Abstract

The invention relates to the field of plastic master batches, and discloses an antioxidant metal-like plastic master batch and a preparation method thereof. The preparation method comprises the following steps: (1) performing ultrasonic cleaning on a metallic pigment powder by using a cleaning agent solution to obtain the cleaned metallic pigment powder; (2) adding titanium fluozirconate, gamma-aminopropyltriethoxysilane, a buffer agent, a coalescing agent and an antirust agent into water to obtain a coating solution; (3) spraying the coating solution on the surface of the cleaned metallic pigment powder, standing, washing with water, filtering and drying to obtain an antioxidant metallic pigment; and (4) mixing, extruding and granulating a carrier resin, a dispersing agent, a coupling agent and the antioxidant metallic pigment to obtain the antioxidant metal-like plastic master batch. According to the invention, the surface of the metal pigment powder is cleaned and then coated with acomposite ceramic membrane, so that the prepared metal-like plastic master batch has excellent oxidation resistance and corrosion resistance, and can keep good metallic luster and texture of metal-like plastic in long-term storage and use.

Description

technical field [0001] The invention relates to the field of plastic masterbatch, and discloses an anti-oxidation metal-imitating plastic masterbatch and a preparation method thereof. Background technique [0002] Plastic is an important organic synthetic polymer material. With the development of industrial technology and social life, plastic has attracted attention because of its plasticity, recyclability and adjustable strength. Plastic combines the hardness of metal, the lightness of wood, the transparency of glass, the corrosion resistance of ceramics, and the elasticity and toughness of rubber. Therefore, in addition to daily necessities, plastics are more widely used in aerospace, medical equipment, petroleum Chemical, machinery manufacturing, national defense, construction and other industries. [0003] As people's decorative and functional plastics are getting higher and higher, many functional plastics continue to appear. In the product design and production proce...
