Abstract
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.
Claims5
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.
