Abstract

The invention relates to a high-intensity epoxy shell adhesive and a preparation method thereof. During use of the high-intensity epoxy shell adhesive, a first component and a second component are mixed according to a weight ratio of (2 to 4) to 1; the first component is prepared from the following constituent raw materials in parts by weight: 50 to 80 of epoxy resin, 5 to 25 of an activated toughening agent, 3 to 20 of a diluent and 0.5 to 5 of a deformaing agent; the second component is prepared from the following constituent raw materials in parts by weight: 30 to 80 of a toughening curingagent, 10 to 60 of a hardening curing agent and 0.3 to 1 of a coupling agent. Compared with the prior art, the high-intensity epoxy shell adhesive has the advantages of medium resistance, high-temperature resistance, low-temperature resistance, impact resistance, pressure resistance, aging resistance and the like.

Description

technical field [0001] The invention relates to a shell glue and a preparation method thereof, in particular to a high-strength epoxy shell glue and a preparation method thereof. Background technique [0002] The excellent physical, mechanical and electrical insulation properties of epoxy resin, the bonding performance with various materials, and the flexibility of its use process are not available in other thermosetting plastics. Therefore, various coatings, composite materials, pouring potting materials, adhesives, molding materials and injection molding materials prepared from epoxy resins have been widely used in various fields of the national economy. [0003] With the shortage of water resources and the rapid development of the water treatment industry, the market demand for environmentally friendly FRP composite structure water treatment containers is booming. Foreign water treatment container shells are all wound with epoxy resin / glass fiber, with excellent comprehe...
