preparation example Construction
[0036] The preparation method process of the cotton topping agent of the embodiment of the present invention is:
[0037] Prepare the adjusted phosphine solution with a concentration of 5%-10%, the iodophenylchloroacetic acid solution with a concentration of 2%-5%, and the p-chlorotoluene solution with a concentration of 10%-15%, and let it stand for 12 hours;
[0038] To make a suspension of pichamid, mix pichamid and hydroxypropyl methylcellulose according to parts by weight, add water to 50 times the weight of the mixed ingredients, stir to make a suspension, and let it stand for 12 hours;
[0039] Mix the above-mentioned solutions and suspensions, add β-methylnaphthalene, isonicotinic acid, and di-sec-octyl sodium maleate sulfonate, mix them, and stir in a reaction kettle for 30-40 minutes to obtain a cotton topping agent.
[0040] During the stirring process in the reactor, according to the specific gravity of the suspension, the stirring speed at different temperature sect...
