Embodiment 1

[0043] Embodiment 1, supporting layer 1 selects silk diameter as 0.02mm, 80 object glass fiber silk screens, on supporting layer 1 upper end face spraying is the negative ion functional film layer 4 that the thickness of 50 μ m is 50 μ m with tourmaline powder as the main raw material adding polyurethane adhesive, This type of window screen is lighter and thinner and is used in environments with better air quality.

[0044] Replace the original window screen of the building with the window screen made in this embodiment and carry out the 1-hour window ventilation experiment. The data are as follows:

[0045] Before changing the window screen and opening the window for 1 hour to ventilate, the outdoor PM2.5 concentration is 120μg / m 3 , PM10 concentration is 308μg / m 3 , the negative ion concentration is 256 / cm 3 ; After opening the windows for 1 hour to ventilate, the indoor PM2.5 concentration is 110μg / m 3 , PM10 concentration is 280μg / m 3 , the negative ion concentration i...

Embodiment 2

[0047] Embodiment 2, the supporting layer 1 selects 304 stainless steel wire mesh with a wire diameter of 0.05mm and 30 meshes, and sprays a single square meter grammage of 15g / m on the upper end surface of the supporting layer 1 2 1. The polyethersulfone resin PES hot-melt adhesive mesh membrane with a pore size of 10 μm is used as the primary filter layer 2, and a negative ion functional membrane with a thickness of 20 μm, which is made of tourmaline powder as the main raw material and added with polyurethane adhesive, is sprayed on the upper surface of the primary filter layer 2 Layer 4.

[0048] Replace the original window screen of the building with the window screen made in this embodiment and carry out the 1-hour window ventilation experiment. The data are as follows:

[0049] Before changing the window screen and opening the window for 1 hour for ventilation, the outdoor PM2.5 concentration was 368 μg / m 3 , the negative ion concentration is 156 / cm 3 ; After opening t...

Embodiment 3

[0051] Embodiment 3, the support layer 1 selects a wire diameter of 0.05mm and 30 mesh polyethylene PE wire mesh, and sprays a single square meter grammage of 9g / m on the end surface of the support layer 1 2 , Polyethersulfone resin PES hot-melt adhesive mesh membrane with a pore size of 20 μm is used as the primary filter layer 2, and then the high polymer polypropylene PP material is used on the primary filter layer 2 to prepare micropores with a pore size of 2 μm by a melt blown process The membrane is used as the secondary filter layer 3, and the support layer 1, the primary filter layer 2, and the secondary filter layer 3 are hot-pressed on a hot press, and then the upper surface of the secondary filter layer 3 is sprayed with tourmaline powder as the main raw material. The thickness of the polyurethane adhesive is the negative ion functional film layer 4 of 10 μm.

Abstract

The invention discloses efficient tiny-dust-proof window gauze capable of releasing negative ions and a manufacturing method of the efficient tiny-dust-proof window gauze. A negative ion functional film layer is attached to the window gauze and is a film layer capable of releasing the negative ions, the film layer is formed by negative ion powder and high polymer materials with the adhesion function in a spraying mode, and therefore the window gauze has the function of releasing the negative ions while being used for filtering dust, the content of the negative ions in air passing the window gauze can be increased, the quality of the air entering a room can be improved, adverse affects caused by outdoor atmospheric pollution on indoor work and life of people are reduced, and body health of people is guaranteed. Besides, on the basis that the negative ions have a special aggregation effect on tiny dust, the dust has positive charges, the negative ions in the air can make the tiny dust aggregated, the tiny dust can settle to become large particles capable of being intercepted by a filtering layer of the window gauze more easily, and the tiny dust intercepting efficiency of the filtering layer of the window gauze can be improved.

Description

technical field [0001] The invention belongs to the technical field of building materials with special functions, and relates to a window screen, in particular to a high-efficiency dust-proof window screen capable of releasing negative ions and a manufacturing method thereof. Background technique [0002] With the rapid development of modern industry and the deteriorating ecological environment, due to the heavy dependence on coal and oil for power energy and the rapid increase in car ownership, air pollution is becoming more and more serious, and haze weather has almost become the norm Globalization poses a huge threat to human health. The quality of air quality generally depends on two main indicators, that is, the concentration of pollutants in the air and the concentration of negative ions in the air. The higher the concentration of pollutants and the lower the concentration of negative ions, the worse the air quality; The lower the concentration and the higher the nega...
