Problems solved by technology

If it is not handled properly, it will cause serious pollution to the environment and may also become the source of epidemics
At present, there is a certain standard mechanism for the treatment of medical waste, but it will inevitably cause people's unhappiness during the production and treatment of medical waste. At the same time, certain packaging containers are required to facilitate transportation during the treatment process. Materials that can deodorize are used as containers for these wastes, which can reduce the negative impact on people during the generation, storage and disposal of such wastes

Abstract

The invention discloses a preparation method of a medical deodorization packaging material. According to the method, PVC (polyvinyl chloride), dioctyl phthalate, lauric acid, sodium tripolyphosphate, polycarbonate and barium stearate are added into a mixing stirring machine to be stirred and uniformly mixed; then, the materials are transferred into a reaction kettle; glass fiber, methyltetrahydrophthalic anhydride, aluminium oxide and 3-allene-2-acryloyloxy-1-potassium sulfonate are added; the materials are heated under the negative pressure condition to take reaction; the mixture is dried and crushed; then, ammonia gas is used for suffocating; finally, the extrusion forming is performed through a double-screw extruding machine; the medical deodorization packaging material is obtained. The deodorization packaging material prepared by the preparation method provided by the invention has good mechanical performance and deodorization performance, and can be better applied to the field of medical care and sanitation.

Description

Technical field [0001] The invention belongs to the field of medical materials, and particularly relates to a method for preparing medical deodorizing packaging materials. Background technique [0002] Medical waste refers to contaminated waste produced by hospitals that have been in contact with patients' blood and flesh. Such as used cotton balls, sand cloth, adhesive tape, waste water, disposable medical equipment, post-operative waste, expired drugs, etc. According to the medical inspection report of the national health department, due to the characteristics of space pollution, acute infection and latent pollution of medical waste, the harmfulness of viruses and bacteria is dozens, hundreds or even thousands of times that of ordinary household waste. If not handled properly, it will cause serious pollution to the environment and may also become the source of the epidemic. At present, there is a certain standard mechanism for the treatment of medical waste. However, the prod...
