Abstract
- A silicone tackifier PHMS - 12 with epoxy and alkoxy functional groups for the addition - cure liquid silicone rubber( LSR) was prepared, with tetramethylcyclotetrasiloxane ( D<superscript>H</superscript><subscript>4</subscript>), octamethylcyclotetrasiloxane( D<subscript>4</subscript>), hexamethyldisiloxane (MM), vinyl trimethoxysilane and allyl glycidyl ether as the raw materials. Then the microstructure of the tackifier was characterized. the effects of the amount of PHMS -12 on the viscosity, the hardness, curing charecteristics of the liquid silicone rubber, and adhesion properties on the various substrates were investigated. Results show that when the amount of PHMS - 12 on 0. 8%, the addition - cure LSR is well bonded to polyethulene terephthalate ( PET), polyimide ( PI ), stainless steel, addition - cure LSR is well bonded to polyethylene terephthalate (PET), polyimide ( PI ), stainless steel, copper, aluminium and other substractes. The slicone rubber has the tensile strength of 7. 3 MPa, the elongation at the break of 400%, the tear strength of 30.5kN/m, Shore A hardness of 61, and the scorch time t<subscript>10</subscript> and the positive curing time t<subscript>90</subscript> is 34 s and 86 s, respectively.
