Pneumatic tire having a rubber component containing a rubber gel and starch composite

Abstract: A pneumatic tire having a rubber component comprised of (A) 100 parts by weight (phr) of a rubber containing olefinic unsaturation; (B) from 0 to 100 phr of a filler selected from carbon black and silica; and (C) from 5 to 50 phr of a starch/plasticizer composite and a rubber gel selected from the group consisting of polybutadiene gel, styrene butadiene gel, acrylonitrile-butadiene gel, chloroprene gel, natural rubber gel, and mixtures thereof, wherein the weight ratio of starch/composite to rubber gel is from about 10:1 to about 1:10.

Synthesis and characterization of in situ sodium‐activated and organomodified bentonite clay/styrene–butadiene rubber nanocomposites by a latex blending technique

Abstract: In this article, we describe a method used to prepare an in situ sodium-activated, organomodified bentonite clay/styrene–butadiene rubber nanocomposite master batch via a latex blending technique. The clay master batch was used for compound formulation. Octadecyl amine was used as an organic intercalate. The clay was purchased from local suppliers and was very cheap. Sodium chloride was used for in situ activation of the clay. The wide-angle X-ray diffraction data indicated that the in situ sodium activation helped to increase the intergallery distance from 1.28 to 1.88 nm. A transmission electron micrograph indicated intercalation and partial exfoliation. The thermal properties were relatively better in the case of the sodium-activated, organomodified bentonite-clay-containing compound. A substantial improvement in physical properties such as the modulus, tensile strength, tear strength, and elongation at break was observed in the case of the in situ sodium-activated compound. A cation-exchange capacity equivalent (of the clay) of 1.5 times the octadecyl amine was the optimum dose for the modification. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009

Asphalt self-adhesive and high-polymer self-adhesion rubber waterproof coiled material prepared from asphalt self-adhesive

Abstract: The invention discloses asphalt self-adhesive. The asphalt self-adhesive comprises the following components in percentage by weight: 45 to 65 percent of asphalt, 16 to 25 percent of rubber oil, 5 to 15 percent of styrene butadiene styrene (SBS), 1 to 6 percent of styrene butadiene rubber (SBR), 1 to 6 percent of petroleum resin, 1 to 7 percent of ethylene vinyl acetate (EVA), and 10 to 20 percent of talcpowder. The invention also provides a high-polymer self-adhesion rubber waterproof coiled material which comprises a non-woven fabric coating, a high-polymer sheet coating, and an asphalt self-adhesive coating which consists of the asphalt self-adhesive from bottom to top. Two ends of the waterproof coiled material are provided with joint sides. The asphalt self-adhesive contains EVA, so the compatibility of the self-adhesive and a high-polymer sheet is improved, and compounding intensity of the high-polymer sheet coating is improved. The problem that the high-polymer sheets cannot be jointed reliably in a self-adhesion joint process is solved, so the coiled materials are jointed by the adhesive; and the coiled materials can be adhered firmly and reliably, and adjusted freely and flexibly.
