| 摘要 |
A polyurethane elastic layered material contains hydroxyl polyethers, diisocyanates, solvent and dihydrazides of carboxylic acids as chain extenders (isophthalic acid dihydrazid) and 1,4-di-N-oxide 2,3-bis(oxymethyl)quinoxaline (1 outer layer). The material contains granulated stone activated carbon preliminary saturated with solvent (isopropyl alcohol/hexane) which is distributed over the prepared film (II medium layer) and foamed polyurethane layer (III outer layer) containing water, diazobicyclooctane, paraffinic oil and organosilicone block copolymer SEP-2, stannum octoate, polyethers and polyesters of molecular weight of 500-5000, DNOOQ, polyacrylic acid sodium salt and isicyanate component as mixture of prepolymer based on 2,4-(2,6)-toluyldiisocyanate (TDI) and polyethet of molecular weight of 1000 (L-1000) and TDI. |
