| 摘 要：使用無(wú)水石膏代替碳酸鈣作為填料，與聚氯乙烯（PVC）共混制備了耐酸蝕PVC復合材料。當無(wú)水石膏添加量為40份時(shí)，耐酸蝕PVC復合材料腐蝕度降低為1.63 g/m2，優(yōu)于耐酸蝕PVC腐蝕度要求。該耐酸蝕材料較添加相同份數碳酸鈣的PVC材料相比，熱穩定性增加，開(kāi)始分解溫度提升4 ℃，800 ℃質(zhì)量保留率為碳酸鈣復合材料的1.3倍；拉伸強度為33.80 MPa，提高28.0%；彎曲模量為1 051 MPa，降低13.4%，沖擊強度為8.86 kJ/m2，降低20.0%。 |

| Abstract：Acid corrosion-resistant polyvinyl chloride (PVC) composites were prepared using anhydrous gypsum instead of calcium carbonate as the filler. The advantage was that when the loading of filler is 40, the corrosion degree of the acid corrosion resistant PVC composite material was of 1.63 g/m2, lower than the data required for acid corrosion resistant PVC product. Meanwhile, the decomposition temperature was increased by 4 ℃, and the tensile strength was 33.80 MPa, which was increased by 28.0%. But the bending modulus was 1 051 MPa with a reduction of 13.4%, and the impact strength was 8.86 kJ/m2 with a reduction of 20.0%. |
