Treatment method for improving adhesive force of wood surface to paint film

Abstract

The invention provides a new method combining temperature-programmed heat treatment and plasma jet treatment to conduct surface treatment on wood, and solves the problem of reduction, caused by a traditional heat treatment method, of adhesive force of a wood surface to a paint film. After adopting the method for carrying out surface treatment on the wood, the adhesive force of the wood surface to the paint film is greatly enhanced. Furthermore, the treatment method will not destroy the interior structure of the wood, is easy to operate and can be popularized and applied serving as a good wood treatment method.

Description

technical field [0001] The invention relates to a surface treatment method in the field of chemical materials, in particular to a treatment method for improving the adhesion of a wood surface, especially larch wood, to a paint film. Background technique [0002] my country's relatively low-quality artificial forests, especially larch wood, are rich in wood, heavy and solid in texture, strong in compression and bending, and good in corrosion resistance. They are used for poles, sleepers, bridges, mine pillars, vehicles, It is an excellent material for construction, etc., but its stability and color problems have always been the disadvantages of its application. Wood high-temperature heat treatment is a commonly used wood modification method. The process is simple and the treatment process has no pollution to the environment. It can improve the quality of wood, reduce the hygroscopicity and water absorption of wood, and improve dimensional stability, biological corrosion resist...

Problems solved by technology

[0002] my country's relatively low-quality artificial forests, especially larch wood, are rich in wood, heavy and solid in texture, strong in compression and bending, and good in corrosion resistance. They are used for poles, sleepers, bridges, mine pillars, vehicles, It is an excellent material for construction, etc., but its stability and color problems have always been the disadvantages of its application.

[0003] However, after the wood is improved by the current high-temperature heat treatment technology, its surface finishing performance, bonding performance, especially the adhesion of the wood surface to the paint film are all reduced, which directly affects the functional improvement and decorative properties of wood products.
