Normal-temperature air suction composite material and product thereof

The invention belongs to the technical field of air suction materials, and particularly relates to a normal-temperature air suction composite material and a product thereof. The normal-temperature airsuction composite material is a multi-component mixture and comprises an alkaline-earth metal oxide, a rare-earth metal oxide, a transition metal and a transition metal oxide, is high in water absorption rate, complete in air suction, lower in gas balance pressure, can maintain a good vacuum environment effectively; the transition metal is added, so that the air suction capability is improved, inaddition, the catalyst effect is improved greatly through synthetic effect with a metal oxide, so that the whole performance of the normal-temperature air suction composite material is assisted to beimproved; the normal-temperature air suction composite material contains no toxic and harmful substances, is friendly to human bodies and the environment, and is low in application condition requirement, and has great populari
