Parison；
(2) molten parison is put into inflation in the injection mold of milk bottle to form, the movement for blowing bottle includes: molding → sealing
→ put bar → air blowing → and be vented → begin to speak → rising stem → die sinking；
(3) cooling and shaping is carried out to inflation milk bottle after molding；
(4) qualification is taken out from injection mold and checked whether to the milk bottle after cooling and shaping, qualified repairs except edge grinding,
Underproof rejecting；
(5) it will repair except the qualified milk bottle after edge grinding carries out washing printing design；
(6) milk bottle after washing printing design will be carried out to be packed and stored.
The modified titanium is by titanium dioxide, tetrabutyl ammonium fluoride and polyethyleneimine according to mass ratio 15-20:7:1
Ratio after mixing, be again heated to after tetrabutyl ammonium fluoride is completely melt, stir evenly obtained.
The anti-blushing agent is that Myrj 45 and polycaprolactam powder are added into ball mill, ball-milling treatment
It is made after 50-70min.
The nano antibacterial agent is one of nano zine oxide, nano-titanium dioxide and nano silica or a variety of.
At 160-190 DEG C, negative pressure of vacuum reaches 0.6MPa or more for the temperature control of extruder in the step (1).
The beneficial effects of the present invention are: the modified titanium added in inventive formulation can not only prevent titanium dioxide from using
Oxidative phenomena occurs in the process, moreover it is possible to improve the compactness of plastic milk bottle；The anti-blushing agent of addition makes plastics ox obtained
Feeding bottle is not easy to change, extends the service life of plastic milk bottle；And the plastics that the blowing technology used in the present invention is blown
Milk bottle uniform wall thickness, intensity is high, bottoms split seam, and production efficiency is higher.
