Description
Technical field
The present invention relates to a kind of hydrophobic modified alkalis excited inorganic polymer-coated repair materials, for surface reconditioning and the protection of construction work, be particularly useful for body of wall, hydro project, tunnel, bridge, highway, harbour, the concrete reparation in pond and protection, belong to building material field.
Background technology
Soil polywater mud is the novel alkali-activated carbonatite gelling material of a class that eighties of last century is developed by French JDavidovits the end of the seventies, it refers to that by chainotte (metakaolin is main), industrial residue etc. be main raw material, is formed under the effect of alkali-activator.Sial oxygen compound in the mineral of the poly-cement raw material of soil experienced by one and defines the structure of some natural mineral in the similar earth's crust by the process of depolymerization to repolymerization, is the novel gelled material of excellent durability.Many mineral or mineral compound can have pozzolanic activity or latent hydraulicity after high-temperature calcination, such as kaolin has good activity after the calcining of 500-900 degree, slag, slag, flyash etc. be all through high temperature after product, also have good activity, the wollastonite, ettringite, Wingdale, calcite etc. of calcining are all good active materials.Along with going deep into of research, the kind of exciting agent has been not limited to conventional alkali, but has occurred the multiple materials such as basic carbonate, silicate, vitriol, and thus compound activator has appearred in mode of excitation.Above-mentioned materials is generically and collectively referred to as Chemical-activated Materials, also inorganic polymer material is, from overall performance, alkali-activated carbonatite and the gelling material based on alkali-activated carbonatite will significantly better than non-alkali-activated material, therefore, on ordinary meaning, alkali-activated carbonatite and the gelling material based on alkali-activated carbonatite are referred to as alkalis excited inorganic polymer materials.The remarkable advantage of alkalis excited inorganic polymer materials is very firm and durable with the bonding of concrete substrate, therefore can not produce the problems such as disengaging, peeling, warpage.Alkalis excited inorganic polymer materials may be used for coating material also can be used as concrete defect repair materials.
The construction works such as current bridge, tunnels and ports adopt clear-water concrete in a large number; all can there is the problem of aging such as carbonization, steel bar corrosion over time, become in these engineerings; address these problems and must take sfgd., guard method comparatively conventional at present has: brush various coating and sand-cement slurry is whitewashed.The greatest drawback of sand-cement slurry is firm not with concrete bonding, and easily come off, therefore this method generally uses in not too important occasion, fewer and feweri in important occasion.
Coating can be divided into interior wall coating, exterior coating, Clear paint etc., the greatest problem of above-mentioned materials is poor durability, for general building, this paint-based instinct meets the demands, but be difficult to satisfy the demand for important engineering, what the Yangpu Bridge bridge tower in such as Shanghai City adopted is exterior coating, therefore bridge tower must whitewash once every about 10 years, very labor life is lost money, more engineering is also had to be do not protect concrete, such as some viaducts, motorway, the bridge of railway engineering, all directly adopt clear-water concrete, outside is protective cover not.
Shanghai City the earliest be loose Pu bridge across Huangpu River Bridge; this bridge has employed 40 years; there is concrete aging phenomenon till now; steel bar corrosion; just planning at present to remove; therefore important concrete structure is carried out protecting and reparation is very important; concrete that is aging, that damage can adopt alkalis excited inorganic polymer materials to carry out repairing and protecting; estimate that loose Pu bridge can be increased the service life more than 100 years by the reparation of hydrophobic modified alkalis excited inorganic polymer-coated repair materials and protection, therefore there is very important economic worth.
Although alkalis excited inorganic polymkeric substance has many outstanding performances, but the practical application of alkalis excited inorganic polymer materials is very rare, even if some technology applied for a patent, in Practical Project, almost not realize application completely yet, this is because alkalis excited inorganic polymer materials itself also also exists some defects, and high-performance cement technology is more and more ripe, in most of occasion, alkalis excited inorganic polymer materials is difficult to alternative cement, even so, if can accomplish to learn from other's strong points to offset one's weaknesses, alkalis excited inorganic polymer materials still has some ample scopes for abilities.
Application number be 201010299679.0 name be called that the patent of " a kind of bi-component environmental-protecting inorganic polymer coating material and preparation method thereof " is a kind of formula of typical alkalis excited inorganic polymer materials; because alkalis excited inorganic polymer materials is hydrophilic material; pore through in a large number can be produced in its process of setting; define the passage of water permeation; therefore this coating cannot the invasion and attack of block water; from test; even less than cement-based material, therefore very poor to the protected effect of body of wall.Coat inside gathers moisture several harm: one is the invasion and attack that protected structure can be subject to water, and weather resistance reduces, and two is can produce freeze-thaw damage winter, this is because water volumetric expansion when icing, breakdown of coating is fallen.Improving its protective capability is necessary to carry out hydrophobic modified, to block the passage of capillary percolation.
Summary of the invention
Alkalis excited inorganic polymer materials is hydrophilic material, and can produce a large amount of through pores in its polymerization process, this is very unfavorable to the infiltration of anti-sealing.In general, the surface energy of hydrophobic material is very low, has unique advantage for waterproof, if with the material of hydrophobic nature to the modification of alkalis excited inorganic polymer materials, can block the approach of capillary percolation, thus significantly promote barrier propterty.Experiment shows, moisture permanent sequestration can be made in the side of coating through hydrophobic modified alkalis excited inorganic polymer materials, until moisture is air-dry, and in 1.5 seconds, just can see infiltration water at coating backside without hydrophobic modified alkalis excited inorganic polymer materials, contrast fairly obvious.
Can be used for that hydrophobic modified hydrophober is carried out to inorganic polymer material and have two classes: the material of a class to be self be hydrophobic nature, be dispersed in after among inorganic polymer material, whole coating material system is made also to have hydrophobic nature, another kind of be self might not be hydrophobic, but create series of chemical after being added in coating material system, its reaction product has hydrophobic nature, regardless of which kind of material, achieve hydrophobic modified equally, the barrier propterty of coating material is improved, the degree of hydrophobic then regulates according to the hydrophobic modified material usage mixed.
The present invention is to improve prior art, the advantage of combined alkali excited inorganic polymer materials and hydrophober, there is provided a kind of and be connected with matrix reliably, hydrophobic modified alkalis excited inorganic polymer-coated repair materials that water resistance is good, another object of the present invention is to provide a kind of concrete defect repair materials.
