The invention discloses a uniform-compression prestressed glass member and a preparation method thereof, relating to the fields of safety glass and protecting glass. The uniform-compression prestressed glass member comprises a glass body, a restraining frame which is sleeved outside the glass body and is in the same shape with the glass body, and an expansion body between the glass body and the restraining frame. A metal frame-shaped material is used as a glass stress bearing structure, expanding agent cement or an expanding rubber strip is used as a bonding and fixing material and a filling material between the frame and glass, pressure stress is generated by the self-expansion performance of the expansion material and then is transferred into the plane of the glass to generate uniform pressure stress, and pull stress does not exist; the experiment result indicates that the structure has high strength and strength after destroy, and the glass member can obviously enhance the safety of the glass structure and
