Embodiment 1
[0023] A manufacturing process of a cement-based environment-friendly mold, the steps comprising:
[0024] (1) Solid waste preprocessing: Repeatedly crush and sieve the recovered construction solid waste so that the average particle size is 2.5mm, and the utilization rate of recycled construction waste is over 80%;
[0025] (2) Mixing: mix the raw materials for mold preparation with water according to a certain ratio. 1 part of auxiliary agent, each auxiliary agent composition includes: 55% binder, 20% stabilizer, 15% early strength agent and 10% water reducing agent, the mixing ratio of raw material and water is 2:1, and it is prepared into a paste;
[0026] (3) Injection molding: the pressure in the pressure system is set to 40MPa, and the pasty raw material is injected into the mold device under high pressure;
[0027] (4) Holding pressure: carrying out pressure holding before mold molding and solidification, the pressure of holding pressure is 10MPa, and the time is 5h; ...
