AI Technical Summary
Technical Problem
Existing adhesives cannot foam independently when needed and require heating to cure, which cannot meet the needs of certain industrial applications.
Method used
A two-component acrylic adhesive is developed, which consists of the first component and the second component, which are spontaneously mixed under ambient conditions, triggering chemical reactions that lead to curing and foaming.
Benefits of technology
The function of independent curing and foaming at ambient temperature is realized, the heating step is avoided, and the application flexibility and efficiency of the adhesive are improved.

Abstract
The present invention relates to an autonomously curable and foamable two-component acrylic adhesive, which spontaneously foams and cures when the two components are combined with each other, thereby forming a cured foamed acrylic adhesive. The cured foaming acrylic adhesive can be used as a structural adhesive, a sealant, a noise reduction material and the like. The cured foamed acrylic adhesive is particularly useful for structural reinforcement within cavities of structural elements such as motor vehicles, aircraft, railway vehicles or other vehicles.
