Description
Technical field
The invention belongs to bamboo matter composite material technical field, it is related to a kind of bamboo matter composite material and its manufacturing method,
More particularly to a kind of high-strength bamboo matter composite wood in 3 D stereo surface and its manufacturing method.
Background technique
Bamboo wood is the most important forest reserves in China, and China's bamboo timber resource is abundant, and bamboo wood cultivated area and accumulation occupy
First place in the world is known as the title of bamboo kingdom.Compared with timber, bamboo wood has big intensity, growth and renewal speed fast, and bamboo wood is felled
Ecological environment will not be not only destroyed, the distinguishing features such as growth are more advantageous to.Therefore, development and utilization bamboo timber resource is wooden to reducing
Aptitude source is felled, and is ensured timber and ecological safety, is met the people and need Green Home material with irreplaceable role.
Currently, China's bamboo matter product is numerous, wherein Recombined bamboo is the most representational product occurred in recent years.Recombined bamboo is due to tool
Have that stock utilization is big compared with high, density and intensity, be suitble to the reasons such as scale industrial production, so that Recombined bamboo manufacture has become
China's scale, high added value develop and use an important channel of bamboo timber resource.But there is also bamboo utilizations for existing Recombined bamboo
Rate needs to be further increased (bamboo blueness and tabasheer utilize not yet), product density excessive (utilization of resources is unreasonable), quality not
Enough to stablize (bamboo beam unit size deviation is larger, so that impregnating uneven with slab Density Distribution), production is at high cost, product
The problems such as application field relatively narrow (be used primarily in Furniture manufacture, interior/exterior decoration field, and less in structural engineering field).Cause
How this, make full use of existing bamboo timber resource, develops stock utilization height, lower production costs, good decorating effect, application field
Wide bamboo matter new material has very important realistic meaning.
