Description

Technical Field

[0001] The present invention relates to the technical field of silicone leather, and in particular to a processing device and method for soft dust-proof silicone leather products for furniture. Background Art

[0002] Silicone leather is a new type of environmentally friendly leather made from silicone. This new material is combined with microfibers, non-woven fabrics and other substrates for processing and preparation. It is suitable for a variety of industrial applications. This leather adopts solvent-free technology to coat silicone on various substrates and bond them to make silicone leather. To meet the needs of silicone leather, the silicone raw materials are rationally proportioned to achieve the soft and dust-proof properties of silicone leather. Existing soft and dust-proof silicone leather products often require the use of coating equipment to coat the silicone raw materials on the substrate during the processing. During the coating process, due to the presence of bubbles in the silicone raw materials, the silicone leather is prone to bubbles after heating and curing, which in turn affects the smoothness of the leather. In addition, when the silicone raw materials are coated, the edges of the substrate are often not evenly coated, resulting in poor quality of the molded silicone leather. Summary of the Invention
