Problems solved by technology

[0005] However, polycarbonate resin compositions incorporating condensed phosphate esters do not necessarily provide a satisfactory balance of light resistance and heat resistance, impact strength and fluidity
In addition, condensed phosphate ester flame retardants involve another problem of lack of synergistic flame retardant effect when used in combination with the silicone compounds of the present invention

Embodiment

[0088] Example description

[0089] The present invention is explained more specifically by using the following examples, but the present invention is not limited to these examples. Unless otherwise noted, the term "parts" means "parts by weight".

[0090] The materials used in the experiments are described below.

[0091] 1. Polycarbonate resin (hereinafter referred to as "PC")

[0092] Sumitomo Dow Caliber-200-20, molecular weight: 18,600.

[0093] 2. Silicone compound (hereinafter abbreviated as "SI").

[0094] Silicone compounds are prepared according to commonly practiced preparation methods.

[0095] That is, an appropriate amount of diorganodichlorosilane, monoorganotrichlorosilane and tetrachlorosilane or their partially hydrolyzed condensates are dissolved in an organic solvent. Water is added to cause hydrolysis and partially condensed siloxane compounds. In addition, triorganochlorosilane was added and allowed to react to complete the polymerization. The solv...

Abstract

A flame-retardant polycarbonate resin composition which comprises 100 parts by weight of a polycarbonate resin (A), 0.01 to 3 parts by weight of a silicone compound (B) having a branched main chain and having either an aromatic group or an aromatic group and a hydrocarbon group (excluding aromatic groups), 0.5 to 20 parts by weight of a phosphazene compound (C), 0.01 to 2 parts by weight of an organic metal salt (D), and 0.01 to 2 parts by weight of a fiber-forming fluoropolymer (E). It may optionally contain 5 to 25 parts by weight of titanium oxide (F) and 0.05 to 2 parts by weight of polyorganohydrogensiloxane (G).

Description

technical field [0001] The present invention relates to a flame-retardant polycarbonate resin composition obtained by formulating a specific siloxane compound, a specific phosphazene compound, a specific organic metal salt, a fiber-forming, containing Fluoropolymers, and when required, specific titanium dioxide and poly(organohydrogensiloxanes). The flame-retardant polycarbonate resin composition of the present invention has excellent flame retardancy, and also has excellent mechanical strength, moldability and good appearance. Therefore, the composition can be used in a wide variety of application fields, especially in the fields of electric equipment, electronic equipment, OA and the like. Background technique [0002] Polycarbonate resins are thermoplastic resins having excellent impact resistance, heat resistance, etc., which are widely used in fields such as electrical, electronic, OA, mechanical, and automotive applications. In addition to the excellent properties ex...
