Problems solved by technology

However, silver ions age under conditions such as light, which leads to darkening of the product color and decline in antibacterial performance, which in turn limits the weather resistance and long-term effect of antibacterial to a certain extent.
In addition, the current antibacterial fan is mainly added in the form of coating, and there are the following problems: 1. Due to the relatively single color restriction of the coating agent, it is impossible to make personalized choices; 2. Special equipment and tooling support are required, resulting in relatively high costs. ;3. The antibacterial coating only stays on the surface of the fan material, and the antibacterial effect is poor in the area not covered by the coating, and the antibacterial durability is limited

Abstract

The invention discloses a double-ion composite antibacterial material, an application and a preparation method thereof. The double-ion composite antibacterial material comprises the following components in parts by weight: 60-90 parts of a plastic base material; 0.1-3 parts of a silver-zinc composite antibacterial agent; 0.4-0.8 part of an organic antibacterial agent; 1-6 parts of a dispersant; 10-35 parts of an inorganic filler; and 0.1-1 part of an antioxidant. According to the invention, the double-ion composite antibacterial material has good mechanical properties and ideal antibacterial and mildew-proof properties, can be directly used for preparing fan blades of cross-flow fans of air conditioner internal units, further eliminates the use defects of existing antibacterial coatings, remarkably improves the production efficiency of the fan blades, reduces the production cost and improves the antibacterial durability.

Description

technical field [0001] The invention belongs to the field of materials, in particular, the invention relates to a dual-ion composite antibacterial material and its application and preparation method. Background technique [0002] For products such as air conditioners and fans, consumers pay more attention to the cleanliness and health of indoor air during the use of air conditioners. At the same time, with the improvement of living standards, young people have gradually become the main force of air-conditioning consumption, and they have put forward higher requirements for air quality and air health during the use of air-conditioning. [0003] The cross-flow fan of the internal unit is used as the air supply source of the indoor air conditioner. At present, it is mainly made of AS material and glass fiber reinforcement. During long-term use, it is easy to generate dust accumulation, and then bacteria and mildew will appear on the fan blades, resulting in air conditioner fail...
