The invention discloses a phase change latent heat environment-friendly energy-saving type building material and a preparation method thereof. The phase change latent heat environment-friendly energy-saving type building material comprises 50-80 parts of cement, 30-50 parts of diatomite, 0.5-3.5 parts of acetyl tributyl citrate, 1-5 parts of an aliphatic water reducer, 10-15 parts of poly-2,6-naphthalene acid ethyl ester fiber, 2-7 parts of expanded vermiculite, 30-50 parts of triethylene glycol monomethyl ether, 8-15 parts of sebacic acid, 5-10 parts of tetradecanoic acid and 12-20 parts of n-hexadecane. The method comprises the steps that the sebacic acid, the tetradecanoic acid and the n-hexadecane are mixed and stirred at the temperature of 130-150 DEG C; the expanded vermiculite and the triethylene glycol monomethyl ether are added, the temperature is decreased to be 80-120 DEG C, and stirring continues to be performed; the cement, the diatomite, the acetyl tributyl citrate, the aliphatic water reducer and the poly-2,6-naphthalene acid ethyl ester fiber are added into the mixture after the temperature is decreased to be 50-60 DEG C, the temperature is increased to be 90-130 DEG C, and a vaccumizing reaction is performed for 20-40 min; after cooling is performed, drying and pressing in a drying oven are performed, and then the phase change latent heat environment-friendly energy-saving type building material can be obtained. The building material is high in heat conductivity coefficient, good in fixation and formation and resistant to fire, meanwhile energy consumption is saved, and the comfort is improved.
