    摘要: The invention provides a colorable roofing membrane comprising fibrous material and a non-bituminous binder comprising: i. a bitumen-like compound having a penetration value of at least 30 units at 25° C., and comprising at least a hydrogenated petroleum resin (a) or comprising at least a hydrogenated petroleum resin (a) and an oil (b), ii. from 10 to 25 parts by weight on 100 parts of the bitumen-like compound of a hydrogenated styrenic block copolymer (c) of formula A-C-A or (A-C′)n—X, wherein A stands for a polymer block of a vinyl aromatic monomer, X stands for a coupling moiety, n stands for an integer of 2 to 20, and C respectively C′ stand for a polymer block of a conjugated diene monomer, hydrogenated to an extent of at least 50% wherein the total amount of A in block copolymer (c) is in the range of from 22 to 40 weight % and wherein the block copolymer has an apparent molecular weight of from 140,000 to 300,000 (A-C-A), respectively of from n*70,000 to n*150,000 ((A-C′)n—X), wherein component i. and ii. together form 50 to 70% by weight of the total binder, the remainder of the binder being based on iii. from 30 to 50% by weight on the total binder of a pigment and/or filler, and iv. from 0 to 4% by weight on the total binder of a UV stabilizer. The invention also provides the non-bituminous, colorable binder composition for making the roofing membrane.
