    • PROBLEM TO BE SOLVED: To provide a non-swelling mica powdery material without having creaking or rough feeling, having a good sliding property and a very good use feeling.
      SOLUTION: The surface-treated non-swelling synthetic mica powdery material is characterized by surface-treating a non-swelling synthetic mica powder material with an ammonium cationic surfactant, and having ≤0.25 dynamic frictional coefficient and ≥120° contact angle with water. After heat-treating the non-swelling synthetic mica powdery material at 600-1,350°C, the surface-treated material is obtained by bringing the material into contact with the ammonium cationic surfactant in an aqueous solvent. By heat-treating before the surface-treatment, the non-swelling synthetic mica powdery material having a very high water repellency and use feeling is obtained. By using the ammonium cationic surfactant and a higher fatty acid together, the water repellency and use feeling are further improved. It is suitable to use 0.1-5 mass% ammonium cationic surfactant and 0.1-5 mass% higher fatty acid.

    • 要解决的问题:提供一种不溶胀的云母粉状材料,而不会产生吱吱或粗糙的感觉,具有良好的滑动性和非常好的使用感。 解决方案:表面处理的非溶胀合成云母粉末材料的特征在于用铵阳离子表面活性剂对不溶胀的合成云母粉材料进行表面处理,并具有≤0.25动摩擦系数和≥120°接触角 水。 在600-1,350℃热处理非膨胀性合成云母粉末材料之后,通过在水性溶剂中使材料与铵阳离子表面活性剂接触来获得表面处理材料。 通过在表面处理前进行热处理,可获得具有非常高的防水性和使用感的非溶胀合成云母粉状材料。 通过使用铵阳离子表面活性剂和高级脂肪酸,可以进一步提高防水性和使用感。 适合使用0.1〜5质量%铵阳离子表面活性剂和0.1〜5质量%的高级脂肪酸。 版权所有(C)2006,JPO&NCIPI
