Embodiment Construction

[0024]In terms of parts by weight, weigh 45 to 50 parts of 98% sulfuric acid by mass fraction, 3 to 5 parts of 200 mesh expanded graphite powder and 6 to 8 parts of potassium permanganate in a beaker, stir and mix them and place them at 0 to 5 ℃ for 20-30 minutes in a water bath to obtain the reaction solution and raise the temperature to 35-40 ℃. After the heat preservation reaction for 1-2 hours, the heated reaction solution was collected and counted in parts by weight. Weighed 45-50 parts of deionized water, 15 ~20 parts of 10% hydrogen peroxide solution by mass fraction and 15~20 parts of heating reaction solution are placed in an Erlenmeyer flask, stirred and mixed, and placed at 45~50°C for 25~30min, and after standing for 20~24h, filter and Collect the lower precipitate, wash the lower precipitate with water until the washing solution is neutral, and then dry at 55-65°C for 6-8 hours to obtain dry graphite oxide particles; weigh 45-50 parts by weight Deionized water, 15...

Abstract

The invention relates to a preparation method of a formaldehyde decomposition type heating radiator coating material with a high absorption rate and belongs to the technical field of coatings. According to the technical scheme, 18-crown ether-6 is taken as a template agent, a hexagonal crystal EMT molecular sieve is successfully prepared with a steam crystallization technology and supported on thesurface of an aerogel material packet, a potassium chloride solution is supported, and potassium elements are more uniformly distributed in the molecular sieve. Meanwhile, cations in the prepared molecular sieve are in different positions, have different steric hindrance and have different energy, so that the cations are stable in molecular sieve channels, and the functions of regulating the surface characteristics and the pore structures of the molecular sieve are realized; the molecular sieve has a large specific surface area and pore volume, more adsorption sites can be provided, and the oxygen adsorption of the molecular sieve is increased; besides, the composite aerogel material has excellent specific surface area and structure performance, the bonding strength and the adsorption performance of the material are further improved, and the composite material has excellent adsorption performance.

Description

technical field [0001] The invention relates to a preparation method of a formaldehyde-decomposing radiator coating material with high absorption rate, and belongs to the technical field of coatings. Background technique [0002] Formaldehyde is a common pollutant in the indoor atmosphere, and it has high toxicity. Short-term exposure to low concentrations of formaldehyde can irritate the eyes and respiratory tract and cause allergic reactions, and long-term exposure to trace amounts of formaldehyde can increase the possibility of cancer. Formaldehyde has been identified as a teratogenic and carcinogenic substance by the World Health Organization. The "Indoor Air Quality Standard" (GB / T18883-2002), which was implemented in my country in 2003, stipulates that the maximum allowable concentration of formaldehyde in indoor air is 0.10 mg per cubic meter (1 hour average). In summer in the north, windows can be opened to use air convection to discharge formaldehyde, but in winte...
