Problems solved by technology

In such applications, not only ultra-high whiteness and strong flicker are required to replace the pearlescent paint scheme, but also a certain degree of coverage is required to prevent the front of the panel from seeing through the back ribs, indicator lights, structural parts, etc., and affecting the overall effect
However, increasing the covering degree, especially the addition of a large amount of titanium dioxide tends to sharply reduce the visible depth, greatly losing the three-dimensional shimmering effect of pearlescent pigments. In severe cases, pearlescent pigments even show defects similar to pitting, which deteriorates the original ultra-white color. Effect

Abstract

The invention relates to an aesthetic resin for improving white blink effect and a preparation method thereof. The aesthetic resin comprises 100 weight portions of resin matrix, 0.1-5.0 weight portions of white pigment, 0.1-2.0 weight portions of pearlescent pigment, 0-0.5 weight portions of cross-linked polymer, 0.1-3.0 weight portions of lubricant, 0.1-1.0 weight portions of anti-oxidant, and 0.001-0.15 weight portions of fluorescent brightener. The preparation method comprises the following steps: stirring and mixing the raw materials in a high speed mixer, then putting the mixed raw materials in a double screw extruder, under the conveying, shearing and mixing of the screws, melting and compounding the materials, then carrying out extrusion, pulling, cooling, and dicing on the materials to obtain the product. Compared with the prior art, the disadvantages of poor blink effect of present white aesthetic resin under the conditions of high whiteness and high-cover ratio are overcome, thus the apparent effect of the white aesthetic resin is greatly enhanced, the feasibility of a white blink free-spraying scheme is increased, and the market potential in the fields of automobile, household appliance, consumer electronics and the like is raised.

Description

technical field [0001] The invention relates to a resin and a preparation method thereof, in particular to an aesthetic resin for improving the white shimmering effect and a preparation method thereof. Background technique [0002] In response to the market trend of environmental protection and energy saving, aesthetic resins such as PP, ABS, PMMA, ABS / PMMA, PC, PC / ABS, ASA, polyester, PS, etc. without spraying have shown unprecedented market competitiveness. , flash effect, metallic color and other special effects are widely used in home appliances, automobiles, consumer electronics and other fields. [0003] However, during the injection molding process of aesthetic resins with special colors, there are often obvious defects such as flow marks and weld lines due to the flow orientation of metallic pigments or pearlescent pigments, which greatly limits the application range of special-effect aesthetic resins. Higher requirements. In view of this, General Electric Company ...
