Embodiment 1
[0030] Take the production method of the high-strength self-adhesive rubber composite waterproof hanging pavement coil used in the waterproof project of the underground railway as an example
[0031] I. Preparation of Non-Vulcanized Rubber Sheets
[0032] ingredients
[0033] Based on synthetic rubber, prepare raw materials according to the following weight ratio
[0034] Synthetic Rubber - Butyl Rubber 100
[0035] Tackifier - Polyisobutylene 10
