Abstract

The invention relates to a halogen-free flame retardant composition and application thereof. The halogen-free flame retardant composition at least comprises a component A, a component B, a component Cand a component D, wherein the component A is one or more of 2-carboxyethyl phenyl phosphinates; the component B is one or more of aluminum diethyl phosphinate, zinc diethyl phosphinate, aluminum methyl ethyl phosphinate, aluminum methyl propyl phosphinate, aluminum dipropyl phosphinate and aluminum ethyl propyl phosphinate; the component C is one or more of melamine cyanuric acid, melamine polyphosphate, melamine trithiocyanate, melamine hypophosphite and ammonium polyphosphate; and the component D is one or more of montmorillonite, kaolin, molybdenum disulfide, graphite-like carbon nitride,graphene and graphene oxide. The application process is as follows: resin, fibers and the halogen-free flame retardant composition are subjected to melt blending to prepare flame-retardant polymer materials. The halogen-free flame retardant composition disclosed by the invention is simple to prepare, low in cost, free of halogen elements, lasting in flame-retardant effect, capable of continuouslyretarding flame in the whole stage of flame development and good in application prospect.

Description

technical field [0001] The invention belongs to the technical field of flame retardants, and relates to a halogen-free flame retardant composition and its application. Background technique [0002] A flame retardant is an additive that can impart flammable or non-combustible properties to flammable materials. When the polymer material is burning, it will timely and effectively prevent the flame from spreading and prevent the polymer from continuing to burn by releasing gas or forming a carbon layer, so as to achieve the purpose of preventing combustion. [0003] In order to improve the flame retardant efficiency, the method usually adopted by researchers is flame retardant compounding technology, whose main feature is to combine special elements or special structures in several flame retardants to form a synergistic effect between them, thereby Improve flame retardant properties. However, this common compounding technology also has many disadvantages, such as it can only f...
