Description

Aromatic copolycarbonate resin composition and the optical data recording medium substrate, transparent optical element, cover for luminaire and the transparent member for vehicle that use this resin combination

Technical field

The present invention relates to a kind of aromatic copolycarbonate resin composition and utilize the purposes of its characteristic, described aromatic polycarbonate composition can solve article charged problem in the manufacturing process of these article.The present invention be more particularly directed to optical data recording medium substrate, transparent optical element, cover for luminaire (cover for luminaire) and transparent member for vehicle, when peeling off, the static content of peeling off that is produced has obtained reduction to above-mentioned article at employed mould when making or stamper (stamper).The invention particularly relates to pigment information recording carrier substrate, described pigment information recording carrier substrate is to be raw material and the optical data recording medium substrate that utilizes injection moulding to make to be mixed with aminated compounds and to utilize the aromatic copolycarbonate resin composition of scorification manufacturing, and the described pigment information recording carrier of manufacturing has prevented the generation of pigment coating spot especially when pigment being rotated coating with substrate.

Background technology

With the aromatic polycarbonate resin is that raw material and the substrate that utilizes the injection molding manufactured are widely used in CDs such as encryption disc, laser disk, optical disc, digital video disk and the near-field recording information medium purposes, described near-field recording information medium reads and is written as feature with what carry out signal in information faces (with respect to recording layer, the face relative with substrate).

This substrate is usually with following method manufacturing: form die cavity with the matched moulds state between fixed mould and moveable die, the smooth stamper of cyclic is set in this die cavity, by with the fused thermoplastic injection to die cavity, with preformatting information such as the signal (pit, indenture) of stamper or laser guide groove are carried out transcription.

In the substrate manufacturing, use aromatic polycarbonate resin at present, this is owing to can access high-quality information recording carrier substrate thus, excellences such as the transparency of this substrate, intensity, thermotolerance, dimensional stability, shock-resistance, and when carrying out the manufacturing of substrate with injection moulding, be located at trickle concavo-convex pattern (information signal) transcription correctly on the stamper quarter to the surface (transcription is good) of substrate (moulding product), and its camber is less, the planarity excellence.

Industrial making method as this aromatic polycarbonate resin, generally use the interfacial polymerization that dihydroxyphenyl propane and carbonyl chloride are reacted, but this method must be used industrial unworkable carbonyl chloride and methylene dichloride, thereby does not use above-claimed cpd and carried out the part industrialization with carbonic diesters such as aromatic dihydroxy compound such as dihydroxyphenyl propane and diphenyl carbonates as raw material and by the method that solvent-free transesterification reaction (scorification) is made polycarbonate a kind of in recent years.And the polycarbonate with above-mentioned transesterification reaction manufacturing becomes the material that is used to make encryption disc (CD) just gradually.Yet, in the optic disc base board by the polycarbonate manufacturing that utilizes No. 5606008 disclosed scorification of specification sheets of United States Patent (USP) to make, as its feature, if the scorification aromatic polycarbonate resin is resultant with the scorification of routine, its end has a lot of OH bases, thereby this OH base plays the effect of electronics acceptability group, and when breaking away from mould or stamper, the static on optic disc base board surface demonstrates strong especially negative polarity.Dust is attracted to the surface of moulding product by the powerful negative charge of this optical disc surface, may influence the final quality of CD.And, attract each other between the CD, in course of conveying, for example when injection moulding machine transports,, may cause occurring CD and make and stop or the situation that the yield rate of goods reduces and so on because CD is inter-adhesive.The problem that has also occurred coating spot (pigment coating spot) when in addition, utilizing rotary coating to be coated with pigmentary layer.

In addition, in the purposes of transparent optical element and cover for luminaire, because excellences such as the transparency of aromatic polycarbonate resin, thermotolerance, dimensional stability, shock-resistance, light weight, and when utilizing injection moulding and rotoforming manufactured optics, can access the few high-quality moulding product of camber, thereby in such use, bring into use aromatic polycarbonate resin, but compare with unorganic glass, there is the low problem that scratches easily of surface hardness in aromatic polycarbonate resin moldings.

So,, for example can after moulding, implement the operation that hard coat is handled is carried out on moulding product surface, but in this operation, adhering to of above-mentioned dust can become problem in order to give the aromatic polycarbonate resin moldings surface with scuff resistance.Handle if on the surface that is attached with dust, dust or particulate etc., carry out hard coat, then can form scraggly outward appearance, become the reason of the defective problem of outward appearance.Therefore, require the moulding charged moulding product that adsorb dust less and not afterwards.

On the other hand, as the problem that is caused by dust and adhering to of particulate after the assembling, the set lights that has adhered to dust seems fuzzy and turns white, and causes thus that outward appearance is defective, illuminating value is not enough, becomes the reason of the problem that commodity value reduces.

Under the situation that reads lens etc. of using up at photographies such as plastic lenss such as glasses, photographic camera-shooting machine particularly that the record learning plastic lens, be used for the information recording medium reads, when being assembled on the machine, because the structure of machine, be installed to mostly and be difficult to by wiping or blow off and remove on the position of dust, and less these operations difficulty that becomes that also makes of size.

