preparation example Construction

[0060] The preparation method of the extra-black high-gloss wear-resistant polyamide resin of the present invention comprises the following steps:

[0061] (1), prepare nigrosine master batch;

[0062] (2), mixing polyamide, molybdenum disulfide, nigrosine master batch, polyethylene wax, modified silane meshing material and filler in a mixer to obtain a mixture;

[0063] (3), adding the mixture into a twin-screw extruder for extrusion, and dicing to obtain an extra-black high-gloss wear-resistant polyamide resin.

[0064] Wherein, in step (1), nigrosine master batch is obtained by mixing 85-90wt% nylon 6, 9-13wt% oil-soluble nigrosine and 1-2wt% dispersant for 5-8min and extruding, and the dispersant is vinyl Distearate. The extrusion process is as follows: the temperature of the first zone is 180-220°C, the temperature of the second zone is 190-230°C, the temperature of the third zone is 200-250°C, the temperature of the fourth zone is 200-250°C, and the temperature of the ...

Abstract

The invention provides an extra-black high-gloss wear-resistant polyamide resin, a preparation method and application thereof. The polyamide resin includes polyamide, modified silane mesh, nigrosine master batch, molybdenum disulfide, polyethylene wax and filler. The preparation method is as follows: firstly, the nigrosine master batch is obtained by mixing and extruding 85-90wt% nylon 6, 9-13wt% oil-soluble nigrosine and 1-2wt% dispersant; then polyamide, molybdenum disulfide, aniline Black master batch, polyethylene wax, modified silane meshing material and filler are mixed to obtain a mixture, and the mixture is added into an extruder for extrusion, and then diced; the present invention adds nigrosine master batch and polyamide with a specific content compound, so that the polyamide resin has a good and darker color; the present invention adds molybdenum disulfide, so that the polyamide resin has better wear resistance; the present invention adds polyethylene wax and modified silane, so that the polyamide The resin has good surface gloss and processing properties.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an extra-black high-gloss wear-resistant polyamide resin and a preparation method and application thereof. Background technique [0002] Polyamide is colored with ordinary carbon black. Due to the poor dispersibility of carbon black, the surface is prone to pitting and white spots. At the same time, the addition of carbon black will cause the surface gloss to decrease. Generally, the L value of the color can only be 4- 5. In the high-gloss spray-free products, the aesthetic effect of high gloss and high black is pursued. Generally, the gloss is around 90. At the same time, certain wear resistance is required. The general wear-resistant gray level is level 3. It is currently difficult to achieve such a high-gloss black and wear-resistant product on the market. SUMMARY OF THE INVENTION [0003] In view of the deficiencies in the prior art, the primary purpo...
