TREATMENT OF RUBBER TO FORM BITUMINOUS COMPOSITIONS

Rubber, particularly crumb rubber from the recycling of tyres, is processed to effect partial or high levels of dissociation of rubber vulcanate network, in particular to form bituminous compositions in which the treated rubber, carbon black and other additives released are stably dispersed. Bitumen, hydrocarbon oil and liquid rubber are used to effect penetration, swelling and compatibilization of the rubber particles, following which thermal energy and mechanical energy are applied to initiate breakdown of the vulcanized structure of the rubber particles and the formation of at least partially dissociated rubber vulcanate network. Such treated rubber may be further reacted and combined for employment in the production of stabilized polymer modified bitumen composition.

Reclaimed vulcanized rubber

Vulcanized rubber is reclaimed by treating pieces of the rubber to render a surface layer of each piece plastic while the inner core of the piece remains non-plastic. A chemical reagent can be used in the treatment, but it is preferred to render the surface layers of the rubber pieces plastic by a heat treatment which involves direct exposure of the pieces of rubber to either a flame or a heated gas. In a preferred embodiment of the invention vulcanized rubber pieces are dropped under gravity into a flame so that any attached textile residues are burnt away simultaneously with the plasticizing of the surface layers of the pieces, and the heated pieces then enter a stream of cold air which quenches the heat treatment.

The resultant thermoplastic natural rubbers exhibit superior physical properties such as tensile strength, elongation, hardness and flexural modulus compared to thermoplastic rubber compositions comprising mixtures of plastics, NR and recycled rubbers heretofore produced. In one embodiment, the thermoplastic rubbers are prepared from blends of partially vulcanized NR known as Superior Processing rubber in lieu of blends of NR and vulcanized rubber scrap materials for better uniformity and consistency of finished thermoplastic rubber products, and virgin plastic resins.

Process for producing agglomerates comprising rubber and wax, agglomerates produced therefrom and their use in asphalt or bitumen

Bei einem Verfahren zur Herstellung eines Schüttgutes von Agglomeraten aus Gummipartikeln und Wachs wird eine Zusammensetzung des Agglomerats und die Verwendung dieses Schüttgutes für die Herstellung von Asphalt oder Bitumenmassen derart geschaffen, indem Gummi durch Quellung und Verwendung eines Quellmittels aktiviert und eine Schmelze aus viskositätsreduzierendem Wachs und optionalem Polyoctenamer zugegeben wird, die aktivierten Gummipartikel mit dem viskositätsreduzierenden Wachs und optionalen adhäsionsverbessernden Stoffen agglomeriert werden, wobei das Quellungsmittel in die Zwischenräume der Gummimoleküle eindringt und die Moleküle auseinander drängt, die physikalischen Anziehungskräfte verringert oder unterbrochen werden, so daß das resultierende größere Volumen zu einer Viskositätsminderung und die Erweichung zu einer innigeren und homogeneren Benetzung mit dem Wachs führen. In a method for producing a bulk material of agglomerates from rubber particles and wax, a composition of the agglomerate and the use of this bulk material for the production of asphalt or bitumen masses is created in such a way that rubber is activated by swelling and use of a swelling agent and a melt of viscosity-reducing wax and optional Polyoctenamer is added, the activated rubber particles are agglomerated with the viscosity-reducing wax and optional adhesion-improving substances, the swelling agent penetrating into the spaces between the rubber molecules and forcing the molecules apart, the physical forces of attraction being reduced or interrupted, so that the resulting larger volume leads to a viscosity reduction and the softening leads to a more intimate and homogeneous wetting with the wax.

Using excess levels of metal salts to improve properties when incorporating polymers in asphalt

In methods of preparing asphalt and elastomeric polymer compositions such as polymer modified asphalt (PMA), it has been discovered that the compatibility can be improved by adding excess amounts of certain organic and inorganic metal salts beyond the proportions normally used. Suitable metal salts may be metal oxides that include, but are not necessarily limited to, zinc oxide, calcium oxide, and the like. The method of the invention also permits asphalt modified with other polymers such as ground tire rubber (GTR) to have improved compatibility. Additionally, the use of excess amounts of these metal salts helps control gel formation.

Tire crumb-based bitumen polymer for producing a lower viscosity asphalt with improved tolerance to high temperatures

A bitumen polymer additive comprises a base of tire rubber crumbs in the amount of about 70 to about 90 percent by weight of tire rubber crumbs sized about 14 mesh or smaller. Added to that base is about 0.5 to about 5 percent by weight of a benzothiazole-based devulcanizing agent, about 0.3 to about 3 percent by weight of a C 14 -C 18 heavy metal soap such as a zinc stearate, about 0.1 to about 3 percent by weight of an antiozonant, and about 0.1 to about 20 percent of a plasticizer such as a heavy oil. The additive polymer is used for producing an asphalt of superior quality, including lower initial viscosity and improved wear resistance.
