The invention discloses an attapulgite argil powder with an air purifying function. The technical scheme is as follows: the attapulgite argil powder with an air purifying function is prepared from high-viscosity attapulgite clay, an attapulgite constant-humidity conditioner, a natural mineral adsorbing/filtering agent, Cacumen Biotae, aluminum silicate fiber and polyacrylamide. The attapulgite argil powder is prepared by the following steps: pulverizing the materials, soaking and aging to obtain a wet mixture, extruding the wet mixture into a strip, airing the strip, pulverizing to obtain powder, and packaging to obtain the finished product. The attapulgite argil powder has favorable cohesive property, plasticity, thixotropy, fire resistance and thermal stability; the pottery prepared from the attapulgite argil powder with an air purifying function contains a great deal of micropores and activated carbon, thus, has the characteristics of low shrinkage, no cracking or deformation and favorable adsorbability, and can effectively adsorb formaldehyde, ammonia, benzene and other harmful substances in the air, thereby protecting the environment and improving good health of people. The invention is suitable for producing pottery artware with an air purifying function.
