Abstract
Provided is a method for manufacturing a light reflector made of polybutylene terephthalate resin which has extremely high surface gloss of a molded product and little production of gas so that a light reflecting metal layer can be directly formed on the molded product without applying a primer coat such as undercoat onto the molded product and which has not only high mirror surface property/high luminance appearance but excellent adhesiveness with the metal layer/heat resistance. The reflector is obtained by molding a resin composition containing: (A) 100 pts. wt. of polybutylene terephthalate resin; (B) 5 to 80 pts. wt. of polyethylene terephthalate resin; (C) 0.05 to 2.0 pts. wt. of polyglycerin stearate; (D) 2 to 50 pts. wt. of non-fibrous inorganic filler having <=5 [mu]m average primary particle size; and (E) 0.1 to 3.0 pts. wt. of an antioxidant. Then a light reflecting metal layer is formed on at least a part of the molded product.
Description
Technical field
The present invention relates to the manufacture method of the reflective optical system that polybutylene terephthalate makes, and the reflective optical system that obtains with this method.More specifically, the present invention relates to the manufacture method of the reflective optical system that polybutylene terephthalate makes, the surface gloss of the mechanograph of making according to this method is very high, and suppressing gas produces, thereby in continuously moulding, obtain outward appearance excellence, goods that turbidity is little, thereby can directly form reflective metal layer in molded article surface, and do not need any undercoat; The invention still further relates to the reflective optical system that polybutylene terephthalate is made, this reverberator not only guarantees high gloss, also guarantee to keep excellent appearance (thermotolerance) when at high temperature using, and excellent and cohesive metal level.
Resin-based reflective optical system of the present invention is preferably used for the parts around the lamp in auto industry, building measurement instrument industry and the various industrial circle.Particularly, this reverberator is preferably used for requiring reverberator, extension around the auto lamp of high surface gloss, high surface flatness and the high optical reflection degree parts that grade.
Background technology
Up to now, to being used for the reverberator that the auto lamp extension grades, aspect high gloss, high smooth degree, uniform reflectance and high-fire resistance, adopted the crystallization thermoplastic vibrin, especially independent polybutylene terephthalate, or the material that obtains of the blending of the potpourri by various reinforcing agents and polybutylene terephthalate and polyethylene terephthalate; After mechanograph carried out pre-service (primary coat),, form reflective metal layer, thereby obtain the reflective optical system of target in molded article surface by technology such as the vacuum vapor deposition technology.
Yet,, therefore require to obtain even without any the high gloss reflective optical system of undercoat because primary coat sharply increases cost.In order to make the reverberator that forms the reflective metal layer of no undercoat at least one surface of mechanograph have high gloss and uniform reflectance, resin formed article itself must have excellent surface smoothness and high gloss.In addition, the thermotolerance of resin sees it also is a major issue from its applicable cases.
As the resin material that is used for this purpose, the applicant has proposed a kind of composition that comprises the polybutylene terephthalate of polyethylene terephthalate and non-fibrous inorganic filler in JP-A 2000-35509.In this resin material, some effective measures shows on the surface smoothness and glossiness as above-mentioned purpose.Yet according to research subsequently, therefore some deficiency of image sharpness when high temperature is used down requires further to improve.In lamp part, except that above-mentioned performance, also require at camera lens or the optical haze that do not produce on glass.
Therefore, need a kind of reflective optical system of exploitation, even this reflective optical system no any undercoat ground directly during the vapour deposition reflective metal layer on resin formed article, also have excellent glossiness, high reflectance and excellent metal adhesion, even and at high temperature use and also can have the thermotolerance that keeps these performances.
