Chlorinated rubber Chlorinated rubber, also known as chlorinated polydiene rubber, has a molecular formula [C sHe Cha] ., a relative molecular mass of 10,000 to 20,000,

Chlorinated rubber is a chlorinated natural rubber with a chlorine content of not less than 64.5%, and it is also the most important rubber derivative in the industry. It is milky white powder, tasteless, odorless, non-toxic, non-irritating to the skin, organic chlorine content 60%~70%, water content (mass fraction) <0.2%, ash content <0.15%~0.3%, iron content <0.005% , Volatile content <0.8%, non-combustible, decomposed and carbonized without melting above 200℃, combustion heat (25℃) -4958kJ/mol, thermal conductivity 0.036W/(m·K). The chlorine content is generally between 60% and 70%. Chlorinated rubber has good chemical stability, acid and alkali resistance, mineral oil and corrosive gas resistance. Dry chlorinated rubber polytetrafluoroethylene wax uses is stable at room temperature, but it becomes brittle under the sun. Adding pigments and stabilizers can greatly reduce this effect. This product is soluble in most organic solvents, such as aromatic hydrocarbons [benzene and its homologs, esters, ketones (except acetone), chlorinated hydrocarbons, glycol ethers and esters], and is insoluble in water, ethanol, and aliphatic hydrocarbons And petroleum ether and mineral oils.

The 24h water absorption rate is 0.1%~0.3%. Density (20℃) p=1.6~1.7g/cm. Viscosity: 20% solution viscosity in toluene (20℃) p=10~20Pars. The bending strength is 61.8~109.9MPa, the tensile strength is 17.7~34.3MPa, the elongation at break is 0.5%~2.2%, and the specific heat capacity is 0.47J/(g·℃). Chlorinated rubber is non-combustible, non-explosive, especially toxic. Chlorinated rubber can resist the corrosion of many chemicals, such as concentrated sulfuric acid, hydrochloric acid, 10% nitric acid, phosphoric acid, 30% hydrofluoric acid, hydrogen peroxide, calcium hypochlorite, chlorine water, chlorine gas, mineral oil, etc.; It is resistant to erosion by 20% acetic acid, citric acid, sea water, and concentrated sodium hydroxide.

The main factor affecting the performance of chlorinated rubber is its molecular weight, or the viscosity that characterizes the molecular weight. Generally, as the molecular weight or viscosity increases, the durability and gloss retention of chlorinated rubber products increase. Chlorinated rubber is mainly used as a base material (binder) and flame retardant in fire retardant coatings, which can improve the dispersion, paintability, sprayability, stability, compatibility and other properties of fire retardant coatings.
