| 中文摘要: |
| 简介防爆安检用地井井盖橡胶封条的研制。防爆安检用地井井盖橡胶封条呈近似正方形（边长约72 mm）形状，由橡胶面层、橡胶粘合层和防粘层组成。橡胶面层有由两组并行排列的不连续弧形镂刻花纹组成的预裂口，正面印有警示标识及计算机识别编码。橡胶面层胶和橡胶粘合层胶主体材料分别采用三元乙丙橡胶和丁基橡胶。防爆安检用地井井盖橡胶封条已广泛应用。 |
| 英文摘要: |
| This paper introduced the development of rubber seal of the well cover for explosion-proof safety-check.The seal was in square shape with a length of about 72 mm and consisted of a rubber surface layer，a rubber adhesive layer and an anti-stick layer.The rubber surface layer had a pre-crack composed of two sets of discontinuous curved engraved patterns arranged in parallel，with a warning mark and a computer identification code printed on the front side.The matrix materials for rubber surface layer and rubber adhesive layer were ethylene-propylene-diene rubber and butyl rubber，respectively.This rubber seal of well cover for explosion-proof safety-check has been widely used. |
