摘要:

近年來，從“限塑令”到“禁塑令”的升級，尤其是塑料包裝造成的白色污染問題成為大眾關注的焦點，能夠進行回收利用的聚丙烯是目前成本效益最高的環(huán)境友好型樹脂之一,尤其是熱成型專用聚丙烯廣泛應用于藥品包裝、食品包裝等領域。隨著熱成型技術的發(fā)展，熱成型聚丙烯在家用冰箱內(nèi)襯、汽車結構件、化工容器等大型制品中的應用也日益增多。通過對國內(nèi)外聚丙烯在熱成型技術領域的相關專利申請進行檢索、篩選和梳理，從技術方向、區(qū)域分布、專利申請趨勢、專利主要申請人、核心專利和技術演進路線等多方面，綜述了近50年來技術人員對聚丙烯熱成型技術改進研究等方面所采用的技術手段；分別分析了原料聚合、聚合后填充改性等5種技術方向的演進路線，總結了聚丙烯材料在熱成型領域的應用發(fā)展進程，以期為該領域的技術人員提供參考和研究方向。

Abstract:

In recent years, the policy upgrading from “plastic restriction order” to “plastic prohibition order”, especially the white pollution caused by plastic packaging, has become a focus of public attention. Polypropylene can be recycled, it is one of the most cost-effective environment-friendly resins at present. In particular,special polypropylene for thermoforming is widely used in microwave appliances, food packaging and other fields. With the development of thermoforming technology, the application of polypropylene thermoforming technology in household refrigerator lining, automobile parts, chemical containers and other large products is also increasing. This article analyzes and introduces the patent applications of polypropylene in the field of thermoforming technology in the past 50 years. The patents are searched,screened and sorted in the worldwide patent database from the technical direction, applicant regional distribution, patent application trends,main patent applicants, core patents and technology evolution routes. It summarizes the technical means used by technicians in recent decades for the application improvement of polypropylene materials in thermoforming technology. It also explores evolution routes of 5 kinds of patented technologies, such as the polymerization of raw materials, filling modification after polymerization, etc. In a word, this article summarizes the application development process of polypropylene materials in the field of thermoforming and may provide reference value and research direction for technicians in this field.
