Description
Technical field
The present invention relates to a kind of aqueous woodware paint auxiliary agent, which passes through acid-base function, complexing and chemical reaction three
Kind mode of action collaboration inhibits tannic acid diffusion.
Background technique
Traditional solvent wood coatings are gradually replaced by environmental-friendly aqueous woodware paint.Due to solvent type and aqueous
Woodcare paint causes (especially white in aqueous woodware paint in various differences such as raw material selection, formula design, drying principles
Or light aqueous woodware paint) construction, occur various new problem in use process, typical problem such as, aqueous wooden ware
It is substantially lower without crosslinking or the degree of cross linking between paint molecular resin, cause it is dry after woodcare paint paint film is softer, poor mechanical property,
The problem of anti-pollution characteristic is short of；In work progress, the tannic acid in timber is dissolved in water, and then free diffusing causes in water paint
Paint film discoloration problem.The discoloration problem because of caused by tannic acid free diffusing in aqueous woodware paint is to enable formula design work
Cheng Shi and construction personnel feel more the problem of headache.
Tannic acid is a kind of water-soluble phenolic substance generated during arboreal growth, is contained in the timber of solid wood furniture
There is tannic acid.For aqueous woodware paint when constructing on solid wood, the tannic acid in timber is soluble in water, and water is gradually diffused into from timber
Inside property woodcare paint, cause the coating color-changing on upper layer.In existing technology, there are three types of strategies to fix tannic acid altogether: 1)
Using polyvalent metal ion or the carboxylate radical (COO of cationic polymer and tannin-) complexing mode tannin is fixed.But
These can be with the COO of tannin-The cationic substance (polymer of polyvalent metal ion and cation) having an effect is easy to aqueous
Anionic surfactant in resin or water dispersed resin reacts, and consumes partial cation substance, weakens fixation
The function and effect of tannin.But if partial cation compound is diffused into the water-base resin or water dispersed resin on upper layer, easily
Cause bad stability, the film performance deterioration of upper layer coating.So solid using the polymer of polyvalent metal ion and cation
The peaceful method of order has potential danger to upper layer water paint there are promoter effect performance is unstable；2) acid-base neutralization is used
Mode, i.e., using water can be dissolved in, and be directly combined in water in acid tannin in the compound of alkalinity, generate and sink
It forms sediment, it is stripped out and is fixed from water.The mode of this anchoring tannin is the principle according to acid-base neutralization, basic species
It is reacted between matter and tannic acid according to stoichiometric ratio.If alkaline matter additional amount not enough or tannic acid content compared with
More, alkaline matter is depleted, the tannic acid not reacted will be dissolved in water, is diffused on surface and is caused discoloration problem；3)
It is reacted, and is fixed using the carboxyl of ethylenimine derivative and tannin.The ethylenimine derivative of polyfunctionality can be simultaneously
It is reacted with the carboxyl in tannin and water-base resin, generates the polymer network of high crosslink density.Highly cross-linked polymer network
It is acted on by physical barrier, can effectively limit tannin from timber to the diffusion of paint film surface layer.With complexing and acid-base reaction phase
Than the reaction speed of ethylenimine derivatives reaction method is slower, has stayed more time to tannin diffusion；In addition, ethylenimine derivative
Price it is generally higher, if be used alone ethylenimine derivative as tannic acid dispersion inhibitor in use, material cost
It is higher.
Summary of the invention
For overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of aqueous woodware paints of inhibition tannin diffusion
Auxiliary agent and application.
The purpose of the present invention is what is be achieved through the following technical solutions: it is a kind of inhibit tannin diffusion aqueous woodware paint help
Agent, including the following raw material matched in parts by weight:
The modified ethylenimine compound is trimethylolpropane-three [3- (2- methylaziridine base) propionic ester], three hydroxyls
Methylpropane-three (3- '-aziridino propionic ester), pentaerythrite three (3- '-aziridino propionic ester), (the 3- nitrogen third of pentaerythrite four
At least one of piperidinyl propionic ester).
Further, the polyetheramine is polyetheramine D230, polyetheramine D400, polyetheramine D2000, polyetheramine D5000, gathers
At least one of ether amines T403.
Further, the solvent is ethyl alcohol or ethanol-water mixture.It is molten that the present invention selects ethyl alcohol or ethanol water to make
Agent, material source are wide, cheap and easy to get.When being configured to seal coat in this auxiliary agent and water-base resin and being constructed, dehydrated alcohol
Azeotropic mixture can be formed with the water in water-base resin, accelerate paint film dry, reduction tannin is dissolved out from timber and tannin is being closed
Diffusion time in priming paint.In addition, the present invention directly compounds, and without being reacted, operation easy spy simple with equipment
Point.
Further, auxiliary element of the calcium chloride as the aqueous woodware paint auxiliary agent for inhibiting tannin diffusion.
A kind of application of aqueous woodware paint auxiliary agent, the application are as follows: water is made in aqueous woodware paint auxiliary agent and coating additive
Property coating or water-base resin.Aqueous paint additive can inhibit the diffusion of tannin in timber, prevent white or light-colored coating because of tannin
Scattering and permeating and change colour, improve construction efficiency, extend the service life of coating.
The preparation method of the aqueous woodware paint auxiliary agent of above-mentioned inhibition tannin diffusion, comprising the following steps:
(1) under room temperature, by modified ethylenimine compound, solvent, deionized water (the 20% of deionized water gross mass)
It puts into reaction kettle, raw material is uniformly mixed by starting stirring (mixing speed controls within the scope of 60-90 revs/min)；
(2) polyetheramine is slowly added into the mixed solution that step (1) obtains, is stirred evenly；
(3) under room temperature or heating, stirring condition, by calcium chloride be dissolved in remaining deionized water (deionized water gross mass
80%) in, the solution of homogeneous transparent is obtained, is then slowly added into the solution that step (2) obtains and is stirred evenly, is filtered
Packaging.
The beneficial effects of the present invention are: the present invention passes through three kinds of acid-base neutralization, complexing and chemical reaction effects
Mode, collaboration inhibit tannic acid in timber to spread to upper layer paint film.The neutralization reaction of alkaline matter and tannic acid, this reacts anti-
Answer speed very fast, polyetheramine quickly can fix tannin with tannic acid according to stoichiometric reaction in the short time；In addition,
Complexing between calcium ion and tannic acid carboxyl is also fast reaction, and with two carboxylate radicals network can occur for a calcium ion
Cooperation is formed with octatomic ring chelate is generated using calcium ion as network structure (expansion of this network structure to tannic acid of crosslinking points
It dissipates and forms certain resistance)；Ethylenimine derivative is slow irreversible reaction with reacting for tannin carboxyl, is thus generated
High density cross-linked network can effectively limit the diffusion of free tannic acid.Three kinds of acid-base neutralization, complexing and chemical reaction
The mode of action matches, polyetheramine-tannin (acid-base neutralization) and calcium ion-tannin (complexing), quickly by big portion therein
Divide tannin anchoring；Ethylenimine-the tannin and ethylenimine-water-base resin of long response time generate high cross-linked network by chemical reaction,
The diffusion of tannin is further limited, thoroughly by tannic acid barrier below primary coat.
