However, PP is an extremely flammable material, and the char formation rate is almost 0, and it is easy to melt and drip, which limits the application field of PP.
Nowadays, halogenated flame retardants are the most widely used in PP, which have high flame retardant performance and high overall cost performance. After the restriction on halogenated flame retardants was issued, it cast a shadow over the prospects of halogenated flame retardants

Abstract
The invention relates to a halogen-free polyolefin flame retardation charring agent compound and a preparation method thereof. The structure of the compound is represented by formula shown in the description; and in the formula, n is greater than 1, X is alcohol amine, and Y is dialkylamine. The preparation method comprises the following steps: adding equimolar alcohol amine to a triglycidyl isocyanurate solution while stirring, heating the obtained solution to a certain temperature, and carrying out a heat insulation reaction for a period of time to make the pH value of the solution be 7-8; and adding a certain mole of dialkylamine, heating the obtained solution to a certain temperature, carrying out a heat insulation reaction for a period of time to make the pH value of the solution be 7-8, cooling the solution, carrying out suction filtration (solvent recycling), washing the obtained material with water, drying the washed material, and crushing the dried material to obtain the halogen-free polyolefin flame retardation charring agent. The halogen-free polyolefin flame retardation charring agent is an excellent flame-retardation charring agent, has a charring anti-drip effect, has good compatibility with high-molecular materials, has good heatproof and waterproof property, has excellent processing properties, and can be used as the flame-retardation charring agent of polyethylene (PE), polypropylene (PP) and silicone rubber; and the preparation method has the advantages of cheap and easily available raw materials, low production cost, less device investment, simple production process, and easy large-scale production.
Description
technical field [0001] The invention relates to a halogen-free polyolefin flame-retardant char-forming agent compound and a preparation method thereof. The compound can be used as a char-forming agent for materials such as polyethylene (PE), polypropylene (PP), and silicon rubber. Background technique [0002] Polypropylene (PP) is a general-purpose plastic that has developed rapidly in recent years. Because of its characteristics of odorless, non-toxic and tasteless, good physical and chemical stability, low density, excellent electrical insulation, and convenient processing, it is used in the automotive industry, household appliances, It is widely used in electronics, wire and cable, packaging and building materials. However, PP is an extremely flammable material, and the char formation rate is almost 0, and it is easy to melt and drip, which limits the application field of PP. Nowadays, halogenated flame retardants are the most widely used in PP, which have high flame re...
