Silane coupling agent composition for rubber with improved properties
A recently filed patent (Publication Number: US20230312879A1) describes a silane coupling agent composition that can be used in rubber compositions, particularly for tire treads. The composition includes a silane compound, a protein denaturant, and/or a silanization reaction accelerator. The silane compound is represented by Formula (1) and can also be a compound represented by Formula (2).
The composition may also include a protein denaturant, which can be a carbamide compound, a guanidine compound, or a surfactant. Additionally, a silanization reaction accelerator can be included, which can be a carbamide compound or a guanidine compound.
The patent claims that the composition is suitable for use with natural rubber and/or synthetic isoprene rubber. It can be used in a rubber composition that also includes a diene-based rubber and silica. The content of the protein denaturant in the rubber composition is specified to be from 0.01 to 10 parts by mass with respect to 100 parts by mass of the diene-based rubber. The content of silica is specified to be from 5 to 100 parts by mass with respect to 100 parts by mass of the diene-based rubber.
The rubber composition described in the patent can be used for tire manufacturing. It can be used to produce a crosslinked product, which can then be used as a tire tread. The patent does not provide further details about the specific advantages or properties of the composition or the resulting tire tread.
In summary, the patent describes a silane coupling agent composition that can be used in rubber compositions, particularly for tire treads. The composition includes a silane compound, a protein denaturant, and/or a silanization reaction accelerator. It is suitable for use with natural rubber and/or synthetic isoprene rubber and can be used in a rubber composition that also includes a diene-based rubber and silica. The resulting rubber composition can be used for tire manufacturing, specifically for tire treads.
