摘　　要：采用正交试验的方法,评价了短切玻璃纤维长度、纤维掺量、甲基硅醇钠掺量3个因素对磷建筑石膏抗折强度、抗压强度、软化系数的影响。结果表明:短切玻璃纤维和甲基硅醇钠的复合改性可以有效提高磷建筑石膏的耐水性能。在短切玻璃纤维长度9 mm,掺量2%,甲基硅醇钠掺量1.5%时,磷建筑石膏的软化系数达到最优。In this paper,orthogonal experiment was used to evaluate the effect of chopped glass fiber length,fiber content,ash sodium alkoxide methyl siliconate three factors on phosphorus gypsum flexural strength,compressive strength,coefficient of softening.The results show that:by chopped glass fibers and sodium methyl silicone compound modified alcohol,can improve the water resistance of gypsum building phosphorus.When the chopped glass fiber length is 9 mm,dosage is 2%,sodium methyl siliconate is 1.5%,softening coefficient of the phosphorus building gypsum is the best.
