2%-0.5% hand feeling agent and 0.3%-1% thickening agent.
The using method of inventive formulation is spary twice, and first brushing amount is 1 ± 0.1g/dm2,
Second is brushed after 24 hours；Second quantity for spray is 0.8 ± 0.1g/dm2, tests after placing 7 days.
The production technology of inventive formulation is to add percentage by weight 10.1% deionization the most while stirring
Water, 2% dipropylene, 3% dipropylene glycol methyl ether, 0.3% aqueous defoamer, 0.4% aqueous levelling agent,
0.1% aqueous biocide mildewcide, 0.4% hand feeling agent, 0.2% waterborne preservative, obtain pre-dispersed slurry；
Add percentage by weight 75% acrylic emulsion in another one cylinder, 8% antiblocking agent obtains mixed liquor
One；
Under stirring, pre-dispersed slurry is added in mixed liquor one, obtains mixed liquor two；
Under low whipping speed 300～400r/min, duration 20～25 minutes states, it is slowly added dropwise into weight hundred
Proportion by subtraction 0.5% thickening agent, adjustment viscosity to 60-70KU.
The invention has the beneficial effects as follows employing core-shell emulsion system, solve the problems of the prior art.
Improve tissue adhesion performance, help aquosity wooden toy paint to promote；Because producing at Largest In China wooden toy
Base Lishui of Zhejiang cloud and, aquosity wooden toy paint application condition is poor, is substantially natural drying.
Compared with oil paint, in plum rain season (temperature is higher than 25 degree or humidity is more than 85%), water paint pole
Easily there is product adhesion problems.
The present invention selects quick-dry type water-based emulsion on body material, on formula designs, uses fast stem body
System, successfully accelerates moisture release.Meanwhile, play cross-linking reaction at coating surface, form dense coating, right
Tissue adhesion plays a key effect.
