Abstract

The invention provides a ceramic composite with high absorptive property. The ceramic composite is composed of the following components in percentage by weight: 9.3 to 74.5 percent of bamboo charcoal powder, 0.2 to 0.5 percent of graphene, 0.5 to 5 percent of tianium dioxide, 10 to 80 percent of tourmaline crystal particles and 10 to 80 percent of clay. The ceramic composite with high absorptive property has the advantages of large specific surface area and light self-cleaning capability, and is capable of effectively absorbing harmful gases such as formaldehyde and benzene, thereby purifying air; the preparation method is simple and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of composite ceramic materials, in particular to a ceramic composition with high adsorption performance and a preparation method thereof. Background technique [0002] Tourmaline is a silicate mineral with a ring structure of aluminum, iron, sodium, magnesium, and lithium, which is characterized by boron. It is black or gray-black, and has a thick needle, bundle, or radial structure. Tourmaline has special pyroelectricity and piezoelectricity, has high far-infrared radiation and negative ion release ability, and contains a variety of trace elements beneficial to human health. It is widely used in drinking water activation, air purification, sewage treatment, Ceramics, building materials, daily chemicals, electronics, textiles, health care products, beauty cosmetics and other fields. [0003] Bamboo charcoal has a rich honeycomb microporous structure. This microporous structure makes bamboo charcoal have a l...
