Abstract

The invention provides a load type honeycomb ceramic catalytic material which is prepared from, by weight parts, 100-200 parts of honeycomb ceramics, 0.6-1.4 parts of manganese salt, 0.1-12 parts of ferric salt, copper salt, cerium salt or zinc salt, 4-18 parts of catalyst carrier, 0.5-14 parts of nanoscale anion powder, 0.45-3 parts of inorganic binder, 0.05-1.2 parts of organic binder, 0.2-1 part of surfactant and 60-90 parts of water. The load type honeycomb ceramic catalytic material is low in cost and can efficiently remove formaldehyde and purify air under conditions of indoor temperature, high humidity and large blast capacity. The invention further provides a method for preparing the load type honeycomb ceramic catalytic material. The method is simple, convenient to use, low in production cost and favorable for achieving industrial production and large-scale popularization.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of environmental protection, in particular to a supported honeycomb ceramic catalytic material and a preparation method thereof. [0003] 【Background technique】 [0004] The problem of indoor air formaldehyde pollution caused by decoration or decoration materials is very serious and has attracted great attention worldwide. Studies have shown that formaldehyde is a highly toxic substance. Short-term exposure to formaldehyde can irritate the eyes, nasal cavity and respiratory tract and cause allergic reactions; long-term exposure to low-dose formaldehyde can increase the possibility of nasopharyngeal cancer, leukemia and death. In the "Indoor Air Quality Standard" (GB / T18883~2002) promulgated by China in 2002, the hygienic standard (maximum allowable concentration) of formaldehyde in indoor air is 0.10mg / m 3 . Therefore, it is imminent to remove formaldehyde in indoor air. [0005] Adsorption method, plasma t...
