Problems solved by technology

At present, the common similar products on the market are derivatives of latex paint, wallpaper and diatomaceous earth. They are only formaldehyde-free for their own environmental protection, or have a weak formaldehyde-absorbing function, and cannot remove formaldehyde and other harmful volatiles released by other furniture materials. Carry out adsorption and decomposition, the effect is greatly limited

Embodiment 1

[0024] Preparation of Modified Metal Organic Framework Compounds

[0025] Specifically take the following steps:

[0026] (1) Add zinc nitrate hexahydrate and 2-methylimidazole with a molar ratio of 1:(1.5-6) ​​to the reactor, and then add 3,4-diamino with a molar ratio of 1:(20-40) A mixed solution of benzenesulfonic acid and N'N-dimethylformamide, the molar amount of N'N-dimethylformamide is 25-60 times the total molar amount of solid reactants, then stirred at room temperature for 5-20 minutes, and then 110 -120℃ constant temperature reaction for 20-24h;

[0027] (2) Step (1) After the constant temperature reaction is completed, naturally cool to room temperature, take out and ultrasonically treat for 15-20 minutes, then suction filter and wash with absolute ethanol three times, and filter the product after drying and mix with titanium dioxide sol with a concentration of 0.75mol / L The modified metal organic framework compound can be obtained by mixing and grinding in a ba...

Abstract

The invention discloses a nano metal organic frame wall material with environmental protection purification function and a preparation method thereof. The material itself is environmentally friendly, pollution-free, and has no toxic effect on human body; it contains modified metal organic frame compound, zeolite and diatomite, which can It can effectively absorb toxic and harmful substances in the air and purify the air; it contains nano-zinc oxide and nano-silver, which can decompose the formaldehyde gas adsorbed by modified metal organic framework compounds, zeolite and diatomite into water and carbon dioxide under natural light, which can It can effectively solve the problem of formaldehyde adsorption and saturation of wall materials; in addition, it contains nano tourmaline powder, which is a natural mineral material and has the function of releasing negative oxygen ions, which can increase the content of negative oxygen ions in the indoor environment, improve indoor air, and improve the comfort of the home environment. In addition, the nano metal organic frame wall material also has fire-retardant and flame-retardant effects, and can withstand high temperature burning at 350 degrees; the important thing is that the preparation method is simple and has high practicability.

Description

technical field [0001] The invention relates to the technical field of material chemistry, and more specifically relates to a wall material containing nanometer metal organic framework with environmental protection and purification functions and a preparation method thereof. Background technique [0002] With the development of the economy, various chemical and chemical industries have also developed vigorously, people's living standards have also been greatly improved, and various beautiful interior decoration materials and furniture have been widely used. However, a large number of chemical and chemical decoration and building materials have entered the family, resulting in serious indoor air pollution in most families, and volatile toxic and harmful gases such as formaldehyde, benzene, and toluene have seriously exceeded the standard. Formaldehyde, benzene, ammonia, etc. are extremely harmful to human health, and are listed as strong carcinogens by the World Health Organi...
