Embodiment 1

[0018] An anti-ultraviolet black masterbatch, the mass percentage of each component is:

[0019] Carbon black 30%;

[0020] Acrylonitrile-styrene copolymer 45%;

[0021] Calcium stearate 8%;

[0022] Polyethylene wax 8%;

[0023] UV-3853S anti-ultraviolet stabilizer 9%.

[0024] A method for preparing an anti-ultraviolet black masterbatch, comprising the following steps: weighing each component according to the above-mentioned weight ratio, adding them to a high-speed mixer respectively, stirring at a speed of 1500r / min for 20 minutes, and releasing the mixture after being uniformly mixed. Feed into the twin-screw extruder, at 260 o After melting and kneading at C temperature, extrude and granulate, cool, dry and package to obtain the required black masterbatch.

Embodiment 2

Abstract

The invention relates to an anti-ultraviolet black masterbatch, the mass percentage of each component is: carbon black 30%-50%; carrier resin 25%-45%; dispersant 0.5%-8%; high temperature stabilizer 3%- 8%; anti-ultraviolet stabilizer 0.5%-13%, also relates to the preparation method of this color masterbatch, comprises the following steps: take each component by weight ratio, and add in the high-speed mixer respectively, at 1500-1800r/ Stir for 10-20 minutes at a speed of 1 min, and after mixing evenly, discharge the material into a twin-screw extruder, melt and knead at a temperature of 180°C to 260°C, extrude and granulate, cool, dry, and pack to obtain The required black masterbatch, the black masterbatch has anti-ultraviolet function and can meet the needs of use.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an anti-ultraviolet black masterbatch and a preparation method thereof. Background technique [0002] Black masterbatch is a kind of masterbatch, but its status is somewhat different from other masterbatches. Black masterbatch is the most commonly used color masterbatch in plastic processing, and it is also the largest amount of color masterbatch. Black masterbatch is a plastic colorant that is well dispersed with a high proportion of pigments or additives and thermoplastic resins. The selected resin has good wetting and dispersing effects on the colorant, and has good compatibility with the material to be colored Properties, that is: pigment + carrier + additive = masterbatch. Black masterbatches are widely used in plastic processing industries, such as injection molding, extrusion molding and blow molding. In real life, it is widely used in the injection molding of...
