Description
Technical Field
The invention relates to ceramic wood, in particular to ceramic wood used for furniture, decorative materials, building materials and artworks.
Background
The application of the wood is very wide, such as furniture, decorative materials, building materials, artworks and the like. For wood used for a long time, anticorrosion and waterproof treatment is generally needed, and in the above treatment process, anticorrosion and waterproof materials are usually adopted to treat the wood, but the existing anticorrosion and waterproof materials are only on the surface of the wood and are difficult to enter into the gaps of the wood, so that once the anticorrosion and waterproof materials on the surface of the wood are damaged, the anticorrosion and waterproof properties of the wood are reduced, and the wood is easy to deform, mildew and the like. The existing anticorrosive wood on the market is treated by the preservative, is not waterproof, starts to corrode and mildew once the preservative fails, and is not a real anticorrosive wood.
Disclosure of Invention
The invention aims to provide a monomer entering type ceramic wood and a manufacturing method thereof.
In order to achieve the purpose, the manufacturing method of the monomer-entering type ceramic wood is characterized by comprising the following steps:
(1) preparing a storage, and adding acetic acid into the storage;
(2) putting the wood into a storage with acetic acid, sealing the storage for 10-24 hours at normal temperature, and allowing the acetic acid to enter the wood;
(3) taking out the wood after the step (2) is finished, putting the wood into a stainless steel closed storage, controlling the pressure in the stainless steel closed storage to be 0.5-1MPa, controlling the temperature in the stainless steel closed storage to be 140-180 ℃, then introducing ethylene and oxygen into the stainless steel closed storage, and introducing the ethylene and the oxygen into the wood under the action of the pressure to generate vinyl acetate in the wood;
(4) putting the wood in the step (3) into a mixed solution of a solvent with a chain transfer constant less than 5 and an initiator, and soaking the wood for 8-10 hours in an environment with the pressure of 2-4MPa and the temperature of 30-50 ℃;
(5) taking out the wood, and generating a high molecular weight polymer at the normal temperature, wherein the high molecular weight polymer and the wood fiber form a net structure.
The monomer entering type ceramic wood is formed by filling high molecular weight polymer and wood fiber into gaps of wood to form a net structure.
Further, the weight percentages of acetic acid, ethylene, oxygen, solvent and initiator are as follows:
20 to 30 percent of acetic acid
16 to 25 percent of ethylene
7 to 12 percent of oxygen
35 to 50 percent of solvent
0.1 to 0.5 percent of initiator.
Further, the solvent is one of chloroform, dichloromethane, methyl acetate and vinyl acetate.
Further, the initiator is benzoyl peroxide.
Wood is a naturally growing organic material, consisting of high molecular substances and low molecular substances. The main substances forming the wood cell wall are three high polymers, wherein the three high polymers are cellulose, hemicellulose and lignin respectively and account for 97-99% of the weight of the wood.
Cellulose is a linear natural high molecular compound formed by connecting a plurality of D-grape pond groups through l, 4- β -glucoside bonds, plays a role of a skeleton in wood cell walls, generally accounts for more than 40% of wood components, and accounts for about 50% of the wood cells.
The hemicellulose is a substance tightly connected with cellulose in the wood cell wall, plays a role of bonding, mainly consists of five neutral monosaccharides such as hexose, mannose, galactose, pentose and an arable leveler, and has a molecular chain far shorter than that of the cellulose and a certain branching degree.
Lignin is an aromatic compound consisting of phenylpropane units, the last high polymer deposited in the cell wall during cell formation, which interpenetrates cellulose and serves to strengthen the cell wall.
Based on the structure, the wood has a plurality of gaps.
The invention has the beneficial effects that:
(1) according to the manufacturing method, in the wood, the high molecular weight polymer and the wood fiber form a net structure, the high molecular weight polymer fills gaps in the wood, the original internal structure of the wood is changed, the wood is good in waterproof, mildew-proof, anticorrosion and mothproof performances, and the ceramic wood is good in size stability because no gap exists in the ceramic wood. Because the high molecular weight polymer is filled in the wood instead of the surface layer, the inner layer and the outer layer of the ceramic wood are consistent, and the ceramic wood is not different from the inner layer of the ceramic wood after the outer layer of the ceramic wood is polished. For the above reasons, the ceramic wood of the present invention is durable and has a long life.
(2) In the ceramic wood manufacturing process, firstly, acetic acid enters the wood, and a vinyl acetate monomer is formed in the wood, the reason for adopting the mode is that the acetic acid is easier to enter the wood than the vinyl acetate, the technical problem of incomplete filling of wood gaps is avoided, in addition, because the vinyl acetate easily generates polymerization reaction, and before the vinyl acetate does not enter the wood, the vinyl acetate needs to be controlled to generate polymerization reaction, therefore, the acetic acid with stable performance is adopted as one of the raw materials, and the vinyl acetate is formed in the wood.
(3) In order to reduce the chance of vinyl acetate polymerization during the formation of vinyl acetate in the wood, the reservoir was closed with stainless steel.
(4) After vinyl acetate is formed in the wood, a solvent and initiator are added in order to form a high molecular weight polymer. In addition to three fractions of chain initiation, chain extension and chain termination, vinyl acetate polymerization reactions in which chain transfer should be minimized, such as to form high molecular weight polymers, are also known to occur due to RCH2CHOCOCH3The growing active chain is easily transferred to the solvent, to the monomer and to the polymer macromolecule already formed. For transfer to the solvent, see the following equation:
if A is.Inactive, non-reactive with the monomer, or having a very low reaction rate if A.Is active and is susceptible to the reaction of monomers to re-initiate polymerization, and therefore, it is important to control the chain transfer reaction solvent, including the amount and type of solvent used, and the amount of solvent used is [ AB]/[M]Ratio determination according to the formula
It can be seen that the degree of polymerization is determined primarily by the Cs of the solvent, but also by the amount of solvent used, whereas in the present invention it is desired to obtain a material with a higher degree of polymerization, and therefore the initiator and amount used in the present invention. On the upper partDP of the formula is the degree of polymerization, DP0The average polymerization degree of the polymer in the absence of a solvent, [ AB ]]As solvent concentration, [ M ]]Cs is the initiator chain transfer constant, is the monomer concentration.
(5) The decomposition temperature of the benzoyl peroxide is 105 ℃, the polymerization temperature is too high in the polymerization process, the polymerization crystallinity of the vinyl acetate is low, and the hot water resistance of the vinyl acetate is poor, so that the polymerization crystallinity can be improved and the hot water resistance of the vinyl acetate can be improved by adopting a lower polymerization temperature in the invention.
