Technical field
The present invention relates to packaging material field, and in particular to a kind of transparent plastic anti-theft bottle cap.
Background technology
Polypropylene (PP) is the highly crystalline polymer of nontoxic, odorless, tasteless milky, with light weight, inexpensive, health,
The advantages of high temperature resistant, easy processing molding, automobile making, household electrical appliance, articles for daily use and packaging material etc. have been widely used in it.
But because the polyacrylic crystallization rate slower processing and forming cycle is long, low temperature impact properties are poor, product gloss and the transparency are not
It is good.
Polypropylene transparent is mainly affected by reflecting and scatter, and folding is produced to light because polyacrylic spherulite size is big
Penetrate, the virgin pp transparency is poor.Add after nucleator in polypropylene, nucleator can be as out-phase core prior to poly- third
Alkene melt crystallization, forms finely dispersed fibrous grid, and the surface of the grid is crystallization nucleation center, improves nucleation close
Degree, the spherocrystal for making generation is uniformly refined, and when wavelength of the spherulite size less than visible ray light wave, light just can directly pass through, from
And improve polyacrylic transparent performance.Therefore it is to realize high performance, high transparency to be modified using Nucleating Agent on Pp
Simple and effective method.
Nucleator can be divided into mineral-type, phosphate metal salt, carboxylic acid metal's salt and Sorbitol Nucleator.Wherein without
Machine class, phosphate metal salt and the nucleater modified effect of carboxylic acid metal's salt be not very good.And Sorbitol Nucleator bag
Dibenzal sorbitol that is unsubstituted and replacing is included, substituent group can be alkyl, alkoxyl, halogen etc., wherein unsubstituted dibenzyl
Fork Sorbitol antireflective effect is also undesirable and unstable at high temperature, and the dibenzal sorbitol class nucleator for replacing is for poly-
Propylene has preferable antireflective effect, but great majority have the penetrating odor of free aldehyde, make product in food, beverage packaging etc.
The application in field is restricted, such as the use of the nucleator in beverage bottle cap is just restricted, in addition, bottle in prior art
Lid is that, by lid machine compression molding, and there is capping machine itself certain technological temperature to limit (normally no higher than 220 DEG C), form
Core agent will affect processing temperature with the polyacrylic compatibility, although existing third generation Sorbitol Nucleator antireflective effect it is good and
Free from extraneous odour, but with polyacrylic optimal process temperature often beyond 220 DEG C, this respect also limit nucleator in plastic bottle
Application in terms of lid processing, above-mentioned various factors causes that beverage bottle cap transparency on the market is not high, and outward appearance lacks aesthetic feeling, is full
Sufficient transparency is high and the market demand of plastic bottle closure of safe free from extraneous odour, is badly in need of proposing new technical scheme.
The content of the invention
Therefore, for the not high technical problem for having an abnormal flavour of transparency of plastic bottle closure of the prior art, the mesh of the present invention
Be to provide that a kind of transparency is high and transparent plastic anti-theft bottle cap of free from extraneous odour.
The raw material of the transparent plastic anti-theft bottle cap of the present invention includes homopolymerization PP and nucleator Millad NX8000, with quality
Number meter, homopolymerization PP and nucleator Millad NX8000 proportionings are 100：0.10～0.20.

Preferably, homopolymerization PP and nucleator Millad NX8000 proportionings are 100：0.15.
Millad NX8000 are the nucleator of new generation of Milliken chemistry (Milliken Chemica1) company exploitation,
And avirulence good with the homopolymerization PP compatibility, its optimal process temperature is 190-220 DEG C, in the technique of existing capping machine compression molding
In the range of, and molding cycle is shorter, transparent effect is significantly and flexibility (adaptability) of operation is stronger.
The present invention also attempts preparing plastics as nucleator using the Millad 3988 of antireflective effect significantly good and free from extraneous odour
Pilfer-proof closure.But, because Millad 3988 is relative with the homopolymerization PP compatibility poor, the dispersion effect of requirement is reached, it is optimal to add
Work temperature is 220-240 DEG C, and not only energy consumption is higher, and has exceeded the technological temperature of existing capping machine compression molding, it is impossible to make
With the direct compression moulding processing of existing capping machine, so it is not appropriate for the additive as plastic bottle closure.
Another object of the present invention is to provide a kind of method for preparing transparent plastic anti-theft bottle cap, it includes step：
A, homopolymerization PP and nucleator Millad NX8000 are mixed in proportion；
B, the mixture for obtaining step A melt temperature be 180～220 DEG C and briquetting pressure be 140-180bar
Under the conditions of, after double screw extruder is extruded, Jing capping machines are compression molded into antitheft plastic cap of bottle.
Preferably, the melt temperature of the mixture is 190 DEG C, and briquetting pressure is 155bar.
Beneficial effects of the present invention：The present invention with the special homopolymerization PP of bottle cap as raw material, and by addition and homopolymerization PP phase
Capacitive is good and avirulent nucleator Millad NX8000 come anti-reflection modified, and the nucleator can not only make the special homopolymerization PP of bottle cap
With good nucleation efficiencies and excellent anti-reflection modified effect, make obtained transparent plastic bottle cap transparency high, it is specious,
