| titleOfInvention | Method for treatment of lignocellulose materials, in particular, wood and material prepared by this method |
| abstract | FIELD: wood materials. n SUBSTANCE: invention relates to a method for protection of wood providing to confer its hydrophobic properties for enhancing its longevity and stability of sizes. Invention describes a method for chemical treatment of lignocellulose materials, in particular, a wood lump. Indicated material is impregnated with a chemical agent containing hydrocarbon chains and this agent is chosen from mixed anhydrides containing the first hydrocarbon chain R and the second hydrocarbon chain R 1 wherein R or R 1 represents (C 2 -C 4 )-carboxylic acid, and R 1 and R represents saturated or unsaturated (C 6 -C 24 )-fatty acid with exception mixed anhydride of acetic/benzoic acid. Indicated agent is useful for carrying out grafting based on a covalent bond in a great number of hydrocarbon chains with indicated materials. Grafting is carried out by the esterification reaction of indicated lignocellulose materials using a chemical agent chosen from organic anhydrides. Impregnation is carried out in the presence of a basic, neutral or weak acid catalyst and in the absence of catalyst also by immersion and irrigation in autoclave. Treatment is carried out at temperature from room value to 150°C but preferably from 100°C to 140°C. Also, invention describes an article based on lignocellulose fibers material, in particular, wood lump prepared by above described method. Proposed method provides preparing lignocellulose material, in particular, a wood lump with uniform fibers and smooth shape showing the absorption coefficient 3.5% and the swelling coefficient 3.5%. n EFFECT: improved method of treatment. n 16 cl, 3 dwg, 3 tbl, 2 ex |
