Abstract

Provided is a lepidocrocite-type titanate capable of suppressing the interference with the curing of a thermosetting resin and a resin composition having excellent wear resistance. A lepidocrocite-type titanate has a layered structure formed by chains of TiO6 octahedra, wherein part of Ti sites is substituted with ions of two or more metals selected from the group consisting of Li, Mg, Zn, Ni, Cu, Fe, Al, Ga, and Mn and runs of at least one metal selected from alkali metals other than Li are contained between layers of the layered structure.

First claim

The invention claimed is:

1. A resin composition containing:
a lepidocrocite-type titanate having a layered structure formed by chains of TiO 6 octahedra, wherein part of Ti sites is substituted with ions of two or more metals selected from the group consisting of Li, Mg, Zn, Ni, Cu, Fe, Al, Ga, and Mn and ions of at least one metal selected from alkali metals other than Li are contained between layers of the layered structure; and
a thermosetting resin.

2. The resin composition according to claim 1 , wherein 10 to 40% by mole of the Ti sites is substituted with ions of two or more metals selected from the group consisting of Li, Mg, Zn, Ni, Cu, Fe, Al, Ga, and Mn.

3. The resin composition according to claim 1 , wherein the ions of the two or more metals are Li ions and ions of one or more of the metals other than Li.

4. The resin composition according to claim 1 , being represented by a composition formula, A 0.5 to 0.7 Li 0.27-x M y Ti 1.73-z O 3.85 to 3.95 , where A is an alkali metal other than lithium; M is at least one metal selected from the group consisting of Mg, Zn, Ni, Cu, Fe, Al, Ga, and Mn (except for any combination of two or more metals having different valences of ions); when M is a divalent metal, x=2y/3 and z=y/3; and when M is a trivalent metal, x=y/3, z=2y/3, and 0.004≤y≤0.4.

5. A resin composition containing:
a lepidocrocite-type titanate having a layered structure formed by chains of TiO 6 octahedra, wherein part of Ti sites is substituted with ions of two or more metals selected from the group consisting of Li, Mg, Zn, Ni, Cu, Al, Ga, and Mn and ions of at least one metal selected from alkali metals other than Li are contained between layers of the layered structure; and
a thermosetting resin.

6. A friction material containing the resin composition according to claim 1 .
