The invention discloses coating for sintering of a hard alloy. The coating for the sintering of the hard alloy is obtained by sequentially carrying out the steps of dissolution, stirring, mixing, ball milling and discharging on PEG6000, Tween80, zirconium oxide, yttrium oxide, graphite powder, high purity water and ethyl alcohol which are matched in proportion. Compared with the prior art, the coating for the sintering of the hard alloy has the beneficial effects that the problems of existing most manufacturers that an extrusion angle is big, a product is easy to bend and crack, the coating is difficult to clean after sintering and the coating is strong in smell and does big harm to people and the environment are solved, a preparation technology is simple, raw material cost is low, and the obtained coating can realize a low-angle extrusion product, can endure repeated high-temperature sintering, produces no negative effect to performance or appearance of a product and is easy to clean, so that damage rate of a boat is greatly reduced; besides, the coating for the sintering of the hard alloy has no disgusting smell and is non-toxic, safe and environment-friendly.
