Abstract
The invention relates to a retarding adhesive for steel strand. The retarding adhesive provided by the invention comprises the following components of: by weight, 20-60 parts of epoxy resin, 15-30 parts of a curing agent, 2-7 parts of a modifier, 5-10 parts of a diluent and 80-150 parts of a filling material. The invention has the following beneficial effects: the diluent is used to reduce the viscosity of the adhesive and the amount of the filling material is increased so as to decrease the cost; The curing agent is used to increase the cohesive force of the adhesive during the curing process and provide a cured product with high strength and heat resistance; the adhesive has strong corrosion resistance so as to prolong the service life of the product.
Description
Technical field
The present invention relates to adhesive area, especially relate to a kind of slow setting tackiness agent that is used for steel strand.
Background technology
Slow-adhesion prestress steel strand is an emerging product in present China prestressing technique, is comprehensive do not have bonding and two kinds of characteristics of product of bonded prestress steel strand, and improvement forms.Slow-adhesion prestress steel strand comprises prestress wire, be set in the outer plastics jacket of prestress wire and be filled in plastics jacket and prestress wire between the slow setting tackiness agent.
The slow setting tackiness agent is equivalent to not have the agglutinating grease in earlier stage, has certain fluidity and good tack, guarantees that deformed bar is simple and easy to do in the cloth muscle of engineering and stretching process.Pass in time, the slow setting tackiness agent solidifies gradually.The slow setting tackiness agent has the intensity higher than concrete after completely solidified.
Summary of the invention
The present invention provides a kind of slow setting tackiness agent that is used for steel strand.
For realizing above-mentioned goal of the invention, the technical scheme that the present invention takes is following:
A kind of slow setting tackiness agent that is used for steel strand is made up of the component of following weight part: epoxy resin 20-60 part, solidifying agent 15-30 part, properties-correcting agent 2-7 part, thinner 5-10 part, filler 80-150 part.
Preferably, described solidifying agent is a polyamide resin.
Preferably, described properties-correcting agent is resol.
Preferably, described thinner epoxy propane butyl ether.
Preferably, described filler is a cement.
The effect of thinner is to reduce viscosity, improves the perviousness of resin.
Polyamide resin is corrosion-resistant, flexibility good.
The effect of properties-correcting agent is for the flexibility that improves epoxy resin, shearing resistance, bending resistance, anti-impact, raising insulating property etc.
The invention has the beneficial effects as follows: 1, thinner has reduced the viscosity of tackiness agent, has increased amount of filler, has reduced cost.2, the use of solidifying agent has increased the force of cohesion of tackiness agent in solidification process, makes the product after the curing have high intensity, has thermotolerance simultaneously.3, erosion resistance is strong, has prolonged the work-ing life of product.
Because.
Embodiment
Below in conjunction with embodiment, to details are as follows according to embodiment provided by the invention:
Embodiment 1
Be used for the slow setting tackiness agent of steel strand, composed of the following components, accurately take by weighing following component: 60 kilograms of epoxy resin, 20 kilograms of polyamide resins, 7 kilograms in resol, 10 kilograms of epoxy propane butyl ethers, 150 kilograms of cement.
Preparing method: said components is stirred at 30-40 in stirring tank ℃, after grinding, process pasty state then, promptly obtain finished product.
Tackiness agent according to the present invention's preparation is anticorrosive, and cohesive force is strong, and is high temperature resistant.
