Embodiment 1
[0034]The method comprises the following steps: Step 1, furfuryl alcohol resin preparation; Step 2, degreasing; Step 3, washing and drying; Step 4, cross-linking treatment; Step 5, acetylation and cyanoethylation treatment; Step 6, resin impregnation treatment; Step 7 , bleached and stained wood;
[0035] Wherein in above-mentioned step 1, according to the percentage by weight of each raw material is respectively: furfuryl alcohol 55%, formaldehyde 15%, urea 10%, sodium hydroxide 5%, acetic acid 5%, p-toluenesulfonic acid 5%, xylenesulfonic acid 5% is selected, and weighed according to the above weight; first add formaldehyde to the reaction kettle, add urea under stirring, and add 1 / 4 of the total amount of furfuryl alcohol, heat with steam, and add sodium hydroxide solution to adjust the pH value , and continue to heat up to about 98°C. At this time, you can see reflux liquid from the sight glass, that is, the reaction product is produced. Count the time from seeing the refl...
