Abstract

The invention relates to a preparation method of a modified color master batch, and belongs to the technical field of color master batches and modified materials. The method comprises the following steps: proportioning of raw materials, grinding, mixing and heating, cooling, and extrusive granulation. Compared with the prior art, the modified color master batch disclosed by the invention has the beneficial effects that the modified color master batch is prepared from a plurality of raw materials in a reasonable ratio, so that the product has excellent dispersion uniformity, smoothness, flexibility and low-temperature resistance, and obviously improves the product quality; meanwhile, the fluorescent agent is added into the modified color master batch, so that the modified color master batch has a fluorescent function.

Description

technical field [0001] The invention relates to the technical field of color master batches and modified materials, in particular to a preparation method of modified color master batches. Background technique [0002] The full name of Color Master Batch is called color masterbatch, also called color seed, it is a new type of special colorant for polymer materials, also known as pigment preparation (Pigment Preparation). Color masterbatches are mainly used in plastics. The color masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate prepared by uniformly loading super-normal pigments in the resin. It can be called pigment concentration (Pigment Concentration), so its Tinting power is higher than the pigment itself. When processing, a small amount of color masterbatch and uncolored resin is mixed to achieve the colored resin or product with the designed pigment concentration. [0003] During the preparation process of the e...
