摘要:
An applique (11, 14, 31, 32, 33, 34) having a vulcanizable adhesive layer is co-cured on a rubber article by precuring the applique (11, 14, 31, 32, 33, 34) of predominantly pale natural rubber optionally imprinted with a bar code; coating the upper surface of the applique with a protective self-supporting film of polyamide less than 0.050 mm thick, or a non-self-supporting film of polyurethane less than 25.4 µm thick; adhering the applique (11, 14, 31, 32, 33, 34) to the article at a chosen location; curing the article in a curing mold; and, removing a cured article from the mold with the protective film adhering to the surface of the applique (11, 14, 31, 32,33, 34), the surface of which is essentially free from visually observable cracks. The hot flow of rubber in the curing mold does not substantially change the location of the applique which is embedded in the article.

摘要:
This invention relates to a tire with a tread of a cap/base construction with at least one underlying silica-rich, cis 1,4-polyisoprene rubber based intermediate transition rubber layer (4) to promote a reduced internal heat generation.
摘要:
A method of preparing a rubber tire component for use in a tire manufacturing process is disclosed. The process includes providing relative motion between the tire component (10) and a plasma treatment device (12) so as to plasma treat a surface of the tire component (10). The method may be used to increase the tack and/or the adhesion of the tire component (10) so as to eliminate or reduce the use of solvent-based tire cements in the tire manufacturing process. The method may further be used to increase the wettability of the tire component (10) so as to allow water-based compounds, such as water-based tire cements and striping inks, to be used in the tire manufacturing process.
摘要:
The invention relates to an endless vehicular rubber track (1) and more specifically to such track having hard rubber guide lugs (5) with a softer guide support layer (5A). It is to be appreciated that such guide lugs (5) may also be positively driven drive lugs. The invention further relates to a vehicle having such track.
摘要:
The present invention relates to rubber compositions containing an elastomer containing olefinic unsaturation and a bis anil compound of the formula where R 1 and R 2 may be the same or different and are independently selected from alkyls having from 1 to 5 carbon atoms and X is selected from the group consisting of H; OH; OAlk where Alk is an alkyl having from 1 to 3 carbon atoms; COOH; C00 - M + where M is a metal selected from the group consisting of Zn, Na, Ca and Mg; and y is 0 to 2.
摘要:
This invention relates to the discovery that the combination of a hydrated thiosulfate and a bismaleimide compound provides for excellent final rubber vulcanizate physical properties including improved adhesion to aramid reinforcement.
摘要:
A silica reinforced solventless adhesive composition or cushion (14) comprises a blend of rubber, silica, a silica coupling agent, an optional tackifier, and low or nil amounts of carbon black. The elastomeric adhesive composition can be utilized with various other rubber layers to adhere a cured or uncured tire tread (12) to a cured tire casing (16). The elastomeric adhesive composition has good blowout resistance and a very low, final blowout test temperature.
摘要:
A bias ply pneumatic aircraft tire (10) has carcass plies (16) and/or breaker plies (22) which are reinforced by flat nylon monofilaments. The nylon monofilaments in the carcass plies and/or breaker plies have an oblong cross-section, and the following characteristics: at least 2,000 denier, a tenacity of at least 6 g/denier, an initial modulus of at least 30 g/denier and a shrinkage of at most 5%. It has been discovered that bias plied composites made using nylon monofilaments demonstrate a stiffness about 20-50% greater than multifilament composites having the same approximate rivet area. An aircraft tire made using such monofilaments shows good burst strength when built with carcass plies wherein the monofilaments have a concentration of 8-16 EPI. Burst strength properties may be further improved by incorporating such monofilaments in breaker plies at a concentration of 8-14 EPI.
