Problems solved by technology

The current methods used to improve the bonding force of PC / ABS electroplating, in addition to adding a large amount of ABS or high rubber powder to increase the rubber phase, and adding inorganic fillers to increase the etching point, these two methods will destroy the strength and other properties of the material, and In the electroplating process, there will be shortcomings such as low yield rate and defects on the surface after plating. Therefore, it is urgent to prepare an electroplating grade PC / ABS alloy material with high electroplating bonding force, less defects after plating, and excellent comprehensive performance.

Embodiment 1

[0048] It includes the following raw materials by weight: PC-1: 10 parts, ABS-1: 70 parts, carboxyl-terminated nitrile rubber 20 parts, antioxidant 0.3 part, lubricant 0.4 part. The material composition is added into a high-speed mixer for mixing, then added into a twin-screw extruder, extruded and granulated, and the temperature in the processing temperature zone is controlled at 200-240°C. After the granulation is completed, dry at 70-90°C for 3-4 hours to fully remove moisture, control the injection mold temperature at 60-90°C, barrel temperature at 220-250°C, injection speed at 30-70mm / s, and injection pressure at 30-70bar. An electroplating grade PC / ABS alloy injection molded product of 140×90×3 mm was obtained.

Embodiment 2

[0050] It includes the following raw materials by weight: PC-1: 30 parts, ABS-1: 45 parts, carboxyl-terminated nitrile rubber 25 parts, antioxidant 0.3 part, lubricant 0.4 part. The material composition is added into a high-speed mixer for mixing, then added into a twin-screw extruder, extruded and granulated, and the temperature in the processing temperature zone is controlled at 200-240°C. After the granulation is completed, dry at 70-90°C for 3-4 hours to fully remove moisture, control the injection mold temperature at 60-90°C, barrel temperature at 220-250°C, injection speed at 30-70mm / s, and injection pressure at 30-70bar. An electroplating grade PC / ABS alloy injection molded product of 140×90×3 mm was obtained.

Abstract

The invention provides an electroplating grade PC / ABS alloy material with high electroplating binding force and a preparation method thereof. The electroplating grade PC / ABS alloy material contains: 10-70 parts by weight of polycarbonate (PC), 10-70 parts by weight of styrene-butadiene-acrylonitrile copolymer (ABS), 20 parts by weight of terminalized nitrile rubber -35 parts by weight and optional additives, wherein the polycarbonate, styrene-butadiene-acrylonitrile copolymer and end-grouped nitrile rubber add up to 100 parts by weight. The invention further optimizes the injection molding process of the electroplating grade PC / ABS alloy product. The electroplating grade PC / ABS alloy material of the present invention has the advantages of easy electroplating, high electroplating bonding force, high yield rate and few surface defects when it is made into products.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to an electroplating grade PC / ABS alloy material and a preparation method thereof. The present invention further relates to an electroplating grade PC / ABS alloy product and a preparation method thereof. Background technique [0002] Polycarbonate PC has the advantages of high impact strength, high light transmittance, excellent mechanical properties, good heat resistance, flame retardancy, and good dimensional stability. It is widely used in automobiles, electronic appliances, construction and other industries, but it also has some Disadvantages, such as high melt viscosity and large residual internal stress, lead to stress cracking and notch sensitivity. On the other hand, ABS is mainly composed of graft copolymers (polybutadiene as the main chain, styrene and acrylonitrile as branched copolymers), copolymers of styrene and acrylonitrile, and ungrafted polybutadiene. , ...
