Embodiment 1

[0025] A preparation method of a flame retardant finishing agent, said preparation method mainly comprising the following steps:

[0026] S1: Dissolving 4 parts of the urea in 300 parts of water, adding 5 parts of the compound A, maintaining the pH of the mixture at 8-9 with ammonia water, and reacting at 100° C. for 3 hours;

[0027] S2: the temperature is lowered to 50°C, and after stabilization, 12 parts of the polyol are added and stirred evenly;

[0028] S3: keep the temperature constant, slowly add 20 parts of the emulsifier and stir;

[0029] S4: The temperature is returned to room temperature, and 6 parts of the dicyandiamide are added with stirring to finally obtain the flame retardant finishing agent.

Embodiment 2

[0031] A preparation method of a flame retardant finishing agent, said preparation method mainly comprising the following steps:

[0032] S1: Dissolve 6 parts of the urea in 350 parts of water, add 15 parts of the compound A, use ammonia water to maintain the pH of the mixture at 8-9, and react at 150°C for 2 hours;

[0033] S2: The temperature is lowered to 65°C, and after stabilization, 18 parts of the polyol are added and stirred evenly;

[0034] S3: keep the temperature constant, slowly add 50 parts of the emulsifier and stir;

[0035] S4: The temperature is returned to room temperature, and 10 parts of the dicyandiamide are added with stirring to finally obtain the flame retardant finishing agent.

Embodiment 3

[0037] A preparation method of a flame retardant finishing agent, said preparation method mainly comprising the following steps:

[0038] S1: Dissolving 8 parts of the urea in 400 parts of water, adding 20 parts of the compound A, maintaining the pH of the mixture at 8-9 with ammonia water, and reacting at 110° C. for 3 hours;

[0039] S2: The temperature is lowered to 90°C, and after stabilization, 20 parts of the polyol is added and stirred evenly;

[0040] S3: keep the temperature constant, slowly add 70 parts of the emulsifier and stir;

[0041] S4: The temperature is returned to room temperature, and 15 parts of the dicyandiamide are added with stirring to finally obtain the flame retardant finishing agent.

Abstract

The invention provides a textile flame retardant finishing agent, and the textile flame retardant finishing agent is prepared from at least the following raw materials by weight: 5-20 parts of a compound A, 4-8 parts of urea, 6-15 parts of dicyanodiamide, 10-50 parts of an emulsifier, 10-20 parts of polyol, and 200-500 parts of water. The invention also provides a method for preparing the textileflame retardant finishing agent and use of the textile flame retardant finishing agent in textiles. The beneficial effects of the textile flame retardant finishing agent are as follows: the textile flame retardant finishing agent is simple in preparation process, high in yield, green and environmentally-friendly, after the textile flame retardant finishing agent is used for finishing pure cotton fabrics, polyester fiber and acrylic fiber, the flame retardant strengths of the finished pure cotton fabrics, polyester fiber and acrylic fiber are improved; in the finishing agent, dimethiconol hyoroxystearate and secondary alcohol ethoxylate effectively improve the wrinkle resistance of the textiles.

Description

technical field [0001] The invention relates to the field of textile dyeing and finishing, in particular to a flame-retardant finishing agent for textiles and a preparation method thereof. Background technique [0002] Flame retardants commonly used in flame retardant fabrics are divided into three categories according to flame retardant elements. 1. Halogen-containing flame retardant: During the thermal decomposition process, substances that capture and transmit combustion free radicals are decomposed, which can dilute the combustible gas generated during fiber cracking, or cut off contact with air. 2. Phosphorus-containing flame retardant: Phosphoric anhydride or phosphoric acid produced during the combustion process promotes dehydration and carbonization of textiles, preventing or reducing the generation of flammable gases. At the same time, when phosphoric anhydride is thermally decomposed, it forms a glass-like melt that covers the fabric, prompting its oxidation to ge...
