Problems solved by technology

Such applications require resins with both ultra-high whiteness and strong sparkle to replace the pearlescent paint solution. However, ultra-high whiteness requires the addition of a large amount of white toner. The addition of these toners, especially high-hardness titanium dioxide If the addition of white toner is added, the pearlescent powder with a relatively large length and diameter will be worn away, so that the three-dimensional flashing effect of the pearlescent pigment will be greatly lost. If the amount of white toner is reduced in order to maintain the flashing effect, the whiteness of the product will not reach the final level. requirements for use

Abstract

The invention relates to an aesthetic resin for improving whiteness and scintillation effect and a preparation method thereof. The resin comprises the following components in parts by weight: 100 parts of base resin, 0.1-5 parts of white pigment, 0.1-2.0 parts of pearlescent pigment, 0.1-3.0 parts of lubricant, 0.2-1.0 part of antioxidant and 0.001-0.15 part of fluorescent whitening agent. The preparation method of the resin comprises the following steps: stirring and mixing the components in a high-speed mixer, and then transferring into a double screw extruder; under the transferring, shearing and mixing effects of double screws, melting and compounding the materials; and then extruding, performing bar drawing, cooling, and pelleting to obtain the product. The invention overcomes the disadvantage that the existing white aesthetic resin can not simultaneously realize high whiteness and high scintillation effect, and ensures that the apparent effect of the white aesthetic resin is greatly enhanced, thereby ensuring that the white aesthetic resin meets the higher appearance application requirements in the fields of household appliances, automobiles, consumable electronics and the like and greatly widening the application range of the white aesthetic resin product.

Description

technical field [0001] The invention relates to a resin and a preparation method thereof, in particular to an aesthetic resin for improving whiteness and sparkle effect and a preparation method thereof. Background technique [0002] Spray painting is favored by the public because it can bring outstanding appearance to the product, but the disadvantages of spray painting should not be underestimated: cumbersome process, low yield, high cost, and environmental pollution. In order to overcome these shortcomings, the spray-free aesthetic resin that replaces spray paint has attracted more and more attention from many entrepreneurs and the public, and has gradually become a new appearance solution. It can not only achieve the colorful hues produced by spray paint, pearlescent, and flashing effects , metal color and other special effects, and can also achieve effects that spray paint cannot achieve, such as semi-transparent, full-transparent and astigmatism. Common plastics that c...
