Preparation methods of amino triazine derivative macromolecular char forming agent and polypropylene flame retardant

Abstract

The invention relates to preparation methods for an amino triazine derivative macromolecular char forming agent and a polypropylene flame retardant. Cyanuric chloride and a solvent are added into a reaction kettle, and alkylamine-containing mixed amine and an acid-binding agent are added dropwise to generate a unitary substituendum; diamine and the acid-binding agent are added dropwise at room temperature to generate a binary substituendum; the amino triazine derivative macromolecular char forming agent is obtained by subsequent treatment, the flame retardant is prepared from the char forming agent, and the flame retardant is high in compatibility in a PP (propene polymer). The preparation methods have the advantages that hydramine is replaced or partially replaced with alkylamine, so that the compatibility of the triazine char forming agent and the PP is improved, and the problem of difficult separation of the triazine char forming agent is solved; with adoption of the non-acetone solvent, the problem of discoloration of the triazine carbonizing agent is solved; the amino triazine derivative macromolecular char forming agent and the polypropylene flame retardant are widely applied to the flame-retardant fields of automobiles, household appliances, building materials and the like.

Description

technical field

[0001] The invention relates to a preparation method of a char-forming agent and a flame retardant, in particular to an aminotriazine derivative char-forming agent and a preparation method of a flame retardant prepared using the same as a raw material. Background technique

[0002] Intumescent flame retardant is one of the types of flame retardants widely used in recent years. This flame retardant overcomes the fact that halogenated flame retardants are easy to emit irritating and corrosive gases and smoke when burning, pollute the environment, and endanger human health. , while corroding equipment and other shortcomings, it is a very promising green and environmentally friendly flame retardant.

[0003] Intumescent flame retardant consists of acid source, carbon source and gas source:

[0004] (1) Acid source: a compound that can release inorganic acid under heating conditions to promote the dehydration and carbonization of polyhydroxy compounds;
