Problems solved by technology

The content of this kind of white masterbatch titanium dioxide is more than 40%, which will easily lead to a large proportion of color masterbatch
The color masterbatch is easy to sink during mixing with plastics and post-molding, resulting in uneven color dispersion
At the same time, the price of titanium dioxide is higher, resulting in higher production cost of masterbatch

Embodiment 1

[0012] Under normal temperature and pressure, the following components and weight percentages: PS 40%, polyethylene wax 10%, glass microspheres 50%, were mixed in a high-speed mixer for 10 minutes at a high speed, and a twin-screw extruder was used for melting and co-mixing. Mixing, the temperature is controlled at 200°C, the screw speed is 200r / min, the pigment is uniformly dispersed in the carrier resin through the shearing and mixing of the screw, and then the strands are cut into pellets (the appearance of the masterbatch is cylindrical), dried, Packing to obtain the color masterbatch of the present invention.

Embodiment 2

[0014] Under normal temperature and pressure, mix the following components and weight percentages: PS 20%, polyethylene wax 5%, glass microspheres 75%, and mix them in a high-speed mixer. Strand cutting (the appearance of the color masterbatch is a square sheet) is carried out to obtain the color masterbatch of the present invention.

Abstract

The invention discloses a masterbatch, which is composed of the following components by weight percent: 40-75% of glass microspheres, 1-20% of a dispersing agent, and 20-45% of carrier resin. The masterbatch of the invention has little influence on impact performance of materials, can enhance the flowing property of color concentrate and promote masterbatch dispersion in HIPS (high impact polystyrene).

Description

technical field [0001] The invention relates to the field of high-impact polystyrene (HIPS) coloring, in particular to a white masterbatch used for HIPS coloring. Background technique [0002] At present, the newly developed high-impact polystyrene is close to ABS and other engineering plastics in some properties. And with the improvement of HIPS function, more and more HIPS are used instead of ABS resin in electronic and electrical industries such as televisions, copiers, air conditioners, and refrigerators. [0003] Color masterbatches are often used for coloring in HIPS production and processing, among which white masterbatch is the most important and widely used one. The HIPS white masterbatch currently on the market is usually made of titanium dioxide, processing aids and carrier resin mixed and granulated in a certain proportion. The content of this kind of white mother titanium dioxide is more than 40%, which will easily lead to a large proportion of color masterbat...
