The invention belongs to the technical field of polymer foam plastic, and particularly relates to a low-formaldehyde melamine foam material and a preparation method thereof. The low-formaldehyde melamine foam material is prepared from the following components in parts by weight: 25-45 parts of melamine, 15-25 parts of paraformaldehyde, 5-10 parts of glyoxal, 15-30 parts of water, 1-4 parts of a formaldehyde scavenger, 2-5 parts of titanium dioxide, 3-8 parts of an emulgator, 2-5 parts of a crosslinking agent, 4-9 parts of a foaming agent and 3-7 parts of a foam stabilizer. The low-formaldehydemelamine foam material has low free formaldehyde content, and is simple in technology and good in mechanical performance. 本发明属于高分子泡沫塑料技术领域，具体涉及种低甲醛三聚氰胺泡沫材料及其制备方法；由以下重量份数组成：三聚氰胺25～45份，多聚甲醛15～25份，乙二醛5～10，水15～30份，甲醛捕捉剂1～4份，二氧化钛2～5份，乳化剂3～8份，交联剂2～5份，发泡剂4～9份，匀泡剂3～7份，本发明游离甲醛含量低，工艺简单、力学性能好。
