Modified antibiotic sweat-resistant plastic for keyboards and mice, and preparation method thereof

Abstract

The invention relates to a modified antibiotic sweat-resistant plastic for keyboards and mice, and a preparation method thereof. The method comprises the following steps: mixing matrix resin with a high performance composite antiseptic, adding a certain amount of an antioxidant, a flexibilizer, a coupling agent and other assistant to cooperate with highlight master batch, extruding through a double screw extruder, carrying out low temperature die heat hot cutting granulation, and drying to prepare the plastic. The matrix resin is PP, ABS, HIPS, PET or PC. The preparation method has the following advantages: an inorganic and organic combination composite antibiotic technology is adopted, so the singleness of an inorganic antiseptic is solved, and easy elution, poor heat resistance and other disadvantages of an organic antiseptic are solved; the antiseptic is directly combined with a raw material to realizes one shot molding during manufacturing without adhesion to an antibiotic coat, so the process flow is simplified, the cost is reduced, and the shedding problem of the coat is solved; and a fluorine-containing acrylic copolymer is added in the processing process, so the above material has the advantages of certain hydrophobic and oleophobic characteristics, easy surface cleaning, effective avoiding of oil and dust accumulation, and prevention of breeding of bacteria.

Description

technical field [0001] The invention relates to the field of polymer material modification, in particular to a modified antibacterial, waterproof and sweat-resistant plastic for a keyboard and mouse and a preparation method thereof. Background technique [0002] Since human society stepped into the information age, computers have become an indispensable darling around us. No matter from various aspects such as office, life and entertainment, we have to deal with computers everywhere. And the way we deal with it is nothing more than the following two most common, keyboard and mouse. [0003] The keyboard and mouse are the peripheral products that humans use the computer most frequently, and at the same time, they must be the products that have been in contact for the longest time. In our daily use, we will inevitably use the keyboard and mouse when our hands are stained with oil or water. At the same time, our palms and fingers will also secrete sweat and excrement. These so...

This process method not only increases the difficulty of the process and operation, but also increases the possibility of damage to the appearance of the product caused by the peeling off of the coating. At the same time, some seams and pores may not be covered by the coating, so that antibacterial and waterproof effects cannot be achieved. Affect the overall effect of the product
