| titleOfInvention | A kind of preparation method of trachea cannula pvc material |
| abstract | The present invention provides a kind of preparation method of trachea cannula pvc material, first take polyvinyl chloride, phenolic resin, polypropylene glycerol aether, ethylene propylene copolymer, dioctyl phthalate, acetyl citrate, zinc oxide, pine tar, precipitated calcium carbonate, thiol methyl tin, hexamethylene 1, 2 dicarboxylic acid anhydrides, epoxidized soybean oil, plasticizer, it adds in mixing and blending machine and is stirred, gained mixture is heated to 90~100 DEG C under nitrogen protective condition, keep the temperature 20~30min, again 15~20 DEG C are cooled to the speed of 20 DEG C/min, keep the temperature 10~15min, obtain prefabricated powder, finally prefabricated powder is squeezed out in double screw extruder.The pvc material tensile strength is that 40.3,180 DEG C of stability reach 49min in 23.95MPa, elongation at break 228%, shore hardness A, has good mechanical property, the transparency, cold resistance and stability. |
