以下、図面を参照しつつ工程を追っ[Industrial Application Field] This invention relates to a resin treatment method for wood materials, in which a solid epoxy @ fat and a liquid epoxy resin are combined on the surface of the wood material. By applying the resin to the surface of the wood and subjecting it to heat and pressure treatment, a smooth and uniform resin film is formed on the surface of the wood, and the resin also penetrates into the wood and hardens to strengthen the wood. . [Conventional technology] Conventional resin treatment methods for wood materials include the WPC method, in which wood materials are impregnated with a resin such as unsaturated μ polyester resin by vacuum and pressure treatment, and hardened under heat and pressure; The overlay paper method involves impregnating a resin with resin, drying it, coating it on a wood material, and curing it under heat. Or, do you use the overlay paper method, in which a resin is impregnated with resin, dried, and then coated on a wood material and cured under heat? Or is there a method of fusing powdered epoxy resin, etc., to nonwoven fabric or paper? A powder at IIh film method is known, in which the powder is compressed and cured by heat and pressure together with a wood material. [Problems to be Solved by the Invention] However, these resin treatment methods have the following problems, and a solution to these problems has been desired. First, in the WPO method, resin is impregnated by pressure reduction and pressure treatment, so the process is complicated and the equipment is large-scale, increasing manufacturing costs, and a resin film is formed on the surface of the resulting treated wood. No, a separate top coat is required. In addition, with the overlay paper method and powder resin film method, the flow of the resin is poor, and when using wood materials with large conduits, "floating" or "
Cannot be used due to "whitening" phenomenon. Since non-woven fabric or paper is used, this remains in the resin film, reducing the transparency of the resin layer and increasing the film thickness (100 μm).
above), the flexibility is poor. [Means for solving the problem] Therefore, in this invention, a solid epoxy resin and a liquid epoxy resin are combined, applied to the surface of a wooden material by means such as coating or spraying, and then subjected to heat and pressure treatment. , to solve the above problems. Below, follow the process while referring to the drawings.

On the surface of this wood material 10, first, a liquid epoxy resin layer 2 is provided, as shown in FIG. This liquid epoxy resin layer 2 is obtained by applying liquid epoxy resin to a basis weight of about 20 to 200 Jil/m using a coating means such as a roll coater. The liquid epoxy resin used here is a liquid epoxy resin that is liquid at room temperature (20 to 25°C) and a predetermined curing agent added thereto, such as the Bis7-1-norm type. This applies to epoxy resins that have an epoxy equivalent of about 225 or less. In addition, epoxy resins that are liquid at room temperature, such as Novo2-type epoxy resin, glycidyl ester/L/type epoxy resin, and brominated epoxy resin, can also be used. Next, powder epoxy resin #3 is provided on this liquid epoxy resin layer 2 as shown in FIG. This powder epoxy resin layer 3 is made by adding a curing agent in a predetermined common ratio to epoxy *11* that is solid at room temperature, and then forming a mixture with a particle size of 50 to 150 μTr.
Powdered epoxy resin that has been crushed to about L size is applied by means such as electrostatic coating or spraying.
It can be obtained by dispersing it in small amounts. The solid epoxy resin used here is an epoxy resin that is solid at room temperature (20 to 25°C), and for example, Suphenol A type epoxy resin has an epoxy equivalent of about 225 or more,
Generally, those having a molecular weight of 450 or higher are applicable, and other types of novolac type epoxy resin, glycidyl ester type epoxy resin, brominated epoxy resin, etc. that are solid at room temperature can be used. Further, an extender pigment such as calcium carbonate, a coloring agent, and an antifoaming agent may be added to the powdered epoxy resin as necessary. Next, as shown in FIG. 3, the wooden material 1 provided with the liquid epoxy resin layer 2 and the powder epoxy resin M3 is
Insert with a sheet of release film 4.4, hot press 5.5
Heat and pressure treatment is performed. Jlli! As the mold film 4, a heat-resistant, non-adhesive fluororesin film having a thickness of about 15 to 50 μm is suitable. [
The temperature is usually 130 to 150°C, the time is 7 to 20 minutes, and the pressure is the same or lower than that applied to laminated sheets of plywood, etc., although the conditions may be determined as appropriate. Due to the heat and pressure treatment, the liquid epoxy resin rapidly reduces its viscosity, becomes highly fluid, and penetrates into the wood.At the same time, the moisture, air, etc. in the wood become bubbles. The liquid epoxy resin moves outward through the highly fluidized liquid epoxy resin and dissipates to the outside. In addition, the homogeneous epoxy resin also melts, but since it has a high melt viscosity, it flows into concavities such as conduits on the surface of the wood material 1 and stays on the surface, where it mixes with the liquid epoxy resin leaking onto the surface. As the heating cycle continues, both epoxy resins begin to crosslink and solidify. Then, as shown in Figure 4, 11! Film for mold 4.
