The furniture prepared by the method has bright color, obvious texture and vivid appearance, achieves the effect of simulating precious wood, and improves the grade and the economic value of the furniture.
Description
Technical Field
The invention belongs to the technical field of furniture processing and manufacturing, and particularly relates to a method for producing high-grade furniture by using a rosewood-imitating process.
Background
The rosewood furniture is outstanding in furniture, but cannot be popularized in the public due to the scarcity of wood, price and the like. Along with the improvement of the pursuit of the mahogany furniture by people, more and more people begin to consume the imitation mahogany furniture, and the higher cost performance and the good imitation appearance meet the requirements of people. But most of the prior simulated redwood technologies lack the sense of reality. The following technologies are available for imitation treatment: (1) the paulownia wood imitation redwood dyeing technology is to dye a veneer for furniture veneering, wherein the veneer is dyed by using 1.5% of NaCl by mass, 0.5% of dye by mass, 2% of acetic acid by mass and 0.1% of penetrant by mass at the temperature of 90 ℃ for 4 hours. The dyeing color of the method is uneven and not firm, and only one layer of the surface is not real enough; (2) the cyclobalanopsis glauca imitation redwood processing technology is to soak cyclobalanopsis glauca produced in the south of Yangtze river basin in hot water at the temperature of 75 ℃, dry for 4 days and conventionally, and the cyclobalanopsis glauca imitation redwood can be used as an imitation redwood material for furniture. The method only solves the problems that the texture and the density of the wood are close to those of the rosewood, and the furniture color needs to be coated with rosewood color paint, so that the furniture color is not real enough; (3) the birch painting imitation redwood technology is to paint imitation redwood paint on birch products, wherein the paint is mainly black, red and slightly golden yellow. The method is not realistic enough. In addition, the above-mentioned several treatment methods are all to treat the existing wood of other varieties, and although the wood is a renewable resource, the excessive felling will cause the damage of the environment, and the limitation is still needed.
Compared with wood, bamboo has the characteristics of fast growth and high Kovar rate. In order to improve the strength and the usability of the bamboo, people produce a recombined bamboo material, namely heavy bamboo, which is a new bamboo material formed by reorganizing and strengthening the bamboo, has multiple characteristics similar to those of common wood, and can be used for replacing the common wood. The existing people treat the recombined bamboo wood by the simulated redwood process to produce high-grade furniture, but the problems of poor simulation effect, lack of reality and the like of common wood exist.
Disclosure of Invention
The invention aims to provide a method for producing high-grade furniture by using a rosewood-imitating process aiming at the existing problems.
The invention is realized by the following technical scheme:
a method for producing high-grade furniture by a rosewood-imitating process comprises the following steps:
(1) bamboo pretreatment:
cleaning the bamboo with clear water, drying the bamboo in the air, and then sawing the bamboo by using a sawing machine for later use;
(2) preparing bamboo bundles:
putting the bamboos treated in the step (1) into a bamboo bundle machine, and untwining the bamboos by using the bamboo bundle machine to obtain bamboo bundles for later use;
(3) carbonizing treatment:
putting the bamboo bundles obtained in the step (2) into a carbonizing machine for carbonizing treatment, and taking out for later use after the carbonization degree is controlled to be 20-35%;
(4) gum dipping treatment:
putting the bamboo bundles carbonized in the step (3) into an adhesive for gum dipping treatment, taking out after the gum dipping treatment, putting the bamboo bundles into a drying oven for drying treatment for 40-50 min, and then keeping for later use; the adhesive is composed of the following substances in parts by weight: 45-50 parts of phenolic resin, 20-25 parts of urea-formaldehyde resin, 2-4 parts of composite pigment, 3-6 parts of sodium dodecyl benzene sulfonate, 2-5 parts of sodium pyrophosphate, 6-10 parts of ethyl acetate, 0.1-0.3 part of stabilizer, 1-3 parts of thickener and 0.1-0.2 part of defoaming agent;
(5) quantitatively paving:
conveying the bamboo bundles treated in the step (4) into a paving machine for quantitative paving for later use;
(6) hot pressing treatment:
carrying out hot pressing treatment on the bamboo bundles paved in the step (5), and taking out the bamboo bundles to obtain a hot pressing part for later use;
(7) quenching and tempering:
putting the hot-pressed part obtained in the step (6) into a constant temperature box, controlling the temperature in the constant temperature box to be 55-60 ℃ and the relative humidity to be 60-70%, and taking out the hot-pressed part after heat preservation and thermal refining for 2-4 hours to obtain a finished plate for later use;
(8) processing a finished plate:
and (5) processing the finished board obtained in the step (7) into furniture according to the existing process.
Further, the number of the segments of the bamboo obtained by sawing the bamboo at one time by the sawing machine in the step (1) is more than two segments.
Further, the temperature in the carbonizer is controlled to be 180-195 ℃ during the carbonization treatment in the step (3).
Further, the temperature in the drying oven is controlled to be 80-85 ℃ during the drying treatment in the step (4).
Further, the preparation method of the composite pigment in the adhesive in the step (4) specifically comprises the following steps:
a. firstly, putting cellulose into a reaction kettle, then adding benzimidazole accounting for 18-22% of the total mass of the cellulose, 5, 6-diaminobenzimidazolone accounting for 7-11% of the total mass of the cellulose and acetone accounting for 280-320%, then heating to keep the temperature of the reaction kettle at 47-53 ℃, and continuously stirring at the rotating speed of 740-780 rpm for reaction for 1-1.5 hours;
