Problems solved by technology

[0004] In the prior art, wood products made of oak are prone to mildew and corrosion during use. Therefore, the surface needs to be treated for protection and to improve its service life. Usually, paint is used to do so. However, paint is applied directly on the surface of oak products, but the adhesion is poor, resulting in a significant reduction in the service life of the coating

Abstract

The invention discloses a method for improving surface coating performance by treating rubber wood based on a steam explosion method, and relates to the technical field of wood product treatment. Themethod comprises the steps that oak is subjected to alkali liquor treatment, and steam explosion treatment is conducted after alkali liquor treatment, wherein the alkali liquor treatment is carried out under a microwave-assisted condition, the alkali liquor is obtained by mixing a strong alkali solution and a weak alkali solution, and the mixing mass ratio of the strong alkali solution to the weakalkali solution is 3: (1-1.5); the oak surface treated through the method has better brushing performance, the binding force between the oak surface and a coating can be greatly improved, and therefore the oak surface can be used for a longer time, and the situation that the coating on the surface falls off too early is avoided.

Description

Technical field [0001] The invention belongs to the technical field of wood products, in particular to a method for improving the surface coating performance of rubber wood based on a steam explosion method. Background technique [0002] White oak and red oak are collectively referred to as oak, which is hard and heavy and has beautiful patterns. They are high-quality materials for making furniture, floors, and interior wood lines. The oak imported from abroad is divided into two types of commercial materials: white oak and red oak, namely white oak and red oak. Red oak is mainly produced in North America and Europe; white oak is mainly produced in Asia, Europe and North America. The wood structure of red oak and white oak is similar to that of Sawtooth oak and Quercus oak produced in China. [0003] The sapwood and heartwood of oak are slightly distinguished. The sapwood is grayish-yellow-white, and the color of the heartwood is variable, ranging from yellowish brown to reddish ...
