▎ 摘  要

NOVELTY - Frost inhibiting enhancing agent comprises 20-25 pts. wt. acrylic monomer, 20-25 pts. wt. acrylate monomer, 4-6 pts. wt. cationic monomer, 2-4 pts. wt. emulsifier, 10-15 pts. wt. sodium hydroxide solution (30%), 20-30 pts. wt. graphene oxide sheet layer suspension, 30-40 pts. wt. initiator aqueous solution and 180-250 pts. wt. deionized water. USE - The frost inhibiting enhancing agent is useful for cement bricks (claimed). ADVANTAGE - The frost inhibiting enhancing agent accelerates the speed of hydration reaction of cement, inhibits cement brick immigration of the alkaline substance that cause the saltpetering phenomenon, increases early strength and later period strengthening of cement level grounds. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for frost inhibiting enhancing agent, comprising adding 150-200 pts. wt. deoinized water and graphene oxide sheet layer suspension into reactor, heating to 80-90 degrees C, simultaneously dripping acrylic monomer, acrylic ester monomer, cationic monomer, 40-50 pts. wt. deionized water, sodium hydroxide solution (30%), emulsifier, mixed monomer and initiator aqueous solution, adding material time is 30-40 minutes, adding material after completing heat insulating temperature reacting for 2-5 hours, reducing temperature to 30-40 degrees C, using quality fraction sodium hydroxide solution (30%) adjusting product pH to 6-7, controlling solid content of product at 18-22% to obtain frost inhibiting enhancing agent.
