Abstract

The invention discloses a high-fluidity and high-strength PC / ABS alloy material and a preparation method thereof. The high-fluidity and high-strength PC / ABS alloy material comprises the following components in parts by weight: 65-70 parts of PC, 9-10 parts of ABS, 0.2-0.4 part of an antioxidant, 20-22 parts of a flame retardant, 0.1-0.2 part of a stabilizer and 5-5.5 parts of a lubricant. The preparation method comprises the following steps: weighing the components in parts by weight; the preparation method comprises the following steps: firstly, premixing PC polycarbonate and ABS for later use; the preparation method comprises the following steps: premixing a phosphite antioxidant, an organic tin stabilizer and lubricating wax for later use; and mixing the two premixes, adding the flame retardant, uniformly mixing, carrying out mixed chain extrusion, cooling, and homogenizing to obtain the PC / ABS alloy material. The invention relates to the technical field of high polymer materials, and particularly provides a high-flowability and high-strength PC / ABS alloy material and a preparation method thereof, which are compatible with high strength and high flowability and expand the application range of the material.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-fluidity and high-strength PC / ABS alloy material and a preparation method thereof. Background technique [0002] PC / ABS alloy is a composite material blended by polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS), which combines the excellent characteristics of the two materials, including the molding of ABS It also has the mechanical properties, high impact strength and high heat distortion temperature of PC, and the color is free of transparent particles. It is widely used in TV sets, computer casings and other fields. [0003] The PC / ABS alloy materials produced by the prior art have contradictions between impact strength and flow properties. When the flowability is improved, the impact strength is often reduced, and the material properties are neglected, which limits the application field of the product.
