Abstract

The invention relates to wooden floor white edge sap stain and a preparation method thereof. Bar is cut into a block with the length ranging from 40 mm to 150 mm and the width ranging from 20 mm to 40 mm; the curtal bark is immersed in an alkaline solution with the pH value not smaller than 8.5 for 4-12 hours under the conditions of the normal temperature and shading, stirring is regularly carried out for 1-3 times in the immersing process, and the mass ratio of the bar to the alkaline solution ranges from 1 Kg: 5Kg to 1 Kg: 10 Kg; and the soak solution is filtered, the obtained filtrate is the wooden floor white edge sap stain. According to the wooden floor white edge sap stain and the preparation method therefore, the bar abandoned during wood processing serves as a raw material, the pigment in the bark is extracted through alkaline solution immersing, the leach liquor is smeared to the white edge, equivalently, the white edge is colored, the pigment of the leach liquor is extracted from the bar for making the floor material, and the color of the colored white edge and the color of a core material are basically consistent.

Description

technical field [0001] The invention relates to a biomass dyeing agent and a preparation method thereof. Background technique [0002] Among the woods commonly used in floor and furniture decoration, the core material and sapwood of most woods are different in color, especially the core material of a large amount of oak used for flooring is gray-black, while the sapwood is white, commonly known as "white bark" in factories. " or " white edge ", if the floor blank or surface board processed by it is not repaired, there will be serious color difference, which is unacceptable to most consumers. [0003] In the past, the usual method of repairing white edges was to purchase a special white edge repair agent, which is not only expensive, but also has an unsatisfactory dyeing effect. In addition, the purchased white edge repair agent contains a large amount of volatile toxic and harmful substances, such as formaldehyde, benzene, heavy metals, etc. , Harmful to the environment, hu...
