Problems solved by technology

Dusty particles refer to particles suspended in the air with a particle size of less than 100 μm. These tiny particles can be suspended in the air, have strong fluidity with the air, and are small in size. It is difficult to effectively prevent them and seriously affect people's health.
At present, the screens of the existing screens are mostly polyester-coated chemical fiber nets, and the aperture size of the square holes is usually about 1×1mm 2 , which can prevent mosquitoes and insects from flying into the room. Block tiny particles in the air, low blocking rate and easy to age, not rainproof and waterproof, and lack of antibacterial properties
In this context, the existing screens are obviously not suitable for the needs of the times

Abstract

The invention relates to a konjac glucomannan air purifying nano screen window and a preparation method thereof. The preparation method of the konjac glucomannan air purifying nano screen window comprises the following steps of preparing a film stock solution, preparing a non-woven fabric, making a spinning solution, and preparing a nano window screen by using an electrospinning machine. The konjac glucomannan air purifying nano screen window provided by the invention adopts konjac glucomannan as a main material, and has higher tensile strength and higher antibacterial effect than a polyethylene material, and can keep the indoors clean and hygienic for a long time; nano cobalt ferrite is added to enhance the adsorption effect of the screen window to particles, enhance the weather resistance and toughness, improve the weathering resistance and prolong the service life; the non-woven fabric and a filter membrane layer are both made of natural ingredients, so that the screen window can becompletely biodegraded after being discarded, and is environmentally friendly and low carbon. The konjac glucomannan air purifying nano screen window provided by the invention has the advantages of small and uniform pore size, large tensile strength, good toughness, good gas permeability, anti-aging, convenience in material obtaining, low price and long service life.

Description

technical field [0001] The invention relates to a screen window and a preparation method thereof, in particular to a konjac glucomannan air-purifying nano screen window and a preparation method thereof. Background technique [0002] In recent years, air pollution has become more and more serious, affecting people's daily life. Dust particles are an important category of air pollution, which can enter the human respiratory system and are currently the biggest cause of lung disease. Dust particles refer to particles suspended in the air with a particle size of less than 100 μm. These tiny particles can be suspended in the air, have strong fluidity with the air, and are small in size. It is difficult to effectively prevent them and seriously affect people's health. At present, the screens of the existing screens are mostly polyester-coated chemical fiber nets, and the aperture size of the square holes is usually about 1×1mm 2 , which can prevent mosquitoes and insects from fly...
