Abstract

The invention discloses a method for preparing a polyethylene material for a medical trachea cannula. The method comprises the steps of 1, preparing all the components by weight; 2, evenly mixing all the components in a mixing and stirring machine; 3, placing evenly mixed materials into a reaction still, heating the reaction still under the vacuum condition to 100-120 DEG C, stirring the materials for 10-20 min, cooling the materials to 30-40 DEG C, stirring the materials for 5-10 min, and obtaining a mixed material; 4, placing the mixed material in a double-screw extruder at a temperature of 180-190 DEG C to obtain sample bars through extrusion, and conducting water cooling, air drying and grain-sized dicing to obtain the polyethylene material. The preparing method is short in process, simple in operation, low in cost, environment-friendly and high in economical effectiveness. Compared with the prior art, the polyethylene material for the medical trachea cannula prepared with the method has the advantage that biocompatibility and safety performance are excellent and better than those of related products existing in the current market.

Description

technical field [0001] The invention belongs to the field of polymer materials and relates to a preparation method of a polyethylene material for medical tracheal intubation. technical background [0002] As a very important material, plastic has been widely used in the medical and health field. It can be made into disposable medical equipment such as drip bottles, syringes, etc., and can be used in non-disposable medical equipment such as gauges, surgical instruments, etc. The field of medical plastics is currently one of the most promising markets in the plastics industry. [0003] With the continuous growth of the global population, especially the aging population and the increase in the number of people suffering from chronic diseases, the continuous growth of the medical service market has been promoted, and special medical devices have been widely demanded. Due to the excellent characteristics of polymer materials and the ability to reduce costs, at present, medical ...
