に関して対応できるものではない。2. Description of the Related Art Conventional inorganic filler-filled composite polypropylene for automobile parts has provided a polypropylene composite material satisfying mechanical properties, heat aging resistance, light resistance, etc. which are present in the material specifications of automobile manufacturers. However, haze has become a problem in recent years. The haze means that the glass of an automobile is fogged by a volatile component emitted from an automobile interior part, which is a safety problem. Especially in the meter case, the acrylic lens is fogged to deteriorate the visibility. Conventionally, heat resistant agents, copper damage inhibitors, dispersants, etc. have been added to these materials, but there was a problem with haze.
In addition, it is possible to add an antistatic agent to the lamp-mounted component in order to prevent a decrease in illuminance due to dust adhesion, but it is not possible to deal with haze in particular.

後、埃付着性を目視判定した。[Various Test Methods] Test methods for haze, mold releasability, gear oven life and dust adhesion in Examples and Comparative Examples are as follows. Haze A single circular plate with a thickness of 1.6 mm and a diameter of 100 mm is used in the vertical direction 2
Divided and divided into 4 in the lateral direction, 8 pieces of test pieces with an inner diameter of 50 mm
It was placed in a glass bottle having a height of 115 mm and a diameter of 30 mm, and a glass plate having a thickness of 1 mm was attached to the opening, then, it was immersed in an oil bath from the bottle bottom to 50 mm and heated at 140 ° C. for 72 hours. The haze of the haze portion of the removed glass plate was measured with a haze meter manufactured by Nippon Denshoku Industries Co., Ltd. Mold releasability An injection molding machine manufactured by Ube Industries, Ltd., length 75 mm, width 100
The height of the ejector cylinder was measured by injection-molding a stepped box (two pieces) having a height of 45 mm, a thickness of 1.5 to 3 mm, and measuring the hydraulic pressure of the ejector cylinder. Gear Oven Life According to JIS K-7212, a gear oven manufactured by Toyo Seiki Co., Ltd. was used to measure the time until cracking or pulverization occurred on a test piece having a thickness of 1 mm at 150 ° C. Dust Adhesion A disk having a thickness of 1.6 mm and a diameter of 100 mm was suspended at a position of 4 m in height in a molding factory immediately after molding, and left for 10 days, and then the dust adhesion was visually evaluated.
