The objects, features, and details of the present invention should be made clear. ^The situation and the advantages are as follows. [Embodiment] The present inventors focused on the effective use of the acacia tree bark discarded by the Acacia Tree Plantation Business. However, it has been found that by adding a powder of Acacia bark, an inorganic filler such as carbon_, and a paste prepared by water to the aqueous solution of the A (4) (iv) resin, the viscosity increase after the preparation can be suppressed. Further, since the content of the paste liquid is larger than that of the conventional laminate composition for the laminate, the problem of dryness can be suppressed, and the bursting phenomenon at the time of producing the plywood can be suppressed. In addition, the present inventors have admitted that in the sanitary industry use site of the paste liquid, there is a veneer having a high water content (for example, a water content of 10% by mass to an nf amount) which is mixed with the use of the above. It is also possible to maintain sufficient adhesion between the veneers and to suppress the problem of dry wine, and to suppress the composition of the paste liquid required for the bursting phenomenon during the manufacture of the plywood. Further, it has been found that the plywood produced by using the mash can suppress recursion or distortion. Then, the present invention has been completed on the basis of such knowledge. Hereinafter, embodiments of the present invention will be described. However, the present invention is not limited to this embodiment. In the adhesive composition for a plywood of the present embodiment, the acacia tree bark powder 15 mass portion and the inorganic portion are added to the mass portion of the resol type phenol resin aqueous solution having a resin content of 40 to 50% by mass. Filling material 25~?接着 The adhesive composition for the plywood prepared by the mass portion and the water of 1 to 50 parts by mass. 201207064 The laminate adhesive composition inhibits an increase in viscosity after preparation as compared with the prior laminate adhesive composition. Further, when a veneer having a normal or low water content is used, even when a veneer having a high water content is used, the bursting phenomenon at the time of manufacturing the ply is suppressed. In addition, the problem of cognac can be suppressed. In addition, the recursion or distortion of the manufactured plywood can be suppressed. Furthermore, it is strict and economical. In addition, the adhesive composition for a plywood of the present embodiment is added to the acacia tree bark powder by using a resinous portion of 40 to 5% by mass of the bismuth (four) type resin aqueous solution 1 〇曰〇 mass portion. 1 〇 quality part, inorganic filler material 50 quality. An adhesive composition for plywood prepared by p and 25 to 50 parts by mass of water. ''' The use of the adhesive composition for the plywood is particularly suitable for use in the use of a veneer having a water content of a relatively low or low (the water content is less than 丄〇 mass%). Further, the adhesive composition for a plywood according to the present embodiment is a resin (10) (4) resin aqueous solution (10) 25 to 70 mass enthalpy and water 1 〇 25 compound having a resin content of 4 G to 5 G% by mass. (4) Plywood adhesive group: using an adhesive composition, especially when using a veneer having a water content of generally or relatively low (the ratio is less than 10% by mass), and further in the case of ^(4) When the high veneer (water content is more than 1% by mass), it is also: Γ: 'The adhesive composition for the plywood, the moisture content is general:: the veneer has a veneer and the relatively high veneer In the case of mixing, it is useful. However, if the moisture content of the veneer is as high as 20% by mass, then 6 201207064 is not only a phenomenon of bursting, but also the hardening of the phenol resin and the adhesion of the plywood. The adverse effect of this embodiment is that the acacia tree bark powder is preferably taken from 1 〇 to 150 μm. The average particle size of the acacia tree bark powder is less than i 〇 m ', which reduces the acacia tree bark powder. When the dispersibility in the composition of the composition exceeds 150 Am, the coating device of the adhesive composition is likely to be clogged. In the present embodiment, it is preferable to further add a polyvinyl alcohol oxime. , can improve the false adhesion of the veneer, or prevent the paste from drying When the amount of polyvinyl alcohol added is less than 1 part by mass, the effectiveness of the addition is lowered, and when it exceeds 3 parts by mass, the economy is lowered. In the present embodiment, the gas phase type cerium oxide is further added. U Berry 4 is preferred. Gas