砂状外墙彩色涂料的基料是苯乙烯—丙烯酸树脂乳液。砂状外墙涂料在日本分为AB两类;A类以天然石英砂为骨料,并添加氧化铁系或酞菁系等耐久颜料而制成;B类是以天然石英砂或人工烧成的彩色砂子或陶瓷粒等为骨科,不另加颜料(利用砂粒本身的颜色)便可制成。由苯乙烯—丙烯酸乳液为基料制成的建筑涂料,是日美等工业发达国家目前涂料市场上用量最高的一种,而且,日本仍旧每年以8％的速度在增长,但
The base material for the sand exterior color paint is a styrene-acrylic resin emulsion. Sand-like exterior wall coatings are divided into two types of AB in Japan; Class A is made of natural quartz sand and is made of durable pigments such as iron oxides or phthalocyanine. Type B is made of natural quartz sand or artificially fired. The colored sand or ceramic grain is orthopedic and can be made without additional pigment (using the color of the sand itself). Architectural coatings made from styrene-acrylic emulsions are the highest in the paint market in Japan, the United States, and other developed countries. Moreover, Japan is still growing at an annual rate of 8%, but
