specific Embodiment approach 1

[0015] Specific embodiment 1: The general structure of the triazine-based oligomer of this embodiment is:

[0016] Where: m 1 =0 or 1, m 2 = 1 or 2; R = (CH 2 ) n1 , N1=1~6; X means NHR 1 NH or Or Where R 1 =(CH 2 ) n2 Or benzene ring, n2=2~6; Y represents piperazine or Or m=1-15.

specific Embodiment approach 2

[0017] Embodiment 2: The steps of the method for synthesizing triazine-based oligomers in this embodiment are as follows: a. Using cyanuric chloride as a starting material and inorganic base as an acid binding agent, adding cyanuric chloride into a reaction vessel, Add solvent to the reaction vessel to make cyanuric chloride evenly dispersed. Add alcoholamine and acid binding agent dropwise to the reaction vessel under the condition of 0~10℃ to control the dropping rate of acid binding agent to control the pH value of the solution. After 5~7, after 2~4 hours of reaction, when the pH value of the reaction solution is close to neutral, the first step substitution reaction is over, and the monosubstituted cyanuric chloride 2-hydroxyalkylamino-4,6-dichloride is produced. -1,3,5-triazine, in which the ratio of cyanuric chloride and alcohol amine is 1:1; b. Raise the temperature to 40-70°C, and add dropwise the two used in the second step of the substitution reaction. The pH value of am...

specific Embodiment approach 3

[0019] Embodiment 3: In this embodiment, in step one, the solvent is acetone, water or a mixture of acetone and water. Others are the same as the second embodiment.

[0020] In this embodiment, when the solvent is a mixture, acetone and water are mixed in an arbitrary ratio.

Abstract

The invention relates to a triazine series oligomer and the compound method. The method has the following steps: adding solvent into cyanuric chloride, dropping alkylol amine and acid roping agent to gain substitute of cyanuric chloride; heating, dropping diamidogen and acid roping agent to gain the substitute of cyanuric chloride; adding diamidogen and acid roping agent into reaction solution, heating, pumping, washing, and drying to gain triazine series oligomer. The invention has strong charring and expanding ability, and good thermal stability. It has advantages of continuously reaction process, short reaction time, simple compounding technology, little organic solvent, and easy to recycle organic solvent.

Description

Technical field [0001] The invention belongs to the field of organic chemistry, and specifically relates to a triazine derivative and a synthesis method thereof. Background technique [0002] Intumescent flame retardant (IFR) is a halogen-free flame retardant with phosphorus and nitrogen as the main components. When the polymer containing IFR is heated and burned, a uniform carbon foam layer can be formed on the surface. The carbon layer in the condensed phase can play the role of heat insulation, oxygen insulation, smoke suppression and prevention of droplets, thereby playing a flame retardant effect, and has good resistance to prolonged or repeated exposure to flames. Intumescent flame retardant (IFR) overcomes the shortcomings of halogen-containing flame retardants of large burning smoke and multiple droplets and the adverse effects of inorganic flame retardants on the mechanical and processing properties of materials due to the large amount of addition. It is a kind of A new ...
