Background
The black colored rubber is a coloring pigment widely used for rubber products, and the applied industries include rubber foaming, shoe undersoles, sealing parts, tires, rubber parts and the like. The raw material carbon black for producing black color glue is an important chemical material, is a black powdery substance formed by gas-phase combustion or pyrolysis of hydrocarbons under strictly controlled process conditions, and mainly contains elemental carbon and also contains a small amount of oxygen, hydrogen, sulfur and the like. The strength of black color paste depends on the particle size of carbon black, the toner concentration of the color paste, and the mixing and dispersing process. In the aspect of shoe factories, when the black colored rubber is used as a coloring agent to produce shoe soles, if the colored rubber is not subjected to good dispersion treatment, the produced rubber soles have the defects of uneven color concentration, dispersed points, poor glossiness and no black appearance, and the consequences of customer complaints and enterprise compensation are caused.
The demand of the current market for high-concentration color master batches is increased, and the higher the pigment content in the color master batches is, the more difficult the pigment is to disperse, so that the high-concentration color master batch product has high requirements on the pigment, the processing difficulty of the master batches is increased, and the requirement that the pigment is well dispersed is the basic performance requirement of the color master batches. The dispersant has the functions of wetting and coating the pigment and assisting the dispersion of the pigment in the production process of the color master batch; the carrier has the functions of enhancing the affinity between the pigment and a coloring body and improving the coloring effect, the good carrier can improve the dispersibility of the pigment in the color master batch, the using amount of the pigment is less, the coloring quality is kept, but the pigment is far from enough, the mechanical property of a coloring product can be improved, and the carrier depends on the following three factors in the process: the pigment is easy to disperse, and the pigment is high-efficiency processing equipment and a high-efficiency dispersing agent.
The traditional production process is a dry mixing method, and the technical route is that pigment, dispersant and carrier resin are extruded and granulated through a screw after being stirred at high speed. The method has simple process and easy operation, but the pigment dispersion degree in the master batch is relatively low, and most of the plastic master batches are produced by adopting a dry mixing process at present.
Therefore, the research on the processing and preparation process, the dispersion principle and the performance requirements of the high-concentration color master batch is urgent.
