Long-acting broad-spectrum antibacterial polyethylene material and preparation method thereof

Abstract

The invention discloses a long-acting broad-spectrum antibacterial polyethylene material and a preparation method thereof. The long-acting broad-spectrum antibacterial polyethylene material is prepared from the following components: 88.4 to 98.3 percent of polyethylene, 0.3 to 3 percent of nano titanium dioxide, 0.5 to 5 percent of nipagin ester, 0.2 to 1 percent of dispersing agent, 0.5 to 2 percent of coupling agent and 0.2 to 0.6 percent of antioxidant. The invention has the following beneficial effects: the low processing temperature is adopted to protect the nano titanium dioxide, the dispersing agent is adopted to ensure the dispersity of the nano titanium dioxide, the performance of the polyethylene product is ensured on the basis of lower addition amount of the nano titanium dioxide, and the organic antibacterial agent and the inorganic antibacterial agent are combined, the prepared antibacterial polyethylene product has good antibacterial long-term effect and stability.

Description

technical field [0001] The invention relates to a modified polyethylene composite material, in particular to a polyethylene material with broad-spectrum antibacterial and long-lasting antibacterial functions, which is suitable for a rotational molding production process, and a preparation method thereof. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, people pay more and more attention to environmental hygiene and self-health, and antibacterial plastics have emerged as the times require. [0003] Antibacterial plastic refers to the addition of antibacterial agents to plastics to make the plastic itself antibacterial, which can kill or inhibit the bacteria on the plastic within a certain period of time. Compared with conventional chemical and physical methods, the use of antibacterial plastics has a long sterilization time. It is economical and convenient. Antibacterial plastics can inh...
