InactiveCN103275625AFast curingEffective bondingNon-macromolecular adhesive additivesMacromolecular adhesive additivesPolymer sciencePlasticizer
The invention discloses an adhesive for quickly mutually sticking vulcanized silicone rubbers and a preparation method of the adhesive. The preparation method of the adhesive comprises the following steps of: adding alpha- ethyl cyanoacrylate, a thickener, a stabilizer, a plasticizer and a sticking promoter to a water-free oxygen-free reactor; mixing for 0.5 hour-4 hours at 40 DEG C-80 DEG C under the protection of a dry nitrogen gas atmosphere; cooling to room temperature and finally introducing dry sulfur dioxide gas and stirring for 0.5 hour-2 hours. On one hand, the adhesive provided by the invention can overcome the defect that the common rapid curing adhesive has poor adhesion with the vulcanized silicone rubber; on the other hand, the adhesive can overcome the defects that the room-temperature vulcanized silicone rubber (RTV) is long in curing period and low in production efficiency when used for adhering the vulcanized silicone rubber. The adhesive disclosed by the invention has the advantages of high curing speed, short curing period and high adhering strength for the vulcanized silicone rubber, and can be used for realizing in-situ forming of vulcanized silicone rubber products.
