Bamboo wood preservative made from natural plant source and preparation method thereof

Abstract

The invention discloses a bamboo wood preservative made from a natural plant source and a preparation method of the bamboo wood preservative. The bamboo wood preservative comprises, by mass, 2.5%-10% of extract from roots of kudzu vines, 1%-5% of extract from smoke trees, 1%-5% of extract from onions, 30%- 60% of alcohol and the balance distilled water, wherein the sum of the mass percentages of the materials is 100%. The preparation method of the bamboo wood preservative comprises the steps that alcohol and distilled water are mixed according to a mass ratio into ethanol water with the mass percentage of 30%-60%, the extract from roots of kudzu vines, the extract from smoke trees and the extract from onions are added into the ethanol water according to the mass percentages, the mixture is stirred for 30 minutes to 60 minutes in a vacuum decompression sealed tank at the temperature of 50 DEG C to 60 DEG C, the mixture is cooled to the normal temperature, and then a bamboo wood preservative solution containing the extract from roots of kudzu vines, the extract from smoke trees and the extract from onions is obtained, wherein the mass percentage of the extract from roots of kudzu vines, the mass percentage of the extract from smoke trees and the mass percentage of the extract from onions are certain. The bamboo wood preservative made from the natural plant source has the antibacterial function and the insect prevention function and can well restrain bamboo wood rotting fungi, brown rot fungi (Gloeophyllum) and white rot fungi (Coriolus versicolor). The bamboo wood preservative is a totally environmentally friendly material, the preparation technology is simple, energy consumption can be reduced, and compared with a chemical preservative, the bamboo wood preservative is high in safety for the environment.

Description

technical field [0001] The invention relates to a bamboo preservative and its preparation, in particular to a natural plant source bamboo preservative and its preparation method. Background technique [0002] The protection methods of bamboo and bamboo products are mainly divided into two categories: one is physical method, such as infrared heating method, steaming method, baking method, microwave method, ultrasonic method, etc.; the other is chemical method, which uses chemical agents to effectively It can effectively kill the existing pests and infected wood rot fungi in the bamboo, and it can also protect the bamboo from being eroded by fungi. The main advantages of the physical method are low toxicity and less environmental pollution, but the effect of killing insects is poor; the chemical method is the most commonly used method to prevent bamboo decay, and the antiseptic effect of chemical agents is good, the validity period is long, and the physical and chemical proper...

AI Technical Summary

Problems solved by technology

The main advantages of the physical method are low toxicity and less environmental pollution, but the effect of killing insects is poor; the chemical method is the most commonly used method to prevent bamboo decay, and the antiseptic effect of chemical agents is good, the validity period is long, and the physical and chemical properties of bamboo are not damaged. The disadvantage is the leakage and seepage of preservatives during production and use, chemicals are prone to toxicity and adverse effects on the environment, and endanger human health
