Abstract

The invention discloses a method for constructing a calcium carbonate super-hydrophobic structure on a surface of bamboo wood, and belongs to the technical field of surface modification of bamboo materials and wood materials. The method comprises the following steps that (1), mixed liquid is prepared; (2) the bamboo materials or the wood materials are placed in the mixed liquid obtained in the step (1) to be stirred, the temperature is kept at 5 DEG C to 75 DEG C, and the bamboo materials or the wood materials loaded with the calcium carbonate super-hydrophobic structure are obtained.; and (3), the obtained bamboo materials or wood materials, obtained in the step (2), loaded with the calcium carbonate super-hydrophobic structure are cleaned for 1 time to 5 times through straight-chain saturated aliphatic hydrocarbons, and then are cleaned for 0 time to 5 times through water, the water content is dried to 1% to 29%, and the calcium carbonate bamboo materials or wood materials loaded with the super-hydrophobic structure are obtained. Through calcium carbonate modification, a hydrophobic thin film is constructed on the surface of the bamboo wood, and the surface has the super-hydrophobic effect; and the method is high in stability, achieves the hydrophobic and mould-proof effects, and is simple in production technology and convenient to implement.

Description

technical field [0001] The invention relates to a method for constructing a calcium carbonate superhydrophobic structure on the surface of bamboo wood, and belongs to the technical field of surface modification of bamboo materials and wood materials. Background technique [0002] Bamboo and wood are commonly found in nature and are closely related to people's lives. Daily life cannot be separated from these materials. Bamboo and wood, as a renewable natural resource and environmentally harmonious material, have natural advantages and have very broad development prospects. However, due to the structure and development technology of bamboo and wood, their comprehensive utilization rate is not high. high. Due to the natural defects of bamboo and wood, such as flammability, corrosion, non-hydrophobic, low mechanical strength, etc., the application and use of the products they can produce are limited to a certain extent. When using bamboo and wood, in order to make full use of ...
