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...
