| 摘 要：以木質(zhì)素和碳酸鈣為原料，在球磨機上以一定的轉速并按照一定的配比混合濕法球磨制備了木質(zhì)素-碳酸鈣（Lignin-CaCO3）復合物，并將其分別用于丁腈橡膠（NBR）和丁苯橡膠（SBR）中，共混制備了丁腈橡膠／木質(zhì)素-碳酸鈣（NBR／Lignin-CaCO3）和丁苯橡膠／木質(zhì)素-碳酸鈣（SBR／Lignin-CaCO3）復合材料�？疾炝四举|(zhì)素-碳酸鈣（Lignin-CaCO3）復合物的配比、木質(zhì)素-碳酸鈣（Lignin-CaCO3）復合材料的硫化劑用量、硫化溫度對橡膠復合材料力學(xué)性能的影響。在此基礎上，選定了一個(gè)適宜的復合填料組成比例，研究了不同填料份數對橡膠復合材料的力學(xué)性能的影響。研究結果表明：丁腈橡膠／木質(zhì)素-碳酸鈣復合材料中當填料份數為60時(shí)，木質(zhì)素與碳酸鈣之間的配比為30／10，硫化劑用量為2.5 phr，硫化溫度為170℃其綜合性能最好，其中拉伸強度、斷裂伸長(cháng)率、300%定伸應力和硬度分別為18.7 MPa、774%、3.8 MPa和74 HA；丁苯橡膠／木質(zhì)素-碳酸鈣復合材料當填料份數為40時(shí)，當木質(zhì)素與碳酸鈣之間的比例為20／20，硫化劑用量為1.5 phr，硫化溫度為160℃其綜合性能最好，其中拉伸強度、斷裂伸長(cháng)率、300%定伸應力和硬度分別為8.4 MPa、706%、1.1 MPa和48 HA。 |

| Abstract：The Lignin-CaCO3/NBR and Lignin-CaCO3/SBR composites were prepared by machnical blending of NBR or SBR with Lignin-CaCO3, a complex obtained from ball-milling of lignin and CaCO3. The effect of factors was explored including the ratio of lignin to CaCO3, loadings of Lignin-CaCO3, loadings of BIPB and the curing temperature on the mechanical properties of the rubber composites. The experimental results showed that the comprehensive performance of the Lignin-CaCO3/NBR composites was obtained. When the ratio of lignin to CaCO3 was 30 to 10, the loadings of BIPB was 2.5 phr and the curing temperature was 170℃, the tensile strength, elongation at break, 300% modulus and the shore A of Lignin-CaCO3/NBR composites were 18.7 MPa, 774%, 3.8 MPa and 74, respectively. The experimental results also showed that the comprehensive performance of the Lignin-CaCO3/SBR composites was obtained. When the ratio of lignin to CaCO3 was 20 to 20, the loading of BIPB was 1.5 phr and the curing temperature was 160℃, the tensile strength, elongation at break, 300% modulus and the shore A of Lignin-CaCO3/ SBR composites were 8.4 MPa, 706%, 1.1 MPa and 48, respectively. |
