[0059] The present invention also provides a method for preparing the porous catalytic honeycomb ceramic material as described in any one of the above technical solutions, comprising the following steps:

[0060] Weigh nano low-temperature frit glaze, attapulgite, modified diatomite and modified tourmaline powder in parts by weight, add appropriate amount of lubricant and water, mix by ball milling for 3-10 hours, extrude and form at 100-120°C After drying for 2-10 hours under high temperature, it is sintered at 750-850° C. to obtain a porous catalytic honeycomb ceramic material.

[0061] In this step, after preparing the raw materials, add an appropriate amount of lubricant and water to the raw materials, use a ball mill with the ball as stone for ball milling and mixing, use a general extrusion molding method for molding, and perform low-temperature sintering after drying, which can effectively meet the requirements of diatomite. Amorphization, not greatly sacrificing the am...

Embodiment 1

[0069] Weigh 27 parts of nano low-temperature frit glaze, 40 parts of attapulgite, 25 parts of modified diatomite and 5 parts of modified tourmaline powder by weight, add an appropriate amount of lubricant, and use a ball mill with a ball as a stone to mill the above raw materials After mixing for 3 hours, extrusion molding, drying at 100° C. for 8 hours, calcining at 750° C., and keeping at this temperature for 1 hour to obtain a porous catalytic honeycomb ceramic material.

[0070] The calcined porous pottery particles are immersed in 3 parts by weight of tetrabutyl titanate, taken out after saturation, dried and then calcined and decomposed at 400°C. The pores or surfaces of the pottery particles are covered with a nano-titanium oxide layer to obtain multifunctional porous ceramic particles. Catalytic honeycomb ceramic material with a pore size of about 0.5-10mm.

Embodiment 2

[0076]Weigh 25 parts of nano low-temperature frit glaze, 25 parts of attapulgite, 30 parts of modified diatomite and 20 parts of modified tourmaline powder by weight, add an appropriate amount of lubricant, and use a ball mill with a ball as a stone to mill the above raw materials After mixing for 5 hours, extrusion molding, drying at 110° C. for 5 hours, calcining at 800° C., and maintaining at this temperature for 2 hours, a porous catalytic honeycomb ceramic material was obtained.

[0077] Immerse the calcined porous pottery plate into 2 parts by weight of a true solution of saturated concentration prepared by ammonium metatungstate and praseodymium nitrate composite material, take it out after saturation, dry it, and then calcine and decompose it at 500°C. The pores or the surface are covered with a nano-tungsten oxide / nano-praseodymium oxide layer to obtain a multifunctional porous catalytic ceramic plate with a pore diameter of about 300nm and a size of 20×20×2.5cm.

Description

technical field [0001] The invention belongs to the technical field of catalytic materials, and in particular relates to a porous catalytic honeycomb pottery material, a multifunctional porous catalytic honeycomb pottery material and a preparation method thereof. Background technique [0002] At present, a large number of civil buildings in China mostly rely on natural ventilation to achieve indoor ventilation. However, in recent years, due to factors such as motor vehicle exhaust emissions, industrial exhaust emissions, and engineering construction, the air quality outside urban buildings has caused high concentrations of pollution, especially in hazy days. The role of natural ventilation is no longer to dilute indoor air pollution, but to worsen indoor air quality. [0003] At present, indoor adsorbents are usually used to improve indoor air quality, including but not limited to activated carbon, bamboo charcoal and coconut shell charcoal. It takes a long time and cannot...
