Abstract
A kind of colourless or faint yellow water-soluble waterproof material of rigidity, silanol group in modified penetrant crystalline waterproofing agent of organosilicon molecular structure reacts dehydrated crosslinking with the silanol group in portland cement material, to realize that " anti-capillary effect " forms excellent water-repellent layer, the impermeability of cement mortar and concrete is significantly improved；Simultaneously, the cement mortar and concrete of incorporating modified penetrant crystalline waterproofing agent of organosilicon have micro-expansibility, the contraction fissure generated in cement hydration process can be reduced, increase the compactness of cement structures, modified penetrant crystalline waterproofing agent of organosilicon can penetrate into concrete pore the hole for forming a large amount of insoluble crystal blocking concrete simultaneously, and infringement of the sulfate to concrete can be reduced, waterproof protective is played the role of.It is mainly used in underground engineering, such as the water proof anti-seepage of civil air defense constructions and installations, culvert, water works, reservoir, ground building.
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
Modification penetrant crystalline waterproofing agent of organosilicon factory formula and technique, optimize properties of product.
Formula composition of the invention：Alkylalkoxy silane 75%, sodium methyl silicate 10%, emulsifier 5%, triethanolamine 3%,
Early strength agent 3%, silane coupling agent 2%, carboxymethyl cellulose 1%, surfactant 1%.
The principle of work and power of the invention is：Silanol group and silicate in modified penetrant crystalline waterproofing agent of organosilicon molecular structure
Silanol group in cement material reacts dehydrated crosslinking, to realize that " anti-capillary effect " forms excellent water-repellent layer, significantly mentions
The impermeability of high cement mortar and concrete；Meanwhile the cement mortar and concrete for mixing waterproofing agent of organosilicon are with micro- swollen
Swollen property, can reduce the contraction fissure generated in cement hydration process, increase the compactness of cement structures, while modified infiltration knot
Brilliant waterproofing agent of organosilicon can penetrate into concrete pore the hole for forming a large amount of insoluble crystal blocking concrete, and can subtract
Few infringement of the sulfate to concrete, plays the role of waterproof protective.
The present invention is colourless or weak yellow liquid, and penetrating power is strong, and hydrophobicity is good, and water absorption rate is low, environmentally friendly.
The production technology embodiment of the modified penetrant crystalline waterproofing agent of organosilicon of the present invention.
By weight, alkylalkoxy silane 75kg, sodium methyl silicate 10kg, emulsifier 5kg, triethanolamine 3kg are early
Strong agent 3kg, silane coupling agent 2kg, carboxymethyl cellulose 1kg, surfactant 1kg are sequentially placed into the blender started,
It uniform stirring 60 minutes, shuts down, in blowing to precipitating filtering cloth jar, stands 30 minutes, then packing storage, obtain modified infiltration knot
Brilliant waterproofing agent of organosilicon about 100kg.
The construction and application method of the modified penetrant crystalline 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 to seep
Crystallization waterproofing agent of organosilicon dosage accounts for the 3 ~ 5% of cement consumption thoroughly.To guarantee to be uniformly mixed, first modified penetrant crystalline should be had
Machine silicon waterproofing 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
It is thick）.Bottom first smears plain mortar 1mm, then smears waterproof mortar course, is compacted when pre-hardening, is twisted into pitted skin with wooden float；Smear second layer waterproof
Catch up with optical pressure real after mortar（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 penetrant crystalline organic silicon water-proofing dosage accounts for the 1% of cement consumption, and uniformly incorporation is matched
Concrete processed is identical as normal concrete construction method.To guarantee to be uniformly mixed, first modified penetrant crystalline organosilicon should be prevented
Aqua is uniformly mixed with the water of concrete matched proportion and adds water mud, sand and stone.By the maintenance method of portland cement concrete
Sprinkling maintenance.
3. spraying impervious construction：Modified penetrant crystalline waterproofing agent of organosilicon is sprayed at cement knot after adding 8 ~ 10 times of clear water dilutions
Structure surface, brick, watt, the water absorbing inorganics building material surface such as plasterboard, common coating wall be used for impervious damp-proof treatment, have excellent
Water proof anti-seepage 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.
