Problems solved by technology

However, the solubility of the existing functional cruciform hybrids in common spinning solvents or polymers is too high, resulting in low viscosity of the mixture after the preparation of functional masterbatches and blending with polymers such as polyester, which hinders the formation of polymers. Difficulty in processing
In addition, its melting point is not high, generally at 60-70°C, which puts forward certain requirements for its storage and transportation, and increases the cost of use
In addition, since the addition of low-molecular-weight ester-type additives will greatly improve the rheological properties of the polymer, too high a cross-shaped hybrid content in the polymer will also bring difficulties to the processing and molding of the polymer. The amount added is usually not more than 6-8wt%, and such a low amount of functional masterbatch is difficult to meet the corresponding functional requirements
Therefore, in the current preparation process of functional masterbatches, it is rare to use cruciform hybrids as functional additives.

Description

technical field [0001] The invention belongs to the technical field of functional master batches, and relates to a master batch containing cross-shaped hybrid porous materials and a preparation method thereof. Background technique [0002] Masterbatch, also known as masterbatch, is a plastic processing aid, which refers to a concentrate made of super-normally loaded functional additives in resin. When making plastic or fiber products, it is not necessary to add this kind of additive, but only need to add the corresponding masterbatch. Therefore, it is one of the most important forms of additive application in polymer production in the world today. It has the characteristics of simple process, convenient use, easy 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 content of additives or fillers in it is several times or even t...
