Description

The present invention relates to an aromatic polycarbonate resin composition and a molded article thereof, and more specifically, an aromatic polycarbonate-polyorganosiloxane copolymer, an aromatic polycarbonate, an aliphatic polyester, a naturally occurring organic filler and an inorganic filler in a specific ratio. And an aromatic polycarbonate resin composition having excellent mechanical properties and flame retardancy, and a molded article comprising the same.
This resin composition can be used in the fields of OA equipment, information communication equipment, home appliances, and the like.

Polycarbonate resins have excellent mechanical properties such as impact resistance, heat resistance, and transparency, so they are used in various fields such as electrical, electronic, OA equipment, machinery, and automobiles. In addition, there is a problem of reducing the load on the environment, which has been a problem in recent years in terms of degradability after use.
On the other hand, many aliphatic polyester resins are biodegradable, and have attracted a great deal of attention in that the burden on the environment after use is small.
In particular, polylactic acid resin made from plant-derived raw materials such as corn and sugarcane can be reduced to water and carbon dioxide (carbon neutral). Is progressing.
Furthermore, since it has a high melting point as a vegetable plastic and can be melt-molded, it is expected to be used as a vegetable / biodegradable resin that is practically excellent (for example, Patent Document 1).
Also, some petroleum-derived aliphatic polyester resins (for example, Patent Document 2 and the like) have been attracting attention since some of the raw materials are supposed to be switched to plant-derived materials in the future.
However, since aliphatic polyester resins such as polylactic acid have low mechanical properties such as heat resistance, it is difficult to use a single unit as a molded product for a member that requires mechanical strength.
Therefore, attempts have been made to solve this problem by alloying an aliphatic polyester resin with an aromatic polycarbonate (for example, Patent Documents 3 and 4).
On the other hand, as one of the methods for improving the mechanical properties and heat resistance of the aliphatic polyester resin, a method using an inorganic filler such as glass fiber has been studied. There are problems such as an increase in the specific gravity of the product and an increase in the environmental impact due to an increase in residues that become garbage during incineration or disposal.
In order to solve these methods, a method of blending a naturally-derived organic filler having a light specific gravity and a small environmental burden is being compared with an inorganic filler.

Regarding the method of increasing the rigidity using an inorganic filler such as glass fiber or carbon fiber, there is a problem that accompanied by a decrease in fluidity and an increase in specific gravity.
For this reason, the use of organic fillers has been studied as an alternative. For example, Patent Document 5 describes the content of blending a naturally-derived organic filler with a polyester resin such as polylactic acid, but there is no description regarding improvement of fluidity and rigidity.
Further, there is no known patent document that mentions improvement in flame retardancy of a composition obtained by adding a naturally-derived organic filler to an alloyed aromatic polycarbonate / aliphatic polyester.
