Environment-friendly antibacterial ABS plastic and preparation method thereof

Abstract

The invention belongs to the technical field of plastic, and particularly relates to environment-friendly antibacterial ABS plastic and a preparation method thereof.The environment-friendly antibacterial ABS plastic comprises an ABS plastic layer, the upper surface of the ABS plastic layer is covered with a second protective layer, and the upper surface of the second protective layer is covered with a first protective layer; the ABS plastic layer is prepared from the following components in parts by weight: 75-80 parts of regenerated ABS particles, 30-45 parts of organic silicon rubber, 25-40 parts of polylactic acid, 15-25 parts of modified montmorillonite, 6-10 parts of a composite antibacterial agent, 3-8 parts of a heat-resistant agent, 3-6 parts of a dispersing agent, 2-4 parts of a silane coupling agent, 2-3 parts of an antioxidant and 1-3 parts of a plasticizer; by using hectorite / tetradecyl trimethyl ammonium bromide / chitosan as the composite antibacterial agent, the antibacterial effect is remarkable, the sterilization speed is high, the antibacterial spectrum is wide, the safety is high, the performance stability is good, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of plastics, and relates to an environment-friendly antibacterial ABS plastic and a preparation method thereof. Background technique [0002] With the development and progress of society and the increasing improvement of material living standards, people have higher and higher requirements for living and working environment, especially sanitary environment. Because plastic has the advantages of light weight, no rust, good insulation, etc., plastic is used in many aspects of home appliance production. However, in daily life, a considerable part of 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; therefore, in life, people inevitably To come into contact with all kinds of bacteria, mold and other microorganisms, will become the source of bacterial conta...

AI Technical Summary

Problems solved by technology

[0003] In addition, inorganic antibacterial agents have good heat resistance, wide antibacterial spectrum, high safety, and long antibacterial validity period, but they are highly toxic to human body, easy to change color, difficult to disperse evenly in plastic products, relatively large dosage, high cost and cause environmental pollution

These antibacterial agents are often easy to leak out during long-term use due to their compatibility with the plastic substrate and their own dispersion, thus affecting the stability of plastic performance and service life.
