摘要
以稻壳粉、低密度聚乙烯为原料,对比研究润滑剂和偶联剂对复合材料相容性、加工性能和力学性能等方面的影响.实验表明:润滑剂处理的稻壳粉疏水性更好,其中由乙撑双硬脂酸酰胺处理前后的稻壳粉接触角变化为9°;偶联剂的加入对复合材料的力学性能影响较大,其中加入KH570偶联剂时,复合材料的综合力学性能较好,抗拉强度提高了45%,断裂伸长率提高了323.7%,弯曲强度提高了8%,弯曲模量提高了28%;加入钛酸酯偶联剂时,材料的冲击强度提高了62.51%;而润滑剂对材料的加工流变性的提升效果更好,其中加入乙撑双硬脂酸酰胺的转矩最低.
Using rice husk powder and low-density polyethylene as raw materials,the effects of lubricants and coupling agents on the compatibility,processing properties and mechanical properties of composite materials were compared.The results show that the rice husk powder treated with lubricant is more hydrophobic,and the change of contact angle of rice husk powder before and after treatment with ethylenebisstearic acid amide is 9°.The addition of coupling agent has a great impact on the mechanical properties of the composites.When KH570 coupling agent is added,the comprehensive mechanical properties of the composites are better.The tensile strength is increased by 45%,the elongation at break is increased by 323.7%,the bending strength is increased by 8%,and the bending modulus is increased by 28%.When the titanate coupling agent is added,the impact strength of the material is increased by 62.51%.The lubricant has a better effect on the processing rheology of the material,and the torque added with ethylene bisstearic acid amide is the lowest.
