Abstract
The present invention relates to a transparent polypropylene composite, said composite contains 100 portions of polypropylene, 0.05-6 portions of trasparent agent and 0.05X10 to the minus sixth-3X10 minus sixth anthraquinone disperse dye. Said composite is made up by using the above-mentioned all the material, mixing them according to a certain proportion uniformly, melting them at 180-240 deg.C, extruding by using twin-screw extruder and granulating the obtain the finished product.
Description
Technical field
The present invention relates to a kind of transparent polypropylene composition, particularly relate to a kind of transparent polypropylene composition with good surface appearance form and aspect.
Background technology
Existing transparent polypropylene composition production is generally and adds the glucitols transparent nucleater in polypropylene.Owing to multiple reason, the transparent polypropylene of producing often exists not enough at aspects such as outward appearance form and aspect now.For example outward appearance jaundice, the yellowing of goods color, color and luster, glossiness is bad, transparency is inhomogeneous etc.
In recent years, reported a kind of technology (seeing " printing during chemical industry " 1999 the 6th phase 29-30 pages or leaves " pigment dyestuff improves the research of polypropylene transparent as nucleator " literary composition) of improving polypropylene transparent and form and aspect with the phthalocyanines pigment dyestuff as nucleator.But the phthalocyanines pigment dyestuff coloured light that this technology is used mostly is ruddiness, blue or green light or purplish red light, and from the colorimetry principle, blue light, purple light are only the absorb light of yellow-green light.Therefore after using the phthalocyanines pigment dyestuff, when eliminating polypropylene material yellowing phenomenon, often having the residual of red partially or inclined to one side green light, cause visual effect good inadequately, also is that form and aspect are good inadequately.
Summary of the invention
The object of the present invention is to provide a kind of outward appearance form and aspect of having improved transparent polypropylene preferably, solved the transparent polypropylene composition of existing transparent polypropylene goods yellowing phenomenon.
The present invention uses the dispersed dye of anthraquinone ring to improve polypropylene transparent and form and aspect, and the dispersed dye of anthraquinone ring have the characteristics of steady chemical structure, color light stabilizing, and its coloured light is purplish blue light, just the absorb light of yellow-green light.Use these dispersed dye in transparent polypropylene composition after, eliminate the yellowing phenomenon fully, and make the outward appearance of goods more apparent clean and clear transparent, visual effect is better.
Specifically, the invention provides a kind of polypropene composition, it comprises following composition: 100 parts of acrylic resins (A); 0.05～0.6 part of transparent base (B); 0.05 * 10

Embodiment
Below, with the invention will be further described with Comparative Examples in conjunction with the embodiments.But the present invention is not subjected to the restriction of embodiment content.
Embodiment 1～10 and Comparative Examples 1～9:
Table 1, table 2, table 3 are listed the addition of above-mentioned each component A～C in each embodiment and Comparative Examples respectively.Each component of A～C under 180 ℃～240 ℃ conditions of processing temperature, behind the uniform mixing, is adopted the screw extrusion press extruding pelletization, obtain granular polypropene composition, test its performance according to ordinary method then: the test yellowness index adopts GB2409-80; The test mist degree adopts GB2410-80, adopts the mold pressing film-making, sheet thick 1 millimeter (mm).Test result is also listed in the table.
Yellowness index is a kind of index of estimating plastic quality.According to the measured yellowness index of GB2409-80 and under sun exposure observed yellow degree can coincide preferably, thereby can be used to estimate plastic quality.
According to the measured yellowness index of this law, on the occasion of representing that then material is yellow, negative value represents that then material is blue in this way in this way.
Mist degree is to depart from the scatter light flux of incident light direction and the ratio of transmitted light flux through sample, represents with percentage ratio.
Haze value is big more, and the transparency of material is poor more, otherwise haze value is more little, and the transparency of material is good more.
