Abstract

The invention discloses an ampelopsis grossedentata extractive natural bamboo wood antiseptic agent and a preparation method thereof. The bamboo wood antiseptic agent is prepared from the following raw materials in percentage by weight: 2.5%-10% of ampelopsis grossedentata extractive, 30%-50% of ethyl alcohol and the balance of distilled water, and the sum of the mass percents of the raw materials is 100%. The preparation method of the bamboo wood antiseptic agent comprises the following steps: mixing the ethyl alcohol and the distilled water at a certain mass ratio so as to form an 30%-50% ethyl alcohol water solution; adding the ampelopsis grossedentata extractive, wherein the mass of the ampelopsis grossedentata extractive and the total mass of the ethyl alcohol and the distilled water is (0.25-1) to 10; stirring in a vacuum reduced-pressure sealing tank body at a temperature 20-60DEG C for 20-60 minutes, and cooling to the normal temperature so as to obtain a bamboo wood antiseptic agent solution containing the ampelopsis grossedentata extractive. The ampelopsis grossedentata extractive natural bamboo wood antiseptic agent provided by the invention has antibiosis and insect preventing effects and a good inhibiting effect for a bamboo wood fungus brown rot fungus (Gloeophyllum trabeum) and white rot fungus (coriolus versicolor), the ampelopsis grossedentata extractive natural bamboo wood antiseptic agent is a full environment-friendly material, the preparation technology is simple, the energy consumption is saved, and compared with chemical antiseptic agents, and the ampelopsis grossedentata extractive natural bamboo wood antiseptic agent has good environment safety.

Description

technical field [0001] The present invention relates to a bamboo preservative and its preparation, in particular to a bamboo preservative containing the extract of S. dentata grape 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 th...
