Problems solved by technology

When the color masterbatch and plastic particles are mixed, the color masterbatch with a larger specific gravity sinks slowly, which causes a large change in the content of the color masterbatch in the plastic product, so the color of the pro

Embodiment 1

[0027] Take 10kg of polyethylene, 60kg of titanium dioxide, 1kg of aluminate coupling agent, 10kg of low molecular weight polyethylene wax, and 19kg of calcite powder. The special flat hole die of the machine head is formed into a flat strip, which is cooled by a water tank, and then pelletized by a pelletizer, supplemented by adjusting the traction speed of the pelletizer to adjust the side length and thickness of the color masterbatch to make a side length 2mm×3mm, 0.5mm thick flake color masterbatch.

Embodiment 2

[0031] Take 90kg of polypropylene, 0.5kg of phthalocyanine blue, 0.1kg of titanate coupling agent, 5kg of ethylene bisstearamide, and 4.4kg of talcum powder. It is formed into a flat strip by the special flat hole die of the extruder head, cooled by a water tank, and then pelletized by a pelletizer, supplemented by adjusting the traction speed of the pelletizer to adjust the side length and thickness of the color masterbatch , to make a flake color masterbatch with a side length of 10mm×5mm and a thickness of 1mm.

Embodiment 3

[0035] Take 40kg of polystyrene, 20kg of modified polystyrene, 25kg of mica titanium pearl powder, 1kg of transparent red EG, 14kg of low molecular weight ethylene-vinyl acetate copolymer wax, 0kg of coupling agent, and 0kg of filler. The twin-screw extruder is melted, kneaded and extruded. It is formed into a flat strip through the special flat hole die of the extruder head. It is cooled by a water tank, and then pelletized by a pelletizer, supplemented by adjusting the traction of the pelletizer. Adjust the side length and thickness of the color masterbatch according to the speed, and make a flake color masterbatch with a side length of 8mm×6mm and a thickness of 1.5mm.

Abstract

The invention relates to the field of plastic coloring, in particular to a lamelliferous color master batch for plastic coloring and a manufacturing method of the lamelliferous color master batch. The manufacturing method of the lamelliferous color master batch includes the steps that the lamelliferous color master batch is a cuboid or cube, the side length ranges from 1 mm to 10 mm, the width ranges from 1 mm to 10 mm, and the thickness ranges from 0.2 mm to 1.5 mm; the lamelliferous color master batch comprises components of, by weight percentage, 10%-90% of carriers, 0.01%-70% of a coloring agent, 0%-5% of a coupling agent, 0%-30% of a dispersing agent and 0%-70% of padding; and through a double-screw extruder, the components are molded into a flat material strip through a flat orifice die of an extruder head, cooling and granulating are conducted, and the lamelliferous color master batch is obtained finally. By means of the lamelliferous color master batch, the condensation of the color master batch in a plastic product is kept stable, and the stability of the color of the plastic product is guaranteed.

Description

technical field [0001] The invention relates to the field of plastic coloring, in particular to a flake-shaped color masterbatch for plastic coloring and a preparation method thereof. Background technique [0002] Plastic coloring methods are divided into granulation method, toner method and masterbatch method, among which the masterbatch method is the most applicable and the most widely used. [0003] The common shapes of masterbatches are ellipsoid and cylinder. The diameter of the ellipsoid is usually 2mm-4mm, and the thickness is 1mm-3mm; the length of the cylinder is 2mm-4mm, and the diameter is 1.5mm-3mm. Regardless of whether it is an ellipsoid or a cylindrical masterbatch, the surface area or volume of the particles is basically the same as the surface area or volume of the plastic particles. Because the masterbatch contains high concentration of pigments, the specific gravity of the masterbatch is generally very large, up to 1.5g / cm 3 ~2.5g / cm 3 . The specific g...
