Problems solved by technology

After the 1960s, with the formulation of fire protection regulations in many countries, flame retardant technology has been widely used in textiles, but mainly involves halogen and phosphorus organic compound flame retardants, such as Lenging (Austria), Polynosic (Japan) HFG (Japan), although these fibers containing organic compound flame retardants have good flame retardant effect, they are not friendly to the environment or will release a lot of poisonous gas and smoke when burned, which has safety and environmental problems
[0004] However, these salt flame retardants are not coated, which can easily cause accelerated aging of the viscose collagen solution, a sharp increase in viscosity, and cannot be spun due to gelation, or cannot form effective cross-linking and fixation. Loss of flame retardant effect during use

Embodiment 1

[0039] An environment-friendly flame retardant, the raw materials of the flame retardant include organosilane hydrolysis dispersion and fixed crosslinking agent.

[0040] The chemical formula of the organosilane hydrolysis dispersion is:

[0041] [Me 2 O n SiO 2 ] + [--CONH]

[0042] Among them: Me represents metal ion; SiO 2 The content is 9.23~53%; the amide content is 4.3~27%; the metal ion is Li + 、K + 、Na + .

[0043] Further, the raw materials of the fixed crosslinking agent include polyhydroxy carboxylic acid, polyhydric alcohol, sugar and metal components; the polyhydroxy carboxylic acid is one of lactic acid, tartaric acid, citric acid or β-hydroxybutyric acid or a mixture of several; the polyhydric alcohol is one or a mixture of propylene glycol, glycerol, ethylene glycol or polyhydric sterols; the sugar is one or several of sucrose, fructose or glucose a mixture of species; the metal component is one or a mixture of titanium tetrachloride, calcium chloride, ...

Embodiment 2

[0063] This embodiment is another preferred solution based on the embodiment 1, and the parts that are the same as those in the embodiment 1 will not be repeated here.

[0064] The organosilane hydrolysis dispersion is made of industrial silane and acetamide, and the industrial silane, acetamide and water are mixed in a ratio of 75:8:12, preferably heated to 45°C, stirred for 2 hours, and filtered The finished product after the machine is the flame retardant organosilane hydrolysis dispersion;

[0065] The raw materials of the fixed crosslinking agent include lactic acid, tetraisopropanol titanate, ammonia and sucrose, and the ratio of parts by weight of each raw material is:

[0066] Lactic acid 12

[0067] Tetraisopropoxy titanate 38

[0068] Ammonia 30~60

[0069] Sucrose 3

[0070] water 30;

[0071] Mix lactic acid and water according to the above ratio, raise the temperature to 85°C, start stirring, slowly add the tetraisopropanol titanate and sucrose, keep warm for...

Abstract

The invention discloses an environment-friendly type fire retardant as well as a preparation method and an application thereof. The fire retardant adopts a preparation method for an environment-friendly type fire retardant matched product, which takes organic silicon hydrolyzing dispersion liquid as a main component of the fire retardant and takes a fixed cross-linking agent as a post-treatment component. The other aim of the invention is to develop the application of the environment-friendly type fire retardant in spinning and post-treat of inflaming retarding viscoses and inflaming retarding synthetic fibers. Raw materials for preparing the environment-friendly type fire retardant are wide in source and low in price; the adverse effects on the environment and the safety, caused by traditional halogen-based and phosphorus based flame retardants, are overcome; the social benefits and the economic benefits are very great.

Description

technical field [0001] The invention belongs to the field of chemical fiber processing, and in particular relates to an environment-friendly flame retardant and its preparation method and application. Background technique [0002] Flame retardant science and technology is a science developed by human beings in order to meet the needs of social development, prevent and control fires, and protect human property safety. scientific method. Flame retardant technology converts combustible materials into flame-retardant or non-combustible materials according to the combustion characteristics of combustible materials, reduces the burning speed of substances, and prevents fire from expanding. [0003] With the development of social material civilization, people pay more and more attention to flame retardant technology. As early as 1785, the British used a mixture of alum, borax and ferrous sulfate to make cellulose textiles and pulp flame retardant. In 1913, dye scientist Parkin pr...
