Environment-friendly material capable of purifying air as well as preparation method thereof

Abstract

The invention discloses an environment-friendly material capable of purifying air. The environment-friendly material comprises base cloth serving as a carrier and a filter medium formed on the base cloth. The filter medium comprises the following components in parts by weight: 65-75 parts of a non-metal ore absorber, 12.5-15 parts of negative ion powder, 12.5-15 parts of far infrared ceramic powder and 8-10 parts of nanosilicon dioxide. The preparation method comprises the following steps: (1) adding a diluent in proportion and mixing and stirring in a mixer to form slurry; (2) adding an emulsion binder into the slurry, and stirring to form milk white shaped slurry; and (3) placing the milk white shaped slurry in a coating groove and adopting a pneumatic mixer to ensure uniform solid and liquid of the slurry and prevent precipitate; (4) dipping the base cloth to the coating groove, wherein the base cloth is fully dipped by the slurry and then enters into an extrusion cylinder to extrude residual slurry, and the base cloth enters into an oven to be roasted and dried; and (5) rolling the dried base cloth through a leveling process for later use. The environment-friendly material has the beneficial effects that the environment-friendly material can stably release negative ions for a long time, and has the functions of sterilizing, removing smell, eliminating passive smoking and improving and purifying indoor air quality.

Description

【Technical field】 [0001] The invention relates to filter materials, in particular to an environment-friendly material capable of purifying air (including waste gas such as second-hand smoke) and a manufacturing method thereof. 【Background technique】 [0002] According to the "China Environmental Status Bulletin", in recent years, my country's urban air quality is still at a relatively heavy level of pollution, the northern cities are heavier than the southern cities, and the annual average concentration of sulfur dioxide is between 3 and 248 μg / m3. The average value is 66 μg / m3, and the annual average value of more than half of the northern cities and more than one-third of the southern cities exceeds the national secondary standard (60 μg / m3), and the annual average value of the northern cities is 72 μg / m3; the southern cities The annual average is 60 μg / m3. The annual average concentration of total suspended particulate matter is in the range of 32-741 micrograms / m3, and 67...
