Embodiment Construction

[0017] The production method of the light-weight thermal insulation wall panel for purifying air of the present embodiment has the following specific steps to prepare:

[0018] (1) Pulverize kaolin; add the pulverized kaolin to 10 times the weight of potassium acetate solution, stir magnetically at room temperature for 4 days, filter, wash, and centrifuge, and dry the centrifuged product in an electric blast drying oven for 24 hours ; Transfer the dried product to a muffle furnace and heat it up to 800°C for 4 hours, then cool it under natural conditions, ball mill it for 20 minutes, and pass through a 150-mesh sieve to obtain high-temperature expanded kaolin;

[0019] (2) Add n-butyl titanate to absolute ethanol, stir at room temperature for 4 hours, add high-temperature expanded kaolin, ultrasonically oscillate for 6 hours, filter, wash the filter cake with absolute ethanol and water for 3 times, and place in a vacuum oven at 65°C Dry for 20 hours, put the dried product into...

Abstract

The invention discloses a method for producing light heat-insulation wall panels with air purification functions. The method is characterized by comprising steps of expanding kaolin at the high temperatures; hydrolyzing tetrabutyl titanate and carrying out intercalation modification on the kaolin expanded at the high temperatures; preparing foaming slurry from fly ash, cement, porous ceramsite andthe modified kaolin by the aid of mechanical foaming processes; carrying out form filling, vibration, static maintenance, steam-pressure maintenance and drying to obtain the light heat-insulation wall panels with the air purification functions. The fly ash, the cement and the porous ceramsite are used as main raw materials and are assisted by the modified kaolin. The method has the advantages that air refreshing, antibacterial and anti-mildew effects can be realized by the light heat-insulation wall panels with the air purification functions, the light heat-insulation wall panels are light and are low in cost, high in strength and convenient to construct and mount, and outstanding heat preservation, heat-insulation and sound-insulation effects can be realized by the light heat-insulationwall panels.

Description

technical field [0001] The invention relates to the construction field, in particular to a production method of a light-weight thermal insulation wall panel for purifying air. Background technique [0002] Foamed concrete, also known as foamed cement, lightweight concrete, etc., is a new type of building energy-saving material that is waste-friendly, environmentally friendly, energy-saving, inexpensive and non-combustible. Foamed concrete is to introduce air or nitrogen, carbon dioxide, oxygen and other gases into the concrete slurry according to the application needs through chemical or physical means, and after reasonable maintenance and molding, it forms a concrete with a large number of small closed pores and has considerable strength. products. At present, foam concrete is used as building wall material, which has a good energy-saving effect, but it has defects such as low strength, cracking, and water absorption in application, and its performance needs to be further ...
