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

[0012] (1) Remove the bamboo green and bamboo yellow from the bamboo, and dry it in an oven at 103°C for 24 hours.

[0013] (2) Take 5g of trichloroazine (C 3 N 3 C1 3 ) and 3g of ammonium chloride (NH 4 C1) put into the autoclave, then add 200 ml of benzene, after stirring for 30min, place the bamboo of step 1) in the autoclave, feed nitrogen into the autoclave to fully drive away the air in the autoclave system, and Apply a pressure of 30MPa to the reactor, then raise the temperature in the reactor to 300°C at a rate of 1°C / min, and react at constant temperature and pressure for 3 hours. After naturally cooling to room temperature, take out the bamboo and The product was washed with hydrochloric acid and acetone, and then the bamboo was repeatedly washed with distilled water until the cleaning solution was neutral, and then dried in an oven at 103°C to obtain a functional bamboo with graphite phase carbon nitride.

Embodiment 2

[0015] (1) Remove the bamboo green and bamboo yellow from the bamboo, and dry it in an oven at 103°C for 24 hours.

[0016] (2) Take 8 g of trichloroazine (C 3 N 3 C1 3 ) and 4g of ammonium chloride (NH 4 C1) put into the autoclave, then add the benzene of 300 ml, after stirring for 30min, place the bamboo of step 1) in the autoclave, feed nitrogen into the autoclave to fully drive away the air in the autoclave system, and Apply a pressure of 35MPa to the reactor, then raise the temperature in the reactor to 250°C at a rate of 2°C / min, and react at constant temperature and pressure for 2 hours. After cooling down to room temperature naturally, take out the bamboo, and The product was washed with hydrochloric acid and acetone, and then the bamboo was repeatedly washed with distilled water until the cleaning solution was neutral, and then dried in an oven at 103°C to obtain a functional bamboo with graphite phase carbon nitride.

Embodiment 3

[0018] (1) Remove the bamboo green and bamboo yellow from the bamboo, and dry it in an oven at 103°C for 24 hours.

[0019] (2) Take 10g of trichlorozine (C 3 N 3 C1 3 ) and 3.5g of ammonium chloride (NH 4 C1) put into the autoclave, then add the benzene of 500 ml, after stirring for 30min, place the bamboo of step 1) in the autoclave, feed nitrogen into the autoclave to fully drive away the air in the autoclave system, and Apply a pressure of 40MPa to the reactor, then raise the temperature in the reactor to 280°C at a rate of 1.5°C / min, and react at constant temperature and pressure for 2.5 hours. After naturally cooling to room temperature, take out the bamboo and Wash the product with hydrochloric acid and acetone in sequence, and then wash the bamboo repeatedly with distilled water until the cleaning solution is neutral, then place it in an oven and dry it at 103°C to obtain a functional bamboo with graphite phase carbon nitride.

Abstract

The invention discloses an immobilized graphite carbon nitride functional-bamboo and a preparation method thereof. C3NC13 and NH4C1 are used as raw materials and are heated and pressed to prepare the immobilized g-C3N4 functional-bamboo under a specific solvent. In the practical application, the bamboo can decompose volatile organic contaminants such as formaldehyde, benzene, methylbenzene and the like very well, has functions of anti-microbial and sterilization, and contaminants attached to the bamboo can be easily removed. Moreover, the performances of resisting mildew, worm eating and decay of natural bamboo are increased to some extent. The success of the technology has an important practical significance on alleviating shortage of wood resources, expanding the range of application of bamboo and maintaining the sustainable development.

Description

technical field [0001] The invention belongs to the field of bamboo materials, and in particular relates to a functional bamboo material immobilized with graphite-phase carbon nitride 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 o...
