[0002] The full name of masterbatch is masterbatch, also called color seed. It is a new type of special colorant for polymer materials, also known as pigment preparation. Masterbatch is mainly used in plastics. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading an extraordinary amount of pigment in the resin. The ink method is a commonly used method for making masterbatch. It is a production method that uses ink paste in masterbatch production, that is, through three-roll grinding, a low-molecular protective layer is coated on the surface of the pigment, and the ground fine paste is mixed with the carrier resin, and then plasticized by a two-roll plasticator (also called a double-roll open mill), and finally granulated by a single-screw or twin-screw extruder. The two-roll plasticator is composed of rollers, a pitch adjustment device, a steam passing device and a roller temperature adjustment device. It is widely used because of its simple structure, easy operation and convenient cleaning.
