Anti-haze spray for improving haze filtering capacity of mask

Abstract

The invention discloses an anti-haze spray for improving the haze filtering capacity of a mask. The anti-haze spray is prepared from, by weight, 4-6 parts of N,O-carboxymethyl chitosan, 3-5 parts of sodium alginate, 2-4 parts of ethyl alcohol, 1-3 parts of copper sulfate, 80-100 parts of water and 4-6 parts of diethylenetriamine pentaacetic acid and glycerin, wherein the ratio of the weight part of diethylenetriamine pentaacetic acid to the weight part of glycerin is (3-5):1. The anti-haze spray further comprises lysozyme, and the concentration of lysozyme is 400,000-600,000 per gram, in other words, 400,000-600,000 pieces of lysozyme are contained per gram of the anti-haze spray. When the spray is sprayed, the filtering capacity of the common mask for PM2.5 can be remarkably improved. The anti-haze spray will not affect the breathability of the mask. The anti-haze effect of the anti-haze spray may be related with the ratio of the weight part of diethylenetriamine pentaacetic acid to the weight part of glycerin in the formula.

Description

technical field [0001] The invention belongs to the field of health care and relates to an anti-haze spray, in particular to an anti-haze spray for improving the ability of a mask to filter PM2.5 in haze. Background technique [0002] Haze is a combination of fog and haze. Smog is common in cities. In many areas of China, fog is combined with haze as a disastrous weather phenomenon for early warning and forecasting, collectively referred to as "smog weather". [0003] Smog is the result of the interaction between specific climatic conditions and human activities. The economic and social activities of a high-density population will inevitably emit a large amount of fine particulate matter (PM2.5). Once the emission exceeds the atmospheric circulation capacity and carrying capacity, the concentration of fine particulate matter will continue to accumulate. Widespread smog. [0004] In 2013, "smog" became the keyword of the year. In January of this year, 4 times of smog cov...
