example 1

[0020] Weigh 65g of gypsum rock, put it into a pulverizer, grind and pulverize it for 7 minutes, pass it through a 100-mesh sieve, collect the sieved powder, put the sifted powder into a muffle furnace, calcinate at a temperature of 240°C for 1 hour, and cool naturally to room temperature to obtain For calcined gypsum, mix calcined gypsum and silver nitrate solution with a mass fraction of 32% in a beaker and stir for 6 minutes according to a mass ratio of 1:3 to obtain a stirred liquid, and adjust the pH of the stirred liquid with a mass fraction of 12% nitric acid solution to 6. Put the stirring solution in a dark greenhouse and mix and stir for 45 minutes, filter under reduced pressure, remove the filtrate, take out the filter residue, continue to put the filter residue in an oven, and dry it for 20 minutes at a temperature of 70°C to obtain Self-made silver-loaded gypsum; weigh 65g of nano-titanium dioxide and pour it into a kiln, activate it at 200°C for 16 minutes to obta...

[0022]Weigh 75g of gypsum rock, put it into a pulverizer, grind and pulverize it for 89min, pass through a 100-mesh sieve, collect the sieved powder, put the sifted powder into a muffle furnace, calcinate at a temperature of 280°C for 1.5h, and cool naturally to room temperature. To obtain calcined gypsum, mix calcined gypsum and silver nitrate solution with a mass fraction of 32% in a beaker and stir for 7 minutes according to a mass ratio of 1:3 to obtain a stirred solution, and adjust the pH of the stirred solution with a 12% nitric acid solution to 7, then put the stirring solution in a dark greenhouse and mix and stir for 55 minutes, then filter under reduced pressure, remove the filtrate, take out the filter residue, continue to put the filter residue in an oven, and dry it for 25 minutes at a temperature of 80°C. Obtain self-made silver-loaded gypsum; weigh 55g of nano-titanium dioxide and pour it into a kiln, activate it at 180°C for 14 minutes to obtain activated nano-...

Abstract

The invention discloses a method for preparing a waterproof antibacterial ceiling material and belongs to the technical field of plate preparation. Gypsum of a porous structure is modified by a silvernitrate solution, and bacteria are killed by utilizing a catalytic reaction, so that the sterilization efficiency is increased. After combination of the catalytic reaction, silver ions are effectively filled in pores of the gypsum, so that the material has a certain hardness. Since superoxide anion radicals and hydroxyl radicals with extremely high chemical activity are produced during illumination, organic matters in bacterial cells are degraded. Lignin sulfonate, calcium oxalate, water-borne silicone and peach gum are added into the ingredients, the lignin sulfonate has an excellent water reducing function, and due to the extremely small doping amount, the water usage of gypsum slurry can be reduced; and due to the admixture ratio, the gypsum slurry crystallization process is regulated,the porosity of the gypsum hardened body is reduced, the adsorption property of the gypsum hardened body to water is reduced, the waterproof performance and strength of the ceiling material are further improved, and the waterproof antibacterial ceiling material has wide application prospects.

Description

technical field [0001] The invention discloses a preparation method of a waterproof antibacterial ceiling material, which belongs to the technical field of plate preparation. Background technique [0002] A ceiling is the top surface of a building's interior. In interior design, the ceiling can be painted and painted to beautify the indoor environment, as well as install chandeliers, light pipes, ceiling fans, open skylights, install air conditioners, and change the effectiveness of indoor lighting and air circulation. Ceiling is a general term for decorative interior roofing materials. In the past, traditional dwellings mostly used straw mats, reed mats, and wooden boards as the main materials. With the advancement of science and technology, more modern building materials have been applied. Ceilings are generally divided into the following types: gypsum ceilings are made of plaster of Paris as the main raw material mixed with additives and fibers. crack and deformation....
