Problems solved by technology

These masks that can filter PM2.5 are usually sold at a higher price, and different brands of masks have great differences in their ability to filter PM2.5
Although ordinary masks are cheap, they cannot filter PM2.5 at all, and cannot prevent haze

Abstract

The invention discloses a haze-proof spraying agent and a preparation method thereof. The haze-proof spraying agent is prepared from the following components in parts by weight: 6-8 parts of N-trimethyl chitosan, 4-6 parts of hydroxypropyl chitosan, 1-3 parts of ethanol, 2-4 parts of radix scutellariae extract, 2-4 parts of copper sulfate, 70-90 parts of water, and 4-6 parts of sodium glucoheptonate and polyethylene glycol at the weight ratio of (3-5) to 1; and the haze-proof spraying agent further comprises lysozyme, and the concentration of the lysozyme is 0.4-0.6 million units per gram, that is to say, each gram of the haze-proof spraying contains 0.4-0.6 million units of the lysozyme. When the spraying agent provided by the invention is sprayed, the PM2.5 filtering capability of common masks can be remarkably improved. The haze-proof spraying agent does not influence the air permeability of the masks. The haze-proof effect of the haze-proof spraying agent is possibly related with the weight part ratio of the sodium glucoheptonate to the polyethylene glycol in the formula.

Description

technical field [0001] The invention belongs to the field of health care, and in particular relates to an anti-haze spray and a preparation method thereof. Background technique [0002] The essence of Fog Thunder. Fog Ting is the general term for fog and Ting. The aerosol system composed of dust, sulfuric acid, nitric acid and other particles in the air causes visual impairment. It is generally believed that when the air humidity reaches more than 90%, it is fog, and if it is less than 90%, it is fog. Fog is a general expression of the excessive content of various suspended particulate matter in the atmosphere. It is a state of air pollution. PM2.5 (full name in English is particulatematter), which is a solid or liquid particulate matter with a diameter of less than or equal to 2.5 microns in the atmosphere. It is considered to be the "culprit" of the fog and thunder weather. Hazards of Fog Thunder. The problem of smog not only plagues the large and medium-sized cities ...
