Problems solved by technology

The present invention aims at the defects of the existing flame retardants that the flame retardant performance decreases due to migration from the matrix, moisture absorption, etc., and provides a polyamide flame retardant containing both ferrocene and triazine ring structures, namely ferrocene- Triazine ring double-base polyamide synergistically forms a charcoal agent. While avoiding the above defects, the polymer also realizes the flame retardancy of polymer materials; Poor effect and low heat resistance

Abstract

The invention discloses a ferrocene-thiotriazinone biradical polyamide synergistic charring agent shown in the formula (I) and a preparation method thereof.The preparation method of the polymer includes the steps that phenol, distilled water, an acid-binding agent I, cyanuric chloride, an organic solvent I and the like serve as raw materials and are prepared into an intermediate I through chemical reaction, the intermediate I, an acid-binding agent II, ammonia water, an organic solvent II and the like are prepared into an intermediate II through chemical reaction, and then the intermediate II, a raw material I, a dehydration agent, organic alkali, an organic solvent III and the like are prepared into the ferrocene-thiotriazinone biradical polyamide synergistic charring agent through chemical reaction.The polyamide synergistic charring agent is a polymerization type flame-retardant agent, can be used for flame retardance of plastic and other organic high polymer materials, can effectively improve heat stability and increase the residual carbon amount of a system, promotes matrix degradation cross-linking charring and compact carbon layer forming, and reduces release of smoke.The preparation method is simple and easy to control, and the polyamide synergistic charring agent is easy to obtain, good in performance and high in practicality.The formula (I) is as shown in the description.

Description

technical field [0001] The invention belongs to organic compounds and their preparation and application, and relates to a ferrocene-triazine ring double base polyamide synergistic charcoal forming agent and its preparation method and application. The ferrocene-triazine ring double base polyamide synergistic charcoal forming agent of the present invention is a flame retardant especially suitable for organic polymer materials such as plastics. Background technique [0002] With the development of the economy and the improvement of living standards, the application of polymer materials in human life has also greatly increased. This type of material is extremely flammable and will release a large amount of toxic gases when burned, which can easily suffocate people and hinder rescue. work in progress. Such as PE, PP, ABS, etc., when they burn, they will emit toxic gases and generate a lot of black smoke, which not only causes property losses, but also greatly threatens people's ...
