▎ 摘  要

NOVELTY - A building insulation gypsum powder with sound-absorbing noise-reducing function comprises 45-47 pts. wt. natural gypsum, 48-50 pts. wt. phosphogypsum, 16-17 pts. wt. calcined alunite, 3.2-3.5 pts. wt. hydroxyethyl cellulose, 1.6-1.8 pts. wt. graphene, 9-12 pts. wt. waste plastic particles, 7-9 pts. wt. white mineral oil, 10-11 pts. wt. fluff pulp, 2.3-2.5 pts. wt. stearic acid, 0.4-0.5 pts. wt. ammonium nitrate, 15-17 pts. wt. chestnut shell powder, 0.02-0.03 pts. wt. nano-aluminum powder and appropriate amount of water. USE - Building insulation gypsum powder with sound-absorbing noise-reducing function used for processing paper gypsum board, building block and building plaster. ADVANTAGE - The building insulation gypsum powder is economical and has high strength, large porosity, high heat preservation effect, sound-absorbing noise reduction effect, high performance, high bond strength, high compressive and high flexural strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of building insulation gypsum powder with sound-absorbing noise-reducing function.
