Problems solved by technology

[0003] Most of the conventional flow effect materials on the market are PP / PE or PC / ABS products, PP / PE materials are soft and prone to stress whitening items, while PC / ABS lacks gloss on the surface
Nylon has the advantages of good toughness and high gloss, but there are few nylon flow pattern products on the market

Abstract

The invention discloses a PA6 / PA56 flow liner silver apparent material which is prepared from the following raw materials in parts by weight: 4-19 parts of a PA6 white dyeing material and 1 part of a PA56 silver master batch. The PA6 resin has high flowability and certain surface gloss due to material characteristics, the high-temperature PA56 is softened and dispersed in the low-temperature PA6 by manufacturing two dyeing materials with different colors and utilizing different melting points of the two materials PA6 and PA56, the high-temperature PA56 is oriented in the ejection direction and is in a flow liner shape, the material cost is low, and the material can be applied to elevator decorative plates, storage boxes and the like to replace traditional plastic paint spraying parts.

Description

technical field [0001] The invention belongs to the technical field of engineering plastic alloys, and more specifically relates to a PA6 / PA56 rhyolite silver appearance material and a preparation method thereof. Background technique [0002] PA6 is polyamide 6, which is an organic substance with a chemical formula of C 6 h 11 NO, PA56 is Nylon 56. To make a material with a flow pattern effect, two or more materials with different melting points and good compatibility are usually required. If the compatibility of the two materials is not good, the surface will peel And the material performance is very poor. Therefore, if you want to make a material with a good flow pattern effect, you need to have a certain difference in melting point temperature between the two materials, and you must also avoid the large difference in melting point that will cause the high-temperature components to not melt. If the processing temperature is higher, the two materials If they are all melt...