By peeling 4, the desired resin-treated wood material 6 can be obtained. The interior of the thus obtained resin-treated wood material 6 is hardened and strengthened with epoxy resin, and the exclusive portion on the surface is also filled with epoxy resin, and a resin film 7 is formed on the surface. Note that if a film is used as the release film 4, the a(Jjill film 7 will have a @tpx finish, and if a film with a tabular pattern is used, a glossy finish will be obtained. According to the epoxy resin impregnation and curing can be done simultaneously by heat and pressure treatment, the number of steps is reduced, the work is simplified, and only a small amount of equipment is required, and the overall flow of epoxy resin is improved. (70-)
The resin flows sufficiently into concave areas such as large conduits, and a smooth resin film 7 made of hardened epoxy resin is formed on the surface of the wooden material, making it possible to eliminate the need for a top coat. Furthermore, since a resin carrier such as nonwoven fabric or paper is not used, the resin film 7 becomes a coating film with good transparency, and the film thickness can be made correspondingly thinner, so that a resin treated material 6 with good flexibility is obtained. In addition, since powder epoxy resin and liquid epoxy resin are combined, powder epoxy resin alone does not have the adhesion to the wood material, so it flows during work, making handling difficult. There is no problem with the liquid epoxy side fat, and there are no problems such as the liquid epoxy side fat immediately becoming fluidized and flowing out during heat and pressure treatment. [Other Specific Examples] This shows another example of the resin treatment method. In this treatment method, a paste-like mixture of powdered epoxy resin and liquid epoxy resin in a predetermined ratio is mixed with a roll comb or a doctor blade. A mixed epoxy resin layer 8 is applied to the surface of the wood material 1 by means such as
, and then sandwiched between flood-relief films 4.4 and subjected to heat-pressure treatment. This treatment method requires only one epoxy resin application step, improving work efficiency. [Example 1] As a wood material, a 0.2 am thick American fall nut decorative veneer was beaten with a non-woven fabric. On the surface of this veneer, apply an 11ti layer of liquid epoxy resin.
Epikote 828 (epoxy K190, liquid, made by Yuka Shell) 100 hardening agent 2-ethyl, nt-4- in the lid part
1 mixture of methyl-imidazo-/L/3 parts by weight
00 #/m was applied. Then, on top of this, Epikote 1004 (epoxy resin [90
0, solid, oily shell [) 100 hardening agent in the lid part 2-
A powdered epoxy resin containing 3 parts by weight of ethyl-4-methyl-imidazo-/I/1 and pulverized in a ball mill to a mesh pass of 200. ! 9/ Go was defeated. Thickness 25μ
It was inserted with a 1llIi type film of polyfluorinated vinyl/l/m film and subjected to hot pressure treatment at 130° C. for 10 minutes using a hot press. The obtained resin-treated veneer is resin-reinforced and has a transparent surface with a thickness of about 100 μm and a smooth surface with good ml+m
PIA is formed and finished with American walnut decorative material with a beautiful finish. [Example 2] As a wood material, an American fall nut decorative veneer with a thickness of 0.2 y<rtt was prepared by sprinkling it into a non-woven state. Six times on this veneer, add a layer of mixed epoxy resin,
Three parts of 2-1 ethyl-4-methyl-imidazole were blended with 100 parts of Picote 828, pulverized to 100 mesh passes, mixed and stirred, and a paste-like mixture was applied to 300I/TrX. This was subjected to heat and pressure treatment in the same manner as in Example 1 to obtain a wood-treated veneer. The resulting resin-treated American fall nut veneer had a similar finish. [Effects of the Invention] As explained above, the surface of the essential material of the present invention is treated with a solid epoxy resin and a liquid epoxy resin, and then subjected to heat and pressure treatment. Epoxy I (impregnating with fat and curing can be done all at once by heat-pressure treatment, simplifying manufacturing work and requiring simple manufacturing equipment. In addition, the epoxy resin as a whole has high fluidity, The resin flows sufficiently into concave portions such as conduit portions, and a smooth and uniform resin film is formed on the surface in place of a top coat, and can be used as a product as a decorative material.
