Embodiment 1
[0032] 20 parts of polyacrylamide, 15 parts of melamine, 35 parts of ammonium polyphosphate, 8 parts of cyclodextrin, 42 parts of formaldehyde, 12 parts of vermiculite, 18 parts of perlite, 12 parts of ammonium dihydrogen phosphate, 6 parts of nano-zinc borate , 32 parts of water.
[0033] The specific steps include: (1) First, dissolve polyacrylamide, melamine, ammonium polyphosphate and cyclodextrin in formaldehyde according to the formula ratio, then stir and heat to 80°C for 22 minutes; then adjust the pH of the above reaction solution It is neutral; (2) Place vermiculite, perlite, ammonium dihydrogen phosphate and nano-zinc borate in water according to the formula ratio, stir evenly, then heat to 80℃, react for 20 minutes, and then adjust the pH of the reaction solution to 4-5 (3) Then the steps (1) and (2) are mixed and uniformly coated on the outer surface of the cabinet according to the weight ratio of 1:1, and painted 3-5 coats, each with an interval of 2.5h, and the coa...
Embodiment 2
[0035] The fireproof coating includes: 24 parts of polyacrylamide, 18 parts of melamine, 28 parts of ammonium polyphosphate, 8 parts of cyclodextrin, 43 parts by weight of formaldehyde, 18 parts of vermiculite, 28 parts of perlite, and 14 parts of ammonium dihydrogen phosphate Parts, 9 parts of nano zinc borate, 33 parts of water. The preparation steps are the same as in Example 1.
[0036] The fireproof performance of the fireproof board prepared by the present invention is shown in Table 1 below:
[0037] Table 1 Fire performance of Example 1-2
[0038]
[0039] By testing the fire resistance of the examples, it is also found that the oxygen index of the samples 1-2 of the present invention is between 40-50, and the formaldehyde emission is less than 1.0 mg / L. It can be seen from the above-mentioned embodiments that the product of the present invention has the advantages of good fire resistance and can be effectively applied to the cabinet fireproof board.
