Abstract:
Adhesives have a lot of applications in everyday life from aeronautics to aerospace
industries due to its excellent properties. Adhesives are available into different forms liquid
or semi liquid form with some other forms like glues, gums, cements, and bonding agent.
Adhesives provide more good stress distribution and flexibility in comparison of riveting
and welding. Adhesives are classified into major types i.e. Structural and Non-Structural
adhesives. Structural Adhesives are epoxides, acrylics, and polyurethane. Non-Structural
adhesives are Pressure sensitive adhesives and bio adhesives. Structural adhesives are
preferable over non-structural adhesives because structural adhesives become integral part
of material and have more strength. Epoxies are thermosetting materials. They are mostly
used due to its good mechanical properties, corrosion, temperature, and environment
resistant. Bisphenol A di glycidyl ether in epoxies is mostly popular among epoxies. Epoxy
adhesive has been prepared and characterized for rubber metal binding applications. Boric
acid, Bisphenol A di glycidyl ether and 3-trimethoyxsilylpropyl chloride was added into a
beaker and stir for 15 minutes at 80C.Then, PVA was added into stirred material and heated
for two hours at 80C.Epoxy adhesives was synthesized for application rubber metal
binding. To increase the strength, metal surface was treated by etching with sulfuric acid
or hydrochloric acid. NBR was soften with aid of toluene to increase the adhesion. Rubber
was bonded to metal with help of epoxy adhesives. Epoxy adhesives was characterized by
FTIR, TGA, DSC and SEM.The rubber metal bonded part was characterized by shear
strength. FTIR has showed siloxane and borate ester bond according literature review. The
GPC has showed mass distribution because the presence of vinyl capping agent. The shear
strength has showed strength has increased up to 1.7 MPa. Development of sustainable and
eco-friendly adhesives are future goals.
