Problems solved by technology

[0011] Organophosphorus flame retardant: THPC (the flame retardancy is improved, but the mechanical properties are reduced and the handle is rough, and there is a phenomenon of chlorine absorption and yellowing); PyrovatexCP (generally does not work on polyester, so the flame retardant finishing of polyester / cotton blended fabrics must Select appropriate finishing agents according to fiber characteristics), develop a new type of flame retardant finishing agent, which has a high market prospect

Abstract

The invention discloses a flame-retarding finishing agent based on diaminostilbene / benzotriazole. The flame-retarding finishing agent is prepared from the following components in parts by weight: 12 to 15 parts of diaminostilbene, 1 to 1.5 parts of benzotriazole and 20 to 25 parts of glycerin; a preparation method of the flame-retarding finishing agent comprises: adding an ethanol solution into the glycerin and uniformly stirring at high temperature; then dropwise adding the benzotriazole; rapidly cooling mixed liquid to room temperature and then adding the diaminostilbene and uniformly mixing. The flame-retarding finishing agent provided by the invention is applied to a post-finishing process of cotton and polyester fabrics, has a good and lasting flame-retarding property, does not generate toxic gas in a combustion process and has good compatibility with a dyestuff and other auxiliary agents; the flame-retarding finishing agent is applicable to conventional post-finishing equipment, basically has no influences on mechanical properties and hand feeling of the finished fabrics, is safe to human bodies and environment and is a relatively ideal novel flame-retarding finishing agent.

Description

[0001] Technical field: [0002] The invention relates to the chemical field of textile auxiliaries, in particular to a flame retardant finishing agent based on diaminostilbene / benzotriazole. [0003] Background technique: [0004] Flame-retardant finishing means that the finished fabrics have different degrees of ability to prevent the spread of flames, and can quickly stop burning after leaving the fire source. [0005] There are three ways of flame retardant finishing: [0006] (1) Exhaustion method: The flame retardant is combined with cellulose by ionic or covalent bonds, making it insoluble in cellulose to obtain a durable flame retardant effect. [0007] (2) Stock solution method: add the flame retardant directly into the spinning solution. [0008] (3) Copolymerization method: flame retardant is added to the polymer chain segment, so that the fabric has acceptable fastness to washing, bleaching, perspiration, etc., and will not be absorbed by the skin.
