摘要:

近年來(lái)，從“限塑令”到“禁塑令”的升級(jí)，尤其是塑料包裝造成的白色污染問(wèn)題成為大眾關(guān)注的焦點(diǎn)，能夠進(jìn)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(yīng)用于藥品包裝、食品包裝等領(lǐng)域。隨著熱成型技術(shù)的發(fā)展，熱成型聚丙烯在家用冰箱內(nèi)襯、汽車結(jié)構(gòu)件、化工容器等大型制品中的應(yīng)用也日益增多。通過(guò)對(duì)國(guó)內(nèi)外聚丙烯在熱成型技術(shù)領(lǐng)域的相關(guān)專利申請(qǐng)進(jìn)行檢索、篩選和梳理，從技術(shù)方向、區(qū)域分布、專利申請(qǐng)趨勢(shì)、專利主要申請(qǐng)人、核心專利和技術(shù)演進(jìn)路線等多方面，綜述了近50年來(lái)技術(shù)人員對(duì)聚丙烯熱成型技術(shù)改進(jìn)研究等方面所采用的技術(shù)手段；分別分析了原料聚合、聚合后填充改性等5種技術(shù)方向的演進(jìn)路線，總結(jié)了聚丙烯材料在熱成型領(lǐng)域的應(yīng)用發(fā)展進(jìn)程，以期為該領(lǐng)域的技術(shù)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.
