Problems solved by technology

This treatment method has quick effect, no pollution, and is not easy to leave dead spots, but the negative ion itself has a short life span, and its existence in the air is only a flash in the pan (the life span in clean air is a few minutes, and it is only a few seconds in a dusty place). Fleeting
Therefore, although negative oxygen ions can improve lung function and give people a relatively fresh feeling, they are helpless in the long-term treatment of indoor pollutants, and the effect is very limited.

Abstract

The invention discloses an air-purifying particle composition and a preparation method of the air-purifying particle composition, wherein the composition contains the components in parts by weight: 50 to 80 parts of tetra-needle like zinc oxide whisker, 10 to 45 parts of 13X molecular sieve and 5 to 10 parts of magnesium phosphate; the preparation method comprises the steps of: uniformly mixing the components in a mixing agitator according to the proportion, pelletizing pellets with the grain size from 2 to 5mm in a pelletizer, and then drying the pellets in a baking oven at 280 to 300 DEG C for 3 to 5 hours to obtain the particle composition. The composition has the advantages of strong air purifying performance, stable effect, constant and repeatable air purification, no need of photocatalysis, wide applicable scope and being convenient in use.

Description

technical field [0001] The invention relates to an air purification material and a preparation method thereof, in particular to an inorganic composite air purification material capable of adsorbing and decomposing harmful gases and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and society and the continuous improvement of people's living standards, more and more volatile indoor environmental pollutants from various decorative materials and daily chemicals have entered residential and public buildings, resulting in the pollution of the living environment. Dramatic increase. According to the survey, 80% of newly-decorated houses and 90% of newly-decorated offices in my country have excessive harmful pollutants. Since most people spend more than 80% of their lives indoors, it is self-evident that indoor environmental pollution causes harm to people's health and population quality. According to statistics from the...
