Abstract

The project involves the development of a permanent adhesive glue resistant to bad weather. Based on previous experience the base used is polyolefin and polyisobutilene elastomers as these are almost totally saturated and offer high resistance to oxidation in atmospheric conditions. The elastomers mentioned must be mixed with synthetic hydrocarbon resins and plastifying oils. The basic compositions (elastomer + tackfier) in a sealed mixer (Bambury) to lower the fusion point of the elastomers. The final compositions of the formulations will be done in heated open boiler. The adhesives obtained will be analyzed for viscosity at temperatures of 1200ºC and 1500ºC, using Brookfield viscosimeter, and softening point, using equipment appropriate for the test. The melted adhesives will be placed on polystyrene sheets with the appropriate format, using the Hot Melt applicator. After cooling, they will be analyzed for initial adhesion with an Emic dynamometer and force of static shearing, using a weight of 1 kilogram per square inch of surface. The result will be the best formulation for the production of a pilot batch which will be evaluated and aged – both real time and accelerated – for three months in a forced air circulation oven. On the basis of good results obtained in the first phase of the project, in the second it is intended to develop and produce glue traps for mice, cockroaches and flies. (AU)
