Reinforced rock wool fireproof composite board

The utility model discloses a reinforced rock wool fireproof composite board. The utility model relates to the technical field of environment-friendly building materials. The technical problem that anexisting rock wool board is not ideal in fireproof performance is mainly solved. The rock wool board comprises a first rock wool layer, a second rock wool layer and a third rock wool layer which arebonded with one another from inside to outside, glue adopted when the adjacent rock wool layers are bonded is urea-formaldehyde resin; a plurality of reinforcing metal pipes are uniformly distributedin the third rock wool layer; all the reinforcing metal pipes are parallel to each other and are adjacent at equal intervals; reinforcing steel bars are arranged on all the reinforcing metal pipes ina surrounding mode. The two ends of each reinforcing steel bar sequentially penetrate through the second rock wool layer and the first rock wool layer and are connected with each other on the outer surface of the first rock wool
