Abstract
The invention discloses an anti-static transparent polycarbonate material which is composed of a mixed system of polycarbonate resin and antistatic agent, in addition, anti-oxidant, ultraviolet light stabilizing agent, mould release agent, and the like can be selectively added, wherein the antistatic agent comprises alkyl stearate, ethoxy alkyl amine, alkyl benzene sulfonic acid-four-alkyl phosphonium salt and alkyl perfluoro sulfonic acid imidazole salt. Two or more than two antistatic agents with different varieties added into the polycarbonate material according to a certain ratio is adopted in the invention, the total adding quantity accounts for 0.5 percent to 4 percent, the material and products thereof can obtain very good anti-static performance and transparency and have good thermal stability, the anti-static transparent polycarbonate material can be used for producing transparent polycarbonate products which are sensible to static electricity, such as compact disk, electronic products, anti-static film products, and the like.
Description
Technical field
The present invention relates to a kind of polycarbonate material and preparation method thereof, relate in particular to a kind of novel electrostatic resistant transparent polycarbonate material and manufacture method thereof.
Background technology
Polycarbonate is a kind of important engineering plastics, has over-all propertieies such as excellent shock resistance, optical transparence, electric insulating quality, dimensional stability.Therefore polycarbonate is widely used in numerous optical articles such as laser disc, headlight for vehicles, and the optical correction eyeglass is during sheet material etc. are used.Although polycarbonate has plurality of advantages, but because its chemical structure decision, in production of articles, material and metal die are easy to produce electric charge when breaking away from and are enriched in the surface, cause that the goods yield descends thereby cause in the air dust to be adsorbed onto product surface, even the electronic product malfunction.
Produce in order to reduce surface charge, a large amount of static neutralising arrangements such as static fan etc. are installed in the production of articles link.Though its performance improves in a short time, it can not eliminate static fully.And the static that is produced in the goods secondary processing also can't be eliminated.
Also there are some antistatic coating products such as ITO coating and antistatic polyurethane coating to be developed to be coated with and install to the polycarbonate article surface, play the elimination electrostatic interaction.But bring coating and polycarbonate article bounding force deterioration again simultaneously, the anti-scratch performance of coating is not good, and the secondary processing flow process causes producing degradation misgivings under the yield.The raising greatly that the while coating technology can be brought tooling cost.
Therefore there is multiple polycarbonate material modification technology to be developed, thereby eliminates generation of static electricity from the raw material level.Thereby a kind of method is the graphite, the metallic particles that add conduction in polycarbonate material reduces product surface resistance, reduces the electric charge enrichment.But generally need big conductive additive and polycarbonate thorough mixing can effectively play antistatic effect.This has brought goods opaque again simultaneously, and it is big that difficulty of processing becomes, the contradiction that the conductive additive cost is higher.
Another kind method is used as static inhibitor for adding multiple aniorfic surfactant in polyethylene, polypropylene articles.But because itself and the relatively poor and very difficult quilt of polycarbonate material consistency effectively disperse, and it moves to the polycarbonate article surface easily at short notice, in addition after the goods water cleans, thereby static inhibitor is easy to be washed off and causes the antistatic life-span of goods not long.
Also have a kind of method promptly to add nonionic surfactant such as Vinlub, this tensio-active agent and polycarbonate have consistency preferably comparatively speaking, but need bigger addition just can play good antistatic property, simultaneously, Vinlub cause in the production of articles coal mine gas to discharge fully owing to being enriched in product surface in a large number, product surface produces oil drop, and yield descends.
Therefore, the anti-static polycarbonate material of a kind of shock resistance that can keep the polycarbonate excellence of exploitation and optical transparence is one of this area scientific research personnel key technical problem of doing one's utmost to study always.
Summary of the invention
Purpose of the present invention provides a kind of novel electrostatic resistant transparent polycarbonate material exactly in order to address the above problem.
Another object of the present invention also is to provide a kind of preparation method of the present invention.
The object of the present invention is achieved like this:
