Problems solved by technology

After grafting, the carbon-forming performance of the fabric is enhanced, and the flame-retardant performance is improved, but the preparation process is complicated and the grafting rate is low
[0004] Li Xiang et al. in "Research on the Application of Multifunctional Phosphate Ethylenediamine Salt Flame Retardants on Nylon Fabrics" (Li Xiang, Ding Bin, Hao Fengling, et al. Printing and Dyeing Auxiliaries, 2015(1):45-48) Using bistrimethylolpropane, phosphorus oxychloride and ethylenediamine as raw materials, a multifunctional flame retardant bistrimethylolpropane phosphate ethylenediamine salt was synthesized, and nylon fabric was treated with it. The results showed that after finishing The fabric flame retardant effect is obvious, but this kind of flame retardant has the disadvantages of complicated preparation process and high fabric treatment temperature
[0005] It can be seen from the above that most flame retardant fabrics have good flame retardant properties after being modified with flame retardants, but the process of preparing flame retardant fabrics with flame retardants is complicated, contains halogen or the fabric treatment temperature is too high, which is harmful to the environment. It is harmful and consumes a lot of energy, so it is not suitable for industrial application

Abstract

The invention discloses a halogen-free flame-retardant fiber cloth derived from alginic acid and a preparation method thereof, and relates to the technical field of flame-retardant fabrics. A halogen-free flame-retardant fiber cloth of alginic acid derivatives, including alginic acid derivatives, a halogen-free flame retardant, and fiber cloth. The alginic acid derivatives are self-polymerizing flexible macromolecules of phosphorus and silicon alginate. During the impregnation process of the fiber cloth, the alginic acid derivatives are adsorbed on the surface of the fiber cloth, and the exposed silicon hydroxyl groups will undergo esterification reaction with the alginic acid derivatives during the post-heating process, and the silicon hydroxyl groups will dehydrate and self-condense to achieve macromolecules, thus forming A cross-linked flexible polymer flame retardant film is coated on the surface of the fabric fiber to obtain a semi-permanent flame-retardant fiber cloth. The halogen-free flame retardant further increases the flame-retardant performance of the fiber cloth. This flame-retardant fiber cloth Excellent flame retardancy and no dripping.

Description

Technical field [0001] The present invention relates to the field of flame retardant fabric, and more particularly to a sealinic acid derivative halogen-free flame retardant fiber cloth and a preparation method thereof. Background technique [0002] Fiber fabrics have a wide range of applications in daily life, military, architecture, biology, medicine. However, since the unreated fiber cloth usually has flammable characteristics, it is easy to cause fire, bringing huge economic losses and casualties. Given the textile better flame retardancy has become an inevitable trend of development, and countries have gradually introduced the law and put forward corresponding flame retardant performance requirements for textile flame retardation. [0003] Duan Yuszhe, Zhang Sheng is in the "Flame Retardance of Microwave Grafting Modified Nylon 66 Fabrics" (Beijing Chemical Technology, Natural Science Edition, 2016, 43 (2): 19-26), a microwave graf Modified method, this method is to graf the...
