Abstract
The target of this invention is to provide a fire resistance resin composite with a transparency in a certain range and excellent fire resistance. The fire resistance resin composite contains an aromatic polycarbonate resin (A component), a polyfluortetraethylene (B component) with ability of forming original fiber and a flame retardant (C component), wherein there are more than 0.01 part by weight but less than 0.1 part by weight of polyfluortetraethylene (B component) with ability of forming original fiber and 0.001 to 20 parts by weight of the flame retardant (C component) relative to the aromatic polycarbonate resin (A component) of 100 parts by weight.
Description
Technical field
The present invention relates to a kind of flame-retardant polycarbonate resin composition.More particularly, the flame-retardant polycarbonate resin composition that relates to a kind of transparency and excellent in flame retardance.
Background technology
Because aromatic polycarbonate resin not only has the transparency or excellent thermotolerance and intensity, but also has certain flame retardant resistance, thereby it is widely used in every field.But, the raising of the flame retardant resistance grade that causes with respect to the thin-walled property of raising that requires because of the flame retardant resistance of electronic apparatus machine part, OA associated components etc. in recent years or product, the flame retardant resistance of talkative aromatic polycarbonate resin is very inabundant.And, requiring to have the high flame retardant that meets V-0 among UL specification (American insurance dealer's proof test institute (the Underwriters Laboratories Inc))-94 recently under many circumstances, the PC material of having given high fire resistance seems extremely important.
In order to obtain high flame retardant, for example, drippage (drip) phenomenon of the resin when suppressing combustion test is important.As the method that suppresses drip phenomenon, known have as matrix resin use method, use the method for the polycarbonate resin of copoly type, add as Antidrip agent and have (with reference to the patent documentations 1~3) such as methods that fibril forms the tetrafluoroethylene (below, abbreviate fibrillation PTFE sometimes as) of ability as matrix resin with the unitary aromatic polycarbonate resin of side chain.
Wherein, use has the method for the unitary aromatic polycarbonate resin of side chain as matrix resin, though can expect to keep the transparency and have certain anti-drippage effect, but, the mobile shortcoming that reduces is arranged, if in the time of will suppressing the reduction (minimizing) of this flowability, exist the problem that loses anti-drippage effect again with respect to the unitary amount of the side chain of resin total amount.Use the method for the polycarbonate resin of copoly type as matrix resin, because its manufacture method is special, it is poor to make efficient, thereby, not only aspect practicality or the economy problem is being arranged, but also existing the problem that can not obtain anti-fully drippage effect.And the method for adding fibrillation PTFE, owing to obtain anti-drippage effect easily, and it is also few to add the reduction of the flowability that fibrillation PTFE causes, thereby it is applicable in the material (material with UL specification V-0, V-1) that requires high flame retardant more.But, the problem that it has the transparency to reduce.
In addition, the reduction of the transparency, the problem that not only has light transmission to reduce also is attended by the defective that the design space of the painted grade of the so-called part that comprises sensation diminishes.See conversely, then we can say the material that keeps the transparency, that is, the material that the mist degree in the moulding product is low (transparent high material), its design space of part that comprises sensation is big.Particularly, for the low material of mist degree, can use dyestuff is that tinting material is given transparent color (being commonly referred to as bone look (skeleton color)), further, can be coloured material combination or to use pigment separately be coloured material and give translucent color or opaque color with pigment also.And, can make light diffusing obtain to express by adding light diffusing agent, can give the light diffusing of targeted degree by the control addition.Therefore, the reduction of the transparency also is the reduction of transmittance, the painted difficulty that becomes that can make transparent color, thus make the part that comprises sensation and diminish the design space that further comprises the painted integral body of giving light diffusing.

Summary of the invention
The object of the present invention is to provide a kind of flame-retardant polycarbonate resin composition that can satisfy the transparency (mist degree) of excellent flame and certain limit simultaneously.
In order to solve the problems referred to above in the method for adding fibrillation PTFE, the inventor etc. have carried out concentrated research, it found that, be limited to the specified range of a small amount of scope by addition with fibrillation PTFE, can satisfy anti-fully drippage effect simultaneously, also promptly can satisfy sufficient flame retardant resistance and certain transparency (low haze valus), can keep the painted design space that comprises the sensation part simultaneously and the appearance design that obtains uniqueness, thereby finish the present invention.Promptly, by adding the mist degree that a spot of fibrillation PTFE expresses (when the time for the thick profiled sheeting of 2mm with limited range, mist degree is 2~17%) the aromatic polycarbonate resin material, the little by little atomizing that causes because of its a spot of fibrillation PTFE can bring the high aesthetic appearance of unique " sending out the transparency of mist ".And, find when this material of use, can keep and comprise painted design space sensation, functional part fully.
According to the present invention, a kind of flame retardant resin composition is provided, this resin combination comprises: aromatic copolycarbonate is resin (A composition) 100 weight parts; Have fibril form ability tetrafluoroethylene, be preferably the tetrafluoroethylene (B composition) that fibril forms ability that has of mixed style, its with respect to aromatic copolycarbonate be resin (A composition) 100 weight parts be 0.01 weight part above, be lower than 0.1 weight part; And fire retardant (C composition), it is that resin (A composition) 100 weight parts are 0.001~20 weight part with respect to aromatic copolycarbonate.
Flame retardant resin composition with above-mentioned composition, the transparency that can satisfy high flame retardant and certain limit simultaneously is (in the thick profiled sheeting of 2mm, mist degree is 2~17%), the space resin combination big, the outward appearance excellence of comparing painted design with the PC of in the past interpolation fibrillation PTFE can be provided, have the characteristic that conventional art does not have.
Embodiment
Below, illustrate in greater detail the present invention.
(A composition: aromatic polycarbonate resins)
The aromatic polycarbonate resins of using as the A composition is in the present invention reacted binary phenol and carbonic ether presoma and the resin that obtains.As the example of reaction method, can enumerate the solid phase ester-interchange method of interfacial polymerization, melt transesterification process, carbonic ether prepolymer and the ring-opening polymerization method of cyclic carbonate compound etc.
