摘要: 以高吸油树脂为硅橡胶的共混改性剂,添加适量的高吸油树脂后,硅橡胶的力学性能得到了有效改善,其拉伸强度和断裂伸长率都显著提高。通过实验发现,硅橡胶的硬度可通过改变高吸油树脂添加量来调节。同时,改性后的硅橡胶提高了吸油膨胀性能和耐有机溶剂性能。利用高吸油树脂高亲油、吸油膨胀的特性,可以解决硅橡胶在使用中老化、腐蚀变质导致的密封性缺失、材料破损等问题,增加硅橡胶材料的使用寿命。Abstract: The mechanical properties of the silicone rubber modified by the high oil absorption resin as the blending modifier are promoted. The tensile strength and elongation at break significantly increase. It is found that the hardness of the silicone rubber can be controlled by changing the addition of the high oil absorption resin. Besides, the oil resistance and organic solvent resistance of the modified high oil absorption resin increase. Due to the high lipophilic property and oil absorption expansion of the high oil absorption resin, the problems of the sealing failure and material damage caused by aging and corrosion deterioration of silicone rubber can be solved to increase the service life of the silicone rubber materials.
