Patent ID: 7851523

Claim:
A process for the preparation of asphalt waterproof composition containing waste tire chips and bentonite, the process for the preparation of asphalt waterproof composition comprising the steps of: (1) mixing and heating about 10-15 of asphalt, about 20-50 of oil, about 8-12 of filler, about 1-3.5 of rubber and about 0.1-0.5 of surface-active agents, in percent by weight, respectively at a temperature of about 150°-180° C. to produce a jelly asphalt; (2) mixing and heating the jelly asphalt with about 25-40 of liquefied waste tire chips, about 0.5-1 of sulfur, about 0.05-1 of sulfur vulcanizing agent selected from zinc oxide, stearic acid or oleic acid and about 0.1-0.4 of rubber antiaging agent selected from hindered amines or hindered phenols, in percent by weight, respectively at a temperature of about 150°-180° C. to produce a melting mixture solution; and (3) mixing and agitating the melting mixture solution with about 10-20 of bentonite and about 1-5 of water soluble polymer resin, in percent by weight, respectively, wherein the liquefied waste tire chips are prepared by a method comprising pyrolyzing tire chips.
