Problems solved by technology

Because this production process needs to mix the colorant, that is, the toner, into the carrier, the working environment is dusty and dusty during the production process; after the process of weighing the toner, due to the toner floating, it is easy to cause the proportion of the toner in production to vary. Inaccurate, the production of each batch of masterbatch will cause color deviation

Embodiment 1

[0022] Embodiment one, prepare red color masterbatch:

[0023] The purchased red toner is melted and extruded by a twin-screw extruder, then cooled by cooling water, and pelletized to make base color particles. The selected red toner is an inorganic toner; it is configured according to the ratio of the color masterbatch formula, and the color masterbatch includes a colorant, a carrier and a dispersant. In this embodiment, the colorant is a red primary color particle, the carrier is a PP chip, and the dispersant It is polyethylene low-molecular wax, the mass percentage of red base color particles is 40%, the mass percentage of carrier PP chips is 59.5%, and the mass percentage of dispersant is 0.5%. According to the quantity required by the customer, weigh each component according to the weight, and stir evenly to obtain the mixed material.

[0024] The materials obtained above are fed into the extruder, and after crushing, shearing and mixing, heating and melting, and extrusi...

Embodiment 2

[0025] Embodiment two, prepare blue masterbatch:

[0026] The difference with the embodiment is that the blue toner is made into blue primary color particles, the selected blue toner is inorganic toner, the carrier used is PET chips, and the dispersant is stearate. According to customer requirements, the function Sexual additive antimicrobial agent. The type of functional additives to be added depends on the requirements of the customer. The mass percentage of the blue base color particles is 30%, the mass percentage of the carrier PET chip is 69%, the mass percentage of the dispersant is 0.5%, and the mass percentage of the antibacterial agent is 0.5%. The preparation steps of the blue color masterbatch are consistent with the steps of the red color masterbatch in Example 1. The melt temperature required in the extruder is compatible with the physical properties of the PET chips and blue base color particles used.

Embodiment 3

[0027] Embodiment three, prepare blue masterbatch:

[0028] The difference from Example 2 is that no functional additives are added according to the requirements of the customer, and the selected blue toner is an inorganic toner; the carrier used is PA slices, and the dispersant is white oil. The mass percentage of the blue primary color particles is 40%, the mass percentage of the carrier PA chip is 59%, and the mass percentage of the dispersant is 1%. The melting temperature required in the extruder should be adapted to the physical properties of the PA chip and blue base color particles used.

Abstract

The invention discloses a production process of color masterbatch, which comprises: configuring according to the formula ratio of color masterbatch, color masterbatch including colorant, carrier and dispersant; feeding the material obtained by batching into an extruder, and passing through the crushing of the extruder , shear mixing, heating and melting, extrusion; the melt extruded by the extruder is cooled into solid material strips; the solid material strips obtained after cooling are pelletized to make color masterbatch; the colorant used is Base color particles processed from powdered toner. The color masterbatch production process involved in the present invention first processes the purchased powdery colorant into base color particles, so that there is no dust in the production process of the color masterbatch, which improves the working environment and safety, and is beneficial Workers are healthy. There is no scattering of powder during the weighing process, which improves the accuracy of weighing, makes the color stability better and the color deviation is smaller.

Description

technical field [0001] The invention relates to the technical field of color masterbatch production technology. Background technique [0002] The plastic coloring method is the most commonly used production process for masterbatch coloring. Color masterbatch is generally composed of three parts, namely colorant, carrier and dispersant. After kneading by high-speed kneading machine, it is crushed, extruded and diced. In the process of plastic processing, color masterbatch has significant advantages such as high concentration, good dispersibility, and cleanliness. [0003] The traditional coloring masterbatch production process is usually: through automatic metering, various raw and auxiliary materials are configured according to the product formula ratio; the configured materials are automatically fed into the extruder, and the materials are heated, sheared and mixed to melt and mix the mixture evenly. Make various additives uniformly dispersed in the polymer, and extrude t...
