摘　　要：以橡胶密封膜用单层布的骨架粘接性、胶料耐油性以及胶布经、纬向力学强度等指标为主要考察依据,对单层布的胶料主体材质、粘合体系、硫化体系以及骨架材料进行了对比选择。结果表明,胶料主体材料选用NBR/PVC=70/30,粘合体系选用白炭黑,硫化体系选用高促低硫体系并配合表面进行RFL浸胶处理的纬向加强型NN250帆布,胶布的骨架粘和性、胶料耐油性综合性最优,同时胶布经、纬向力学强度完全满足3.5 kN/3 cm以上的要求,可以作为石化密封膜胶布使用。This paper mainly studied skeleton adhesive,rubber oil resistance and strength of tape in the weft and radial direction compared and selected,body materiais adhesive system,curing system and reinforcing materials. The results showed that the NBR / PVC = 70 /30 is chosen as the main material,the silica is chosen as adhesive system,vulcanization system with high and low sulfur system with RFL surface dipping treatment of zonal enhanced NN250 canvas,fabric,glue stick and skeleton oil resistance comprehensive optimum,and the strength of tape in the weft and radial direction of the gas holder tape could fully satisfy the requirements of more than 3. 5 kN /3m. and can be used as a petrochemical sealing film tape.
