Description
Technical field
The invention belongs to woodwork coating field, and in particular to a kind of bi-component woodcare paint and preparation method thereof.
Background technology
Woodcare paint refers to for the resinoid paint on woodwork specifically there is the kinds such as Polyester Paint, polyurethane paint.Woodcare paint
Generally can be divided into water paint and oil paint；Can be divided into high lac varnish, semi-matte paint, dumb light paint by glossiness；Can be divided into house by purposes
Tool paint, floor paint etc..Common oil paint has used organic solvent, there is pollution, can also burn, and is absolutely unsafe.And water paint
There is essential distinction with oil paint, aqueous woodware paint not only has the advantages that asepsis environment-protecting, odorlessness, volatilizable thing are few, and
With the characteristic for not firing not quick-fried high security and non yellowing, brushing surface is big；With the enhancing of people's environmental consciousness, water paint
Increasingly welcome by market.
Aqueous woodware paint is utilized and sanitary improvement for the reasonable of resource, all highly beneficial.But at present, due to list
The crosslink density of the film that component aqueous wooden ware is formed is not high, causes the final hardness of film not enough, and scratch resistance is poor and resistance toization
The performance for learning corrosion is general, and sealing effect is not ideal enough, and the bottleneck in its performance is difficult to break through；And the bi-component wood of existing research and development
Device paint is not mature enough, and not enough, lacquer painting easily turns yellow, performance extremely unstable for its hardness and adhesive force.On the other hand, the custom of construction and
Intrinsic notion gap to painting also counteracts that the popularization and application of water-borne wood coating, particularly require higher occasion, such as
Furniture manufacturing industry and industrial coating streamline.Therefore, in order to meet the requirement in market, it is badly in need of the more preferable bi-component water of exploitation performance
Property woodwork coating, with improve the woodenware such as furniture coating select.
The content of the invention
Present invention aim to overcome that the deficiencies in the prior art, there is provided a kind of bi-component woodcare paint and preparation method thereof, with
It is the hardness and poor adhesive force of aqueous woodware paint, perishable in solving prior art, the problems such as Market Selection is limited.
In order to realize foregoing invention purpose, the technical solution used in the present invention is as follows：
A kind of bi-component woodcare paint, including mian paint coating and the component of firming agent two；
The mian paint coating includes the composition of following weight/mass percentage composition：
The firming agent includes the composition of following weight/mass percentage composition：
The bi-component woodcare paint that the present invention is provided, passes through synergistic between the various composition that its mian paint coating and firming agent are included
Effect, not only improves the lacquer painting function of playing mian paint coating, and solidification effect of the firming agent to lacquer painting is enhanced again, finally makes this pair
Component woodcare paint has crosslink density big, and hardness is high, the function such as quick-drying, and it is difficult burn into discoloration, and construction tolerance is good,
It is particularly suited for the application of top-grade furniture and the incrustation finishing of advanced material.
On the other hand, the present invention also provides a kind of preparation method of above-mentioned bi-component woodcare paint.The preparation method include as
Lower step：
The formula of the mian paint coating and firming agent according to above-mentioned bi-component woodcare paint weighs respectively each component materials；
By the aqueous pu dispersions, hydroxyl acrylic emulsion, delustering agent, coalescents, substrate wetting agents, rheology
Auxiliary agent, thickening agent, defoamer, preservative, antibacterial, cross-linking agent and water make the mian paint coating；
The isocyanates, Allyl carbonate, dehydrant and silane coupler are made into the firming agent.
The bi-component woodcare paint preparation method that the present invention is provided, process is simple, it is easy to operation and control process conditions, cost
It is low, environmentally safe.And the bi-component woodcare paint obtained with the method has crosslink density big, hardness is high, quick-drying, is difficult
The features such as burn into changes colour.
Specific embodiment
In order that the technical problem to be solved in the present invention, technical scheme and beneficial effect become more apparent, below in conjunction with
Embodiment, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only to explain
The present invention, is not intended to limit the present invention.
The embodiment of the present invention provides a kind of new aqueous wood lacquer with double components, including two kinds of groups of mian paint coating and firming agent
Point；Mian paint coating includes the composition of following weight/mass percentage composition：
Firming agent includes the composition of following weight/mass percentage composition：
By synergistic effect between the various composition that mian paint coating and the firming agent are included, performance mian paint coating is not only improved
Lacquer painting function, solidification effect of the firming agent to lacquer painting is enhanced again, finally make the bi-component woodcare paint have crosslink density big,
Hardness is high, the function such as quick-drying, and it is difficult burn into discoloration, and construction tolerance is good, be particularly suited for top-grade furniture application and
The incrustation finishing of advanced material.
Specifically, in an embodiment of the present invention, the mass percent of the aqueous pu dispersions can preferably 20%,
22% or 25%.Aqueous pu dispersions are a kind of dispersions of polyurethanes for not containing emulsifying agent, its point in film forming procedure
It is in regular arrangement between subchain and between ionic group, not only exists between electrostatic interaction and hydrogen bond force, and molecule and also occur
Cross-linking reaction, forms network structure.Due to the presence without emulsifying agent, the aqueous pu dispersions are to mechanical agitation, heating
Or the sensitivity of dilution is less and big into film hardness, adhesion is strong.Contain in delustering agent quality percentage provided in an embodiment of the present invention
It is optimal to the film hardness and adhesion of the bi-component woodcare paint in the range of amount.
