    • PURPOSE: A manufacturing method of a hydrophobic inorganic oxide is provided to improve the dispersity of an inorganic oxide in an organic composite by hydrophobizing the surface of a hydrophilic inorganic oxide, and to reduce modifying time and process time. CONSTITUTION: A manufacturing method of a hydrophobic inorganic oxide comprises a step of coating the surface of an inorganic oxide with a silane coupling agent; and a step of irradiating the inorganic oxide with 100-1,200 MHz microwaves. The coating step is conducted by an impregnation method, a spray method, or a ball-mill method. The silane coupling agent is represented by chemical formula 1. In the chemical formula 1, R^1, R^2, and R^3 are the same or different from each other, and each one is a C1-5 alkyl group; and R^4 is a C1-18 linear or branched alkyl group.
    • 目的:提供疏水性无机氧化物的制造方法,通过使亲水性无机氧化物的表面疏水化,提高无机氧化物在有机复合体中的分散性,缩短修饰时间和处理时间。 构成:疏水性无机氧化物的制造方法包括用硅烷偶联剂涂布无机氧化物的表面的工序; 以及用100-1,200MHz的微波照射无机氧化物的步骤。 涂布步骤通过浸渍法,喷雾法或球磨法进行。 硅烷偶联剂由化学式1表示。在化学式1中,R 1,R 2和R 3彼此相同或不同,并且各自为C 1-5烷基; R 4是C 1-18直链或支链烷基。
