The present invention discloses a kind of ultraviolet light polymerization engineering materials, it is characterized in that comprising following component: water-soluble polymer UV-cured resin 1 ~ 5 part, 10 ~ 15 parts, flyash, cement 5 ~ 10 parts, green stone or sandstone 5 ~ 10 parts, containing 40 ~ 70 parts organic, mud, with parts by weight.The present invention makes full use of the feature of water-soluble polymer UV-cured resin snap cure after UV-irradiation, and the engineering materials of preparation has the performance of high antiseepage, high cracking resistance and anti-sulphates corrosive, is suitable for hydro project material.
Description
Technical field
The present invention relates to a kind of engineering materials, be specifically related to a kind of ultraviolet light polymerization engineering materials, be mainly used in water conservancy project building field.
Background technology
By adding the gelling material such as cement, flyash, low for original intensity, that Pollution risk is high organic silt can be treated as intensity higher, the civil material substantially harmless to environment, reach turn waste into wealth, the object of changing waste into resources, there is very high economic benefit and environment protection significance.
Existing research curing sludge intensity, mostly between 100kPa ~ 6MPa, is of limited application.And it is less in the research of impervious, cracking resistance and freezing corrosion ability to engineering materials.Because the steel bar corrosion caused from ocean environment, chloride contamination, microfracture destroys, saltings vitriol can cause concrete structure to ftracture to concrete erosion, reduce work-ing life, be unfavorable for the maintenance of engineering, therefore curing sludge to be applied to hydro project field, just need the performance strengthening the aspects such as impervious, cracking resistance and freezing corrosion.
Summary of the invention
Goal of the invention: to the object of the invention is to for hydro project the high request of the engineering materials such as concrete, mortar in impervious, cracking resistance and freezing corrosion ability, provides the ultraviolet light polymerization engineering materials of a kind of high antiseepage, high cracking resistance and anti-sulphates corrosive.
Another object of the present invention is to the using method that this ultraviolet light polymerization engineering materials is provided.
Technical scheme: ultraviolet light polymerization engineering materials of the present invention, comprises following component: water-soluble polymer UV-cured resin 1 ~ 5 part, 10 ~ 15 parts, flyash, cement 5 ~ 10 parts, green stone or sandstone 5 ~ 10 parts, containing 40 ~ 70 parts organic, mud, with parts by weight.
Preferably, described water-soluble polymer UV-cured resin is one or more in waterborne polyurethane resin, water-based epoxy acrylic resin, ethene-vinyl acetate, polyacrylamide and alkyl acid resin.
Described is training of channel mud containing organic mud, and organic content is 1 ~ 5%, by weight percentage.
Described cement is quick-drying rapid hardening cement.
The using method of described ultraviolet light polymerization engineering materials is, first by flyash, cement, green stone or sandstone, containing after the mixing of organic mud use water, again water-soluble polymer UV-cured resin is slowly added, be stirred to the test specimen making the shape of needs evenly.
After resinous polymer emulsion is mixed in whipping process, due to small molecules resinous polymer uniform particles be dispersed among grout, form resinous polymer cement slurry.Polymer gel progressively film-forming while hydrated cementitious, meanwhile, the Ca (OH) in liquid phase
2also reach capacity state thereupon, at this moment the surface coverage resin polymerization composition granule of hydrated cementitious composition granule.Proceeding along with hydrated reaction of cement, the moisture in modified cement mortar is constantly used, and the hydrated product of cement gets more and more, and water mudrock structure is formed gradually, and resin polymerization composition granule is dispersed in the space of sand-cement slurry gradually.Due to the continuous loss of moisture, the moisture in pore is fewer and feweri, Behavior of Hardened Cement Paste together with resinous polymer granular cementation, on hydrolysis product of cement surface close by polymeric membrane, and sealer coat is just in hydrolysis product of cement and surface of aggregate plays cohesive action.Resin polymerization composition granule has improvement result to the space in sand-cement slurry.Along with constantly carrying out of hydrated cementitious, flocculation resin polymerization composition granule together is progressively absorbed along with moisture wherein and is volatilized, the three-dimensional net structure that final formation runs through mutually, and then the internal structure improving Behavior of Hardened Cement Paste.Due to the film-forming principle of resinous polymer in sand-cement slurry, adhesive property and the penetrating quality of mortar are improved.
Water soluble resin has soluble in water, easily disperses, easily and the advantage such as sand-cement slurry stirring.Flyash, cement and containing after adding water-soluble polymer UV-cured resin in organic sludge mixture, the physically encapsulation effect produced and the chemical action occurred between polar group and hydrolysis product of cement, carrying out and the Early-age behavior of hydrated cementitious can be affected, and water-soluble ultraviolet light curing resin is after uviolizing, energy fast setting, and do not ftracture, do not shrink, weather resistance is good, is excellent engineering materials.
The present invention compared with prior art, its beneficial effect is: pass into and add water-soluble polymer UV-cured resin, the pressure-proof and snap-resistent of the conventional material curing sludge engineering materialss such as cement can be increased, the more important thing is and performances such as increasing impervious, cracking resistance and freezing corrosion make this project material can be advantageously applied to hydro project field.
