Phosphor polyamide flame retardant

Phosphor polyamide flame retardant

Through times of different phosphate dosage of polyamide fiber flame retardant agent, additives, dipping temperature, and time after single factor experiment to explore, adopt the method of orthogonal test, the four main factors to influence the properties of flame retardant, flame retardant agent, the dosage of additives, the immersion temperature and immersion time for discussion.

The effect size of the average residual flame time was: > leaching time > immersion temperature > agent dosage; The effect size of the average flame time is: soaking time > flame retardant dosage = immersion temperature > auxiliary dosage; The effect size of the average burning length is: > auxiliary dosage, > immersion time, > dip temperature.

The main influencing factors for the comprehensive balance analysis of various indicators are the amount of phosphor nylon flame retardant, followed by the time of leaching, then the leaching temperature, and finally the dosage of auxiliaries. The optimum technological parameters are 200 g/L for phosphine polyamide flame retardant. Dosage of auxiliaries 15 g/L, impregnation 60< 1, x3 h.

Under the condition of the optimal finishing process, after finishing the fabric washed 15 times measured: the average residual flame time 6. 5 s, 3 s average droplet flame time, average length of 5. 85 cm, the flame retardant performance index can reach the standard American aviation fire (< 15 s, the average residual flame time average drops < < 5 s, the average combustion flame time length 20.3 cm). The formaldehyde content of fabric was 0.43 mg/kg after the optimal finishing process. Therefore, the content of formaldehyde content of the fire-retardant finishing is far lower than that of the relevant regulations (infants' clothing <20 mg/kg, adult clothing is 75 mg/kg), which is in line with the ecological and environmental protection requirements of post-textile finishing.

Through single factor experiment: flame retardant performance with the increase of phosphate dosage of polyamide fiber flame retardant, dosage of additives on the properties of flame retardant effect was not significant, dipping temperature is high, the longer the dipping time can make the flame retardant performance increase.

The main influencing factors are the dosage of flame retardant, the second is the time of leaching, then the dip temperature, and finally the dosage of auxiliaries. The optimal optimal finishing process is 200 g/L of flame retardant, and the penetration agent 15 &/ L. The formaldehyde content of the fabric is 0.43 mg/kg, which meets the ecological and environmental protection requirements after textile. After washing 15 times, its flame retardant performance still meets the American aviation fire standards.

Flame retardants (d) and/or (e) in the gas phase have the following advantages, namely that they reduce the ignition tendency and help the flame of textile fibers to be extinguished. This is because the chemical properties of the volatile products or fuels that are produced by heat degradation react with oxygen in the flame, and their chemical properties become very similar. As a result, the effect of the flame retardant can be guaranteed by either cutting off oxygen (e) or generating interference free radicals ((f)).

According to cost and benefit, antimony - halogen flame retardant is the most successful flame retardant in the field of bulk polymer and backcoated textiles. Unlike the fiber - containing and nitrogen - based fiber reactive durable flame retardants (see below), they are usually used as a backcoating agent with resin adhesives.

In terms of textiles, most antimony - halogen systems are composed of antimony trioxide and brominated organic molecules (e.g., DBDPO) or hexabromocyclic tridecane (HBCD). Once heated, these substances release HBr base and Br. The base.
R, CH2, H and OH groups are part of the flame oxidation chain reaction, which consumes fuel (RCH3) and oxy
gen.

Fabric flame retardant can handle all kinds of cloth, twill, flannelette, canvas, linen cloth, non-woven fabrics and their finished goods (such as: clothing, cloth cap, a pipe, the curtain of entertainment venues, tent cloth, curtain, the venue troupe set, security bags, etc.) and various knitwear (such as: sweaters, towel cloth, gloves, carpet, etc.).
