Abstract
The invention relates to a preparation method of bottle production resin. The bottle production resin comprises, by weight, 60 parts of PET, 40 parts of PC, 0.4-0.6 parts of tributyl phosphite, 2-5 parts of polypropylene grafted maleic anhydride and 0.5-1 part of dibenzylidene sorbitol. Small amounts of tributyl phosphite and dibenzylidene sorbitol make the PET and the PC be uniformly mixed, crystals be pure and the transparency be increased.
Description
Technical field
The present invention relates to a kind of bottle resin processed, the particularly preparation method of the alloy of a kind of PET and PC。
Background technology
Plastic bottle is mainly by the material such as polyethylene or polypropylene and make after with the addition of multiple organic solvent。It is raw material that plastic bottle widely uses the materials such as polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), after with the addition of corresponding organic solvent, after high-temperature heating, by the mould of plastics plastic containers through blowing, extrusion blow or injection mo(u)lding。It is mainly used in liquid or the solid disposable plastic packing containers such as beverage, food, pickles, Mel, dry fruit, edible oil, agricultural and veterinary chemicals。Plastic bottle has the features such as not broken, with low cost, transparency is high, food grade materials。
Existing PET and PC alloy, transparency is relatively low。
Summary of the invention
In order to overcome the transparent low deficiency of existing PET and PC alloy, the preparation method that the present invention provides the bottle resin processed that a kind of transparency is high。
This invention address that the technical scheme of its technical problem is: a kind of bottle resin processed, including the component of following weight portion: PET60 part, PC40 part, tributyl phosphite 0.4 ~ 0.6 part, polypropylene grafted maleic anhydride 2 ~ 5 parts, Sorbitol are contracted two benzaldehyde 0.5 ~ 1 part。
Increase antibacterial functions, also include nano silver-carrying zirconium phosphate antibacterial 0.1 ~ 0.5 part。
The preparation method of above-mentioned bottle resin processed, comprises the following steps:
A, by PET, PC mix and blend, at 90 DEG C 80 revs/min stirring mixing 10 minutes；
B, by forced air drying 2 hours at 120 DEG C of PET, PC compound through a step；
C, PET, PC compound through b step being added blender, two benzaldehydes that simultaneously tributyl phosphite, polypropylene grafted maleic anhydride, Sorbitol contracted add in blenders, and the lower 60 revs/min of stirring mixing of blender room temperature make ultimate compound in 20 minutes。
D, step c is stirred after ultimate compound add in double screw extruder, 1 district's processing temperature of double screw extruder is 215 DEG C, 2 district's processing temperatures are 220 DEG C, and 3 district's processing temperatures are 225 DEG C, and 4 district's processing temperatures are 230 DEG C, 5 district's processing temperatures are 225 DEG C, 6 district's processing temperatures are 225 DEG C, and head temperature is 220 DEG C, and engine speed is 320 turns/min, check rod after extrusion, dries pelletizing and makes bottle resin processed。
Further, described step c is also placed with in blender nano silver-carrying zirconium phosphate antibacterial。
The present invention in use compared with the bottle resin processed of technology,
The beneficial effects of the present invention is: a small amount of tributyl phosphite and Sorbitol two benzaldehydes that contract make PET and PC mixing more uniform, and crystallization is purer, and transparency increases。
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail。
