Class of flame retardants
The classification of flame retardants can be divided into inorganic flame retardant, organic flame retardant and organic/inorganic mixed flame retardant. At present, the most used is inorganic flame retardant. The main products are aluminum hydroxide, magnesium hydroxide, monoammonium phosphate, diammonium phosphate, ammonium chloride and boric acid. The main products of organic flame retardant are halogen, phosphate and halogenated phosphate.
Some organic flame retardant used for the durable flame retardant finishing of textile fabric, such as containing six bromine flame retardant is added in the coating agent of water dispersion system, ten bromine - antimony trioxide flame retardant system, flame retardant properties of washing resistance; Organic/inorganic mixed flame retardant is an improved product of inorganic salt flame retardant. It is mainly used in water emulsion of non-water-soluble organic phosphate ester to replace the inorganic flame retardant. In the above three kinds of flame retardants and inorganic flame retardants nontoxic and harmless, smoke-free, no halogen, widely applied in various fields, accounting for more than 1/2 total flame retardants requirements demand, growth rates have increased.
The classification of flame retardants is different according to the method of use, which can be divided into additive flame retardant and reactive flame retardant. Mainly by adding flame retardant agent is added in the fuel play a role of flame retardant, flame retardant reactive flame retardants in introducing flame retardant polymer materials through chemical reaction, so as to improve the flame resistance of materials, to prevent the material from being the purpose of the ignition and flame spread restraint. Additive type flame retardants are dominant (about 85% of flame retardants, only 15% of reactive flame retardants), and the range is wide.
The category of flame retardant is classified according to the durability of flame retardant properties. Non-durable flame retardants: also known as temporary flame retardants, most of them are water-soluble (or emulsions) of inorganic salts. The flame retardants are dissolved in water and the fabric is soaked and dried to be used. In the second bath, the second bath USES ammonia or soda to deposit the metal oxide on the fabric. The method is simple and the price is low, but the fabric feels bad, and the flame retardant effect is greatly reduced after washing. Half the durability of flame retardants: its flame retardant product ability 1 ￣ gentle washing 10 times, but not resistant to high temperature soaping. The method is a mixture of urea-phosphoric acid (commonly known as ban-flam), urea-formaldehyde, ammonium phosphate, and ammonium chloride.
Tris(2-chloroisopropyl)Phosphate(TCPP)
The product is used for the soft / hard polyurethane foam, with thermal and hydrolytic stability good, especially suitable for ASTME84 (Level 11) foam, with low viscosity unsaturated polyester resin in low temperature application and phenolic plastics at. This product is also used to grab the foam sealant and sheet production. For polyvinyl chloride, polystyrene, phenolic resin, acrylic resin and rubber, coating, flame retardant, also used for soft and hard polyurethane foam, epoxy resin, polystyrene, cellulose acetate, ethyl cellulose tree and phenolic plastics, polyvinyl acetate and gun type foam sealant production. Particularly recommended for rigid polyurethane foam has excellent thermal and hydrolytic stability is particularly suitable for ASTM84 (II), compound for polyurethane foam and unsaturated resin and phenolic plastics.
Due to the transport process to avoid collision damage, Tris2-chloropropyl phosphate TCPP packaging methods generally used 250KG galvanized iron drum.
Below to introduce some of Tris2-chloropropyl phosphate TCPP packaging:
Net weight 250KG/ galvanized iron drum (a small cabinet pallet loaded 20 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).
Company 1.5 hour drive from Shanghai, the general sent to Shanghai port, the goods from customs inspection to the fastest one week after, the slowest ten days.
In view of the domestic and foreign demand is relatively small clients, also can use 50KG plastic bucket.
If you have special requirements on the Tris2-chloropropyl phosphate TCPP packaging, please contact us, try to meet the packaging requirements of customers.
Durability flame retardant: chemical method is used to polymerize or condensation reaction on the surface of the fiber, forming an insoluble polymer, generally requiring more than 30 times. The law mainly includes the huntsman and Proban methods.
CP method is easy to implement, and the flame retardant effect is significant. The disadvantage is that the fabric has a great loss of strength and has great influence on apparel performance. Proban is used to clean the flame retardant effect of the fabric, especially the hand feeling and strength, but the danger is greater, the environmental pollution is severe, and the promotion is limited.
The characteristics of flame retardants. At present, the main flame retardants are organic halide, organophosphorus and inorganic. Organic bromine flame retardants in the phosphorus-containing flame retardant with wider range of use, the main characteristic is high flame retardant efficiency, less consumption, and small impact on material performance, but in the pyrolysis and combustion generated when a lot of smoke and corrosive gas. Organic phosphorus flame retardants effectively overcomes the drawback of containing halogen flame retardant, has the function of flame retardant, insulation, oxygen, and smoke less, not easy to form a toxic and corrosive gas, etc., to adapt to the requirements of environmental protection. The biggest advantage of inorganic flame retardants is low toxicity, low smoke or smoke suppression, low corrosion and low price, but because of the large amount of addition, the application of them is limited.
According to the combustion characteristics of combustible materials, the flame retardant technology is used to convert the combustible materials to reduce the burning speed and prevent the fire from expanding. Both inorganic flame retardants and organic flame retardants have some disadvantages: (1) release poisonous gases and produce smoke; (2) corrosive substances; (3) large amount of addition, affecting mechanical properties; (4) there is certain pollution to the environment. Therefore, in the light of the shortage of flame retardants, the development of low-toxicity, low-smoke, harmless and efficient anti-smoking flame retardants has become a development trend.
After the so-called "fire", is not flame retardant finishing of textiles in contact with fire will not burn when the source, but to make the fabric in the fire can minimize its flammability, slow speed, not form a large area burn, left after the fire, can quickly self-extinguishing, no longer continue to burn or smoldering. The flame retardant is used to meet the flame retardancy of textiles by absorbing heat, covering, inhibiting chain reaction, and choking of gas.
