The preparation of traditional imaging film is prepared through retarding ink, utilizes the concrete retarding effect, then adopts the high-pressure water gun to wash out to form, and the shortcoming of this kind of method lies in retarding time unstable, retarding time reduces or becomes invalid under the high temperature state to need wash out with water, easily cause sewage, influence the environment. The common image concrete mainly adopts common concrete as a matrix, and when the wallboard is prepared, the wallboard has large thickness and large self weight, so that construction is difficult.

The cement hydration inhibition component is compounded by a plurality of inorganic salts and alcohol additives, has stronger cement hydration inhibition effect, can reduce the cement hydration degree of a UHPC cement concrete system, and reduces the surface strength of concrete.
And the performances of the printing ink are modified by adopting a plurality of coupling agents for compounding, the bonding strength of the transfer printing ink to different materials is enhanced, and the bonding strength of the printing ink to the surfaces of the bottom die and the concrete matrix is improved.
Further, the alcohol additive comprises methanol, ethanol, propanol, ethylene glycol, propylene glycol and glycerol. Alcohol additives such as propanol are used as hydration inhibition components to inhibit cement hydration, and interface modifiers are used to enhance the cohesiveness between cement and a transfer film.

Further, in the cement hydration inhibition component, 2 to 5 parts by weight of citric acid, 5 to 10 parts by weight of sodium pyrophosphate, 5 to 10 parts by weight of sodium tripolyphosphate, 2 to 5 parts by weight of sodium gluconate and 26 to 48 parts by weight of alcohol additive are calculated.
Further, in the alcohol additive, 2 to 5 parts by weight of methanol, 2 to 3 parts by weight of ethanol, 5 to 10 parts by weight of propanol, 5 to 10 parts by weight of ethylene glycol, 2 to 5 parts by weight of propylene glycol and 10 to 15 parts by weight of glycerol are calculated.

step S4, shaping the decorative wallboard: after the concrete is formed for 24-36 hours, turning over the pattern concrete member, removing the transfer film, cleaning the surface by a brush, and then spraying a protective agent.
The contact part of the concrete and the image is contacted with the hydration inhibition component and the interface modification component, so that the cement stops or slows down hydration, is adhered to the film, and after UHPC is hardened, the transfer film is removed, and the concrete contacted with the image part falls off along with the film. Thus, the scouring process of the concrete is avoided, the environmental pollution is reduced, and the hardening time of the concrete is not needed to be considered.
