Abstract

The invention belongs to the field of preparation of modified silicone oil, and relates to a flame-retardant modified silicone oil, a preparation method thereof, and an application thereof in textileproduction. The modified silicone oil is mainly prepared through a copolymerization reaction of (perbromo-1,2-phenylene)dimethanol, trimethylol melamine resin, 1,4-dibromo-2,3-butylene glycol, hexaethylcyclotrisiloxane, methyldichlorosilane, 3-aminopropylsilane triol, ethylenediamine tetramethylenephosphonic acid and 1,3-bis(trimethylsilyl)urea. Monomers with high content of flame-retardant elements, such as bromine, nitrogen and phosphorus, comprising (perbromo-1,2-phenylene)dimethanol, trimethylol melamine resin, 1,4-dibromo-2,3-butylene glycol and ethylenediamine tetramethylenephosphonic acid are used as main copolymerization raw materials, and are copolymerized with an organosiloxane raw material to obtain the modified silicone oil. The obtained modified silicone oil has an excellent flexible performance, also has an excellent flame retardant performance due to the high content of the flame retardant elements comprising bromine, nitrogen and phosphorus, can be applied to textiles of machine-made bleached twill pure cotton clothes, and has an oxygen index reaching 32% or above.

Description

technical field [0001] The invention belongs to the field of preparation of modified silicone oil, and in particular relates to a flame-retardant modified silicone oil, and also relates to a preparation method of the above-mentioned silicone oil and its application in textile production. Background technique [0002] Although ordinary silicone oil is not flammable, when it is used as a softener on textiles, it cannot effectively prevent the burning of cotton and various fiber textiles. The oxygen index of textiles using ordinary silicone oil as a softener is still low, and the flammability Strong, flammable, and a great safety hazard; in order to reduce its flammability and improve safety, it is necessary to use truly flame-retardant silicone oil to further increase the oxygen index of textiles while ensuring softness. [0003] CN104628990A discloses a slip elastic silicone oil for textiles, a preparation method and an application thereof. The method is to add isophorone di...
