Abstract
This invention relates to preparation method of a transparent polypropylene, which takes nano silicasol and organophosphate type polypropylene nucleating agent as materials. Mix the nanometer silicasol and organophosphate type polypropylene nucleating agent and polypropylene by weight ratio of 0.05- 1: 0.1- 1: 100 at 160 to 230deg C.
Description
Technical field
The present invention relates to a kind of preparation method of transparent polypropylene, particularly a kind of preparation method with Nano silica sol and the composite preparation transparent polypropylene of organophosphate type polypropylene nucleater.
Background technology
Polypropylene is a class excellent property, low price, of many uses, translucent crystalline plastics, can improve the polyacrylic transparency by adding nucleator, obtains the transparent polypropylene plastics.The transparent nucleator for polypropylene of Xiao Shouing mainly contains Sorbitol Powder, organophosphate and rosin acids polypropylene nucleater in the market, but they in various degree have a price height, peculiar smell is arranged, shortcomings such as bad dispersibility.Organophosphate is the polyolefine transparent nucleator of the increasingly extensive application behind benzylidene sorbitol and derivative thereof, these products mainly be organophosphate metal-salt and phosphoric acid ester basic metal salt and compound thereof or with the mixture of phosphoric acid ester, acid phosphoric acid ester, also can be divided into 3 generation product.The 1st generation was representative with the electrochemical NA-10 of the rising sun: the 2nd generation was the phosphoric acid salt of 20th century structure of bisphenol A released of the mid-80, as NA-11 (2-2 '-methylene radical-two-(4,6-two trimethylphenylmethane bases)) sodium phosphate; The 3rd generation was the NA-21 that develops in recent years.Compare with DBS and derivative thereof, when organophosphate series nucleator is used for PP, the goods transparency, rigidity, crystallization velocity and heat-drawn wire have raising by a relatively large margin, and have obtained the U.S. FDA approval, and excellent heat resistance, can anti-high temperature more than 400 ℃, the processing conditions range of choice is wide, does not decompose in moulding process and can not discharge niff, simultaneously, also less generation can be used for food product pack to the pollution of forming machine and screw rod.Although cost an arm and a leg, unique application performance is its advantage, and its main drawback is that fusing point is too high, and is limited with the consistency of resin, is difficult for being mixed under the bad dispersibility, usual conditions.The objective of the invention is to overcome the above-mentioned shortcoming of nucleator in organic phosphate class, utilize reactive extrusion technology simultaneously, make silicon sol in extrusion, form nano silicon, thereby change nano silicon shortcoming such as bad dispersibility, transparent DeGrain in polypropylene.
Summary of the invention
The preparation method of a kind of transparent polypropylene of the present invention is, is 0.05～1: 0.1～1: 100 by weight with Nano silica sol and organic phosphate transparent nucleator for polypropylene and polypropylene, and mixing at 160 ℃～230 ℃.
The Nano silica sol that the present invention uses, odorless, nontoxic, molecular formula can be expressed as mSiO
2.nH
2O, colloid median size 10-20nm.Be difficult for the dispersive problem in order to solve organic phosphate nucleating agent, select for use silicon sol and organophosphate to carry out composite system, experimental results show that to have obtained composite preferably effect, and nanometer SiO
2Particulate and organic phosphate nucleating agent have been brought into play effective synergy, can further reduce the mist degree of PP, improve its transparency.The addition of silicon sol content in polypropylene is 0.05～5%, is preferably in 0.05～1%.Positively effect of the present invention 3 Comparative Examples described as follows.
