Abstract
Official abstract text for this publication.
The present invention addresses the problem of providing a rubber coating composition for use in a conveyor belt, the composition excelling in both peel force and rubber sticking and having excellent canvas adhesiveness, and of providing a laminate and a conveyor belt. The rubber coating composition for a conveyor belt of the present invention contains a diene-based rubber component, di-2-benzothiazolyl disulfide, silica, a cresol formaldehyde resin, and a modified etherified methylol melamine. The content amounts of each of the di-2-benzothiazolyl disulfide, silica, cresol formaldehyde resin, and modified etherified methylol melamine are all within predetermined ranges.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rubber coating composition for a conveyor belt, the composition consisting of: a diene-based rubber component; di-2-benzothiazolyl disulfide; silica; a cresol formaldehyde resin; a modified etherified methylol melamine; and at least one components selected from the group consisting of an additional filler, sulfur, one or more vulcanization accelerating aids, one or more anti-aging agents, and one or more softening agents; wherein a content amount of the di-2-benzothiazolyl disulfide is from 0.25 parts by mass to 3.0 parts by mass per 100 parts by mass of the diene-based rubber component; a content amount of the silica is from 5.0 parts by mass to 15.0 parts by mass per 100 parts by mass of the diene rubber component; a content amount of the cresol formaldehyde resin is from 1 part by mass to 5 parts by mass per 100 parts by mass of the diene-based rubber component; and a content amount of the modified etherified methylol melamine is from 1 part by mass to 4 parts by mass per 100 parts by mass of the diene-based rubber component. 2. A laminate comprising: a canvas, and rubber coating layers provided on both sides of the canvas, each of the rubber coating layers being a rubber layer that is formed using the rubber coating composition for a conveyor belt according to claim 1 . 3. The laminate according to claim 2 , wherein the canvas comprises nylon fibers or polyester fibers. 4. A conveyor belt comprising an upper surface cover rubber layer, a laminate according to claim 2 , and a lower surface cover rubber layer. 5. A conveyor belt comprising an upper surface cover rubber layer, a laminate according to claim 3 , and a lower surface cover rubber layer.
