Problems solved by technology

[0002] As an ancient and young green and environmentally friendly material, wood is widely used in daily life, such as wooden houses, wooden boats, wood carvings, tables and chairs, etc. Wood is mainly composed of cellulose, hemicellulose, lignin, etc., cellulose 1. Hemicellulose is rich in groups such as hydroxyl groups with strong hygroscopicity, so wood has strong water absorption, which can easily lead to problems such as rot, insects, deformation, and poor dimensional stability.

Abstract

The invention discloses a wood surface hydrophobic treatment method and relates to the technical field of wood treatment. The wood surface hydrophobic treatment method comprises the following steps: (1) pre-treatment; (2) microwave treatment; (3) vacuum impregnation; (4) low-temperature plasma treatment; when wood is treated through the wood surface hydrophobic treatment method disclosed by the invention, not only can the hydrophobic properties of wood surfaces be effectively improved, but also the corrosion resistance of the wood surfaces can be effectively improved, so that the application range and the working life of the wood can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of wood treatment, and in particular relates to a wood surface hydrophobic treatment method. Background technique [0002] As an ancient and young green and environmentally friendly material, wood is widely used in daily life, such as wooden houses, wooden boats, wood carvings, tables and chairs, etc. Wood is mainly composed of cellulose, hemicellulose, lignin, etc., cellulose 1. Hemicellulose is rich in groups such as hydroxyl groups with strong hygroscopicity, so wood has strong water absorption, which can easily lead to problems such as perishability, insects, deformation, and poor dimensional stability. These properties of wood make the service life of wood restricted by many environmental factors, such as humid air, acid rain, etc. Hydrophobic treatment of wood surface, endowing wood surface with waterproof function, can effectively broaden the application range of wood in production and life, and prol...
