Embodiment 1
[0034] It includes the following steps: step one, preparation of furfuryl alcohol resin; step two, degreasing; step three, washing and drying; step four, cross-linking treatment; step five, acetylation and cyanoacetation treatment; step six, resin impregnation treatment; step seven , Wood bleaching and dyeing;
[0035] Among them, in the above step 1, according to the weight percentage of each raw material, they are: furfuryl alcohol 55%, formaldehyde 15%, urea 10%, sodium hydroxide 5%, acetic acid 5%, p-toluenesulfonic acid 5%, xylene sulfonic acid 5% is selected and weighed according to the above weight; first add formaldehyde to the reactor, add urea under stirring, and add 1 / 4 of the total furfuryl alcohol, turn on steam to heat, and add sodium hydroxide solution to adjust the pH value , Continue to heat up to about 98°C. At this time, you can see that there is reflux, that is, the reaction product is produced, from the sight of the reflux. The time is 15 minutes after seeing...
