Several non-limiting samples of roofing materials were prepared. Exemplary ingredients used to prepare the roofing materials are shown below in Table 1 below.
As shown in Table 1, Roofing Material Sample L of Table 1 was prepared using a mixture (a recycled solvent system) comprising at least one hydronium ion donor (a water and methanol (H2O/MeOH) mixture). A vinyl polymer (polyvinyl butyral (PVB)) and an organic acid (oleic acid) were added to the mixture. The PVB and the oleic acid were reacted in the presence of the H2O/MeOH mixture so as to result in Roofing Material Sample L.
As further shown in Table 1, Roofing Material Samples M, N, O, P, Q of Table 1 were prepared using a mixture (a recycled water-based emulsion) where the at least one hydronium ion donor was water. The recycled water-based emulsion comprised recycled vinyl polymer (PVB). The recycled water-based emulsion was reacted with an organic acid (oleic acid) so as to result in Roofing Material Samples M, N, O, P, Q.
At least some the above samples (as shown in Table 1 above) included at least one reinforcement material in the form of at least one of recycled asphalt shingles (RAS), ground tire rubber (GTR), perlite, or any combination thereof. For at least some of the samples that utilized the GTR as a reinforcement material, the GTR was mixed with the oleic acid as powder before the GTR and the oleic acid were added to the mixture.
In at least some of the above samples (shown in Table 1 above), a portion of the oleic acid, a portion of a used water-based polymer dispersion, or both, were added to the mixture during the reaction.
As further shown in Table 1, Sample C1 was a comparative sample comprising air blown asphalt and at least one filler (i.e., filled air blown asphalt).
Samples L, O, P, Q, and C1 from Example 1 were tested for Tensile Strength according to ASTM D828, Elongation according to ASTM D828, and Tear according to ASTM D1922. Results are shown below in Table 2.
