The production process for resin roofing tiles is a continuous one, involving steps such as batching, calendering, lamination, and molding; the process parameters for each step directly affect the tiles’ weather resistance and service life. For the batching process, a high-speed mixer is used to stir the mixture at 110–130°C for 8–10 minutes to ensure uniformity; uneven mixing can lead to color variations or brittleness. During the calendering process, the mixture is pressed into a 0.5–1.2-millimeter-thick film, which is then coated...
