The invention relates to a Y-beta/MCM-41 double microporous-mesoporous composite molecular sieve and a preparation method thereof. The molecular sieve is prepared by compounding Y and beta double microporous zeolites with an MCM-41 molecular sieve, and Y and beta microporous phases are tightly coated by an MCM-41 hexagonal mesoporous phase; and a mixed surfactant of hexadecyl trimethyl ammonium bromide serving as a cationic surfactant and polyethylene glycol octyl phenyl ether serving as a nonionic surfactant is taken as a template, pretreated inorganic silicon sources of the double microporous phases and a synthesis mesoporous phase are introduced into a system respectively, the pH value of the system is regulated to reach required acidity by inorganic acid, and hydrothermal crystallization is performed to obtain the Y-beta/MCM-41 double microporous-mesoporous composite molecular sieve which has adjustable silicon-to-aluminum ratio and content of the microporous phases and can be used without ion exchange. The method is easy and convenient to operate, has high repeatability and is environmental-friendly; and a product has high catalytic reaction performance when used for a hydrocracking catalyst carrier material.
