Embodiment 1
[0024] Example 1 Prepare 100 kg of polyethylene tire packaging film coloring masterbatch.
[0025] 1. The weight percent of each component is:
[0026] Titanium dioxide 56.0%
[0027] N-N' Ethylene Bis Stearic Acid Amide 5.0%
[0028] Zinc Stearate 2.0%
[0029] Polyethylene wax 8.0%
[0030] Antistatic agent 0.40%
[0031] Low Density Polyethylene 20.70%
[0032] Linear Low Density Polyethylene 7.90%
[0033] 2. Preparation method:
[0034] First, pre-mix the materials weighed in proportion, then put the mixture in a kneading pot with a current control of 35A and mix it at a high speed until it is coated, and then put the evenly stirred mixture into the twin-screw machine whose temperature is controlled at about 135°C. Extruded in an extruder, cooled, dried, and pelletized to make the required masterbatch.

Abstract
The coloring agglomerate consists of pigment, plastic assistants and carrier resin, and the plastic assistants include N, N'-ethylene amido bistearate, polyvinyl wax, zinc stearate and antistatic agent. The preparation process includes mixing the materials, high speed kneading in kneading pot with current controlled in 30-50 A, extruding the mixture in a double-screw extruder at 100-160 deg.c, cooling, stoving and pelletizing. The polyethylene tire-packing film with the coloring agglomerate has no color penetration, no adhesion, no falling off and antistatic performance, and may be used to complete the packing and storing of rubber tire at about 80 deg.c.
Description
Technical field [0001] The invention relates to the technical field of plastic coloring, in particular to a special coloring master batch for high-concentration polyethylene tire packaging film. [0002] The invention also relates to a preparation method of the colored masterbatch. Background technique [0003] The existing tire packaging film, because most of them use wax and zinc as plastic additives in the production process, and use the ordinary coloring masterbatch processed by traditional technology, so the performance of the product is not stable enough. Especially affected by its content, the concentration of the pigment is often not increased, so when the rubber tire is packaged at a temperature of about 80°C, the pigment is easy to migrate, bleed, and generate static electricity. When stored after cooling, it is very easy to absorb dust, and it is easy to stick to the tire, which is not conducive to peeling off, or it is difficult to roll if it slips. At the same...
