Problems solved by technology

1) Physical methods: mainly include high temperature method, water immersion method, smoke method, modified atmosphere method, far infrared method, microwave method, ray method, etc. Although these methods are harmless and non-toxic, the treated bamboo or bamboo products, If it is not kept properly, it will be re-infected with moths and molds, etc.
2) Chemical methods: mainly coating method, impregnation method, cooking method, fumigation method, pressurized injection method, etc. Although these methods have better effects on moth prevention and anticorrosion, but the agents are generally poisonous and easy to cause pollution to products and the environment

Embodiment 1

[0014] Remove bamboo green and bamboo yellow from fresh bamboo; dip into ionic liquid bromide 1-butyl-3-methylimidazolium [Bmim]Br, and raise the temperature to 50°C, after leaching for 3 hours, take out the bamboo and Immersion into [Bmim]Br / TiCl 4 In the mixed solution, after soaking for 0.5h, slowly add a certain amount of distilled water, raise the temperature of the mixed solution to 100°C, and slowly add concentrated ammonia water dropwise to adjust the pH value of the mixed solution to 7, and react for 30 minutes, take out the bamboo, and use Rinse the sediment on the surface, put it into a blast drying box for drying, and wait for cooling to obtain the self-cleaning functional bamboo.

Embodiment 2

[0016] Remove bamboo green and bamboo yellow from fresh bamboo; dip into ionic liquid bromide 1-octyl-3-methylimidazolium [Omim]Br, and raise the temperature to 90°C, after leaching for 1 hour, take out the bamboo and Immersion into [Omim]Br / TiCl 4 In the mixed solution, after soaking for 2 hours, slowly add a certain amount of distilled water, raise the temperature of the mixed solution to 100°C, and slowly add concentrated ammonia water dropwise to adjust the pH value of the mixed solution to 9, and react for 30 minutes. The sediment on the surface is put into a blast drying box for drying, and after cooling, the self-cleaning functional bamboo is obtained.

Embodiment 3

[0018] Remove bamboo green and bamboo yellow from fresh bamboo; dip into ionic liquid 1-butyl-3-methylimidazolium chloride [Bmim]Cl, and raise the temperature to 80°C, after leaching for 2 hours, take out the bamboo and Immersion into [Bmim]Cl / TiCl 4 In the mixed solution, after soaking for 1 hour, slowly add a certain amount of distilled water, raise the temperature of the mixed solution to 100°C, and slowly add concentrated ammonia water dropwise to adjust the pH value of the mixed solution to 8, and react for 30 minutes. The sediment on the surface is put into a blast drying box for drying, and after cooling, the self-cleaning functional bamboo is obtained.

Abstract

The invention discloses a self-cleaning functional bamboo and a preparation method thereof. TiCl4, ionic liquid, etc. are used as main raw materials, and the titanium dioxide-loaded bamboo with self-cleaning function is prepared by leaching / in-situ hydrolysis technology. The invention not only improves the properties of the bamboo material such as mildew resistance, moth resistance, corrosion resistance, wear resistance, weather resistance, etc., but also has self-cleaning functions such as antibacterial, sterilizing, and air purification. The invention solves the problems of uneven loading and easy falling off of the loaded titanium dioxide bamboo material prepared by the traditional method. The success of this technology has important practical significance for alleviating the shortage of timber resources, expanding the application range of bamboo and maintaining sustainable development.

Description

technical field [0001] The invention belongs to the field of bamboo materials, and in particular relates to a self-cleaning functional bamboo material and a preparation method thereof. Background technique [0002] Because bamboo grows fast, yields high, matures early, and bamboo has high strength, good toughness, and high hardness. Its main mechanical properties are comparable to those of hard broad-leaved trees. It has broad development and application prospects as an engineering structural material. Therefore, it is known as the second forest resource and is an important substitute material for wood. However, because bamboo contains more nutrients than ordinary wood, it is easy to rot, mildew, insects and easy to burn under warm and humid conditions, which greatly limits the application range of bamboo products. Therefore, how to expand the use range of bamboo and improve the added value and utilization of bamboo through the improvement of bamboo properties has become an...
