example 1

[0022] Weigh 55-60g of diatomite, grind it for 9 minutes, pass it through a 120-mesh sieve, collect the sieved powder, pour the sieved powder into 15mL of 3mol / L sodium hydroxide solution and 8mL of 2mol / L partial silicon Mix and stir for 1 hour at a temperature of 70°C in a mixer of sodium acid solution to obtain an activated sol; mix peanut oil, diethanolamine, and sodium ethylate in a reaction kettle at a mass ratio of 5:2:1, and place them in a reaction vessel at a temperature of 115°C. Stir and react for 32 minutes under nitrogen protection to obtain the amino product. Mix sodium alginate and absolute ethanol with a mass ratio of 5:1 and stir for 27 minutes to obtain a self-made suspension. Mix the amino product with deionized water at a mass ratio of 3:1 Mix and stir for 15 minutes to obtain an aqueous solution of ammonia, then mix the aqueous solution of ammonia and the self-made suspension at a volume ratio of 1:3, and stir and react for 3 hours at room temperature with...

Abstract

The invention relates to the technical field of textile, in particular to a high-temperature-resistant flame-retardant fiber for preparing a firefighter uniform and a preparation process of the fiber.According to the fiber, since sodium hydroxide not only has strong alkalinity but also has a high ionization speed and a high hydration degree, the sodium hydroxide can react with -Si-OH with reaction activity in diatomite to form silicon-oxygen tetrahedron ions -Si-O-Na<+> and further react to form a siliceous layer with a spatial netlike structure; the siliceous layer can effectively isolate heat and prevent oxygen from making contact with inflammable substances; and under the synergistic effect of sodium metasilicate, generated silicic acid and a -O-Si-O-Si-chain are subjected to a polycondensation reaction to form an interlaced and interpenetrating spatial netlike structure. Therefore, the flame retardation of the high-temperature-resistant flame-retardant fiber for preparing the firefighter uniform is remarkably improved, and the fiber has broad application scenes.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a high-temperature-resistant and flame-retardant fiber used for preparing fire-fighting clothing and a preparation process thereof. Background technique [0002] Firefighting clothing is one of the important equipment to protect the personal safety of firefighters who are active on the front line of firefighting. It is not only an indispensable item in the fire rescue scene, but also a fireproof appliance to protect firefighters from injury. [0003] When a fire breaks out, firefighters are the first-line people to go to the fire scene to rescue, so the safety of firefighters has been paid attention to, so the industry has developed a kind of firefighting clothing made of fireproof materials, so that firefighters can pass through the firefighting clothing itself. It has fireproof properties to protect yourself from the heat and fire burns generated in the fire scene. However, b...
