How is chlorinated paraffin produced? What are the characteristics and uses?


Chlorinated paraffin products are light yellow viscous liquid, non-combustible, non-du, non-corrosive. Generally used in fire retardant coatings, resin plasticizers, rubber flame retardants, ink coatings and lubricating additives. They are used in cables, water pipes, flooring, artificial leather and plastic products to enhance the gloss, aging resistance and water resistance of the products.

The production process of chlorinated paraffin can be roughly divided into thermal chlorination and catalytic chlorination. The main raw materials include wax oil and liquid chlorine. Chlorine qi is heated and vaporized with steam, and then passed into a reactor to react with wax oil to prepare chlorinated paraffin. chlorination andHCLThe heat generated in the absorption process is taken away by the circulating cooling water, and the return water temperature of the circulating water is generally 75~85. In 2005, after the heat balance calculation and analysis of the production process, the original chlorine qi vaporizer and circulating water system were modified. The newly built chlorinated paraffin plant increases the heat exchange area of the vaporizer, the heat source is changed from steam to hot water, and the circulating return water is used to heat the vaporized liquid chlorine, so that the production waste heat can be used.

Note: closed operation, provide good natural ventilation conditions. Operators must be specially trained and strictly follow the operating procedures. Prevent steam leakage into the work.

Chlorinated paraffin is a chlorinated derivative of alkanes, which has the advantages of low volatility, flame retardancy, good electrical insulation and low price. Can be used as a flame retardant and PVC plasticizer. Widely used in the production of cable materials, flooring materials, hoses, artificial leather, rubber and other products. As well as applied to coatings, lubricants and other additives. Chlorinated paraffin 42 is a light yellow viscous liquid. The freezing point is -30 and the relative density is 1.16(25/25). Insoluble in water, soluble in organic solvents and various mineral oils.

Chlorinated paraffin 52 is a light yellow to yellow oily viscous liquid. The freezing point is less than -20, and the relative density (25/25) is 1.22-1.26. Soluble in benzene and ether, slightly soluble in ethanol, insoluble in water.

Chlorinated paraffin 70 is resin powder, white or light yellow, relative density is 1.65(25/4).

Application: Suitable for flame retardant of various products. Widely used in plastics, rubber, fiber and other industrial fields as a plasticizer, fabric and packaging materials surface treatment agent, adhesive materials and coatings modifier, high pressure lubrication and metal cutting wear-resistant agent, fungicide, waterproofing agent, ink additives. Put it in the air. Avoid contact with oxidizing agents and bases. Handle with care to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. Empty containers may leave harmful substances.
