Ultrahigh-performance plastic film as well as preparation method and composite material thereof

Abstract

The invention relates to an ultrahigh-performance plastic film as well as a preparation method thereof. The film is a one-layer structure of a multilayer structure. At least one layer structure in the film adopts the following formula by weight percent: 0 to 100 percent of metallocene linear low-density polyethylene, 0 to 100 percent of linear low-density polyethylene, 0 to 80 percent of low-density polyethylene, 0 to 60 percent of ultralow-density polyethylene, 0 to 60 percent of high-density polyethylene and 0 to 30 percent of additives. The invention also relates to a composite material which is prepared by compounding the ultrahigh-performance plastic film and a fiber material. When used as operation tablecloth, the composite material has the multiplied performance of the existing operation tablecloth, such as tensile strength, impact resisting strength, tearing resistance and the like.

Description

technical field [0001] The invention relates to an ultra-high-performance plastic film, a preparation method thereof, and a composite material obtained by compounding the film and a fiber material. Background technique [0002] Polymer materials, or plastics or resins, can be processed into various products according to their uses due to their excellent plasticity. Among them, polyethylene is widely used because of its easy access to raw materials, easy processing, low price, and tasteless and non-toxic. Polyethylene is also one of the main materials used in fields such as injection molded parts, extruded pipes and blow molded parts, as well as films made by cast and blown film processes. [0003] Films made of polyethylene are also widely used in medical products, such as operating tablecloths, surgical gowns, pathological specimen bags, isolation materials, liquid collection bags, Meishi sleeves, finger gloves, medical equipment covers and surgical drapes, etc. Among them...

AI Technical Summary

Problems solved by technology

These film products need to have a certain strength to achieve the function of preventing cross-infection. With the development of medical technology and the emergence of various new infectious viruses (especially highly infectious diseases such as avian influenza, SARS and foot-and-mouth disease), the protection of products The functional requirements of cross-infection are getting higher and higher, and the performance of the existing medical films on the market, especially the operating tablecloth, can no longer meet the new needs. Therefore, it is urgent to develop a new film with higher performance to ensure that It will not be damaged during use to reduce the possibility of cross-infection, such as not breaking under high-strength stretching, not piercing under high-impact force, and not cracking under strong tearing, etc.
