Title:
METHOD FOR BONDING RUBBER, AND ADHESIVE FOR BONDING RUBBER
Document Type and Number:
WIPO Patent Application WO/2019/025578
Kind Code:
A3
Abstract:
The invention relates to an adhesive (7) that can cure to give high-strength and permanent elasticity, for bonding at least two surfaces, at least one of which is one surface of a permanently elastic plastic (1a, 1b), the adhesive being an adhesive that cures by at least two different hardening mechanisms, the first hardening mechanism comprising a chemical reaction to form a bond that incorporates a sulphur atom and the second hardening mechanism comprising the formation of crystalline structures consisting of amorphous polymers. The invention also relates to a method for the high-strength, permanently elastic bonding of at least two surfaces, at least one of which is one surface of a permanently elastic plastic, using an adhesive of this type, the method having the steps: applying the adhesive to at least one first surface of the surfaces to be joined, ensuring conditions under which at least the first hardening mechanism of the adhesive can take place, bringing the first surface into contact with the second surface and ensuring conditions under which the second hardening mechanism of the adhesive (7) can take place.
