Difunctional deoxidier capable of quickly dehumidifying and preparation method thereof

Abstract

The invention discloses a difunctional deoxidier capable of quickly dehumidifying and a preparation method thereof. The deoxidier capable of quickly dehumidifying contains deoxidizing components and dehumidifying components which respectively account for the deoxidier capable of quickly dehumidifying in percentage by mass: 32 percent-47 percent of iron powder, 0.03 percent-1 percent of auxiliaries, 3 percent-7 percent of catalyst, 9 percent-18 percent of filler, 0.3 percent-0.5 percent of sulfuric acid, 7 percnet-10 percent of water, and 30 percent-38 percent of dehumidifying components. The preparation method comprises the following steps: after mixing the catalyst, the suxiliaries, the concentrated sulfuric acid and the water in proportion, quickly stirring evenly; adding the iron powder and stirring continuously, so that the iron powder is activated to form a primary battery with metal in the auxiliaries; adding the filler, and stirring evenly to obtain the deoxidizing components; and finally, after sealing the deoxidizing components, and putting the deoxidizing components and the dehumidifying components in a sealing body for sealing to obtain the deoxidier capable of quickly dehumidifying. The difunctional deoxidier capable of quickly dehumidifying is suitable to be widely used in food storage and goods storage in other fields; and the preparation method has simple process, obvious effect and low cost.

Description

technical field [0001] The invention relates to a deoxidizer, in particular to a double-functional fast dehumidification deoxidizer and a preparation method thereof. Background technique [0002] In recent years, in response to the strong demand for improving the antiseptic and fresh-keeping effect of food, the interior of food packaging is kept in a low-oxygen and low-humidity state in a short period of time, thereby inhibiting food from oxidative deterioration or moisture. Specifically, the fast dehumidifying and deoxidizing agent is packed into the inside of the food package together with the food, so as to reduce the residual oxygen concentration and humidity inside the food package and ensure that the food will not be spoiled. [0003] Currently, there are deoxidizers made of organic materials and deoxidizers made of inorganic materials. In consideration of cost and safety, iron-based deoxidizers made of inorganic materials are mainly used. In practical applications, ...

This largely limits the use of this type of deoxidizer, especially in the preservation of dry food, tea and other items

Although some iron-based deoxidizers have dual functions of dehumidification and deoxidation at present, such as the Chinese patent "Bactericidal Dehydration Deoxidation Preservative and Its Preparation Method" (publication number: CN101199360A, publication date: June 18, 2008), an iron-based deoxidizer has been announced. Dehydration and deoxidation preservative, but the patent only lists the potential use range of dehydration and deoxidation agents, lacking specific dehumidification and deoxidation data
