Problems solved by technology

From the perspective of resource protection, the first treatment method is the best. However, due to the relatively backward recycling technology of waste glass in my country, most of the waste glass is simply piled up and landfilled as waste.
Waste glass is a non-degradable material, and landfilling it is not a good solution

Embodiment 1

[0032] 1. Weigh the powder (alumina powder with an average particle size of 0.2um and glass powder with an average particle size of 2.5um at a mass ratio of 1:1), and then press the mass ratio of powder and water in a ball mill jar Add deionized water at a ratio of 2.7:1, and adjust the pH of the solvent water to about 2 with an acid-base regulator. Add the above-mentioned weighed powder into the solvent spoon by spoon, stir while adding, after stirring evenly, under the state of rapid stirring (300r / min), add propionic acid and polyvinyl alcohol (the addition of propionic acid is according to each g powder is calculated by adding 0.04mmol propionic acid, and the amount of polyvinyl alcohol is calculated according to 1wt% of the powder mass), after stirring for 5-10min, add n-octane in an amount of oil-water volume ratio of 2:1, and grind The mass ratio of the ball to the ceramic powder is 1:1, adding alumina grinding balls. The speed of the ball mill is 300r / min. After ball ...

[0039] 1. Weigh the powder (alumina powder with an average particle size of 0.4um and glass powder with an average particle size of 2.5um at a mass ratio of 1:2), and then press the mass ratio of powder and water in a ball mill jar Add deionized water at a ratio of 1:1, and adjust the pH of the solvent water to 2 with an acid-base regulator. Add the above-mentioned weighed powder into the solvent one by one, stir while adding, after stirring evenly, under the state of rapid stirring (about 300r / min), add propionic acid and polyvinyl alcohol (the addition of propionic acid is according to Add 0.08mmol propionic acid per gram of powder, the amount of polyvinyl alcohol added is based on 2wt% of the powder mass), after stirring for 5-10min, add n-octane according to the oil-water volume ratio of 1:1, Add alumina grinding balls according to the mass ratio of grinding balls and ceramic powder at 1:1. The speed of the ball mill is 350r / min. After 12 hours of ball milling, inject the...

Embodiment 3

[0043] 1. Weigh the powder (alumina powder with an average particle size of 0.2um and glass powder with an average particle size of 2.5um at a mass ratio of 2:1), and then press the powder to water mass ratio in a ball mill jar Add deionized water at a ratio of 2:1, and adjust the pH of the solvent water to 2 with an acid-base regulator. The above-mentioned powders weighed are added into the solvent one by one spoonfuls, and stirred while adding, after stirring evenly, under the state of rapid stirring (300r / min), add valeric acid and polyethylene glycol (the addition of valeric acid is according to Add 0.08mmol propionic acid per gram of powder, the amount of polyethylene glycol added is calculated according to 2wt% of the powder mass), after stirring for 5-10min, add hexadecane at an oil-water volume ratio of 1:1 alkanes, according to the mass ratio of grinding balls and ceramic powder 1:1, add alumina grinding balls. The speed of the ball mill is 350r / min. After 12 hours o...

Abstract

The invention belongs to the technical field of inorganic non-metallic materials, and discloses self-cleaning light-weight high-strength porous ceramic taking waste glass as a raw material as well asa preparation method and application of the self-cleaning light-weight high-strength porous ceramic. The preparation method comprises the following steps of: performing mixing and ball-milling on ceramic powder, water, an acid-base regulator, organic acid, a surfactant, an organic solvent and glass powder to obtain slurry; performing curing molding, curing, glue discharging and sintering treatmenton the slurry sequentially so as to obtain the light-weight and high-strength porous ceramic material. And arranging a hydrophobic layer on the surface of the ceramic material to obtain the self-cleaning lightweight high-strength porous ceramic material. Micro pores are introduced into the ceramic by using an emulsion template method, and meanwhile, the surface of the ceramic is modified with organic silicon, so that the integration of the functions of light weight, high strength, self-cleaning and the like of the ceramic material is realized; in addition, the problem that an existing waste glass recycling technology is difficult can be effectively solved, the waste recycling rate is increased, and therefore preparation of the multifunctional porous ceramic material has remarkable economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of inorganic non-metallic materials, and in particular relates to a self-cleaning light-weight and high-strength porous ceramic using waste glass as a raw material and a preparation method and application thereof. Background technique [0002] With the development of industry and other industries, glass materials are used more and more widely, more and more waste glass powder is produced in the production process, and a lot of glass waste is also produced in life, which not only pollutes the environment, Moreover, it takes up valuable land resources and increases the environmental load. Recycling glass waste and making waste glass a valuable resource to produce products that people need has aroused great concern from the society. At present, there are mainly three disposal methods for waste glass: ①Recycle as raw material for reproducing glass; ②Use as raw material for secondary products; ③Fill and bury to ...