And in most cases set lights is complex-shaped, perhaps as the situation that set lights is installed to eminence, is installed to mostly and is difficult to by wiping or blows off and remove on the position of dust, and this makes the clean operation difficulty that becomes.

And automobile adheres to two lip-deep dust of the outside of the outside of head lamp lens (lamp lens) and inner face, interior trim translucent cover and inner face and vehicle resin glass also becomes problem.It is in order to give scuff resistance to the aromatic polycarbonate resin moldings surface operation that hard coat is handled to be carried out on the surface of the moulding product after the moulding that dust adheres to an operation that becomes problem.Yet, produces when moulding product and mould are peeled off and peel off static, thereby it maintains negative charge.Make it from surrounding environment, adsorb dust and micropartical thus.Therefore,, can form scraggly outward appearance, become the reason of the defective problem of outward appearance if carry out hard coat on the surface of these dust and handle being attached with.That is to say, require the moulding charged moulding product that adsorb dust less and not afterwards.

In addition, when the transparent member for vehicle, also exist since dust when assembling and particulate adhere to the problem that causes.The words that for example in a single day are attached with dust in the inboard of head lamp just are difficult to remove simply.The lamp that particularly is attached with dust seems fuzzy and turns white, and causes outward appearance defective or illuminating value is not enough, becomes that commodity value reduces and the reason of variety of issue.And illuminating value also can guarantee to become problem aspect the driving safety inadequately.

At present, as suppressing the charged method of this aromatic polycarbonate resin, various static inhibitor have been proposed.

For example, people have proposed to mix the method (spy opens clear 64-14267 communique) of the method for an alkali metal salt of sulfonic acid, the phosphonium salt that mixes sulfonic acid and phosphorous acid ester, the amine salt that mixes sulfonic acid and the method (spy opens flat 3-64368 communique) of phosphoric acid ester etc.Yet the antistatic principle in these methods is, improves affinity with airborne moisture by making moulding product surface have polar group, forms moisture film on moulding product surface, makes the electric charge that is generated be easy to release by this moisture film.The static resistance of the aromatic polycarbonate resin that obtains with these methods is unstable sometimes, variation such as the transparency, tone, hydrolytic resistance, problem such as thermotolerance reduction when also having forming process.

And, thereby opening to have put down in writing in 2003-128903 communique and the Te Kai 2003-231801 communique at CD that use has a scorification polycarbonate resin the spy adds the method that static inhibitor improves the coating spot of pigment in substrate.But the main antistatic principle of the distearyl oxyamine of putting down in writing as this static inhibitor is not to suppress electric charge to generate, but has utilized the electric charge that is easy to be produced to discharge so existing antistatic principle.And because this static inhibitor has the amino of giving the positive charge effect and also contain in as polar group and have the OH base of giving the negative charge effect containing, thereby its negative electrostatic control effect to aromatic polycarbonate resin is relatively poor.In addition, the triphenylamine of same record has the positive charge of giving effect, its main antistatic principle is to suppress the generation of electric charge, but because it plays the effect of catalyzer, thereby aromatic polycarbonate resin decomposes and makes molecular weight reduce or optic disc base board has yellow such problem when having moulding.In addition, about pyridine-N-oxide, also exist because catalyst effect causes decomposition to cause optic disc base board to have yellow such problem.

Further, the spy opens and has put down in writing such content in the 2001-329157 communique,, in the various uses of using aromatic polycarbonate resin, in order to improve weathering resistance and thermotolerance, uses steric hindrance amine stablizer that is.Yet, aromatic polycarbonate resin with respect to 100 weight parts, be the amount of improving the stablizer that weathering resistance and thermotolerance use 0.1 weight part nearly, exist this moment as inferior problem and make it can not be used for purposes that described problem is: can not get electric charge and adjust effect as optic disc base board; Variation such as transparency tone, hydrolytic resistance; Exudate increases; And the thermotolerance during forming process reduces.

In addition, general aminated compounds itself has color mostly, and its transparency and tone scarcely are suitable for optic disc base board, and, because it has catalyst effect to aromatic copolycarbonate, the problem that molecular weight reduces when having forming process.

Summary of the invention

The present invention relates to aromatic copolycarbonate resin composition, and the optical data recording medium substrate, transparent optical element, cover for luminaire and the transparent member for vehicle that have used said composition.The surface that The present invention be more particularly directed to use stamper etc. and utilize the injection molding manufactured has the optical data recording medium substrate of indenture, groove, in more detail, relate to by erasable type or the type optical data recording medium of writing troactively the substrate that recording layer forms is set at this substrate table, say in further detail, relate to following pigment optical data recording medium substrate, in this substrate, be coated with pigment in order to form this recording layer and form pigmentary layer.The invention still further relates to following optical data recording medium substrate, adhesion between adhering to of dust or the substrate can not appear in this substrate, can be not during fabrication or occur the defective of the manufacturing that causes by static or production when using yet, have in the time of can improving the coating pigment because the pigment that the static of substrate surface produces is coated with the effect of spot.
