Problems solved by technology

[0002] At present, comprehensive dust prevention technology and fire prevention technology in coal mining, dust suppression technology in open-pit mine roads, flame retardant and dust suppression technologies in port coal piles, etc. Dust suppression materials such as sticky dust flame retardants also have certain effects in practical applications, but there are many disadvantages, such as high corrosiveness, and their corrosion rate is as high as 0.25mm / a to 0.3mm / a. Iron products, paint and leather all have serious corrosion hazards, which greatly limits its application range. In addition, the viscosity of its sticky dust is not large enough, and its fire prevention and dust suppression effect is not ideal. the solution

Embodiment 1

[0010] Use 60% calcium chloride dihydrate, 20% magnesium chloride hexahydrate, and 20% water as the main ingredients, heat it to 200°C in the reactor, and introduce it into the grid mixer. The main material is mixed with auxiliary materials with a mass of 1% of the main material; the high-temperature product after mixing is introduced into a cooling slicer, and after being sliced ​​by cold water, it is a scaly product.

Embodiment 2

[0012] Use 55% calcium chloride dihydrate and 45% water as raw materials, take 100kg of the above materials, add 1000g of surfactant compound and stir at 180°C, wherein the wetting agent nonylphenol polyoxyethylene ether 0π -10 is 588g, dispersant MS-1 is 118g, corrosion inhibitor M2 is 294g, dodecyldimethyl benzyl ammonium chloride 1227 is 100g, after the reaction is finished, condense, under dry conditions, crush and sieve, That is, it is made into a powder product.

Embodiment 3

[0014] Use 55% magnesium chloride hexahydrate and 45% water as raw materials, take 1000kg, and add 600g of surfactant compound at 220°C, wherein fatty alcohol polyoxyethylene ether level plus 0 is 292g, corrosion inhibitor M2 is 16g, Lauryl dimethyl benzyl ammonium chloride 120g, dispersant soap calcium dispersant dosage 36g, after stirring and reacting, condense, crush under dry conditions, sieve, add water to form an ointment product.

Abstract

The invention relates highly effective fireproof dust suppression material and method. The material comprises 60% calcium chloride dehydrate, 20% magnesium chloride hexahydrate, 20% water and surface active agent. The surface active agent comprises wetting agent, dispersing agent and inhibitor. The calcium chloride-dehydrate and magnesium chloride hexahydrate have hydroscopicity and fire-retardancy, and the surface active agent has the advantages of reducing surface tension, humectation and thickening action. The invention has the advantage of reducing corrosion. It can be used in anti-dust, fireproof fields.

Description

Background technique [0001] The present invention relates to the fields of comprehensive dust prevention technology, fire prevention technology, road surface dust suppression in open-pit mines, flame retardant and dust suppression of coal piles in ports, etc. Dust material and synthesis method. Background technique [0002] At present, comprehensive dust prevention technology and fire prevention technology in coal mining, dust suppression technology in open-pit mine roads, flame retardant and dust suppression technologies in port coal piles, etc. Dust suppression materials such as sticky dust flame retardants also have certain effects in practical applications, but there are many disadvantages, such as high corrosion rate, and the corrosion rate is as high as 0.25mm / a to 0.3mm / a, which is not suitable for general Iron products, paint and leather all have serious corrosion hazards, which greatly limits its application range. In addition, the viscosity of its sticky dust is n...
