Title:
二峰性の加熱減量分解特徴を有する亜リン酸アルミニウムベースの複合体並びにその調製及び適用
Document Type and Number:
Japanese Patent JP7288285
Kind Code:
B2
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: ((HPO3)3Al2) · ((H2PO3)3Al )x, wherein x is 0.01-0.5 and represents a molar ratio of (H2PO3)3Al to (HPO3)3Al2. 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.
