Description

Technical Field

[0001] The present invention relates to the field of building technology, and particularly relates to a nano-functional material with high release of negative oxygen ions and a strengthening method thereof. Background Art

[0002] The Qinghai-Tibet Plateau is located in the interior of Asia and is the highest plateau in the world. It is known as the "Roof of the World" and the "Third Pole", with unique natural landscapes. Tourism has become an important pillar industry for promoting the economic development of the Qinghai-Tibet Plateau region and improving the happiness of local residents. With the increasing activities such as tourism, aid to Tibet construction, and scientific expeditions on the Qinghai-Tibet Plateau, more than 90 million people from low-altitude areas enter the Qinghai-Tibet Plateau every year. However, the average altitude of the Qinghai-Tibet Plateau exceeds 4000m, and the altitude sickness caused by low pressure and low oxygen in high-altitude areas will bring discomfort to people who first enter the plateau and even endanger their lives. How to ensure the physical and mental health of foreign populations under hypoxic stress conditions is a huge challenge. Therefore, developing new materials that are beneficial to physical health and can be widely applied to improve the hypoxic environment on the plateau is of great significance for promoting the development of the Qinghai-Tibet Plateau, carrying out the construction and optimization of the human settlement environment, and promoting the economic development of the Qinghai-Tibet Plateau.

[0003] With the rapid development of social economy and modern industry, urban environmental problems have become increasingly prominent. The severe air pollution situation has caused serious impacts on people's physical health. The degree of indoor air pollution is 4-8 times that of the outdoor environment. In particular, volatile organic pollutants in newly decorated houses pose a fatal threat to the physical health of residents. More and more people begin to pay attention to indoor air quality, which is an important standard for indicating the livability index of the space environment and the degree of impact on human health. At present, many countries in the world have regarded the release level of negative oxygen ions as an important indicator for measuring air cleanliness and evaluating air quality. Negative oxygen ions are beneficial to human health and can purify the air and improve the environment, degrading and neutralizing harmful gases in the air. Therefore, researching and developing a nano-functional material with high release of negative oxygen ions and a strengthening method thereof has important value for improving the health level of residents.

The negative oxygen ion high-releasing nano-scale functional material comprises 5-15%, 5-15%, 15-20%, 5-15%, 15-20%, 5-15% and 15-20% of sepiolite, zeolite, tourmaline, barite, hexacyclic stone, cassia stone and epoxy resin E51.

[0017] A method for strengthening a negative oxygen ion high-release nano-scale functional material, the technical solution of which is achieved by the following steps: Step 1: fully mix sepiolite, zeolite, tourmaline, barite, hexacyclic stone, guibaoshi and epoxy resin E51 according to the mass percentage of 5-15%, 5-15%, 15-20%, 5-15%, 15-20%, 5-15% and 15-20%, the particle size is 2-5mm, and extrude at a high temperature of 120°C through a powder equipment, and then cool and tablet, the pressure is 10-15 MPa, and grind into nano-grade negative ion powder by machine for standby use; Step 2: diluting the negative ion liquid with the function of releasing negative ions in situ obtained from tourmaline and hexachlorobenzene by leaching and extraction methods with water to obtain a diluted negative ion liquid, wherein the dilution ratio is 5%-100%, and the negative ion liquid is reserved; the leaching and extraction method is: grinding tourmaline and hexachlorobenzene into ultrafine powders according to a mass ratio of 1:1, mixing the powder with water according to a ratio of 5:1, and soaking for 30 minutes to obtain the negative ion liquid; Step 3: For the existing concrete pouring wall surface, first brush the high permeability wall curing base (for example, high permeability Jiale coating wall solidifier can be used) and then scrape and apply plaster for leveling. This step is the existing technology and will not be repeated here; Step 4: Mix the nanometer-scale negative ion powder obtained in step 1 with water in a mass ratio of 1:0.6, and then evenly apply it on the basis of step 3 to a thickness of 2-3 mm.

[0018] In order to further increase the amount of negative ion release, step five is carried out on the basis of step four: the diluted negative ion liquid obtained in step two is sprayed evenly on the wall once, with a dosage of 10mL / m 2 Here, it should be noted that the negative ion liquid or diluted negative ion liquid sprayed directly on the concrete wall cannot play the role of enhancing the release of negative ions. Therefore, this step of the present invention adopts spraying the negative ion liquid on the basis of step four.
