Description
Technical field
The present invention relates to a kind of preparation method and products thereof of nano inorganic carbonized wood and use, belong to the wood processing technique field.
Background technology
Degree of depth carbonized wood since its at the anti-cracking of anticorrosion, hangfire, absorb pernicious gas and reduce aspects such as equilibrium moisture content and all have very outstanding performance, be referred to as do not ftracture, not living bacterium not snake, the not on fire and timber that purifies air.Therefore, can access more widely and to use, as the material that is used for timber compoment, floor etc.
Existing degree of depth carbonized wood is to carry out degree of depth charing processing by high temperature to obtain carbonized wood mostly, the degree of depth of physical dimension is handled and is not only in described degree of depth charing, it mainly is the depth that has comprised the charing degree, it is the size of carbonization degree, in general the temperature in charing stage is more high, time is more long, and then char depth is more dark.As Chinese patent application (publication number: CN101069972A) disclose a kind of method of charred wood by heat treatment, earlier that the material of moisture content≤12% is dry according to a conventional method, be The pre-heat treatment under 50 ℃～80 ℃ the condition in temperature again, speed with 10 ℃/h～18 ℃/h is warming up to 95 ℃～105 ℃ again, then being warming up to 120～130 ℃ with the speed of 3 ℃/h～8 ℃/h is dried to moisture content and almost drops to 0%, then, processing obtains carbonized wood through high temperature carbonization again.But the defective that also has following several respects through the carbonized wood that charing is handled: first, aspect moisture-resistant expands, though bulking factor reduces significantly, but in rainy season, indoor relative humidity might reach more than 95% or after water on the carbonizing wood floor board is repeatedly cleaned still serious deformation can occur; The second, color absorption is caused being not easy to cleaning soon, stain resistance is poor; The 3rd, handle back intensity and case hardness decline through degree of depth charing, cause the surface to go up carbon powder and come off easily.Often make up at the top finishing paint at above-mentioned second and three defective is existing, and thereby the pore that has caused stopping up carbonized wood behind the employing coating has lost the ability that absorbs pernicious gas, and often there is the harm of toxic gases such as discharging toluene, dimethylbenzene and formaldehyde in paint.
Summary of the invention
The present invention is directed to above problems of the prior art, a kind of preparation method and products thereof of nano inorganic carbonized wood is provided and uses, can realize the effect of high strength and high rigidity.
One of purpose of the present invention is achieved by the following technical programs, a kind of preparation method of nano inorganic carbonized wood, and this method may further comprise the steps:
A, degree of depth charing are handled: earlier timber board is put into carbonizing kiln and obtained ovendriedwood sheet material through the super-dry processing earlier, be warming up to 195 ℃～220 ℃ insulations again and carry out degree of depth charing processing;
B, cooling moisture-retaining are handled: after degree of depth charing processing finishes, be cooled to 110 ℃～120 ℃ and add wet process, the interior humidity of carbonizing kiln is remained on more than 95%, be cooled to 40 ℃～60 ℃ processing of preserving moisture again and make the moisture content of carbonized wood reach fibre saturated point, obtain wet carbonized wood;
C, nano inorganic processing: the carbonized wood that will wet is earlier packed in pressure irritates, and adds inorganic nano additive colloidal sol wet carbonized wood is immersed in the inorganic nano additive colloidal sol fully, exert pressure to the 8～10kg/cm in pressure is irritated
2Make in the wet carbonized wood of inorganic nano additive colloidal sol infiltration; Drain the inorganic nano additive colloidal sol in the pressurized tank again, behind the wet carbonized wood surface of scouring; Be forced into 8～10kg/cm again
2And be warming up to 40 ℃～50 ℃ and carry out the phase I and handle; Then, unload and be depressed into normal pressure, be warming up to 150 ℃～170 ℃ again and carry out the second stage processing, the ejecting plate of lowering the temperature again obtains the nano inorganic carbonized wood.
Among the preparation method of nano inorganic carbonized wood of the present invention, described timber board is to adopt solid wood board, as directly being that material is made corresponding timber board etc. with the oak.The present invention is by after handling timber board earlier through degree of depth charing, can make the timber molecular structure obtain in various degree reorganization, makes the basic molecular structure glucosyl group (C of timber board
