The medical protective film comprises an upper-layer film, a middle-layer film and a lower-layer film which are sequentially adhered together, wherein the upper-layer film and the lower-layer film consist of the same components; the middle-layer film consists of 10-40 parts of linear low-density polyethylene, 10-40 parts of low-density polyethylene, and 20-80 parts of metallocene medium-density polyethylene or metallocene high-density polyethylene; the upper-layer film consists of the components of 10-30 parts of metallocene medium-density polyethylene or metallocene high-density polyethylene, 32-52 parts of low-density polyethylene, 30-50 parts of linear low-density polyethylene, 0.5-0.8 part of zeolite and 0.01-0.2 part of a slipping agent. According to the medical protective film with high transmittance, provided by the invention, after the film is disinfected for 8 hours and when the disinfected film is taken out and unfolded, the overlapped parts are not mutually adhered and are easy to separate, and the surface is smooth; besides, the film has higher transmittance.
Description
Technical field
The present invention relates to a kind of composite plastic film, be specifically related to a kind of high transmission rate medical protection film and preparation method thereof.
Background technology
After polluting according to article, by hospital's article, high-risk, middle danger, low danger three class are divided into the extent of injury of human body, diagnosis and treatment equipment and the article of serious harm can be caused, such as operating theater instruments and articles for use, transfusion and blood transfusion equipment etc. after described high-risk article means microbial contamination.The principle of hospital is that all high-risk articles must select the sterilizing of high-effective disinfecting method, makes its sterilizing index reach 10
-6even if (microorganism survive probability ﹤ 10
-6).The disinfectant that conventional high-effective disinfecting method uses has glutaraldehyde, formaldehyde, Peracetic acid, hydrogen peroxide, oxirane and ozone etc., and the disposable film in its surgery, operation table laid is suitable for adopting oxirane as disinfectant.
Can there is non-specific alkylating with the protein of microorganism, DNA and RNA in oxirane, strong to the penetration power of sterilizing objects, can reach article deep, can kill various pathogenic microorganism, comprise bacterial propagule, gemma, virus and fungi.The gaseous state of oxirane and liquid form all have stronger function of killing microorganism, especially the bactericidal action of gaseous ethylene oxide is stronger, therefore its gas multiplex, gas fumigation sterilization is carried out to medicine, surgical instruments and medical film etc., ideal Disinfection Effect can be obtained.
When but reality is to medical film disinfection, film-folding to be sterilized is folded and is placed in closed container, pass into ethylene oxide gas, sterilize after 8 hours by film take out launch time, find adhesion mutually between the position that medical film is stacked place, launch not easily, if force external force quick separating, the surface of film otherwise smooth becomes coarse, does not just meet the requirement of operation.
When reality uses medical film, doctor is through medical film inspection apparatus camera lens etc., have higher requirement, and the light transmittance of existing medical film is generally lower to the light transmittance of medical film.
Summary of the invention