phase cerium oxide has the effect of improving the coating workability of the paste, or inhibiting the effect of the paste liquid dry wine. The addition amount of the gas phase dioxin is not full. Then the effectiveness of the addition is reduced, and if it exceeds 2 mass parts, the economy is lowered. The method for producing a plywood according to the present embodiment is a method for producing a plywood in which the plywood composition for a plywood is applied to a veneer, and a plurality of veneers are superposed, pressurized, and heated. According to the method of the slab of the slab, the method for the splicing of the slab is used to produce an adhesive composition for a plywood having an increased viscosity which is more resistant to the γ after the preparation. In addition, regardless of whether the ratio of the &gt; is a general or low veneer, that is, a veneer with a south moisture content is used, _ each sentence can suppress the bursting phenomenon. In addition, the problem of drying up can be achieved. Recursive or twisting of the plywood produced by the suppression of _. ̄° Further, the manufacturing method of the plywood is excellent in k-type and economical. 201207064 The plywood according to the present embodiment is a plywood produced by the above production method. When the S plate is a veneer having a normal or low water content, even when a veneer having a high water content is used, the bursting phenomenon or the peeling can be suppressed, and a good adhesion can be ensured, and the recursion or distortion can be suppressed. Plywood. Further, in the plywood according to the present embodiment, the adhesive layer is a 40 to 50 mass portion of the cured phenol resin, and includes a plywood of the acacia bark powder 15 mass portion and the inorganic filler 25 to 70 mass portions. The adhesive layer of the plywood is 〇5 to 5% by mass of the hardened phenol resin, and includes 15 parts of acacia bark powder and 25 to 7 parts of inorganic filler. In this way, it is understood that the acacia tree bark powder is added in an amount of 1 to 15 parts by mass, and the inorganic filler is added to the mass portion of the resol type phenol resin aqueous solution having a resin content of 4 〇 to 5 〇 mass%. An adhesive composition for a plywood prepared by a mass portion of 25 to 7 Å and a mass of 1 to 5 Å. The composition of the adhesive layer of the ply is based on the above-mentioned adhesive composition for plywood, and the composition of the base of the water-removing base is cured by a predetermined blending ratio of the resin, the acacia resin powder and the inorganic filler. . In general, in the production of a plywood, if an organic solvent other than water is added to an adhesive composition of a resol type phenol resin, most of the organic solvent will vaporize and evaporate during the production of the ply, so that the working environment is And security has a big problem. Therefore, the conventional practice is that the composition of the adhesive composition other than water used for the production of the plywood is substantially incapable of using a solvent other than water, and there is a direct correlation with the composition of the adhesive layer which is cured in the production of the plywood. Then, if water 10 is not added, the viscosity of the paste is too high when the mass is 8 201207064, and the manufacture of the plywood may be difficult. That is, the adhesive layer after hardening is hardened in a state in which a large amount of the solid portion of the acacia tree bark powder 15 mass portion and the inorganic filler material 25 to the enamel portion is hardened, and the mass is not included in the = segment of the adhesive composition. In the case of water of a part, the viscosity of the paste becomes too large, and it is difficult to apply the adhesive composition to the veneer. Therefore, in other words, the cured adhesive layer is the phenol resin 4. ~5 〇 mass part, package: Acacia tree bark powder 15 mass part, inorganic filler 25~7 〇 mass part of the solid part of the state of hardening, will be the evidence of the adhesive 10, the mass of the water. The term "wearing phenomenon" refers to the fact that in the manufacture of plywood, when the moisture content of the veneer is high or the content of water in the adhesive composition is large, the water vapor generated during pressurization or heating is caused. In the case of decompression, the phenomenon in which the adhesive layer is formed in the adhesive layer to expand the adhesive layer is a phenomenon in which peeling occurs between the veneers. The term "dry cognac" refers to the subsequent application of the veneer to the veneer. When the agent composition is removed from a large amount of water and a phenol resin aqueous solution, even if