▎ 摘  要

NOVELTY - Wall repairing waterproof glue comprises 20-40 pts. wt. polyvinyl alcohol, 0.5-2.5 pts. wt. graphene, 15-25 pts. wt. ethylene-vinyl acetate (EVA) foam rubber, 8-17 pts. wt. bamboo charcoal fiber, 12-18 pts. wt. modified attapulgite clay, 6-13 pts. wt. diatom mud, 8-15 pts. wt. fly ash, 7-12 pts. wt. glass beads, 5-10 pts. wt. quartz powder, 4-8 pts. wt. water reducing agent, 2-6 pts. wt. curing agent and 3-5 pts. wt. expanding agent. The modified attapulgite clay is product obtained by purifying the natural attapulgite clay and modifying the alkaline solution. USE - Used as wall repairing waterproof glue. ADVANTAGE - The glue: has excellent bonding property and excellent water resistance; extends the life of the building; is safe and environmentally friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the wall repairing waterproof glue, comprising (i) taking polyvinyl alcohol, adding EVA foam rubber into the reaction kettle, adding 6-7 times of water into the mixed component, stirring uniformly, heating at 70-80 degrees C, adding graphene into the reaction kettle, reacting at constant temperature for 2-3 hours to obtain product a1, (ii) adding bamboo charcoal fiber and modified attapulgite clay into the reaction vessel, and continuously reacting at constant temperature for 20-30 minutes to obtain product a2, (iii) adding the diatom mud, fly ash, glass beads and quartz powder into the reaction kettle and stirring for 30-40 minutes under ultrasonic conditions, adding water reducing agent, curing agent and expanding agent, and mixing uniformly to obtain waterproof glue.
