Silver (Ag) has been used for various purposes in the form of a solution or powder for a long time as a representative substance with excellent antibiotic and antibacterial activity.However, when a small amount of silver is used as an antimicrobial agent, the silver ion action is lowered depending on the relative substance. It was very uneconomical to have sufficient properties of silver in order to increase the antibacterial effect because of its high price.

For example, when only silver ion antimicrobial agent was added in the production of the antimicrobial fiber, the discoloration of the composition due to the properties of the silver or the discoloration of the fiber and the increase of the production cost due to the significant cost increase were inevitable.

In addition, phyllosilicate minerals, elvan, hornblende, germanium, boulder, loess, kaolin, etc., which are known to have various special effects, are not easy to be applied to various industrial fields despite their inherent effects, Antimicrobial and antimicrobial deterioration from silver ion antimicrobial agents was not considered when they were mixed with substances such as antimicrobials to produce products with superior antimicrobial and antimicrobial potency.

The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to adsorb a zeolite or calcium phosphate having a crystal structure to completely adsorb it even in a small amount of silver and to perform excellent silver ion action. By adsorbing silver, a mixture having excellent antibiotic and antibacterial activity is produced.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

As is well known, zeolites form a wide variety of mineral phases under natural conditions and exhibit different properties depending on the species, both physically and chemically. The application of zeolites in the industrial sector is based entirely on the unique application mineral properties of these minerals, namely (1) cation exchange properties, (2) adsorption and molecular sieve properties, (3) catalytic properties, and (4) dehydration and ashing. It is due to absorption characteristics and the like.

Zeolite in the pure sense has a uniform "pore" of about 3 to 20 Å in size, with about 40 kinds of natural zeolites and about 80 kinds of synthetic zeolites. Currently, about 130 kinds of zeolites with various pore structures are known. have. Representative structures of frequently appearing zeolites are shown in FIG. 1. In the figures, A, F, ZSM-5, and Mordenite represent representative zeolites among various zeolites.

Spaces called pores 10, which are empty spaces in the zeolite framework, are filled with water molecules called zeolitic water and cations for charge offset, through which the silver ions (Ag ⁺ ) are adsorbed. do.

In addition to the zeolite, in the present invention, a mixed inorganic ion antimicrobial agent is prepared using calcium phosphate, also called lime phosphate.

Since calcium phosphate is tribasic acid, three types of calcium phosphate are known, such as calcium hydrogen phosphate, calcium dihydrogen phosphate, and tricalcium phosphate. In particular, calcium phosphate is often referred to as tricalcium phosphate.

Tricalcium phosphate (Ca3 (PO4) 2), also called tricalcium phosphate, is a colorless and amorphous powder that is insoluble in water but soluble in strong acids. It is also slightly soluble in water containing carbon dioxide, and monohydrate, dihydrate and pentahydrate are known. It is naturally produced as apatite and is widely distributed in the bones and soil of vertebrates and is a necessary element for plant growth. It is made by adding calcium salt solution and ammonia to the sodium phosphate solution. Used as additives in glazes, enamels, frosted glass, toothpaste, etc., and as a nutrient and antacid.

Next, the manufacture of the mixed inorganic ion antimicrobial agent used for this invention is examined.

First, the above-mentioned zeolite or calcium phosphate is powdered by a conventional method to adsorb 0.1 to 7% by weight of silver to 93 to 99.9% by weight of zeolite or calcium phosphate. In this case, zeolite is preferably used.

The mixed inorganic ion antimicrobial agent thus prepared is very excellent in the persistence of the antimicrobial and antimicrobial effects even when it contains a small amount of silver, and enables the production cost to be realized while suppressing discoloration of the composition.

Minerals used in the present invention are selected from natural minerals such as phyllosilicate minerals (mica), ganbanite, hornblende, germanium, gemstones, loess, and kaolin, which are known to have particular effects, and artificial synthetic minerals obtained therefrom.

The composite functional product according to the present invention is prepared by using minerals together with the mixed inorganic ion antimicrobial agent, and catering to some of the minerals known to act to promote blood circulation, UV protection, deodorization, anti mold, harmful electromagnetic waves, etc. The minerals are pulverized and calcined to remove foreign substances, and finely pulverized with a fine pulverizer with fine particles or mixed with a substrate with an ultrafine powder of 1 탆 or less mixed with a substrate by passing through a filter under pressure depending on the intended use. .

More specifically, the mineral of the present invention is a step of firing at 500 ° C to 1,200 ° C and then pulverizing the ultrafine powder to remove foreign matter as a basic process.

The pulverization process comprises the steps of crushing the particle diameter of each mineral to about 50㎛ 1, selectively fine grinding to the second 0.02㎛ according to the intended use, by mixing the finely ground powder with an appropriate amount of water in the wet It is also possible to add a step of passing the filter by pressure.

At this time, it is also possible to add a very small amount of zinc to the mixed inorganic ion antimicrobial agent for the purpose of active ionic action of silver ions, in this case 0.1 to 7% by weight of silver, zinc to 86 to 99.9% by weight powder selected from zeolite or calcium phosphate 0.1-7 weight% is mixed. However, when the mixed inorganic ion antimicrobial agent thus prepared is the human body, zinc is not added. Subsequently, one of natural minerals or synthetic synthetic minerals such as filosilicate minerals (mica-layered structure), elvan, hornblende, germanium, jadeite, loess, and kaolin is firstly ground to have a particle diameter of 50 μm (S103). ). Subsequently, the primary milled mineral powder is fired in a normal firing furnace at a temperature ranging from 500 ° C. to 1,200 ° C. (S105). At this time, the reason for firing the powder of the mineral is to remove impurities attached to the mineral, and also because the specific mineral is doubled in its properties by firing. Subsequently, the mineral powder, which has undergone the primary grinding and calcining, is selectively and precisely secondaryly pulverized to 50 to 0.02 µm (S107). Finally, 1 to 10% by weight of the mixed inorganic ion antimicrobial agent and 90 to 99% by weight of the secondary milled mineral powder are mixed (S109).
