Embodiment 1

[0023] A high-black high-gloss black masterbatch, comprising the following components by weight:

[0024] Carbon black BP71750%,

[0025] Low-density polyethylene LDPE-1C7A14.2%,

[0026] Linear low density polyethylene LLDPE-2650 19.09%,

[0027] Polyethylene wax AC-6A11.54%,

[0028] Lubricant wax H-50S4.67%,

[0029] Antioxidant AO-500.5%.

[0030] A preparation method of high-black and high-brightness black masterbatch, comprising the following technological process:

[0031] Stirring - banburying - granulation - dehydration - encapsulation.

[0032] The stirring refers to sequentially mixing linear low density polyethylene LLDPE-2650, polyethylene wax AC-6A, slip wax H-50S and antioxidant AO-50 at 19.09%, 11.54%, 4.67% and 0.5% Put the ratio into a high-speed mixer for stirring, the stirring time is 10 minutes, the stirring temperature is 60°C, and then wait for 1 hour to obtain the mixture a.

[0033] The banburying refers to the low density polyethylene LDPE-1C7A...

Embodiment 2

[0037] Plastic Modification Test

[0038] Taking the resin PC and PC / ABS as examples respectively, the effects of the black masterbatch BKE-2501 obtained in Example 1 and the existing black masterbatch 1064 on the market on the physical properties of the modified plastic are studied. The test results are shown in the table below :

[0039]

[0040] Analysis of test results: It can be seen from the above table that adding 5% of BKE-2501 has less effect on the physical properties of resin PC and PC / ABS than adding 5% of 1064; The value of the yellow-blue axis B is small, and the blue phase is high.

Abstract

The invention relates to high-blackness high-brightness black master batch and a preparation method thereof. The high-blackness high-brightness black master batch comprises the following ingredients by weight: 50 percent of carbon black BP717, 14.2 percent of low-density polyethylene LDPE-1C7A, 19.09 percent of linear low-density polyethylene LLDPE-2650, 11.54 percent of polyethylene wax AC-6A, 4.67 percent of lubricant wax H-50S, and 0.5 percent of an antioxygen AO-50. The preparation method comprises the following processes: stirring, mixing, granulating, dewatering and packing. Compared with the prior art, the high-blackness high-brightness black master batch is low in impact on a plastic material to-be-modified, and easy to dilute in a plastic product, and has the advantages of high blackness, high blue phase, high brightness, and excellent dispersity, thereby having high popularization value.

Description

technical field [0001] The invention relates to a color masterbatch and a preparation method thereof, in particular to a high-black and high-brightness black masterbatch and a preparation method thereof. Background technique [0002] Masterbatch is a new type of special colorant for polymer materials. It usually consists of three basic elements: pigment, carrier and additives, and is used for the dyeing of plastic products. [0003] Black masterbatch is the most commonly used color masterbatch in plastic processing. It is a plastic colorant that is well dispersed with a high proportion of pigments or additives and thermoplastic resins. The selected resin has good lubricity to the colorant. Wet and disperse, and have good compatibility with the material to be colored. It is widely used in plastic processing industries such as injection molding, extrusion molding and blow molding. [0004] Plastic modification is to improve or increase the functions of large quantities of ge...
