摘要:
The present invention relates to a cross-linkable rubber composition, a cross-linked rubber composition obtained by cross-linking such a rubber composition, a method of preparing a tyre and a tyre. The cross-linkable rubber composition comprises, per hundred parts by weight of rubber (phr): ≥ 10 phr to ≤ 20 phr of a natural rubber or an isoprene rubber or a combination thereof; a filler; a resin, and first and second coupling agents, wherein the first coupling agent is a mercaptosilane and the second coupling agent is a silane selected from a disulfide silane, a tetrasulfide silane, or a combination thereof, wherein the rubber composition comprises ≥ 80 phr to ≤ 90 phr of a solution polymerized styrene-butadiene rubber (SSBR) comprising an alkoxysilane group and a primary amino group, and wherein the weight by weight ratio of the mercaptosilane to the silane is in a range of ≥ 2:1 to ≤ 4:1.

The invention relates to a method for providing a tire with an informative label. The method comprises supporting a tire, supplying a banding material to the tire and wrapping it in a loop around a part of the tire, holding the banding material at the neck of said loop, and connecting opposed areas of the banding material at said neck to form a label wrap. The invention further relates to an apparatus for carrying out the method and to a tire provided with the label. The informative label is easily removed by a mechanic and shows an improved processability and printability. The informative label further does not leave any adhesive or other residuals on a tire.

The invention relates to a method for manufacturing a molded article (11) of a rubber polymer to which another article (12) is detachably connected. The method comprises the steps of providing a coupling means (2), comprising a first (2a) and second (2b) member, both of which are provided with interlocking elements (21,22) along connectable edges, the interlocking elements (21,22) being configured to interlock in a substantially continuous way along the edges in the connected state, and unlock in the disconnected state; integrating the first member (2a) and the molded article (11), such that its interlocking elements (21) are available for connection; integrating the second member (2b) and the other article (12), such that its interlocking elements (22) are available for connection; and interlocking the interlocking elements (21,22) of the first and second member (2a,2b) to produce the detachable connection between the articles. The invention further relates to a vehicle spoiler (1), portions of which are mutually connected by the method of the invention.

The invention relates to a method for manufacturing a molded article from a first rubber polymer, which molded article comprises an insert from a second rubber polymer. The method comprises the steps of (A) providing an at least partially vulcanized article from the first rubber polymer, the article having a recess that extends in a depth direction and in transverse directions perpendicular to the depth direction, for accommodating the insert; (B) providing an at least partially vulcanized insert from the second rubber polymer, the insert having a shape such that it can be accommodated in the recess; (C) arranging an unvulcanized object from a third rubber polymer in the recess to partly fill the recess; (C) arranging the at least partly vulcanized insert in the recess to obtain an assembly; and (D) vulcanizing the assembly under pressure. The method yields a molded article having an optically sharp interface between the first rubber polymer and the insert.

The present invention relates to a cross-linkable rubber composition, the cross-linkable rubber composition comprising, per hundred parts by weight of rubber (phr): 100 phr of a rubber component comprising a natural rubber or an isoprene rubber or a combination thereof, a white filler, and a black filler. The white filler is a mixture of a first white filler and a second white filler, wherein the first white filler has a BET surface area of 170 m2/g to 180 m2/g measured according to ASTM D6738 and/or the second white filler has a BET surface area of 5 m2/g to 10 m2/g measured according to ASTM D5604.
