Abstract

The invention discloses a high-adsorbability environment-friendly hollow glass drying agent. The high-adsorbability environment-friendly hollow glass drying agent is prepared from 80% to 90% of attapulgite powder, 2% to 6% of magnesium perchlorate, 0.2% to 0.3% of quaternary alkyl-ammonium-based surface active agent, 2% to 6% of sodium aluminate and 4% to 8% of cationic polyacrylamide. The invention discloses a preparation method of the high-adsorbability environment-friendly hollow glass drying agent at the same time. The drying agent is a hollow glass drying agent with high adsorbability and an environmental protection property, the adsorption performance is efficient and long, and the environmental protection property is good.

Description

technical field [0001] The invention relates to the field of desiccant materials, in particular to a hollow glass desiccant with high adsorption and environmental protection. Background technique [0002] A desiccant is a material with a high affinity with moisture, which can absorb moisture from other surrounding materials through adsorption to achieve the purpose of drying. The adsorption phenomenon is a phenomenon in which water phase molecules or gas phase molecules gather on the surface of a solid and are combined through intermolecular interactions. Because adsorption is a molecular surface phenomenon, in order to achieve the purpose of adsorption, the solid adsorbent must have a large of the inner surface area. The solid desiccant used in hollow glass is a kind of solid adsorbent, which removes the moisture in the air layer through the physical method of adsorption. [0003] The purpose of using desiccant in the air layer of insulating glass is mainly to absorb the ...
