Abstract

The invention discloses an oil-resistant antibacterial HIPS alloy material and a preparation method thereof. The oil-resistant antibacterial HIPS alloy material is prepared from the following components in percentage by mass: 77-87% of HIPS resin, 5-15% of PE resin, 3% of a composite compatibilizer, 2% of an antibacterial agent and 3% of other auxiliaries, wherein the composite compatibilizer is formed by compounding an ethylene acrylic acid copolymer elastomer, maleic anhydride and an ethylene copolymer elastomer. A step-by-step material mixing mode is adopted, process parameters are adjusted, and low-density polyethylene is introduced from a molecular structure; and due to the addition of the composite compatibilizer, the HIPS and the PE resin have good compatibility, the molding of the material is ensured, the strength is obviously improved, and the oil resistance is enhanced.

Description

technical field [0001] The invention relates to the technical field of modified polymer materials, in particular to an oil-resistant and antibacterial HIPS alloy material and a preparation method thereof. Background technique [0002] HIPS is High Impact Polystyrene, which has the advantages of easy processing, excellent dimensional stability, high impact strength and high rigidity. However, there are certain limitations in heat resistance, oxygen permeability, UV stability and oil resistance. Chemistry and Properties Impact polystyrene is made by dissolving polybutadiene rubber in styrene monomer prior to polymerization. Although suspension polymerization can be used to prepare HIPS, the current industrial production of HIPS is mainly bulk polymerization. In the bulk polymerization process, the mixture of styrene monomer, rubber and additives passes through a series of reactors, and the conversion rate reaches 70-90%. Widely used in refrigerator special liner, door linin...
