Description
Technical field
The invention belongs to fine new material technology field, particularly relate to a kind of clear priming paint of the anti-tannic acid of aqueous one-component and
Preparation method.
Background technology
With the raising of people's environmental consciousness, house ornamentation water paint can increasingly be welcome by everybody surely.Water paint is
Environmentally friendly coatings with water as decentralized medium, but owing to lumber fibre has hydrophily, the tannic acid in timber is same
There is hydrophily, therefore, in the case of using water paint as timber priming paint, if the anti-tannic acid ability of priming paint, easily go out
Tannic acid in existing timber migrates to film coated surface, and to cause priming paint paint film to send out crow unlimpid, the phenomenon that after finish, timber turns yellow,
Have a strong impact on the quality of product.Additionally, existing woodenware priming paint there is also the defect being difficult to polishing after being dried.
Therefore, in order to solve priming paint anti-tannic acid ability, priming paint paint film is difficult to the problem of polishing, studies novel aqueous
Priming paint is particularly important.
Content of the invention
Defect that the purpose of the present invention exists for prior art and deficiency, provide a kind of anti-tannic acid of aqueous one-component clear
Priming paint and preparation method thereof, it is strong that this clear priming paint has anti-tannic acid ability, can effectively prevent tannic acid from migrating, gained priming paint paint film
Limpid do not send out crow, easily polish, the feature not turned yellow after finish.
To achieve these goals, the present invention adopts the following technical scheme that
A kind of clear priming paint of the anti-tannic acid of aqueous one-component, by priming paint and water according to weight ratio (70-100): (5-10) mixes
Forming, wherein, described priming paint is prepared by each component including following weight portion:
Wherein, emulsion acrylic resin preferred viscosities≤1000cP, solid content >=40%, pH value is the product of 7-9；Selfing
Connection type emulsion acrylic resin preferred viscosities≤500cP, solid content >=40%, pH value is the product of 7-9, such as acrylic resin
Emulsion can use the S5539 product of Shanghai Zhanchen Paint Co., Ltd.；Self-cross linking type emulsion acrylic resin can use Bugle
The S5540 product of occasion coating Co., Ltd.
Inventor finds under study for action, the clear priming paint being individually prepared from emulsion acrylic resin for primary raw material, main
The problem of grinability difference to be also existed；And the clear priming paint being individually prepared from self-cross linking type resin emulsion for primary raw material, main
The problem that there is anti-tannic acid difference.Present inventors have unexpectedly found that, when by emulsion acrylic resin and self-cross linking type resin emulsion
When being used in mixed way, and when the amount ratio controlling the two is about 1:1, the clear priming paint of gained has optimal sealing property, Neng Gouyou
Effect prevents tannic acid from migrating, and in addition, paint film also has splendid sanding property.
Specifically, the major ingredient of the present invention is emulsion acrylic resin and self-cross linking type emulsion acrylic resin, and they have
Having extraordinary endurance and anti-caking, transparency is high, the features such as scratch resistance is good, drastically increases aqueous one-component and resists
The transparency of the clear priming paint of tannic acid and richness etc..Wherein, selected emulsion acrylic resin makes full use of vegatable tannin acid and gold
Belonging to the characteristic of ion complexation, by the metal ion in emulsion acrylic resin, substantial amounts of phenolic hydroxyl group is complexed with tannic acid,
Form a kind of five yuan of highly stable chela ring structures between catechol base and metal ion, thus form one layer on material
Fine and close paint film such that it is able to effectively prevent the migration of tannic acid.Selected self-cross linking type emulsion acrylic resin drying speed, polishing
Property is good.Use the mode of emulsion acrylic resin and self-cross linking type emulsion acrylic resin blending, the not only anti-tannin of gained paint film
Acid excellent performance, and it is dried easily polishing rapidly, be conducive to improving the coating efficiency etc. of streamline.
Preferably, when the weight of described self-cross linking type emulsion acrylic resin and emulsion acrylic resin is than for 1:(1-
1.2) when, clear priming paint of the present invention has optimal effect, and anti-tannic acid performance is optimal, and coating does not send out crow, and cover is constant
Huang, and construction good leveling property, it is easy to polishing.
In order to further ensure that the effect of clear priming paint, described clear priming paint thickener, coalescents, levelling are also added with
The auxiliary agents such as agent, bactericide, defoamer.
