Embodiment 1
[0053] A preparation process for glue, comprising the following steps:
[0054] S1. Pre-drip preparation:
[0055] S1-1: Mix 15kg hydroxyethyl cellulose, 3kg organic bentonite and 8kg aliphatic mineral oil to prepare a mixed solution;
[0056]S1-2: Mix 25kg of emulsifier with 2000kg of water A, stir for 30 minutes, add 90kg of acrylic acid and 2.5kg of plasticizer, then add 6000kg of butyl acetate, stir, when butyl acetate is added to half, add the preparation in S1-1 The obtained mixed solution and the defoamer with a total amount of 6% of the defoamer added, the defoamer was dissolved in 15 times the mass multiple of water B and then added, and the stirring was continued for 40min to obtain the front drop feed;
[0057] S2, glue preparation:
[0058] S2-1: Mix the remaining amount of water A in the raw material with 5kg of sodium bicarbonate, add 15kg of pre-initiator-sodium persulfate when the temperature rises to 80°C, stir for 5min and then add the pre-dropping material...
