Abstract

The invention discloses an anti-ultraviolet environment-friendly color master batch and a preparation method thereof. The anti-ultraviolet printing ink is prepared from the following raw materials: pigment, carrier resin, a dispersing agent, a coupling agent, a processing aid, an anti-ultraviolet stabilizer, a fluorine-containing polymer and low-molecular-weight polypropylene, the preparation method comprises the following steps: sequentially adding the carrier resin, the low-molecular-weight polypropylene, the pigment, the dispersing agent and the coupling agent into a low-speed stirrer for mixing; adding a processing aid, an anti-ultraviolet stabilizer and a fluorine-containing polymer, and mixing; plasticizing, extruding and cooling the mixture by using a screw extruder; and hardening the obtained product, granulating by using a granulator, passing through a fine vibrating screen, and completely cooling and drying the color master batch to obtain the finished product. The color master batch has the beneficial effects that the pigment can be well dispersed in the carrier resin uniformly, and the prepared color master batch has good biodegradability and good anti-ultraviolet performance and is more environment-friendly to use.

Description

technical field [0001] The invention relates to the field of color masterbatch manufacturing, in particular to an anti-ultraviolet environment-friendly color masterbatch and a preparation method thereof. Background technique [0002] The color masterbatch is a plastic colorant that is well dispersed by a high proportion of pigments or additives and thermoplastic resins. Capacitance. Color masterbatch is generally composed of three parts, colorant, carrier and dispersant. After being kneaded by a high-speed mixer, crushed, extruded and pulled into granules. During plastic processing, color masterbatch has high concentration and good dispersibility. , cleaning and other significant advantages. Masterbatches are widely used in plastic processing industries such as injection molding, extrusion molding and blow molding. [0003] With the improvement of environmental protection requirements, higher requirements are also put forward for the degradation of color masterbatches. T...
