Anti-aging special color master batch formula

Abstract

The invention discloses an anti-aging special color master batch formula, and belongs to the field of color master batches. According to the anti-aging special color master batch formula, through thearrangement of light shielding balls, in the preparation process of a color master batch, on one hand, the light shielding balls can uniformly disperse internally stored light shielding powder into amixture, and the color master batch prepared by the method has high reflective rate, so that the accelerated influence of external sunlight on the aging speed of the color master batch is effectivelyreduced, the embrittlement and strength reduction time caused by long-time exposure to the sunlight is prolonged, the service life of plastic using the color master batch is remarkably prolonged, andthe fading of plastic products is effectively avoided; on the other hand, in the preparation process of high-speed stirring, the light shielding balls can effectively grind other ingredients, so thatthe fineness of the particle size of each ingredient is reduced, the coloring effect of the natural color master batch is remarkably improved, and plastic using the natural color master batch is colored more uniformly.

Description

technical field [0001] The invention relates to the field of color masterbatches, and more specifically relates to a formula for anti-aging special color masterbatches. 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] Color masterbatch has the following advantages: [0004] ...

AI Technical Summary

Problems solved by technology

[0007] Due to poor selection of color masterbatches, plastics are prone to aging after long-term use or in the sun, which not only leads to gradual fading of plastics, but also easily causes plastics to become brittle and brittle, resulting in a lower service life. There is also a problem with the granules. During the preparation process, the particle size distribution of each ingredient is relatively narrow, which leads to uneven coloring of the plastic during the preparation of the plastic, which makes the color difference in the plastic part, resulting in poor coloring effect.
