堆積養生に一昼夜を要する欠点がある。However, in this case, the surface condition of the base material must be inspected and sorted as a step before base material pretreatment, and there is a drawback that sealing and polishing processes are required after sorting. When the moisture content is absorbed by the base material side, the base material itself swells and the pretreated surface condition becomes rough, and the thickness of the adhesive film at the time of application decreases due to the moisture content. In addition, solvent-based adhesives have the disadvantage of being thin and easily projecting the surface condition of the base material onto the PVC sheet surface.Furthermore, solvent-based adhesives have the disadvantage of causing swelling and deterioration of the base material due to the solvent contained in it being in contact with the base material for a long time. In addition, there is a drawback that the residual solvent may cause the vinyl chloride sheet to swell after being laminated, thereby impairing its appearance quality. As described above, when applying the adhesive, the film thickness becomes thinner due to volatilization and absorption of the solvent. moreover,
In addition, this product has the disadvantage that it requires a whole day and night for curing after laminating the vinyl chloride sheet.

である。As described above, such lamination means require a pretreatment process, which requires a large amount of man-hours and costs, and although the adhesive itself has satisfactory adhesive strength, the thickness of the adhesive layer (wall thickness) It does not go so far as to cover the defects on the surface of the base material, and is therefore unsuitable for laminating decorative vinyl chloride sheets whose surfaces are nearly perfectly flat and glossy.

表面の欠点を充填ないし埋没させる。This invention provides a composite cosmetic material that eliminates the above-mentioned drawbacks of the conventional materials. A two-component urethane with no thickening agent, consisting of a base agent mainly composed of hydrogen compounds (e.g. polyesters, polyethers, ricinoleate in castor oil) and a curing agent mainly composed of polyisocyanate. By utilizing the foaming property of the adhesive during the curing reaction, a vinyl chloride sheet is overlaid on the surface of a porous and absorbent base material. Further, to explain in detail with reference to the embodiments shown in the figures, first, as shown in FIG. dents such as 3,
A base material 7 made of wood or the like that has defects such as unevenness 4 due to entangled fibers and fuzzed fibers 5 is directly coated on its surface without any pre-treatment (fabric finishing) as described above. A two-component mixed urethane adhesive 6 is applied, which is an adhesive type and has foaming properties during the curing reaction. As the curing reaction progresses, the six layers of adhesive applied expand their volume due to foaming, resulting in the voids 1, grooves 2, depressions 3, unevenness 4, and fluff as shown in FIG. The defects on the surface of the base material 7 in No. 5 are filled or buried.

ることができるものである。As described above, the present invention uses a two-component mixed urethane adhesive that is non-drying agent type and has foaming properties during the curing reaction, thereby increasing the apparent volume of the adhesive layer due to foaming. This is a pre-treatment step for the surface of porous and hygroscopic substrates (e.g., wood-based substrates) by filling or burying defects such as voids, recesses, and fuzzed fibers on the surface of the substrate due to expansion (fabric finishing). In addition, the surface of the vinyl chloride sheets can be uniformly flattened by using the elasticity of the foam layer of the adhesive before curing and the destruction or deformation of the foam cells due to external pressure. can be obtained with a short deposition and curing time, and furthermore, this hardened adhesive layer prevents the surface of the vinyl chloride sheet from being affected by the hygroscopic swelling of the base material when exposed to high temperature and high humidity conditions. It is possible to provide a composite decorative material with features such as:
