Description
Technical field
The present invention relates to deoxidier, be specifically related to a kind of difunctional quick dehumidifying/deoxidizing agent and preparation method thereof.
Background technology
In recent years, the strong request at improving the food antiseptic fresh-keeping effect makes foodstuff package inside be in hypoxemia and low wet condition at short notice, thereby the inhibition Food Oxidation goes bad or makes moist.Specifically, be with quick dehumidifying/deoxidizing agent with pack into the inside of foodstuff package of food, to reduce foodstuff package inner residual oxygen concentration and humidity, guarantee that food can be not putrid and deteriorated.
The deoxidier that is formed by organic class material and the deoxidier that is formed by mineral-type materials are arranged at present.Consider from cost, security aspect, mainly use the iron series deoxidizers of inorganic material.In the application of reality, iron series deoxidizers and oxygen reaction must have enough moisture, and the water deficient in the atmosphere is so that oxygen drops to lower concentration, so need add a spot of water in the deoxidation component usually; And in order to guarantee that deoxidier has the dual-use function of dehumidifying, deoxidation, also need to add the water imbibition material.Add water for the deoxidation component, can influence the effect of dehumidifying, the water imbibition material also can influence the effect of deoxidation simultaneously.Therefore the most existing iron series deoxidizers has only the effect of deoxidation usually, and does not possess the function of dehumidifying.This has limited the use of such deoxidier to a great extent, especially aspect the preservation of article such as dried food and nuts food, tealeaves.Though it is difunctional that some iron series deoxidizers has the dehumidifying deoxidation at present, as Chinese patent " bactericidal dehydration and deoxidation preserving agent and preparation method thereof " (publication number: CN101199360A, open day: on June 18th, 2008), announced that a kind of iron is but that dehydration and deoxidation preserving agent this patent have only been listed the potential scope of application of dehydration and deoxidation agent, lacks concrete dehumidifying deoxidation data.。
Summary of the invention
Purpose of the present invention is exactly in order to solve the problems referred to above that deoxidier of the prior art exists, by a large amount of experiments, developed a kind of oxygen that can remove effectively in the atmosphere, can remove the difunctional quick dehumidifying/deoxidizing agent of the moisture in the atmosphere again effectively, this difunctional dehumidifying/deoxidizing agent production technology is simple, raw material is easy to get, and is with low cost, is convenient to industrialization promotion.
Technical scheme of the present invention is as follows: iron and copper sulphate reaction generate copper, original position forms copper iron galvanic cell, oxygen in so just can fast Absorption atmosphere consumes the moisture in the deoxidation component simultaneously, thereby the water influence dehumidifying of having alleviated in the deoxidation component has also been alleviated the water imbibition material to the oxygen uptake Effect on Performance.Slaine such as copper chloride, chloroplatinic acid and iron effect and copper sulphate have similar principle.Experimental result shows that adding the deoxidation component that constitutes behind copper sulphate, chloroplatinic acid or the copper chloride can utilize moisture efficiently, reaches the effect of quick deoxidation; Also suppress simultaneously the moisture in the dehumidifying component absorption deoxidation component, alleviated the influence of dehumidifying component to deoxidation speed.
Difunctional quick dehumidifying/deoxidizing agent of the present invention is made up of deoxidation component and dehumidifying component, and described each component of deoxidation component and quality percentage composition (being the percentage that each constituent mass accounts for the dehumidifying/deoxidizing agent quality) thereof are as follows:
Iron powder 32%～47%, auxiliary agent 0.03%～1%, catalyst 3%～7%, filler 9%～18%, sulfuric acid 0.3%～0.5%, water 7%～10%, wherein auxiliary agent is metallic salt;
The quality percentage composition of described dehumidifying component is 30%～38%.
Iron powder is deoxidation component main body, is preferably 100～200 purpose reduced iron powder or cast iron powders.
Described metallic salt is the salts substances of copper or acids or the salts substances of noble metal, and wherein the salts substances of copper is cupric sulfate pentahydrate or copper chloride dihydrate, and the acids of noble metal or salts substances are chloroplatinic acid, gold chloride, palladium bichloride etc.
Described catalyst is more than one in sodium chloride, potassium chloride or the calcium chloride.
Described filler is two or more in active carbon, silica, kaolin, diatomite or the carbon fiber.
Described dehumidifying component is more than one in calcium oxide, the silica gel.
The preparation of above-mentioned difunctional quick dehumidifying/deoxidizing agent, its step is as follows:
1) by proportioning catalyst, auxiliary agent, the concentrated sulfuric acid and water are mixed after, stir rapidly;
2) add iron powder by proportioning in the step 1) after, stir 0.5～5min, iron powder is activated, and constitutes galvanic cell with metal in the auxiliary agent;
3) press proportioning again to step 2) the middle filler that adds, stir, obtain the deoxidation component;
4) with after the sealing of deoxidation component, put into obturator together with the dehumidifying component again and seal, namely obtain dehumidifying/deoxidizing agent.
Difunctional quick dehumidifying/deoxidizing agent provided by the present invention can absorb oxygen and the moisture of removing in the atmosphere.
Compared with prior art, the present invention has the following advantages:
