Abstract

A preparation method of antibacterial ABS resin comprises the steps: a, mixing and stirring a zeolite powder and nano titanium dioxide, stirring and mixing for 3-5 minutes at room temperature at the speed of 90-140 rpm, and drying; b, adding the zeolite powder and nano titanium dioxide mixed material of the step a and ABS into a stirrer, at the same time, adding nano silver oxide and polyhexamethylene guanidine phosphate to the stirrer, stirring and mixing for 20 minutes at room temperature at the speed of 60 rpm in the stirrer to obtain an ultimate mixture; and c, adding the ultimate mixture obtained after stirring in the step b into a twin-screw extruder with the processing temperature of the twin-screw extruder of 200 DEG C and the main engine speed of 320 rpm, drawing rods through extrusion, air-drying, and sized-dicing to obtain the antibacterial ABS resin. The antibacterial ABS resin has the beneficial effects that inorganic sterilization adopts combination of a titanium dioxide photocatalytic technology and silver ion sterilization, moreover, potent bactericidal polyhexamethylene guanidine phosphate is adopted, inorganic sterilization and organic sterilization are combined, and thus the sterilization effect is greatly improved.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial ABS resin. Background technique [0002] In our lives, some harmful bacteria exist and multiply on the surface of plastic resin products. The parts of household appliances that are in frequent contact with the human body and objects, such as refrigerator shelves, plastic cup lids, door handles, mice, keyboards, The surface of the mobile phone casing and so on is a place where bacteria multiply. [0003] The hands of the human body are in contact with plastic products and are contaminated with bacteria, which can lead to various diseases. As users' awareness of health continues to increase, there is a demand for "antibacterial and sterilizing" plastic parts of household appliances that are frequently touched in daily life. [0004] The development and research of antibacterial plastics began in the 1980s, and great progress has been made with the technology of Japan and Western develope...
