Hybrid grafted oxidation-resistant and flame-retardant epoxy material and preparation method thereof

Abstract

The invention discloses a hybrid grafted oxidation-resistant and flame-retardant epoxy material. The material is prepared from raw materials in parts by weight as follows: 3-4 parts of ammonium polyphosphate, 6-8 parts of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, 1-2 parts of vinyl trimethoxy silane, 0.1-0.2 parts of azobisisobutyronitrile, 2-3 parts of triglycidyl isocyanurate, a proper amount of dimethylformamide, 0.8-2 parts of 3-amino propyl triethoxysilane, 17-20 parts of a 10%-13% hydrochloric acid solution, 5-8 parts of methyl hexahydrophthalic anhydride, 100-120 parts of epoxy resin E40, 3-4 parts of dioctyl sebacate, 0.8-1 part of diisocyanate, 1-2 parts of diacetone acrylamide, a proper amount of ethanol, 0.4-1 part of tert-butyl hydroquinone, 3-5 parts of diniconazole, 2-3 parts of sodium myrastate and 1-2 parts of calcium borate. The added tert-butyl hydroquinone and the like can effectively improve the oxidation resistance of the finished material and improve the storage stability of the finished product.

Description

technical field [0001] The invention relates to the technical field of epoxy materials, in particular to a hybrid grafted anti-oxidation and 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 inor...
