Problems solved by technology

However, the existing pearlescent color masterbatches still have relatively large deficiencies in organic pigment dispersion and pearlescent texture.
[0003] The poor dispersion effect of organic pigments will not only lead to poor dispersion of pearlescent masterbatch and low coloring strength, but also cause irregular color points in plastic products
[0004] The existing pearlescent color masterbatch is basically mixed by high-speed mixer. High-speed mixing will greatly damage the particle size of pearlescent powder, affect the pearlescent texture, and the color and permeability of the colored plastic products are not good.
[0005] Although there are also literature reports (see Chinese patent documents CN101392077A and CN104312109A) that other materials can be mixed at high speed first, and then mixed with pearlescent powder at low speed, but this technical means has limited improvement in pearlescent texture and has little effect on the dispersibility of organic pigments.

Embodiment 1）

[0037] The preparation method of the masterbatch compound of the present embodiment is specifically as follows:

[0038] ① Preparation of high-concentration single-color masterbatch.

[0039] Add 4.2kg of LLDPE resin, 2.52kg of organic pigments and 0.28kg of polyethylene wax into a continuous internal mixer (sourced from Farrell, USA), and continuously banbury at a temperature of 185±2°C for 3 to 5 minutes , and then granulated to obtain 7kg high-concentration single-color masterbatch.

[0040] The concentration of the organic pigment in the high-concentration single-color masterbatch is 36wt%.

[0041] The organic pigment used in this embodiment is C.I. Pigment Yellow 17.

[0042] ② Preparation of low-concentration single-color masterbatch.

[0043] Mix 7kg of high-concentration single-color masterbatch prepared in step ① with 28kg of LLDPE resin, then add it to a single-screw extruder, extrude and knead, strand water-cooled, and pelletize to obtain 35kg of low-concentrati...

Abstract

The invention discloses a color masterbatch mixture and a preparation method thereof. The color masterbatch mixture is made of polyolefin resin, toner, polyethylene wax and organic pigments. Olefin resin and polyethylene wax are processed to obtain high-concentration monochrome masterbatch, and then diluted with polyolefin resin to obtain low-concentration monochrome masterbatch, and finally processed with polyolefin resin, toner and polyethylene wax to obtain color masterbatch. compound. The method of the present invention can finally produce a color masterbatch compound with high coloring strength and good dispersion, which can produce excellent color permeability when applied to the coloring of plastic products, and is suitable for medium and high-grade polyolefin plastic products coloring processing.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a color masterbatch compound and a preparation method thereof. Background technique [0002] Pearlescent color masterbatch is widely used in plastic processing because of its excellent special texture. However, the existing pearlescent color masterbatches still have relatively large deficiencies in organic pigment dispersion and pearlescent texture. [0003] The poor dispersion effect of organic pigments will not only lead to poor dispersion of pearlescent masterbatch and low coloring strength, but also cause irregular color points in plastic products. [0004] The existing pearlescent color masterbatch is basically mixed with a high-speed mixer. High-speed mixing will greatly damage the particle size of the pearlescent powder, affecting the pearlescent texture, and the color permeability of the colored plastic products is not good. [0005] Although there...
