Problems solved by technology

[0007] Based on the technical problems existing in the background technology, the present invention proposes a haze inhibitor and its preparation method, aiming to solve the problems that dust cannot be effectively solidified and the existing dust inhibitors are not suitable for municipal facilities or will cause secondary pollution. Problems, ensure that it does not affect municipal facilities and travel safety after use, can be absorbed by plants, can be naturally degraded after entering water bodies, and does not cause harm to aquatic organisms

[0035] Preparation of CPAM:

[0036] In the reaction kettle equipped with stirrer, thermometer, reflux condenser and gas conduit, add the designed amount of AM and DMC (fixed mass ratio is AM:DMC=3:1~4:1), urea, EDTA-2Na and Deionized water, at a speed of 60r / min, pass through N 2 Stir for 30min;

[0037] The metered redox initiator (fixed mass ratio is (NH 4 ) 2 S 2 o 8 :NaHSO 3 =1:1) was formulated into a 1% aqueous solution, added to the reactor, and a certain amount of AIBN was added at the same time; the reaction temperature was raised to 30°C, and at a speed of 60r / min, the 2 Stir for 30min; stop feeding N 2 , quickly seal the reactor, react at 30°C for 3.5h, adjust the reaction temperature to 50°C, and continue to stand for 2h to obtain a transparent jelly product; place the jelly in an oven at 60°C for 48h, and dry the The solid is pulverized to obtain powdered CPAM.

[0038] The preparation process of a typical cationic polyacrylamide is described as follows:...

Embodiment 1

[0043] 5kg CPAM, 1kg CaCl 2 , 3kg polyethylene glycol-200, 2kg sodium lauryl sulfate and 89kg tap water were added in a 200L reactor, dissolved and mixed evenly under stirring conditions, to obtain the smog inhibitor.

Embodiment 2

[0045] 7kg CPAM, 2kg CaCl 2 , 4kg of glycerin, 1kg of sodium dodecylsulfonate and 86kg of tap water were added to a 200L reactor, dissolved and mixed evenly under stirring conditions to obtain the smog inhibitor.

Abstract

The invention discloses a haze inhibitor. The haze inhibitor comprises cationic polyacrylamide, a calcium salt, polyol or polyacid salt, a penetrant and water. The cationic polyacrylamide (CPAM) used in the invention has good water solubility, fast dissolving speed, strong water absorption and strong water retention, and can maintain the humidity of an application position; the CPAM has various reactive groups, and the CPAM and various substances, such as aerosol and tiny dusts in air undergo an affinity action to adsorb, agglomerate and coagulate the various substances in order to form block substances, so afresh dust flying is prevented; the calcium salt and the polyol or polyacid salt used in the invention respectively have good moisture retention, have a bridging effect in the formula, and can well link particles; the haze inhibitor can be absorbed by plants, has no damages to vegetations and dose not cause secondary pollution to environment; and a preparation method of the haze inhibitor is simple, can be locally implemented in municipal administration and environmental protection works, and is easy to promote.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a haze inhibitor and a preparation method thereof. Background technique [0002] Smog has always been accompanied by people's production and living activities, which will have a serious impact on the human body. With the intensification of human activities, smog is getting worse. In most parts of northern my country and parts of the Sichuan Basin, smog has seriously affected people's lives and endangered people's physical and mental health, and even life safety. Relevant national departments have invested a lot of funds and energy in the control of smog, and introduced many control measures, which have achieved certain results, but the smog is still serious. [0003] There is a phenomenon that deserves special attention, that is, after rain and humid and cold air, the smog suddenly decreases, and the air quality immediately becomes good or even excellent.
