(Industrial Application Field) The present invention relates to a method for producing decorative plywood with excellent crack resistance by thermocompression bonding a base material and a surface agent impregnated with a thermosetting resin using an adhesive. (Prior Art and its Problems) Decorative plywood is manufactured by applying an adhesive to a wooden base material and thermocompressing a surface material impregnated with a thermosetting resin onto the top surface. Adhesives that normally bond base materials and surface materials are often based on thermosetting resins, and when adhesives based on thermosetting resins are used, the adhesive hardens due to the heat during thermocompression bonding. During this time, the viscosity of the adhesive decreases significantly. Moreover, since the resin is pressed at a predetermined pressure during thermosetting, if the viscosity decreases, it will be absorbed into the conduit of the base material or flow out from the surface of the base material before thermosetting. Therefore, an uneven adhesive layer is formed between the base material and the surface material, and sufficient adhesion between the base material and the surface material cannot be obtained. Moreover, the expansion and contraction of wood due to moisture absorption and dehumidification causes cracks in the surface material itself.
For this reason, various thixotropic agents and fillers have been added to increase the viscosity of the adhesive to suppress the decrease in viscosity to some extent, but this eliminates the formation of uneven layers due to adhesive leakage under conditions of thermocompression bonding. Moreover, even if the coating amount was increased, a uniform adhesive layer could not be formed. As a result, poor adhesion and cracks still occur. (Means for Solving the Problems) In the present invention, the adhesive layer is formed of two layers: a water-based vinyl urethane adhesive and an adhesive made by adding an organic peroxide and a curing accelerator to an unsaturated polyester resin. , a uniform adhesive layer is formed between the base material and the surface material. (Operations for Solving Problems) The manufacturing method of the present invention forms a two-layer adhesive layer interposed between a base material and a surface material, and constitutes a uniform adhesive layer. In other words, the lower layer adhesive applied to the surface of the base material has the adhesiveness and viscoelasticity of a water-based vinyl urethane adhesive, while the upper layer unsaturated polyester resin has an organic peroxide and a curing accelerator added to it. The adhesive formed by this exhibits a predetermined adhesive property during thermocompression bonding. Therefore, the presence of the water-based vinyl urethane adhesive prevents the adhesive, which is made by adding an organic peroxide and a curing accelerator to an unsaturated polyester resin, from entering or flowing out into conduits, etc., and forms a uniform adhesive layer as a whole. It is something that will be done. (Example) First, the surface material is impregnated with resin, so-called WPC treatment.
The resin liquid used in WPC processing is made by adding an organic peroxide and a curing accelerator to an unsaturated polyester resin. That is, the resin liquid is injected into the surface agent under a predetermined pressure, and blowing and draining are performed. On the other hand, a water-based vinyl urethane adhesive is applied to the surface of the base material to be bonded and dried. The water-based vinyl urethane adhesive is, for example, a water-based adhesive containing polyvinyl alcohol to which a polyisocyanate compound is added and crosslinked through urethane bonds. Examples of emulsion latexes used as water-based adhesives include vinyl acetate, ethylene vinyl acetate/acrylic copolymer, styrene butadiene/acrylonitrile butadiene, methyl methacrylate, vinyl chloride/vinyl acetate, and the like. Also usable are amino condensation resins such as urea resins, cellulose resins such as methyl cellulose, and the like. As the polyisocyanate crosslinking agent, phenylmethane polyisocyanate, tolylene diisocyanate, etc. can be used. After the aqueous vinyl urethane adhesive described above is applied to a predetermined thickness, it is dried, and an adhesive prepared by adding an organic peroxide and a curing accelerator to an unsaturated polyester resin is applied to a predetermined thickness. Next, the surface material described above is placed on the upper surface of the adhesive layer and bonded to the base material by thermocompression. During such thermocompression bonding, the water-based vinyl urethane adhesive is placed on the bottom layer,
Since the adhesive layer made of unsaturated polyester resin with organic peroxide and curing accelerator is formed on the upper layer, the adhesive on the upper layer does not flow into the conduit of the base material, nor does it leak out. do not have. The surface material is then bonded to the substrate by means of a uniform adhesive layer. As a result of the formation of a uniform adhesive layer in this manner, no expansion or absorption occurs due to moisture absorption or desorption of the wood, and therefore no cracks or the like occur in the surface material itself. The combination of the organic peroxide and curing accelerator added to the adhesive based on the unsaturated polyester resin is not particularly limited, and examples include ketone peroxide, hydroperoxide and metal soap (e.g. cobalt naphthenate, vanadyl octoate) or ketone peroxide and
grade amines (for example, dimethylaniline, N.n-diethylaniline), etc. Further, the thermosetting resin liquid with which the surface material is impregnated is not particularly limited, and unsaturated polyester resin, melamine resin, dial phthalate resin, phenyl resin, etc. can be used. Next, Examples and Comparative Examples according to the present invention will be shown. Example 1 A surface material was immersed in a resin solution containing unsaturated polyester as the main ingredient (the blending ratio is shown in Table 1).
Impregnate under reduced pressure of 20 mHg. On the other hand, the water-based vinyl urethane adhesive shown in Table 2 was applied to the lauan plywood base material, and then an adhesive based on unsaturated polyester resin (same proportion as shown in Table 1) was applied at 100%
g/m 2 and left to stand for 5 hours at 20°C, the surface materials were overlaid and applied at 120°C and 6 kg/cm 2 .
Heat compression bonding was performed for 15 minutes. The decorative plywood obtained as described above had a uniform adhesive layer, and when the decorative plywood was subjected to a plane peel test, the base material broke, indicating its high adhesiveness. In addition, this decorative plywood was subjected to the cold and heat cycle B test stipulated in the Ministry of Agriculture, Forestry and Forestry Notification No. 1650 of 1972, and it was tested at 80°C for 2 hours, at -20°C.
No cracks occurred even after repeating the treatment for 2 hours at ℃ twice. Comparative Example 1 110 parts by weight of polyester resin (Orestar RP1033 manufactured by Mitsui Toatsu), 5 parts by weight of calcium carbonate,
An adhesive containing 5 parts by weight of Aerosil and 2 parts by weight of benzol peroxide was applied to lauan plywood at a rate of 200 g/m 2 , and the same surface material used in the example was overlaid. / cm2 under conditions of 15
It was heat-pressed for a minute. The adhesive layer of the resulting decorative plywood was not uniform, and
When a test was conducted, cracks occurred in the surface material after one cycle of treatment at 8°C for 2 hours and -20°C for 2 hours. Comparative Example 2 The adhesive based on the unsaturated polyester resin used in the example (same proportion as in Table 1) was applied as a thermocompression adhesive to lauan plywood at a rate of 200 g/m 2 . Layer the same surface material as the one used and heat it at 120℃ and 6Kg/ cm2 .
Heat compression bonding was performed for a minute. Air bubbles were generated in the adhesive layer of the obtained decorative plywood, and the adhesive layer was non-uniform. When this decorative plywood was subjected to a repeated cold and heat test, cracks occurred in the surface material after only one cycle of treatment at 80°C for 2 hours and -20°C for 2 hours. (Effects) As explained in detail based on the above examples,
According to the present invention, a water-based vinyl urethane adhesive is applied to a base material in advance, and an adhesive made of an unsaturated polyester resin to which an organic peroxide and a curing accelerator are added is applied onto the adhesive. Since the surface material and the surface material are bonded under heat, it is possible to obtain decorative plywood with excellent adhesion and crack resistance due to the uniform adhesive layer.
