摘要

A manufacturing method of a building plate material is provided to present various colors and to steadily maintain the color by hardening at a heat processing furnace. A manufacturing method of a building plate material comprises followings. A basalt lap(5) is formed as the desiring thickness in a basalt lap willowing device. The basalt lap spraying the cement and water is compressed in the room temperature by a press(6) to reduce the thickness The laminated basalt lap is heated at 300~400‹C while adding the taping force by a compression hot plate(7).
