example 1

[0023] According to the mass ratio of 1:20, the waste goose feather and the hydrochloric acid with a mass fraction of 30% were mixed, soaked at 60°C for 3 hours, and the filter residue was obtained by filtering and separating. The filter residue and the sodium bisulfite solution with a mass fraction of 30% were After mixing at 1:20, continue soaking at 60°C for 3 hours, filter and separate to obtain a filter cake; mix the filter cake with 15% sodium hydroxide solution at a mass ratio of 1:10, and put it into a microwave oscillator. At 70°C, react with microwave oscillation at 200W power for 1 hour. After the reaction, filter and remove the reaction residue to obtain the reaction filtrate; put the reaction filtrate into a beaker, and adjust the pH of the above reaction filtrate to neutral with hydrochloric acid with a concentration of 1mol / L. Obtain the pretreatment filtrate, continue to add the concentration of pretreatment filtrate mass 10% in the beaker and be 1mol / L potassiu...

[0025]According to the mass ratio of 1:20, the waste goose feather and the hydrochloric acid with a mass fraction of 30% were mixed, soaked at 65°C for 3 hours, and the filter residue was obtained by filtering and separating. The filter residue and the sodium bisulfite solution with a mass fraction of 30% were After mixing at 1:20, continue soaking at 65°C for 3 hours, filter and separate to obtain a filter cake; mix the filter cake with 15% sodium hydroxide solution at a mass ratio of 1:10, and put it into a microwave oscillator. At 75°C, react with microwave oscillation at a power of 250W for 2 hours. After the reaction, filter and remove the reaction residue to obtain the reaction filtrate; put the reaction filtrate into a beaker, and adjust the pH of the above reaction filtrate to neutral with hydrochloric acid with a concentration of 1mol / L. Obtain the pretreatment filtrate, continue to add the concentration of pretreatment filtrate mass 10% in the beaker and be 1mol / L pot...

[0027] According to the mass ratio of 1:20, mix waste goose feathers with hydrochloric acid with a mass fraction of 30%, soak at 70°C for 4 hours, and filter and separate to obtain a filter residue. After mixing at 1:20, continue soaking at 70°C for 4 hours, filter and separate to obtain the filter cake; mix the filter cake and sodium hydroxide solution with a mass fraction of 15% at a mass ratio of 1:10 and put it into a microwave oscillator. At 80°C, react with microwave oscillation at a power of 300W for 2 hours. After the reaction, filter and separate and remove the reaction filter residue to obtain the reaction filtrate; put the reaction filtrate into a beaker, and adjust the pH of the above reaction filtrate to neutral with hydrochloric acid with a concentration of 1mol / L. Obtain pretreatment filtrate, continue to add the concentration of pretreatment filtrate mass 10% in the beaker and be 1mol / L potassium chloride solution, stir and react at 70 ℃ for 30min, obtain reacti...

Abstract

The invention relates to a method for preparing an anti-freeze environment-friendly brick and belongs to the technical field of building material preparation. The method comprises the steps of carrying out acid leaching and sodium sulfite solution soaking on raw material waste goose feathers to partially open disulfide bonds in goose feather proteins, thereby improving the solubility of the goosefeather proteins; dissolving the goose feather proteins by using an alkali solution; precipitating the proteins by using an acid solution; mixing the obtained proteins with a potassium chloride solution; forming bridge bonds by utilizing carboxyl groups on the goose feather proteins and potassium salt ions to obtain a salt ion-doped goose feather protein product; mixing the salt ion-doped goose feather protein product with other brick materials to form slurry; drying and solidifying after injection molding to obtain a green brick; depositing a layer of orthosilicic acid on the surface of the green brick; and calcining at a high temperature to obtain the anti-freeze environment-friendly brick. The anti-freeze environment-friendly brick prepared by adopting the method disclosed by the invention is excellent in anti-freeze performance and has a broad application prospect.

Description

technical field [0001] The invention relates to a method for preparing frost-resistant environmental protection bricks, which belongs to the technical field of building material preparation. Background technique [0002] At present, my country's building wall materials have always been clay bricks. The production of clay bricks not only destroys a lot of fertile land and consumes a lot of energy, but also is not conducive to environmental governance and the development of the construction industry. Therefore, building wall materials Gradually change from clay bricks to environmentally friendly bricks. Environmentally friendly bricks have high strength, good durability, standard size, complete shape, uniform color, and a simple and natural appearance. They can be used as clear water walls or as any external decoration, but environmentally friendly bricks also have defects. The frost resistance of environmentally friendly bricks is an important factor affecting the durability ...
