Problems solved by technology

However, the color obtained by using only copper sulfate is relatively light, which is difficult to meet the requirements
Zhang Shangzhen treated the bamboo with methanol or ethanol solution of copper salt, the treated bamboo was green, and the effect of using methanol as a solvent was better than that of ethanol, but no further description was made on the stability of the color
And this method is toxic to the human body due to the use of methanol

Abstract

The invention discloses a preparation method and a use method of a bamboo green-keeping agent. The bamboo green-keeping agent comprises two treating agents, namely a treating agent A and a treating agent B; the treating agent A is mainly formed by compounding chitosan, a copper salt and an acid; and the treating agent B is mainly formed by compounding a copper salt with ammonia water or organic amine. Bamboo treated with the green-keeping agent is dark green in bamboo green, can keep green, and has obvious gloss and light resistance, and the green-keeping agent has the advantages of improvement of the color durability of the treated material, simple treatment method, non-toxicity, and no pungent smell of the treated material.

Description

technical field [0001] The invention relates to a preparation and method of a bamboo green-preserving agent, which aims to keep green bamboo green for a long time and prevent green bamboo from fading due to the influence of light, biology and the like. Background technique [0002] Bamboo is a biomass resource widely distributed in China. Bamboo as a raw material can be used in bamboo construction, bamboo handicrafts, bamboo decorations, bamboo wood-based panels and composite materials, etc., and has a wide range of applications. The green color of bamboo on the surface of freshly felled bamboo is green to dark green, bright in color, and has high aesthetic appreciation value. However, with the prolongation of the use time, the bamboo green color on the surface of bamboo gradually changes from green or dark green to gray or yellow, and the color gradually becomes dim. If the natural green of bamboo can be maintained through certain technical treatment, and it will not fade...
