[0026] Embodiment one The flame composite agent comprises the following components by weight: flame retardant 10%, polyester 20%, organic alcohol 20%.

[0027] The flame retardant is one or more of decabromodiphenyl ether and tetrabromobisphenol A.

[0028] The polyester is one or more of polyethylene terephthalate and polybutylene terephthalate.

[0029] The organic alcohol is one or more of ethanol, isopropyl alcohol, butanol, ethylene glycol and glycerol.

[0030] The preparation method of the flame composite agent comprises the following steps: Preparation: heat each material of the set components to 90 O C, then mix at 40O C is kept at ambient temperature for 1 hour; Mixing: after keeping warm, the components are loaded into the reaction kettle, and the stirring assembly in the reaction kettle stirs and mixes the materials in the reaction kettle in a cylindrical rotating track.

[0031] Because the material has a large viscosity, the stirring assembly in the reaction kettle stirs and mixes the material in a round bead rotating track, which can avoid the material with large viscosity adhering to the stirring assembly.

[0032] The rotating speed of the stirring assembly in step B is 15 revolutions per minute. According to the actual situation, the rotating number of revolutions is also feasible.

[0033] As shown in Figure 1 and Figure 2 The stirring assembly in step B includes a bracket 1, a transmission shaft 2, a stirring rod one 3 and a stirring rod two 4. The bracket 1 is fixed in the reaction kettle. The transmission shaft 2 is transversely arranged and axially fixed with the bracket 1. The transmission shaft 2 has a connecting end 2a at the end for connecting with the driving member. The stirring rod one 3 is spirally connected to the side of the transmission shaft 2. The stirring rod two 4 is spirally connected to the side of the transmission shaft 2. It also includes a support assembly. One end of the support assembly is connected to the transmission shaft 2, and the other end of the support assembly is connected to the stirring rod one 3 and the stirring rod two 4.

[0034] The thread direction of the stirring rod one 3 is opposite to that of the stirring rod two 4.

[0035] The support assembly includes a connecting plate 5 in the shape of a long sheet. The connecting plate 5 is arranged perpendicularly to the transmission shaft 2, and the inner end of the connecting plate 5 is fixed to the transmission shaft 2. The outer end of the connecting plate 5 has a recessed positioning recess two 5a. The coincident connection of the stirring rod one 3 and the stirring rod two 4 is embedded in the positioning recess two 5a.

[0037] The inner end of the connecting plate 5 has a recessed positioning recess one 5b which matches the side of the transmission shaft 2. The transmission shaft 2 is embedded in the positioning recess one 5b, and the transmission shaft 2 is fixed to the connecting plate 5 by welding.

Since the contact area of the stirring assembly with the materials is small, the materials with relatively high viscosity can be prevented from being excessively stirred, and the stability is effectively improved.

[0044] When the flame composite agent is used, it is added in the polyether at a weight ratio of 3-4%, and is used after being fully stirred for half an hour, mixed uniformly, and foamed.

[0045] Specifically, according to 100 parts by weight of polyether, 1.0 parts by weight of silicon oil L580, 3 parts by weight of the flame composite agent, 3 parts by weight of water, 0.2-0.3 parts by weight of a catalyst, and 41.5 parts by weight of isocyanate, the product is made into a sponge, aged for 24 hours, cut into a 1 cm thick sheet, and then the sponge is made to produce molten droplets by flame combustion and is combined with non-woven fabric.

[0046] The flame composite agent can effectively improve the bonding force after the flame composite operation, and has relatively high stability.

[0047] Meanwhile, the stirring assembly rotates in a ball shape in the preparation process, so that the materials in the reaction kettle are fully mixed, and the mixing stability is high.
