Publication number: 20120240821Abstract: The present invention relates to a preparation method for a UV-shielding material based on Mg—Al Layered Double Hydroxide. The material with multi-layered overlay structure is made from Mg—Al double hydroxide layers and interlayer carbonate, its molecular composition is: Mg1-xAlx(OH)2(CO3)x/2.mH2O. The inorganic layers of this material can play a physical shielding role against UV, and the metal elements dispersed on the layer as well as the interlayer anion can play a great role in the chemical absorbing. In addition, by controlling the particle size and the amount of the layers, UV light can be effectively shielded by multi-level reflection and absorption of the multi-level layered structure. Therefore, the material with multi-level chemical and physical shielding properties has a good UV barrier effect for the anti-ageing asphalt, and could significantly increase its UV resistance properties.Type: ApplicationFiled: February 22, 2012Publication date: September 27, 2012Applicants: WUHAN UNIVERSITY OF TECHNOLOGY, Beijing University of Chemical TechnologyInventors: Xue DUAN, Wenying Shi, Min Wei, Yanjun Lin, Shaopeng Wu, Jianying Yu

Publication number: 20090012214Abstract: An asphalt material having improved paving characteristics and processes for its preparation. An asphalt base material is heated in a mixing chamber to a temperature sufficient to melt the asphalt so that it can be stirred. A water-insoluble heavy metal soap is incorporated into the chamber in an amount effective to reduce the PAV-DSR temperature of the asphalt base material by an incremental amount of at least 1° C. Thereafter, the asphalt material is recovered from the mixing chamber to provide an asphalt product containing the heavy metal soap which exhibits a PAV-DSR temperature which is less than the PAV-DSR temperature for the corresponding base material without the addition of the heavy metal soap. The water-insoluble soap is a C14-C18 heavy metal soap such as a C16-C18 zinc- or calcium-based soap including zinc stearate, zinc oleate and zinc palmitate. The heavy metal soap is added to the mixing chamber in an amount within the range of 0.05-3.0 wt.Type: ApplicationFiled: June 27, 2008Publication date: January 8, 2009Applicant: Fina Technology, Inc.Inventors: James Butler, Paul Buras, William Lee

Patent number: 6627065Abstract: Coating compositions and methods of their use are described herein for the reduction of corrosion in imbedded metal structures. The coatings are applied as liquids to an external surface of a substrate in which the metal structures are imbedded. The coatings are subsequently allowed to dry. The liquid applied coatings provide galvanic protection to the imbedded metal structures. Continued protection can be maintained with periodic reapplication of the coating compositions, as necessary, to maintain electrical continuity. Because the coatings may be applied using methods similar to standard paints, and because the coatings are applied to external surfaces of the substrates in which the metal structures are imbedded, the corresponding corrosion protection may be easily maintained. The coating compositions are particularly useful in the protection of metal-reinforced concrete.Type: GrantFiled: October 15, 2001Date of Patent: September 30, 2003Assignee: The United States of America as represented by the Administrator of the National Aeronautics & Space AdministrationInventors: Louis G.
