Problems solved by technology

[0004] In other documents or patents, most of them only use pearlescent or silver powder (aluminum pigment) to prepare the spray-free effect, but they do not take into account the combination of the two and the influence of the particle size change of aluminum pigment on the shimmering effect

[0040] According to the composition formula (parts by weight) in Table 1, ABS resin, high rubber powder, PC resin, PMMA resin, compatibilizer, antioxidant, light stabilizer, lubricant and toner were mixed and added from the main feeding port. To the twin-screw extruder, mix the white pearlescent and aluminum pigments and add it to the twin-screw extruder from the side feed port (screw diameter is 35mm, length-diameter ratio L / D=40, and the side feed port is located at the fifth heating port. segment) in the screw barrel. The control temperature of each section of the screw barrel (from the feeding port to the head outlet) is 120°C, 230°C, 230°C, 230°C, 230°C, 230°C, 230°C, 230°C, 230°C, 245°C, and the speed of the twin-screw At 450 rpm, the extruded strips are cooled in a water tank and then cut into pellets to obtain the product.

Abstract

The invention relates to the field of general-purpose resin, and provides a high-gloss high-flickering-effect ABS composite material and a preparation method thereof. The color master batch comprises the following components in parts by weight: 30-90 parts of ABS (Acrylonitrile Butadiene Styrene) resin, 10-30 parts of high glue powder, 0-50 parts of PC (Polycarbonate) resin, 0-20 parts of PMMA (Polymethyl Methacrylate) resin, 2-10 parts of compatilizer, 1-1.5 parts of functional additive, 0.05-0.2 part of toner, 0.3-3 parts of white pearlescent and 0.3-3 parts of aluminum pigment, according to the invention, pearly luster is matched with the aluminum pigment, so that a traditional spraying-free product has a better flickering effect, and the grain size of the aluminum powder is further controlled to achieve the better flickering effect.

Description

technical field [0001] The invention relates to the field of general resins, and provides an ABS composite material with high gloss and high flickering effect and a preparation method thereof, which can be widely used in the fields of automobiles, household appliances and the like. Background technique [0002] ABS resin is a terpolymer of acrylonitrile (A), butadiene (B) and styrene (S) developed in the 1940s on the basis of the modification of polystyrene resin. Since ABS is copolymerized by three monomers, it can show the synergistic properties of the three components. ABS is granulated or powdered with a density of 1.02~1.08g / cm 3 , non-toxic, odorless, it has excellent mechanical properties, good impact toughness, 3 to 5 times higher than PS, although the impact performance is sensitive to notch, but the notch sensitivity is less than many other plastics, ABS The stiffness, hardness and fatigue strength are all good. Combining the above advantages, ABS has a wide ran...
