Abstract
The invention relates to an epoxy colloid for rehabilitating pipeline made of high strength multi-layered composite material. The invention is characterized in that the epoxy colloid consists of solution A and solution B with a weight ratio of 0.08 to 0.12, wherein the solution A contains modified epoxy resin (1 ), xylene(0.1-0.4), titanate coupling agent(0.01-0.1), silicon defoamer(0.01-0.05), organobentonite(0.01-0.04), dispersant of polycarbophilusp alkyl-containing ammonium(0.01-0.05), flaky mica(0.1-0.5), extra-fine talc powder(0.1-0.5) and carbon black(0.01-0.1) and the solution B contains curing agent of epoxy-mannich amide and ethanol(0.05-0.2). The colloid is provided with excellent construction performances, high bond strength and hardness, good heat-resistance and anti-osmotic, with a shear strength of over 6MPa and long-term heat-resistance of 100 DEG C. With simple production technology and easy-controlling quality, the colloid can be used in rehabilitating pipeline and on-line repairing, which can reduce the rehabilitating cost largely and prolong the service life of the pipeline, with no need of complicated big-scale production equipment.
Description
Technical field
The invention belongs to binding agent, relate in particular to a kind of renovation reinforced epoxy glue solution for repairing pipeline of multilaminar high strength composite materials that utilizes.
Background technology
All kinds of embedded metal pipelines in the industrial circle; for example burying the metallic facility overwhelming majority such as ground oil pipe, water pipe, tracheae all is operated in the medium such as the great soil of corrodibility; especially facility such as underground metallic network of pipelines of plant area; it is more various and complicated to influence the corrosive factor, if do not take necessary sfgd., all can suffer serious corrosion; thereby reduced the use properties of hardware; shorten working life, increased the maintenance cost expenditure, even caused the accident of stop work and production.Existing epoxy glue solution for repairing pipeline, adopt Resins, epoxy and solidifying agent thereof, add that solvent is formulated, its weak point is that the cohesive strength and the impermeabilisation ability of repair materials is lower, and thermotolerance is bad, for guaranteeing that repairing the back pipeline has long work-ing life, requires repair materials to have preferable performance at aspects such as cohesive strength, impermeabilisation ability and thermotolerances.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, and a kind of epoxy glue solution for repairing pipeline with superior bond strengths rendering, hardness, thermotolerance and permeability resistance is provided.
The present invention for achieving the above object, by the following technical solutions: a kind of epoxy glue solution for repairing pipeline is characterized in that: form by A liquid and B liquid, by weight the meter, wherein
