A method for preparing a fireproof sol polyethylene corrugated pipe

[0020] Example 1

[0021] A preparation method of a fireproof sol polyethylene corrugated pipe includes the following steps:

[0022] (1) Take 3 parts by weight of ethylenediaminetetraacetic acid, add it to 80 times its weight in deionized water, stir evenly, add 1 part by weight of sodium carboxymethyl cellulose, and heat and stir at 50°C for 10 minutes to obtain Aqueous fiber dispersion;

[0023] (2) Take 10 parts by weight of ethyl orthosilicate and add it to the above aqueous fiber dispersion, stir evenly, add 10% ammonia water dropwise, adjust the pH to 11, stir at room temperature for 2 hours, add 0.8-1 weight Parts of coconut diethanolamide, stir evenly to obtain an amide sol dispersion;

[0024] (3) Take 3 parts by weight of ammonium polyphosphate and add it to 17-20 times its weight in deionized water, stir evenly, add 0.7 parts by weight of p-aminobenzene sulfonic acid, and heat and stir at 46°C for 3 minutes to obtain the carboxyl group Ammonium polyphosphate solution;

[0029] Example 2

[0030] (1) Take 4 parts by weight of ethylenediamine tetraacetic acid, add it to 90 times its weight in deionized water, stir evenly, add 2 parts by weight of sodium carboxymethyl cellulose, and heat and stir for 20 minutes at 60°C to obtain Aqueous fiber dispersion;

[0031] (2) Take 16 parts by weight of ethyl orthosilicate and add it to the above-mentioned aqueous fiber dispersion, stir evenly, add dropwise ammonia water with a concentration of 12%, adjust the pH to 12, stir at room temperature for 3 hours, and add 01 parts by weight Coconut oleic acid diethanolamide, stir evenly to obtain an amide sol dispersion;

[0032] (3) Take 3 parts by weight of ammonium polyphosphate, add it to 20 times its weight in deionized water, stir evenly, add 0.7 parts by weight of p-aminobenzenesulfonic acid, and stir at 50°C for 7 minutes to obtain carboxyl polyphosphoric acid Ammonium solution

[0033] (4) Mix 6 parts by weight of talc powder and 1 part by weight of cyanuric chl
