Eggshell powder-containing thermoplastic resin composition and molded product

摘要

PROBLEM TO BE SOLVED: To use a thermoplastic resin composition capable of producing a molded product in which the eggshell powder is highly filled in the thermoplastic resin, the uneven distribution thereof is suppressed, and the appearance and mechanical properties are good. Provide molded products. SOLUTION: In an eggshell powder-containing thermoplastic resin composition containing a thermoplastic resin and eggshell powder in a mass ratio of 50:50 to 10:90, the mass of the eggshell powder with respect to the entire eggshell powder-containing thermoplastic resin composition. The ratio is 50/100 or more, the BET specific surface area of the eggshell powder is 0.1 m2 / g or more and 10.0 m2 / g or less, and the roundness of the eggshell powder is 0.50 or more and 0.95 or less. The eggshell powder shall include at least two groups of particles, one is an eggshell powder group having an average particle size of 0.7 μm or more and less than 2.2 μm, and the other is an eggshell powder group having an average particle size of 2.2 μm or more and less than 6.0 μm. It is an eggshell powder-containing thermoplastic resin composition characterized by the above, and a molded product using the same. [Selection diagram] None
