Biomass coloring agent used for coloring xylosma white edge material and preparation method thereof

Abstract

The invention provides a biomass coloring agent used for coloring a xylosma white edge material and a preparation method thereof, relates to a bioass coloring agent and a preparation method thereof, and aims at solving the problems that the conventional method of directly removing the white edge leads to the waste of resource during removal of the xylosma white edge, the conventional coloring agent causes heavy pollution, and the conventional method for preparing the coloring agent is complex in process and cannot realize green and environmental protection purposes. The biomass coloring agent used for coloring the xylosma white edge material is prepared from xylosma powder and ammonia water in massic volume proportion. The preparation method comprises the following steps of: mixing the ammonia water with the xylosma powder; standing for 1 to 2 days at room temperature in a sealing manner to obtain a mixture; and filtering the mixture to obtain a filtrate which is the biomass coloring agent used for coloring the xylosma white edge. After the xylosma white edge is colored through the prepared biomass coloring agent, the ageing resistance of the xylosma edge material is close to that of a heartwood, so that the color difference between the xylosma edge and the core material is reduced, and the color is towards the unification. The method is simple in operation, green and environment-friendly, and is applied to the xylosma coloring field.

Description

technical field [0001] The invention relates to a biomass dyeing agent and a preparation method thereof. Background technique [0002] Oak wood is tough, with exquisite patterns and colors, and has a wide range of uses. It is a commonly used wood for floor and furniture decoration. Its sapwood is light yellow, with brown inside, commonly known as "white skin" or "white edge" in factories; the heartwood is dark brown. Because the color difference of the sapwood of oak wood is obvious, it has seriously affected the commercial value and utilization value of oak wood. In order to meet people's needs and improve the decorative performance and aesthetic value of oak wood, it is very necessary to eliminate the white edge of wood. When cutting materials, some manufacturers use the direct removal method to eliminate white edges, but this is a waste of resources; With the improvement of production and application of synthetic dyes, people are paying more and more attention to the p...
