Embodiment 1
[0035] First, pre-preparate an aqueous solution containing a water-based polyurethane molecule for later use. When the following reactions are to be performed, deionized water is further added to the aqueous solution of the water-based polyurethane molecule for dilution, and then surface-modified aluminum hydroxide particles are added. (particle size 1 and 8 μm), and stir until uniformly dispersed to become a diluted mixed aqueous solution.
[0036] Next, an aqueous solution of hydrophilically modified cross-linked molecules is prepared in advance, and the isocyanate groups (-NCO) on the surface of the cross-linked molecules are first reacted with water to form an emulsified droplet-shaped and hydrophilic film layer. Subsequently, the aqueous solution of the emulsified droplet-shaped cross-linking molecule is added to the above-mentioned diluted mixed aqueous solution, and stirred until uniform, so that a liquid coating is prepared. At this time, the liquid coating still contai...
Embodiment 2
[0046] The preparation method of the flame retardant coating of this embodiment is similar to that of Example 1. First, the aqueous solution of aqueous polyurethane molecules is prepared in advance for subsequent use. When the following reactions are to be performed, deionized water is further added to the aqueous solution of aqueous polyurethane molecules. Dilute, then add surface-modified aluminum hydroxide particles (particle size 8 μm) and further add a phosphorus-based flame retardant (such as ammonium polyphosphate), and stir until uniformly dispersed to form a diluted mixed aqueous solution.
[0047] Next, prepare an aqueous solution of hydrophilically modified cross-linked molecules in advance to obtain an aqueous solution of emulsified droplet-shaped cross-linked molecules, and add it to the above-mentioned diluted mixed aqueous solution, and stir until uniform, so that a liquid coating is prepared. The liquid paint at this moment still contains moisture, and its compo...
Embodiment 3
[0056] Embodiment 3 (control group):
[0057] The preparation method of the flame retardant coating of this embodiment is similar to that of Example 1. First, the aqueous solution of aqueous polyurethane molecules is pre-prepared for subsequent use. When the following reactions are to be carried out, deionized water is further added to the aqueous solution of aqueous polyurethane molecules to carry out Diluted, but no surface-modified aluminum hydroxide particles or phosphorus-based flame retardants are added to the diluted aqueous solution.
[0058] Next, prepare an aqueous solution of hydrophilically modified cross-linked molecules in advance to obtain an aqueous solution of emulsified droplet-shaped cross-linked molecules, and add it to the above-mentioned diluted mixed aqueous solution, and stir until uniform, so that a liquid coating is prepared. At this moment, the liquid coating still contains moisture, and its composition weight ratio is as shown in Table 5 below:
