preparation example Construction

[0024] The preparation method of a kind of titanium dioxide masterbatch provided by the present invention comprises the following steps:

[0025] (1) Raw material preparation: carrier resin 20-60%, titanium dioxide 30-70%, dispersant 1-6%, antioxidant 1-4%;

[0026] (2) Mixing: Utilize a high mixer to mix the dispersant and antioxidant uniformly in proportion to obtain mixed powder;

[0027] (3) Extrusion granulation: use an extruder to mix the carrier resin, titanium dioxide and the mixed powder obtained in step (2) according to the proportion through a weight loss scale, and then extrude granulation. The screw speed of the extruder is 280-300 rpm, and the temperature of the extruder is set at 200°C-295°C.

[0028] The antioxidant used in the embodiment is a mixture of antioxidant 1010 and antioxidant 168, wherein the weight ratio of antioxidant 1010 to antioxidant 168 is 1:1.

Embodiment 1

[0031] The titanium dioxide pink masterbatch and the preparation method thereof provided by the present invention, the titanium dioxide pink masterbatch comprises the following components: 40% of PET carrier resin, 50% of rutile titanium dioxide, 6% of polyethylene wax, and 4% of antioxidant . The preparation method of titanium dioxide pink masterbatch is to automatically feed the material according to the proportion through the weight loss scale. The extruded strips are water-cooled, dried, pelletized and packaged to obtain titanium dioxide pink masterbatch.

Abstract

The invention relates to the field of plastic coloring and in particular to titanium dioxide masterbatch and a preparation method thereof. In order to solve the problem that existing white masterbatch is relatively poor in compatibility with PET, the invention provides the titanium dioxide masterbatch and the preparation method thereof. The titanium dioxide masterbatch comprises the following raw materials in percentages by weight: 20-60% of carrier resin, 30-70% of titanium dioxide, 1-6% of a dispersant and 1-4% of an antioxidant. The titanium dioxide masterbatch provided by the invention has the advantages of being strong in coloring ability and good in dispersibility and good in compatibility with PET. The preparation method of the titanium dioxide masterbatch provided by the invention is simple in process and suitable for scaled production.

Description

technical field [0001] The invention relates to the field of plastic coloring, in particular to a titanium dioxide pink masterbatch and a preparation method thereof. Background technique [0002] Color masterbatch usually consists of three elements: carrier resin, pigment and additives. Among them, the pigment is the core, and the performance of the pigment plays a decisive role in the performance of the masterbatch. Titanium dioxide has strong hiding power and high whiteness, and is the first choice for white masterbatch pigments. PET (polyethylene terephthalate) has excellent heat resistance, corrosion resistance, toughness, electrical insulation, etc., and is cheap, so it is widely used in plastic fields such as fibers, films, and polyester bottles. A large part of PET needs to be used for coloring, but PET coloring is relatively difficult, and the compatibility of the white masterbatch used now with PET is poor.
