Description
Technical field
The invention belongs to building material technical field, more particularly to a kind of high-weatherability low water absorption carbon wood composite material.
Background technology
Similar with this product at present has wood plastic composite and timber, stone material, and wood plastic composite is through being to utilize poly- second
Alkene, polypropylene and polyvinyl chloride etc. with wood powder, rice husk, the useless string such as stalk mix the modeling such as extruding, molding, injection moulding
The section bar that material processing technology is produced is referred to as Wood-plastic profiles, is mainly used in the industries such as building materials, furniture, logistics packaging.Wood plastic sectional
Material has good processing characteristics, good strength character, corrosion resistant performance, and service life is grown, excellent adjustable energy, these
Performance makes plastic-wood section substitute solid wood, stone material, and more and more extensive application is obtained in building trade.Make for a long time outdoor
With, it is necessary to be subjected to constantly being subjected to the friction of hard thing, the invasion and attack of spot and Exposure to Sunlight, wind, drench with rain etc., it is necessary to its have it is good
Anti-wear performance, weather resistance and extremely low water absorption rate, but Wood-plastic profiles are absorbing water, it is wear-resisting, weather-proof etc. to need further
Improve, common water suction cracking, mouldy in large batch of application project domestic at present, fades, and occurs situations such as surface tear, influences
The further genralrlization application of Wood-plastic material.
The earth possesses a carbon cycle system in itself, and carbon can be by plant, soil, under ocean and other natural processes deposition
Come.But the current serious excess load of these systems.Biological carbon can deposit 10 to 20 hundred million tons of carbons every year.It this
Kind mystery, unique characteristic, become the most popular field of research climate change.For example, the life after sludge carbonization
The content of carbon is 40% in thing carbon, and surplus is the various trace elements and organic matter etc. such as nitrogen, phosphorus, potassium.
The content of the invention
The purpose of invention is in view of the above-mentioned problems, providing a kind of high-weatherability low water absorption carbon wood composite material, is solved
Wood plastic composite of the prior art anti-wear performance and weather resistance in outdoor long-time use are low, while reduce type
