Bamboo charcoal is the brand-new material that development in recent years is got up, and it not only has excellent characterization of adsorption, but also has functions such as radiation far infrared, release negative ion, electromagnetic shielding.Bamboo charcoal is applied to the concern that building materials have also received more and more people, is that 200510049855.4,200910153652.8,200910153653.2 priorities are respectively raw material complex functionality property ceramic tile with the bamboo charcoal like application number.At application number is to have reported preparation porcelain granules containing carbon and decorative material for wall surface in 200910100107.2,200910100625.4.Though the existing research of bamboo charcoal aspect building materials, its range of application still need be opened up.
Summary of the invention
The technical problem that the present invention will solve provides a kind of plasterboard that integrates absorption, radiation far infrared, release negative ion and preparation method thereof.
In order to solve the problems of the technologies described above, the present invention provides a kind of plasterboard, is made up of raw material and binding agent, and raw material is grouped into by the one-tenth of following weight content: 20～40% bamboo charcoals (bamboo charcoal powder) and 60～80% terra alba, binding agent accounts for 20～35% of raw material gross weight.
Improvement as plasterboard of the present invention: binding agent is 1～8% TiO for the solid phase weight content
2Colloidal sol.
Further improvement as plasterboard of the present invention: the particle diameter of bamboo charcoal is 20～45 μ m, and the particle diameter of terra alba is 150～250 μ m.
The present invention also provides the preparation method of above-mentioned plasterboard simultaneously, and raw material is grouped into by the one-tenth of following weight content: 20～40% bamboo charcoals (bamboo charcoal powder) and 60～80% terra alba, binding agent (TiO
2Colloidal sol) account for 20～35% of raw material gross weight; Carry out following steps successively:
1), bamboo charcoal mixed with terra alba stirs 1～12h, raw material;
2), in the resulting raw material of step 1), add TiO
2Colloidal sol mixes and stirs 1～4h; Get compound;
3), with step 2) the advanced horizontal high voltage moulding of the compound of gained, and then solidify last thermal treatment; Get plasterboard.
Improvement as the preparation method of plasterboard of the present invention: in the step 5): the pressure of high-pressure molding is 5～10Mpa; Said solidified temperature is 80～100 ℃, and the solidified time is 1～2h; Said heat treated temperature is 300～800 ℃, and heat treatment period is 1～3h.
In the present invention, the solid phase weight content is 1～8% TiO
2Colloidal sol can prepare according to " preparation and the photocatalysis performance of anatase octahedrite-rutile mixed crystal TiO2 colloidal sol " in 2008 " Rare Metals Materials and engineering " the 37th volume, published.
Plasterboard of the present invention, to be the contriver on the basis of the bamboo charcoal that studies for a long period of time, plasterboard material, bamboo charcoal powder and terra alba are carried out reasonably composite and get.Its advantage is: through the introducing of bamboo charcoal, and adopt rational grain size distribution to keep the pore passage structure of bamboo charcoal powder, make goods when having adsorptive power, also have the release negative ion, the far function of radiation.In addition, the introducing of TiO 2 sol is served as the normal temperature binding agent on the one hand, after thermal treatment, maintains good anatase crystal on the other hand, has given plasterboard certain photocatalysis characteristic.
The present invention; Through to the rational grain size distribution of raw material; Be filled in the micron order bamboo charcoal powder in the space of landplaster particle; The bamboo charcoal function is given full play to; And be the normal temperature binding agent with titanium dioxide; Prepare have absorption, radiation far infrared and discharge the plasterboard of negative ion, and it also has certain photocatalysis characteristic.
The present invention and above-mentioned disclosed prior art difference are:
One, in the above-mentioned prior art; Raw material has all used activated carbon, has realized that at present industrialized activated carbon is generally formed through charing and activation by non-renewable raw materials such as coal class, petroleum-type, timber etc., though adsorptivity is better; But its resource is non-renewable, and production cost is higher.It is raw material that the present invention adopts bamboo charcoal, and bamboo charcoal is by the direct charing gained of renewable resources bamboo wood, need not activation, and not only absorption property is good, and has the not available far-infrared radiation of activated carbon, discharges negative ion effect etc.Far-infrared engergy promotes the activation of human senility cell, accelerates blood circulation, improves the human internal environment.Discharge negative ion, neural, Ginseng Extract can relax.In addition, indoor, negative ion and airborne particulate matter bump against, and make it charged, and these charged particulate matter attached on wall, minute surface, the floor, reach the purpose that purifies air easily.Therefore bamboo charcoal is applied to the plasterboard material, many advantages are arranged.
Two, in the above-mentioned prior art, not open to raw material granularity in its technological process on the one hand, irrational granularity can the curing along with terra alba cause the duct of carbon is stopped up in the preparation process, makes it to lose water absorbability; On the other hand, plasterboard is not adsorbed maybe accordingly can characterize test with adsorptive power.
The contriver is in the invention process, and also find: the selection of the particle diameter of bamboo charcoal and the particle diameter of terra alba is very important, selects different particle diameters, and the performance of the plasterboard of gained has a lot of difference.Particle diameter is too big, the mechanical property meeting variation of plasterboard, even do not reach the GB requirement.Particle diameter is too little, then can cause the increase greatly of production cost, so the present invention chooses above-mentioned numerical value.
The plasterboard that the present invention produced reaches 90～170m through its specific surface area of test
2/ g discharges 800～1200/cm of negative ion
3, far-infrared radiation rate 87～91%.
The plasterboard that the 9.5mm that the present invention produced is thick, its longitudinal fracture load is 400～440N, the transverse breakage load is 160～190N, meets the requirement of GBT9775-2008 to breaking load.
The plasterboard that the present invention produced; Press GB 50325-2001 " civil building engineering indoor environmental pollution thing control standard ", GB/T 18204.26-2000 " method for determining formaldehyde in the public place air ", GB/T18204.25-2000 " ammonia measuring method in the public place air ", GB11737-89 " benzene, toluene and xylenes health test method-vapor-phase chromatography in the atmosphere of residential district " check, record its clearance 10～16%, to the clearance 11～19% of ammonia, to the clearance 10～20% of benzene to free formaldehyde.
Plasterboard of the present invention can be widely used in top ceiling, internal partition wall, body of wall cladding boards, acoustic panel, surface based laminate and the various decorative sheets etc. of various buildingss.
