Embodiment 1

[0038] Under normal temperature and normal pressure, formulate the mist making agent according to the components specified in Table 1 below, including the following steps:

[0039] Step 1: Weigh 85.9wt% water and 11.5wt% smoking agent in a container by mass percentage, stir evenly, and prepare solution 1, wherein the smoking agent is composed of polyethylene glycol-400, tetraethylene glycol, isoethylene glycol Propanol, n-amyl alcohol, sec-hexanol and n-heptanol are compounded according to the mass ratio of 20:15:15:20:20:10;

[0040] Step 2: Weigh 0.1wt% dispersant in solution 1 by mass percentage, stir evenly, and prepare solution 2, wherein the dispersant is OP-10, AEO-9, Tween80, K12 at a mass ratio of 25:25:35:15 compounded;

[0041] Step 3: Weigh 2.5wt% stabilizer in solution 2 according to mass percentage, stir evenly, and obtain a novel high-efficiency, safe and environmentally friendly water-based fog-making agent. Wherein the stabilizer is amyl formate, ethyl aceta...

Abstract

The invention provides a new type of high-efficiency, safe and environment-friendly water-based fog-making agent. ~94wt%. The novel high-efficiency, safe and environmentally friendly water-based fog-making agent introduces an appropriate amount of a specific dispersant into the fog-making agent to prepare an emulsion, so that the stabilizer is uniformly and stably dispersed in the fog-making agent for a long time, and ensures that the fog-making agent is heated by the fog machine. Afterwards, it can be vaporized and sprayed evenly according to the original proportion. The introduction of the dispersant can play the role of the stabilizer more efficiently, improve the stability of the mist, increase the content of water in the fog-making agent, and reduce the content of the smoke-generating agent in the fog-making agent. The novel high-efficiency, safe and environmentally friendly water-based fog-making agent has the characteristics of high water content, low preparation cost, simple preparation process, convenient storage and transportation, safety, environmental protection, etc. It has good application value in the fields of environmental simulation and simulation.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and relates to a fog-making agent, in particular to an efficient, safe and environmentally friendly water-based fog-making agent. Background technique [0002] At present, in the field of crop protection from cold and frost, the burning of sawdust, waste diesel oil, etc. is generally used to generate smoke for heat preservation, but the smoke and dust generated by burning a large amount of smoke-forming substances are more serious pollution to the atmospheric environment, and oil-based aerosols such as diesel oil are used as the base liquid The formation of smoke to protect crops from cold and frost also has the problems of short stabilization time, serious environmental pollution, and high cost of use; most of the aerosols used in the field of pesticide spraying are oil-based aerosols based on diesel oil, etc., which have high flammability, so Fog formation has problems such as explosion safety haz...