the veneer coated in this state is overlapped with the uncoated veneer, the transfer of the adhesive agent to the opposite veneer cannot be sufficiently performed, and becomes the next step. In the present embodiment, the adhesive composition for a plywood is more resistant to an increase in viscosity after preparation than the adhesive composition for a plywood of the prior art. In the present embodiment, the adhesive composition for a plywood, when a veneer having a high or low water content is used, even when a veneer having a high water content is used, 01207064 Suppresses the phenomenon of bursting when manufacturing a plywood. This is considered to be excellent in hydrophilicity of the cellulosic material, and the fiber f contained in the bark of the acacia tree in the bark of the acacia tree is used as a water-breaking fixed pressure which is affected by the adsorbed water. Therefore, it is not easy to generate air bubbles. Therefore, even if it is a problem of the adhesive composition for a plywood of the present embodiment, it can be considered that the adhesive is a dry adhesive for the pour of the same age and the same age. In the present embodiment, it is possible to suppress the recursion or the distortion by using the plywood of the above-mentioned plywood pick-on composition, which is contained in the acacia tree bark. The action of the soluble component does not allow the water containing the composition of the splicer to penetrate into the plywood. Further, in the present embodiment, the adhesive composition for plywood is more conventional than the adhesive composition for the plate. A large amount of water is diluted to blend a large amount of inorganic filler, so that the content of the resol phenolic resin per unit equivalent of the adhesive composition becomes relatively small, so the environmental load is small, and The adhesive composition excellent in environmental properties is also an economical excellent adhesive composition. <曱 盼 型 式 式 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂 树脂The aqueous solution of the resol-type phenolic phenol resin which is generally sold as an adhesive agent can be industrially produced without limitation. Such an aqueous solution of a aging-age resin of a aging type is generally a synthesis example of an embodiment as described later. It is shown that the phenol and the aldehyde are mainly produced by heating and reacting under water under a strong condition such as sodium hydroxide. The phenol resin aqueous solution is generally 10, 10,706,064 in an aqueous solvent containing a resin component ( Solid content, non-volatile part) Qin 5 〇 mass%, viscous and strongly alkaline liquid. A method for producing a resol phenol resin aqueous solution, in addition to the above patent documents, for example, also described in Japanese Patent Laid-Open 2 1_15212 nickname bulletin, etc. Since the resol type phenol resin has a self-reactive functional group, it can be directly hardened by heating. The resol phenolic resin itself hardens itself. The resol type phenol resin is hardened by heat to be insoluble and infusible. Therefore, it is preferable to manufacture the s-plate, and to use a resol-type phenol resin which is hardened only by heating, and which is excellent in strength and water. The phenol used in the present embodiment is not particularly limited. Examples thereof include alkyl phenols such as phenol and nonylphenol; aromatic diols such as resorcin and phthalic acid; and bisphenols such as bisphenol A. The aldehyde to be used in the present embodiment may, for example, be formaldehyde, acetal, acetaldehyde or the like. —Polymerization The alkaline reaction catalyst to be used in the present embodiment may, for example, be sodium hydroxide, potassium hydroxide, calcium hydroxide or barium hydroxide. The blending ratio of the phenols to the aldehydes is preferably from the viewpoint that the curing rate of the obtained resol-type phenol resin is increased, and the molar ratio of the (aldehyde/phenol) is preferably 2. Further, the aldehydes produced by the plywood produced are less likely to be produced, and the production environment may be changed from the viewpoint of a good molar ratio of aldehydes/phenols to 3.5 or less. In the present embodiment, in particular, the molar ratio of (aldehyde/phenol): 1. 8-2. 