▎ 摘  要

NOVELTY - A composite board core material comprises 10-16 pts. wt. aqueous epoxy resin, 6-12 pts. wt. porous graphene, 2-5 pts. wt. nano calcium carbonate powder, 5-10 pts. wt. aqueous polyurethane, 0.4-1.2 pts. wt. dispersant, 1.5-4 pts. wt. coupling agent, 0.1-0.6 pt. wt. water reducing agent, 0.5-1.5 pts. wt. foaming agent and 30-45 pts. wt. construction waste. USE - Composite board core material (claimed). ADVANTAGE - The composite board core material has excellent strength, and is environmentally-friendly. The core material can be prepared industrially with high yield by simple method. The recycling of waste resources is enabled. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite board core material.
