Title:
CROSSLINKED RUBBER
Document Type and Number:
WIPO Patent Application WO/2019/163772
Kind Code:
A1
Abstract:
Provided is a crosslinked rubber which is obtained by crosslinking a rubber composition containing a conjugated diene-based rubber and an inorganic filler, and which is characterized in that the additivity parameter is 0.36 or less when the loss tangent is measured using an atomic force microscope in a state whereby the crosslinked rubber is subjected to vibration by 10 Hz sine waves, such additivity parameter being determined using formula (A) and from the following: the loss tangent K(m) of a non-interface component of the crosslinked rubber component that forms parts other than an interface with the inorganic filler, and the proportion φ(m) of the non-interface component; and the loss tangent K(i) of an interface component of the crosslinked rubber component that forms an interface with the inorganic filler, and the proportion φ(i) of the interface component. (A): Additivity parameter = K(m)×φ(m)+K(i)×φ(i) (Here, φ(m)+φ(i)=1)
