Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a method for preparing medical antibacterial and bactericidal plastics. Background technique [0002] ABS has excellent comprehensive physical and mechanical properties, and excellent low temperature impact resistance. Dimensional stability. Good electrical properties, wear resistance, chemical resistance, dyeability, finished product processing and mechanical processing. ABS resin is resistant to water, inorganic salts, alkalis and acids, insoluble in most alcohols and hydrocarbon solvents, but easily soluble in aldehydes, ketones, esters and some chlorinated hydrocarbons. ABS resin has a low heat distortion temperature, is flammable, and has poor heat resistance. The melting temperature is 217~237°C, and the thermal decomposition temperature is above 250°C. Many of the modified ABS materials on the market today are mixed with nozzle materials and recycled material...
