- the present invention relates to a material having a deodorizing function and a method for producing the same, and more particularly to a low-cost and general-purpose material having a disinfecting and deodorizing function and a method for producing the same using at least a part of waste materials.
- the material having a sterilizing and deodorizing function of the present invention is, for example, formed into a powdery form, and has a core portion or a coating layer portion of an animal excrement disposal material having a coating layer, or a pet sheet, a disposable diaper, a milk pad. It can be used as a material having a deodorizing function in the absorbent part of the pad or urine absorbing pad.
- the material having a deodorizing function of the present invention is formed into a powder form, placed in a container, and provided with a filter for a cooling / heating device, a filtering agent for hot water circulating in a bathtub, a shoe insole, or an appropriate material. It can be formed into a shape or put in a container and used for refrigerators, indoors, toilets, etc. Further, the present invention can be mixed with paper stock together with a sizing agent, filler and the like in the papermaking process, mixed with paper, and used for wallpaper and shoji paper.
- the present invention relates to a granular excrement disposal material having a deodorizing function for humans and / or animals and a method for producing the same, particularly to a material collected from household goods or a material collected from said household goods and
- the present invention relates to a granular excrement disposal material having a deodorizing function for humans and / or animals, made of waste material, and a method for producing the same.
- Granular excrement disposal materials for animals such as livestock and pets include inorganic materials such as sand, bentonite and zeolite, organic waste materials such as pulp for papermaking, coffee extraction residues, tea husks, It is manufactured by using organic waste materials such as pulp sludge as raw materials, mixing these materials with a water-absorbing resin, and forming them into small lumps or granules.
- Such granular excrement disposal materials are compounded with deodorant materials in order to remove the smell of excretions after use.
- indoor odor components include nitrogen compound odor components such as ammonia and trimethylamine, and sulfur odor components such as hydrogen sulfide and methyl mercaptan.
- a material having a deodorizing function used to remove these odor components it has a deodorizing function having an adsorption function of activated carbon, zeolite, or the like which adsorbs and removes these odor components.
- a deodorizing function having an adsorption function of activated carbon, zeolite, or the like which adsorbs and removes these odor components.
- the deodorizing ability of the material having the deodorizing function decreases as the deodorizing continues.
- it is necessary to regenerate the material with the reduced deodorizing function but in this regeneration process, the odor component once adsorbed is desorbed and released.
- the odor re-emerges which is a problem.
- a deodorant material for removing such an odor component by a chemical reaction a material having a deodorant function containing a complex such as copper or zinc, a basic compound or a hydroxide compound has been proposed (for example, And Japanese Patent No. 25557064).
- materials having a deodorizing function used here include, for example, silver nitrate, copper sulfate or zinc sulfate, or a basic compound thereof, or silver hydroxide, copper hydroxide or zinc hydroxide.
- the metal compound must be supported on cellulose fiber so as not to be easily eluted or detached from the cellulose fiber, and is fixed by reacting with the cellulose fiber modified with a carboxymethyl group.
- the fiber materials such as pulp or cellulose and fixing means such as carboxymethyl cellulose and other stabilizers used here are relatively expensive, so that materials having a deodorizing function are expensive. Its use is limited due to its price, and it has been a problem in providing materials with general-purpose deodorizing functions.
- the copper ions are bound to carboxmethylated cellulose, in the step of binding the copper ions to the carboxylated methylated cellulose, generation of a reaction waste liquid and a washing waste liquid is inevitable. This requires a large amount of money, which is a problem.
- the present invention provides a deodorizing function of copper sulfate or zinc sulfate having a deodorizing function, a basic compound thereof, copper hydroxide or zinc hydroxide, or a mixture of two or more of these metal compounds.
- the purpose is to provide inexpensive granular excrement disposal materials held as materials.
- the present invention provides an inexpensive granular excrement disposal material having a deodorizing function that does not require an operation of binding a metal compound having a deodorizing function to cellulose and a waste liquid treatment operation related to the operation. It is intended to be.
- Still another object of the present invention is to solve the problem related to the material cost of the conventional material having a deodorizing function. Disclosure of the invention
- the present inventors have impregnated or attached copper ions or the like having a deodorizing function to the surface of the coated granules by spraying or the like, and by drying, do not generate waste liquid.
- the present inventors have discovered that it is possible to provide a coated granulated product having a deodorizing function without dissolving a metal compound having a deodorizing function such as a copper compound, and have led to the present invention.
- the present inventors have found that paper powder having a relatively fine particle size, for example, a paper powder having a relatively fine particle size such as a pulp classified product containing a small amount of a water-absorbent resin, is a copper or zinc complex, or a basic compound.
- the present invention uses a classified product mainly containing pulp, which is separated and recovered by classification from waste products such as defective products generated during the manufacture of sanitary goods such as disposable diapers and cutting waste generated during cutting, and Defective thin paper, cut waste, and other waste paper materials are used as the raw material, and the crushed paper waste material is impregnated with copper or zinc or a water-soluble compound of copper and zinc. It is an object of the present invention to provide a relatively inexpensive material having a deodorizing function, in which zinc or copper and a water-soluble compound of copper and zinc are insoluble in water and retained in paper powder, thereby saving material costs and a method for producing the same. .
- the present invention provides a paper powder and a copper compound or A material having a deodorizing function characterized by having a lead compound, a copper compound, and a zinc compound.
- the present invention also provides a paper powder, and lipoxymethylcellulose fixed to the paper powder.
- the present invention relates to a material having a deodorizing function characterized by having a copper or zinc compound or a copper and zinc compound contained and held in the carboxymethylcellulose.
- a water-insoluble complex of zinc, a base compound or a hydroxide compound or a water-insoluble complex of copper and zinc, a base compound or a hydroxide compound wherein the complex, the base compound or the hydroxide compound is A material having a deodorizing function characterized by being held by paper dust; and the present invention further comprises: paper dust; carboxymethylcellulose fixed to the paper dust; A water-insoluble complex of copper or zinc, a base compound or a hydroxide compound, or a water-insoluble complex of copper and zinc, a base compound or a hydroxide compound, wherein the complex, the base compound or the hydroxide compound Is a material having a deodorizing function characterized by being contained and held in the carboxymethyl cellulose.
