摘　　要：为改善玻璃纤维湿法非织造薄毡的物理性能,将木浆纤维、玻璃纤维,按1∶9,2∶8,3∶7,4∶6,5∶5混合,其中木浆纤维打浆度为15°SR,25°SR,35°SR,45°SR,55°SR,利用湿法非织造技术,生产25种玻璃纤维/木浆纤维湿法非织造薄毡.综合测试结果表明,木浆纤维的加入可以显著改善玻璃纤维湿法非织造薄毡的强力、断裂伸长率及耐折性能,而打浆度大小对这些性能影响相对较小;随着木浆纤维含量的增加,其透气性能和阻燃性会下降;木浆纤维最佳的添加比例为30%,此时其拉伸性和耐折性大幅度提高,阻燃性达到一级,且具有良好的透气性.The proposed method is to improve the physical properties of wet-laid nonwoven glass fiber mat. Such raw materials as wood pulp fiber and glass fiber are mixed with the ratio of 1：9, 2：8, 3：7, 4：6, 5：5, with the pulp beating degree of 15°SR, 25°SR, 35°SR, 45°SR, 55°SR respectively. 25 kinds of wood pulp fiber / wet-laid nonwoven glass fiber mat are produced by using wet-laid nonwoven production technology. The results show that the wood pulp fiber can significantly improve the strength, breaking elongation ration and fold-resistance of the wet-laid glass fiber mat, but the pulp beating degree has relatively small effect. With the increase of wood pulp fiber, air permeability and flame resistance decrease. When the optimum proportion of wood pulp fiber is 30%, the tensile strength and fold-resistance greatly improve, flame resistance reaches the top level, and air permeability functions well.
