Abstract
The invention relates to a steel strand slow setting adhesive, comprising ingredients of 30-40 parts of bisphenol A type epoxy resin, 10-30 parts of active flexibilizer polyurethane, 20-40 parts of alkali curing agent, 5-15 parts of glycidyl butyl ether and 60-90 parts of filling material. The invention has beneficial effects of stable property, adaptability to various severe environment, excellent bond property, low cost and large strength after solidification.
Description
Technical field
The present invention relates to adhesive area, especially relate to a kind of steel strand slow setting tackiness agent.
Background technology
The key of retarded adhesive prestressed technology is the development of slow setting tackiness agent, and the stability of the intensity of tackiness agent and mechanical property directly influences the adhesive property between reinforcing bar and the concrete.Prestressed concrete structure can be applied in the different environment; Particularly maritime works and the harbor work's structure erosion that can bear seawater; Prestressed Concrete Bridges can stand rain erosion; Retarded adhesive prestressed steel bar can be owing to concrete hydration heat experiences higher temperature in concrete; Can there be catabiosis in tackiness agent as a kind of organic materials, and the stability of research slow setting tackiness agent mechanical properties such as Strength Changes after salt-fog test and the accelerated deterioration under differing temps is significant for applying of retarded adhesive prestressed technology.
Summary of the invention
The present invention provides a kind of steel strand slow setting tackiness agent.
For realizing above-mentioned goal of the invention, the technical scheme that the present invention takes is following:
A kind of steel strand slow setting tackiness agent is made up of the component of following weight part: bisphenol A type epoxy resin 30-40 part, endurable active toughener urethane 10-30 part, alkaline species solidifying agent 20-40 part, epoxy propane butyl ether 5-15 part, filler 60-90 part.
Further, described alkaline species solidifying agent is the methylene-bis phenylenediamine.
Further, described filler is cement or lime carbonate.
Preferred version is made up of the component of following weight part: bisphenol A type epoxy resin 32-35 part, endurable active toughener urethane 15-20 part, alkaline species solidifying agent 25-28 part, epoxy propane butyl ether 5-9 part, filler 70-90 part.
Bisphenol A type epoxy resin is the macromolecular compound that contains epoxy group(ing), ehter bond, a plurality of hydroxyls; It is the series products that output is maximum in the epoxy resin, purposes is the widest; Its performance is also highly stable, and each item index under design temperature, humidity condition all remains unchanged.Therefore, as the main body macromolecular material, the adhesive property of slow setting tackiness agent can be guaranteed, the cost of former material can be reduced again with bisphenol A type epoxy resin.
In the slow setting tackiness agent, add mineral filler to reduce the consumption of epoxy resin, reduce cost.
The invention has the beneficial effects as follows: stable in properties, can adapt to various severe environment, adhesive property is good, and cost is low, and cured strength is big.
