Abstract
A concrete repairing material is prepared from UP as cementing material, filler, plasticizer, trigger, promoter and coupling agent. It can be used for building, highway, etc. Its advantages are high mechanical performance and high durability.
Description
Technical field
The invention belongs to building material technical field, being specifically related to the polymkeric substance is the concrete repair material and the using method thereof of main raw material preparation.
Background technology
Concrete is to use the most extensive, that application quantity is maximum a kind of material in the current material of construction.It can be mixed with varying strength, different performance and difform various buildings.But because the influence of the residing envrionment conditions of buildings, construction quality is not good or design improperly, tends to produce all diseases, reduces the works quality, reduction of service life.Therefore, concrete structure just must renovate or repair after damaging to a certain degree, and the quality of concrete repair material and construction quality thereof also directly has influence on the work-ing life of concrete works.
The patching material of concrete structure is mainly inorganic and organic two classes.Mineral-type mainly contains short-term strength cement, super-early strength cement, accelerated cement and mortar, concrete etc.Organic class mainly contains synthetic resins and mortar thereof, concrete.Also have by the formulated polymer cement mortar of this two classes material, polymer cement concrete etc. in addition.Cement class material mainly is suitable for big area and repairs because of it is cheap, wherein early strong, super-early strength cement can be used for quick repairing, but the fragility of this class patching material is big, splitting resistance is poor, some durability index are all relatively poor as impermeability, frost resistance, wear resistance etc., especially the cohesive force between this class patching material and the old concrete is very low, after it is stressed, be easy to come off, therefore, be not suitable for adopting this type of material for the higher occasion of life requirement.In some life requirements higher concrete repair or structural strengthening, adopt more still resin slurry (PM) or resin concrete (PC) at present, this type of material can not only recover original intensity of concrete structure and integrity, and can improve wear resistance and impermeability, frost resistance and the shock-resistance etc. of concrete structure, generally this type of material is also higher with the cohesive strength of the old concrete of being repaired.Resins, epoxy, urethane resin, furane resin patching material are typically arranged, wherein best with the performance of Resins, epoxy (EP).Therefore but the disadvantage of this class patching material is that price is more expensive, is unwell to big area and uses, and comparatively speaking, the price of unsaturated polyester resin (UP) is more cheap, and its mechanical property and endurance quality are all better.The external existing depleted plastic beverage bottle, main component of utilizing is polyethylene terephthalate (PET) makes UP after processing report.Therefore making unsaturated polyester mortar (UPM) with UP has a good application prospect as the concrete repair material.
Summary of the invention
The purpose of this invention is to provide good concrete repair material of a kind of mechanical property and endurance quality and preparation method thereof.
The concrete repair material that the present invention proposes, be to be gelling material with general unsaturated polyester (UP), add suitable filler, softening agent, initiator, promotor, coupling agent etc. and form unsaturated polyester mortar (UPM), the proportioning that its component is pressed mass fraction is as follows:
1) unsaturated polyester resin (UP) 100
2) dibutyl phthalate (DBP) 10-50
3) the pulpous state solution 2-6 of 50% cyclohexanone peroxide
4) solution of cobalt naphthenate in vinylbenzene contains 2% cobalt metal 1-5
5) silane coupling agent 0-5
6) titanate coupling agent 0-5
7) cement 50-250
8) quartz sand 150-750
Make the UPM cured article produce bigger contraction because the polycondensation meeting takes place when solidifying UP, can control the shrinkage value of UPM by the ratio of adjusting cement components, gelling material and filler.Wherein DBP is as the softening agent of UP, in order to the plasticity that increases UPM, the contraction that reduces UPM.Cyclohexanone peroxide and cobalt naphthenate are used separately as initiator and the promotor of UP.According to the requirement and the changes of seasons of different engineerings, by adjusting the set time that initiator and promotor volume can change the UPM patching material.Can be controlled in 0.5-6 hour the set time of general UPM.Also can add an amount of silane coupling agent and titanate coupling agent, its effect mainly is to improve gelling material and fill the interface performance between the material, the intensity of raising UPM, also helps improving the adhesive property of UPM and old concrete.
The UPM concrete repair material contracts power that the present invention proposes is little, and mechanical property and superior in durability can be widely used in building, the concrete works of road, harbour, airport, railway tunnel repairs.
The invention allows for the preparation method of above-mentioned UPM, concrete steps are as follows:
Usage ratio by above-mentioned each component takes by weighing each component, earlier with UP with softening agent is mixed stirs; Add coupling agent again, stir; Add initiator then successively, promotor stirs; At last cement and quartz sand are mixed thoroughly in the back adding said mixture, can be built use after stirring.
The using method of UPM patching material is as follows:
1, cuts the loose concrete of concrete surface,, remove fragment, the dust of concrete surface, have ponding in time to remove as the surface with machinery or other material cleaning concrete surface;
2, preparation UPM patching material, initiator and accelerator level can be regulated according to field condition;
3, build the UPM patching material that has prepared;
4, the surface is floating, and natural curing gets final product.
