Abstract
Official abstract text for this publication.
Provided are: a resin composition that can be given excellent formability and wear resistance when used as a friction material or the like; and a method for producing the resin compound. A titanate compound, which is a salt of at least one element selected from the group consisting of alkali metals and alkaline earth metals, is dispersively contained in a thermosetting resin prior to curing.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a resin composition, the method comprising the steps of: preparing the thermosetting resin in liquid form; mixing a titanate compound into the thermosetting resin in liquid form to disperse the titanate compound thereinto; and adding a hardener to the thermosetting resin composition containing the titanate compound. 2. The method for producing the resin composition according to claim 1 , wherein the step of preparing the thermosetting resin in liquid form includes a step of liquefying the thermosetting resin by melting the thermosetting resin by application of heat. 3. A method for producing a friction material, the method comprising the steps of: producing a resin composition; adding a hardener to the resin composition, followed by grinding into a ground product; preparing a composition for a friction material using the ground product; and thermoforming the composition for a friction material to produce a friction material, wherein the step of producing the resin composition comprises: preparing the thermosetting resin in liquid form, and mixing the titanate compound into the thermosetting resin in liquid form to disperse the titanate compound thereinto. 4. The method for producing the resin composition according to claim 3 , wherein the step of preparing the thermosetting resin in liquid form includes the step of liquefying the thermosetting resin by melting the thermosetting resin by application of heat. 5. The method for producing a friction material according to claim 3 , wherein the titanate compound has an alkaline elution rate of 2% by mass or more. 6. The method for producing a friction material according to claim 3 , wherein the titanate compound has an alkaline elution rate of less than 2% by mass. 7. The method for producing a friction material according to claim 3 , wherein the titanate compound is a salt of at least one element selected from the group consisting of alkali metals and alkaline earth metals. 8. The method for producing a friction material according to claim 3 , wherein the thermosetting resin is a phenolic resin. 9. The method for producing the resin composition according to claim 1 , wherein the titanate compound has an alkaline elution rate of 2% by mass or more. 10. The method for producing the resin composition according to claim 1 , wherein the titanate compound has an alkaline elution rate of less than 2% by mass. 11. The method for producing the resin composition according to claim 1 , wherein the titanate compound is a salt of at least one element selected from the group consisting of alkali metals and alkaline earth metals. 12. The method for producing the resin composition according to claim 1 , wherein the thermosetting resin is a phenolic resin.
