| 摘要 |
There is disclosed a conveyor belt comprising a bottom fabric layer (2) having a lower first surface (26) forming a backside of said conveyor belt and an upper first surface (25), characterised in that said lower first surface (26) is impregnated with an impregnation (1) comprising: a) one or more thermoplastic polyolefins selected from the group consisting of ethene homopolymers, propene homopolymers, ethene/ ± -olefin copolymers, propene/ ± -olefin copolymers and terpolymers of ethene with two or more different ± -olefins; and b) a thermoplastic polymeric dispersing agent containing repetitive units derived from at least one ethylenically unsaturated monomer of a comparatively lipophilic nature and from at least one ethylenically unsaturated monomer of a comparatively hydrophilic nature and carring an anionic carboxylate group. Also disclosed is a process for the manufacture of such belts comprising applying the thermoplastic polyolefin(s) and the thermoplastic polymeric dispersing agent as an aqueous dispersion and heating the lower first surface (26) having the dispersion applied thereonto. |
