Embodiment 1--5

[0034] (Adding white oil) Add PC resin, ABS resin, and various additives to the high-speed mixer and stir for 2 minutes at high speed, then add to the main feeder of the extruder, and then add to the twin-screw extruder for basic granulation. The temperature distribution of the extruder is as follows: from the feed section to the head: 240°C, 260°C, 260°C, 260°C, 255°C, 250°C, 250°C, 250°C, 250°C, die head: 260°C , After the material is extruded, it is water-cooled, pelletized, and then packaged. The pellets were dried in a blast oven at 120°C for 4 hours, and then test specimens were prepared by an injection molding machine.

Abstract

The invention provides a PC / ABS alloy material with high welding strength. The PC / ABS alloy material is prepared from, by weight, 30-65 parts of polycarbonate, 15-40 parts of styrene-butadiene-acrylonitrile copolymer, 10-20 parts of styrene-acrylonitrile copolymer, 3-5 parts of high rubber powder, 1-5 parts of compatilizer and 0.5-1 part of processing auxiliaries. The invention provides a preparing method for the PC / ABS alloy material with high welding strength. The invention further provides application of the PC / ABS alloy material with high welding strength to automotive upholstery (like an instrument board), domestic appliance and other components. The alloy material obtained through the method is excellent in physical property and high in welding strength, and can be used in automotive upholstery, domestic appliance and other components.

Description

technical field [0001] The invention belongs to the field of material science and relates to an alloy material, in particular to a PC / ABS alloy material with high welding strength. Background technique [0002] The alloy material of polycarbonate and acrylonitrile-butadiene-styrene copolymer is a thermoplastic plastic made of polycarbonate (Polycarbonate) and polyacrylonitrile (ABS) alloy, combining the excellent characteristics of the two materials . It has excellent formability, high impact strength and high temperature resistance, anti-ultraviolet (UV) and other properties. Due to its structural particularity, it has become the fastest growing general-purpose engineering plastic. [0003] The connection methods of plastic products include: plastic parts pressing, matching assembly, mechanical fastening, welding, etc. Welding is divided into: hot plate welding, hot air welding, hot rod and pulse welding, ultrasonic welding, infrared welding, laser welding. Plastic weld...
