Flake plastic silicon oxide drying agent and preparation method thereof

Abstract

The invention relates to a flake plastic silicon oxide drying agent and a preparation method thereof. The flake plastic silicon oxide drying agent comprises the following components in percentage by weight: 50-90 percent of silicon oxide, 10-50 percent of high-molecule plastic and 0-5 percent of auxiliary material. Compared with the prior art, the flake plastic silicon oxide drying agent can be more consistent with a space for placing the drying agent, can be directly used without packing, and is safe and environmental friendly; moreover, the amount of drying agent placed in the space is greatly increased, and the moisture absorption capacity is higher under the same volume; the method can realize automatic production and has great application prospect and economic value.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a plastic silicon dioxide flake desiccant and a preparation method thereof. Background technique [0002] With the widespread use of desiccants, it is required that the desiccant be smaller in size and better fit the packaging container; it is also required that the desiccant is safe and reliable during use, has stable hygroscopic performance, and can be regenerated and used repeatedly. [0003] In recent years, bagged silica gel and other desiccants have been widely used. The main defect is that silica gel and other desiccants must be repacked with air-permeable non-woven fabrics or paper, and cannot be directly attached to the product packaging that requires desiccant. , and the bagged silica gel desiccant will fall and break, which may cause secondary pollution of the product; and the traditional bagged silica gel desiccant placement process can only be placed manually, and c...

Problems solved by technology

[0003] In recent years, bagged silica gel and other desiccants have been widely used. The main defect is that silica gel and other desiccants must be repacked with air-permeable non-woven fabrics or paper, and cannot be directly attached to the product packaging that requires desiccant. , and the bagged silica gel desiccant will fall and break, which may cause secondary pollution of the product; and the traditional bagged silica gel desiccant placement process can only be placed manually, and continuous automatic delivery cannot be realized, thus limiting its automation. industry process

[0005] The disadvantages of the above technical content are: the desiccant must be repacked with breathable non-woven fabric or paper before it can be used in various moisture-proof fields; and the amount of space is small, and the total absorption is bound to be low
