Abstract

The invention discloses an ABS/PBT alloy material and a preparation method thereof. The ABS/PBT alloy material comprises the following ingredients in parts by weight: 64 to 76 parts of ABS, 14 to 24 parts of PBT, 3 to 6 parts of flexibilizer, 2 to 5 parts of bulking agent, 0.5 to 1 part of lubricant, 1 to 2.5 parts of scratch-resistant agent, and 0.4 to 0.8 part of anti-oxidant. The tenacity of an ABS basis material is enhanced by adding the PBT; the defect that the dual structure of ABS/PBT is unstable is overcome by adding the bulking agent, so that two types of matrix resins can be compatible to each other better; the scratch resistance of the alloy material is improved by adding the scratch-resistant agent, so that excellent physical comprehensive performance is obtained. The preparation method mainly comprises two steps of mixing and melt extrusion, so that the process is simple, no additional complex equipment is required, the cost is low, the performance of the composite polymer material is improved, and suitability for industrial production is realized.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an ABS / PBT alloy material and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene (ABS) has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties, and also has the characteristics of easy processing, stable product size and good surface gloss. It can be widely used in industrial fields such as machinery, automobiles, electronic appliances, instrumentation, textiles and construction. It is one of the five general-purpose plastics; however, there are some shortcomings that limit the use of ABS in a wider range of fields, such as its relatively high hardness and high performance. Brittle, and its scratch resistance is also limited, so ABS cannot be used as a base material in some environments that require good toughness. [0003] Polybutylene terephthalate...
