Problems solved by technology
[0011] The purpose of the present invention is to solve the problem of adding a fluorine-containing organic metal salt compound in order to impart flame retardancy or static electricity prevention to an aromatic polycarbonate resin colored with titanium dioxide and a fluorescent whitening agent, so as to make it different from the original white color. The problem of the different colors of the system whose hue is very different

[0209]The resin composition described in Table 1 was prepared according to the following method. In addition, the description is based on the symbols in the following table. The components in the ratios in Table 1 were measured and uniformly mixed with a rotating machine, and the mixture was introduced into an extruder to prepare a resin composition. As the extruder, a vented twin-screw extruder (KTX-30, manufactured by Kobe Steel Co., Ltd.) with a diameter of 30 mmφ was used. The screw structure is that the first stage of kneading area (consisting of removing kneading disc×2, removing rotor×1, returning rotor×1, returning kneading disc×1) before the position of the exhaust port is set after the position of the exhaust port The kneading area of the second stage (consisting of the removal rotor×1, the return rotor×1). Under the conditions of cylinder temperature and mold temperature of 280°C, and exhaust port vacuum of 3000 Pa, the strands were extruded, cooled in a water bath, a...

The invention aims to solve the problem that color of the aromatic polycarbonate resin in which white series coloration is performed by titanium dioxide and fluorescent brightening agent is different from the color phase of original white series, which is caused by adding fluoric organic metal salt compounds having flame resistance or anti-static performance; that is to say, a resin compound which has little color phase difference in relation to the resin compounds not coordinated to the fluoric organic metal salt compounds can be obtained by coordinating the fluoric organic metal salt compounds to the aromatic polycarbonate resin in which white series coloration is performed by titanium dioxide and fluorescent brightening agent. The invention provides a flame resistance resin composition which comprises 100 parts by weight of aromatic polycarbonate resin; 0.005-30 parts by weight of titanium dioxide; 0.0001-1 parts by weight of fluorescent brightening agent; and 0.005-0.6 parts by weight of fluoric organic metal salt compounds; wherein, fluorescent brightening agent is the fluorescent brightening agent whose molecular structure is free in thiophene skeleton.
Description
Technical field [0001] The present invention relates to a flame-retardant aromatic polycarbonate resin composition. The flame-retardant aromatic polycarbonate resin composition contains titanium dioxide, a fluorescent whitening agent, and an alkali metal salt of perfluoroalkyl sulfonic acid. Representative fluorine-containing organic metal salt compounds. Background technique [0002] Since aromatic polycarbonate resins have excellent transparency, flame retardancy, and impact resistance, they are widely used in various fields. Furthermore, in order to impart different colors to aromatic polycarbonate resins according to different applications, a method of compounding various colorants is known, but in order to impart a white color, titanium dioxide is often used. Furthermore, it is known that the addition of a fluorescent whitening agent can achieve unique and bright coloring with fluorescence. For example, the combined use of titanium dioxide and fluorescent whitening agent is ...
