Description
Technical field
The invention belongs to the sealer technical field, be specifically related to a kind of non-drying preserving and sealing glue and preparation method thereof with drying power.
Background technology
Bridge steel structure is used early in China, but limited by national economic strength and state of the art, develops slowlyer, and along with the bridge steel structure extensive application, China also progressively becomes influential world bridge big country over past ten years.In the bridge steel structure application process, exist the corrosion failure problem of general steelwork, in order to guarantee the safety of bridge, the corrosionproof protection of bridge steel structure has become the important topic that guarantees the operation of steel structure bridge long-term safety.
Main push-towing rope is suspension bridge " a safe lifeline ", is the topmost supporting member of suspension bridge the work-ing life that has influence on suspension bridge of the seriously corroded of main push-towing rope steel wire, and is non-exchange in the usage period of whole bridge.In case main push-towing rope generation corrosion failure, consequence is hardly imaginable.The security incident that all has the main rope of suspension bridge corrosion to cause both at home and abroad, loss are very heavy.Therefore, protection main push-towing rope protect it from corrosion becomes the normal key issue of runing of suspension bridge.
Chinese invention patent ZL99119397.0 patent of invention prospectus; Disclose the means of defence of a kind of main rope of suspension bridge system and used sealer: the said non-vulcanization type rubber of this patent non-drying sealing compound has good preserving and sealing performance; The micro-moisture of invading to external world has certain iris action; And then play the purpose of protection main push-towing rope protect it from corrosion; But there is not dry adsorption to being wrapping to the inner residual moisture of main push-towing rope in the anticorrosive construction process of main push-towing rope inside, will be to burying potential safety hazard the work-ing life of main push-towing rope.
Because the main rope of suspension bridge anticorrosive construction all carries out site operation at the construction field (site).Transport the scene to carrying out the main push-towing rope anticorrosive construction from main push-towing rope, the cycle is longer, and in this process, the main push-towing rope steel wire is in the outer protection state that do not coat, and owing to the ambient weather reason, it is inner to make moisture penetration get into main push-towing rope inevitably.Before main push-towing rope carries out anticorrosive construction, the inner assurance relatively dry that is difficult to of main push-towing rope.After anticorrosive construction was accomplished, the inner residual moisture of main push-towing rope will be hidden danger of main push-towing rope corrosive.
