Title:
RESIN COMPOSITION AND METHOD FOR DETERMINING FLAME RETARDANCY OF RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2018/181185
Kind Code:
A1
Abstract:
Provided are: a resin composition which is suitable for use in producing flame-retardant molded articles and which can impart high flame retardancy even when containing a flame retardant only in a small amount; and a flame retardancy determination method for determining the flame retardancy of a resin composition. The resin composition of the present invention comprises a thermoplastic resin, a cellulosic material, and a phosphoric-acid flame retardant and satisfies the following relationships (1) and (2). (In the relationships (1) and (2), TP, TB, and TCMP respectively indicate the following temperatures corresponding to peaks of weight loss rate in thermogravimetry: TP is the temperature (°C) at which the weight loss rate of the thermoplastic resin peaks, TB is the temperature (°C) at which the weight loss rate of the cellulosic material peaks, and TCMP is the temperature (°C) at which the weight loss rate of the resin composition peaks. In cases when the resin composition has two weight loss rate peaks, TCMP is the lower-temperature-peak temperature.)
