Abstract
The utility model provides a fiberboard with the function of self-absorbing formaldehyde, which comprises a wood fiber and an active carbon. The wood fiber and the active carbon are bonded together by an aldehydes adhesive, the using volume of the adhesive is within 9% to 12% of the mass ratio of the wood fiber, and the using volume of the active carbon is within 2% to 30% of the mass ratio of the wood fiber. The fiberboard is novel; in the manufacturing process of the board, a certain quantity of active carbon contents with the absorbing function are added, so that the fiberboard can have the function of self-absorbing the dissociative formaldehyde (harmful gas) in the board for a long time, thereby reducing release of the formaldehyde in the board and lessening pollution of the formaldehyde to environment; meanwhile, the fiberboard has the functions of deodorizing and preventing corrosion, dampness as well as mildew, and has the advantages of high absorbing efficiency, good absorbing effect, low cost, no toxicity, no side effects and the like.
Description
(1) technical field
The utility model belongs to functional form wood-base fibre and particle panel material and technical field of composite materials, is specifically related to a kind ofly have from adsorbing the fiberboard of formaldehyde function.
(2) background technology
At present, the employed artificial board of interior decoration mainly comprises fiberboard, particieboard, core-board, glued board, and these several big class artificial boards are used to make furniture, door and window, cabinet, floor and all kinds of decoration in a large number, are widely used in family and public place.Wherein, fiberboard is various a kind of wood-based plates of making in the plate near natural timber, its even structure, density is moderate, and the plate face is smoothly fine and smooth, carrying out various facings easily handles, dimensional stability is good, and sandwich layer is even, and the surface of sheet material and edge have favorable mechanical processing and moulding processability simultaneously, the gauge specifications vary is many, can satisfy multiple needs and is used in a large number in finishing; Simultaneously, fiberboard is with every physical property of its excellence, be widely used in indoor and outdoor dress horizontal stroke, office, high-grade family property, sound equipment, sedan limousine upholstery, the making material that also can be used as computer room antistatic floor, skirting, antitheft door, wallboard, dividing plate etc., or the good material of package.Replace high-grade hardwood in recent years especially and directly be processed into composite floor board, consolidated floor etc., be widely used in interior decoration and decorate, obtain user's favorable comment the service life of its bright and clean surface, solid quality, overlength.
The manufacturing technique requirent of fiberboard uses the adhesive of certain metering.Because formaldehyde has stronger cohesive, also have the timber intensity of raising and insect protected, corrosion-resistant function, so adopt formaldehyde and other raw materials synthetic in the used adhesive of artificial board, kind mainly contains urea-formaldehyde resin adhesive, phenolic resin glue, amino formaldehyde resin and melamine---formaldehyde resin adhesive.Because the Lauxite low price, cohesive force is good, and curing rate is fast, and viscosity is low during high concentration, and colourless or very slight color is good with the Combination of water, is easy to modulate proper viscosity, and is easily manufactured, and the wood-based plate more than 80% is with all using urea-formaldehyde resin adhesive as adhesive.But the urea-formaldehyde resin adhesive that contains free formaldehyde in the urea-formaldehyde resin adhesive and solidified still can slowly be degraded and release formaldehyde for a long time.There are some researches show that the release period of formaldehyde generally was 15 years in the wood-based plate.
Formaldehyde (HCHO) has another name called formaldehyde, colourless gas, and the protoplasmic poison material has pungent penetrating odor.The World Health Organization is assert, formaldehyde is the carcinogen of high-risk, human body is had great harm, but comprise allotriosmia, stimulation, allergy, abnormal pulmonary function, immunologic dysfunction, central nervous system unusual in addition also the inhereditary material in the damaging cells cause fetal anomaly etc.
(3) summary of the invention
The purpose of this utility model is to provide a kind of absorbing formaldehyde function that has, while absorption efficiency height, advantages of good adsorption effect, and also with low cost, the fiberboard of formaldehyde function is adsorbed in having of no side effects certainly.
The purpose of this utility model is achieved in that it comprises wood fibre and active carbon, wood fibre and active carbon are connected together by gluing, the adhesive consumption is 9%～12% of a wood fibre mass ratio, and activated carbon dosage is 2%～30% of a wood fibre mass ratio.
The present invention also has some technical characterictics like this:
1, described wood fibre and active carbon by adhesive through colding pressing and the hot pressing aftershaping;
2, described adhesive is the aldehyde adhesive stick;
3, described active carbon is arranged in the middle of the wood fibre;
4, described active carbon is crisscross arranged between wood fibre.
The present invention is a kind of tencel plate, in the sheet material manufacture process, add a certain amount of active carbon composition with adsorption function, make it have for a long time the function of free formaldehyde (pernicious gas) in the adsorbent voluntarily, can reduce the release of formaldehyde in the sheet material, reduce the pollution of formaldehyde, make fiberboard have the function of anticorrosion, moistureproof, deodorizing, mildew-resistant simultaneously environment.
The present invention utilizes the charcoal absorption principle, will have adsorbing active carbon powder or particle and add in the wood fibre board, makes active carbon can both effectively adsorb the pernicious gas that essential fiberboard discharges in the whole life cycle of fiberboard.Strengthen the performance of essential fiberboard insect protected, anticorrosion, moistureproof, deodorizing, mildew-resistant simultaneously.The technical solution adopted in the present invention has been utilized the absorption principle of active carbon, absorption efficiency height, advantages of good adsorption effect, and also with low cost, no side effects.Method with pernicious gas in the existing reduction fiberboard sheet material is compared, and can not give birth to secondary pollution and purification efficiency height, and sheet material is had from adsorbing function.Increase the active carbon operation of mating formation in the production technology scheme, other operations and equipment are all constant.
The present invention has reduced the pernicious gas burst size of the wood fibre board that uses the manufacturing of aldehyde adhesive stick, has increased the security that fiberboard uses, and has enlarged the function of use of fiberboard, reduces environmental pollution and treatment cost.After tested, added the fiberboard of active carbon powder or particle, its burst size of methanal can reduce 10～30%.
(4) description of drawings
Fig. 1 is the even distribution grid equipment structure of an active carbon schematic diagram, and Fig. 2 is the plate construction schematic diagram that active carbon is positioned at the sheet material central core,
Fig. 3 is the plate construction schematic diagram that active carbon and wood fibre are interspersed.
(5) specific embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments:
Embodiment 1:
In conjunction with Fig. 1, present embodiment mixes wood fibre 3, aldehyde adhesive stick 1 earlier with active carbon 2, mats formation then, through colding pressing and the hot pressing aftershaping.
