Description
Technical field
The present invention relates to PET packing container field, be exactly a kind of heatproof PET composite and preparation method thereof andIts purposes.
Background technology
In recent years, due to the good stretch-blow performance of PET and good gas barrier properties, it progressively replaces PE, PP materialBe widely used in the packing containers of beverage, cosmetics. The forming method of PET bottle is mainly divided into one-step method (note stretch blow) and two-step method(stretch-blow), but no matter be one-step method or two-step method, they are all by injection bottle embryo, preheating bottle embryo, stretching, blow moldingTechnique manufacture, all to be preheating to the T of material by the bottle embryo of injectiongAbove just can carry out stretch blow-molded.
Summary of the invention
The present invention aims to provide a kind of heatproof PET composite.
Above-mentioned purpose realizes by following scheme:
A kind of heatproof PET composite, is characterized in that: it is to be made by the raw material of following weight parts:

Described auxiliary agent is made up of the raw material of following weight portion: imvite 15-28, isomery alcohol APEO 1-2, silaneCoupling agent KH5501-3, urea 1.5-2, dolomol 1-3, dimethyl carbonate 2-3, di-n-butyltin dilaurate 1-2, siliconAlgae soil 30-40, aluminium oxide 3.2-4.2, methyl acrylate 1-2;
The preparation method of auxiliary agent puts into calcining furnace by imvite, diatomite to calcine 1-2 hour at 700-800 DEG C,Take out, the hydrochloric acid solution of putting into 10-20% soaks 5-8 hour, filters and takes out, and deionized water washing, dries, be added to the water, thenAdd all the other raw materials, stir, three-roll grinder grinds 1-2 hour, obtains slurry, and spraying is drying to obtain.
Described a kind of heatproof PET composite, is characterized in that: preparation method is:
(1) PET is dried to 3-6h under 120 DEG C of conditions in hot-air oven;
(2) by weight by all raw material blendings, then put into extruding pelletization in double screw extruder, to obtain final product, screw rod turnsSpeed 310-350rpm, temperature setting is set to 240-260 DEG C.
Beneficial effect of the present invention is:
Heat resistance excellence of the present invention, is applicable to use under hot environment, does not discharge noxious material, and environment protection health, to bodyBody is harmless.
