Problems solved by technology

[0002] Medical gloves are a kind of medical consumables. In order to avoid cross-infection of germs, doctors have to change gloves every time they examine a patient. The amount of use is large. Therefore, countless waste disposable gloves are produced every day, causing serious white pollution to the environment. ;The main material of disposable gloves commonly used at present is high-density polyethylene or low-density polyethylene. Therefore, the softening deformation temperature is lower, and it cannot withstand high-temperature heating and sterilization. However, using other sterilization methods will cause environmental pollution and chemical reagent residue on the surface of the glove, making it difficult to use the glove multiple times; It can not only reduce medical consumables, but also save the treatment cost of medical waste and reduce white pollution

Abstract

The invention relates to the technical field of medical appliances, and discloses high-temperature-resistant medical gloves, which are prepared from 52-54 parts of low-density polyethylene, 33-35 parts of epoxy resin, 27-29 parts of polyvinyl alcohol, 6-8 parts of sodium polyacrylate, 7-9 parts of nanometer titania, and 11-13 parts of egg-shell type nano-catalyst. The high-temperature-resistant medical gloves are easy to prepare, high in high temperature resistance performance and capable of being reused, and accordingly can save a great amount of medical cost and reduce pollution to environment. As modified low-density polyethylene and epoxy resin are mixed and then heated and molten rapidly, grafting between the modified low-density polyethylene and epoxy resin is improved, stability andheat resistance of raw materials are improved, the gloves can bear repeated high-temperature sterilization, and durability of the gloves is improved. Further, with adding of heated sodium polyacrylate and nanometer titania for grafting based on full stirring, film formation property and wear resistance property of the raw materials are improved, and the shaped gloves have smooth surface, and accordingly are not easy to be broken by scraping or be infected crossly by germs.
