Problems solved by technology

The low-viscosity PBT migrates to the surface of the PC / ABS alloy to form a dense grain structure, so as to achieve the effect of material oil resistance and high impact strength, but PBT is incompatible with PC / ABS, and the addition of too much PBT will reduce the alloy material. The mechanical properties, especially the notched impact strength

Abstract

The present invention provides an oil-resistant high-impact AS / PBT / PC alloy material and a preparation method thereof, wherein the composition of the oil-resistant high-impact AS / PBT / PC alloy material according to the weight ratio includes: 25-55 parts of AS resin , 31-50 parts of PBT resin, 5-15 parts of PC resin, 5-25 parts of toughening agent, 1-5 parts of compatibilizer, and 0.6-1 part of processing aid. The invention enhances the compatibility of AS and PBT materials by adding PC components, thereby improving the stability of materials in the production process, avoiding delamination of AS and PBT, and the prepared alloy materials have high impact strength and excellent oil resistance; Moreover, the prepared AS / PBT / PC has simple preparation process, excellent processability and low cost.

Description

technical field [0001] The invention relates to a polymer material, in particular to an oil-resistant high-impact AS / PBT / PC alloy material and a preparation method thereof. Background technique [0002] AS resin (acrylonitrile-styrene copolymer) and PBT resin have excellent oil resistance. However, both have disadvantages such as low notched impact strength, which limits its application. AS / PBT alloy effectively improves the oil resistance of AS and reduces the shrinkage rate of PBT material, but the alloy material still has low notched impact strength, and the alloy structure is unstable. AS is an amorphous polymer, while PBT It belongs to the blend of amorphous / crystalline polymers, which leads to phase separation of the two, resulting in unstable material properties. Therefore, the compatibility between AS and PBT should be increased to improve the mechanical properties of the alloy material. [0003] Chinese patent CN107312299A discloses a method of improving the oil ...
