1.properties and Usage
Chlorinated rubber is made from natural rubber or synthetic rubber by chlorination, it enjoys many unique properties, which are antifriction, resistance to corrosion, quickly drying, and excellent conglutination, anti-water penetration, as well as fire retarder .The main factor to affect property of chlorinated rubber is its molecular weight or its viscidity to character molecular weight .On the whole, with increase of its viscidity, its service durability and gloss retentively rise ;but, as paint, its properties easy to disperse, to brush, to spray and its compatibility as well as its solvent precipitation all decrease .
Being divided into the varied models according to its molecular weight or the value of its viscidity .Chlorinated rubber is mainly used in fields of printing ink .paint and gluing agent, etc .Ronghly, the lower viscidity (<10cp) is used as the additive of printing ink ;the middle (10~30cp) is used to make (100~300cp) is used to make gluing agent .The condition of its application at home and abroad indicates that the product with middle viscidity is widely used in paint .In aspect of paint, roadsign coating, shipping coating, container coating .building coating, swimming pool coating and flame retardant coating are the main fields of chlorinated rubber’s application .

3.The process route of aqueous phased method
Comparing with the traditional technology of solvent method, the aqueous phased method developed by our Academy has the following obvious advantages:
1) The process of aqueous phased method is simple, also leave out the steps of solvent recovery and dry as well as its relation equipments .
2) The coat of production is cower, because of omitting a great amount of material-CCl4 in aqueous phased process .
3) The aqueous phased process eliminates the environmental pollution of CCl4, improves the environment of productive operation, and protects the health of workers, at the same time, omits the waste water treatment of CCl4 as well as the relative equipments .
4) Comparing with the solvent method, the aqueous phased method would require less investment in equipments, equal to about 2/3 of investment of the solvent method.
5) The consumption of energy is lower during aqueous phased process .
6) Chlorinated rubber products made by aqueous phased method are superior to the ones made by solvent method in its many properties.
4.Main Equipments
enamel reactor, system-equipments through which chlorine gas would go, press filter, dryer, freezer and other equipments.
5.Consumption quota of main raw materials
natural emulsion - - - - -0.72t/t
liquid chlorine - - - - - 1.5t/t
6.Enrironmental protection
three-waste treatment
Dilute hydrochloric acid in this process can be used by circulation. After washing, the diluted acid is neutralized by lime ,then is drained off after reaching the standard of discharge.
