Imitation wood grain color master batch, preparation method, and applications thereof

Abstract

The invention discloses an imitation wood grain color master batch, which comprises the following components in percentage by weight: 60 to 95% of carrier resin, 1 to 20% of pigment, 1 to 15% of dispersant, and 0 to 5% of other auxiliary agents; wherein the carrier resin is a mixture of PC and ABS, the PC accounts for 0 to 80% of the total weight of the carrier resin, and the ABS accounts for 20 to 100% of the total weight of the carrier resin. The preparation method comprises the following steps: (a) adding the components according to the ratios mentioned above into a high-speed mixer, and evenly mixing the components at the normal temperature and under the normal pressure; (b) melting, mixing and extruding the mixed materials mentioned above in a double-screw extruder, and at the same time subjecting the extruded materials to processes of water cooling, cutting, and wind drying so as to obtain the imitation wood grain color master batch. The imitation wood grain color master batch has the advantages of little color powder usage amount, good temperature toleration ability, and excellent dispersing ability; is easy to operate and control when the color master batch is applied to prepare imitation wood grain composite material of wood and plastic; has a good compatibility with PVC base basic materials and a high imitation wood appearance, thus the formed grains are natural and clear, the surface color is bright and beautiful, and the imitation wood grain effect is good.

Description

Technical field [0001] The invention involves the field of coloring of imitation wood grain differential materials, which specifically involves an imitation wood grain female granules and their preparation methods and applications in imitation wooden plastic composite materials. Background technique [0002] As a new type of environmentally friendly material, wooden plastic composite materials have attracted widespread interest in their light, good touch, anti -corrosion, moisture -proof, insect -proof, flame retardant and other advantages.In order to make it better imitation wood and decorative, improve the quality of wood plastic composite materials, squeeze out the imitation wood composite material with wood grain shape to maximize the psychological needs of people's pursuit of natural wood, which has become the current.Hot spots for research at home and abroad.PVC base imitation wood grain composite wood has the characteristics of wood nailing, sawing, and planing. It can rep...
