Abstract

Polychloroprene liquid adhesives are widely used in packaging industries. These types of liquid adhesives are widely used to connect carton and cartonplast boxes, wooden and metal boxes, while the price of this liquid adhesive is relatively low. The viscosity of the liquid adhesive is influenced by adhesion properties. As the temperature changes, the viscosity of the adhesive changes and as a result the adhesion and bonding properties will change. In this study, using Brookfield type viscometer at a temperature range of 15-30 °C, the viscosity of this type of liquid adhesive is measured experimentally, and in order to reduce the test time and avoid the cost of the test, the experimental data of viscosity isregressed to the Vogel theory model and also is fitted to determine the reasonable viscosity. In this case, viscosity can be readily achieved by calculating the viscosity with the Vogel theory model at the desired temperature fast. The results of this study showed that the percentage error of experimental viscosity and the calculated viscosity of polychloroprene liquid adhesive is in the range of 0.03-2.63%, which is very acceptable percentage of error compared to other theories. Therefore instead of performing the long stages of the experimental to determine the polychloroprene liquid adhesive viscosity, using the Vogel theory model to obtain and predict the best conditions for bonding the surfaces with this liquid glue easily.
