Abstract

The invention relates to diatomite composite material which can generate negative oxygen ions and a preparation method thereof. Element constitution and weight proportion of the composite material are Ti(OH)4: (4-33) of the diatomite: 100. The preparation method includes the following steps and conditions: the Ti(OH)4 is weighed by the weight proportion and is put into water for pulp beating; the Ti(OH)4 is scattered into emulsion; the diatomite by the weight proportion is added and stirred; ultrasonic dispersion of the mixture is carried out for 30 minutes; then the mixture is evaporated to dry; the mixture is taken out to be incandesced for 2-5 hours under 500-800 DEG C. Through a test by using an ITC 201A anion detector made in Japan, the number of the negative oxygen ions provided by the diatomite composite material which can generate the negative oxygen ions is more than 500 per cm<3>. The negative oxygen ions in air are vitamin of the air and have the functions of dust suppression, sterilization, purification and physiological health care, etc. When concentration of the negative oxygen ions in the air achieves a certain degree, the negative oxygen ions are in favor of human body and have the function of disease treatment.

Description

technical field [0001] The invention relates to a diatomite composite material capable of generating negative oxygen ions and a preparation method. Background technique [0002] Diatomaceous earth is a natural mineral deposited by paleontological diatoms. It has a special porous structure (pore size of about 20nm to several μm) and physical properties, such as large porosity and strong adsorption. It has become a rare natural resource. my country's diatomite resources are relatively rich, and its total reserves occupy the second place in the world. Jilin Province's diatomite accounts for 51% of the national reserves, and its grade is relatively high. [0003] The development and utilization of diatomite started in the 1960s in my country. At present, there are eight series of diatomite products and dozens of products, such as cement mixture materials, thermal insulation materials, filter aids, fillers and catalyst carriers. Using diatomite's porous structure, large specifi...