8 is more preferable. Further, the resol-type phenol resin which is used in the present embodiment in which the water repellency is high can provide a resistant adhesive composition. In the present embodiment, one type of the resin may be used alone or in combination of two or more. <Acacia Tree Bark Powder> The acacia tree bark powder which can be used in the present embodiment is not particularly limited. For example, powders such as straight acacia bark, acacia hybrid bark, and acacia wood bark may be mentioned. Among these, it is preferred to use a powder of a straight dried acacia tree. In the bark of Acacia, there is a relatively high content (for example, about 3%) of the outer bark and a relatively low inner bark of a methanol extract (a portion of the polyphenol-containing extract containing methanol). In an embodiment, it is not necessary to separate the outer bark from the inner bark. The tannin containing the acacia tree bark contains f, and according to the knowledge of the present invention, the effect of the present invention is not greatly affected. That is, in the present embodiment, only the powder of the outer bark, the powder of only the inner bark, the mixture of the powder of the outer bark and the powder of the inner bark can be favorably used. Industrially, the straight-dried acacia bark powder with an average particle size of 150" or less is not crushed by the outer bark and the inner bark, and the methanol extract is about (10). From the economic point of view, it is a good one. Acacia tree bark powder The production method is not particularly limited. For example, the method of pulverizing the bark of a progress, using the pulverization center of the ball mill type pulverizer, the average particle diameter of the powder, and the subsequent composition of the bark The viewpoint of coating ± is blocked by a cloth device (for example, a spreader, etc.) -= is better as follows, and further preferably 50% is better than 30. The tree bark powder is more easily dispersed in the adhesive. In the present embodiment, the Acacia tree bark powder can be used in two or more types according to the present embodiment. The tree bark powder has an effect. <Inorganic filler> The inorganic filler used in the present embodiment can be used, for example, calcium carbonate, cerium oxide, diatomaceous earth, kaolin, gypsum, &amp; In the present embodiment, calcium carbonate is preferred from the viewpoint of strength, hardness, and economy of the cured product of the adhesive composition (that is, the adhesive layer after the laminate). The average particle diameter of the inorganic filler is preferably 150/zm or less from the clogging of the coating device (for example, a spreader) for the veneer composition, and is preferably 1 〇0/zm or less. For better, further 50&quot;m or less is preferable, α30&quot;m is better, and 1〇^ is more preferable. Fine powdery inorganic fillers of less than l〇/zm can be easily taken on the market. In view of the fact that the inorganic filler is more preferably dispersed in the adhesive composition, it is preferably 1 # m or more. In the present embodiment, the inorganic filler may be used singly or in combination of two or more. Calcium carbonate is an essential component, but depending on the situation, carbon_ as an essential component can give a better result than in the case of water, in the present embodiment, the use of the aqueous solution of the A-stage age-type resin is 100 mass 较. Adhesive composition phase for laminate For larger amounts of !. 卩 water, deionized water is preferred. The adhesive composition is used in a veneer containing 201207064 water ratio = generally or relatively low (eg less than ίο% by mass, eg etc. In order to suppress the incidence of bursting, the amount of water added is preferably 25 to 5 〇 mass for 1 〇〇 mass portion of the aqueous solution of the 曱 酴 盼 type of resin, and is used for a board having a relatively high 3 ^ ratio (for example) 10% by mass or more, for example, 1 〇 to 17 or 4) is used to suppress the occurrence of bursting, and it is found that the amount of water added is preferably 1 () to 25 parts by mass of the aqueous solution of the first-order acid-age resin. However, it is also possible to use an adhesive composition in which the amount of water is added in an amount of from 1 to 25 parts by mass, and is used for a veneer having a general or relatively low water content. In addition, as long as the amount of water added is 1〇~5. The adhesive composition in the range of the mass portion can be used for a veneer having a low water content or a low rut according to the condition, without limiting the moisture content of the veneer, or can be used for a relatively high moisture content. board. <Action mechanism> The inventors of the present invention added water to a resole type phenol resin aqueous solution having a resin content of 4 〇 to 5 〇 mass%, and adding the acacia tree bark powder to the diluted solution, the degree of the diluted solution slightly increased. The viscosity is suitable for coating, and the hardening speed is still increasing. That is, a paste liquid diluted with water is obtained. However, the Guhai resin, which has a relatively low amount of the paste, is applied to a veneer having a relatively large surface roughness (concavity and convexity) to bond it, and sufficient adhesion cannot be imparted. The present inventors have found that the addition of an inorganic filler to a paste liquid having a relatively low resin content can provide a paste coating amount (35 to 40 g/ft 2 ', that is, 37 to 43 mg/cm 2 ) of a general veneer. Good adhesion is available. Blending ratio

