Abstract

The invention provides a hydrophobic modifier for wood and bamboo wood. The hydrophobic modifier for the wood and bamboo wood contains the following components according to percentage by mass: 0.01 to0.5% of dye, 5 to 15% of organic silicon, 1 to 10% of acid, 40 to 65% of organic alcohol, 20 to 40% of inorganic nanoparticles and 5 to 10 % of water. When the hydrophobic modifier for the wood and bamboo wood is used, all the components of the modifier are ultrasonically stirred for 2 to 5 minutes, then the modifier is applied to the wood or the bamboo wood, and is dried at the temperature of 90-110 DEG C for 1-3 hours. The modifier can solve the problem of poor leaching resistance of wood dyeing and can improve the hydrophobic property of the wood and bamboo wood.

Description

technical field [0001] The invention belongs to the field of wood dyeing, and in particular relates to a wood and bamboo hydrophobic modifier and application thereof. Background technique [0002] Wood has high specific strength, is easy to process, has natural three-dimensional dynamic texture, can adjust humidity and temperature, and is an excellent building and decoration material. In addition, wood is renewable compared to rubber, plastic and stone. Therefore, the development of wood processing and application is in line with the requirements of green development. However, as one of the four major renewable materials, wood has a single color, which makes it difficult to meet the diverse market needs. At present, by staining wood, it is possible to achieve a variety of wood colors. However, the wood loss resistance is relatively poor after dyeing with water-based dyes. In addition, wood is a hydrophilic substance, which is easy to absorb water and moisture during use,...
