The formula and preparation method of chlorobutyl rubber stopper belong to the technical field of medical rubber accessories. The method can use a small amount of white carbon black on the premise of selecting a suitable vulcanization system on the premise of not adding activators, accelerators and other chemical additives. The method of replacing the same amount of clay to improve the compatibility of chlorobutyl rubber stopper and medicines. The silica used in the formula of the present invention is precipitated hydrated silica, which can improve the performance of the rubber without reducing the fluidity of the rubber. Vulcanization temperature, through high-temperature vulcanization, more water and small molecular substances in the rubber compound are precipitated, and the moisture and small molecular substances contained in the chlorobutyl rubber stopper are reduced to improve the compatibility of chlorobutyl rubber stopper with medicines, so as to meet the needs of medicines. The factory has higher requirements.
The above is a brief introduction to the knowledge about the formula and preparation method of chlorobutyl rubber stopper.
