Problems solved by technology

[0003] There are many methods for making desiccants in the present technology, which can basically meet people's needs, but for some special items, the hygroscopic performance is extremely high, and the general moisture absorption rate of common desiccants is only below 40%; Chinese patent CN101249418 discloses A desiccant with high moisture absorption rate has been developed. Although its maximum moisture absorption can reach more than 200% of its own weight at a temperature of 40°C and a humidity of 90%, this mineral desiccant has no fragrance and is used in some high-end clothes, The storage and use of leather goods, stamps, cameras, pianos, computers, and audio-visual facilities is difficult to meet individual needs; and some desiccants based on scented silica gel have insufficient moisture absorption rate and cannot be used for a long time, so today's desiccants can no longer meet the requirements. need

Embodiment 1

[0030] A desiccant contains the following components and weight percentages: 40% of anhydrous magnesium chloride, 5% of activated carbon, 45% of chitosan, 5% of Pangpeng essential oil, 2% of peppermint essential oil, and 3% of lavender essential oil.

[0031] The preparation method of Pangpeng essential oil is as follows: add distilled water to fresh Pangpengxiang according to the ratio of material to liquid 1:10, soak for 4 hours, shake intermittently during the soaking process, conduct steam distillation after soaking, and end the distillation after 6 hours of extraction , collect the essential oil, and dry it with anhydrous sodium sulfate to obtain the Bangpeng essential oil.

[0032] The preparation method of peppermint essential oil is: put peppermint into a container, heat it from below to generate steam, the essential oil of peppermint evaporates with the steam, and the water vapor containing essential oil is collected and cooled into a liquid, according to the specific ...

Embodiment 2

[0037] A desiccant contains the following components and weight percentages: 30% of anhydrous magnesium chloride, 9% of activated carbon, 56% of chitosan, 3% of Pangpeng essential oil, 1% of peppermint essential oil, and 1% of lavender essential oil.

[0038] The preparation method of Pangpeng essential oil is as follows: add distilled water to fresh Pangpengxiang according to the ratio of material to liquid of 1:15, soak for 3 hours, shake intermittently during the soaking process, conduct steam distillation after soaking, and end the distillation after 6 hours of extraction , collect the essential oil, and dry it with anhydrous sodium sulfate to obtain the Bangpeng essential oil.

[0039] The preparation method of peppermint essential oil is: put peppermint into a container, heat it from below to generate steam, the essential oil of peppermint evaporates with the steam, and the water vapor containing essential oil is collected and cooled into a liquid, according to the specif...

Embodiment 3

[0044] A desiccant contains the following components and weight percentages: 35% of anhydrous magnesium chloride, 7% of activated carbon, 50% of chitosan, 4% of Pangpeng essential oil, 2% of peppermint essential oil, and 2% of lavender essential oil.

[0045] The preparation method of Pangpeng essential oil is as follows: add distilled water to fresh Pangpengxiang according to the material-to-liquid ratio of 1:20, soak for 2 hours, shake intermittently during the soaking process, perform steam distillation after soaking, and end the distillation after 6 hours of extraction , collect the essential oil, and dry it with anhydrous sodium sulfate to obtain the Bangpeng essential oil.

[0046] The preparation method of peppermint essential oil is: put peppermint into a container, heat it from below to generate steam, the essential oil of peppermint evaporates with the steam, and the water vapor containing essential oil is collected and cooled into a liquid, according to the specific gr...

Abstract

The invention discloses a drying agent and a preparation method thereof. The drying agent is prepared from the following components in percentage by weight: 30-40% of magnesium chloride, 7-9% of activated carbon, 45-56% of chitosan, 3-5% of pelargonium odoratissimum essential oil, 1-2% of mint essential oil, and 1-3% of lavender essential oil. The components are directly and uniformly mixed so that the drying agent can be obtained. The drying agent concurrently has the effects of moisture absorption, bacterium resistance and incensing, under the condition of the temperature being 30 DEG C and the humidity being 90%, after 15 days, the moisture absorption of the drying agent can reach 380% or above of the self weight of the drying agent, and besides, no liquid water permeates out.

Description

technical field [0001] The invention relates to a desiccant and a preparation method thereof, in particular to a fragrance desiccant containing Pangpeng essential oil and a preparation method thereof. Background technique [0002] With the improvement of the level of industrial manufacturing, desiccant is used in all walks of life. Economic development promotes the increase of people's clothes and their dependence on tools. They need to be dried during storage and transportation. [0003] There are many methods for making desiccants in the present technology, which can basically meet people's needs, but for some special items, the hygroscopic performance is extremely high, and the general moisture absorption rate of common desiccants is only below 40%; Chinese patent CN101249418 discloses A desiccant with high moisture absorption rate has been developed. Although its maximum moisture absorption can reach more than 200% of its own weight at a temperature of 40°C and a humidit...
