Further, asked to verify the water solubility of flavonol in the water-based white primer solution bamboo and wood for bamboo wooden articles
The effect of topic, can be with embodiment 1, the corresponding water-based white primer for bamboo wooden articles of embodiment 2 as laboratory sample, and city
It is control sample to sell product 1 (cation-type water-thinned white seal coat), commercially available prod 2 (anion-type water-thinned white seal coat)
Product, the contrast experiment for close flavones pigment, concrete operations can be as follows：
With 20cm × 15cm bamboo and woods as testing substrates, gently polish off the burr of testing substrates with 400# sand paper and clear up dry
After net, in the testing sample of the surface spraying 4.0g of testing substrates, testing substrates are then dried 24 hours at 25 DEG C, then
Continue the aqueous matte white finishes of ZW51467 (production of Foochow Zhan Chen Chemical Co., Ltd.s) in its surface spraying 4g, dry 24 small
When after directly observation coating surface whether there is xanthein and ooze out, then testing substrates can be put into 50 DEG C of oven cooking cycles 7 days, and
Testing substrates are taken out after 7 days, and the direct observation coating surface of base material cooling to be tested whether there is color to ooze out, and contrasts color change
Degree.
After being tested with above-mentioned method of testing, test result can be specifically as shown in table 2, wherein, numeral 0 to 5 represents paint
Film discoloration, 0 represents that the paint film of testing substrates represents that the paint film of testing substrates is light discolouration, 2 expressions without any discoloration, 1
The paint film of testing substrates is general discoloration, 3 represents that the paint film of testing substrates is moderate discoloration, and the paint film of 4 expression testing substrates is
Severe discoloration, the paint film of 5 expression testing substrates are serious discoloration.
