Flame Retardant Properties of Fiber-Based Decorative Wallboard

摘要

In this study, bamboo pulp is utilized as the main raw material for the production of compression-molded, fiber-based decorative wallboard panels which have three-dimensional geometric structure and possess environmentally compatible "green" flame retardant properties. The effectiveness of several flame retarding agents, including the Al(OH)_3 single component system, the Al(OH)_3/Mg(OH)_2 mixed system and the Al(OH)_3/Mg(OH)_2/Zinc Borate mixed system are examined in terms of the resulting flame resistance, physical properties and oxygen indexes of the fiber-based decorative wallboard. The results show that the Al(OH)_3/Mg(OH)_2/Zinc Borate roulticomponent mixed system is the most ideal flame retardant system for such applications. Results indicate that the optimal formulation consist of: 30% Mg(OH)_2/25% Al(OH)_2 /15% Zinc borate (relative mass ratio). Under such conditions, the oxygen index of the fiber decorates wallboard is 34.4, and the level of formaldehyde release reaches a value of EO.
