Abstract

The present invention relates to the field of functional master batches, and specifically discloses a functional master batch for strengthening the tensile strength of polypropylene. The functional master batch is prepared from a carrier resin, an alicyclic epoxy resin, a cross-linking agent, nanometer alumina powder, nano-scale porcelain powder, glass fiber, nanometer graphene, nano-scale wood powder, a coupling agent and a dispersant, wherein the carrier resin is a polypropylene resin, the cross-linking agent is preferably one selected from diisopropylbenzene hydroperoxide, triethylenetetramine, diethylenetriamine and diethylaminopropylamine, the coupling agent is preferably one selected from a vinyl silane coupling agent, an aminosilane coupling agent and an epoxy silane coupling agent, and the dispersant is preferably one selected from lignin fiber, bamboo pulp fiber and zinc stearate. According to the present invention, the cross-linking compactness of polypropylene is synergistically improved by cross-linking polypropylene with the alicyclic epoxy resin and by using nanometer alumina powder, porcelain powder and wood powder as the composite nucleating agent, the tensile strength is improved, and the mechanical property of the polypropylene resin is further improved through glass fiber and nano-graphene.

Description

technical field [0001] The invention relates to the field of functional masterbatches, in particular to a functional masterbatch for strengthening the tensile strength of polypropylene. Background technique [0002] Polypropylene (PP) is a thermoplastic resin prepared by propylene polymerization. It is non-toxic, odorless, tasteless, milky white and highly crystalline. It is divided into isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene according to the position of the methyl group. There are three kinds of propylene, in which the methyl groups are arranged on the same side of the main chain of the molecule, which is called isotactic polypropylene. If the methyl groups are arranged randomly on both sides of the main chain of the molecule, it is called atactic polypropylene. The two sides of the main chain are called syndiotactic polypropylene. In general industrially produced polypropylene resins, the isotactic structure content is about 95%, and...