When the moisture content of the early plate is relatively low (for example, less than 1 〇. or 1 ϋ 罝 ,..., it is found that the amount of water added is large, and the addition of acacia tree bark powder is less than the amount of inorganic filler added, and the swelling is suppressed Occurs, and can be passed on a very good receiver, etc., can get good sex, and other aspects of the board when the water content is relatively high (for example, 1 〇 mass% = above) 'found to make the water addition rate is low 'Acacia tree bark powder addition amount: no: the filler material is added in a large amount' to suppress the occurrence of bursting, and can obtain a good 'contact force' and can obtain good performance. The paste liquid prepared in such a blending ratio The properties such as the viscosity of the paste, the viscosity of the paste, the stability of the viscosity of the paste, and the high water resistance and high adhesion of the adhesive composition for the plywood can be sufficiently balanced. Since it is added to the f-order (four) type (four) grease In the case of the aqueous solution, the amount of the three components (Acacia tree bark powder, water, and inorganic filler) which are excellent in I and the life of the moon b is related to each other. Therefore, it is difficult to add the amount of each component and the month of performance b. It is known, but it is known as follows. (Acacia tree bark The blending amount of the final phase is more than 1 part by mass of the aqueous solution of the acacia phenolic resin in an amount of 40 to 50% by mass of the resin component, and the blending amount of the acacia tree bark powder is 1 part by mass or more. The viscosity of the paste liquid is increased to a viscosity suitable for coating. In addition, by making the blending amount of the acacia tree bark powder 10 mass or less, the economics of the paste liquid can be ensured, but the high water content veneer is mixed and used. At the time of 'inhibiting the bursting and trying to improve the force, you can also choose to phase 15 201207064 under the acacia tree bark. - Generally speaking, the blending amount of the tree of the tree of the 1st quality of the phase 1 is increased to 15 mass. The blending amount of the powder is more than 15 f. The economical poorness of the tree bark powder is preferably 2 to 6 mass parts of the aqueous solution of the p-phenolic phenolic resin. (Water blending amount) The aqueous solution of the A_type resin is blended with the acacia bark powder t and can be withered. A larger amount of water is a characteristic of the present invention. For the resin portion, 40% by mass of the aqueous solution of the phenolic phenolic resin _ mass portion, using - When the veneer is made, by making the water The amount of 25 parts by mass or more 'is effective in suppressing the effect of dry wine, reducing the environmental load, improving the economy (IV) effect, etc. On the other hand, when the veneer with high water content is mixed into use, the amount of water is adjusted by In the case of 1 to 25 mass parts, the effect can be maintained. When the amount of water blending is less than 1 mass, the economical efficiency of the object 1 of the present invention cannot be sufficiently exhibited. Further, by adjusting the amount of water to μ The mass Ρ below can avoid a large amount of blending of the inorganic filler. That is, when the blending amount of water to the 100 parts of the resol type phenol resin aqueous solution exceeds 50 mass parts, the paste liquid is coated in a general paste liquid amount. It is difficult to ensure solid damage on the veneer. Then, at this time, a large amount of inorganic filler is blended to ensure solid damage of the veneer, but a large amount of blending of the inorganic filler will impair the workability of the paste, which may easily cause Then the force drops. Further, after the paste liquid is applied, the bonding, pressurization, and heating are performed in a short time, and the adhesion force is likely to be insufficient. In other words, by setting the amount of water to the mass of the phenolic-type sole resin aqueous solution in the mass fraction of 50 parts by mass or less, it is possible to avoid mixing a large amount of inorganic filler, and to maintain the paste coating property, and to obtain sufficient follow-up. force. 