Abstract
Description
technical field
[0001] The invention belongs to the technical field of preparation of auxiliary agents for polymer materials, and in particular relates to a preparation method of a multifunctional and high-efficiency beta nucleating agent for isotactic polypropylene materials. Background technique
[0002] Polypropylene (PP) is a semi-crystalline polymer, which can produce crystalline forms such as α, β, γ, δ and pseudo-hexagonal states according to different crystallization conditions. PP generally produces a relatively stable and common α-crystal structure under ordinary processing conditions. Since the β crystal structure is less stable than the α crystal structure, it can only be obtained under special conditions, such as under the action of a certain temperature gradient field, shear force field, or in the presence of a β nucleating agent. In addition to maintaining the good comprehensive properties of the α crystal form, the β crystal form PP has the advantages of hig...
