AI Technical Summary

Problems solved by technology

However, the existing technology is usually a physical compatibility method, and the coating layer is easy to fall off and fail during processing, which is very limited in improving the compatibility between plastic resins and metal pigments, so it cannot solve the surface quality problem caused by the agglomeration of metal pigments

Abstract

The invention relates to an aesthetic resin composition having a metal appearance and a preparation method thereof. The aesthetic resin composition comprises: by weight, 100 parts of one or more matrix resins, 0.2 to 5.0 parts of one or more amphiphilic polymers, 0.1 to 4.0 parts of one or more metal pigments, 0.1 to 4.0 parts of pearlescent pigments, 0.1 to 2.0 parts of one or more lubricants and 0.1 to 1.0 part of anti-oxidants. The preparation method comprises the following steps of stirring the raw materials in a high-speed mixer for mixing, feeding the mixture into a double screw extruder, carrying out conveying, shearing and mixing by screws so that the raw materials are melted and compounded, and carrying out extrusion, bar-drawing, cooling and granule-cutting to obtain the aesthetic resin composition having a metal appearance. Compared with the prior art, the aesthetic resin composition solves the problems of surface pitting and color spots caused by adverse dispersion and infiltration of metal pigments in matrix resins, and can be directly molded by injection molding, extrusion and blow molding.

Description

Technical field [0001] The invention relates to a resin composition and a preparation method thereof, in particular to an aesthetic resin composition with a metallic appearance and a preparation method thereof. Background technique [0002] In recent years, consumer products have generated a strong demand for plastics with unique colors and appearances. For example, the current appearance products with flickering effect and metallic texture are more and more favored by consumers. Compared with the traditional single tone, this unique appearance can bring great visual impact to people and enable consumers to enjoy For its aesthetic design, we call this material aesthetic resin. [0003] The traditional technical solution of Aesthetic Resin is to post-process the molded product. The spraying process is the most used, and pearl paint, metallic paint, etc. can be selected according to product needs. However, the spraying process has many limitations, such as complex procedures and hi...
