Description of the invention: [Technical field to which the invention belongs] The present invention relates to a thermoplastic molding composition, which is a composition that is weather-resistant, colored, and impact-resistant. j 疋 一 [Prior art] From the true Γ3 to the day of the wound, polyester, non-crystalline polycarbonate, grafting == impact-resistant modified molding composition is a conventional mold =: = _ for molding, such as : Bumper stop 3, cover for headlights, cover for tailgate, prerequisites for automotive applications: need: high fluidity, good concentration, solution dimensional stability, and low temperature High-hardness chemical, alkaline, south blended formic acid / polycarbonate moulding paint-a different method of coloring. Traditionally, before the primer is applied, the base layer can be primed with a primer. On top, an externally applied primer and / or filled with these systems are optionally applied to the primer below. Painting, painting ΐ: those who are incorporated into the internal coloring system can substitute for the upper, internal coloring system. The color of the mold used is 200538506, which is determined by the inherent color of the plate and plastic composition, that is, the mold. Into the internal coating: not using a primer, filler, or colored primer coating: = Second, the molding into the coloring system can optionally use transparent and colorless, * soil cover. The advantage of the molded in-coloring system is that it can save money. The following processing steps are omitted. · Drying with primer and / or filler = coating and painting with colored primer and related dry acid vinegar modification The weatherability of poly (terephthalate) / polycarbonate ^^ The automotive exterior sector has requirements for the resistance to irradiation of molding materials. In this specification, the water resistance of the UV material is hereinafter referred to as UV stability) and the material is important. Destructive effects (hereinafter referred to as hydrolytic stability). In the paint system, most of the harmful UV rays are undercut. On the other hand, the UV blocking function in the molding coloring system . For molding into the internal coloring system ;, UV outer line · absorbent transparent paint can stop most harmful: private line shot. However, the molding electrical use based on the molding-in-coloring system must have high UV stability. For this reason, it cannot be used alone as an impact modifier based on rubbers with conjugated diene. Diene in ABS or MBS rubber.
