Problems solved by technology

Among them, the production of color masterbatches with medium and low concentration monochrome pearlescent masterbatches as raw materials has certain defects in the design of the formula, and it is easy to cause a large proportion of secondary processing degradation of plastics, but blindly increasing the concentration of organic pigments will not only lead to higher costs , and it is easy to cause low dispersion of organic pigments in the masterbatch, resulting in poor coloring strength of the masterbatch

preparation example Construction

[0063] In addition, the present application correspondingly proposes a method for preparing the above-mentioned single-color organic masterbatch, which may include the following steps: mixing each raw material under heating conditions and then granulating.

[0064] Compared with the processing method in the prior art that only mixes the mixture of organic pigment and polyolefin resin in a mixer and then extrudes, this method can improve the dispersibility of the organic pigment and produce a high-concentration single-color masterbatch.

[0065] For reference, the mixing temperature in this application can be 50-100°C, such as 50°C, 55°C, 60°C, 65°C, 70°C, 75°C, 80°C, 85°C, 90°C, 95°C or 100°C etc. Specifically, a certain temperature within the above-mentioned temperature range can be maintained during the entire mixing process, or the temperature can be fluctuated in a small range within the above-mentioned range during the entire mixing process. The mixing time can be 10-30 m...

Embodiment 1

[0082] This embodiment provides an organic single-color masterbatch. The raw materials of the single-color organic masterbatch include 70wt% of organic pigment, 27wt% of polyolefin resin and 3wt% of dispersant in weight percentage.

[0083] Among them, the organic pigment is pigment red 48:2, the polymer material is PE, and the dispersant is hyperdispersant.

[0084] The single-color organic masterbatch is prepared through the following steps:

[0085] Mix the above-mentioned organic pigments, PE and dispersant according to the proportion in a continuous mixing mode at 75° C. for 20 minutes. Then it is cooled, crushed and transported to a twin-screw extruder with seven zones equipped with a vacuum degassing device for extrusion molding. The temperature of zone 1 to zone 7 is 100°C, 125°C, 165°C, 165°C, 165°C, 165°C and 155°C respectively, and the die head temperature is 145°C. The screw speed during extrusion was 800 rpm.

[0086] After granulation, the machine head is used...

Embodiment 2

[0089] This embodiment provides an organic single-color masterbatch. The raw materials of the single-color organic masterbatch include 70wt% organic pigment, 25wt% polyolefin resin and 5wt% dispersant by weight percentage.

[0090] Among them, the organic pigment is 70% of pigment red 48:2, the polymer material is PE and ethylene copolymer, and the dispersant is hyperdispersant.

[0091] The single-color organic masterbatch is made the same as in Example 1 through the following steps.

[0092] The coloring strength of the obtained single-color organic masterbatch is 104%.

Abstract

The invention provides a monochromatic organic master batch, a preparation method and an application thereof, and a color master batch, and belongs to the technical field of pigments. The monochromatic organic master batch is prepared from the following raw materials in percentage by weight: 41 to 80 percent of organic pigment, 15 to 59 percent of polymer material and not more than 10 percent of dispersing agent. The monochromatic organic master batch is prepared by mixing the raw material components under a heating condition and then extruding. Wherein at least part of the polyolefin resin isin a molten state in the mixing process. The monochromatic organic master batch has good dispersibility and tinting strength. The preparation method comprises the following steps: mixing the raw material components under a heating condition, and carrying out extrusion molding. The method is simple, easy to operate, short in time, high in efficiency and low in influence on color masterbatch cost.The monochromatic organic master batch can be used for preparing color master batch, the production process is dust-free, environment-friendly and clean, the production line is easy to clean, and theprocessing efficiency and color difference control rate of the color master batch can be effectively improved. The color master batch containing the monochromatic organic master batch is flexible in formula design and relatively low in cost.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a single-color organic masterbatch, a preparation method and application thereof, and a color masterbatch. Background technique [0002] The full name of Color Master Batch is color masterbatch, also called color species, which is a special colorant for polymer materials. The color masterbatch is composed of three basic elements: several kinds of pigments or dyes, carrier and additives, and the particles are made by uniformly loading super-normal pigments in the resin. Because its tinting strength is better than the pigment itself, no dust pollution, low addition ratio, and easy to blend with colored resins, it is currently widely used to replace powdered pigments in thermoplastic coloring. [0003] Organic pigments are insoluble organic substances, which are usually added to the substrate in a highly dispersed state to color the substrate. The fundamental difference between i...
