Environmental protection material capable of purifying air

Abstract

An environmental protection material capable of purifying air comprises the following raw materials by weight: 65-75 parts of a non-metallic mine adsorbent, 12.5-15 parts of negative ion powder, 12.5-15 parts of far infrared ceramic powder, 10-16 parts of a mixed solvent, 1-6 parts of hollow glass beads, 2-3 parts of graphite powder and 8-10 parts of nano silica. The environmental protection material can stably release negative ions for long term, and can sterilize, remove peculiar smell, eliminate secondhand smoke, improve and purify indoor air quality.

Description

technical field [0001] The invention relates to a filter material, in particular to an environment-friendly material capable of purifying air (including waste gas such as second-hand smoke). Background technique [0002] The "China Environmental Status Bulletin" shows that in recent years, my country's urban air quality is still at a relatively heavy pollution level, with northern cities being heavier than southern cities, and the annual average concentration of sulfur dioxide in the range of 3 to 248 μg / m3, the national annual average The annual average value of more than half of the northern cities and more than one-third of the southern cities exceeded the national secondary standard (60 μg / m3), and the annual average value of the northern cities was 72 μg / m3; The mean value was 60 μg / m3. The annual mean concentration of total suspended particulates is between 32 and 741 micrograms / m3, and there are 67 cities that exceed the national secondary standard (200 micrograms / m3),...

Problems solved by technology

However, the flue gas filtration catalytic material made of sepiolite cannot be self-cleaning, and the adsorbed colloid and sol compound particles adhere to the surface of the catalyzed filter medium, which affects the continuation of the adsorption process and lowers the overall The adsorption capacity and the adsorption efficiency also decrease with the
