Abstract

The invention discloses an antibacterial plastic master batch, which in parts by weight includes, plastic raw materials: 120 to 200 parts, a nano-zirconium phosphate-loaded silver antibacterial agent:50 to 80 parts, a surface treatment agent: 0.8 to 1.5 parts, and an auxiliary agent: 1.0 to 3.0 parts. The antibacterial plastic master batch of the present invention is a non-toxic grade substance and has a high degree of security. The nano-zirconium phosphate-loaded silver antibacterial agent treated by the surface treatment agent is uniformly distributed in the plastic, has no agglomeration phenomenon, and has good compatibility with the plastic. Antibacterial plastic prepared by the present invention has an antibacterial rate of 99% or more against Pseudomonas aeruginosa, Staphylococcus aureus, and E. coli, has a very small decrease in antibacterial performance after soaking in hot water, and has highly efficient, broad-spectrum, and long-lasting antibacterial properties. At the sametime, the antibacterial plastic master batch has excellent photoaging performance.

Description

technical field [0001] The invention belongs to the technical field of plastic production, in particular to an antibacterial plastic masterbatch and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards and the growing development of the plastic industry, consumers have higher and higher requirements for the performance of plastic products. In response to market demand, the plastic product processing industry is also more willing to use various types of functional masterbatches that are easy to operate to achieve the purpose of reducing raw material costs, process costs, improving process production efficiency, and enhancing the different properties of plastic products. Plastic functional masterbatch is a molding plastic processing aid developed in the 1980s. It is prepared by adding plastic additives that exceed the conventional amount to the carrier resin. Therefore, when molding plastic products, the plast...
