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...

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 wood’s natural corrosion resistance, acid resistance, alkali resistance, flame retardancy, Abrasion resistance, color stability, mechanical strength and dimensional stability. Wood that has been modified is called modified wood or modified wood. As for wood that has been treated with protection, plywood, particleboard, etc., although they have some properties of modified wood, However, it is customarily not included in the category of modified wood. [0003] However, the existing wood does not have good acid resistance, alkali resistance, flame resistance, abrasion resistance, color stabilit...
