Abstract
The present invention relates to environment-friendly sheet technical field, especially a kind of Environmental-protection bamboo carbon slab and its preparation process, environmental bamboo charcoal composite plate.The Environmental-protection bamboo carbon slab includes following component by mass parts: 20~60 parts of bamboo charcoal powders；15~30 parts of plant fibers；10~60 parts of resin-oatmeals；2~5 parts of stabilizers；0.3~1.5 part of lubricating grease；2~3.5 parts of phase solvents；3~5 parts of reinforcing agents；10~30 parts of negative ion powders.The Environmental-protection bamboo carbon slab, itself can also be adsorbed and the harmful substances such as degradation of formaldehyde, sulfide, benzene without containing harmful substances such as formaldehyde；It is heated by its processing technology Pyatyi degression type, can guarantee that material sufficiently merges, not only increase the hardness of plate, and adsorbed and the duration of degradation increases, have the characteristics that nuisanceless, high-environmental, pollution-free, Ke Xunhuanliyong；Composite plate not only increases the contact area of bamboo carbon plate and air, and fastness increases, more beautiful, improves the market competitiveness.
Description
Technical field
The present invention relates to environment-friendly sheet technical field, especially a kind of Environmental-protection bamboo carbon slab and its preparation process, environmental bamboo charcoal
Composite plate.
Background technique
With the fast development of real estate industry, a variety of plates such as wood-based plate, solid wood composite board are widely used in furniture
The fields such as manufacture, interior decoration.Wood-based plate, solid wood composite board are mainly mixed in a certain ratio by forestry products residue and adhesive
It is suppressed by high pressure, a large amount of strong (VOCS) volatile organic matter smells can be discharged, be formaldehyde, benzene, dimethylbenzene
Etc. harmful substances pollution main source.Formaldehyde is to the harm of human body other than causing irritation chronic disease, moreover it is possible to sky
Ionic chloride reaction in gas generates carcinogenic substance --- dichlormetbylether, causes house renovated at present can not be immediately
It lives, needs the phase buffer of some time.
In addition, existing building indoor hardware fitting is typically all to use the materials such as ceramic tile, marble, white gypsum or albarium
Material can not realize health-care effect although these materials can achieve the effect that beautiful and durable, will not be to environmental protection
Advantageous effects and influence are generated, can not really solve the problems, such as the living environment quality of the mankind.And the bamboo to circulate on the market at present
