Embodiment 1

[0041] This embodiment provides a high-yield high-strength electroplated PC / ABS alloy product, including the following components in parts by weight:

[0042] PC 80 copies

[0043] ABS resin 15 parts

[0044] Polybutylacrylate 5 parts

[0045] Antioxidant 1010 0.4 parts

[0046] 0.5 parts of stearic acid amide;

[0047] The electroplated PC / ABS alloy product of the present embodiment is made by following method:

[0048] (1) Mixing: Weigh the raw materials according to the above parts by weight, add ABS resin, polybutylacrylate, antioxidant 1010, and stearic acid amide into a high-speed mixer and mix for 2 minutes to obtain a premix;

[0049] (2) Extrusion granulation: Add the premix into the barrel of the twin-screw extruder through the feeding device, set the pressure to -0.1MPa, the screw speed to 300r / min, and set the temperature of the barrel of the extruder to 5 The sections are 190°C-210°C-230°C-240°C-240°C in sequence. First, melt and plasticize evenly in the firs...

Embodiment 2-9

[0052] The only difference between Examples 2-9 and Example 1 is that the raw materials or proportions of electroplated PC / ABS alloy products are different. The raw material components and proportions of Examples 2-9 are shown in Table 1.

Abstract

The invention belongs to the technical field of polymer products, and particularly discloses a high-yield and high-strength electroplating PC / ABS alloy product and a preparation method thereof. ABS resin, polyacrylate and auxiliaries are added into an extruder through a charging barrel, polycarbonate resin is added into a side feeding port in the middle section of the extruder, melt is injected into an injection molding machine after sufficient mixing, and finally the PC / ABS alloy product is prepared. Compared with a common preparation method, the preparation method of the electroplating PC / ABS alloy product has the advantages that, a step-by-step feeding mode is adopted in the extrusion granulation process, a cell structure can be formed in the PC / ABS alloy product, the coarsening effectis improved, the binding force between the PC / ABS alloy product and a plating layer is enhanced, and therefore the electroplated PC / ABS alloy product with the high polycarbonate content has the high yield.

Description

technical field [0001] The invention belongs to the technical field of polymer products, and in particular relates to an electroplated PC / ABS alloy with high yield and high strength and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is an amorphous thermoplastic polymer material with high strength, high toughness, high heat resistance, high dimensional stability and chemical corrosion resistance. It is the second largest engineering plastic and is widely used in construction, Medical, home appliances, automobiles, aerospace and other fields. However, PC has disadvantages such as high viscosity, poor processability, easy stress cracking, sensitivity to notch, and easy wear. Acrylonitrile-butadiene-styrene copolymer (ABS) not only has good processing performance, impact resistance, low temperature resistance, chemical corrosion resistance, but also has good electroplating, welding, hot pressing, bonding, etc. performance. Therefore, the PC / AB...
