Description
Technical field
The invention belongs to complexing agent technical fields, and in particular to inhibit what is spread in tannin hydrotropism's woodcare paint in timber to help
Agent and its application method.
Background technology
Tannin is also known as tannic acid, is the water-soluble yellow that is generated in growing process to dark-brown polyphenol compound.
Traditional oil paint is to inhibit tannin into finishing coat by using the shielding action of high rigidity, high crosslink density seal coat
Diffusion；Water paint is by way of repeatedly brushing one-component primers (i.e. by increasing coating layer thickness, extending tannic acid diffusion
The mode in path), avoiding influences caused by tannin free diffusing is finishing coat.In recent years, it is (mainly organic to wave to come from environmental protection
Send out object discharge capacity, VOC) and health consciousness both sides pressure is continuously improved, high closeness solvent wood coatings answer
With fewer and fewer, the application of aqueous environment protection woodwork coating is paid more and more attention.But due to water-borne wood coating membrane formation mechanism
Limitation, so the crosslinking reaction may not occur in film forming procedure for aqueous woodware paint, cause it is dry after coating hardness it is not high, to list
The inhibition rather spread is poor.In order to solve the problems, such as that mono-component aqueous priming paint is poor to tannin sealing effect, at present using more
The mode of secondary construction to increase the method for seal coat dry thickness achievees the effect that tannin is inhibited to spread to finishing coat.But this
It is kind simple to rely on that increase the construction technology that construction times prevent tannin from spreading not only very cumbersome, also add manpower and material at
This.In order to solve the problems, such as that present aqueous wooden ware seal coat needs repeatedly construction, Dow Chemical company to be proposed new one
For Avanse products, phosphoric acid ester monomer is introduced into polymer molecule.The intramolecular that is occurred by phosphoric acid ester monomer, point
Self-crosslinking reaction between son moderately increases the compactness extent of paint film, effectively limits the migration of tannin.But it was synthesizing
Cheng Zhong, the structure of phosphoric acid ester monomer and its in polymer molecule the control of distribution situation it is more difficult.Therefore, exploitation is a kind of
Environmental-friendly, easy to operate, the moderate, new material that can effectively inhibit tannin to spread or new additive agent are to solve existing water
Property woodcare paint inhibit tannin diffusion problem key.
