Description
Technical field
The invention belongs to fine new material technology field more particularly to a kind of clear priming paint of the anti-tannic acid of aqueous one-component and its
Preparation method.
Background technique
With the improvement of people's environmental awareness, house ornamentation water paint surely can be increasingly by everybody welcome.Water paint is
Using water as the Environmentally friendly coatings of decentralized medium, but since lumber fibre has hydrophily, the tannic acid in timber is same
With hydrophily, therefore, using water paint as timber priming paint in the case where, if the anti-tannic acid ability of priming paint is poor, be easy
The phenomenon that tannic acid in existing timber, which is migrated to film coated surface, causes priming paint paint film hair crow unlimpid, and timber turns yellow after finish,
Seriously affect the quality of product.In addition, there is also defects not easy to polish after drying for existing woodenware priming paint.
Therefore, it for poor, the not easy to polish problem of priming paint paint film that solves the anti-tannic acid ability of priming paint, studies novel aqueous
Priming paint is particularly important.
Summary of the invention
The purpose of the present invention is in view of the defects existing in the prior art and insufficient, and it is clear to provide a kind of anti-tannic acid of aqueous one-component
Priming paint and preparation method thereof, the clear priming paint have anti-tannic acid ability strong, can effectively prevent tannic acid migration, gained priming paint paint film
It is limpid not send out crow, it is easy to polish, the characteristics of flavescence after finish.
To achieve the goals above, the present invention adopts the following technical scheme:
The clear priming paint of a kind of anti-tannic acid of aqueous one-component, by priming paint and water according to weight ratio (70-100): (5-10) mixing
It forms, wherein the priming paint is by including that each component of following parts by weight is prepared:
Wherein, emulsion acrylic resin preferred viscosities≤1000cP, solid content >=40%, pH value are the product of 7-9；Selfing
Connection type emulsion acrylic resin preferred viscosities≤500cP, solid content >=40%, pH value are the product of 7-9, such as acrylic resin
The S5539 product of Shanghai Zhanchen Paint Co., Ltd. can be used in lotion；Bugle can be used in self-cross linking type emulsion acrylic resin
The S5540 product of occasion coating Co., Ltd.
Inventor has found that the clear priming paint being individually prepared using emulsion acrylic resin as primary raw material is main under study for action
It there is grinability difference；And the clear priming paint being individually prepared using self-cross linking type resin emulsion as primary raw material, it is main
It 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 the amount ratio both controlled, when being about 1:1, resulting clear priming paint has optimal sealing performance, Neng Gouyou
Effect prevents tannic acid from migrating, and in addition to this, paint film also has splendid sanding property.
Specifically, major ingredient of the invention is emulsion acrylic resin and self-cross linking type emulsion acrylic resin, they have
There is the features such as extraordinary endurance and anti-caking, transparency is high, and scratch resistance is good, it is anti-to greatly improve aqueous one-component
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
The characteristic for belonging to ion complexation, phenolic hydroxyl group a large amount of in the metal ion and tannic acid in emulsion acrylic resin is complexed,
A kind of five yuan of highly stable chela ring structures are formed between catechol base and metal ion, to form one layer on material
Fine and close paint film, so as to effectively prevent the migration of tannic acid.Selected self-cross linking type emulsion acrylic resin drying speed, polishing
Property is good.By the way of emulsion acrylic resin and self-cross linking type emulsion acrylic resin blending, not only gained the anti-tannin of paint film
Acid is had excellent performance, and dry easy to polish rapidly, is conducive to the coating efficiency etc. for improving assembly line.
Preferably, when the weight ratio of the self-cross linking type emulsion acrylic resin and emulsion acrylic resin is 1:(1-
1.2) when, clear priming paint of the present invention has optimal effect, and anti-tannic acid performance is best, and coating does not send out crow, and cover is constant
Huang, and good leveling property of constructing, are easy to polish.
In order to further ensure that the effect of clear priming paint, thickener, coalescing agent, levelling are also added in the clear priming paint
