Embodiment 1

[0011] Example 1: 40.1% Al by weight 2 o 3 , 43.3% SiO 2 , 15.0% MgO, 1.6% ZnO, mixed various components, wet ball milled for 16 hours, the ratio of material: ball: water was 1:2:1.5, the slurry was dried at 80-100°C, and then put Put it into a crucible for solid phase synthesis at 1400°C for 4 hours, and the solid phase synthesis product is ground and passed through a 250 mesh sieve to make white ceramic powder.

[0012] The normal full-band emissivity of the ceramic powder is 0.89, the emissivity of the 8-25 μm band is 0.92, the emissivity of the 8-14 μm band is 0.90, and the emissivity of the 14-25 μm band is 0.94. The antibacterial rate of ceramic powder to urea Sarcina was 100%, and the antibacterial rate to Staphylococcus aureus was 86.7%.

[0013] raw material

[0014] The above percentages are percentages by weight. The corresponding infrared radiation ceramic powder can be obtained by referring to the method of Example 1 according to the above proportion...

Abstract

The present invention relates to one kind of solid solution cordierite series ceramic powder with infrared radiation and bacteriostasis functions and its preparation process. The ceramic powder has the main components of Al2O3, SiO2, MgO and ZnO, which are prepared into white solid solution cordierite series ceramic powder through ceramic making process. The ceramic powder has normal whole waveband radiance of 0.87-0.90, 8-25 micron waveband radiance of 0.90-0.94, 8-14 micron waveband radiance of 0.88-0.94 and 14-25 micron waveband radiance of 0.91-0.94. The bacteriostasis function test shows that the ceramic powder has obvious inhibiting effect on urea sarcin and Staphylococcus aureus, with bacteriostasis rate reaching 84.1-100 %. The present invention has simple process, low cost and wide application range.

Description

technical field [0001] The invention relates to a solid-solution cordierite system ceramic powder with infrared radiation function and antibacterial function and a preparation method thereof, belonging to the field of infrared radiation materials. Background technique [0002] Infrared radiation ceramic powder is a kind of ceramic material that uses oxide as raw material and is prepared by ceramic processing technology. It has a high emissivity in the infrared band. Infrared radiation can be absorbed by objects, and thermal effects are an important feature of infrared radiation. When infrared radiation acts on the human body, it can be absorbed by the skin and converted into heat energy, which can dilate blood vessels, improve blood flow, increase the activity of cells and biological enzymes, mobilize and enhance the body's own immunity, so that infrared radiation can play a role in medical care. . In addition, because infrared radiation has a ce...
