Description
Technical field
The present invention relates to underground engineering, such as the waterproof of civil air defense constructions and installations, culvert, water works, reservoir, ground building are anti-
It seeps.
Background technique
Currently, being directed to underground engineering, such as the waterproof of civil air defense constructions and installations, culvert, water works, reservoir, ground building is anti-
The waterproofing agent of organosilicon material category of infiltration has.
1. methyl silanol salt：Rigidity water-proofing material, when use, can be with the carbon dioxide and water in substrate surface layer and air
Generate chemical reaction, generate water-repellent layer, can pore in plugging cement screed, the density of reinforced mortar improves it
Impermeability, to play waterproof action.But such waterproof material can generate white powdery precipitate in substrate surface, influence to build
Build object surface complexion；In addition, generating silanol under strongly alkaline conditions and loss soluble in water, make waterproof effect under certain condition
It ceases to be in force automatically.
2. silicones class：Such waterproofing agent of organosilicon has excellent resistant of high or low temperature, resistance to ag(e)ing, unique hydrophobicity
With gas permeability, nontoxic corrosion-free, but the waterproof layer glossiness formed is high, not scrubbing resistance, influences the surface complexion of building, and anti-
The effectiveness of water layer cannot keep for a long time.
3. emulsion-type waterproofing agent of organosilicon：Emulsion-type waterproofing agent of organosilicon mainly has following kind：First is that methyl hydrogen silicon
Fat liquor, due to easily being reacted with hydroxyl isoreactivity group containing the hydrogen atom reactivity with higher being connected directly with silicon,
Form netted waterproof membrane；Second is that hydroxy-silicone-oil emulsion, hydroxy-silicone-oil emulsion can directly be emulsified with hydroxy silicon oil or emulsion polymerization system
?.However emulsion intercalation method is always critical issue.
Summary of the invention
The present invention various waterproof materials currently on the market and corresponding construction method there are aiming at the problem that, propose a kind of novel
Modified early strong waterproofing agent of organosilicon factory formula and technique, optimize properties of product.
Formula composition of the invention：Alkylalkoxy silane 70-75%, water 15%, emulsifier 5%, early strength agent 3%, silane are even
Join agent 2%.
The principle of work and power of the invention is：Silanol group and portland cement in modified early strong waterproofing agent of organosilicon molecular structure
Silanol group in material reacts dehydrated crosslinking, to realize that " anti-capillary effect " forms excellent water-repellent layer, significantly improves water
The impermeability of cement mortar and concrete；Meanwhile mix waterproofing agent of organosilicon cement mortar and concrete have micro-expansibility,
The contraction fissure generated in cement hydration process can be reduced, the compactness of cement structures is increased.
The present invention is colourless or weak yellow liquid, and density is in 1.18-1.2, pH value 12+, solid content >=26%.
The production technology embodiment of the modified early strong waterproofing agent of organosilicon of the present invention.
By weight, alkylalkoxy silane 75kg, water 15kg, emulsifier 5kg, early strength agent 3kg, silane coupling agent are taken
2kg is sequentially placed into the blender started, uniform stirring 60 minutes, is shut down, and in blowing to precipitating filtering cloth jar, stands 30 points
Clock, then packing storage, obtains modified early strong waterproofing agent of organosilicon about 100kg.
The construction and application method of the modified early strong waterproofing agent of organosilicon of the present invention.
1. waterproof mortar is constructed：Clear up silt, sundries, the greasy dirt etc. of construction area；The control of the ratio of cement and sand exists
1:2.5 ~ 3 (32.5R grades or more portland cement, middle sand, clay content are less than 3%), ratio≤0.5 of water and cement are modified early
Strong waterproofing agent of organosilicon dosage accounts for the 3 ~ 5% of cement consumption.It, should be first by modified early strong organic silicon water-proofing to guarantee to be uniformly mixed
Agent is uniformly mixed with the water of cement mortar ratio amount and adds water mud and sand.Smear two layers of construction of waterproof layer point（Every layer of 10mm thickness）.Bottom
Plain mortar 1mm is first smeared, then smears waterproof mortar course, is compacted when pre-hardening, is twisted into pitted skin with wooden float；It is caught up with after smearing second layer waterproof mortar
Optical pressure is real（If you need to decoration construction, it is necessary to be twisted into pitted skin）.By the maintenance method sprinkling maintenance of conventional cement mortar.
2. water-proof concrete is constructed：Modified early strong organic silicon water-proofing dosage accounts for the 1% of cement consumption, and uniformly incorporation is prepared mixed
Solidifying soil is identical as normal concrete construction method.It is uniformly mixed to guarantee, it will should first be modified early strong waterproofing agent of organosilicon and mix
The water of solidifying soil proportional quantity, which is uniformly mixed, adds water mud, sand and stone.By the maintenance method sprinkling maintenance of portland cement concrete.
3. spraying impervious construction：Modified early strong waterproofing agent of organosilicon is sprayed at cement structures table after adding 8 ~ 10 times of clear water dilutions
Face, brick, watt, the water absorbing inorganics building material surface such as plasterboard, common coating wall be used for impervious damp-proof treatment, there is excellent waterproof
Impervious effect.
Application places of the invention.
Applied to underground engineering, such as the water proof anti-seepage of civil air defense constructions and installations, culvert, water works, reservoir, ground building.
