Abstract
La finalidad de este proyecto consiste en llevar a cabo un análisis, desde un punto de vista energético, del curado de los adhesivos.
Se pretende unificar la evolución del proceso de polimerización característico de una serie de
adhesivos con la evolución de los valores correspondientes a la tensión superficial. Para ello se
va a utilizar una serie de métodos aplicables en la determinación de esta propiedad en los líquidos
y algunos sólidos.
No se busca obtener datos experimentales exactos, sino comprobar la correlación que se produce en
la polimerización, para así llegar a obtener conclusiones que nos permitan utilizar valores de
tensión superficial en la modificación, producción, mejora y desarrollo de los adhesivos.
El análisis se desarrollará en distintos adhesivos, cada uno de ellos con un tipo de curado
distinto, para verificar que independientemente del proceso que desarrollen, exista relación en la
evolución del proceso.
The purpose of this project is to carry out an analysis, from an energy standpoint, of the curing adhesives process. It is intended to unify the characteristic evolution of the polymerization process of a range of adhesives with the corresponding surface tension values. To do this, we will use a number of methods applicable in the determination of this property in liquids and some solids. The main goal is not to obtain accurate experimental data, but to check the correlation that occurs in the polymerization, in order to reach conclusions which will lead us to use surface tension values in the modification, production, improvement and development of adhesives. The analysis is performed on different adhesives, each with different curing type, to verify that regardless of the process to develop, there is a relationship in the process evolution.
