Environment-friendly composite board and processing technology thereof

The invention belongs to the technical field of composite board processing, and discloses an environment-friendly composite board and a processing technology thereof.The environment-friendly composite board comprises a base board, functional boards are arranged on the two sides of the base board, a damp-proof breathable layer is arranged on the side, away from the base board, of each functional board, and a damp-proof vapor-proof film is arranged on the side, away from the base board, of each damp-proof breathable layer; a protective layer is arranged on the side, away from the base plate, of the moisture-proof vapor-proof film. According to the environment-friendly composite board, the damp-proof breathable layer and the damp-proof vapor-proof film are matched, so that the environment-friendly composite board has good damp-proof performance, the probability of the sun crack phenomenon of the environment-friendly composite board is reduced, and the service life of the composite board is prolonged. 本申请属于复合板材加工
