Embodiment Construction
[0156] Implementation Case (1).
[0157] The preparation of a rare earth modified zeolite molecular sieve comprises the following steps.
[0158] ① Material component A: natural zeolite powder, dilute sulfuric acid solution, distilled water, sodium hydroxide solution, sodium metaaluminate, deionized water, ammonia water, La solution.
[0159] ②Preparation of zeolite molecular sieve:
[0160] Weigh a certain amount of natural zeolite powder, put it into 1mol / L dilute sulfuric acid solution, soak for 2 hours, filter, wash with distilled water until neutral, dry, then put in 30% NaOH solution, stir at 90°C for 4 hours, To obtain a gel mixture, add sodium metaaluminate and deionized water into the gel mixture in a certain proportion (sodium metaaluminate and sodium hydroxide in a mass ratio of 10:1), and keep stirring, crystallize for 6 hours, filter, Wash until neutral and dry to obtain zeolite molecular sieve.

Abstract
The invention relates to a nano rare earth zeolite coating. A nano material and functional groups are grafted by activating a microporous material and dispersing modified adsorbed nanoparticles; by means of physical action such as photocatalytic action and dipole moment, harmful substances, for example, TDI released by carbon monoxide, hydroxide, formaldehyde, benzene and polyurethane, in air aredecomposed and absorbed, so that the coating has the novel functions of removing smoke smell, odor, being mildewproof and antibacterial, killing bacteria and viruses, regulating temperature and humidity and purifying indoor air. Moreover, the coating releases negative ions and far infrared rays and diffuses plant fragrance permanently, and the color of the pattern is selected randomly. The coatingis bagged, so that the cost is saved. The materials are easily selected, and the coating is low in production cost, pollution-free, high in cost performance and high in scientific content. During construction, no glue is used, and the coating is directly sprayed, brushed, roll-sprayed and scrape-sprayed. The coating is good in adhesion, smooth in hand feeling, bright and flexible in feeling and comfortable and attractive. The coating is widely applied to the field of coating of buildings, and is suitable for the occasions such as habitable rooms, office rooms, hospitals, hotels and restaurants.
Description
technical field [0001] The invention relates to a construction field: specifically, nano-rare-earth zeolite coatings, including nano-rare-earth zeolite interior wall coatings and nano-rare-earth zeolite exterior wall coatings. Background technique [0002] Nanotechnology is a preface and interdisciplinary new discipline gradually developed in the 1980s. Since the advent of nanotechnology, its unique ideas have aroused great repercussions in the scientific and technological circles, and have attracted widespread attention from all walks of life. The United States Amotrongs, chief scientist of IBM, said: "Just as microelectronics technology triggered the information revolution in the 1970s, nanotechnology will also become the core of the information age in the next century." The rapid development of nanotechnology plays an important role in the development of science and technology in the 21st century. It is another hot spot after the Internet and genes. In today's society, w...
