Abstract

The invention belongs to the technical field of spraying-free materials, and particularly relates to a spraying-free metal effect material and a preparation method thereof. A spraying-free metal effect material is prepared from the following raw materials: an acrylate copolymer, an acrylate polymer, a polystyrene series high-molecular polymer, metal powder and an antioxidant. The spraying-free metal effect material prepared by the invention can solve the problem about the overall stability of the system and the dispersing performance and wettability of metal powder, pearl powder and the like in the system, can better imitate the appearance of the coating effect of metals such as aluminum, bronze, red copper, gold or bronze, is low-carbon and environment-friendly, avoids the problems of three wastes and huge energy consumption, and has lower cost and high economic benefit.

Description

Technical field[0001]The present invention belongs to the technical field of sprayable material, and more particularly to a sprayable metal effect material and a preparation method thereof.Background technique[0002]No metal-free metal effect material is a natural injection molding, no need to spray environmentally friendly materials, because it can directly affect special pearlescent, fully recycled, no pollution, reduce environmental burden, no follow-up processing, reduce unit product costs become current comparison Popular functional materials.[0003]However, because of the use of aluminum silver powder in the traditional free metal effect material, the dust is large, the working environment is poor, and it is difficult to disperse in the preparation system, resulting in the selection of raw materials from spraying metal effect materials into a problem. In order to further enhance the pigment, the dispersability and infiltration of silver powder in the plastic system, while contro...
