Antibacterial household appliance plastic and preparation method thereof

Abstract

The invention discloses an antibacterial household appliance plastic and a preparation method thereof. The plastic is prepared from the following raw materials in parts by weight: 22-28 parts of ABS resin, 10-15 parts of bentonite, 2-15 parts of acrylate resin, 5-18 parts of methylated amino resin and 11-20 parts of an antibacterial agent, wherein the antibacterial agent is prepared from the following raw materials in parts by weight: 2-4 parts of lithium aluminate, 5-8 parts of nano-strontium oxide, 2-6 parts of silicon boride, 4-7 parts of 2-methoxyl-4-methylphenol, 2-5 parts of jasmine lactone, 0.1-1 part of trichloroethyl phosphate and 30-45 parts of a hydrochloric acid solution having a mass percentage of 3-6 percent. The antibacterial household appliance plastic has a relatively good antibacterial effect on gram-positive staphylococcus aureus, gram-negative escherichia coli and saccharomycetes, has the antibacterial rate of more than 90 percent, and does not destroy other performance of the plastic. The preparation process is simple, and has excellent application value and economic value.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a plastic for antibacterial household appliances and a preparation method thereof. Background technique [0002] Household appliances are indispensable in our daily life. Microorganisms on home appliances are pathogens in the form of bacteria and molds, which can easily infect humans, animals and plants, cause diseases, and endanger human health and life. The use of antibacterial materials in home appliances is an effective means to solve the above problems. Studies have shown that organic antibacterial materials have weak antibacterial properties, and their decomposition products and volatiles may be harmful to the human body, so their applications are limited. Inorganic antibacterial materials have the advantages of high safety, good heat resistance and durability. Inorganic antibacterial materials are mainly oxide-loaded silver, molecular sieve-loaded silver, etc. The silve...

Problems solved by technology

However, silver changes color after interacting with some substances and loses its antibacterial effect, and the effect gradually decreases with the dissolution of silver ions, which has become a factor restricting its wide application.

Another type of titanium oxide antibacterial agent has two problems: first, only the anatase titanium oxide has photocatalysis under ultraviolet irradiation, that is, it exhibits antibacterial and bactericidal effects, and because the cell wall is sensitive to photocatalysis , some bacteria have a protective effect on this reaction; second, there must be oxygen to show antibacterial effect
