As a high-tech environment-friendly material, the inorganic anchor adhesive has characteristics of ultra high strength, high temperature resistance, antifatigue and very strong durability, can be directly welded, is suitable for operating in water environment, and can be widely used for maintaining buildings and planting a rebar and a bolt in reinforcing. The inorganic anchor adhesive has wider application range, and solves multiple bottleneck problems in anchoring industry, so that the construction operation is not limited by factors like environment any more, construction efficiency and rate are greatly improved, and the engineering cost is lowered.
Description
Technical field
The invention belongs to building structure strengthening Material Field, relate to the anchoring material that a kind of bar planting is used, specifically a kind of cement base inorganic anchoring adhesive and preparation method thereof.
Background technology
Anchoring adhesive is that in reinforcing, application is comparatively extensive in building structure, and anchoring adhesive is divided into inorganic anchoring adhesive, organic anchoring adhesive conventionally.The bonding reinforcement material of building structure that organic anchoring adhesive is made up of synthetic resins, packing material and chemical assistant.There is the features such as anchor force is strong, construct simple and direct, the cost of material is low, erosion resistance, be applicable to the reinforcement of the connection of new and old buildings thing, reinforcement of building, Equipment Foundations anchoring and brick masonry building structure.The organic anchoring adhesive of main employing in the market, as like sharp obtaining, intelligent fish, Simpson's brand etc.Inorganic anchoring adhesive is made up of inorganic mineral micro mist and inorganic solidification agent aqueous solution two-pack.It is to utilize colloid chemistry, under the effect of the inorganic solidification agent aqueous solution, different active particles produce high efficiency ion-exchange, generate new inorganic bar planting adhesive material, be widely used in concrete, Steel Concrete, geotechnical engineering, house, bridge, tunnel, tunnel, mine, dam, oil well, ocean harbour, ocean platform etc.At present, the application of inorganic anchoring adhesive is not also widelyd popularize, and reason is that people lack understanding and the research to inorganic inserted bar glue material.
Make a concrete analysis of the difference of inorganic anchoring adhesive and organic anchoring adhesive below:
Stressed aspect: single from individual anchor force intensity, organic anchoring adhesive and inorganic anchoring adhesive are substantially suitable to Ribbed Bar bond stress, stressed from system, inorganic anchoring adhesive is better than organic anchoring adhesive, because inorganic anchoring adhesive and former modulus of elasticity of concrete and thermal expansivity are basically identical, the stressed cooperative transformation of system entirety before and after effectively having ensured to reinforce.
Weather resistance aspect: inorganic anchoring adhesive is better than organic anchoring adhesive.Testing circumstance: seawater, freeze-thaw cycle, thermal ageing, hydrothermal aging, 100 DEG C of high temperature.Inorganic anchoring adhesive is strength retention ratio >=100% under each testing circumstance condition, and organic anchoring adhesive strength retention ratio is between 15%～90%.
Practicality aspect: inorganic anchoring adhesive adds water and stirs and can use, construction effect, far above organic anchoring adhesive, has been avoided organic anchoring adhesive because of high-temperature stability and can not have been realized the defective workmanship that welding comes after first glue.
Economy aspect: inorganic anchoring adhesive asepsis environment-protecting, cheap, meet national economic development direction.
Concrete structure after reinforcing is for a long time in the severe environment in humidity or alternation of wetting and drying, and concrete structure reinforcement not only considers to reinforce security and the weather resistance of rear system, also should comply with society's developing direction substantially.In rear-anchorage inserted bar investigation of materials, should form by scientific and reasonable design inserted bar glue material, after novel inorganic anchoring adhesive, anchoring material arises at the historic moment.
Summary of the invention
