Method for improving mechanical stability of super-hydrophobic wood

Abstract

The invention discloses a method for improving the mechanical stability of super-hydrophobic wood, belonging to the field of super-hydrophobic wood. The super-hydrophobic wood prepared by adopting the method disclosed by the invention overcomes the defects of poor surface mechanical property, short service life and the like of the super-hydrophobic wood prepared by adopting a conventional method, and is improved in durability and good in application prospect. A contact angle between the super-hydrophobic wood and water is more than 150 DEG, and a rolling angle is less than 10 DEG, therefore, the super-hydrophobic wood has excellent hydrophobic property and better self-cleaning property. The method comprises the following steps: soaking wood in epoxy resin to ensure that one layer of epoxy resin is covered on the surface of the wood; then soaking in a silicon dioxide solution grafted with an amino group to ensure that silicon dioxide reacts with epoxy resin so that the silicon dioxide is adhered on the surface of the epoxy resin to form a micro-nano secondary structure; and finally, carrying out hydrophobic modification on the micro-nano secondary structure on the surface of the wood, therefore the super-hydrophobic wood is prepared. The method is used for improving the mechanical stability of the super-hydrophobic wood.

Description

technical field [0001] The invention belongs to the field of superhydrophobic wood; in particular, it relates to a method for improving the mechanical stability of superhydrophobic wood. Background technique [0002] As a traditional material, wood has a wide range of applications in construction, furniture, etc., and plays a great supporting role in human life. Because traditional wood is exposed to water for a long time or placed in a high humidity environment for a long time, it is prone to corrosion, mildew and other phenomena, which greatly reduces the service life of wood and affects the efficiency of wood use. Therefore, the invention of hydrophobic wood has become an urgent need in the field of wood research. Superhydrophobic wood, because the static contact angle of water on its surface is greater than 150°, and the rolling angle is less than 10°, it has good hydrophobic properties, which makes the wood perform well in anti-corrosion, self-cleaning, and prolonging ...

AI Technical Summary

Problems solved by technology

Existing hydrophobic wood preparation techniques, such as utilizing beeswax to process wood, utilizing the surface of wood to generate nano-inorganic particles, etc. generally have defects such as poor mechanical properties of hydrophobic surface (surface mechanical stability and durability are not good), and short service life. Improving the durability of hydrophobic wood has become another important topic in this research field
