▎ 摘 要
NOVELTY - Modifying agent comprises 30-70 wt.% phosphoric acid, 1-3 wt.% hydrochloric acid, 1-2.2 wt.% tributyl phosphate, 1-3 wt.% trifluorosilane, 0.1-0.5 wt.% graphene, 0.01-0.1 wt.% hydroxypropyl methylcellulose, and deionized water (remaining amount). USE - The modifying agent is useful preparing magnesium oxychloride composite material (claimed) and for manufacturing plastic mold. ADVANTAGE - The modifying agent improves the weather resistance of magnesium oxychloride material, bad radiating performance, and easy to be affected by physical heat. The product can keep stable state for a long time, without cracking and anti-halogenation. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a magnesium oxychloride composite material; and preparing the magnesium oxychloride composite material.
