Embodiment 1

[0018] A preparation method for a new fluorine-containing composite board material, the preparation technical scheme is as follows:

[0019] According to the number of parts by mass, weigh 8 parts of urea and 170 parts of deionized water and add them to the reaction kettle. After stirring and completely dissolving, put 95 parts of protein powder into the reaction kettle, control the reaction temperature at 35°C, and react for 3 hours. Use sodium hydroxide solution to adjust the pH of the system to 11, then heat to 60°C, and react for 40 minutes; after the reaction is completed, add 0.3 parts of dispersant sodium tripolyphosphate, 8 parts of plasticizer, and 2 parts of polyacrylamide Benzylidene camphor, 8 parts zinc cocoeth sulfate, 0.3 parts by weight PEG-8 / trifluoropropyl dimethicone copolymer, 0.03 parts of stearyl hydroxyethyl imidazoline Nitrogenium chloride, 32 parts of cross-linking agent and 13 parts of modified nano-filler, continue to stir at high speed for 90 minute...
