Nucleating agent, composition for preparing transparent toughened nylon material, transparent toughened nylon material and preparation method of transparent toughened nylon material

The invention provides a nucleating agent, a composition for preparing a transparent toughened nylon material, the transparent toughened nylon material and a preparation method of the transparent toughened nylon material, and belongs to the technical field of nylon material modification. The nucleating agent can reduce the intermolecular hydrogen bond acting force in the macromolecular alloy nucleating process, so that the nucleating agent does not agglomerate in a nylon-K resin system, the dispersity is better, and the nucleating point is increased. The composition for preparing the transparent toughened nylon material comprises the following components in parts by weight: 60-90 parts of transparent nylon resin, 10-25 parts of K resin, 1-15 parts of toughening agent and 0.5-1 part of nucleating agent. The nucleating agent pretreats transparent nylon and K resin, promotes formation of polymer alloy crystal nucleuses, increases the crystallization speed of the polymer alloy, and ensuresthat the crystallinity o
