Abstract
A kind of claimed method inhibiting woodwork brightness reversion, woodwork is first printed paints again, it wherein prints in ink and adds pH adjusting agent, chelating agent and yellowing inhibition agent, yellowing inhibition agent is added in varnish, pH adjusting agent is added in water-based ink can eliminate a part of tannic acid, chelating agent, which is added, can combine a part of inorganic ions, the reagent for inhibiting brightness reversion is also separately added into ink and varnish, the brightness reversion discoloration of timber can be effectively inhibited, part yellowing inhibition agent is substituted with part weak base and chelating agent, reduce the dosage for inhibiting brightness reversion reagent in water-based ink, it is cost-effective, and reduce influence of the yellowing inhibition agent to ink performance.
Description
Technical field
The present invention relates to a kind of methods inhibiting woodwork brightness reversion.
Background technology
White lacquerware woodwork furniture standing time can change colour long afterwards, turn yellow, main cause is the tannin in timber
Acid can react and change colour with certain metal ions, if tannin is unevenly distributed in timber, can influence coating effect；And resin meeting
Influence the adhesive force of water paint；Wood color unevenness then influences beauty.CN201010202610.1 is changed by being added in coating
Property polyurethane molecular structure and molecular weight and adjust the type of hydrophilic chain extender and dosage and reduce the hydrolysis of polyurethane
Speed obtains the better water paint of yellowing resistance, but its synthesis step is complicated, xanthochromia grade to reduce polyurethane xanthochromia
Also it does not significantly improve；CN201310506797.8 discloses a kind of color inhibition UV woodenware lacquers, by the screening of resin with
And the improvement of photoinitiator, the auxiliary agent for specific function of arranging in pairs or groups improve paint film yellowing resistance and weather resistance.But its effect is paid no attention to
Think, yellowing resistance degree is inadequate.Woodwork brightness reversion problem annoyings always manufacturer.
Invention content
For the present invention for bad to woodwork anti-yellowing property in the prior art, the higher problem of cost has invented one kind
Inhibit the method for woodwork brightness reversion.
The method of the present invention is as follows：Woodwork is first printed paints again, wherein printing ink in addition pH adjusting agent,
Yellowing inhibition agent is added in chelating agent and yellowing inhibition agent in varnish.
The wherein described pH adjusting agent is weak base, preferably ammonium hydroxide, and additive amount is 8-9 to be adjusted to ink pH.
The wherein described chelating agent is selected from EDTA, DTPA, and it is 0.1%-0.5% to be added to weight.
Yellowing inhibition agent is nano-titanium dioxide or nano zine oxide；The addition for the yellowing inhibition agent being added in the ink
Amount is 1%-5% weight, and the additive amount for the yellowing inhibition agent being added in the varnish is 0.5-2% weight.
The additive amount for the yellowing inhibition agent being wherein added in ink is 1-5% weight, the yellowing inhibition agent being added in varnish
Additive amount be 0.5-2%；
Specifically the process for preparation of printing ink is：PH adjusting agent and chelating agent are successively added in colored ink, with
The speed of 300-700r/min stirs 15-45min, adds yellowing inhibition agent, and 10- is stirred with the speed of 300-500r/min
20min obtains ink needed for printing.
Specifically the process for preparation of varnish is：Yellowing inhibition agent is added in varnish the stirring of the speed with 500-800r/min
5-20min obtains required varnish.
The effect that the present invention obtains：
1) a part of tannic acid can be eliminated by weak base (pH adjusting agent) being added in water-based ink, and chelating agent is added can be in conjunction with one
Divide inorganic ions, the reagent for inhibiting brightness reversion is also separately added into ink and varnish, the brightness reversion discoloration of timber can be effectively inhibited.
2) part yellowing inhibition agent is substituted with part weak base and chelating agent, reduces and inhibits brightness reversion reagent in water-based ink
Dosage, it is cost-effective, and reduce influence of the yellowing inhibition agent to ink performance.
Specific implementation mode
Embodiment 1
Configure ink：The DTPA that ammonium hydroxide 10mL and 0.5% weight is added is added in colored ink, with the speed of 500r/min
Degree stirring 20min, adds the nano zine oxide of 1% weight, stirs 10min with the speed of 300r/min, prepares ink；Match
Set varnish：2% weight nano-titanium dioxide is added in varnish, 20min is stirred with the speed of 500r/min, is obtained used
Varnish.Ink is printed onto on timber and is then coated with varnish, obtains the timber of color inhibition.
Embodiment 2
Configure ink：The EDTA that ammonium hydroxide 10mL and 0.1% weight is added is added in colored ink, with the speed of 700r/min
Degree stirring 15min, adds the nano-titanium dioxide of 5% weight, stirs 10min with the speed of 300r/min, prepares ink；
Configure varnish：0.5% weight Nano zinc dioxide impact-resistant is added in varnish, 5min is stirred with the speed of 800r/min, obtains institute
Varnish.Ink is printed onto on timber and is then coated with varnish, obtains the timber of color inhibition.
Comparative example 1
The ink described in embodiment 1 is configured, with common varnish come the varnish in alternate embodiment 1, timber is by printing
After coat varnish.
Comparative example 2
The varnish described in embodiment 2 is configured, is replaced with the ink of pH adjusting agent, chelating agent and yellowing inhibition agent is not added
For the ink in embodiment 2, timber coats varnish after printing.
Comparative example 3
With not adding the ink of pH adjusting agent, chelating agent and yellowing inhibition agent to print wood surface, it is then coated with and is not added with
The varnish of yellowing inhibition agent.According to GB/T 17657-2013《Test methods of evaluating the properties of wood-based panels and surface decorated wood-based panels》, test
Woodwork color fastness to light grade is as a result as follows：
