Problems solved by technology

[0006] On the other hand, the existing composite materials that use film and fiber materials, such as Meishi sleeves, usually use a flat polyolefin film. After the polyolefin film is combined with a hydrophilic fiber fabric, the surface of the film is smooth The film is closely attached to the fiber fabric, and the total water absorption capacity of the Meishi sleeve is limited to the water absorption capacity of the hydrophilic fabric itself

Abstract

The invention relates to a composite material and application thereof. The composite material comprises a thin film with a particle hand feeling and a fiber material compounded on the surface of the thin film, wherein the thin film is of a structure of one layer or more than one layer; the raw material formula with at least any one layer of structure in the thin film comprises ultra-high molecular weight polymer particles; the ultra-high molecular weight polymer particles have the diameter of 10-500 microns, the molecular weight of 1-7 million and the melting point of 125-180 DEG C. According to the composite material disclosed by the invention, the ultra-high molecular weight polymer particles are added into the raw materials of the thin film formula, so that the surface of the thin film has a raised effect with the particle hand feeling. Moreover, due to the raised uneven surface of the thin film, the space between the thin film and the fiber material is enlarged, so that the composite material disclosed by the invention has high water absorbent rate and high water absorption capacity.

Description

technical field [0001] The invention belongs to the field of polymer materials, is applied in the medical and health industry, and relates to a composite material and its application. Background technique [0002] In the operating room of a hospital, a mayo stand (commonly referred to as a tray) is a stainless steel frame used to place surgical instruments, trays, drugs and other surgical supplies. The Mayo stand generally consists of a larger stainless steel tray and C Composed of a stand with pulleys. When using the mayo stand cover, a mayo stand cover (usually called a surgical tray cover) should be put on the outside to prevent cross-infection, and it can also be used to collect medical waste after the operation. The Meishi sleeve is generally made of polyolefin film and fiber fabric, one end is closed and the other end is open. [0003] The open end of the Mei's sleeve needs to be opened before use so that it can be inserted into the front of the Mei's tray first. In...
