Abstract

The invention provides a flame-retardant microcapsule and a preparation method thereof. The flame-retardant microcapsule comprises: a capsule core which is a hydrophilic flame-retardant material; an intermediate layer located at the outer peripheral portion of the capsule core, the intermediate layer being selected from any one of a polymer, an inorganic substance, an organic substance, and an organic-inorganic hybrid material; and an outer layer which is located on the periphery of the intermediate layer, wherein the outer layer is hybrid particles with the surfaces comprising hydrophilic areas and hydrophobic areas, and the hybrid particles show hydrophilicity and hydrophobicity at the same time. The flame-retardant microcapsule is high in coating rate and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of microcapsules, and in particular relates to a flame-retardant microcapsule and a preparation method thereof. Background technique [0002] Polymer materials are widely used in all walks of life in the national economy because of their excellent performance and low price. However, since most polymer materials are flammable materials, and in the process of burning, they have the characteristics of high heat release rate, high calorific value, fast flame propagation rate, not easy to extinguish, and often produce dense smoke and toxic gases. People's life safety and environment cause great harm. [0003] At present, by using flame-retardant materials, they can synergize with polymers during combustion to form a highly expanded dense carbon layer to achieve flame-retardant effects. However, in the process of using flame-retardant materials, most flame-retardant materials, For example, ammonium polyphosphate...
