Flame retardant plasticizer---chlorinated paraffin-70
In China's plasticizer industry, chlorinated paraffin is the second largest plasticizer after DOP. At present, chlorine-based flame retardant plasticizers are developing toward non-polluting, high-purity, high-heat stability and high content. The representative product is chlorinated paraffin-70. With the plastic to replace the wood. With the development of plastic-made steel and the establishment of various flame-retardant regulations, the improvement of stricter and more stringent implementation regulations, and the emphasis on the flame-retardant properties of PVC plastic doors and windows, interior decorative PVC slabs, wallpapers, drop pipes, etc. A large potential field has been formed. After more than 30 years of application development abroad, chlorinated paraffin-70 has been used in all general-purpose plastic products. With the development of the plastics industry, the demand for plastic products, plastic pipes, agricultural films, decorative materials, etc. is strong. The chlorocarbon 70 is favored by users, which shows that the purchase and sale are booming.
Chlorinated paraffin-70 can make soft PVC have cheap and efficient flame retardant effect by using appropriate formula, especially suitable for automobile decoration, diving suit wall coating and so on. It is growing fast. Chlorinated paraffin-70 has good plasticizing effect and the best combination of sufficient compatibility with PVC and suitable viscosity, and increases the flame retardant performance and tolerance to inorganic additives and pigments. Selects the flame retardant effect of oxidized paraffin. Related to the amount of chlorine, for amorphous polymers. The higher the chlorine content. The better the compatibility, and the chlorinated paraffin should be used as much as possible. To reduce the amount of flammable plasticizer used in DOP. For high polymers such as polyethylene, chlorinated paraffin-70 should also be used. Chlorinated paraffin-70 has little thermal decomposition at most processing temperatures. As an organic chlorine-based flame retardant, the product is chemically inert and has excellent acid and alkali corrosion resistance, which makes it widely used in ABS, PVC, unsaturated polyester plastics, natural and synthetic rubber. Especially in PVC and rubber for coal transportation belts, chlorinated paraffin has excellent flame retardancy and electrical properties. Insulation and sheathing below l4 volts in cable formulations for use in PVC wire formulations at 105 °C. Product quality can be guaranteed and production costs can be reduced.
With the increase in the use of plastic products in construction, packaging, transportation, electrical and electronic, furniture, clothing, etc., its development prospects are broad. At l998. Although PVC sales are not smooth, chlorinated paraffins are still selling well. In the electrical and electronics industry. In 1977, the United States had already prevented the burning of TV sets and radios. The UL standard rhyme UL492 management regulations were formulated, and different flame retardant standards and corresponding regulations were formulated for non-returnable plastics, such as FAA regulations, automotive Mrss-NO302 specifications, and electrical appliances. EMA, etc. Since chlorinated paraffin has good thermal stability, it can be used for electrical and electronic applications. In oxidized paraffin. Chlorine wax. -42 can reduce the flame retardancy of rubber and plastic. And the volatility is low, the aging speed is slow, but its compatibility is poor. Large viscosity and dark color. Chlorinated paraffin has been widely used in cable materials, flooring, water pipes, films, artificial leather, etc. It is also used in rubber products and rubber-based surface coatings and heavy fabrics such as cloth, raincoat and coal-fired layer formulations. Chloroquinone has good compatibility with PVC. Can reduce the cost rhyme by 10%.
Chloro-wax-70 has a large compressive strength to achieve good flame retardancy and promote emulsification. Can be non-slip and lubricated, and toughened. Viscosity and anti-radiation effect, other flame retardants such as antimony trioxide in combination with chlorinated paraffin, hydrogen fluoride released during combustion has a strong composite synergistic flame retardant effect. After adding modified materials such as improved fluidity and thermal stability, chlorinated paraffin can overcome the fatal weakness of petroleum series products, and can also solve the problem of discoloration of products caused by poor stability of chlorinated paraffin. This plasticizer is compatible with PVC, has strong plasticity, light color and non-combustible. Non-toxic, odorless, low volatility, can be used to replace 20% - 30% of DOP or DBP, can improve the tensile strength of the foam sheet, elongation at break
