Embodiment 1
[0048] A preparation method of antimony-free water-based flame-retardant adhesive for fabric coating,
[0049] Step 1, raw material preparation, calculated by weight, including:
[0050]
[0051]
[0052] The total weight of raw materials is 100 parts
[0053] Step 2, the preparation of polyvinyl alcohol solution,
[0054] In a container with a stirring device and a heating device, add 6 parts of polyvinyl alcohol, add 30 parts of water, start the agitator, stir at a slow speed for 1-4 hours, start the heating device, raise the temperature to 50-95 ° C, continue Stir for 2 hours to fully dissolve the polyvinyl alcohol. Continue to stir at a slow speed, add bactericide, defoamer and crosslinking agent to obtain polyvinyl alcohol aqueous solution, and discharge for later use;
