Aluminium phosphite-based composite having bimodal thermal weight-loss decomposition characteristics, preparation thereof and use thereof |
| abstract |
The present disclosure provides an aluminum phosphite-based complex with dual-peak thermal gravity decomposition characteristics and a preparation method and use thereof. A structural formula of the complex is as follows: ((HPO<sub>3</sub>)<sub>3</sub>Al<sub>2</sub>) · ((H<sub>2</sub>PO<sub>3</sub>)<sub>3</sub>Al )<sub>x</sub>, wherein x is 0.01-0.5 and represents a molar ratio of (H<sub>2</sub>PO<sub>3</sub>)<sub>3</sub>Al to (HPO<sub>3</sub>)<sub>3</sub>Al<sub>2</sub>. The dual-peak thermal gravity decomposition characteristics are as follows: a first gravity peak temperature is 460-490°C, and a second gravity peak temperature is 550-580°C. The preparation method includes: uniformly mixing aluminum phosphite and aluminum hydrogen phosphite according to the ratio in the structural formula, and then performing stepwise heating at a rate of 5°C/min to raise the temperature of a mixture from the normal temperature to no more than 350°C within 1-10 hours, so as to obtain the aluminum phosphite-based complex with the dual-peak thermal gravity decomposition characteristics. The complex may serve as or is configured to prepare a flame retardant or a flame-retardant synergist. |
