A holographic material and a preparation method therefor, a holographic optical element, a holographic device, and a preparation method for a volume holographic grating. The preparation method for a holographic material comprises: providing a blocked polyisocyanate, a first compound, a polymerizable monomer, a photoinitiator, and other additives; and uniformly mixing the components under a light-proof condition to obtain a holographic material. In this way, a second-order holographic material can be pre-mixed for long-term storage, a start timing of a first-order reaction can be controlled, and a preparation process can be improved.
