Abstract

The invention relates to a flame-retardant antibacterial master batch with a metal modified cross esterification compound and a preparation method of the flame-retardant antibacterial master batch. The metal modified cross esterification compound is uniformly mixed with a substrate and other components to prepare the flame-retardant antibacterial master batch through melting extrusion. The prepared master batch is mainly composed of the substrate and the metal modified cross esterification compound which is uniformly distributed in the substrate, the metal modified cross esterification compound is a network polymer formed by a cross esterification compound and metallic ions through cross-linking, the metal modified cross esterification compound has the properties of insolubility and unmeltability, cannot be dissolved in an aromatic hydrocarbon solvent, an aliphatic hydrocarbon solvent, an alicyclic hydrocarbon solvent, a halohydrocarbon solvent, an alcohol solvent, an ester solvent, aketone solvent, acetonitrile, pyridine, phenol, and N,N-dimethyl formamide or N,N-dimethylacetamide at 80 DEG C or less and is not molten within a room temperature range T, T is greater than or equalto 380 DEG C. The preparation method is simple in process and low in cost, and the prepared product is high in functional component content and easy to process and mold.

Description

technical field [0001] The invention belongs to the technical field of functional masterbatches, and relates to a flame-retardant and antibacterial masterbatch containing metal-modified cruciform ester compounds and a preparation method thereof. Background technique [0002] Masterbatch, also known as masterbatch, is a kind of plastic processing aid, which is a concentrate made of plastic additives attached to resin in a super-normal amount. When manufacturing plastic products, it is not necessary to add this kind of plastic additive, but only need to add the corresponding masterbatch. Therefore, it is one of the most important forms of application of plastic additives in the world today. It has the characteristics of simple process, convenient use, easy realization of production automation and high productivity. The masterbatch often contains various additives, fillers and a small amount of carrier resin. Due to the addition characteristics of the masterbatch, the conten...
