Embodiment 1

[0018] In the present invention, cheap natural black tourmaline, zeolite, far-infrared zirconia and titanium dioxide powders are mixed to prepare a mineral microcrystalline composite material, wherein the black tourmaline is produced in the middle of the Maguan-Malipo ore belt in Yunnan, and the main mineral composition and The chemical composition is shown in Table 1 and Table 2. Zeolite, far-infrared zirconia and titanium dioxide powders were purchased from the market, and the main components were Na[AlSi 5 O 12 ]3H 2 O, ZrO 2 and TiO 2 .

[0019] First, the natural minerals black tourmaline and zeolite are respectively rinsed, dried, and pulverized; then, they are mixed according to the following weight percentages: tourmaline microcrystal: zeolite: far-infrared zirconia powder: titanium dioxide powder=60%: 12%: 10%: 18%; ball-milled until the particle size of the powder is about 120 mesh, and then the above-mentioned microcrystalline composite powder is slowly heated ...

Embodiment 2

[0024] The present invention selects and mixes cheap natural black tourmaline, zeolite, infrared zirconia and titanium dioxide powder to prepare a mineral microcrystalline composite material. The chemical compositions are shown in Tables 3 and 4. Zeolite, far-infrared zirconia and titanium dioxide powders were purchased from the market, and the main components were Na[AlSi 5 O 12 ]3H 2 O, ZrO 2 and TiO 2 . First, the natural minerals black tourmaline and zeolite were rinsed, dried and pulverized respectively; then mixed according to the following weight percentages: tourmaline crystallites: zeolite powder: far-infrared zirconia powder: titanium dioxide powder = 65%: 10%: 10 %: 15%; then ball-milled to a particle size of about 100 mesh.

[0025] Then, the above-mentioned microcrystalline composite powder is slowly heated to 450° C. in a box-type heating furnace, kept for 4 hours, and then cooled to room temperature with the furnace to complete the activation treatment of ...

Abstract

The filter material for eliminating cigarette smoke is formed from tourmaline microcrystal, zeolite, far infrared zirconia powder and titania powder according to the mixing ratio of 60-65%:10-15%:10-15% and 15-20%. Its preparation process is as follows: firstly, cleaning tourmaline and zeolite respectively, drying and pulverizing to obtain tourmaline microcrystal and zeolite, mixing them according to the above-mentioned ratio, ball-grinding them to 100-120 meshes, heating at 450-500 deg.c for 3-4 hr, finally mixing the above-mentioned powder material, with plastics and foaming agent according to the ratio of 3:1:0.1, foaming so as to obtain the invented filter material microporous sponge body which not only can be used for elimianting cigarette smoke and cleaning air, but also can release lots of negative ions.

Description

technical field [0001] The invention relates to a microporous sponge filter element composed of a natural mineral microcrystalline composite material, and the invention further relates to a manufacturing process of the filter material. Background technique [0002] In order to meet the comfort requirements, modern homes and carriages are often designed to be closed due to the use of air conditioners, which greatly increases the degree of internal air pollution. Especially when someone smokes, the environment contains a large amount of substances such as tar, CO, nicotine. , dust, and the recently discovered dioxin, etc., are very harmful to the human body. According to statistics, there are nearly 300 million smokers in my country, and the harm of "passive smoking" has attracted great attention from the society. [0003] Although there are some products similar to indoor air purification currently on the market, such as the use of filtration, adsor...
