[0040] see figure 1 , the present invention provides a technical solution: a wood and bamboo flame retardant and a preparation method thereof,
[0041] Relevant chemical mechanism of the present invention is:
[0042] (1) Benzomelamine is rich in primary amines. By utilizing the char formation and thermal stability of the benzomelamine structure and the characteristics of nitrogen-phosphorus conjugate synergistic flame retardancy, better char formation rate and flame retardancy can be obtained. The flame retardant, the material containing the flame retardant is more likely to form a dense carbon layer during combustion, thereby isolating the contact between oxygen and the internal material to achieve the flame retardant effect.
[0043] (2) Nitrogen-phosphorus-boron conjugated synergistic flame retardant, the steric hindrance in the structure of the flame retardant is large, which is conducive to improving the flame retardant effect; in addition, benzomelamine also has the ef...
Embodiment 1
[0052] Provided is a multifunctional wood and bamboo flame retardant and a preparation method thereof, comprising the following components in parts by weight: 35 parts of a main agent, 5 parts of a smoke suppressant, 6 parts of an antibacterial and aldehyde removal agent, and a synergistic effect of flame retardant and aldehyde removal 15 parts of agent, 8 parts of char-forming accelerator, and 90 parts of deionized water are mixed.
[0053] The main agent, smoke suppressant, antibacterial formaldehyde removal agent, flame retardant formaldehyde removal synergist, and char formation accelerator are prepared by the following methods:
[0054] 1. Main agent of flame retardant: under the protection of nitrogen, add appropriate amount of benzomelamine and deionized water into the reaction kettle with stirring device, raise the temperature to 90°C and stir to obtain a completely dissolved benzomelamine solution. The molar ratio of benzomelamine to deionized water is 1:25. Then dro...
