Acid salt cement and using volcanic ash or latent hydraulicity material and other active materials as multiple series such as the cement of key component
Kind.
Cement is not only simply to dose relationship in polymer emulsion, it can send out with the moisture in polymer emulsion
Raw hydration reaction, obtained hydrated product form stable system with polymer emulsion, and the forming process of this system is substantially such as
Under：
A. when polymer emulsion is with cement mixing, cement is uniformly dispersed in polymer emulsion (with acrylate breast
For liquid), occur hydration reaction immediately, the chemical equation of essential mineral is as follows in cement：
3CaO·SiO2(or 3CaOSiO2)+H2O→C-S-H+Ca(OH)2→Ca2++2OH-
B. in acrylic acid ester emulsion contain a large amount of ester group COO-, when with Ca (OH)2When contact, the Ca (OH) of dissolving2's
OH- promotes hydrolysis of ester group, and following chemical reaction occurs：
C. the carboxylic acid ion RCOO- generated after hydrolysis of ester group can be with Ca2+It is combined with ionic bond, in C-S-H gel surfaces
Or Ca (OH)2Plane of crystal reacts, and generates with Ca2+For bridge, the friendship formed with the macromolecular system that ionic bond is connected
The reticular structure knitted not only enhances the interface cohesion of polymer phase and cement phase, enhances the density of waterproof material.
In the hydration process of cement, Ca (OH)2Reach saturation in liquid phase within the extremely short time as hydrated product, third
Olefin(e) acid ester just with OH-, Ca2+React the macromolecular network pilotaxitic texture for generating and being combined with ionic bond, and with hydration age
Extension, degree of hydration is higher, and the amount of this reaction product is bigger.
Cement is a kind of material that expression activitiy is big, although there is 85% or more cement to be not engaged in molding coating
Aquation, functions only as filler, and 15% part of aquation plays key effect in being molded flexible material.Hydrated cementitious at salt
Especially aluminium salt generates crosslinked action with the active group in polymer emulsion, to change the shaping speed of water-repellent paint,
The performance of water resistance, weatherability, acidproof, alkaline-resisting, salt tolerant of polymer etc. is set to have great raising simultaneously.Cement itself
And the material that a kind of weatherability, water resistance are splendid, but its brittleness is big, density is bad, just utilizes flexible macromolecule water-fast
Property splendid material makes up the deficiency of cement.And both cement and polymer can mutually improve respective performance.With regard to cement
Kind for, in contrast, white cement be used as polymer cement waterproof paint can be better than Portland cement, mainly because
It is usually high alumina cement for white cement, general protosalt is more in Portland cement, and high-valency metal salt aluminium salt is the same as poly-
The crosslinked action closed between the active group in object can be stronger, more preferable to the modification of high molecular polymer.Certainly in polymer water
The content of cement determines that the dosage of cement must consider forming and hardening product nor The more the better in mud water-repellent paint
Tensile strength and fracture elongation.In addition, we are also contemplated that in polymer cement waterproof paint if cement uses to obtain mistake
It is more, can cracking be generated due to flexibility difference when being molded.

The 4th part of the present invention provides High-performance green waterproofing slurry the answering in construction waterproofing engineering
With.
The water-proof emulsion in High-performance green waterproofing slurry in the present invention has excellent stability, high property of the invention
Adhesive property between waterproof slurry and base material is good, and film tensile strength is big, and uvioresistant stability is good, and also has preferable
Impermeability and water resistance.The present inventor guesses the possible reason is the waterproofing slurry of the present invention includes that organo montmorillonite changes
Property polychloroprene latex, the polychloroprene latex be cationic latex, acrylic acid ester emulsion be anionic lotion, organo montmorillonite
Distinctive ion exchangeable and the charge itself carried can be used as compatilizer, so that water-proof emulsion is had fabulous steady
It is qualitative.Polychloroprene latex itself has excellent water proofing property, but property is unstable, and neoprene is enhanced with the compounding of organo montmorillonite
The stability of latex, and the layer structure of organo montmorillonite further enhances the water proofing property of film.
Nano-particle itself exists as filler, but the difference of inorganic material and organic emulsion system property, makes film
There are larger internal stress for inside, influence the property of film.By the modification of polystyrene, nano-particle is made to have with emulsion system
There is a preferable compatibility, and poly hydroxy ethyl acrylate is polar molecule, passes through hydroxyl thereon and nanoparticle surface
Hydroxyl reaction, polystyrene can just be grafted on nanoparticle surface, and polystyrene hydrophobicity is strong, and Polystyrene is received
The presence of rice corpuscles further enhances the water proofing property of film.Poly hydroxy ethyl acrylate is soft segment, is conducive to enhance
The tensile strength and compressive property of film.And there are a variety of polyolefin compounds in system, can induce in the presence of ultraviolet
Further crosslinking occurs, to enhance the tensile property of film.
