Claims (1)
전항에 설명한 바와 같이 250-300매쉬 범위의 목질 분말을 진공건조실에서 200℃범위를 열건조시킨 후 여기에 실리콘, 다비콘, P.P.G, M.D.I를 같은 비로 조성하고 여기에 소망의 안료를 약간 첨가한 폴리우레탄수지 중합체와 상기한 목분과의 비를 1 : 1로 배합하여 소망의 무늬가 있는 목형에 넣어 섭시 70도 이상의 열에 발포처리하므로서 성형물의 표면에 목형의 조성된 자연무늬와 같은 무늬가 조성되게 함을 특징으로 한 목분을 주재로한 폴리우레탄수지 판재 제법.As described in the preceding paragraph, the wood powder in the 250-300 mesh range was heat-dried at 200 ° C in a vacuum drying chamber, and then polysilicon was added in the same ratio with silicon, dabicon, PPG and MDI, and the desired pigment was added thereto. The ratio of the urethane resin polymer and the above-mentioned wood powder is mixed at a ratio of 1: 1 in a wooden pattern with a desired pattern and foamed at a temperature of 70 degrees or higher so that the surface of the molding has a natural pattern similar to that of the wooden composition. Polyurethane resin plate manufacturing method mainly on wood powder characterized by the above-mentioned.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
