た木質様発泡板の開示に係るものである。[Detailed Description of the Invention] [Field of Industrial Application] This invention uses an organic material such as wood flour or wood-based powder as the main raw material and integrally molds it with vinyl chloride resin to improve the characteristics of wood. In order to obtain a synthetic resin board containing a polyvinyl chloride resin, the particles of the synthetic resin board are heated and foamed to closely communicate with each other through a film of molded vinyl chloride resin, in order to strengthen the adhesion between the particles. The present invention relates to the disclosure of a wood-like foamed board whose properties in a molded board are as close as possible to those of pure wood by minimizing the amount of material necessary.

This invention was devised especially in view of the disadvantages in the prior art, and like wood,
Wood flour or wood-based powder for the purpose of providing a lightweight wood-like foam board that can be cut, nailed, and printed, has a touch feeling similar to wood, and has heat insulation, sound insulation properties, and water resistance properties. 20 to 40 parts by weight of vinyl chloride, toluene per 100 parts by weight
30 parts by weight and 5 to 10 parts by weight of azobisisobutyronitrile were mixed together, then put into a mold.95
To provide a wood-like foam board formed by foaming at ℃ to 100℃.

Hereinafter, a typical embodiment of the wood-like foam board according to the present invention will be described. 20 to 40 parts by weight, ideally 30 parts by weight of vinyl chloride resin, which is a resin material whose mechanical properties such as tensile strength are relatively unlikely to be damaged, 30 parts by weight of the solvent toluene, and the blowing agent azobisisobutyro. This is a wood-like foamed board obtained by mixing 5 to 10 parts by weight, ideally 8 parts by weight, of nitrile, thoroughly kneading the mixture, placing it in a mold, and foaming it at 95 to 100°C.

吸湿性が上昇し又表面に「荒れ」が見られた。 The characteristics of the wood-like foamed board formed through such heating and foaming differ depending on the blending ratio of vinyl chloride resin, and if the blending ratio of vinyl chloride resin exceeds 40 parts by weight, the impact resistance properties will change. However, it has a synthetic resin-like appearance and a poor surface finish as a wood-like molded product, and if the amount is less than 20 parts by weight, its impact resistance is poor and its hygroscopicity increases. "Roughness" was observed on the surface.
