Problems solved by technology

Although natural antibacterial agents have low toxicity and high safety, they have short service life and poor heat resistance
Organic antibacterial agents have the characteristics of quick effect and strong bactericidal ability, but they are prone to microbial resistance, and have defects such as easy migration and poor drug resistance, and many organic antibacterial agents are easy to decompose under conditions such as high temperature and high pressure, and the decomposition products will be later. lead to secondary pollution
Inorganic antibacterial agents have the advantages of good heat resistance and no drug resistance. Among the existing inorganic antibacterial agents, silver ion antibacterial agents have the best effect, but silver ions are easy to be reduced and change color. After reduction, the antibacterial effect is significantly reduced, and the price is relatively low. More expensive, and easy to accumulate in the human body and cause harm to the human body

Abstract

The invention discloses inorganic nano-composite antibacterial rubber-latex glove liquid concentrate and a preparation method thereof. The inorganic nano-composite antibacterial rubber-latex glove liquid concentrate comprises deionized water, an inorganic nano-composite antibacterial agent, a water-based dispersing agent, a water-based surfactant and a thickener. The prepared antibacterial liquid concentrate is on a nanoscale, and is high in antibacterial effect, easy to disperse and free of agglomeration. The prepared inorganic nano-composite antibacterial rubber-latex glove liquid concentrate can be directly added to a stock solution for preparing a rubber-latex glove, and the antibacterial glove with the high antibacterial effect can be prepared through a conventional rubber-latex glove production process.

Description

technical field [0001] The invention relates to a novel liquid masterbatch and a preparation method thereof, belonging to the field of polymer materials. Specifically, it relates to an inorganic nano-composite antibacterial liquid masterbatch for rubber latex gloves, which has a simple production process and has a broad-spectrum antibacterial effect. Background technique [0002] Commonly used rubber latex gloves, because they contain a large amount of bacterial nutrients, are likely to cause the growth of microorganisms or bacteria, which increases the risk of infection and disease. Therefore, it is necessary to add a certain amount of antibacterial ingredients to rubber latex gloves. Antimicrobial effect on glove surface. [0003] Antibacterial agents mainly include organic antibacterial agents, inorganic antibacterial agents and natural antibacterial agents. Although natural antibacterial agents have low toxicity and high safety, they have short service life and poor he...
