The invention belongs to the field of synthesis of polycrystalline diamond compacts, and particularly relates to a heat preservation and pressure transmission material for synthesizing the polycrystalline diamond compacts. The heat preservation and pressure transmission material for synthesizing the polycrystalline diamond compact is mainly prepared from powder and water glass. The powder material comprises the following components in parts by mass: 10-15 parts of sodium chloride, 35-85 parts of zirconium oxide aggregate and 3-55 parts of a magnesium oxide gap filling material; the magnesium oxide interstitial material comprises flaky magnesium oxide and porous magnesium oxide. According to the heat-preservation and pressure-transmission material disclosed by the invention, under the matching action of the zirconium oxide and the magnesium oxide, the sodium chloride has good flowability, a good heat-preservation and pressure-transmission effect can be achieved, and the problems of relatively large internal te
