Abstract
The invention discloses crack repair glue. The crack repair glue comprises a component A and a component B, wherein the component A comprises bisphenol A epoxy resin 618 and a polyester, and the component B comprises a modified aliphatic amine curing agent 593 and fumed silica. The bisphenol A epoxy resin 618 accounts for 20% by mass, the polyester accounts for 12% by mass, the modified aliphatic amine curing agent 593 accounts for 20% by mass, and the fused silica accounts for 3% by mass. The component A further comprises 2% by mass of an epoxy accelerator DMP-30. The component B further comprises 43% by mass of cement. The crack repair glue disclosed by the invention can resist shrinkage stress in a curing process of colloids and is further stable and durable, the fracture toughness of a structural glue hardened body is improved by nearly ten times in comparison with a system without adding a Qishi toughening agent and is also improved by above several times in comparison with a colloid system adopting polysulfide rubber, the mechanical strength and volume stability of the hardened body can be greatly increased, and the crack repair glue further has the advantages of good compatibility with concrete, no toxicity and no odor (environmental friendliness), simple, convenient and reliable construction, large construction and using temperature range (good heat resistance), good corrosion resistance and low cost.
Description
Technical field
The present invention relates to construction structure glue field, particularly relate to a kind of crack repairing glue.
Background technology
Structural strengthening carries out reinforcing to the buildingss such as building structure, road, bridge, reservoir dam, culvert or structures at present, extends the most effective means in its work-ing life.Making a general survey of this series products, is all with the modified epoxy of certain viscosity for host, and the amine modified firming agent that can solidify at ambient temperature is assistant agent, is aided with the auxiliary agent compositions such as appropriate reactive thinner, toughner, coupling agent and filler.The intensity of this construction structure glue has reached a higher level, but along with the development of science and technology, new modified epoxy resin, novel solidifying agent, the toughner etc. with property constantly occur, market demands over-all properties is higher, application is more simple and convenient, the new builing structure glue of cheaper.
Summary of the invention
In order to provide a kind of novel construction structure glue, the invention provides a kind of crack repairing glue, it is characterized in that comprising first component and component B, described first component comprises bisphenol A epoxide resin 618 and polyester, and described component B comprises modified fatty amine curing agent 593 and Fumed silica.
Described bisphenol A epoxide resin 618:20%, polyester: 12%, modified fatty amine curing agent 593:20%, Fumed silica: 3%, all by percentage to the quality.
Described first component also comprises epoxy altax P-30:2%, all by percentage to the quality.
Described component B also comprises cement: 43%, all by percentage to the quality.
The present invention can resist string stress in colloid solidification process, and it is stable lasting, the fracture toughness property of structure glue hardenite is than not Jia Qishi toughner system improve nearly ten times, also more than several times are improved than adopting the colloidal dispersion of thiorubber, greatly can increase physical strength and the volume stability of hardenite, reliable with concrete affinity good, nonpoisonous and tasteless (environmental protection), easy construction, construct and use temperature scope (resistance toheat is good), corrosion resistance and good, with low cost greatly.
