本文介绍轻质发泡外装饰材料及其制造方法。 本发明者进行反复研究后发现,按粘土40～10份(重量份,下同)、长石60～90份、金刚砂少于1份的比例混合、成形,并以1200～1300℃烧成的轻质制品,具有独立、封闭气孔,其吸水率几乎为零。 本装饰材料所用的原料中,粘土为非发泡性粘土;长石无特别限定,各种长石均可使用;金刚砂要使用粒径在10μm以下的细粉末。 粘土与长石的配比如上述,长石如少于60 This article describes lightweight foam outer trim materials and their manufacturing methods. After repeated investigations, the inventor found that 40 to 10 parts by weight of clay, 60 to 90 parts of feldspar, and less than 1 part of carborundum were mixed and shaped, and fired at 1200 to 1300°C. Lightweight products, with independent, closed pores, have a water absorption of almost zero. Among the raw materials used in the present decorative material, clay is a non-foaming clay; feldspar is not particularly limited, and various feldspars can be used; fine particles having a particle size of 10 μm or less are used for the corundum. Clay with feldspar, for example, above, feldspar less than 60
