Problems solved by technology

This method solves the compatibility problem through the formation of chemical bonds, but the key to the method lies in the formation of chemical bonds, which makes the materials that can be applied very limited
At the same time, as a result of the chemical reaction, the phase change temperature and enthalpy of phase change materials are greatly affected.
directly lead to changes in the quality of the masterbatch
Although the compatibility problem is solved, a new problem that has a greater impact on the polymer masterbatch is introduced

Abstract

The invention provides a master batch capable of intelligently regulating temperature and a preparation method of the master batch. The master batch contains surface-hydrophobic phase-changed microcapsules; common microcapsules are surface-hydrophilic, and are poor in compatibility with polymer base material in processes such as granulation and spinning, so that not only is the performance of the master batch reduced, but also the microcapsule loss is very high; the phase-changed microcapsules provided by the technical scheme are surface-hydrophobic, and are good in compatibility with polymer base material and excellent in heat resistance. According to the preparation method, the selectable polymer base material types are wide, the operability is strong, the cost is low, and the popularization is facilitated. The master batch is used for the field of melt spinning, non-woven fabric and thin film production, plastic injection moulding and the like, and active roles are played for product quality and market competitiveness improvement.

Description

technical field [0001] The invention relates to a functional masterbatch material, in particular to an intelligent temperature-regulating masterbatch and a preparation method thereof. Background technique [0002] Masterbatch is an important polymer intermediate product to facilitate transportation, storage and processing. Masterbatch has a wide range of uses, such as various plastic basins, barrels, films, etc. in daily life; it is used in the textile industry to manufacture non-woven fabrics, fibers, shoe materials, etc.; it is used in building materials to produce various pipes, plastic doors and windows and so on; even machinery industry, aerospace industry, agricultural production and so on all kinds of all-encompassing products. [0003] For many products, the functionality of masterbatches is critical. Products with intelligent temperature adjustment functions, such as temperature adjustment fibers and temperature adjustment seats, are new products that have emerged...
