Abstract: PURPOSE: A sun visor for absorbing impact is provided to recycle the sun visor without pollution by making the sun visor of polypropylene foam, and to increase the productivity and to cut down expenses by simplifying the manufacturing process with injection molding. CONSTITUTION: A sun visor of a vehicle is composed of a frame and a pad member. The frame is made of plastic or steel material, and the pad member is made of polypropylene foam. The bead blowing polypropylene foam includes 10-25 wt% low-density polyethylene copolymerizing 7-20%, homo polypropylene of 25-45 wt%, block polypropylene of 25-35 wt% and copolypropylene of 1-10 wt%. The strength is improved, and impact is absorbed by enhancing the bonding force. The weight is reduced, and recycling is convenient with manufacturing the sun visor by polypropylene foam. The manufacturing process is simplified with forming the frame through injection molding.

Abstract translation: 目的：提供吸收冲击的遮阳板，通过制造聚丙烯泡沫的遮阳板，无污染地回收遮阳板，并通过注塑成型简化制造工艺，提高生产率和降低成本。 构成：车辆的遮阳板由框架和衬垫构件组成。 框架由塑料或钢材制成，衬垫构件由聚丙烯泡沫制成。 发泡聚丙烯泡沫包括10-25重量％的共聚7-20％的低密度聚乙烯，25-45重量％的同质聚丙烯，25-35重量％的聚丙烯和1-10重量％的共聚丙烯。 强度提高，冲击力通过提高粘接力而被吸收。 减轻重量，通过聚丙烯泡沫制造遮阳板，回收便利。 通过注塑成型框架，简化了制造工艺。
