Technical field
The present invention relates to water-borne wood coating fields, and in particular to a kind of suitable for the aqueous of a variety of wood substrate coatings
Wooden ware sealing priming paint and preparation method thereof.
Background technique
Since the wood substrate covered in woodwork coating is many kinds of, main Wood in Common Use includes beech, oak, water song
The natural sawn timber such as willow, pine, birch, maple, cherry, black walnut further includes density board, glued board and particieboard et al.
Make plate etc..As timber itself, chemical composition is extremely complex, the basic element average content of ovendriedwood are as follows: carbon
50%, hydrogen 6.4%, oxygen 42.6%, nitrogen 1%.Main component includes cellulose, hemicellulose, lignin and wooden extract
(tannic acid, grease, essence, pigment, alkaloid etc.).Due to the presence of Wood abstract, usually contained in the lumen of timber
The substances such as resin, natural gum, tannic acid, pigment, volatility oils, water, if woodenware priming paint to the closure effect of timber not
Well, the defects of being easy to cause paint film to spit oil, discoloration.
Not long ago, industry is for ground bleeding problem, there are two ways to generally taking: first is that using through particular molecule knot
The cation type emulsion of structure design prepares aqueous sealing primer as film forming matter, second is that directly at the clear bottom of standard aqueous woodenware
Anti- tannin acid assistant is added in paint formula, and (analog assistant usually contains water solubility and contains aluminium, magnesium, zirconium, zinc compound, can be with wood
The generation metal complex such as pigment, tannic acid in material is deposited on paint film bottom at salt and no longer migrates), to play certain
Bleeding sealing effect.Chinese invention patent CN 103642342B on this basis using have good impervious color effect it is positive from
There is the collocation of subtype lotion the impervious color auxiliary agent of excellent metal complexing capability to play synergistic effect, use waterborne cation third
1 kind in olefin(e) acid lotion, waterborne cation modified acrylic acid terpolymer dispersion or waterborne cation epoxy resin ester lotion or
Main film forming substance of the mixture of more than two kinds as coating, while being aided with acetic acid zirconium, 20wt% magnesium chloride brine, aluminium
1 kind in zirconium coupling agent, chlorination hydroxyl aluminium, 20wt% zirconium sulfate aqueous solution, 20wt% zinc sulfate solution or titanate coupling agent
Or mixture of more than two kinds is prepared for a kind of aqueous impervious color woodenware clear bottom of energy storage-stable as impervious color auxiliary agent
Paint.But this cationic seal coat is often applied with the aqueous wooden ware using the preparation of conventional anion aqueous acrylic emulsion
Expect incompatible, needs to have special equipment in the construction application in product development, production link and downstream, otherwise easily
There is raw slag, the case where paint finishing is even thoroughly blocked and scrapped by gel, at the same there is also hardness establish it is slow, bad
