Example Embodiment

[0019] Example 1

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

[0021] Example 2

[0022] Weigh 75g of gypsum rock into a pulverizer, grind and smash for 89 minutes, pass through a 100-mesh sieve, collect the sieved powder, put the sieved powder into a muffle furnace, calcined at a temperature of 280℃ for 1.5h, and cool to room temperature naturally The calcined gypsum was obtained. The calcined gypsum and the 32% silver nitrate solution were mixed in a beaker and stirred for 7 minutes at a mass ratio of 1:3 to obtain a stirring solution, and the pH of the stirring solution was adjusted with a 12% mass fraction of nitric acid solution After reaching 7, put the stirring solution in a dull greenhouse and mix and stir for 55 minutes, then vacuum filter, remove the filtrate, take out the filter residue, continue to put the filter residue in the oven, and dry it at 80°C for 25 minutes. Obtain self-made silver-loaded gypsum; weigh 55g of nanometer titanium dioxide and pour it into the kiln, activate it at 180℃ for 14min to obtain activated nanomete...

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....
