Under the conditions of roast 35min, when it naturally cools to 50 DEG C, heat preservation for standby use；
Step 3: first taking complex cement, multiple emulsion to be added in batch mixer 7min is mixed, then by pearlife, step 1
Chopped sepiolite cashmere, the halloysite clay of step 2 and eakleite, which are added to jointly in batch mixer, to be continued to stir 20min, finally
Under agitation, composite water-repellent, composite coupler, composite glue powder and epoxychloropropane grafting, copolymerization and modification are sequentially added
Gelatine stirs 65min.
