Description
Technical field
The present invention relates to a kind of preparation method of bamboo wood composite wood, particularly a kind of method of utilizing bamboo surplus material of processing preparation room external application bamboo wood composite wood.
Background technology
China's bamboo resource is abundant, and bamboo kind, area, bamboo wood output all occupy first place in the world.The advantage of resource, the input in science and technology that day by day increases, and the industry guide policy of country makes the bamboo industry of China obtain swift and violent development.2005 bamboo annual value of production have reached 59,800,000,000 yuan, and average annual amplification is more than 20%, and professionals surpasses more than 3,500 ten thousand, about 10.5 hundred million dollars of year foreign exchange earning.Bamboo industry has been called one of four large rising industries of China's forestry, and has in the international market the comprehensive competition advantage.
Bamboo is a kind of typical, the organism with excellent mechanical performances that nature exists.Hurricane can blow the large tree of neat waist disconnected easily, but can not make bamboo fracture.Its reason mainly contains following 3 points: 1) bamboo fiber material intensity height, good springiness and density are little, and specific strength is 3～4 times of steel, has higher tensile strength and compression strength; 2) the bamboo cross section is annular, and outer bent face tension and interior bent face pressurized have stronger bending rigidity; 3) the outside hoop at ring place and inner diaphragm plate can increase loaded area, also can improve the bearing capacity of thick bamboo tube simultaneously.Yet the bamboo processing utilization rate only has about 30%, and most bamboo woods are wasted.
Therefore, in order to take full advantage of bamboo surplus material of processing, utilize the adhesive glue applying method, preparation bamboo wood composite wood.The enforcement of this patent can increase substantially utilization rate of bamboo, promotes the universal utilization of bamboo wood composite wood technology, realizes the sound development of bamboo processing industry, reach economize on resources, the purpose of protection of the environment.
Summary of the invention
Technical problem to be solved by this invention provides the preparation method of the bamboo wood composite wood that a kind of operating procedure is simple, controllability good, cost is low.
In order to solve the problems of the technologies described above, the preparation method of a kind of bamboo wood composite wood provided by the invention is to be made of following steps:
(1), pre-treatment of raw material: according to volume ratio V
