Abstract

The invention discloses the preparation and application of epoxy potting adhesive for water treatment membrane components with low hardness and high elasticity. The epoxy potting glue includes A component and B component, and the A component includes 30-70 parts of epoxy resin; 5-20 parts of reactive diluent; 10-20 parts of toughening agent; 5-30 parts of filler; 0.1 to 3 parts of coupling agent; B component includes 20 to 50 parts of polyetheramine; 40 to 70 parts of alicyclic amine; 2 to 15 parts of curing accelerator; the weight ratio of the A component and the B component is 100 :10~100:50. The present invention realizes the characteristics of low hardness, high elasticity and stable hardness of the epoxy potting glue through the "trinity" toughening modification method of flexible toughening agent, active toughening diluent and flexible curing agent ; and while the epoxy potting glue has excellent bonding performance, it has low initial viscosity, fast mold filling speed, and easy operation, which can greatly improve the sealing efficiency of the membrane module, and is suitable for the packaging of water treatment membrane modules and the flexibility of electronic devices. Packaging and other fields.

Description

technical field

[0001] The invention relates to an adhesive, in particular to the preparation and application of a low-hardness and high-elasticity epoxy potting glue for water treatment membrane components. Background technique

[0002] With the development of society and economy, human beings consume more and more water resources, and problems such as shortage of fresh water resources and water pollution are becoming more and more serious. Membrane water treatment technology is an energy-saving and high-efficiency purification technology. Its process uses a selectively permeable membrane as the separation medium. When there are driving forces such as pressure and concentration differences on both sides of the membrane, its uniform pore size is used to intercept water. Particles, bacteria and other substances to achieve the purpose of separation and purification. Hollow fiber membrane is a kind of separation membrane with high surface area, fibrous shape and self-supportin...
