Study and Application of Silicone Nano Hybrid Modified Epoxy Adhesive

Nano silicone sol was synthesized by sol-gel method and the shape and size of nano particle was characterized by TEM and IR respectively.The nano sphere particle size was 30~70nm.The modified epoxy adhesive was prepared by adding active diluent furfural,acetone and silicone.The initial viscosity,permeability,mechanical strength,elastic modulus,adhesion,surface hydrophobicity and anti-corrosion of the adhesive were studied.The results showed that the epoxy resin content,silica sol and silane coupling agent had significant effects on the properties of the modified adhesive.The modified epoxy adhesive had a low initial viscosity of 1.1 mPa·s,a high permeability,a high compressive strength of 40.8~81.5 MPa,an elastic modulus of 1.3~2.1 ×103MPa,a shear strength of 5.1~11.9 MPa,and its waterproof and antiseep ability,anti-corrosion and weather resistance are good.It could be used in many fields such as grouting,waterproof,reinforcement,industrial flooring coating and anti-corrosion coating.
