Universal interfacial binding agent

The invention relates to a universal interfacial binding agent which comprises a component A and a component B, wherein the component A comprises the following raw materials in parts by weight: 30-50 parts of a cosolvent, 5-25 parts of en epoxy resin curing agent, 2-20 parts of a special auxiliary and 5-25 parts of filler; the component B is water soluble epoxy resin, and the weight ratio of the components A and B is (0.5-5):1. The universal interfacial binding agent provided by the invention has relatively low viscosity under room temperature, the necessary flowing property of the universal interfacial binding agent being used is guaranteed, the operable time is relatively long, and the construction pressure is greatly alleviated. The universal interfacial binding agent provided by the invention has the characteristics of being hard in coating, free of oil separation, short in drying time, green, environment-friendly and pollution-free and convenient to construct. Experiments verify that the viscosity of the universal interfacial binding agent provided by the invention at 20 DEG C is about 200cp and a good application performance for construction within 180 minutes after being mixed can be maintained.
