“…For instance impurities on mineral surfaces often dictate aggregation [15][16][17][18], while small chemical features on polymer surfaces control contact angle and wetting [19][20][21], produce membrane fouling [22,23], enhance engineering adhesion [8,24,25], and determine biomaterial effectiveness [26][27][28][29][30]. Intracellular surface heterogeneities even govern biological processes such as the initial phases of leukocyte adhesion [31,32].…”

“…Este resultado concuerda con la investigación realizada por (Gupta et al 2007), quienes elaboraron un compuesto de polietileno de alta densidad con 60% de harina de pino y le añadieron agente de acoplamiento polipropileno maleatado MAPP, la resistencia al pelado del compuesto sin MAPP es 218  16 N/m y con 2,3% de MAPP fue 177 21 N/m. En la misma investigación se evaluó la resistencia al pelado de compuesto elaborado con polipropileno y 60% de harina de pino, la resistencia al pelado del WPC sin MAPP fue es 290  24 N/m y con 2,3% de MAPP fue 232 9 N/m; en ambos casos se usó adhesivo acrílico base agua y hubo un tratamiento previo de abrasión.…”

“…Estos materiales ofrecen ventajas sobre los compuestos tradicionales (polímero/carga mineral), tales como alta resistencia y módulo, baja densidad, menor desgaste abrasivo en la maquinaria de proceso (Gardner et al, 2015;Gupta et al, 2007;Kim y Pal, 2010;Oporto et al, 2007). Con respecto a la madera, WPC tienen mejor estabilidad dimensional en condiciones de humedad, mayor resistencia térmica y al ataque microbiano.…”

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.

“…The bonding quality of WPC joints critically affects the strength and life expectancy of the structure (Gramlich et al 2006). Because of the low surface energy (30 mJ/m 2 ), hydrophobic smooth surface and limited functional groups of polyolefins, it is notoriously difficult to achieve a firm adhesion of WPC (Gupta et al 2007). Additionally, the additives (e.g., paraffin) used during the manufacture of WPC further hinder the formation of excellent WPC adhesion interface.…”

Wood-plastic composites (WPC) have been developed into new and important wood-based composites because of their benefits for the environment, economy, and recyclability. When combined with structural adhesives, WPCs will have a greatly broadened application in the construction field. In this work, epoxy resin and acrylic ester were used to bond WPC adhesive joints. The shear strength of the adhesive joints was determined and investigated. Resonant frequency and dynamic modulus of elasticity (MOE) of the WPC adhesive joints were measured using the longitudinal vibration method. The correlation between different vibration parameters and shear strength of WPC adhesive joints was also investigated. Results showed that the epoxy resin had a better bonding quality than the acrylic ester on the bonding of WPC adhesive joints. The resonant frequency, dynamic MOE, and the dynamic MOE ratio of the WPC adhesive joints had close correlations with their shear strength for the samples bonded with epoxy resin.
