Embodiment 1

[0043] The proportioning ratio of each component is (total amount is 100kg):

[0044]

Embodiment 2

[0046] The proportioning ratio of each component is (total amount is 100kg):

[0047]

Embodiment 3

[0049] The proportioning ratio of each component is (total amount is 100kg):

[0050]

[0051]Under normal temperature and pressure, prepare 100kg micro-foaming universal white masterbatch. The preparation process is as follows: after mixing the components in proportion, pre-mix the components in the mixer for 5 minutes at a low speed, and then mix them at a high speed for 15 minutes. Finally, the fully mixed materials are melt-blended in a twin-screw extruder, the temperature is controlled at 200°C, and the screw speed is 200r / min. The pigment is uniformly dispersed in the carrier resin through shearing and mixing of the screw, and then the manufacturing process is carried out. The color masterbatch of the present invention is obtained through the processes of granulation, drying, packaging and the like.

[0052] In order to compare the advantages of the present invention and the prior art, comparative experiments are carried out according to the formulations of the compar...

Abstract

The invention discloses a general white master batch and its preparation method. The general white master batch is made from the following components of: by weight, 16-23% of a carrier resin; 50-75% of a pigment; 0-3% of a processing aid; 0-2.5% of a heat stabilizer; 4-7% of a dispersant; 0.1-3% of a coupling agent; and 0-40% of a filler. The general white master batch has good dispersibility and high whiteness, can be used for the coloring of a plurality of plastics such as polyethylene, polypropylene, polystyrene, high impact polystyrene, acrylonitrile-butadiene-styrol copolymer and the like, and has good compatibility with the colored plastics. Final products have no flow feeder liner, have high whiteness and have excellent impact performance. The general white master batch is especially applicable for white household electrical appliances which have high requirements on whiteness and surface glossiness.

Description

[technical field] [0001] The invention relates to the field of plastic coloring, in particular to a general-purpose white masterbatch and a preparation method thereof. [Background technique] [0002] There are three methods of plastic coloring: toner coloring, dyeing coloring, and masterbatch coloring. Direct toner coloring is very simple, but there are disadvantages such as color point, color difference, and production environment pollution. The coloring effect of dyeing and granulation is better than that of toner, but the cost is high and the performance of the material will decrease after heat treatment. The pigment is pre-dispersed and evenly dispersed in the carrier resin, which greatly improves the dispersibility and coloring efficiency of the pigment, and has low cost and no pollution to the environment. [0003] Due to the variety of colors in plastic coloring, different materials have different requirements for color masterbatches, resulting in a wide variety of ...
