In traditional chlorinated rubber, the rubber is chlorinated in CC14 and then precipitated in water. The finished product often contains a lot of carbon tetrachloride, which pollutes the atmosphere and is currently restricted . my country joined the "Montreal Protocol on Substances that Deplete the Ozone Layer" for the protection of the ozone layer in 1991. According to the revised "Montreal Protocol", my country promised to make a commitment to the world to gradually phase out the production and consumption of ozone-depleting substances, gradually stop and limit in Carbon tetrachloride is used in the production of chlorinated rubber, and the use of carbon tetrachloride should be completely stopped by 2010. Developed countries have shut down the production of chlorinated rubber with carbon tetrachloride since 1995, and replaced chlorinated rubber with high-chlorinated polyethylene, high-chlorinated polypropylene, acrylic resin, etc., or used aqueous phase suspension method, non-chlorinated rubber New technologies such as carbon tetrachloride solvent method replace the original production process.
Water phase chlorinated rubber, the chlorination process is carried out in the water phase, no organic solvent is used at all. Water phase chlorinated rubber is a high hardness, powdery thermoplastic resin with a chlorine content of 65%, which has excellent weather resistance, adhesion, chemical stability, salt water resistance and UV protection.
