摘要： Asphalt modifier packages and rubber modified asphalts including the packages are described. Asphalt modifier packages can include an amine functionalized wax and an elastomeric polymer in conjunction with ground tire rubber. Asphalt modifiers can include a ground tire rubber compounded with a reactive elastomeric terpolymer. Rubber modified asphalts can exhibit an excellent stability of the ground tire rubber additive. Rubber modified asphalts can exhibit a storage stability separation factor of about 6°F or less, an MSCR Jnr value of from about 0.05 to about 2 at 3.2 kPa and 67°C, and an MSCR percent recovery of from about 20% to about 75% at 3.2 kPa and 67°C.

摘要： A method of functionalizing reclaimed elastomer material is described. The method involves subjecting particles of the reclaimed elastomer material to shear at temperatures less than 100 C such that inter-chain bonds of the reclaimed elastomer material are cleaved wherein the particles of the reclaimed elastomer material have a size of 60 mesh or smaller. The reclaimed elastomer material can be subjected to shear in the presence of a modifier which selectively promotes the cleavage of inter-chain bonds in the reclaimed elastomer material. A functionalized reclaimed elastomer material made by a method as described above and an elastomer compound which comprises the functionalized reclaimed elastomer material are also described.

摘要： Elastomer compositions comprising uncured elastomer and reclaimed elastomer are described. In one embodiment, the compositions comprise reclaimed elastomer material (micronized rubber powder) of broad particle size distribution, which is less expensive than traditional reclaimed elastomer material with narrow particle size distribution. Further, compositions comprising reclaimed elastomer materials with broad particle size distribution perform comparably to those comprising reclaimed elastomer materials with narrow particle size distribution. In other embodiments, the compositions comprise both vulcanized and devulcanized elastomer materials. Advantageously, by using a combination of vulcanized and devulcanized material, it is possible to incorporate a greater percentage by weight of reclaimed material in to an elastomer composition, thus providing additional cost savings while maintaining high levels of mechanical properties. Further, the use of the reclaimed material reduces landfill waste resulting in a more environmentally friendly product.
摘要翻译：描述了包含未固化的弹性体和再生弹性体的弹性体组合物。在一个实施方案中，组合物包含具有宽粒度分布的再生弹性体材料（微粉化橡胶粉末），其比具有窄粒度分布的传统回收弹性体材料便宜。此外，包含具有宽粒度分布的再生弹性体材料的组合物与包含具有窄粒度分布的再生弹性体材料的组合物相当。在其它实施方案中，组合物包含硫化和脱硫弹性体材料。有利地，通过使用硫化和脱硫材料的组合，可以将更大百分比的回收材料加入到弹性体组合物中，从而在保持高水平的机械性能的同时提供额外的成本节约。此外，回收材料的使用减少了填埋废物，从而产生了更环保的产品。

摘要： Curable elastomer compositions are described which include particles of reclaimed elastomeric material having a particle size of 60 mesh or smaller, sulfur and one or more accelerators, wherein the ratio by weight of the one or more accelerators to sulfur in the composition is at least 1:1. Curable styrene butadiene rubber (SBR) elastomer compositions are also described which include reclaimed elastomeric material, sulfur and one or more accelerators, wherein the ratio by weight of the one or more accelerators to sulfur in the composition is at least 1:1.

摘要： A process of producing powder rubber having a particle size in the range of between about 50 microns and 180 microns is described. The process removes metal, fiber and other foreign materials from ground used tire rubber particles. The processed used tire rubber particles are embrittled by contact with a cryogenic liquid. The embrittled rubber particles are milled in a conical mill. The comminuted rubber particles exit the conical mill at a temperature in the range of between -15 degrees C and -30 degrees C. The powder rubber produced can vulcanize as easily or even more easily than virgin rubber.

摘要： An impact mill (100) including a base portion on which is disposed a rotor (3) rotatably mounted in a bearing housing, the rotor having an upwardly aligned cylindrical surface portion coaxial with the rotational axis. The impact mill includes a mill casing within which is located a conical track assembly (5) surrounding the rotor to form a conical grinding path. The mill casing includes a downwardly aligned cylindrical collar (11) which may be axially adjusted to set a grinding gap (S) between the rotor and the mill casing. The rotor includes a plurality of impact knives complementary with a plurality of impact knives disposed on the inside top surface of the mill casing. The conical track assembly (5) can be a series of assembled conical sections or one unit with varied number of serrations in either a vertical or sloped configuration. This flexibility allows for greater compatibility with the feedstock being milled.

摘要： Thermoplastic elastomers comprising micronized or pulverized rubber powders are disclosed having physical properties equivalent to those of virgin thermoplastic elastomers. For example, the use of finer mesh MRP (e.g., particles of size that would pass through 40 mesh or smaller) to manufacture thermoplastic elastomers results in thermoplastic elastomers that have physical properties equivalent to those of virgin thermoplastic elastomers. Similarly, the use of an glycidyl functional terpolymer (optionally in combination with trimellitic anhydride or "TMA") to manufacture thermoplastic elastomers comprising MRP results in thermoplastic elastomers that have physical properties equivalent to those of virgin thermoplastic elastomers. Moreover, the use of styrene-ethylene/butylene-styrene thermoplastic (e.g., "SEBS") in place of the base polypropylene thermoplastic elastomer to manufacture thermoplastic elastomers comprising MRP also results in thermoplastic elastomers that have physical properties equivalent to those of virgin thermoplastic elastomers.
