The invention relates to a superhard composite material technology, and in particular, relates to an adhesive for synthesizing a polycrystalline cubic boron nitride material and a using method of theadhesive. The adhesive is an intermetallic compound; the intermetallic compound contains aluminum, titanium and M; M is selected from at least one of Cr, Nb, W, Mo and V; and the atomic ratio of titanium to aluminum in the intermetallic compound accounts for 90-95% of the intermetallic compound. The application of the adhesive comprises the steps: preparing adhesive particles and cubic boron nitride powder according to a volume ratio of the adhesive particles to the cubic boron nitride powder of (10-30):(70-90); after uniformly mixing, carrying out vacuum treatment; and after vacuum treatment,sintering in a high-temperature and high-pressure environment to obtain the polycrystalline cubic boron nitride. The adhesive disclosed by the invention provides necessary conditions for low-temperature preparation of high-performance polycrystalline boron nitride. The adhesive is reasonable in component arrangement, the application process is simple and controllable, the obtained product is excellent in performance, and large-scale industrial application is facilitated.
