Problems solved by technology

At present, the surface of extrusion-grade aesthetic resin is darker, the metal color texture is poor, and the effect of metal spray paint is far away, and the covering of aesthetic resin is poor, so the surface condition is easily affected by the color of PVC and ABS substrates
In addition, during the continuous extrusion process, the metal pigments will easily precipitate to the surface and accumulate in the mold, which will not only damage the surface of the aesthetic resin, but also affect the continuous production

Abstract

The invention relates to an extrusion grade aesthetical resin possessing metal color effect and its preparation method, which comprises the following ingredients by weight content: 100 parts of matrix resin, 0.1-3.0 parts of metal pigment, 0.1-3.0 parts of pearlescent pigment, 0.1-3.0 parts of molecular sieve adsorbent, 0.1-3.0 parts of lubricant and 0.1-1.0 parts of anti-oxidant. The method comprises the following steps: stirring and mixing the above raw materials in a high speed mixer, sending in a double screw extruder, under the conveying, shearing and mixing of a screw, fusing the raw materials, compositing, extruding, bracing, cooling, cutting into granule to obtain the extrusion grade aesthetical resin possessing the metal color effect. Compared with prior art, the extrusion surface effect of the extrusion grade aesthetical resin possessing metal color effect is close to metal spray paint effect, thereby the energy saving and environmental protection scheme without spraying can be realized, the aesthetical resin possessing metal color effect enables large market potential in the fields of automobile, household electrical appliance, consumer electronics and the like which possess high appearance requirement.

Description

technical field [0001] The invention relates to a resin and a preparation method thereof, in particular to an extrusion-grade aesthetic resin with a metallic color effect and a preparation method thereof. Background technique [0002] With the improvement of product appearance requirements, especially bright and colorful tones and special colors with pearlescent and flashing effects are becoming more and more popular. The traditional solution of spraying metallic paint and pearlescent paint on exterior parts has gradually shifted to spray-free technology due to the problems of environmental protection, high cost and low efficiency. Therefore, it is currently more popular to directly add metal pigments, mica titanium pearlescent pigments and other special color pigments to high-gloss plastic substrates instead of traditional spraying schemes, and the correspondingly prepared resins can usually be called aesthetic resins. Common plastics that can be used to prepare aesthetic ...
