A premix of plastic additives

Abstract

The invention relates to a plastic additive premix, which mainly includes epoxy resin and polymer functional filler, and the polymer functional filler is composed of polypropylene and conductive filler. The present invention uses polypropylene and conductive fillers as polymer functional fillers, and the plastic additive premix prepared by polypropylene resin and epoxy resin under heterogeneous nucleation has better uniformity, electrical conductivity and rigidity, etc. The mechanical properties have been improved.

Description

Technical field[0001]The present invention relates to a plastic aid premix, and more particularly to an epoxy resin plastic aid premix.Background technique[0002]Epoxy resin is a conventional thermosetting resin, a highly cured crosslinking density, containing more active functional groups on the molecular chain, thereby having excellent adhesion, high tensile strength and Young's modulus, better The thermal stability and chemical resistance, good thermal insulation, and therefore widely applied to adhesives, electronic devices (excellent electrical insulators), laminated industries, packages, coatings, nautical systems and aerospace. . In partial building parts and mine bracket applications, a large amount of charge accumulation has a large risk, which is easy to lead to a major accident.[0003]Carbon nanotubes serve as one-dimensional nanomaterials with excellent physical mechanical properties. It has a very large diameter ratio, so it is very excellent in mechanics, electrical, and...

Problems solved by technology

However, the dispersion of one-dimensional carbon nanotubes in the resin matrix is ​​not good, and it is easy to form agglomerations and affect the comprehensive performance of composite materials.

Iodine, as a typical halogen element in VIIA, is one of the basic mineral nutrients in life. It has good biocompatibility and non-toxic properties. It is rich in marine resources and low in cost, but the conductivity of elemental iodine is low, and iodine It is easy to dissolve in some organic solvents, which greatly affects its use as a filler in conductive ingredients

[0004] In view of the above problems, the present invention studies a plastic additive premix, which effectively solves the problem of uneven dispersion of carbon nanotubes in the resin matrix, and forms a conductive path through one-dimensional carbon nanotubes and porous carbon@iodine composite materials Network, the addition of polymer functional fillers greatly improves the mechanical properties of epoxy resin
