Embodiment Construction

[0018] Prepare the preparation method of above-mentioned nano antibacterial non-woven fabric:

[0019] A. Preparation of non-woven filter material base material

[0020] First, weigh the polypropylene fiber and the silver-based nano-antibacterial powder according to the above-mentioned ratio of parts by weight, put the two into a high-speed stirrer and fully stir and mix them for ten minutes to make the base of the antibacterial non-woven filter material. material;

[0021] B. Mixed melting

[0022] Put the base material of non-woven filter material into the extruder, the inner temperature is 140-180℃, 4-6kg / cm 3 Mixing and melting under working conditions, extruded to make a liquid mixture;

[0023] C. Meltblown

[0024] Fill into the melt-blown injection molding equipment in the ultraviolet disinfection workshop, at 140-180°C, 4-6kg / cm 3 Under the working conditions of the melt-blown injection molding machine, the liquid mixture is melt-blown and injected, and th...

Abstract

A nano-class antibacterial non-woven fabric as filter material is prepared from polypropylene fibre and antibacterial silver nanoparticles through proportionally mixing, smelting, and melt spraying. Its advantages are high filtering effect and durable strong power to kill bacteria.

Description

technical field [0001] The invention relates to a nano antibacterial non-woven fabric filter material and a preparation method thereof. Background technique [0002] The main component currently used to prepare antibacterial non-woven fabrics is ordinary polyester fiber or polypropylene fiber. The production process is generally to soak the ordinary fiber in the immersion tank containing the drug, squeeze and clean the excess drug solution adsorbed between the fibers, and then dry it in an oven or cylinder to obtain the drug fiber. The drug fiber and Auxiliary fibers are blended, loosened, carded, laid, and then processed into antibacterial non-woven fabrics by one of the methods of spunlace, gluing, hot rolling, and hot bonding. The antibacterial non-woven fabric produced by this method has poor antibacterial stability, durability and washability. At the same time, the texture is poor, the comfort is not enough, and the production cost is also high. The Chinese patent do...
