Water-absorbent resin for hermetic damp-proof medicine bottle

Abstract

The invention discloses water-absorbent resin for a hermetic damp-proof medicine bottle. A preparation method of a water-absorbent high polymer material includes: step 1, peeling, drying, crushing andgrinding sweet potatoes to obtain sweet potato powder, washing with alkaline liquid for 120-150min at 100-120 DEG C and under the normal pressure, filtering and drying, wherein the washing time is adjustable according to different sweet potato surface properties; step 2, adopting an activating agent for surface activation of the sweet potato powder obtained in the step 1, well mixing the activating agent with the sweet potato powder, and performing reaction for 6-8h at 50-100 DEG C and under the normal pressure to obtain activated modified sweet potato powder; step 3, well mixing the sweet potato powder obtained in the step 1, ethyl acrylic acid, 100-200 parts of water and 0.1-2 parts of lauroyl peroxide, performing reaction for 1-5h at 50-100 DEG C and under the normal pressure, and drying an obtained product to obtain the water-absorbent high polymer material.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a medicine bottle. Background technique [0002] In daily life, hygroscopic agents such as bottled solid and powder reagents, medicines, and dry powder culture media for microbiology often undergo deliquescence, agglomeration, or oxidative deterioration to varying degrees after unpacking and cannot be used any longer. cause a lot of waste. In the existing technology, three methods are mainly used for sealing; the first method is to place a desiccant in the bottle, or set a drying room for placing a desiccant bag in the bottle cap, and remove the desiccant in the medicine bottle through the adsorption of the desiccant. Moisture, but this method needs to add additional desiccant. Although the drying effect of this method is good, the additional desiccant increases the cost of the medicine, takes up the limited space in the medicine bottle, and increases the overall transportation w...

cause a lot of waste

In the existing technology, three methods are mainly used for sealing; the first method is to place a desiccant in the bottle, or set a drying room for placing a desiccant bag in the bottle cap, and remove the desiccant in the medicine bottle through the adsorption of the desiccant. Moisture, but this method needs to add additional desiccant. Although the drying effect of this method is good, the additional desiccant increases the cost of the medicine, takes up the limited space in the medicine bottle, and increases the overall transportation weight, so it is not necessary It is conducive to the reduction of production and transportation costs; the second is to seal the bottle mouth with an aluminum film, and the aluminum film needs to be uncovered to take out the material during use. With the aluminum film uncovered, the sealing effect cannot be guaranteed again. Membrane sealing adds a process and increases the workload; the third most commonly used method is to use the cork method, which is sealed by inserting the cork into the bottle mouth, but the sealed cork is not easy to take out, and tools are needed
