Problems solved by technology

At the same time, the use of N-methylolated resin will inevitably release formaldehyde and cause environmental problems, and expensive butane tetracarboxylic acid in turn restricts the use of this type of flame retardant

Embodiment 1

[0049] In a 2-liter four-necked round-bottomed flask equipped with a stirrer, a thermometer, a dropping funnel and a condenser tube, add 300 g (2.42 mol) of dimethyl methylphosphonate, heat to 60-65 ° C, and then add pentoxide 300 g (2.12 mol) of diphosphorus, heat up to 115-120° C. after the complete dissolution of the diphosphorus pentoxide, and keep it warm for 1 hour. Cool the reactant to 60-65°C, add 24 grams (0.52mol) of ethanol, and add 3-glycidyl etheroxypropyltrimethoxysilane (SCA-403, Zhangjiagang Guotai Huarong Chemical New Co., Ltd. Material Co., Ltd.) 572 g (2.42 mol), and finally add 0.6 g of stannous octoate, and react at 100-105° C. for 1 hour to obtain a colorless transparent viscous liquid. Distill the viscous liquid at about 100°C and vacuum degree of -0.095~-0.098Mpa to remove unreacted raw materials, and the transparent viscous liquid left at the bottom of the bottle is the refined product of the flame retardant. After measurement, the viscosity average m...

Embodiment 2

[0057] In a 2-liter four-necked round-bottomed flask equipped with a stirrer, a thermometer, a dropping funnel and a condenser tube, add 431 grams (2.42 mol) of allyl phosphonic acid diethyl ester, heat to 30-35 ° C, and then add 150 grams (1.06 mol) of phosphorus pentoxide, after the phosphorus pentoxide is completely dissolved, heat up to 75-80°C, and keep it warm for 8 hours. Cool the reactant to 60-65°C, add 24 grams (0.52mol) of ethanol, and add 3-glycidyl etheroxypropyl triethoxysilane (SCA-413, Zhangjiagang Guotai Huarong Chemical Industry Co., Ltd. New Materials Co., Ltd.) 320 g (1.15 mol), and finally add 4.2 g of sodium ethylate, and keep warm at 70-75 ° C for 6 hours to obtain a colorless transparent viscous liquid. Distill the unreacted raw materials under reduced pressure at about 100°C and vacuum degree of -0.095~-0.098Mpa, and the transparent viscous liquid left at the bottom of the bottle is the prepared flame retardant Refined products. After measurement, th...

Abstract

The invention discloses an environmentally friendly fabric fire retardant and its preparation method and use. The environmentally friendly fabric fire retardant has a chemical structure shown in the general formula. Molecules of the environmentally friendly fabric fire retardant contain two flame retardation elements of phosphorus and silicon and multiple functional groups capable of reacting with a cellulose fiber fabric. The environmentally friendly fabric fire retardant is utilized for fabric flame retardation treatment. A fabric treated by the environmentally friendly fabric fire retardant does not produce after-flame and smoldering, has damaged part length less than 100 millimeters and a soft handle, and does not release formaldehyde.

Description

Technical field: [0001] The invention relates to an environment-friendly flame retardant in the field of textile functional finishing and its preparation method and application, in particular to a silicon-containing phosphonate reactive flame retardant and its preparation method and application. Background technique: [0002] There are usually two ways to prepare flame-retardant textiles. One is the additive type, that is, the flame retardant is mixed with the spinning dope to make the spun fibers have flame-retardant properties. The other is the post-finishing type, which is to perform flame-retardant finishing on the fabric. The flame retardancy of natural fiber textiles such as cotton fabrics can only be achieved by finishing. [0003] Among the durable flame retardant finishing agents for cotton fabrics, halogen-containing flame retardants have good flame retardant effects, but they are gradually replaced by halogen-free organic phosphorus due to the release of hydrogen...
