The invention discloses a two-door refrigerator which comprises a main box body. The main box body is internally provided with a low-temperature warehouse, a cooling system and a control system. The cooling system comprises an evaporator, a condenser and a compressor, wherein the evaporator, the condenser and the compressor are connected through refrigerant pipes in series. The control system comprises a control circuit for controlling the compressor to work. The low-temperature warehouse is wrapped with a heat preservation layer. The heat preservation layer is composed of, by weight, 6.7 parts of silicate cement, 1.2 parts of titanium white powder, 1.1 parts of coal ash, 0.6 part of ceramic microbeads, 0.8 part of carboxymethylcellulose and 0.7 part of gypsum powder. According to the two-door refrigerator, the low-temperature warehouse is wrapped with the heat preservation layer resistant to corrosion, resistant to noise, resistant to aging and good in heat insulating performance, the heat preservation performance of the low-temperature warehouse is improved, and long-term energy consumption of the two-door refrigerator is lowered.
