Abstract

The invention discloses an additive type phosphorus phenanthrene oxa-flame retardant and a preparation method thereof. The chemical name of the additive type phosphorus phenanthrene oxa-flame retardant is poly-(10-taconic acid gylcol ester-9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide). The preparation method comprises the following steps of: firstly carrying out a reaction on DOPO, itaconic acid and ethylene glycol to generate a monomer midbody 10-taconic acid gylcol ester-9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide; and polymerizing the reacting midbody at high temperature under the function of catalyst to obtain a target product. The additive type phosphorus phenanthrene oxa-flame retardant provided by the invention is applicable to various high molecular materials with higher processing temperature such as linear polyester, fiber, polyamide, polyurethane and the like; and the preparation method is free from halogen, environment-friendly, simple in operation process, easy to control, high in yield, good in product repeatability, and less in impurity, wherein the product yield can be 98.5%-99.9%, and the production cost can be reduced.

Description

technical field

[0001] The invention relates to a flame retardant, in particular to an additive-type phenanthrene-oxa flame retardant and a preparation method thereof. Background technique

[0002] With the rapid rise of polymer material science, polymer materials are widely used in human production and life, and more and more fires are caused by them being ignited. Therefore, the flame retardancy of polymer materials has been widely recognized by people. focus on. Japan and Germany have conducted very in-depth research, and my country has also conducted extensive research in this field, and has also achieved some considerable achievements. Especially with the decrease of bromine resources, phosphorus series flame retardants with relatively good flame retardant properties have been developed rapidly. DOPO and its derivatives can introduce compounds containing flame retardant elements into polymer hosts through copolymerization. Chain, has the characteristics of high flame ...
