Problems solved by technology

[0002] Traditional halogen-containing flame retardants have the advantages of good flame-retardant effect, less addition, and little impact on the mechanical properties of organic matter, and are widely used in the flame retardancy of polymer materials. When burning, a large amount of smoke and toxic gases such as hydrogen halide are released, resulting in secondary pollution, and the adverse effects on the environment and human life are becoming more and more significant, thus forcing governments and organizations of various countries to propose restrictive measures for the use of halogenated flame retardants

Abstract

The invention provides a flame-retardant material additive and a preparation method thereof, and relates to auxiliary chemicals. The flame-retardant material additive provided by the invention comprises the following components: 2-4% of glacial acetic acid, 4.5-5.5% of benzenetetracarboxylic anhydride, 9-11% of epoxy resin, 4.5-5.5% of a silane coupling agent, 5-7% of silicon dioxide, 3-5% of aluminium oxide and 62-72% of glass fiber cloth powder. The production process of the flame-retardant material additive comprises the following steps: preparing materials; cutting for the first time, and cutting for the second time; drying, crushing, and grinding the materials for the first time; adding auxiliary materials, re-baking, grinding for the second time, and bagging to finally obtain the flame-retardant material additive. The glass fiber cloth waste is taken as a main material, so that the flame-retardant material additive has the advantages of low production cost, good heat stability, excellent flame retardant efficiency and environmental protection property, simple operation process and good application prospect, is not separated out after being blended with a high polymer material, is small in influence on the mechanical properties of the materials, and is capable of achieving industrial production.
