[0002] Flame-retardant resins are widely used in transportation, furniture, and construction, effectively preventing and slowing the spread of flames. They are chemical additives used to improve the combustion properties of flammable materials. Some new flame-retardant resins have a melting point above 180°C and are thermosetting. If the temperature is too high, they solidify and become difficult to remelt and shape, making them difficult to process and prohibitive for mass production.

During the preparation process, due to temperature fluctuations, the new flame-retardant resins are prone to solidification and uneven mixing problems, thereby affecting the quality of the flame-retardant resins. At the same time, conventional production methods make it difficult to control the width and thickness of the new flame-retardant resins after solidification and molding, and subsequent workstations are required to perform shape processing, which increases the workload of subsequent workstations and reduces production efficiency.

The output end of the lifting cylinder 8 passes through the crossbeam 6 and is connected to a heatable heating platen 9. The lifting cylinder 8 drives the heating platen 9 to evenly extrude the material in the container 10 from the coating discharge pipe 13 to the steel strip of the steel strip cooler 1; a mixer 3 and a mold temperature controller 2 for stirring the material in the container 10 are installed on the side of the base 4. The mold temperature controller 2 is connected to the insulation shell 15 through a connecting pipeline, and heats the container 10 by circulating oil into the insulation shell 15. The length of the steel belt of the steel belt cooler 1 is designed according to the solidification time of the flame retardant resin, followed by a slicing process; the heating platen 9 and the coating discharge pipe 13 need to be heated to the set temperature in advance, and the material can only be discharged after the temperature is constant. The heating platen 9 and the coating discharge pipe 13 are both electrically heated.

The discharging mechanism is used to discharge the material in the container 10.

[0059] The inner wall of the container 10 is cylindrical and corresponds to the shape of the heating platen 9 .

The material in the inner pipe 1303 is evenly coated onto the steel strip cooler 1 through the flat elbow 1306. The electric heating cable 1304 has a cable and connector. The insulation layer 1302 and the heat shrink tubing 1301 are located outside the electric heating cable 1304, and heating it with electricity prevents the material in the inner pipe 1303 from solidifying.

[0064] The bottom of the container 10 is equipped with several guide wheels 16, and the outer wall of the heat-insulating shell 15 is equipped with symmetrically arranged handles 17. The guide wheels 16 and the handles 17 make it convenient for operators to move the container 10.

[0065] The steel strip cooler 1 is provided with a nozzle 14 mounted below the steel strip, which sprays coolant onto the steel strip. The nozzle 14 sprays coolant onto the steel strip to solidify the material when it is cooled, thereby completing the preparation of the flame retardant resin.

[0066] This embodiment provides a constant temperature preparation system for flame-retardant resin. By providing a mold temperature controller 2 and an insulation shell 15, the temperature inside the container 10 is stabilized and maintained between 180°C and 220°C, thereby maintaining the fluidity of the material in the container 10.

After the stirring is completed, the material in the container (10) is mixed and stirred for the second time by the mixer (3), the stirring speed is set to 50 rpm, the dispersion speed is set to 1000 rpm, and the second mixing and stirring time is set to 5 min; S7. After the second mixing and stirring is completed, the material in the container (10) is dispersed and accelerated for the first time by the mixer (3), the stirring speed is set to 100 rpm, the dispersion speed is set to 1000 rpm, and the first dispersion acceleration time is set to 10 min; S8. After the first dispersion acceleration is completed, the inorganic particulate material is added to the container (10), and then the material in the container (10) is mixed and stirred for a third time by the mixer (3), the stirring speed is set to 100 rpm, the dispersion speed is set to 1000 rpm, and the third mixing and stirring time is set to 10 min; S9. After the third mixing and stirring is completed, the inorganic particulate material is added to the container (10), and then the material in the container (10) is mixed and stirred for the fourth time by the mixer (3), the stirring speed is set to 100 rpm, the dispersion speed is set to 1000 rpm, and the fourth mixing and stirring time is set to 5 min; S10. After the fourth mixing and stirring is completed, the material in the container (10) is dispersed and accelerated for the second time by the mixer (3), the stirring speed is set to 100 rpm, the dispersion speed is set to 1000 rpm, and the second dispersion acceleration time is set to 10 min; S11. After the second dispersion acceleration is completed, a curing agent is added to the container (10), and then the material in the container (10) is mixed and stirred for the fifth time by the mixer (3). The stirring speed is set to 100 rpm, the dispersion speed is set to 1500 rpm, and the fifth mixing and stirring time is set to 10 min; S12. The heating platen (9) and the coating discharge pipe (13) are heated to 200°C and the temperatures of the heating platen (9) and the coating discharge pipe (13) are ensured to be stable. The container (10) is then moved to the bottom of the heating platen (9); S13. The lifting cylinder (8) extends, driving the heating platen (9) to move downward to squeeze the material in the container (10), so that the material in the container (10) is evenly coated on the steel strip of the steel strip cooler (1) through the coating discharge pipe (13); S14. After the material on the steel strip cooler (1) solidifies, it is transported to the next process.

7. The method for preparing a flame retardant resin according to claim 6, wherein: During the preparation of the flame retardant resin, the mold temperature controller (2) continuously heats the container (10).

8. The method for preparing a flame retardant resin according to claim 6, wherein: In S13., the thickness of the material coated on the steel strip cooler (1) is less than 3 mm.
