Abstract

The invention provides a polymer structure composite material and a preparation method thereof: the mass concentration of the filler in the polymer structure composite material in the polymer matrix is ​​0.1-20 ppm; the filler is graphene, silicon dioxide, carbon nanometer At least one of tubes, carbon black, aluminum oxide, zinc oxide, calcium carbonate, titanium dioxide, talc, and montmorillonite, and the polymer matrix is ​​at least one of epoxy resins and unsaturated resins; the preparation method is as follows : First mix the filler with an appropriate amount of polymer matrix to form a master batch. When there is epoxy resin in the polymer matrix, a polymer medium needs to be added to reduce the viscosity of the polymer matrix; take an appropriate amount of masterbatch, press The mass concentration ratio of the filler in the polymer matrix The masterbatch is diluted into the polymer matrix and mixed evenly to obtain the polymer structure composite material. The polymer structure composite material of the invention has good monodispersity and high mechanical properties; the preparation method is simple and easy to operate, and is easy to be used for industrialized mass production.

Description

[0001] 【Technical field】 [0002] The invention relates to a polymer structure composite material and a preparation method thereof. [0003] 【Background technique】 [0004] Thermosetting resins are a class of polymers with a three-dimensional network structure, usually formed from oligomers or low-molecular compounds containing two or more active functional groups in their molecules through curing and cross-linking reactions in the presence of cross-linking agents or catalysts. Thermosetting resin monomers or prepolymers have excellent flow processing properties, and the cured network structure makes them have excellent physical and mechanical properties, electrical insulation properties, chemical resistance, bonding properties and thermal stability. , Thermosetting resins are widely used in the technical fields of machinery, electronics, aerospace and other fields in the form of adhesives, coatings, potting materials and composite materials. However, due to the high crosslink...
