Modified polymer plastic color masterbatch and preparation method thereof

Abstract

The invention discloses modified polymer plastic color masterbatch and a preparation method of the modified polymer plastic color masterbatch. The modified polymer plastic color masterbatch comprises,by weight, 60-80 parts of carrier resin, 15-20 parts of coloring agent, 3-5 parts of compatilizer, 10-15 parts of brominated polystyrene, 6-8 parts of ultraviolet absorber UV-P, 8-12 parts of light stabilizer, 3-5 parts of dispersing agent, 5-8 parts of environment-friendly plasticizer, 6-8 parts of antibacterial agent, 5-10 parts of wear-resisting agent and 100 parts of water. Polypropylene obtained after plasma treatment is adopted as the color masterbatch carrier, so that the surface adhesive force of the polypropylene can be effectively improved; and the compatilizer is added in the preparation process, the compatilizer system can improve the affinity between the color master and other materials and improve the interfacial compatibility between the color master and the materials, so that the product quality is improved, the coloring agent is more evenly mixed with the color masterbatch carrier under the action of the dispersing agent, and the coloring effect of the color masterbatch carrier is improved.

Description

technical field [0001] The invention belongs to the technical field of color masterbatches, in particular to a preparation method of polymer modified plastic color masterbatches. Background technique [0002] The color masterbatch is composed of a high proportion of pigments or additives and thermoplastic resins. It is a well-dispersed plastic colorant. The selected resin has a good wetting and dispersing effect on the colorant, and has a good compatibility with the material to be colored. Capacitance, therefore, masterbatch has a wide range of uses. [0003] Due to the good physical and chemical properties of thermoplastic elastomers, modified plastics and color masterbatches, as well as better environmental protection performance and recyclability than traditional materials, they are widely used in the automotive industry, household appliances, medical and health, and rail transportation , Construction engineering and other industries have a wide range of applications, an...

Problems solved by technology

[0005] 1. In the processing process of the existing masterbatch preparation equipment, the color masterbatch after granulation is usually collected and stored directly through a masterbatch storage device, because the cutter will produce more debris during the granulation process Mixed in the masterbatch, resulting in more debris in the masterbatch in the masterbatch storage device, resulting in poor quality of the finished product of the masterbatch. In the subsequent use of the masterbatch, it needs to be screened separately, and the waste is relatively large. A lot of manpower and material resources;

[0006] 2. The existing color masterbatch has poor antibacterial and wear-resistant effect, which limits the scope of use of the color masterbatch. At the same time, the color masterbatch is prone to damage during use, which shortens the service life of the color masterbatch;

[0007] 3. The existing color masterbatch directly mixes the pigment and filler with the carrier resin during the preparation process, and the mixed color material cannot completely achieve a uniform effect, resulting in uneven coloring of the color masterbatch during coloring;

[0008] 4. In the granulation process of the current color masterbatch preparation equipment, the extrusion screw is usually directly driven by the motor to rotate, resulting in loud noise during the extrusion process of the color masterbatch
