preparation example Construction

[0038] A high-performance antibacterial PS composite material and a preparation method thereof, comprising the following steps:

[0039] (1) Weigh 80-100 parts of PS, 16-20 parts of composite filler, 4-6 parts of antibacterial agent, 0.1-0.5 part of antioxidant, 0.1-0.3 part of SEBS-g-MAH, mix and stir Uniformly, to obtain a mixture;

[0040] (2) Extruding and granulating the mixture obtained in step (1) to obtain a PS composite material.

[0041] Step (2) is specifically: use a twin-screw extruder to extrude and granulate, wherein the twin-screw extruder includes six temperature zones arranged in sequence, the temperature in the first zone is 150-170°C, and the temperature in the second zone is 200-240°C. ℃, the temperature of the third zone is 200~240℃, the temperature of the fourth zone is 200~240℃, the temperature of the fifth zone is 200~240℃, the temperature of the sixth zone is 200~240℃, the temperature of the head is 200~240℃, and the screw speed is 200~280r / min.

Embodiment 1

[0043] (1) Weigh 80 parts of PS, 16 parts of composite filler, 4 parts of Ionpure, 0.1 part of Irganox168, 0.1 part of SEBS-g-MAH, mix and stir evenly to obtain a mixture;

[0044] (2) Extruding and granulating the mixture obtained in the step (1) to obtain PS composite material P1.

[0045] Among them, the temperature and screw speed of each zone of the twin-screw extruder are respectively: the temperature of the first zone is 150°C, the temperature of the second zone is 200°C, the temperature of the third zone is 200°C, the temperature of the fourth zone is 200°C, the temperature of the fifth zone is 200°C, and the temperature of the sixth zone is 200°C. The head temperature is 200°C, and the screw speed is 200r / min.

Embodiment 2

[0047] (1) Weigh 100 parts of PS, 20 parts of composite filler, 6 parts of Zeomic, 0.1 part of Irganox168, 0.2 part of Irganox1010, 0.2 part of Irganox1330, 0.3 part of SEBS-g-MAH, mix and stir evenly to obtain a mixture;

[0048] (2) Extruding and granulating the mixture obtained in step (1) to obtain PS composite material P2.

[0049] Among them, the temperature and screw speed of each zone of the twin-screw extruder are respectively: the temperature of the first zone is 170°C, the temperature of the second zone is 240°C, the temperature of the third zone is 240°C, the temperature of the fourth zone is 240°C, the temperature of the fifth zone is 240°C, and the temperature of the sixth zone is 240°C. The head temperature is 240°C, and the screw speed is 280r / min.

Abstract

The invention relates to a high-performance antibacterial polystyrene (PS) composite and a preparation method thereof. The PS composite comprises the following components in parts by weight: 80-100 parts of PS, 16-20 parts of composite fillers, 4-6 parts of antibacterial agents, 0.1-0.5 part of antioxidants and 0.1-0.3 part of compatilizers, wherein the composite fillers are prepared by coating mica powder with nano TiO2; after the surface of the mica powder is coated with nano TiO2, the sharp edges are passivated; smooth crystal cleavage surfaces are roughened; the problem of local stress concentration in the prepared composite is relieved; meanwhile, through nano TiO2 coated on the surface of the mica powder, the interface action force between the fillers and the PS substrate is also enhanced, so that the mechanical performance of the PS composite is improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a high-performance antibacterial PS composite material and a preparation method thereof. Background technique [0002] Polystyrene (PS) has the advantages of light weight, non-toxic, odorless, good chemical stability, insoluble in common solvents at room temperature, and low water absorption. Although the comprehensive performance of PS is excellent, the antibacterial performance of PS is average, which greatly limits the application range of PS composite materials. Contents of the invention [0003] The purpose of the present invention is to provide a high-performance antibacterial PS composite material and its preparation method, so as to solve the problem of low antibacterial performance and mechanical performance of existing PS materials. [0004] The present invention is achieved through the following technical solutions: [0005] A high-performance antibacteri...
