Abstract: PURPOSE: To contrive an improvement in stability of a quality of the title product, by making use of a vulcanization bladder whose surface treatment has been performed by a silicon composite containing polyorgano siloxane.
CONSTITUTION: At least two pieces of organic radicals out of the organic radicals of a molecule of polyorgano siloxane possess more than 4 pieces of carbon atoms and is a C=C double-bond hydrocabon radical through one piece of a carbon atom from a silicon atom. As the double-bond hydrocarbon radical is possessed by the molecule, co-crosslinking of organic rubber based on a vulcanizer and the polyorgano silioxane becomes possible. When a silicon composite is used by making the same dissolve by an organic solvent, the composite in a solution is made into 2W50wt%. When the silicon composite is used as an aqueous emulsion, 200W1,800pts.wt. water is used for 100pts.wt. composite. An emulsification stabilizer and surface-active agent are used further for emulsion formation and stabilization. As for the surface-active agent, 2W30pts.wt. is loaded to 100pts.wt. composite. With this construction, generation of a molded defective article is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide natural rubber latex capable of dispersing excellently a viscosity stabilizer giving excellent stable-viscosity effect, natural rubber containing the viscosity stabilizer and a method for preparing them. SOLUTION: Emulsion of the viscosity stabilizer in a solvent of an aliphatic compound having chain structure is added to natural rubber latex and the natural rubber containing the viscosity stabilizer is prepared by drying this natural rubber latex. Dispersibility of the viscosity stabilizer is improved by emulsifying it, giving the stable-viscosity effect. Hydroxylamine hydrosulfate, semicarbazide, dimedon or a hydrazide compound is used as the viscosity stabilizer.

Abstract: PROBLEM TO BE SOLVED: To prevent mud from sticking to a wheel without lowering the driving force of the wheel, regardless of the type of the soil, and especially to minimize taking out of the mud from a marshy district. SOLUTION: A traveling body, which rotates or travels round cyclically, is provided in its tread with a plurality of land parts. In the land part, both the entire surface of a groove part, which partitions the tread land part, and the entire surface of at least a shoulder area, which is adjacent to the groove part, have high repellency, whose contact angle is greater than 95 deg., while the groove part is provided with a mud-separation accelerator. In this case, the mud-separation accelerator is made up of a foamed body with the hardness of 2 to 45 by the Asker-C method.

Abstract: PURPOSE:To impart a tire effective flame-resistance and a fire preventive function without impairing any performance of the tire by forming a flame retardant layer, whose oxygen index is 25.0 to 50.0 and whose thickness is 0.005 to 0.3mm, on the outer surface of the tire whose oxygen index at the tread part is 19.8 to 27.5. CONSTITUTION:A flame retardant layer, whose oxygen index is 25.0 to 50.0, is formed on the outside surface, i.e., on the outer skin of the tire including a tread and a side. In this case, preferably, the oxygen index of the flame retardant layer is 28.0 to 45.0, further preferably 30.0 to 40.0. If the oxygen index of the flame retardant layer is less than 25.0, the tire will lack the flame resistance. On the contrary, if it is over 50.0, the tire will lack durability because of an occurrence of cracks. The thickness of the flame retardant layer formed on the outer surface of the tire is 0.3mm or less, preferably 0.005 to 0.25mm. If the thickness exceeds 3mm, the problem of cracks becomes acute, while, if it is less than 0.005mm, the tire will fail in showing effective flame resistance.

Abstract: PURPOSE:To prevent air leakage at the time of puncture and flat tire running itself by providing an adhesive layer having an oxygen index of a specific value or more in an inner surface of a tire. CONSTITUTION:An adhesive layer having an oxygen index of at least 21.0 or more is provided in an inner surface of a tire. This adhesive layer is composed of adhesive rubber for a sealant. Consequently, air leakage is prevented at the time of puncture to prevent flat tire running without impairing a tire property substantiall. Since the adhesive layer is provided in the inner surface of the tire, rubber powder is not generated even in the flat tire running, and further since the adhesive layer is a flame retardant layer, rubber powder ignition is not caused. Even when a fire comes around from other parts, the tire can be provided with a fire prevent ion function.
