Description
Technical field
The present invention relates to a kind of method that bamboo material surface builds Calcium Carbonate super-drainage structure, belong to bamboo material and wooden
Material surface modifying technology field.
Background technology
Bamboo wood, timber are generally in nature, closely bound up with it with the life of people, and daily life be unable to do without these
Material.Bamboo wood and timber as a kind of reproducible natural resources and Study on Environment Compatible Materials, possess natural superiority and
There is DEVELOPMENT PROSPECT widely, but at present due to due to bamboo wood and timber self structure and development technique, its comprehensive profit
It is not high with rate.Due to bamboo wood and the natural defect of timber, such as inflammable, perishable, not hydrophobic, mechanical strength is little etc., make
They the application of fertile product and using being subject to certain restrictions.When using bamboo wood and timber, in order to be able to
Enough while its advantage is made full use of, go to avoid its shortcoming as far as possible, it is necessary to using some special physics or chemistry side
Method is modified to it, and while its performance is improved their application is also improved.Current some relatively common timber
Method of modifying have wood acetylation, timber modeling conjunction, heat_treated wood, wood compression, timber pickling, wood staining, timber curved
Bent and Wood Bleaching etc..With the progress and development of society, some new method of modifying, such as supercritical fluid processing have been explored
Technology, the solution of timber and modified using nanotechnology, these method of modifying have tempting prospect and powerful life
Power.Timber goes the mechanism for studying Wooden modifying using composite theory, especially as a kind of natural high molecular composite material
Timber has important Research Significance with the crosslinked action of chemical agent.By Wooden modifying, timber is set not only to possess original
Some characteristics also improve some other performances, and this possesses highly important meaning for the utilization of timber.
Calcium Carbonate has nano unit body, is the Jie Guan worlds between macrocosm and microcosmoss, with quantum
Effect, small-size effect, skin effect and fractal aggregation characteristic etc..By calcium carbonate material being molecularly dispersed in certain material
Surface matrix in form calcium carbonate composite material, its will present it is many uniqueness properties.And Calcium Carbonate is industry in the world
A kind of metaplasia is produced, powder body material of yield highest, purposes ten/extensively, particularly in recent years the ground such as Guangxi is compound to Calcium Carbonate
The research report of material is more and more more.Lot of documents shows, Calcium Carbonate because acting on very strong nanometer, can with many metals,
Inorganic and organic materials unconditionally produce very strong interaction, show excellent performance.But its technology of preparing development

Power is huge, and with deepening continuously of studying Calcium Carbonate and the further industrialization of calcium carbonate composite material production, it should
Will be more and more extensive with field.With society and expanding economy, people increasingly pursue the material with superior function, no
Existing material can be satisfied with, therefore, the modified of material will be also the main flow in following a period of time, unless replacement can be found
Material.Calcium Carbonate is not replaceable for the effect of material modification.
With reference to modified for bamboo wood, the meaning of timber and Calcium Carbonate are for the effect of material modification, using Calcium Carbonate to material
Material is modified the researcher that countries in the world industry-by-industry is attract as an emerging research field.Arrived with Calcium Carbonate
It is wood science research new trend in recent years among Wooden modifying and preparation feature wood base composite material, Calcium Carbonate is in wood
There are many applications during material is modified.
But in existing research, Calcium Carbonate is used in bamboo wood, timber field and mainly concentrated for anti-corrosive antibacterial, physical force
Modified, flame-retardant modified, Study on dimension stability etc. is learned, is related to for it rarely has in the research of surface super hydrophobic.For this purpose, of the invention
