▎ 摘　　要

NOVELTY - Paint additive comprises 1 wt.% graphene oxide aqueous solution, 4-5 pts. wt. titanium source, 8-12 pts. wt. silicon source, 3-5 pts. wt. template agent, and 130-150 pts. wt. distilled water. USE - Paint additive used for painting interior and exterior of building (claimed). ADVANTAGE - The paint additive improves the absorbtion ability of formaldehyde and organic pollutant, degradation efficiency, is hydrophobic in nature due to graphene addition, which is good for the surface arrangement. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing paint additive, which involves: (A) adding 5-10 pts. wt. 1 wt.% graphene oxide solution into 130-150 pts. wt. distilled water, and adding titanium source slowly dropwise under stirring, then mixing with aqueous template solution and 1-2 M hydrochloric acid at 30-40 degrees C for 2-3 hours under stirring to obtain mixture; (B) adding 8-9 pts. wt. silicon source dropwise, and reacting the mixture at 30-40 degrees C for 15-24 hours after dripping, and subjecting to aging for 20-48 hours and increasing the temperature to 80-120 degrees C to obtain black mixture; (C) filtering obtained black mixture and drying at 60-100 degrees C for 5-10 hours to obtain dark gray solid material; and (D) calcinating obtained dark gray solid material at 500 degrees C for 5-10 hours under protection of inert gas for removing the templating agent and obtaining the desired product.
