“…Hence, the shore hardness basically meets the national standard and the shore hardness of the failed O-ring gasket is slightly higher than the O-ring gasket of the same dimension. It's well known that the hardness of rubber increases with the crosslinking density [24] . Hence, the results of the shore A hardness implied that the crosslinking density is increased to some extent while used in the electric hydraulic system.…”

“…As a representative water‐soluble or water‐dispersible polymer, waterborne polyurethane dispersion (WPUD) could be a good choice as a binder polymer due to its unique structure and properties. Actually, it is easy to find literature on the basic composition and synthetic method of WPUD as well as the relationship between its structure and physical properties . Especially, ionomers, polyols and chain extenders are known to be important components in determining the physical properties of WPUDs .…”

Polyurethane (PU) composite films containing UiO-66 were prepared for the decontamination of methyl paraoxon (MPO), an organophosphate-type nerve agent simulant. Waterborne PU dispersions were synthesized by changing the type of polyol to improve the miscibility with UiO-66. Depending on the size of the polyol, the PU films had different surface free energy, flexibility and compatibility with UiO-66. UiO-66 was well dispersed in PU films when the flexibility of the films increased. The tensile strength of the UiO-66/PU composite films gradually increased from 7.5 to 11.3 MPa with increasing UiO-66 content, but the elongation decreased from 781 to 120%. The decomposition of MPO by the UiO-66/PU composite films increased with an increase of the UiO-66 content and hydrolysis time. In the case of the 21.2 wt% UiO-66/PU composite film, 48% of MPO was decomposed within 3 h. This was similar to the decomposition when using a UiO-66 slurry (52%) under the same decomposition conditions. Unlike the UiO-66 slurry, the 21.2 wt% UiO-66/PU composite film maintained a similar MPO decomposition performance after 10 repeated experiments.

ResumenSe realizó un estudio experimental para medir la fuerza adhesiva de dos láminas de composición similar unidas con adhesivo. Las láminas se fabricaron a partir de polietileno con 32% de harina Telinne monspessulana y 5,2% de polietileno maleatado. Se usaron dos tipos de adhesivos ecológicos: poliuretano en dispersión acuosa y goma caliente de etilen vinil acetato (hot melt). Los substratos o superficies a unir de cada lámina previamente fueron sometidos a abrasión mecánica. Posteriormente las superficies fueron tratadas por separado con silano vinil-tri(2-metoxi etoxi), primer acrílico y diisocianato. La resistencia a la separación de ambos substratos denominada fuerza adhesiva de la junta, fue determinada aplicando la prueba 180º T-peel adhesión. Los tratamientos químicos aumentaron la resistencia adhesiva de las juntas unidas con poliuretano, los valores más altos se obtuvieron al unir los substratos con adhesivo hot melt sin tratamiento químico. La adición de agente maleatado en el compuesto de madera plástica no mejoró la eficiencia de los tratamientos químicos.Palabras clave: madera plástica; junta adhesiva; polietileno de baja densidad; peel adhesión; primer, adhesivo. Analysis of Bonded Joints Made with (Wood Plastic Composite Sheet) / (Ecological Adhesive) / (Wood Plastic Composite Sheet) AbstractAn experimental study was performed to measure the resistance to adhesive peel strength of two sheets of similar composition bonded with adhesive. The sheets were made from polyethylene with 32% Telinne monspessulana flour and 5.2% maleated polyethylene. Two types of eco-friendly adhesives were used: aqueous dispersion polyurethane and hot melt ethylene vinyl acetate base. The substrates or surfaces to be bonded from each sheet previously were subjected to mechanical abrasion. Subsequently the surface was treated with vinyl tri (2 -methoxyethoxy) silane, acrylic and diisocyanate primers. The resistance to the separation of both substrates also named as adhesive force of the joint, was determined with the test 180º T-peel adhesión. Chemical treatments increased the peeling strength in the bonded joints with polyurethane water-based, however higher values were obtained by joining the substrates with hot melt adhesive without chemical treatment. The addition of maleate in the wood plastic composite did not improve the efficiency of chemical treatments.
