Embodiment 1
[0039] (1), 0.2g diammonium hydrogen phosphate is dissolved in deionized water, is made into the solution that concentration is 5%, then joins in 1000g high-ammonia latex and stirs evenly, leaves standstill for half an hour, makes the high-ammonia latex processed ;
[0040] (2), 1.5g sodium pyrosulfite is dissolved in deionized water, is made into the solution that concentration is 0.5%, joins in (1) made in the high ammonia latex that has been processed, stirs evenly, makes the high ammonia that has been processed again latex;
[0041] (3), use 3% formic acid solution or 5% acetic acid solution to coagulate the high ammonia latex processed again by (2), make high ammonia rubber clot;
[0042] (4) Dissolve 1.5g sodium pyrosulfite in deionized water, make a solution with a concentration of 0.5%, spray it on the high ammonia latex clot, ripening, tableting, and granulation obtained in (3), to obtain high ammonia rubber Wet gel particles;
[0043] (5), soak the high ammonia ru...
