Flame retardants for environmentally friendly flame retardant fabrics
Classification:
flame retardant fabric
Flame-retardant finishing of textiles is becoming more and more important, but flame retardants commonly used in the market such as tris(aziridyl)phosphorus oxide (i.e. AP0), tris( 2,3-Dibromopropyl)phosphate (i.e. TDBPP), tetrahydroxymethylphosphorus chloride (i.e. THPC), polybrominated biphenyl, decabromobiphenyl Ethers, etc. are harmful to the human body and can pollute the environmente. Take tetrahydroxymethylphosphorus chloride as an example. It is aFlame retardantIt is a commonly used flame retardant with good effect and excellent wash resistance. However, in recent yearsit has been found that it The lower bond energy of the P-C bond will decompose to produce formaldehyde. This formaldehyde may also react with hydrogen chloride to form carcinogenic dichloromethyl ether, so it is banned from the market. The environmentally friendly flame retardants currently available on the market include flame retardant FR45, which is a non-durable flame retardant made of ammonium polyphosphate. The composition and application process are simple and no baking is required.
Zirconium-based flame retardants and niobium-based flame retardants are composed of metal complexes of titanium fluoride or zirconium fluoride (i.e. K2TiF6 or K2ZrF6) respectively. When used, only It needs to be treated at 60℃ for half an hour to chemically react with the interior of the wool fiber to obtain a flame retardant effect. It does not affect the feel of the wool and has certain washabilitySex, my country’s product is called flame retardant WFR-866F. In addition, some new safe flame retardants have also been developed abroad, and Otaval has entered the market.
