Abstract
The invention relates to the technical field of plugging agents, in particular to a plugging agent special for a building roof crack. The plugging agent comprises, by weight, the raw materials of 30-50 parts of silicone rubber, 20-30 parts of calcium sulphoaluminate, 10-20 parts of sepiolite, 5-10 parts of Teflon, 8-16 parts of sodium tripolyphosphate, 8-18 parts of titanium dioxide, 5-10 parts of wollastonite and 10-20 parts of curing agent. The plugging agent special for the building roof crack can both be used on the upstream face and the downstream face, impermeability pressure is high, cementation power is high, anti-cracking effect is good, the plugging agent and a base body are combined into a whole, ultraviolet resistance and aging resistance are achieved, waterproof performance is obvious, and waterproof performance, permeability resistance and quick plugging are achieved.
Description
Technical field
The present invention relates to plugging agent technical field, particularly the special plugging agent in building roof crack.
Background technology
The quality of waterproofing quality is directly connected to the work-ing life of buildings and structures and living and working in peace and contentment of the people, in recent years, the incidence of the roof waterproof seepage of China's building is high, part building is when non-delivery use, just there occurs seepage, the percolation ratio that current roofing occurs in the waterproof guarantee time limit has exceeded more than 50%.
For the seepage that building construction occurs, the outer anti-partial failure of normally building, waterproof layer is caused to occur seepage, and infiltration just must can enter building interior by concrete defect, infiltration is caused in crack as tiny in inside concrete, during concrete construction, owing to vibrating unreal, impermeability that is that occur is poor position infiltration is very general free and unfettered, the waterproof layer design major part of domestic building designers' routine adopts coiled material class water-proof material, wherein in the majority with SBS waterproof roll, for this kind of water-proof material, because the mode adopting point to be stained with is constructed, easily occur wearing water phenomenon, find water-proof material ooze vanish a little more difficult.In order to administer infiltration rapidly and effectively, repairing fast building interior concrete defect position, is the good method solving leakage of building.The comparatively normal method adopted has chemical grouting leak stopping method or carries out the stifled method vanished fast with plugging agent at present.
Chemical grouting leakage stopping technology is the slurries made by pharmaceutical chemicals, and being circulated into force feed equipment needs distress in concrete position to be processed, to reach the object of reinforcement and strengthening or impervious leakage-stopping.Injection material has numerous species, as ring Gas class, unsaturated polyester class, propylene amine, polyurethanes etc., use polyurethane grouting material to carry out leak stopping at present for creepage concrete more, the major advantage of this technology: for comparatively obvious crack, be greater than the infiltration crack of 0.1mm, injecting urethane grouting material can sealing comparatively rapidly, reaches the requirement of administering and oozing culvert.But this technology also has comparatively significantly shortcoming: (1) and that cause concrete surface unreal for concrete vibrating oozes and vanish, and the mode of slip casting is helpless, because cannot find obvious crack in filling process, therefore cannot form the passage of grouting; (2) crack after grouting, if due to factors such as settlement of foundation, may cause crack to continue to expand, just likely cause second time seepage.For this leakage problems, be badly in need of research and development a kind of safety durable plugging agent, could by infiltration thoroughly refuse outside building structure.
Summary of the invention
Technical problem to be solved by this invention is to provide the special plugging agent in building roof crack, its back water face all can use, impermeability pressure is high, viscosifying power is strong, effect of prestressed is good, entirety is combined into matrix, occur that the possibility of secondary seepage is low, uvioresistant, anti-aging, water tolerance are given prominence to, waterproof, impervious, fast blockage.
For achieving the above object, the present invention adopts following technical scheme:
The special plugging agent in building roof crack, be made up of the raw material of following weight part:
Silicon rubber of the present invention, calcium sulphoaluminate and sepiolite are as material of main part, water-swelling also absorption is put up a bridge crosslinked, form three-dimensional grid structure, solid phase particles coacervation in spatial grid structure is deposited as enrich body, significantly improves waterproofing and leakage-stopping efficiency, in addition, its tool rigidity and flexibility, can play distortion and the effect of filling, applicable temperature range is wide simultaneously, between-90 DEG C ~ 170 DEG C, there is good temperature resistance, resistance to compression, anti-aging, anti-oxidant and anti-ultraviolet performance.Wherein sepiolite wide material sources, price is lower, can reduce costs.
Solidifying agent of the present invention is 10 ~ 20 parts of lithium chlorides, 5 ~ 10 parts of talcum powder and 5 ~ 10 parts of bentonitic mixtures.Solidifying agent regulates the time of plugging agent solidification, improves the intensity of patching materials.Add the solidifying agent after talcum powder, also play the effect of filler, enter into hole, improve the compactness of cured body, improve intensity and the water-repellancy of plugging agent.
Talcous particle diameter of the present invention is 0.012 ~ 0.082mm.
The particle diameter of tetrafluoroethylene of the present invention is 0.02 ~ 0.08mm.By adding tetrafluoroethylene, making body material be dispersed in gel, playing the effect of skeletal support, improve the strength and stability of plugging agent, tetrafluoroethylene also has oilness, improves mobility and deformability, is convenient to pumping.
Titanium dioxide of the present invention can uvioresistant, and plugging agent hole filled by wollastonite, improves compactness, improves plugging agent intensity and water-repellancy.
Whole raw material of the present invention is pulvis.
Beneficial effect of the present invention is:
1, back water face all can use, and impermeability pressure is high, viscosifying power is strong, and effect of prestressed is good.
2, water can be with to construct, protection against the tide, waterproof, impervious, fast blockage.
3, be combined into entirety with matrix, uvioresistant, anti-aging, water tolerance are given prominence to.
4, there is good deformability and adaptivity, occur that the possibility of secondary seepage is low, the demand of long-acting water-proof can be met.
5, nontoxic, harmless, pollution-free, environmental protection.
