Abstract
The invention relates to an epoxy asphalt deck crack repairing agent capable of being cured at normal temperature, which comprises mixture A and B, wherein the mixture A contains the following components in parts by weight: 30-40 parts of 618 bisphenol A epoxy resin, 2-6 parts of CYH-277 reactive epoxy toughener and 3-7 parts of epoxy active diluent; and the mixture B contains the following components in parts by weight: 90-100 parts of 203 modified amine hardener, 1-2 parts of DMP-30 curing accelerator and 1-2 parts of KH-550 organic siloxane coupling agent. After being respectively prepared, the mixtures A and B are respectively stirred and mixed; and after the mixture (1) and the mixture (2) which are uniformly stirred are mixed together in the weight ratio of 3:1, the mixture (1) and the mixture (2) are stirred and mixed to obtain the repairing agent. Because the repairing agent contains the bisphenol A epoxy resin, the repairing agent has super-strong bonding capability and stable performance in the variation range of deck temperature; the repairing agent has good high-temperature flow resistance, compact structure, water tightness, certain deformation resistance and good chemical corrosion resistance; and the comprehensive performance of the repairing agent is obviously better than that of the traditional asphalt crack pouring material.
Description
Technical field
The present invention relates to the maintenance repair materials of bituminous epoxy bridge deck pavement, relate in particular to a kind of normal-temperature curing epoxy asphalt bridge floor crack repairing agent.
Background technology
Along with the fast development of motorway and bridge technology, increasing bridge adopts epoxy bitumen material as bridge deck pavement, has increased substantially the quality and the work-ing life of deck paving.
The layer but more domestic asphalt bridge floors are mated formation can ftracture because of the increase that the volume of traffic and axle carry.And epoxy bitumen material has the bigger characteristics of rigidity, in case cracking occurs, perforation that will be from top to bottom forms the crack.Because these fissured existence, water layer or waterproof effect are not bad if deck paving is set up defences, and the water of surface layer or ice-removal salt solution then can infiltrate from the crack, thereby cause the damage of decking, even corrosion reinforcing bar, finally cause the structural damage of bridge.Epoxy bitumen material hardness is very big, can't resemble maintenances such as carrying out milling the plain asphalt road surface and handle, and can only adopt the material of good penetrability to carry out the cementation of fissures.But the binding ratio between gap-grouting materials such as common heated bitumen and bituminous epoxy a little less than, often in the time about 1 year, will ftracture again.
Summary of the invention
Main purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, for the maintenance of epoxy asphalt pavement layer provides a kind of normal-temperature curing epoxy asphalt bridge floor crack repairing agent, to satisfy the request for utilization of bituminous epoxy bridge floor cracking maintenance.
Above-mentioned purpose is realized by following technical scheme:
Comprise two kinds of mixtures of first, second; Said first kind mixture comprises the component of following parts by weight: 30～40 parts of 618 bisphenol A epoxide resins, 2～6 parts of CYH-277 response type epoxy toughening agent, 3～7 parts of epoxy active diluents; Said second kind mixture comprises the component of following parts by weight: 90～100 parts of 203 modified amine curing agents, 1～2 part of DMP-30 curing catalyst; 1～2 part of KH-550 organo-siloxane coupling agent after first kind mixture and second kind mixture are prepared respectively, mixes respectively; With two kinds of mixtures of first, the second that stirs by the preparation of 3: 1 weight ratio after; Mix, make said renovation agent, mixing back proportion is 1.05～1.1g/cm
3
Crack repairing agent of the present invention is owing to contain the bisphenol A epoxide resin composition; Make it have superpower viscosifying power, and stable performance in the bridge deck temperature variation range, the good high-temperature resistance to flow possessed; Compact structure is waterproof; Certain non-deformability is arranged, also have good resistance to chemical corrosion, its over-all properties obviously is superior to traditional pitch gap-grouting material.
Embodiment
Below in conjunction with embodiment the present invention and advantage thereof are further specified.
The related mixing of following embodiment is all carried out through whipping device, generally uses low speed gear, reaches to mix to get final product.
Embodiment 1
