Chlorinated paraffin-42 is a kind of flame retardant, no explosion hazard, spontaneous ignition point 357℃, is one of halogen flame retardants. Because chlorinated paraffin has a similar structure to polyvinyl chloride, it has good flame retardancy and electrical insulation, and low volatility, so it is commonly used as a plasticizing flame retardant for PVC cables, hoses, plates, artificial leather, and films. Chlorinated paraffin can be used as styrene-butadiene rubber, nitrile rubber, chloroprene rubber, polyurethane resin, etc. to prepare fireproof coatings. It can act as a flame retardant and plasticizer. It can also be used on the surface of fabrics, wood, paper and other materials. Flame retardant treatment to reduce its flammability.
(13) Chlorinated paraffin-50 Chlorinated paraffin-50, also known as chlorinated wax-50, chlorinated petroleum-50, molecular formula Crs Hz sCl, relative molecular weight 420, is a light yellow clear viscous liquid, odorless, non-toxic, insoluble in water , Slightly soluble in alcohol, easily soluble in benzene and ether. Density (25℃) 1.235~1.255g/cm, viscosity (25℃) 12~16Pa·s, refractive index (20℃) 1.505~1.515, freezing point below 30℃, specific heat capacity 1.34J/g, chlorine content 50% ~54%, acid value ≤0.71mgKOH/g, thermal decomposition temperature ≥120℃, heating over 150℃ or adding alkali and alcohol solution to azeotrope can remove hydrogen chloride to generate higher alkenes; chlorinated paraffin and water will exceed the temperature The hydrolysis reaction started at 150°C.
Chlorinated paraffins and other products (except chlorohydrocarbon-13) are resistant to acids, alkalis and saline solutions. It is relatively easy to dissolve in mineral oils, lubricating oils, organic chlorine solvents, ethers, esters, cyclohexanol, castor oil and other vegetable oils. They can be compatible with natural rubber, chlorinated rubber, synthetic rubber, polyester resin and alkyd resins.
Chlorinated Paraffin-50 not only has a flame retardant effect, but also has a plasticizing effect, polyamide wax uses so it has become the most important plasticizer. It is a substitute for dibutyl phthalate, dioctyl phthalate, and tricresyl phosphate Or auxiliary additives, usually the content of this product in the plasticizing mixture can reach 30% to 50% of the total plasticizer. Chlorocarbon-50 also has an anti-aging effect. The fire-resistant and flame-retardant liquid formulated on the basis of this product can treat the surface of flammable fiber materials such as fabrics, paper, canvas, etc. to have fire resistance and weather resistance, enhance anti-aging properties, and reduce the main plasticizer Fugacity reduces the odor and improves the mechanical strength and durability of the product. Chlorocarbon-50 is used in fire-retardant coatings and fire-retardant liquids, mainly acting as a flame retardant, plasticizer and anti-aging agent.
