Problems solved by technology

On November 12, 2013, the communiqué of the "Third Plenary Session of the 18th Central Committee" of the Party once again focused on the construction of ecological civilization, and proposed that the red line of ecological and environmental protection should be guaranteed by institutionalization. However, a large number of smog control policies are aimed at Regulations and policies, or some simple preventive measures like anti-smog masks, do not really have products that address the hazards of smog and haze, and products that comprehensively control smog on a large scale

Abstract

The invention discloses a natural degradable macromolecule haze suppressing spray agent as well as a preparation method and application thereof, belonging to the technical field of air pollution control. Including weighing 4 to 8 parts of sodium hydroxide solution of a certain concentration, 0.1 to 2 parts of humic acid solution, 2 to 7 parts of lignin solution, 0.12 to 0.4 parts of potassium persulfate solution, and nitrogen nitrogen methylenebisacrylamide solution 0.03 to 0.1 parts, 0.01 to 0.08 parts of nano-silver solution, 8 to 13 parts of acrylic acid, add sodium hydroxide solution to acrylic acid under ice water bath and stir, and place in ice water bath to obtain a reaction solution; put humic acid solution, wood Add plain solution, potassium persulfate solution, nitrogen nitrogen methylene bisacrylamide solution, nano-silver solution and reaction solution into the reactor, stir evenly and adjust the pH, after microwave reaction, filter, wash, dry and pulverize to prepare get the product. The method requires low equipment and is environmentally friendly. The prepared product can absorb smog gas and particulate matter, optimize air quality, and can fertilize the soil when it falls on the ground or soil.

Description

technical field [0001] The invention belongs to the technical field of air pollution control, and in particular relates to a natural degradable macromolecule haze suppression spray agent and its preparation method and application. Background technique [0002] Since 2013, atmospheric smog has swept across the country. Smog does not simply stay in the aspects of climate, environment, traffic, etc., but has already "taken root in the hearts of the people" and directly threatens human health. On September 12, 2013, the State Council issued the Action Plan for Air Pollution Prevention and Control. According to the calculation of the Ministry of Environmental Protection, if the plan is fully implemented, nearly 90,000 premature deaths can be reduced each year, accounting for about 20% of the premature deaths caused by air pollution in my country. It can be seen that smog has become the "new killer" of human health. Smog hurts the liver, heart, blood, lungs, and spirit. In addit...
