“…This enhancement in viscoelastic properties might be attributed to the rigid structural stability of the acrylic polymer matrix by UV crosslinking. 6,7,14 It was also interesting to note that higher value of G' and lower value of tanδ at 25 o C was obtained in the case of PSAs with MMT clays as can be seen in Table 4. The difference of G' and tanδ value between PSAs and nanocomposite PSAs was clearly observed at 0.3 wt% of crosslinking agent added.…”

“…3,4,6 To enhance the mechanical properties and thermal stability, multi-functional monomers has been used such as butandiol diacrylate (BDDA), hexandiol diacrylate (HDDA) and diethylene glycol diacrylate (DEGDA). 7 Usually a high degree of crosslinking lowers the peel and tack, but not always.…”

“…2 Acrylic acid is usually copolymerized with 50~90% major polymer because of carboxylic group in its structure is useful for crosslinking and modifying cohesive strength. 2,6 As PSAs need to be able to wet the surface of a substrate and possess a low T g component to enable a tacky film to be obtained, they are usually prone to fail cohesively. This can be prevented in photo-initiated systems by incorporating a small amount of crosslinking agents.…”

UV-cured acrylic copolymer pressure sensitive adhesive (PSA) having different amounts of crosslinking agents were prepared and adhesion properties were investigated. 0.01 wt% of MMT clay was dispersed in 2-ethylhexyl acrylate (2-EHA)/acrylic acid (AA) monomer mixture containing 0, 0.05, 0.1 and 0.3 wt% 1,6-hexandiol diacrylate (HDDA) for crosslinking. It was investigated that the curing behavior and surface chemistry of PSAs were merely affected by the presence of MMT clays. On the other hand, adhesive properties were influenced by the MMT addition; a cohesive failure was restrained due to improved molecular elasticity even in uncrosslinked acrylic PSAs. However, it was also appeared that combination of 0.3 wt% crosslinking agent and MMT loading might result in the damage of adhesion properties of PSAs possibly due to the lack of chain flexibility. In our studies, it is suggested that the 2-EHA/AA PSAs incorporating 0.01 wt% of MMT and crosslinked with 0.05 wt% of HDDA exhibited the balanced adhesion properties without severe cohesive failure during strip.

“…The results of metallographic microscope show that the silicone rubber and epoxy resin in the well bonding samples are formed as a whole through chemical reaction. The bonding force between the two materials is mainly formed by a variety of intermolecular forces, among which the hydrogen bond with the interaction energy of more than 40 kJ/mol is considered to be the main contributor to the interfacial bonding force according to [27]. Hydrogen bond is formed by epoxy ring in epoxy resin as acceptor and hydroxyl group of silicone rubber as donor.…”

Testing Method for Composite Insulators Interface Based on Nonlinear Ultrasonic

The interface is the weakness of composite insulators. As the interface bonding fails, the uniform distribution of electric field will be affected, which accelerates the aging of composite insulators and affects the safe operation of transmission lines. Because of the stress between the sheath and the rod, the air gap at the interface is generally less than 10 ţm and there is extrusion contact in some areas. Therefore, conventional nondestructive testing technology based on refraction and reflection principle cannot effectively identify the faulty insulators in the initial stage of bonding failure. Based on the constitutive model of the interface of composite insulators, the friction force of the interface after bonding failure introduces more nonlinearity in mechanical properties than hydrogen bond under well bonding condition. The numerical results show that under the influence of the nonlinear constitutive relation, the higher harmonic components in the spectrum will increase significantly. The experimental results of plate and insulator samples confirm the validity of numerical calculation. Based on the normalized nonlinearity coefficient, the interface state of composite insulators at the initial stage of bonding failure can be effectively identified.
