▎ 摘  要

NOVELTY - A grave protective material comprises an inner anti-corrosion material layer, a waterproof material layer, and an outer anti-corrosion material layer that are sequentially coated and hot pressed along the direction away from the grave wall. The inner anti-corrosion material layer includes 10-30 pts. wt. acrylic acid epoxy paint, 1 pt. wt. curing agent, 6-12 pts. wt. glass fiber, and 3-4 pts. wt. thinner. The waterproof material layer includes 1-4 pts. wt. active calcium carbonate with particle size of 5-7.5 microns, and 1-3 pts. wt. fluorine-containing resin. The outer anti-corrosion material layer includes 20-40 pts. wt. asphalt, 1-2 pts. wt. high temperature silver paint, and 3-4 pts. wt. thinner. USE - Grave protective material. ADVANTAGE - The protective material prevents corrosion and dampness of the grave. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the grave protective material, which involves preparing inner layer of anti-corrosion material, waterproof material and outer layer of anti-corrosion material, and coating and hot pressing on the grave wall. The inner anti-corrosion material layer is prepared by mixing acrylic acid epoxy paint, curing agent and glass fiber to obtain a powdery mixture, adding thinner, mixing and stirring to form an inner layer paint, evenly brushing or spraying the inner layer paint on the grave wall, adjusting the temperature of a high-temperature spray gun to 150 plus minus 10 degrees C, continuously spraying and baking for 30 minutes, and naturally cooling. The waterproof material layer is prepared by mixing activated calcium carbonate and fluorine-containing resin to obtain a powdery mixture, adding thinner, mixing and stirring to obtain a waterproof paint, evenly brushing or spraying the waterproof paint on the inner anti-corrosion material layer, adjusting the temperature of the high-temperature spray gun to 170 plus minus 10 degrees C, continuously spraying and baking for 45 minutes, and naturally cooling. The outer anti-corrosion material layer is prepared by mixing asphalt and high-temperature silver paint to form a powdery mixture, adding thinner, mixing and stirring to form an outer layer paint, evenly brushing or spraying the outer layer paint on the waterproof material layer, adjusting the temperature of the high-temperature spray gun to 150 plus minus 10 degrees C, continuously spraying and baking for 30 minutes, and naturally cooling.