201207064 (Adjustment amount of inorganic filler) The appropriate blending amount of the inorganic filler depends on the water content of the veneer and the like, and the blending amount of the acacia tree bark powder is related to the amount of water blended. Then, in the amount of 1 GGf of the aqueous solution of the fourth-order (four) (four) resin, the blending amount of the inorganic filler is 25 parts by mass or more, and the resin content is relatively low, so that the amount of the paste can be applied to the general veneer. , the above effect of good adhesion is obtained. Further, even in the case of a veneer having a high water content, the blending amount of the inorganic filler is $7. The high-profile "heavy" below the mass portion avoids the problem that the adhesion of the dry wine is lowered as described above, and the adhesion of the resin is poor. In order to improve the coating workability of the paste liquid, the high adhesion force is maintained, and the blending amount of the inorganic filler is preferably 6 parts by mass or less. A better blending amount of the inorganic filler to the mass portion of the aqueous solution (10) of the acid step type resin, in the case of a general veneer, it is preferably 25 to 5 〇 mass portion, preferably 30 to 45 mass parts. When the high water content veneer is used in combination, depending on the blending amount of the water and the acacia bark powder, there may be a case where the amount is ～6 〇1, and further, the mass portion is 45 to 55, and the mass portion is preferably π. (Specific Example of a Preferred Formulation) For the above reasons, a specific example of a preferred formulation of the adhesive composition for a plywood of the present embodiment is, for example, a general moisture content of about 8% by mass. Plate, for the resin portion of 4 〇 to 5 〇 mass% of the resol phenolic resin aqueous solution 100 parts of the 'addition average particle size 1 〇 ~ 3 〇 #m methanol extract is about 20% of the Acacia tree bark powder 2 ~ 6 mass parts, average grain size 1 〇 m calcium carbonate 3 〇 〜 4 5 mass parts and water 2 5 ~ 5 〇 mass parts 17 201207064 prepared laminate composition for the laminate. In other aspects, the use contains water When the rate is 10% by mass or more of the veneer of the high water content veneer, the resin is The portion is 4. to 5. mass% of the aqueous solution of the first-order (four)-type resin in the mass%. The mass portion is added with the average particle diameter of the acacia tree bark powder of 3 to 1% by mass fraction of 1% by mole of the 1% alcohol extract. The composition of the composite material (4) prepared by the carbon dioxide dance of the average particle diameter and the mass portion and the water portion of 15 to 25 parts by mass is preferably a specific example: a high water content containing a water content of 1% by mass or more is used. Specific examples of the preferred formulation include those of 5 to 10 parts of acacia bark powder and about 35 parts of carbonic acid. 33 Buyi and water 1540 (correlation formula of the amount of the three components) Morphology, the correlation of the three components to the appropriate amount of the liquid phase _ mass fraction, and the moisture content of the general moisture content of the veneer 1 is approximately the combination of the following blending amounts.

The viscosity increases. For such a resorptive phenolic resin, the viscosity is increased. A powder component such as acacia bark powder or an inorganic filler is added, and the workability of mixing is poor. Therefore, in the present embodiment, the powder component (Acacia tree bark powder, inorganic filler material, PVA 'gas phase cerium oxide, flour, etc.) is mixed in advance, and only the resol type phenol resin is used in the plywood factory. The water and the pre-mixed powder are formed into a paste, which is preferably from the viewpoint of work efficiency.

The other points are the same as in the first embodiment. J-combination (following test) The adhesive composition of Example 20, u, and the same example 19 were treated with a mastic for subsequent testing of the veneer. However, as a result of the subsequent demise, five pieces of veneer that are used to adjust the moisture of the ancient phase wood to 6.5% are used. The following is the following: The average value of the breaking rate of the wood is shown in Table H /. The phenol resin in Example 20 has a large incremental rate, and the dryness is favorable to the economy and economy, although the phenol resin content is relatively small. The power of the dry money and the breaking rate of the wood are excellent. It can be considered that because of the increase in the amount of calcium carbonate, the viscosity-retaining property is still observed in the adhesive layer of the plywood, and no bursting phenomenon (peeling) occurs [Table 10].
