The invention belongs to the technical field of macromolecular foamed plastics, and particularly relates to a hydrophobic melamine formaldehyde resin foamed plastic and a preparation method thereof. The hydrophobic melamine formaldehyde resin foamed plastic comprises, by weight, 30-40 parts of melamine formaldehyde, 20-30 parts of paraformaldehyde, 1-2 parts of stabilizers, 15-25 parts of water, 4-7 parts of emulsifiers, 2-4 parts of curing agents, 5-8 parts of foaming agents, 3-6 parts of blowing promoters and 5-20 parts of hydrophobic agents. The hydrophobic melamine formaldehyde resin foamed plastic is simple in process, low in cost and strong in hydrophobic property. 本发明属于高分子泡沫塑料技术领域，具体涉及种疏水性三聚氰胺甲醛树脂泡沫塑料及其制备方法，由以下重量份数组成：三聚氰胺30～40份，多聚甲醛20～30份，稳定剂1～2份，水15～25份，乳化剂4～7份，固化剂2～4份，发泡剂5～8份，发泡助剂3～6份，疏水剂液5-20份；本发明工艺简单、成本低、疏水性强。
