Abstract
Provided is a silane coupling agent composition with which it is possible to obtain a rubber composition having excellent scorch resistance and a crosslinked product of a rubber composition having excellent viscoelastic properties. The silane coupling agent composition of the invention includes a silane compound and a protein denaturant and/or a silanization reaction accelerator, in which the silane compound includes a first silane compound represented by the following Formula (1) and a second silane compound represented by the following Formula (11):
Claims17

- L is a hydrocarbon group optionally containing at least one heteroatom selected from the group consisting of nitrogen, oxygen, and sulfur;
- a is an integer of 0 or 1;
- b is an integer of 0 or 1;
- c is independently an integer of 0 or 1;
- d is independently an integer of 0 or 1;
- e is an integer of 0 to 5;
- R4, R5, R6, and R7 represent a hydrogen atom, a methyl group, or an alkyl group having 2 to 10 carbon atoms, or one of R4 or R5 and R6 or R7 optionally forms a crosslinked structure represented by —(CH2)f—;
- f is an integer of 1 to 5;
- R8, R9, R10, and R11 represent a hydrogen atom, a methyl group, or an alkyl group having 2 to 10 carbon atoms, or one of R8 or R9 and R10 or R11 optionally forms a crosslinked structure represented by —(CH2)g—;
- g is an integer of 1 to 5;
- R16 is a hydrogen atom, a methyl group, or an alkyl group having 2 to 8 carbon atoms, while R17 is a hydrogen atom, a methyl group, or an alkyl group having 2 to 10 carbon atoms, and at the same time, R12 and R13 combine with each other to form a double bond, while R14, R15, and R18 are a hydrogen atom, a methyl group, or an alkyl group having 2 to 10 carbon atoms, or R14 and R15 combine with each other to form a double bond, while R12, R13, and R18 are a hydrogen atom, a methyl group, or an alkyl group having 2 to 10 carbon atoms;
- or
- R16 and R17 optionally combine with each other to form a 4- to 9-membered alicyclic hydrocarbon, and at the same time, R14 and R15 combine with each other to form a double bond, while R12, R13, and R18 are a hydrogen atom, a methyl group, or an alkyl group having 2 to 10 carbon atoms,
- and
- a second silane compound represented by the following Formula (11):
- wherein
- R1, R2, and R3 each independently represent a hydrocarbon group optionally containing an oxygen atom or a nitrogen atom, or a hydrogen atom;
- L is independently a hydrocarbon group optionally containing at least one heteroatom selected from the group consisting of nitrogen, oxygen, and sulfur;
- a is an integer of 0 or 1;
- b is an integer of 0 or 1;

- d is independently an integer of 0 or 1;
- e is an integer of 0 to 5;
- R4, R5, R6, and R7 represent a hydrogen atom, a methyl group, or an alkyl group having 2 to 10 carbon atoms, or one of R4 or R5 and R6 or R7 optionally forms a crosslinked structure represented by —(CH2)f—;
- f is an integer of 1 to 5;
- R8, R9, R10, and R11 represent a hydrogen atom, a methyl group, or an alkyl group having 2 to 10 carbon atoms, or one of R8 or R9 and R10 or R11 optionally forms a crosslinked structure represented by —(CH2)g—;
- g is an integer of 1 to 5;
