Abstract

The invention provides a transparent plastic master batch containing a self-assembled composite transparent powder, and a preparation method thereof. The preparation method comprises the following steps: successively adding nano-mica powder, nano-talcum powder, nanometer barium sulfate, emulsified wax, silicic acid and a calcium salt into water, assembling the added materials into the spherical transparent composite powder, mixing the spherical transparent composite powder with polyethylene wax to prepare a modified spherical transparent composite powder, mixing the modified spherical transparent composite powder with white oil, a coupling agent, a dispersant, a lubricant, a brightening agent and a polymer, and carrying out screw extrusion, filtration and granulation to obtain the transparent plastic master batch. The nano-mica powder, the nano-talcum powder and the nanometer barium sulfate are assembled into the spherical transparent composite powder by the method, so the advantages of the three are integrated, and the obtained composite transparent powder has excellent transparency in the polymer, and dispersion is benefited, thereby the obtained transparent master batch granulehas the characteristics of good gloss and brightness, uniform size, light white, slight transparence, smoothness, fineness and good application prospect.

Description

technical field [0001] The invention relates to the technical field of plastic masterbatch, in particular to a plastic transparent masterbatch containing self-assembled composite transparent powder and a preparation method thereof. Background technique [0002] The application of filler masterbatch in plastics was originally to reduce the raw material cost of plastic products and save synthetic resin. Because the masterbatch is not only a filling material, but also has the characteristics of improving the physical properties of plastic products and improving processing efficiency, the development speed is very fast. However, because most of the filler masterbatch market is low-end, manufacturers blindly reduce costs without technical support, ignoring performance and high-end requirements. At present, as the price of plastic raw materials continues to rise, some high-end plastic products have also begun to add filler masterbatches in order to reduce costs. This puts forwar...
