Embodiment 1
[0062] A nano high-gloss moisture-proof impregnated paper, the impregnated paper includes a wear-resistant layer 1, a high-gloss hydrophobic layer 2, an anti-penetration adhesive layer 4 and a base paper layer 5 arranged sequentially from top to bottom, and the base paper layer 5 is printed with a pattern. The high-gloss hydrophobic layer 2 is made of organic silica gel embedded with nano-alumina particles 21 .
[0063] The impregnated paper also includes a flash layer 3, the upper surface of the flash layer 3 is adhesively connected to the lower surface of the high-gloss hydrophobic layer 2, and the lower surface of the flash layer 3 is bonded to the upper surface of the anti-penetration film layer. joint connection; the flash layer 3 is made of melamine glue embedded with nano-pearl powder 31.
[0064] The particle size of the nano-alumina particles 21 is 15-30nm, and the distribution density of the nano-alumina particles 21 in the organic silica gel layer is 40-70 pieces / cm...
Embodiment 2
[0091] The difference between this embodiment and above-mentioned embodiment 1 is:
[0092] Described organosilica gel is made from the raw material of following weight part:
[0093]
[0094] Described organosilica gel is made by following steps:
[0095] Step A: According to parts by weight, premix methyl vinyl polysiloxane resin, methyl hydrogen polysiloxane resin and hydroxyl-terminated polydimethylsiloxane at a speed of 700rpm and a temperature of 28°C Under the condition of stirring for 23min, material A was obtained;
[0096] Step B: In parts by weight, vinyltrimethoxysilane and dibutyltin dilaurate are respectively added to the material A prepared in step A, and stirred while adding at a speed of 1050 rpm. After the addition of the materials is completed, the Stirring for 34 minutes at a rotational speed of 1850 rpm to obtain material B;
[0097] Step C, mixing and stirring silicon carbide, brightener, hydrophobic agent and flame retardant according to parts by w...
