Description

A kind of fiberboard with purifying formaldehyde function
Technical field
The invention belongs to wood-based plate field, and in particular to a kind of fiberboard with purifying formaldehyde function.
Background technology
Fiberboard also known as density board, be using wood fibre or other plant cellulose fiber as raw material, apply Lauxite or its Wood-based plate made of the adhesive that he is applicable.Fiberboard has that raw material sources are wide, and production efficiency is high, stable material quality（Even structure, Medium density, plate face is smoothly fine and smooth, easily carries out various facing processing, good stability of the dimension）The features such as, it is widely used in ground Plate, furniture, door, house fitting-up decoration, wallboard, dividing plate and packaging preferred material.Fast development and city with China's economy The continuous improvement of rate, steady quality, environmental protection grade height, meet differentiated demand and the fiberboard with safety and environmental protection function Product has the wide market space.
Chinese patent（201510695858.9）With（2000910071340.2）Individually disclose and use bamboo charcoal and activated carbon Purify the formaldehyde in air；Chinese patent（201410035319.8）Disclose using the formaldehyde in titanium dioxide purification air, In summary, some formaldehyde eliminating agents are generally added in fiberboard at present, reach the purpose for removing formaldehyde, its main method bag Include：Physisorphtion, photocatalyst method and chemical method.Physisorphtion is limited by adsorbance, and the term of validity is short, or even produces two Secondary pollution.Photocatalyst method by night it is unglazed limited, when not having light, photocatalyst does not just play a role.Chemical method refers to use certain The material that solid and gas heterogeneous reaction can occur with formaldehyde for kind is added in fiberboard, fiberboard is had the work(of absorption decomposing formaldehyde Can, its addition and reactivity determine purifying formaldehyde efficiency and the term of validity.
The content of the invention
The technical problems to be solved by the invention are to provide the fiberboard with purifying formaldehyde function, to realize above-mentioned mesh , the present invention takes following process technology scheme：
It is described comprising wood fibre, adhesive and activated carbon the invention provides a kind of fiberboard with purifying formaldehyde function Wood fibre weight 5-10% activated carbon is evenly distributed in fiberboard；Activated carbon surface and/or activated carbon the hole table Face is provided with one layer of film being made up of Nie Palladium alloys, aluminum oxide and titanium dioxide, and the film thickness is 2-5 molecular layer.
There are a Ceng Nie Palladium alloys and aluminum oxide using electrophoresis grafting on the surface of the activated carbon, its thickness is 1-2 Molecular layer；There is layer of titanium dioxide using electrophoresis grafting on the surface of Ni-Pd alloy, its thickness is 1-4 molecular layer.
The activated carbon is cocoanut active charcoal, and particles are 12-30 mesh, and specific surface area is 1050-1200 m2/ g, it is sub- Methyl blue adsorptive value is 200-225mg/g.
The trade mark of the Nie Palladium alloys is PdNi40。
The aluminum oxide is made up of 40%-50% γ-Al O and 50%-60% α-Al O.
The titanium dioxide is anatase titanium dioxide.
Free formaldehyde in air, is adsorbed onto by a kind of fiberboard with purifying formaldehyde function of the present invention using activated carbon In its surface and hole, and form alternate magnetic field using Nie Palladium alloys and aluminum oxide and electric field excites titanium dioxide, will adsorb Degradation Formaldehyde Cheng Shui and carbon dioxide in activated carbon surface and/or activated carbon pore surface and hole, reach purifying formaldehyde Purpose, overcome the physisorphtion term of validity is short, may have the problem of secondary pollution, solve photocatalyst light requirement photograph condition without The problems such as the problem of illumination does not play a role and chemical method are limited by concentration of formaldehyde size.
With reference to specific embodiment, the invention will be further described, not limitation of the present invention, every according to this The equivalent substitution of any this area that disclosure of the invention content is carried out, belongs to protection scope of the present invention.
Brief description of the drawings
Fig. 1 has the fiberboard schematic diagram of purifying formaldehyde function
Fig. 2 activated carbon structure schematic diagrames
In figure：1 is wood fibre, and 2 be activated carbon, and 3 Nie Palladium alloys, 4 be aluminum oxide, and 5 be titanium dioxide.
Embodiment
A kind of fiberboard with purifying formaldehyde function, includes wood fibre（1）, adhesive（Not shown in figure）And activity Charcoal（2）, the cocoanut active charcoal (2) of wood fibre weight 10%, particles 12-30 are evenly distributed in the fiberboard Mesh, specific surface area are 1100 m2/ g, methylene blue adsorption value are 210 mg/g, and electrophoresis is used on the surface of cocoanut active charcoal Grafting has a Ceng Nie Palladium alloys（3）And aluminum oxide（4）, Nie Palladium alloys（3）The trade mark be PdNi40, aluminum oxide（4）By 40% γ- Al O and 60% α-Al O compositions；In Ni-Pd alloy（3）And aluminum oxide（4）Surface using electrophoresis grafting have one layer it is sharp Titanium-type titanium dioxide（5）, its thickness is 3 molecular layers.
The mechanism of fiberboard degradation of formaldehyde of the present invention：Cocoanut active charcoal is porous material, and specific surface area reaches 1100 m2/ G, methylene blue adsorption value are 210 mg/g, can by air or fiberboard glue-line release free formaldehyde be adsorbed onto its surface or In different size of space, the titanium dioxide Nie Palladium alloys and aluminum oxide of activated carbon surface or pore surface is set to form alternating Magnetic field and electric field excite down, Degradation Formaldehyde Cheng Shui in activated carbon surface and/or activated carbon pore surface and hole will be adsorbed onto And carbon dioxide, reach the purpose of purifying formaldehyde, be two because Ni-Pd alloy and aluminum oxide can form alternate magnetic field and electric field The degraded of titanium oxide provides kinetic energy, overcomes that the simple activity carbon adsorption method term of validity is short, may have the problem of secondary pollution, solve The problem of condition no light that titanium dioxide light requirement shines does not play a role and chemical method are limited etc. by concentration of formaldehyde size and asked Topic.
Embodiment two：
A kind of fiberboard with purifying formaldehyde function, includes wood fibre（1）, adhesive（Not shown in figure）Lived with coconut husk Property charcoal（2）, the cocoanut active charcoal of wood fibre weight 8% is evenly distributed in fiberboard（2）, particles are 20 mesh, compare table Area is 1200 m2/ g, methylene blue adsorption value 225mg/g.In cocoanut active charcoal（2）Surface have a Ceng Nie Palladium alloys （3）And aluminum oxide（4）, its thickness is 3 molecular layers；In Ni-Pd alloy（3）And aluminum oxide（4）Surface have one layer of anatase titanium dioxide two Titanium oxide（5）, its thickness is 2 molecular layers.
