| 摘要:本研究采用硅烷偶联剂KH550和纤维素纤维对矿渣棉进行表面接枝改性，并将其与阔叶木浆配抄高强度瓦楞原纸。结果表明，KH550通过化学键合作用，显著改善了矿渣棉与纤维素的界面相容性，有效提升了矿渣棉在水相中的分散稳定性。相比纯矿渣棉，KH550/纤维素纤维接枝改性矿渣棉与纤维间的结合力显著增强，制得瓦楞原纸的环压与拉伸性能明显提升。当KH550体积分数为5%、纤维素纤维质量分数为15%时，矿渣棉表面接枝改性效果最优。改性矿渣棉与阔叶木浆质量比15∶85时制备的定量120 g/m2瓦楞原纸的环压指数达4.8 N·m/g，裂断长3.5 km，较纯阔叶木浆制得纸张分别提升29.7%和34.6%。 |
| Abstract:In this study, slag wool was subjected to surface graft modification using silane coupling agent KH550 and cellulose fibers, and corrugated base paper with high strength was prepared via mixing the modified slag wool and hardwood pulp. The results showed that the interfacial interaction between slag wool and hardwood pulp fibers was remarkably improved by KH550 through chemical bonding, and the dispersion stability of slag wool in aqueous phase was effectively enhanced. Compared with unmodified slag wool, the bonding force between KH550/cellulose fiber graft-modified slag wool and hardwood pulp fibers was greatly strengthened, and the ring crush and tensile performances of the prepared corrugated base paper were significantly elevated. The optimum surface graft modification effect on slag wool was achieved when the volume fraction of KH550 was 5% and the mass fraction of cellulose fibers was 15%. Corrugated base paper with a basis weight of 120 g/m² was prepared at a mass ratio of modified slag wool to hardwood pulp of 15∶85, of which the ring crush index reached 4.8 N·m/g and breaking length was 3.5 km, in comparison with the paper made from pure hardwood pulp, which were increased by 29.7% and 34.6%, respectively. |
