23-35 parts of volcanic ash, 5-12 parts of microcrystalline cellulose, 3-6 parts of sulphur petroleum coke micro mist；
The adjuvant is made of the raw material of following parts by weight：5-9 parts of 0.1mol/l phosphate buffer solutions, glycine betaine 2-19
Part, SHD3-10 parts, 3-15 parts of methylcellulose, 5-10 parts of tristerin, 3-8 parts of Arabic gum, 5-15 parts of warm water, vinegar
Sour sodium 0.2-0.5 parts；Preparation method：Glycine betaine and methylcellulose are added to the water and impregnate 10-40min, rear 50-
500rpm/min is stirred for solution I；30-60 DEG C of 0.1mol/l phosphoric acid buffer is added in SHD, carbomer, sodium acetate afterwards
In solution, buffer solution heat preservation waits for that solute slightly soluble, rear 200-500rpm/min are stirred for solution II, finally by solution I, solution
II and tristerin be sent into the abundant defibrination of fiberizer, add 30-40 DEG C of warm water, start agitating device, 60-200rpm/
Min stirs 20min, makes material Ph6.0-8.5, up to adjuvant after natural cooling.
