Abstract
Official abstract text for this publication.
An object is to provide a polyurethane transmission belt offering excellent durability, as well as a belt-molding material for manufacturing such transmission belt. As a solution, a polyurethane transmission belt is provided that contains 1,2-cyclohexane dicarboxylic acid diisononyl ester expressed by Chemical Formula (1) below.
First claim
Opening claim text (preview).
What is claimed is: 1. A thermoset-polyurethane transmission belt formed by thermally curing a liquid prepolymer synthesized from polyisocyanate and polyol, wherein the thermoset-polyurethane transmission belt contains 1,2-cyclohexane dicarboxylic acid diisononyl ester expressed by Chemical Formula (1) below by 5 to 40 parts by weight relative to 100 parts by weight of the liquid prepolymer, and a core wire is embedded in the thermoset-polyurethane transmission belt 2. A thermoset-polyurethane transmission belt according to claim 1 , characterized by having a Shore A hardness of 85 to 93. 3. A thermoset-polyurethane transmission belt according to claim 1 , characterized by not containing phthalate ester plasticizer. 4. A thermoset-polyurethane transmission belt according to claim 1 , characterized by being a V belt or toothed belt. 5. A thermoset-polyurethane transmission belt according to claim 2 , characterized by not containing phthalate ester plasticizer. 6. A thermoset-polyurethane transmission belt according to claim 2 , characterized by being a V belt or toothed belt. 7. A thermoset-polyurethane transmission belt according to claim 3 , characterized by being a V belt or toothed belt. 8. A thermoset-polyurethane transmission belt according to claim 5 , characterized by being a V belt or toothed belt.
