Embodiment 1
[0011] Embodiment 1: the production process steps are as follows:
[0012] 1) Configure cotton fiber flame-retardant coating glue: the component distribution ratio is approximately in parts by weight:
[0013] Water-based polyacrylate 50, intumescent halogen-free composite flame retardant 30, water 50, water-based sealing polyurethane 1, non-ionic surfactant (OP-10) 0.2, thickener (PTF) 0.5, water-based mineral oil defoaming Agent 1.2. Among them, the proportion of the composite flame retardant is by weight: basic flame retardant (ammonium polyphosphate: pentaerythritol: melamine = 15︰5︰5): flame retardant synergist (organophosphate, nano-montmorillonite) =25:5. The preparation method is to add water, OP-10 to the intumescent halogen-free composite flame retardant, add water-based polyacrylate, water-based sealing polyurethane, water-based mineral oil defoamer after emulsification and dispersion, and adjust the pH of the solution with ammonia water to 7~ 9. Then slowly add ...
Embodiment 2
[0017] Embodiment 2: the production process steps are as follows:
[0018] 1) Cotton fiber flame-retardant coating glue is configured, and its component proportions are: water-based polyurethane 80, intumescent halogen-free composite flame retardant 56, water 100, water-based sealing polyurethane 10, non-ionic surfactant (OP-10) 3.0, thickener BJ-100 2.0, water-based silicone 2.0. Among them, the proportion of the composite flame retardant is by weight: basic flame retardant (ammonium polyphosphate: pentaerythritol: melamine = 35: 20: 0.5): flame retardant synergist (zinc borate) = 55.5: 0.5. The preparation method is to add water, OP-10 to the intumescent halogen-free composite flame retardant, add water-based polyurethane, water-based blocked isocyanate, water-based mineral oil defoamer after emulsification and dispersion, adjust the pH of the solution with ammonia water = 7 ~ 9, Then slowly add thickener BJ-100 under stirring, and continue emulsifying and dispersing to obt...
Embodiment 3
[0024] Embodiment 3: the production process steps are as follows:
[0025] 1) Cotton fiber flame-retardant coating glue is configured, and its component proportions are water-based polyurethane 30, water-based polyacrylate 40, intumescent halogen-free composite flame retardant 75, water 80, water-based blocked isocyanate 5, Non-ionic surfactant (OP-10) 1.5, thickener P668 1.2, water-based silicone defoamer 0.5. Among them, the proportion of the composite flame retardant is by weight: basic flame retardant (ammonium polyphosphate: pentaerythritol: melamine = 40: 10: 15): flame retardant synergist (vermiculite, white microcapsule red phosphorus flame retardant) =65:10. The preparation method is to add water, OP-10 to the intumescent halogen-free composite flame retardant, add water-based polyurethane, water-based polyacrylate, water-based blocked isocyanate, water-based mineral oil defoamer after emulsification and dispersion, and adjust the pH of the solution with ammonia wate...
