Along with the further expansion of urban construction, PE gas line also will be further applied in more in rugged environment, such as, in the low temperature continued, acid or alkali environment, so need the performance further promoting PE gas line, but PE gas line in process of production due to adopt can be different manufacturing process, the assembled watch produced reveals different characteristics, such as splitting resistance.
Summary of the invention
The technical problem to be solved in the present invention is: the PE gas line production method providing a kind of elongation at break high.
For achieving the above object, the invention provides a kind of PE gas line production method, described PE gas line production method comprises the following steps:
Step 1: PE resin-oatmeal 95%-97%, look female 2%-3%, clay nanocomposites 1 ~ 4% are put into drying blendor oven dry together and stirred formation starting material, starting material bake out temperature 60 DEG C-80 DEG C, compounding time continues more than 2 hours, after high temperature mixing, starting material moisture content is less than 0.015%.
Step 2: by the starting material in step 1, drops in shedder and melt extrudes granulation;
Step 3: the granulation material described in step 2 is dropped into forcing machine and extrudes through melting, die orifice, and through cooling trough spraying cooling, obtain PE gas line;
Wherein, the actual temperature on described shedder screw cylinder controls between 175 DEG C-220 DEG C, and head spot temperature controls between 185 DEG C-200 DEG C, and die temperature controls between 190 DEG C-210 DEG C.
Further, described spraying cooling water temperature is between 20 DEG C-40 DEG C, and vacuum pressure is between 0.1-0.8Mpa.
Further, described PE resin-oatmeal is the special mixed ingredients of Borealis HE3490LS.
Further, described clay nanocomposites is phyllosilicate nano material, comprises montmorillonite.
Beneficial effect of the present invention:
The PE gas line that method provided by the invention is produced has good flame retardant resistance, snappiness, low temperature resistant, high temperature resistant, and it is strong that rapid crack increases fracture toughness property, and crushing resistance is good.
