Description

Technical Field

[0001] The invention belongs to the technical field of self-cleaning light-storing ceramics, and in particular relates to a method for preparing solid waste integrated self-cleaning light-storing ceramics with epoxy resin. Background Art

[0002] Photoluminescent ceramics have the "3H" technical characteristics of high brightness, high durability and high tolerance. They do not require laying circuits for installation, can permanently save electricity, and have significant performance advantages. On the basis of overcoming key technical problems, the ceramic production process can be used to achieve mass production, and has a strong potential for recycling solid waste and saving resources. After laying, the principle of photocatalysis is used, and there is no need for staff to sterilize and disinfect, which protects human health and can save a lot of manpower and material resources.

[0003] Photoluminescent spontaneous materials are green light source materials that can store light energy when excited by a light source and slowly release the stored energy in the form of light after the excitation stops. Rare earth aluminate and silicate luminescent materials developed in the last century have the advantages of long luminescence time, high brightness, good stability, and non-toxicity. At present, most of the photoluminescent safety indicator materials at home and abroad are made of plastics, rubbers, paints, etc., which can be fixed at room temperature or relatively low temperature. Compared with these materials, ceramic materials have the advantages of high strength, less environmental impact, long service life, and easy cleaning.

[0004] Therefore, predecessors applied for the following patents in the process of research on photoluminescent ceramics: For example, patent document CN115557779B, application date October 21, 2022, discloses an all-weather self-cleaning photoluminescent ceramic and its preparation method, comprising the following steps: S01: weighing, taking the total mass of the raw material powder as 100%, weighing 40% to 45% of 10-30 mesh quartz raw materials, 35% to 39% of 50-100 mesh quartz raw materials, 5% to 20% of 150-250 mesh quartz raw materials, and the rest are raw material powders of photoluminescent materials; S02: mixing The powder raw material weighed in S01 is placed in a ball mill, and grinding balls and deionized water are added for ball milling and mixing; S03: molding, vacuum degassing the slurry after ball milling in S02, and then injecting the degassing slurry into a mold for molding to obtain a blank; S04: drying, demoulding the blank obtained in S03 after standing for 6 to 13 hours, and then drying it in a drying oven. The ceramic involved in the present invention can achieve air purification and self-cleaning, and the nano-TiO2 solution is evenly sprayed on the surface of the light-storage ceramic by spraying with a sprayer, thereby obtaining a light-storage ceramic with a self-cleaning function. However, in the patent document CN115557779B, the nano-TiO2 solution is evenly sprayed on the surface of the light-storage ceramic by spraying with a sprayer, which has high equipment cost, high technical requirements for personnel, and a thin spraying thickness, which is easy to cause the self-cleaning ability to decrease after long-term use.

[0005] In another patent document CN103643773B, the application date is December 12, 2013, which discloses a photoluminescent ceramic tile and its production method. Photoluminescent materials are printed or clothed on ceramic bisque blanks to form a photoluminescent glass layer, which can present multiple colors in the dark and has a long afterglow time. The process can adopt screen printing or cloth process, and the pattern can be changed at any time. With the color material toning and concave and convex molds, a variety of decorative art effects with strong three-dimensional sense and rich pattern layers can be presented. The method disclosed in the present invention solves the problems of poor wear resistance, weather resistance and chemical corrosion resistance of existing photoluminescent materials. Photoluminescent materials are printed or clothed on ceramic bisque blanks to form a photoluminescent glass layer. However, considering that the photoluminescent glass layer is made by printing or cloth process, the thickness of the glaze layer is limited, the storage material is limited, and the light storage effect is limited. As the glaze layer wears over time, the light storage effect will also decrease. The existing technology seems to be slightly insufficient.

[0006] Patent document CN202311779853.5 discloses a pressure forming preparation method for light-storage ceramics, comprising: S1: preparing an alkaline solution with a concentration of 1 to 45 wt%; S2: mixing the alkaline solution and low-melting-point glass powder, and stirring to obtain a mixture; S3: heating the mixture to keep it moist and form a water glass film on the surface of the low-melting-point glass powder; S4: drying the product of step S3 to evaporate excess water so that the material is in block form;

[0007] S5: material crushing, screening and granulation to obtain particles with certain fluidity; S6: the particles of step S5 are mixed with light-storage materials evenly and dry pressed; S7: the dry pressed green blank is sent to a kiln for sintering, and the light-storage ceramic product is obtained after it is taken out of the kiln. The present invention forms a water glass film with uniform thickness on the surface of glass particles through the reaction between the alkaline solution and silicon dioxide by adding an alkaline solution, solves the problem of difficulty in uniformly adding water glass binder during the powder mixing process, makes the pressure forming process applicable to the production of light-storage ceramics, obtains the green blank by dry pressing, and sintering the dry pressed green blank to obtain the light-storage ceramic product. However, considering that the prior art needs to crush the material, then screen and granulate, and mix and dry press, the preparation cycle is long, which increases the difficulty and complexity of the process, and it is easy to mix impurities, resulting in reduced quality of the finished product. The required molding equipment is costly and technically difficult, and the prior art appears to be slightly insufficient. Summary of the invention
