A process is provided for converting discarded rubber, e.g., rubber crumb, into absorbent material. The process comprises extruding a mixture of discarded rubber and oxidizer(s) under progressively increasing temperature to reach a temperature above 250 C. The extrudate may undergo a secondary oxidation. The partially devulcanized granular rubber formed is useful as absorbent material for hydrocarbons, e.g., in remediation of contaminated soil and oil spills.

A coating agent for a wiper blade rubber having superior friction performance and wiping performance, both initially and during use for an extended period, and having superior durability by inhibiting wear and the like, and a wiper blade rubber using the same. The coating agent for the wiper blade rubber includes a solid lubricant and a binder containing a polycarbonate-based polyurethane resin. The wiper blade rubber has the coating agent on both lateral surfaces of a lip portion of the wiper blade rubber.

Rubber pellets are coated with an anti-tack material. The anti-tack material may be comprised of a metallic stearate, such as magnesium stearate. The coated rubber pellets are loaded on to a rotational conveyance mechanism that rotates at a speed and radial amount to provide an interaction time between the rubber pellets and the anti-tack material. The coated rubber pellets may then be dried in a centrifuge dryer having a plurality of angled fins extending from a rotational shaft.

The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

Provided is a composition containing two or more resins and a long glass fiber, containing: a resin mixture including two or more unit resins; a long glass fiber with a length of 10 mm or greater; and a rubber-based resin, which contains 3-30 parts by weight of the long glass fiber and 0.5-25 parts by weight of the rubber-based resin based on 100 parts by weight of the resin mixture.

A method for preparing a rubber protective cover of an expressway guardrail includes steps of: (S1), preparing material, wherein the material includes high-temperature vulcanized rubber, nanometer zinc oxide, nanometer silicon dioxide and a modifier; (S2), placing the vulcanized rubber into a mixing furnace which is able to increase a temperature, and then heating to 200 C.; (S3), adding the nanometer zinc oxide, and then stirring for 10 minutes; (S4), adding the nanometer silicon dioxide, and then stirring for 5 minutes; (S5), adding the modifier, and then stirring for 30 minutes; and (S6), adding the rubber after stirring into a four-roll calender, shaping, and preparing the rubber cover having a thickness of 10-20 mm and a length of 300-600 mm. The present invention has a low cost, a corrosion resistance, an easy preparation process, a low equipment requirement and a strong operability.

The invention relates to a rubber composition based on at least one diene elastomer, a reinforcing filler including at least carbon black, having a specific surface area CTAB greater than or equal to 130 m.sup.2/g, a plasticizing hydrocarbon resin, the vitreous transition temperature of which, Tg, is greater than 20 C. and the softening point of which is less than 170 C., and a cross linking system, the dispersion of the filler in the elastomeric matrix having a Z score greater than or equal to 70.

A method of molding a sole (6) in vulcanized foam rubber for footwear, includes preparing a rubber in the form of a strip, preformed and/or granules, mixing the rubber inside a loading and mixing chamber (10), and preparing a mold (4) for the molding of a footwear sole (6). The mold (4) defines a molding chamber (8) counter-shaped with respect to a footwear sole (6). The mixed material is conveyed inside the molding chamber (8) and molding the footwear sole (6) inside the molding chamber (8) and the footwear sole (6) is removed from the mold (4). The rubber includes a foaming agent able to generate an expansion of the material inside the molding chamber (8) during molding, so as to uniformly fill the molding chamber (8) with the foam rubber. The foam material is vulcanized inside the molding chamber (8).
