Embodiment 4

[0025] Embodiment 4 (contrast the corresponding raw material and weight ratio value of embodiment 4 in Table 1):

[0026] First, dissolve 2.5 parts of boric acid and 2.5 parts of borax in 100.0 parts of water, stir to dissolve them completely, then add 30.0 parts of polyethylene glycol, stir well, then add 1.5 parts of acid dye, and stir again until completely dissolved, that is, the protection main agent. The 2-meter-long fresh raw bamboo (or log) is directly soaked in the protective main agent prepared according to the method of Example 4 for 10 days without opening the bamboo joints. Take it out and place it in the molten hydrophobic agent solution, gradually raise the temperature to 80°C at 5°C per hour, keep warm for 30 minutes at every 5°C rise, and then heat at 2°C per hour to 105°C, keep at 60°C at every 2°C rise In minutes, the antibacterial, anti-insect and anti-crack treatment of raw bamboo (log) is completed.

[0027] All the other examples 1, 2, 3 and 5-8 are co...

Abstract

The invention discloses a log and raw bamboo protective agent. The log and raw bamboo protective agent comprises a main protective agent body and a hydrophobic agent and is characterized in that the main protective agent body is composed of, by weight, 1.0-10.0 parts of fungicide and insecticide, 10-30.0 parts of water-soluble monomers and / or polymer, 0.0-5.0 parts of coloring agents and 100.0 parts of water; and the hydrophobic agent is composed of, by weight, 90.0-98.0 parts of paraffin and 2.0-10.0 parts of auxiliaries. According to application of the protective agent, the bottom of a log or the bottom of raw bamboo is erected in a tank containing the main protective agent or transversely immersed into the tank containing the main protective agent, or vacuum pressure treatment is adopted; then the log or the raw bamboo is subjected to hydrophobic drying treatment, and the log or the raw bamboo is cooled and discharged. The treated log and the raw bamboo are low in moisture content, quite remarkable in fungus, insect and cracking resistant effect, good in medicine leachability resistance, long in validity period, capable of conducting drying and coloring treatment and good in energy-saving effect.

Description

technical field [0001] The invention relates to a wood and bamboo chemical antibacterial, anti-insect and anti-crack protective agent and its application method. Background technique [0002] my country is very rich in bamboo resources. Bamboo grows fast and has a short cycle, and bamboo is the closest to wood in terms of shape and properties. It is widely used in papermaking, construction, furniture and wood-based panels, and is an important substitute for wood. The growth cycle of wood is relatively long, the effect of water and soil conservation is great, and the effect of ecological protection is remarkable. The logging is strictly controlled, and the utilization of wood resources is subject to certain restrictions. [0003] Bamboo poles and tree poles that have not been split and processed after felling maintain the organizational structure and morphological characteristics of raw bamboo and logs, have the mechanical strength and aesthetic effect of raw bamboo logs, an...
