Abstract

The invention discloses a nickel-maleate-grafted polypropylene ionomer as well as a preparation method and an application thereof. The nickel-maleate-grafted polypropylene ionomer is prepared by adding and melting polypropylene, an initiator, nickel maleate, an antioxidant and a grafted additive in parts by weight in an extruder. The preparation method of the ionomer is simple and free of secondary pollution, and the ionomer has multiple functions of nucleation and compatibilization; in glass fiber reinforced system, the compatibility of the glass fiber and a matrix can be increased and meanwhile, the weather resistance of the system can be improved; and in a filling system, the compatibility of the powder and a matrix can be increased and meanwhile, the strength and modulus of the material can also be improved. By modifying glass fiber reinforced polypropylene or inorganic filler polypropylene with the ionomer, the flexural modulus, tensile strength and notch impact strength of a composite material can be improved and the weather resistance of the material can be increased by virtue of the chelated metal ions.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a nickel maleate grafted polypropylene ionomer and a preparation method and application thereof. [0002] technical background [0003] Ionic polymers are referred to as ionomers, also known as ionomers, which refer to macromolecular main chains containing a small amount of ionizable groups (the molar content of ionic groups is not more than 15%), and are partially neutralized by metal ions Or fully neutralized salt-forming polymers. Since ionomers have metal ionic bonds in addition to covalent bonds, they can "apparently cross-link" adjacent polymers, and the polarities of ionic groups and hydrocarbon main chains are very different, the general tendency In the formation of its enriched region - ion clusters. [0004] Nickel maleate grafted polypropylene ionomer molecules contain non-polar macromolecular chain polypropylene structure, while c...
