Uv-shielding material based on mg-al layered double hydroxide and its application in anti-ageing asphalt

Номер: US20120240821A1
Автор: Jianying Yu, MIN Wei, Shaopeng Wu, Wenying Shi, XUE Duan, Yanjun Lin
Принадлежит: Beijing University of Chemical Technology, Wuhan University of Technology WUT

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: Mg 1-x Al x (OH) 2 (CO 3 ) x/2 .mH 2 O. 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.

Asphalt can be modified by polymers, oligomers, and waxes made from polymeric material. The addition of polymer, oligomer, or wax can increase the softening point of the asphalt, decrease the penetration of the asphalt, and/or shorten the oxidation of the asphalt. In some embodiments, polymer, oligomer, or wax is added to an oxidized asphalt. The polymer, oligomer, or wax can be made by catalytic depolymerization and/or thermal degradation of polymeric material. The polymeric material can be polystyrene, polypropylene, polyethylene, a combination of polypropylene and polyethylene or recycled plastics. In some embodiments, addition of the polymer, oligomer, or wax improves the performance grade of a paving asphalt binder alone or in combination with other modifiers such as ground tire rubber and polymers.

Disclosure relates to modified sulfur, preparation method thereof, preparation equipment thereof. The modified sulfur has spinnability or includes micro-structures such as fiber-, film- and network-like structure. The modified sulfur can be prepared by inducing polymerization with ultrasonic or ageing. The modified sulfur has various excellent features such as anticorrosiveness, waterproofing, strength, and fast drying and can control the features depending on its viscosity or polymerization degree. In addition due to the above features, the modified sulfur can be applied to anticorrosive or waterproofing material and can prepare anticorrosive or waterproofing material which has good workability, hardening, salt spray resistance, and weldability exceeding a certain level, and specially improved adhesiveness. Furthermore, when applying the modified sulfur to asphalt composition, gelation and depression are reduced, properties such as bending strength and tensile strength are improved, and it is possible to obtain asphalt composition with good working stability at RT.

A method for producing a non-coalescing asphalt from raw natural asphalt herein referred to as TLA Cold Milled. Raw TLA is crushed into smaller particles and milled at ambient temperature. The milled TLA is passed through a first sieve to maintain the separation of the particles and to produce a damp milled TLA in a powdered state. The damp milled powdered TLA is dried by exposing it to heat and is thereafter cooled to ambient temperature. The dried and cooled powdered TLA is passed through the first sieve or another sieve to produce the TLA Cold Milled which may be packaged at ambient temperature in conventional bags. The milling of the asphalt results in each particle of inorganic matter within the asphalt being surrounded by bitumen and a thin film of inorganic material, producing asphalt in a non-coalescing form, i.e., the TLA Cold Milled. 1.
