Abstract

The invention discloses an antibacterial and flame-retardant plastic, which consists of the following components in parts by weight: 100-105 parts by mass of PS, 20-25 parts by mass of natural rubber, 10-20 parts by mass of soybean oil, 10-15 parts by mass of hexamethylene propylene glycol ester, 10-15 parts by mass of triethylenetetramine, 10-14 parts by mass of zirconia, 10-13 parts by mass of dipropylene glycol, 10-20 parts by mass of isoprene rubber and 10-14 parts by mass of corn flour. The plastic prepared by the invention has good antibacterial and flame-retardant functions; it does not affect the mechanical strength of the plastic; at the same time, it has good compatibility with the resin and does not migrate, separate out or be extracted in plastic products.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an antibacterial and flame-retardant plastic. technical background [0002] With the development and progress of society and the improvement of material living standards, people have higher and higher requirements for living and working environments, especially hygienic environments. Because plastic has the advantages of light weight, no rust, and good insulation, it is used in many aspects of home appliance production. But in daily life, quite a few harmful bacteria exist and multiply on the surface of plastic products, such as: telephones, washing machines, computers, refrigerators, electrical switches, etc., and cause various diseases through contact; People who come into contact with various bacteria, molds and other microorganisms will become the source of bacterial pollution and disease transmission. However, as people's awareness of health and environmental p...
