Abstract

The invention provides a water-based epoxy adhesive and application thereof, the adhesive comprises: an epoxy component and a curing component; the epoxy component includes a water-based epoxy resin emulsion; the curing component includes an amine curing agent and a water-based polyurethane emulsion, the water-based polyurethane emulsion is 10%-40% of the total mass of the cured components, and the solid content of the water-based polyurethane emulsion is 25%-50%. The present invention adopts the epoxy system in the form of water-based epoxy resin emulsion, which has good bonding performance, excellent hardness and rigidity. Moreover, the present invention mainly toughens the epoxy resin matrix by introducing a certain amount of water-based polyurethane emulsion components. Applying the adhesive described in the present invention to bond high-performance fiber bullet-proof panels can enable the bullet-proof panels to obtain excellent impact resistance and reduce the depth of depression after bullet impact on the premise of ensuring sufficient bonding strength, hardness and rigidity of the adhesive layer. Improved bulletproof effect.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to a water-based epoxy adhesive and its application in bonding high-performance fiber bulletproof boards. Background technique [0002] Although the development of ceramic bulletproof plates is rapid, the brittle defects of its materials have not been well resolved. Therefore, the role of high-performance fiber bulletproof panels is irreplaceable. The bulletproof mechanism of high-performance fibers is to absorb a large amount of energy and prevent bullets from penetrating through energy transfer. At present, the most commonly used fiber composite sheet with the best bulletproof effect is ultra-high molecular weight polyethylene fiber bulletproof sheet, which is a flexible material. [0003] Existing high-performance fiber bulletproof panels such as ultra-high molecular weight polyethylene fiber bulletproof panels, the preparation process usually includes: unidirectional sprayin...
