The black masterbatch of the black masterbatch manufacturer is a kind of masterbatch, but its status is somewhat different from that of other masterbatches. Black masterbatch is a kind of masterbatch commonly used in plastic processing, and it is also a kind of masterbatch with a large amount. Black masterbatch is a plastic colorant formed by a high proportion of pigments or additives and thermoplastic resin, which is well dispersed, and the selected resin has good wetting and dispersion effect on the colorant, and has good compatibility with the colored material, namely: pigment + carrier + additive = masterbatch.
Black Masterbatch Product Usage:
Black master manufacturers are widely used in the plastic processing industry, such as injection molding, extrusion molding, and blow molding. In real life, it is widely used in the injection molding of automotive plastic parts, the extrusion molding of plastic pipes, and the production of agricultural mulch films and geotextiles.
Black masterbatch production process:
(1) Ink method: As the name suggests, it is a production method that uses ink colorant in the production of masterbatch, that is, through three-roller grinding, a layer of low molecular protective layer is coated on the surface of the pigment. The ground fine color paste is then mixed with the carrier resin, and then plasticized by a two-roll plasticizer (also called a double-roll open mill), and then granulated by a single or twin screw extruder.
(2) Rinsing method: the pigment, water and dispersant are sanded to make the pigment particles less than 1μm, and the pigment is transferred to the oil phase through the phase transfer method, and then dried to obtain the masterbatch. Organic solvents are required for phase transfer, as well as corresponding solvent recovery devices.
(3) Kneading method: After mixing the pigment with the oily carrier, the pigment is used to make the pigment flush from the aqueous phase into the oil phase by using the lipophilic characteristics of the pigment. At the same time, the surface of the pigment is coated by an oily carrier to make the pigment disperse and stabilize and prevent the pigment from condensing.
