Wood surface hydrophobic insect-resistant treatment method

Abstract

The invention discloses a wood surface hydrophobic insect-resistant treatment method. A painting solution is firstly prepared, wood is treated under the environment at the temperature being 65 DEG C and the air relative humidity being 60%, the wood is put into soaking liquid to be soaked, the wood surface is painted with the painting solution, and then drying is carried out. The wood surface hydrophobic insect-resistant treatment method is easy to operate and easy to implement, the method solves the problems that a super-hydrophobic wood film layer prepared through an existing method is poor in mechanical stability and short in service life, and the good mechanical stability and the good durability are achieved. After wood surface treatment, the contact angle ranges from 156 degrees to 158 degrees, the rolling angle is smaller than 5 degrees, the super-hydrophobic performance is achieved, and the method is green and environment-friendly. The wood prepared through the method can be applied to occasions of decoration in a bathroom, landscape architecture buildings, wooden palisades, balcony floors and the like due to the good hydrophobic property, the good self-cleaning property, the good anti-fouling property and the like, and the market prospect is wide.

Description

technical field [0001] The invention relates to the field of wood treatment, in particular to a treatment method for hydrophobic and insect-proof wood surfaces. Background technique [0002] Wood is a renewable, recyclable and naturally degradable green material and biological resource. It has the advantages of beautiful texture, natural color, comfortable texture, good plasticity, and easy processing. However, wood also has some defects, such as dry shrinkage and wet swelling due to changes in moisture content, resulting in changes in the size and shape of components and reduction in strength, easy to mildew and decay, easy to be eaten by insects, easy to burn, etc. At present, the anti-corrosion treatment of wood mainly relies on the coating of waterproof and anti-corrosion paint on the wood surface, but the adhesion between the paint layer and the wood surface is poor, easy to fall off, and the effect is still unsatisfactory. At present, most of the wood hydrophobic modif...

Problems solved by technology

At present, the anti-corrosion treatment of wood mainly relies on the coating of waterproof and anti-corrosion paint on the wood surface, but the adhesion between the paint layer and the wood surface is poor, easy to fall off, and the effect is still unsatisfactory. At present, most of the wood hydrophobic modification materials are chemically synthesized, which has a certain degree of toxicity. Or the environmental pollution of raw material preparation, some have complex processes, and some have high costs, all of which have different degrees of limitations
