Description
Technical field
The present invention relates to a kind of grout material and preparation method thereof, in particular to a kind of inorganic salts waterproofing and leakage-stopping consolidation grouting material
And preparation method thereof.Belong to material for construction engineering field.
Background technique
Common grouting amount mainly has currently on the market: sodium metasilicate class, cement base class, polyurethanes, Acrylates, ring
Oxygen resinae etc..But the properties of product of these classes are single, application range is small, durability is poor, polyurethane, acrylates, asphalt mixtures modified by epoxy resin
Lipid product smell is big, it is toxic, harmful, environmentally protective technical requirements are not achieved.
In addition, the grout material of organic is although flexible, but intensity is low, durability is poor in these traditional grout materials,
Can only cementation of fissures leak stopping, and do not have the effect of reinforcing, therefore this kind of grout material " can only treat the symptoms " and " cannot effect a permanent cure ", be not achieved long-term
The effect of waterproofing and leakage-stopping.Although the grout material of inorganic has that intensity, durability are good, but exist without elasticity, water imbibition and expansion
The problems such as property, be a kind of material of perfect rigidity.This kind of grout material cannot resist differential settlement and the vibration of engineering, once have
Sedimentation and vibration will receive destruction consequently also to be broken, therefore do not have the effect of waterproof.
With the rapid development of economic construction of China, more stringent requirements are proposed in terms of construction quality construction, especially
In civil buildings underground engineering, mining tunnel, subway engineering, underground pipe gallery engineering etc. in terms of construction and later period maintenance maintenance,
Urgent need one kind can waterproofing and leakage-stopping and reinforce functional, compound grout material.Therefore this respect research and development of products at
For the hot spot of this field.
Inorganic salts waterproofing and leakage-stopping consolidation grouting material of the invention is based on a kind of function of inventing under this technical background
The compound grout material of property.The present invention solves the deficiency of existing product, has reached elastic performance big, intensity is high, durability is good,
Have the function of that water imbibition is strong, expansion rate is big, solid water amount is big, consolidation force is strong, " infuse into, stifled firm, solid long " can be played
Act on and reach the performance of " sand is not walked, Shi Budong, water do not flow ".
Summary of the invention
The technical problem to be solved in the present invention is to provide one kind have high resiliency, high intensity, water absorption rate are strong, solid water amount is big,
Consolidation force is good, durability is good, have a wide range of application, adaptive surface is wide, has both had waterproofing and leakage-stopping performance but also with the function of reinforcement performance
Energy compound grout material of property and preparation method thereof.
In order to reach above-mentioned purpose, the present invention provides a kind of inorganic salts waterproofing and leakage-stopping consolidation grouting material, is expected by the A of independent packaging
Expect that two parts form with B, row mixing again when to be used, the A material is fluent material, comprising: 45~70 parts by weight of water, acrylic acid
10~40 parts by weight, 10~30 parts by weight of lotion, 5~10 parts by weight of triethanolamine；The B material is powder body material, comprising: oxidation
50~70 parts by weight of magnesium, 10~30 parts by weight of SILICA FUME, 10~30 parts by weight of acrylic resin, 2~5 weight of methylene diacrylamide
Measure part, 2~5 parts by weight of ammonium persulfate.Wherein, general in for A material and B material by the revealed each material rate of parts by weight.
Preferably, the A material includes: 65 parts by weight of water, 15 parts by weight of acrylic acid, 10 parts by weight of lotion, 5 weight of triethanolamine
Measure part；The B material includes: 65 parts by weight of magnesia, 15 parts by weight of SILICA FUME, 15 parts by weight of acrylic resin, the double propylene of methene
2 parts by weight of amide, 3 parts by weight of ammonium persulfate.
Preferably, the lotion be selected from acrylic emulsion, organosilicon rubber emulsion, styrene-acrylic emulsion, silicone acrylic emulsion wherein it
One or combinations thereof；It is furthermore preferred that the lotion is acrylic emulsion.
The present invention also provides the preparation methods of above-mentioned grout material, comprising the following steps:
1) preparation of A material
The A material for preparing parts by weight of the present invention is raw materials used, adds water in stirred tank, and acrylic acid is added and stirs certain time
