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
The invention belongs to bamboo wood field, be specifically related to functional bamboo wood of a kind of immobilized graphite-phase carbonitride and preparation method thereof.
Background technology
Because bamboo growth is fast, output is high, become a useful person early, and bamboo wood intensity is high, good toughness, hardness are large, its main mechanical property can compare favourably with Hard―Wood, as structural timber, has wide development prospect.Therefore being described as second forest reserves, is the important substitution material of timber.But because bamboo wood contains more nutriment than general timber, thus under the condition of warm moist, be easy to produce rotten, go mouldy, damage by worms and the feature such as easy firing, greatly limited the range of application of bamboo wood product.Therefore, how by the improvement of Bamboo properties, expand the scope of application of bamboo wood, improve bamboo wood added value and utilization rate and become problem demanding prompt solution.
Current anticorrosion and mothproof two kinds of Physical and chemical methods that are mainly divided into of bamboo wood.1) physical method: mainly contain high temperature method, bowssening, fumigation, controlled atmosphere method, far infrared collimation method, microwave method, ray method etc., although these methods are nuisanceless, without residual hazard; But bamboo wood or bamboo product after processing, if improper storage can infect moth and mould etc. once again.2) chemical method: mainly contain rubbing method, infusion process, cooking process, fumigating system, pressurization injection method etc., although mothproof, the anticorrosion texts of these methods is better; But medicament is generally poisonous, easily to goods and environment.And along with the enhancing of people's environmental consciousness, more and more higher to the environmental requirement of the insect-proof agent of bamboo wood, anticorrisive agent, mould inhibitor and standard, as most countries such as the U.S., Japan, Europe, banned use of the anticorrisive agents such as CCA, PCP.Therefore develop the focus that a kind of eco-friendly bamboo wood improved process becomes current research.
Summary of the invention
The object of the present invention is to provide functional bamboo wood of a kind of immobilized graphite-phase carbonitride and preparation method thereof, this bamboo wood has the functions such as the volatile organic contaminants such as good purifying formaldehyde, benzene, toluene and antibacterial, sterilizing in actual applications, for the pollutant adhering on it, easily removes; And improved to a certain extent that natural bamboo anti-mildew becomes, damages by worms, the performance such as rotten.
For achieving the above object, the present invention adopts following technical scheme:
The preparation method of the functional bamboo wood of a kind of immobilized graphite-phase carbonitride comprises the following steps:
(1) Outer part and inner part of the bamboo of bamboo wood is removed, and be placed in 103 ℃ of dry 24h of baking oven;
(2) get 5 ~ 10g, tri-chloro piperazines and 3 ~ 4g ammonium chloride and put into autoclave, add again 200 ~ 500 mL benzene, after stirring 30min, put into the bamboo wood of step (1), to passing into nitrogen in reactor, fully drive the air in reactor system away, and to applying the pressure of 30 ~ 40MPa in reactor, speed with 1 ~ 2 ℃/min makes the temperature in reactor rise to 250 ~ 300 ℃ again, and constant temperature, after constant voltage reaction 2 ~ 3h, after naturally cooling to room temperature, bamboo wood is taken out, and use successively hydrochloric acid, acetone wash products, then with distilled water cyclic washing bamboo wood until cleaning fluid be after neutrality, be placed in baking oven dries at 103 ℃, obtain the functional bamboo wood of immobilized graphite-phase carbonitride.
Remarkable advantage of the present invention is: the functional bamboo wood of immobilized graphite-phase carbonitride that the present invention makes has the volatile organic contaminant functions such as good purifying formaldehyde, benzene, toluene; There is the functions such as antibacterial, sterilizing, for the pollutant of attached thereto, easily remove; And improved to a certain extent that natural bamboo anti-mildew becomes, damages by worms, the performance such as rotten.The success of this technology, for the range of application of alleviating timber resource shortage, expansion bamboo wood, maintains sustainable development and has important practical significance.
