Example Embodiment

[0034] Example 1 High-toughness antibacterial plastic and its preparation

[0035] The formula of high-toughness antibacterial plastic: 40 parts by weight of polyphenylene ether, 80 parts by weight of polystyrene, 1 part by weight of oleic acid and n-propylamine modified silver nanoparticles, methacrylate-butadiene-styrene core-shell structure copolymer 物20 parts by weight.

[0036] The preparation process of high toughness antibacterial plastic includes the following steps:

[0037] (1) Dry the raw materials at 75°C for 10 hours;

[0038] (2) Weigh the dried raw materials according to the formula, stir and mix in a high-speed mixer at 70°C at 400 rpm for 10 minutes, and then extrude and granulate in a twin-screw extruder. The temperatures from the feeding section to the die are: 25°C, 230°C, 240°C, 240°C, 240°C, 250°C, 250°C, 250°C, 240°C, and the rotating speed is 180 revolutions per minute. The mixture is heated and melted. The body, driven by the screw, flows out from the die, is...

Description

technical field [0001] The invention relates to a plastic, in particular to a high-toughness antibacterial plastic and a preparation process thereof. Background technique [0002] Plastics are widely used in the industrial field and people's daily life. With the continuous development of high-performance polymer materials, their application fields are also expanding, and they have penetrated into various sectors of the national economy. As household daily necessities and increasingly popular household appliances enter thousands of households, many shared items such as telephones, elevator buttons, computer keyboards, refrigerator inner brackets, kitchen utensils, and various electrical switches and other touching parts will become sources of pollution and bacteria. source of transmission, thereby affecting the health of users. The best way to solve this problem is to endow the material itself with the ability of antibacterial and sterilizing. [0003] Currently commonly us...
