Abstract

The invention discloses a hybridized grafted flame-retarding epoxy material. The hybridized grafted flame-retarding epoxy material is prepared from the following raw materials in parts by weight: 6 to 8 parts of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, 1 to 2 parts of vinyltrimethoxysilane, 0.1 to 0.2 part of 2,2'-azobisisobutyronitrile, 2 to 3 parts of triglycidyl isocyanurate, a proper amount of dimethylformamide, 0.8 to 2 parts of 3-aminopropyltriethoxysilane, 17 to 20 parts of a 10% to 13% hydrochloric acid solution, 5 to 8 parts of methylhexahydrophthalic anhydride, 100 to 120 parts of epoxy resin E40 and a proper amount of ethanol. The epoxy material disclosed by the invention has very good flame-retarding and fireproof performance, good utilization safety and excellent comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of epoxy materials, in particular to a hybrid grafted flame-retardant epoxy material and a preparation method thereof. Background technique [0002] Polymer-inorganic composites have attracted widespread attention due to their excellent thermal stability, oxidation resistance, mechanical properties, and hardness. The incompatibility between the polymer matrix and the inorganic phase is a challenge to obtain composites with excellent properties. Therefore, enhancing the interfacial interaction between the inorganic substance and the polymer matrix to improve the dispersion of the inorganic substance is the key to solving the problem. The sol-gel method is a commonly used method for preparing organic-inorganic hybrid materials. The different silane precursors and sol-gel conditions in the sol-gel process endow the sol-gel method with great flexibility. Through the sol-gel process, the inorganic phase can be ...
