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...

Abstract

The invention discloses furfuryl alcohol resin wood and a modification treatment process. The furfuryl alcohol resin wood comprises a wood body, a sliding block, a sliding groove, positioning holes, threaded holes, concave grooves, fixing bolts, a polyvinyl chloride coating, a wear-resistant layer, a wood grain layer, an anti-corrosion layer, a balance layer, through holes, a mounting groove, a spring and a ball, wherein the sliding block is installed on one side of the wood body, the positioning holes are formed in the two ends of the outer side of the sliding block correspondingly, the threaded holes are formed in the two sides of the top end of the sliding block correspondingly, the sliding groove is formed in one side of the wood body, and the concave grooves are formed in the two endsof the top end of the sliding groove correspondingly; and the through holes are formed in the centers of the interiors of the concave grooves, the fixing bolts are arranged inside the through holes,and the fixing bolts are connected with the threaded holes in a matched mode; according to the wood and the process, the treatment process comprises the following steps of preparing the furfuryl alcohol resin; degreasing; cleaning and drying; cross-linking treatment; acetylation and cyanation treatment; resin impregnation treatment; wood bleaching and dyeing, so that the wear resistance and the corrosion resistance of the furfuryl alcohol resin wood are effectively ensured.

Description

technical field [0001] The invention relates to the technical field of wood modification, in particular to a furfuryl alcohol resin wood and a modification treatment process. Background technique [0002] Physical or (and) chemical processing methods to improve or change the physical, mechanical, chemical properties and structural characteristics of wood, the purpose of which is to improve the natural decay resistance (moth) resistance, acid resistance, alkali resistance, flame retardancy, Abrasion resistance, color stability, mechanical strength and dimensional stability, the modified wood is called modified wood or improved wood. As for the protective treated wood, plywood, particle board, etc., although they have some properties of modified wood, But it is customary not to be included in the category of modified wood. [0003] However, the existing wood does not have good acid resistance, alkali resistance, flame retardancy, abrasion resistance, color stability, mechanic...
