Abstract

The invention provides an antibacterial polystyrene composite material and a preparation method and evaluation method thereof. The antibacterial polystyrene composite material comprises, by weight, 42-85 parts of polystyrene, 15-30 parts of a styrene-butadiene-styrene block copolymer, 2-10 parts of a styrene-maleic anhydride copolymer, 5-20 parts of an ethylene and hexane comonomer polymer, 0.5-2parts of a photocatalyst antibacterial agent and silver inorganic antibacterial agent compound, and 0.2-1 part of an antioxidant. The antibacterial polystyrene composite material and the preparation method and evaluation method thereof are provided to develop the antibacterial polystyrene composite material which can meet the multi-axial impact test standard.

Description

technical field [0001] The invention belongs to the field of modified plastics, and in particular relates to an antibacterial polystyrene composite material, a preparation method and an evaluation method thereof. Background technique [0002] Polystyrene is the third largest variety of general-purpose plastics. It has the advantages of transparency, good formability, good rigidity, easy dyeing, low hygroscopicity and low price. It is used in packaging, electronics, construction, automotive appliances, instruments, daily necessities and toys. and other industries have been widely used. But polystyrene is brittle and has low impact strength. Therefore, increasing its toughness has always been an important topic of PS modification. [0003] However, the disadvantage of the polystyrene composite materials disclosed in the prior art is that no satisfactory combination of impact toughness and good ductility is obtained, and the polystyrene compositions disclosed in the prior art...
