Abstract
The invention discloses a kind of inorganic modified polyurethane grouting material, including component A and B component, the component A includes the component of following parts by weight：85~98 parts of dimethylethanolaminesolution solutions, 0.5~3 part of lauric acid diethyl amide, 1~5 part of dimethylethanolamine, 0~8 part of water；The B component includes the component of following parts by weight：10~80 parts of sodium methyl silicates, 10~75 parts of butyl titanates, 5~20 parts of chloroforms, 5~15 parts of phosphoamides of saturation 18.The material preparation method of the present invention is simple, and material is injected in coal and rock by Double-liquid mud-injection pump, and the function of reinforcing coal and rock can be reached after rapid curing；Material has relatively low maximum temperature, splendid fire resistance and relatively low cost compared with conventional polyurethanes grouting material, and mechanical property can also be maintained at higher level, and the advantages that remain under water environment to keep higher intensity；Material is free of toxic volatile and corrosive substance, meets safety and environmental requirement of the underground to material.
Description
Technical field
The invention belongs to chemical technology field, more particularly to a kind of inorganic modified polyurethane grouting material and its preparation side
Method.
Background technology
Coal mine roadway frequently can lead to the hair of the coal mining accidents such as roof fall, wall caving in tunneling process, broken or loose coal and rock
It is raw, not only seriously jeopardize the life security of absence from work without reason, but also had a strong impact on the production efficiency of coal mining enterprise.Therefore, colliery exists
In production process, will typically grouting and reinforcing be carried out to fractured coal and rock.Injecting paste material species is more, there is inorganic injecting paste material
With point of organic injecting paste material.Widely used mineral-type materials are waterglass cement two-shot groutings, and material advantages are
Cost is low, reacts not heat release substantially, but curing rate is slow, and compression strength and adhesion strength are low, permeability and poor toughness.Organic
What grouting material was most widely used is polyurethane grouting material, and material solidification speed is adjustable, and compression strength and adhesion strength are good,
Permeability and good toughness, consolidation effect will be significantly better than mineral-type materials, but product cost is high, and exothermic heat of reaction amount is big, fire-retardant
Property is bad, easily causes the generation of secondary disaster, and material has a foaming of larger multiplying power in water environment, and the strength of materials is notable
Reduce, so as to considerable influence consolidation effect.
The content of the invention
In view of the shortcomings of the prior art, it is and normal it is an object of the invention to provide a kind of inorganic modified polyurethane grouting material
Rule polyurethane grouting material, which is compared, has relatively low maximum temperature, splendid fire resistance and relatively low cost.
To achieve these goals, technical scheme is as follows：
The invention provides a kind of inorganic modified polyurethane grouting material, including component A and B component,
The component A includes the component of following parts by weight：
85~98 parts of dimethylethanolaminesolution solutions, 0.5~3 part of lauric acid diethyl amide, 1~5 part of dimethylethanolamine, 0~8
Part water；
The B component includes the component of following parts by weight：
10~80 parts of sodium methyl silicates, 10~75 parts of butyl titanates, 5~20 parts of chloroforms, 5~15 parts of phosphinylidynes of saturation 18
Amine.
The present invention compared with prior art, has advantages below and beneficial effect：
1st, component A and B component all have relatively low viscosity in material of the invention, good penetrability, can penetrate into trickle coal petrography
In body crack.
2nd, material solidification speed of the invention can be big come condition, regulation section according to requirement of engineering.
3rd, material of the invention adds substantial amounts of inorganic material, and anti-flammability is splendid, close to non-ignitable rank.
4th, the content of material of the invention because reducing reactive group, exothermic heat of reaction amount substantially reduce, maximum temperature
Less than 100 DEG C.
5th, material of the invention does not foam under water environment, can effectively ensure that material body intensity.
6th, material of the invention is mainly used in the advanced of colliery digging laneway breaking roof, the reinforcing of country rock and working face
The field such as reinforce, be particularly suitable for use in highly gassy mine and the shorter colliery of spontaneous combustion time.
7th, material of the invention is mainly used in the reinforcing of colliery fractured coal and rock and tomography, prevents top plate roof fall and wall caving thing
Therefore generation；Material is composite modified to the progress of organic polyurethane grouting material by inorganic silicic acid salting liquid, makes material while has
The advantages of standby organic material and inorganic material, material not only have higher compression strength, tensile strength and an adhesion strength, and because
The addition of inorganic material makes the cost of material obtain larger reduction, and anti-flammability is also greatly improved, material exothermic amount
Also significantly reduced, and in the case where there is water condition, foamable reaction will not also occur for material, and the strength of materials can obtain effectively
Ensure, substantially increase the application security of material.
Embodiment
The present invention is described in detail below in conjunction with specific embodiment, herein illustrative examples and explanation of the invention
For explaining the present invention, but it is not as a limitation of the invention.
