Abstract

The invention discloses a preparation method and an application of an epoxy-terminated brominated polyether fabric flame-retardation finishing agent. A mass part ratio of epoxy-terminated brominated polyether to epoxy chloropropane to a catalyst to an initiator to a solvent is 20-30:10-20:0.1-5:0.1-10:45-60; or a mass part ratio of epoxy-terminated brominated polyether to epoxy chloropropane to the catalyst to a curing agent to the solvent is 15-25:10-15:0.1-5:20-50:38-50. The method is simple and convenient; the prepared flame-retardation finishing agent has a high content of bromine, and a permanent and excellent flame retardation effect; and a finished fabric does not contain free bromides, a polyether structure is firmly combined with the fabric, and an epoxy structure is firmly combined with a highly-polar fiber fabric, so the fabric is washable.

Description

technical field [0001] The invention belongs to the field of flame-retardant finishing of fabrics, and in particular relates to a preparation method and application of a flame-retardant finishing agent for epoxy-terminated brominated polyether textiles, which is suitable for fabrics such as cotton, hemp, and high-polarity synthetic fibers. Background technique [0002] With the continuous improvement of people's living standards, the demand and types of textiles for decoration and clothing are increasing day by day, and the problem of causing disasters due to the ignition of textiles is also becoming more and more serious. The combustion of fabrics will produce harmful gases such as carbon monoxide, carbon dioxide, cyanide, and nitrogen oxides, which will cause great harm to the human body. Therefore, people have higher and higher requirements for the flame retardancy of fabrics. [0003] The main methods of flame retardant fabrics are: (1) prepare flame retardant fabric f...
