    • The invention relates to articles of manufacture, such as for example, tires and industrial products, which have at least one component comprised of a rubber composition which contains particles of pre-sulfur vulcanized rubber (e.g. ground recycled rubber) and impure tetrathiodipropionic acid, namely a blend comprised primarily of tetrathiodipropionic acid and trithiodipropionic acids of a weight ratio thereof in a range of about 80/20 to about 30/70. Said blend is referred to herein as an S4/S3 blend. The S4/S3 blend may be introduced directly to a rubber composition or may be provided as particles of a composite of said S4/S3 and a particulate support therefor for a purpose of aiding the dispersion of the S4 and S3 within the elastomer host. Representative of such support, or carrier, may be, for example, silica, particularly amorphous precipitated silica, carbon black, clay, starch, calcium carbonate, calcium silicate, titanium dioxide and the like, wherein carbon black is preferred. It is considered herein that an advantageous nature of the invention is to provide such an S4/S3 blend, for example, in a manner to somewhat depress the melting point of the trithiodipropionic acid and therefore promote its processability and incorporation with particles of pre-vulcanized rubber without substantially degrading any beneficial effect thereof. Thus, the invention is intended to be exclusive of use of 100 percent pure tetrathiodipropionic acid and exclusive of relatively high purity trithiodipropionic acid which contains at least 80 percent trithiodipropionic acid.
    • 本发明涉及制品,例如轮胎和工业产品,其具有至少一种组分,该组分由含有预硫硫化橡胶颗粒(例如研磨回收的橡胶)和不纯的四硫代二丙酸的橡胶组合物组成,即, 主要由四硫代二丙酸和三硫代丙酸组成的共混物,其重量比在约80/20至约30/70的范围内。 所述共混物在本文中称为S4 / S3共混物。 可以将S4 / S3共混物直接引入橡胶组合物中,或者可以作为所述S4 / S3和其颗粒载体的复合材料颗粒提供,用于帮助弹性体主体中的S4和S3的分散。 这种载体或载体的代表可以是例如二氧化硅,特别是无定形沉淀二氧化硅,炭黑,粘土,淀粉,碳酸钙,硅酸钙,二氧化钛等,其中优选碳黑。 在本文中认为,本发明的有利性质是提供这种S4 / S3共混物,例如以稍微降低三硫代丙酸的熔点的方式,从而促进其加工性并与预硫化的颗粒结合 橡胶,其基本上不会降低其任何有益效果。 因此,本发明旨在不包括使用100%纯的四硫代二丙酸,并且不包含含有至少80%的三硫代丙酸的相对高纯度的三硫代二丙酸。

    • This invention relates to a tire with a rubber sidewall having at least one layered rubber composite integral with a portion of its outer surface as a means of visibly identifying the tire. The layered composite is an integral composite in a sense of being comprised of a base rubber layer and a contrastingly colored marking rubber layer being partially pre-cured together prior to application to the outer surface of an uncured rubber sidewall. The integrally layered composite and tire rubber sidewall are integral in a sense of being co-cured together with the surface of the base rubber layer facing the rubber sidewall surface. The base rubber layer is a black colored carbon black reinforced rubber layer. The marking rubber layer is of color which contrasts with the black color of the base rubber layer. The base layer is a protective rubber layer which extends beyond the peripheral edges of said marking layer and is protective in a sense of inhibiting, or retarding, discoloring materials from migrating through it to the contrastingly colored marking layer.
    • 本发明涉及一种具有橡胶侧壁的轮胎,该轮胎具有至少一层分层橡胶复合材料,与其外表面的一部分一体化,作为可视地识别轮胎的手段。 层状复合材料是一种整体复合材料,其意义在于,在施加到未固化的橡胶侧壁的外表面之前,由基底橡胶层和对比着色的标记橡胶层部分预固化在一起。 一体化层叠的复合材料和轮胎橡胶侧壁是一体的,与基体橡胶层的面向橡胶侧壁表面的表面共同固化。 基底橡胶层是黑色的炭黑增强橡胶层。 标记橡胶层具有与基底橡胶层的黑色相反的颜色。 基层是延伸超过所述标记层的周缘的保护性橡胶层,并且是防止或阻碍变色材料从其迁移到对比色标记层的意义上的保护性的。

    • This invention relates to a pneumatic tire having a built-in non-black colored sealant layer and its preparation. The sealant layer is derived from a sealant precursor layer comprised of a butyl rubber, organoperoxide, particulate, synthetic amorphous silica and plant-derived organic agricultural seed flour, together with a non-black colored colorant. The butyl rubber-based sealant precursor layer is build into the tire to form a tire assembly and the butyl rubber component of the sealant precursor layer is depolymerized during a subsequent curing of the tire at an elevated temperature in a suitable mold to form the tire having the resultant built-in sealant. The particulate plant derived organic agricultural seed flour is a renewable raw material in a sense that it can be replenished in nature and therefore not as a significant depletion of non-renewable natural resource. The agricultural plant seed flour is comprised of at least a portion of a ground plant seed (e.g. whole or partial seed portion including for example its nucleus and/or shell) of an agricultural seed producing plant such as, for example, wheat, rye, rice, barley, oat, mullet, soybean and/or corn. The sealant layer may also contain one or more of a liquid polyisoprene and short organic fibers. Preferably, the amorphous silica is a precipitated silica, namely aggregates of primary silica particles.
