Abstract

The invention relates to a macromolecule trazine charring agent and a preparation method thereof. According to the invention, a group with the catalytic action is introduced into a triazine macromolecule polymer with the main chains containing the fatty group structures, and is integrated with the charring agent, so as to generate the catalytic action nearby; or, the group with the catalytic action can also be fixed on molecular chains of the polymer, so as to prevent migration and uneven dispersion and greatly improve catalytic efficiency. The specific preparation method is as follows: firstly, a binary substance and an acid-binding agent are mixed, and then are stirred for 0.5 to 1 hour, so as to obtain a compound with bifunctional reactive hydrogen; the compound is added into a cyanuric chloride aprotic organic solvent to react for 4 to 8 hours, and then is added into an aprotic organic solvent containing sulfonic acid group activated monomers to react for 8 to 12 hours by adding the catalytic agent and the acid-binding agent; and finally, the product is obtained through filtering, washing and drying. The method provided by the invention has continuous reaction process, short reaction time and high reaction efficiency.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a catalytic-char-forming agent, in particular to a macromolecular triazine char-forming agent with a catalytic side chain and a preparation method thereof. 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. Intumescent flame retardants generally consist of three basic components: acid source, carbon source, and gas source. When burning, the "three sources" can be effectively matched to form a non-combustible carbon foam layer with a fluffy and closed structure, which weakens th...
