Power equipment long-term plugging special glue

The oil leakage and leakage of transformers, GIS, metal pipes and other equipment seriously restrict the safe operation of the power system. Although the commonly used plugging process can effectively block the leakage, it needs to be powered off and pressure relieved for operation, the plugging time is long, and the cost of plugging is high. Therefore, there is a need for a plugging process that can be operated without pressure. Power equipment long-term plugging glue is a two-component reactive acrylate plugging material composed of acrylate monomer, elastomer, oxidant and reducing agent. The material has the characteristics of high bonding strength, fast curing speed and oil-operable operation, and is used for structural reinforcement of quick plugging glue and long-term sealing of plugging parts.

Features
Application field
Long-term plugging glue for power equipment is a two-component reactive acrylate plugging material composed of acrylate monomer, elastomer, oxidant and reducing agent. It has the following performance characteristics:
 
1. Excellent bonding performance
 
After curing, a polymer compound having industrial strength is formed, the shear strength is not less than 20.0 MPa, and the T-type peel strength is not less than 3.0 N/mm. Efficient bonding to materials such as steel, iron, aluminum, plastics and composites.
 
2. Excellent oil surface bonding performance
 
The acrylate material can dissolve the contaminants on the surface of the substrate during the curing reaction, so that it can be well bonded to the surface of the oil layer, and the shear strength after oil bonding is not less than 20.0 MPa.
 
3. Fast curing at room temperature
 
The curing reaction of the acrylate material is a radical polymerization reaction, and an automatic acceleration phenomenon occurs during the polymerization process. Therefore, after the two-component long-term plugging glue is mixed at room temperature, the curing starts in 6 minutes and completely solidifies in 2-4 hours.
 
4. Excellent low temperature resistance
 
The long-term plugging glue still has good cross-linking degree, bonding strength and peeling strength at low temperature (-40 ℃).
