Abstract

The invention relates to the field of plastic master batches, and discloses a low-cost metal-like plastic master batch and a preparation method thereof. The preparation method comprises the followingsteps: (1) mixing large-particle metal powder, an inorganic filler powder, water, a surfactant and an adhesive, and carrying out ball-milling treatment to prepare a primary coating filler; (2) carrying out ultrasonic dispersion on the preliminary coating filler and separating out a part with a relatively good coating effect to obtain a metal pigment with a core-shell structure; and (3) carrying out mixed melting on a carrier resin, a dispersing agent, a coupling agent and the metal pigment with the core-shell structure, and carrying out screw extrusion granulation to obtain the low-cost metal-like plastic master batch. Compared with a common metal-like plastic master batch, the metal-like plastic master batch has the advantages that the inorganic pigment is coated with the large-particle metal powder to obtain the metal pigment with the core-shell structure, the cost of the obtained metal-like plastic master batch is reduced, the metal luster and the texture are good, and the metal pigment is uniform in color distribution, free of chromatic aberration and chromatic dispersion in a plastic product.

Description

technical field [0001] The invention relates to the field of plastic master batches, and discloses a low-cost imitation metal plastic master batch and a preparation method thereof. Background technique [0002] With the development of industrial technology, plastics are more and more widely used in various industries and scientific research fields due to their plasticity, recyclability and adjustable strength, and more and more attention is paid to the surface decoration and protection of plastics. Moreover, the different properties of plastics determine their use in life and industry. With the advancement of technology, research on plastic modification has never stopped. Plastics can be used more widely after modification, and gradually become an irreplaceable important material. [0003] In the product design and production process of automobiles, home appliances, toys and other industries, plastic parts are often required to have a metallic texture. The traditional solut...
