Material for conveyor belt

Abstract

Abstract PURPOSE:A resin material which can form a conveyor belt excellent in an effect of preventing adhesion of a sticky material, containing a specified microencapsulated adhesion-preventing agent. CONSTITUTION:An adhesion-preventing agent having the following properties: (i) an SP value of 6.5-10.5, (ii) a b.p. (atmospheric) >=200 deg.C, (iii) the adhesive force (25 deg.C) of its blend with bitumen (1:1 by weight) is below 0.35 time that of bitumen itself, and (iv) the amount of bleeding (20 deg.CX24hr) to the surface of a sheet- like sample (NBR 100pts.wt., HAF carbon 60pts.wt., and adhesion-preventing agent 30pts.wt.) is 0.03-15mg/cm<2>, preferably, an organic carboxylic acid ester having the above property, e.g., butyl oleate, is coated with gelatin, polyvinyl alcohol, or the like to form microcapsules. These microcapsules are added to a rubber material or a plastic material to obtain a material for conveyor belts.
