Description
Technical field
The present invention relates to ceramic wood and its manufacturing methods.Especially with arrive furniture, ornament materials, construction material, art
Ceramics wood on product.
Background technique
The application of timber is very extensive, such as furniture, ornament materials, construction material, the art work.For being used for a long time
Timber for, generally require and do anti-corrosion and waterproof processing, in carrying out above-mentioned treatment process, generally use anti-corrosion waterproof material
Timber is handled, but current anti-corrosion waterproof material is only on the surface of timber, it is difficult to it enters in the gap of timber, this
Sample, once the anti-corrosion waterproof material of wood surface is destroyed, then the preservation of timber against decay, waterproof performance decline, timber are easy to appear change
Shape, it is mouldy phenomena such as.The anticorrosive wood of market at present is handled using preservative, non-watertight, once preservative fails, is begun to
Burn into is mouldy, is not real anticorrosive wood.
Timber is a kind of organic material of spontaneous growth, is made of polymer substance and lower-molecular substance.It is thin to constitute timber
The main matter of cell wall is three kinds of high polymers, and three kinds of high polymers are respectively cellulose, hemicellulose and lignin, accounts for wood weight
97%-99%.
Cellulose is by many mono- grape pool bases of D by l, 4- β-glucoside linear natural polymer chemical combination made of being keyed
Object plays skeleton function in wood cell wall, typically constitutes from 40% of wood components or more, and 50% or so is accounted in wood cell.
Its chemical property and supramolecular structure have a major impact wood property and processing performance.
Hemicellulose is cementation to be played, mainly by hexose, sweet with the close-connected substance of cellulose in wood cell wall
Reveal five kinds of neutral monosaccharides compositions such as sugar, the gala pool, pentose and Arabic a kind of farm tools, strand is short more than cellulose, and has one
Fixed branch degree.
The aromatic compound that lignin is made of phenylpropane units is deposited on cell in cell formation process
Last a kind of high polymer in wall, they run through mutually cellulose, play a part of to strengthen cell wall.There are three types of basic for lignin
Structure, i.e. guaiacyl structure, lilac based structures and p-hydroxyphenyl structure mainly include alcoholic extract hydroxyl group, phenolic hydroxyl group, carbonyl, carboxylic
A variety of chemical reactions can occur for base and methyl etc..Isocyanate resin fills timber gap primarily from isocyanate group
Reacting between active hydrogen a large amount of in timber is formed by chemical bond, such as the hydroxyl in cellulose, hemicellulose rope, in lignin
Phenolic hydroxyl group, further include a large amount of water contained in timber, they can react with isocyanates, this is isocyanates
Base and substrate active hydrogen reaction form chemical bonds；Secondly, the big polar group of isocyanate resin and the oxygen-containing, nitrogen of substrate etc.
The asking for product for forming Hydrogenbond, isocyanate group itself or isocyanate group and isocyanate group and timber can produce self-crosslinking
Reaction.But in practical applications, the activity of NCO group is very big, directly penetrates into polyisocyanates in timber, NCO base
Group's chance quickly reacts with water, active hydrogen, when to isocyanates not completely into in timber, just has occurred that
Solidification, in this way, polyisocyanates is just difficult to completely penetrate to be filled up completely the gap in timber in timber, in this way, current
Polyisocyanates can only be also confined in the field of adhesive.
Summary of the invention
The ceramic wooden and manufacturing method based on closed NCO that the object of the present invention is to provide a kind of, utilizes pottery of the invention
Porcelain wood and the ceramics wood obtained by the manufacturing method, anti-corrosion and waterproof, mothproof, dimensionally stable, service life as ceramics
Long, performance is good, so that timber is not easy to deform, is mouldy, while durable, and the inner layer of ceramics wood is consistent with outer layer, Bu Huiyin
Cladding material is different with internal layer ceramics wood after being buffed off.
In order to achieve the above objectives, a kind of ceramics wood based on closed NCO group, including timber, in the gap of timber
Filled with the polyurethane for forming reticular structure with lumber fibre, the polyurethane is to be reacted by enclosed type performed polymer with water
High molecular polymer, enclosed type performed polymer is reacted by polyisocyanates and polyether polyol or polyester polyol forms performed polymer
Then blocking agent NCO group is used；The temperature for forming enclosed type performed polymer is 60-100 DEG C, NCO base in enclosed type performed polymer
The content of group accounts for the 5-20% of enclosed type performed polymer, and enclosed type performed polymer molecular weight is 1000-5000, and enclosed type performed polymer contains admittedly
Measure 80% solvent of >：Water, the above percentage are weight percentage.
The above-mentioned manufacturing method based on closed NCO ceramics wood includes the following steps：
(1) performed polymer is prepared, polyisocyanates and polyether polyol or polyester polyol are reacted；
(2) sealer is added in performed polymer, forms enclosed type performed polymer with blocking agent NCO group, reaction equation is：
(3) water is added in enclosed type performed polymer and forms maceration extract；
(3) by timber pickling in maceration extract, maceration extract entered wood by 12-24 hours under the pressure of 1-10MPa
In material；
(4) timber by dipping is taken out, is then placed in heating kettle, heating 10- is carried out to the timber by dipping
20 hours, heating temperature be 100-180 DEG C, heating use segmentally heating, wherein 100-120 DEG C heating 4-8 hours, 120-150
DEG C heating 4-8 hours, 150-180 DEG C heating 2-4 hours, during heating, closed NCO group is unsealed, and is occurred simultaneously
Chemical reaction forms lumber fibre in timber and constitutes the polyurethane of reticular structure and ceramics wood is made；The chemical reaction of generation
Mainly have：
Further, one of polyisocyanates TDI, MDI, HDI, IPDI or several.
Further, sealer is one of imidazoles, gaultherolin, methyl p-hydroxybenzoate.
It further, include reacting the portion formed with hydroxyl in ceramic wood and phenolic hydroxyl group by polyisocyanates in ceramics wood
Point.
Further, it is taken away by moisture for partially enclosed dose.
In the present invention, based on the characteristic in timber with hydroxyl, phenolic hydroxyl group and a large amount of water, and in polyisocyanates
The activity of NCO group has unusual height, for this purpose, the present invention first closes NCO group, enclosed type performed polymer and water is allowed to press
Completely into after in the gap to timber in the time of power and control, NCO group is unsealed by heating, in the mistake of deblocking
Cheng Zhong, NCO group, which react with water, hydroxyl, phenolic hydroxyl group, is formed by curing polyurethane, in the curing process, polyurethane and timber
Fiber forms reticular structure, and in deblocking and solidification process, polyisocyanates fills timber gap primarily from isocyanates
Reacting between base and active hydrogen a large amount of in timber is formed by chemical bond, such as the hydroxyl in cellulose, hemicellulose rope, lignin
