Step one, compounding process：First trough type mixing machine is cleaned out, then respectively ammonium polyphosphate modifying, triazines into charcoal
Agent and phosphorus nitrogen synergist are put into the trough type mixing machine, open stirring, rotate forward 20min, then invert 10min, and discharging is mixed
Close material；
Step 2, process of surface treatment：During compound described in step one continuously put into surface treating machine, setting surface treatment
The operating temperature of machine is 40 DEG C ~ 135 DEG C, opens conveyer belt and claims, and sets powder blanking frequency, then by surface conditioning agent by fixing
Feeder is added drop-wise to inside surface treating machine in the mixture for being transmitted by conveyer belt, then will be described before discharging
Mixture is crushed, then the mixture after crushing is removed, then through two-dimensional mixing machine it is well mixed after, obtain fabric coating with efficient
Halogen-free environment-friendlyflame flame retardant.
12. methods according to claim 11, it is characterised in that the efficient halogen-free environmental protection of fabric coating described in step 2
The particle diameter of fire retardant is D50=3 μm ~ 12 μm, D98=10μm ~30μm。
