[0033] The preparation method of above-mentioned any PS composite material, comprises the following steps:

[0034] (1) Weigh 80-100 parts of PS, 20-30 parts of acrylate rubber, 10-16 parts of mica powder, 10-14 parts of vermiculite, 0.1-0.5 parts of antioxidant and 0.1- 0.3 parts of EBS were mixed and stirred evenly to obtain a mixture;

[0035] (2) extruding and granulating the mixture obtained in the step (1) from an extruder to obtain a PS composite material.

[0036] Step (2) is specifically:

[0037] Put the mixture obtained in step (1) into the hopper of the twin-screw extruder for extrusion and granulation, wherein the twin-screw extruder includes six temperature zones arranged in sequence, and the temperature of the first zone is 180-200°C , the temperature of the second zone is 210-230°C, the temperature of the third zone is 210-230°C, the temperature of the fourth zone is 210-230°C, the temperature of the fifth zone is 210-230°C, the temperature of the sixth zone ...

Embodiment 1

[0039] (1) Weigh 80 parts of PS, 20 parts of acrylate rubber, 10 parts of mica powder, 10 parts of vermiculite, 0.1 part of Irganox168, 0.1 part of EBS and mix them evenly to obtain a mixture;

[0040] (2) Extruding and granulating the mixture obtained in the step (1) to obtain PS composite material P1.

[0041] Among them, the temperature and screw speed of each zone of the twin-screw extruder are respectively: the temperature of the first zone is 180°C, the temperature of the second zone is 210°C, the temperature of the third zone is 210°C, the temperature of the fourth zone is 210°C, the temperature of the fifth zone is 210°C, and the temperature of the sixth zone is 210°C. The head temperature is 210°C, and the screw speed is 200r / min.

Embodiment 2

[0043] (1) Weigh 100 parts of PS, 30 parts of acrylate rubber, 16 parts of mica powder, 14 parts of vermiculite, 0.1 part of Irganox168, 0.2 part of Irganox1010, 0.2 part of Irganox1330, 0.3 part of EBS, mix and stir evenly to obtain a mixture;

[0044] (2) Extruding and granulating the mixture obtained in step (1) to obtain PS composite material P2.

[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 200°C, the temperature of the second zone is 230°C, the temperature of the third zone is 230°C, the temperature of the fourth zone is 230°C, the temperature of the fifth zone is 230°C, and the temperature of the sixth zone is 230°C. The head temperature is 230°C, and the screw speed is 280r / min.

Abstract

The invention relates to a PS composite material and a preparation method thereof. The PS composite material is prepared from the following components in parts by weight: 80-100 parts of PS, 20-30 parts of acrylate rubber, 10-16 parts of mica powder, 10-14 parts of vermiculite, 0.1-0.5 part of antioxidant and 0.1-0.3 part of lubricant. According to the PS composite material provided by the invention, the acrylate rubber has smaller particle size and larger specific surface area; the interface bonding strength between a PS resin matrix and the filling particles is high; the increase of the specific surface area of the particles leads to the rise of the ratio of the interface area; by adding constraint of the rearrangement motion such as chain segment on some motion units to the PS resin matrix, the vibration of a sound wave in the PS material needs to overcome greater resistance, and the silencing property is improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a PS composite material and a preparation method thereof. Background technique [0002] Polystyrene (PS) is an engineering plastic with excellent comprehensive properties. It has good dimensional stability, good insulation, oil resistance, and good molding performance. Although the overall performance of PS is excellent, in some special application fields, there are high requirements for noise reduction performance, and ordinary PS cannot meet this requirement, which greatly limits the application range of PS composite materials. [0003] In view of this reason, the present invention innovatively produces a PS composite material with excellent sound-absorbing performance to make up for the deficiency of the existing PS composite material. This PS material has not been reported so far, which is very important for expanding the application of PS composite materials. sign...
