Embodiment 1

[0023] A method for preparing a formaldehyde catalytic material at room temperature, specifically as follows: Potassium permanganate, manganese sulfate, and sodium hydroxide are respectively configured at a mass ratio of 1:1.2:0.3 so that the concentrations are 15g / L, 46g / L, and 20g / L. After potassium permanganate and sodium hydroxide solution are mixed and reacted, under stirring conditions, the prepared divalent manganese ion aqueous solution and strong alkali aqueous solution are poured into the permanganate aqueous solution, and stirred for 2 hours. After the reaction is completed, stand still for 30 minutes, press filter, wash, dry and crush to obtain the formaldehyde-removing functional powder of the normal-temperature formaldehyde catalytic material. Then mix it with 13X molecular sieve, attapulgite clay, glycerin, and water in a mass ratio of 1:0.5:2.5:0.25:1.85, and then extrude it through an extruder to form it. First, it is dried in an oven at 110°C, and then After ...

Embodiment 2

[0025] A preparation method of formaldehyde catalytic material at normal temperature, specifically as follows: sodium permanganate, manganese acetate, and sodium hydroxide are respectively configured into 17g / L, 75g / L, and 20g / L solutions at a mass ratio of 1:2.4:0.5, and After potassium permanganate and sodium hydroxide solution are mixed and reacted, under stirring condition, the prepared divalent manganese ion aqueous solution and strong alkali aqueous solution are poured into the permanganate aqueous solution and stirred for 4 hours. After the reaction is completed, stand still for 60 minutes, press filter, wash, dry and crush to obtain the formaldehyde-removing functional powder of the normal-temperature formaldehyde catalytic material. Then mix it with 10X type, structural adhesion aid (attapulgite clay and modified bentonite (mass ratio: 1:0.5) gradation preparation), scallop powder, and water in a mass ratio of 1:2.5:2.3:0.15: 2.45 After mixing evenly, it is extruded t...

Abstract

The invention discloses a room temperature formaldehyde catalytic material and a preparation method thereof. The preparation method includes: subjecting formaldehyde removal functional powder, a molecular sieve, a structural bonding assistant, a structural lubricating assistant and deionized water to material mixing, kneading, extrusion forming, drying and roasting, thus obtaining the cylindrical particle room temperature formaldehyde catalytic material. The room temperature formaldehyde catalytic material provided by the invention converts indoor air pollutant formaldehyde into harmless water and carbon dioxide under the catalytic oxidation effect of a purification material, and does not produce secondary pollution. Under room temperature conditions, the formaldehyde catalytic material has a good purification effect on high concentration and low concentration formaldehyde, and a 1h formaldehyde purifying rate can reach more than 98%. In addition, the room temperature formaldehyde catalytic material also has good efficacy of purifying ammonia and hydrogen sulfide and removing peculiar smell, is convenient to use, and the preparation process is simple and is easy to operate, and the needed raw materials have stable properties and are environment-friendly, and do not cause environmental pollution.

Description

technical field [0001] The invention relates to a catalytic material and a preparation method thereof, in particular to a normal temperature formaldehyde catalytic material and a preparation method thereof. Background technique [0002] Formaldehyde pollution mainly comes from wood-based panels and paints in decoration or furniture, which is deep pollution. Formaldehyde, which is known as the "invisible killer" in daily life, has a release cycle of up to 15 years, and it is difficult to completely remove it by general removal methods. Formaldehyde is a gaseous pollutant that is highly irritating to the eyes and mucous membranes of the respiratory tract. Long-term inhalation can cause cancer, respiratory diseases, reduce human immunity and various diseases. A large amount of formaldehyde and urea-formaldehyde resin glue are added in the production of wood-based panels, and a large number of wood-based panels are used in decoration, which has caused a source of decoration pol...
