Example Embodiment

[0060] Example 1

[0061] The ultra-high performance plastic film in this embodiment has a single-layer structure, and a single-layer extrusion casting process is selected during preparation, and the thickness of the prepared film is 0.097 mm.

[0062] The formula weight composition of the film is as follows: 9.52% ultra low density polyethylene, 85.72% metallocene linear low density polyethylene, 3.33% color masterbatch, 1.43% other additives.

[0063] The performance of the plastic film prepared by the above formula is compared with the performance of the existing operating table cloth on the market as follows:

[0064]

[0065] It can be seen that the tensile strength of the film in this example is more than 2 times that of the existing operating table cloths on the market; the dart impact is more than 5 times that of the existing operating table cloths on the market; the tear strength is higher than that of the existing operating table cloths on the market. There are 1.1 times mor...

[0069] Example 2

[0070] The ultra-high-performance plastic film in this example has a two-layer structure of A layer and B layer. The two-layer extrusion casting process is selected during preparation. The thickness of the prepared film is 0.097mm. The A layer and B layer structures are both formulated as follows :

[0071] The weight composition of the A-layer formula is as follows: 9.52% ultra-low density polyethylene, 85.72% metallocene linear low density polyethylene, 3.33% color masterbatch, 1.43% other additives.

[0072] The weight composition of the B layer formula is as follows: 9.76% ultra-low density polyethylene, 87.8% metallocene linear low density polyethylene, 0.98% color masterbatch, and 1.46% other additives.

[0073] The performance of the film prepared by the above formula is compared with the performance of the existing operating table cloth on the market as follows:

[0074]

[0075] It can be seen that the tensile strength of the film in this example is more tha...

[0079] Example 3

[0080] The ultra-high-performance plastic film in this embodiment has a three-layer structure of A-layer, B-layer and C-layer. A three-layer extrusion casting process is selected during preparation. The thickness of the prepared film is 0.097mm, of which A-layer, B-layer and C-layer The layer structure uses the following formula:

[0081] The weight composition of the A-layer formula is as follows: 22.83% ultra-low density polyethylene, 68.49% metallocene linear low density polyethylene, 7.31% color masterbatch, 1.37% other additives.

[0082] The weight composition of the B-layer formula is as follows: 14.63% ultra low density polyethylene, 68.29% metallocene linear low density polyethylene, 14.63% high density polyethylene, 0.99% color masterbatch, 1.46% other additives.

[0083] The weight composition of the C layer formula is as follows: 9.52% ultra-low density polyethylene, 85.72% metallocene linear low density polyethylene, 3.33% color masterbatch, 1.43% addit...

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...
