[0025] Such as figure 1 As shown, the present invention provides a nylon 6 colored slice, comprising: an outer layer 1, an inner layer 2, and colored particles 3, the outer layer 1 and the inner layer 2 are closely connected, and the colored particles 3 are in the inner layer 2.

[0026] Wherein, the inner layer 2 is red nylon 6 slices.

[0027] Wherein, the outer layer 1 is nylon 6 slices.

[0028] Wherein, the colored particles 3 are red particles.

[0029] Wherein, the ratio range of the cross-sectional diameters of the outer layer 1 and the inner layer 2 is 1:2.

[0030] Wherein, the cross-section of the slice is rectangular.

[0031] Wherein, the percentage range of the mass of the colored particles 3 to the mass of the inner layer 2 is 0.02%.

[0032] The present invention also provides a method for manufacturing nylon 6 colored slices, the steps are as follows:

[0033] 1) The coloring agent, nylon 6 slices and dispersant are proportioned; the coloring agent is red...

Embodiment 2

[0039] Such as figure 1 As shown, the present invention provides a nylon 6 colored slice, comprising: an outer layer 1, an inner layer 2, and colored particles 3, the outer layer 1 and the inner layer 2 are closely connected, and the colored particles 3 are in the inner layer 2.

[0040] Wherein, the inner layer 2 is blue nylon 6 slices.

[0041] Wherein, the outer layer 1 is nylon 6 slices.

Abstract

The invention provides a polyamide-6 colored granula and further provides a preparation method thereof. The polymide-6 colored granula comprises an outer layer, an inner layer and colored particles, wherein the outer layer is connected with the inner layer closely, the colored particles are disposed in the inner layer, the inner layer refers to the colored polyamide-6 granula, the outer layer refers to polyamide-6 granula, the proportional region of diameter of cross sections of the outer layer and the inner layer is between 1:8 to 8:1, the cross section of the granula can be rectangle, oval,circle or triangle, and the mass percent of the colored particles to the inner layer ranges from 0.02% to 5%. The polymide-6 colored granula has the advantages that as the colored particles are disposed in the inner layer, the granula is not affected by a follow-up process for dyeing the same of white or light color.

Description

technical field [0001] The invention relates to the field of nylon, in particular to a nylon 6 colored slice and a manufacturing method. Background technique [0002] The chemical and physical properties of nylon 6 are very similar to nylon 66, however, it has a lower melting point and a wide range of process temperatures. Its impact resistance and solvent resistance are better than nylon 66 plastic, but it is also more hygroscopic. [0003] At present, nylon 6 slices are generally milky white and transparent. Nylon 6 colored slices are evenly distributed in color, and the visual effect is better than ordinary slices. Contents of the invention [0004] The object of the present invention is to provide a nylon 6 colored chip, which has the advantages of simple structure and wide application range. [0005] In order to achieve the above object, the present invention provides a nylon 6 colored slice, comprising: an outer layer, an inner layer, and colored particles, the out...
