摘要：
本发明公开了一种高耐候性的PVC塑料，包括以下质量份的原料：PVC树脂：150-200份；增韧剂：1-5份；抗老化剂：2-7份；发泡调节剂：1-3份；光亮剂：0.2-0.5份；聚乙烯蜡：0.5-1.2份。本发明公开一种高耐候性的PVC塑料，通过特定的组分及含量选择，能使得该种PVC塑料具备很高的耐候性，从而满足使用要求。本发明还提供一种该高耐候性的PVC塑料的制备方法，该方法步骤简单，器件要求低，成本低，适合推广使用。
摘要（英）：

The invention discloses high-weatherability PVC plastic. The high-weatherability PVC plastic comprises the following raw materials in parts by mass: 150 to 200 parts of PVC resin, 1 to 5 parts of a flexibilizer, 2 to 7 parts of an age resister, 1 to 3 parts of a foaming regulator, 0.2 to 0.5 part of a brightener, and 0.5 to 1.2 parts of polyethylene wax. The high-weatherability PVC plastic has high weatherability through specific component and content selection, thereby meeting use requirements. The invention further provides a preparation method of the high-weatherability PVC plastic. The method is simple in steps, low in device requirement, low in cost and suitable for promotion and application.
