Embodiment 1

[0019] Under normal temperature and pressure, prepare 100kg micro-foaming universal white masterbatch, the weight of each component is: polyethylene-ethylene-butylene-styrene copolymer 13kg, ethylene-vinyl acetate copolymer 3.5kg, rutile titanium dioxide 74kg, 7.5kg of polyethylene wax, 1.2kg of zinc stearate, 0.5kg of ethylene bisstearamide, 10100.3kg of phenolic antioxidants, after proportioning each component, pre-mix each component in a mixer at a low speed (conventional premixing process in this industry) for 5 minutes, then high-speed mixing (conventional mixing process in this industry) for 15 minutes, and finally melt and blend the fully mixed materials in a twin-screw extruder, the temperature is controlled at 200 ° C, the screw speed The pigment is uniformly dispersed in the carrier resin by shearing and kneading of the screw at 200r / min, and then granulation, drying, packaging and other processes are carried out to obtain the color masterbatch of the present inventio...

Embodiment 2

[0021] Under normal temperature and pressure, prepare 100kg of foaming high-dispersion, impact-resistant, high-concentration general-purpose white masterbatch. The weight of each component is: polyethylene-ethylene-butylene-styrene copolymer 14kg, ethylene-vinyl acetate copolymer 3.5kg , titanium type titanium dioxide 48kg, polyethylene wax 7.5kg, zinc stearate 1.2kg, ethylene bis stearamide 0.5kg, phenolic antioxidant 10100.3kg, calcium carbonate 25kg, after proportioning each component, first Pre-mix the components in the mixer for 5 minutes at low speed, then mix at high speed for 20 minutes, and finally melt and blend the fully mixed materials with a twin-screw extruder. The temperature is controlled at 210°C, and the screw speed is 200r / min. The shearing and kneading of the pigment make the pigment evenly dispersed in the carrier resin, and then carry out granulation, drying, packaging and other processes to obtain the color masterbatch of the present invention.

Abstract

The invention discloses a universal white master batch and a preparation method thereof. The color master batch of the invention is characterized by high dispersion, impact resistance, high concentration and strong universality in different materials and consists the following components by weight percentage: 15 percent to 20 percent of carrier resin, 40 percent to 80 percent of pigment, 5 percent to 10 percent of dispersant, 0 percent to 5 percent of processing aid, 0 percent to 2 percent of heat stabilizer and 0 percent to 40 percent of filler. All the components are mixed according to proportion, premixed at low speed for 0 minute to 10 minutes in a mixer, then mixed at high speed for 5 minutes to 25 minutes; melt blending is carried out by adopting a screw extruder, with the temperature controlled between 190 DEG C to 220 DEG C and the screw rotational speed of 80r/min to 400r/min; by the shearing and mixing of the screw, the pigment is dispersed evenly in the carrier resin and the color master batch of the invention is obtained after granulation, drying and packaging. The preparation method of the color master batch of the invention is simple and economical and has a wide application prospect.

Description

technical field [0001] The invention relates to the field of plastic coloring, in particular to a general-purpose white masterbatch and a preparation method thereof. Background technique [0002] There are three methods of plastic coloring: toner coloring, dyeing coloring, and masterbatch coloring. Direct toner coloring is very simple, but there are disadvantages such as color point, color difference, and production environment pollution. The coloring effect of dyeing and granulation is better than that of toner, but the cost is high and the performance of the material will decrease after heat treatment. The pigment is pre-dispersed and evenly dispersed in the carrier resin, which greatly improves the dispersibility and coloring efficiency of the pigment, and has low cost and no pollution to the environment. [0003] However, plastic coloring has many colors due to varieties, and different materials have different requirements for color masterbatches. This leads to a wide...
