Abstract

The invention discloses a hollow glass drying agent and a preparation method thereof. The drying agent is prepared from the following raw materials: diatomite, straw powder, foam aluminum, magnesium perchlorate, polyacrylamide, aluminum sulfate, sodium hexametaphosphate, titanium dioxide, polyethylene, a surfactant and de-ionized water. The preparation method comprises the following steps: mixing and combusting the straw powder and the diatomite to obtain mixture ash; mixing and grinding the foam aluminum, the polyacrylamide, the titanium dioxide, the polyethylene and the de-ionized water to obtain a first mixture; adding the magnesium perchlorate, the aluminum sulfate, the sodium hexametaphosphate and the surfactant into a reaction kettle; heating to 120 DEG C to 180 DEG C and adding a first mixture; stirring and raising the temperature to 340 DEG C to 450 DEG C; adding the mixture into a double-screw extruder and extruding to obtain grains. The drying agent disclosed by the invention has the advantages of low cost, large specific surface area and large static water absorption amount, is not easily influenced by temperature and humidity and has a stable absorption capability. A preparation process is simple, and the components are more tightly fused and are not easy to disintegrate.

Description

technical field [0001] The invention relates to the field of desiccants, in particular to a hollow glass desiccant and a preparation method thereof. Background technique [0002] With the improvement of living standards, insulating glass stands out in the building materials market because of its advantages of energy saving and environmental protection, and has become a product that is prioritized by various countries. At present, most insulating glass adopts double seals. The first seal uses butyl rubber to prevent water vapor from entering; the second seal uses polysulfide glue, polyurethane glue, silicone glue, etc. to maintain structural stability. However, tiny water molecules can still enter the insulating glass through the sealing system, coupled with the air moisture sealed inside the insulating glass during production, the performance and service life of the insulating glass are still at risk. [0003] Desiccant combined with sealing technology maintains the stabi...
