The product has the beneficial effects of stable color, excellent performance, easiness in processing and good surface gloss.

Description

A kind of PA6 mixture with stable tinctorial property and preparation method thereof
Technical field
The present invention relates to a kind of PA6 matrix material, be specially a kind of PA6 mixture with stable tinctorial property and preparation method thereof, belong to polymer composite field.
Background technology
It is to use as chemical fibre that PA6 resin starts most, but because it has excellent processing characteristics and mechanical property, is applied to widely the industries such as automobile, electronic apparatus as engineering plastics.
Along with going deep into of PA6 resin application, the tinctorial property of PA6 requires more and more higher.Because PA6 is as hypocrystalline engineering plastics, processing temperature is high, can be used for the toner kind of dyeing limited, adds that the PA6 mobility of molten state is fine, causes with the bond properties of toner poorly, often occurs the phenomenon of aberration or color shakiness.
Based on this reason, related personnel has carried out a lot of research.Noriyoshi Watanabe improves the retention of color of PA66 in USP.5412013 by mantoquita, aramid fiber; Gerardus P.T.Vonk is less than 20% PA6 at USP.5674968 middle-end amino and improves retention of color; Rolando Umali Pagilagan etc. adds nylon to and improves colour stability in synthetic with phosphoric acid salt at USP.6191251.
By oxidation inhibitor and other auxiliary agents, can promote the painted stability of PA6, but in actual applications, color is unstable or often occur, and illustrate that simple these auxiliary agents of interpolation can not address this problem completely.
Summary of the invention
Goal of the invention of the present invention is for a kind of PA6 mixture with stable tinctorial property is provided, to reduce the colour-change of even eliminating in injection moulding process.
Another object of the present invention is for the preparation method of above-mentioned matrix material is provided.
