Abstract
Coal mining spraying fireproof material of a kind of smoke suppressing excellence and preparation method thereof, belongs to fireproof material technical field.By mutually to mix and the polyvinyl alcohol flame-retardant material stirred and ammonium molybdate form, wherein, each compositions in weight percentage is: the polyvinyl alcohol flame-retardant material of 60-80%, the ammonium molybdate of 20-40%; Described polyvinyl alcohol flame-retardant material reacts gained by the mineral aggregate of 3%-7% polyvinyl alcohol, 1%-4% phosphoric acid, 1%-4% urea, 8%-25% white glue with vinyl, 17%-33% and tap water; Described mineral aggregate is one or more arbitrary combination in kaolin, talcum powder, mica powder.The present invention substantially increases the smoke suppressing of material, only has micro-film to produce in combustion processes.
Description
Technical field
Coal mining spraying fireproof material that the present invention relates to a kind of smoke suppressing excellence and preparation method thereof, belongs to fireproof material technical field.
Background technology
Coal in China is occupied an leading position in China energy general layout, very large strategic importance is had to China, huge interests are brought to the country and people, but China's coal-mine field conditions is complicated, bad environments, annual various accident all can cause huge economy and property damage to country, and these accidents have brought huge body and mind injury and menticide.After seam mining, the air quantity between ground and intake and between intake and return aircourse, between return aircourse and ground exchanges and becomes large gradually, and goaf air leaking is serious.The increase of air quantity brings the hidden danger of gas explosion and spontaneous combustion of coal seam.Because a denier air enters coal body inside, the spontaneous compound of coal oxygen releases amount of heat, and this heat is accumulated under certain accumulation of heat condition, when the heat gathered can meet the needs of Coal Self-ignition Process development, coal temperature constantly rises, and finally causes spontaneous combustion of coal.Therefore, process upper and lower two ends, worked-out section and lose the key that ribbing, isolation worked-out section and face up and down trough, worked-out section wind leaking stoppage are fully mechanized coal face prevention of Spontaneous Ignition.Spraying leak stopping preventing and extinguishing fire technology develops very fast in recent years, now having generally applying without coal column fully mechanized coal face of spontaneous fire.At face up and down trough, stop adopting near line and leak out place serious and adopt spraying leakage stopping technology application property good, wind leaking stoppage ability is strong, obviously can reduce the hidden danger of spontaneous combustion of coal seam and gas explosion.Be that the spray material of major ingredient is applied in colliery and carries out the process of coal body wind leaking stoppage and can play effect that is fire-retardant, wind leaking stoppage with polyvinyl alcohol.
But this type of material produces a large amount of smog in one-tenth carbon process, still has certain potential safety hazard in coal-mine fire.
Summary of the invention
Object of the present invention is intended to overcome above shortcoming, proposes a kind of fire-retardant, smoke suppressing effect significant coal mining spraying fireproof material.
The present invention is achieved through the following technical solutions:
A coal mining spraying fireproof material for smoke suppressing excellence, by mutually to mix and the polyvinyl alcohol flame-retardant material stirred and ammonium molybdate form, wherein, each compositions in weight percentage is: the polyvinyl alcohol flame-retardant material of 60-80%, the ammonium molybdate of 20-40%; Described polyvinyl alcohol flame-retardant material reacts gained by the mineral aggregate of 3%-7% polyvinyl alcohol, 1%-4% phosphoric acid, 1%-4% urea, 8%-25% white glue with vinyl, 17%-33% and tap water; Described mineral aggregate is one or more arbitrary combination in kaolin, talcum powder, mica powder.
Polyvinyl alcohol flame-retardant material described above reacts gained by 5% polyvinyl alcohol, 1.6% phosphoric acid, 1.6% urea, 16.7% white glue with vinyl, the mineral aggregate of 16.7% and the tap water of 58.4%.
A preparation method for the coal mining spraying fireproof material of smoke suppressing excellence, concrete steps comprise:
A) under water-bath, polyvinyl alcohol is joined abundant stirring and dissolving in tap water, temperature controls at 90 DEG C, stirs 5h;
B) phosphoric acid and urea are joined after mixed dissolution in the solution of a) step gained in tap water, react under the bath temperature of 85 DEG C, reaction times 5h;
C), after reacting completely, when solution cool to room temperature, add white glue with vinyl be stirred well to evenly;
D) to step c) mineral aggregate that adds in the fire resistant fluid of gained fully stirs 2h;
E) to steps d) add ammonium molybdate in the fire retardant material of gained, stir 2h, wherein polyvinyl alcohol flame-retardant material accounts for mass ratio 60-80%, and ammonium molybdate accounts for mass ratio 20-40%.
The coal mining spraying fireproof material of a kind of smoke suppressing excellence of the present invention, has following significantly advantage:
1. its spraying coating process of coal mining spraying fireproof material of a smoke suppressing excellence and the spraying coating process of polyvinyl alcohol flame-retardant material completely the same, other spraying coating process need not be reselected;
2. substantially increase the smoke suppressing of material, in combustion processes, only have micro-film to produce;
3. improve the flame retardant properties of material;
