Abstract

PURPOSE:To obtain a water purification agents which can be molded into various shapes according to the place and condition under which they are used and which prevent bags from being broken because no water permeable wrapping material is used by mixing thermoplastic resins with water purification agents at a specific ratio. CONSTITUTION:As a water purification agent composition, 100 pts.wt. of thermoplastic resins such as gum base, etc., composed mainly of polyvinyl acetate are mixed with 0.1-1000 pts.wt. of water purification agents such as active carbon, zeolite, etc. In this manner, since no water permeable wrapping material is used, there is no possibility of broken bag and molding of any shape is possible by molding process of thermoplastic resins, thereby making it possible to mold said composition into such shapes as that of muddler, straw, spoon, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a water purifier composition that can be molded into any shape.

[Prior art]

Tap water contains various organic substances, and chlorine is added for sterilization and disinfection. These organic substances and chlorine cause other bad odors such as musty odor, potassium chloride, and other odors, and further impair the taste of tap water.

Therefore, in order to remove these organic substances and #A elements, we created a water purification device by storing a water purification agent mainly composed of activated carbon or zeolite in a water permeable packaging material and sealing it. It has been used by putting it into a container (Japanese Utility Model Publication No. 49-37402). By such a method, organic matter and mounds contained in tap water can be easily removed.

[Problem to be solved by the invention]

However, since the water purifying device in which a water purifying agent such as activated carbon is housed in a water-permeable packaging material and sealed is tea bag-shaped, there is a drawback that accidents such as bag breakage are likely to occur during the production process.

Another problem was that a special device was required to fold the water-permeable packaging material into a tea bag shape.

[Means to solve the problem]

Therefore, the present inventors investigated water purifying agents that do not have the above-mentioned problems, and as a result, they proposed the present invention.

That is, the present invention uses 100 parts by weight of thermoplastic resin and 0 parts by weight of water purifying agent.
．． This is a water purifier composition characterized in that it consists of 1 to 1000 am.

In the present invention, both natural and synthetic thermoplastic resins can be used. The water purifying agent of the present invention is generally produced by melt-kneading a thermoplastic resin and a water purifying agent as described below. It is preferable to prevent the water purifying agent from deteriorating or cracking due to the heat applied during this melt-kneading process. For this purpose, it is preferable that the thermoplastic resin has a relatively low melting point, for example, preferably 140° C. or lower.

Thermoplastic resins suitably used in the present invention include polyolefins such as polyethylene and ethylene-propylene copolymers; polyvinyl acetate; ethylene-vinyl acetate copolymers; polyvinyl chloride: polyester, etc., and in particular , a gum base containing polyvinyl acetate as a main component is suitable.

As the water purifier which is the other component of the water purifier composition of the present invention, any known water purifier can be used without any restriction. For example, adsorbents such as activated carbon, zeolite, coral sand (also referred to as coral fossil); #A scavengers such as ascorbic acid, its potassium salt or sodium salt: sodium loamide, potassium chloride, calcium chloride.

Easily water-soluble inorganic salts such as magnesium chloride, sodium carbonate, and potassium carbonate; deodorizing agents such as plant extracts are used alone or in combination of two or more.

Plant extracts contain various components, and generally include chlorophyll components, flavonoid components, essential oil components, and residue components.

In the present invention, each of these components may be used alone (or may be used as a mixture).

In the present invention, it is preferable to use a combination of the above-mentioned adsorbent and a chlorine scavenger as a water purifying agent, and it is more preferable to use this in combination with a water-soluble inorganic soil and/or a deodorizing agent.

The plants of the plant extract that can be used in the present invention are not particularly limited, and include, for example, Lauraceae, Camellia, Heliaceae, and Lamiaceae.

Examples include plants of the Chiridaceae family, the Mochitsufamily family, and the like. In particular, extracts from plants such as Lauraceae (Laurinaceae), Camellia (Camellia) and green tea, Lamiaceae (Lamiaceae) lavender, and Ilexaceae (Ginzaceae) have excellent deodorizing effects and are therefore preferably used in the present invention.

The amount of the above water purifying agent used varies depending on the type of water purifying agent. Based on 1001 parts by weight of the above-mentioned thermoplastic resin, the amount of adsorbent is 1 to 500 parts by weight, preferably 10 to 100 parts by weight.
Parts by weight, mound trapping agent: 0.1-300 M parts, preferably 1-100 parts, easily water-soluble inorganic salt: 0.1-100
Parts by weight, preferably 1 to 10 parts by weight, and 0.1 to 10 parts by weight of deodorizer
100 parts by weight, preferably from 1 to 10 parts by weight. When each of these components is used alone as a water purifying agent, the amount of the water purifying agent used is indicated by the amount of each of the above components used. In addition, when the above-mentioned components are combined to form a water purifying agent, the amount of each component used in one combination is expressed in terms of the amount of water purifying agent used.

The water purifier composition of the present invention is generally prepared by melt-mixing the thermoplastic resin and the water purifier, followed by molding. As the method of melt mixing and molding, any known method employed for general thermoplastic resins may be employed without any restriction. Therefore, the water purifier composition of the present invention can be molded into any shape. For example, molded into granules or tablets: Molded into a rod or cylinder and used as a stirrer or straw: The water purifier composition is molten on the surface of a molded object such as a rod, cylinder or plate. A layer made of the water purifying agent composition is formed on the surface of the molded object by applying a liquid or immersing the molded object in the water purifying agent composition in a molten state and cooling it. Use as a stirrer or straw: Form into the shape of a spoon or fork, etc.: Can be formed into a container for tap water, for example, a straw.

In order to increase the water purification effect of the water purifier composition of the present invention, the thermoplastic resin matrix is provided with continuous micropores, and tap water passes through the micropores and interacts with the water purifier present inside the thermoplastic resin matrix. Contact is preferred.

Thermoplastic Resin Ma) IJ Lux As a method for providing continuous microporous, a known foaming method is suitably employed. For example, a method in which the water purifier composition of the present invention is molded and then foamed under reduced pressure before being sufficiently cooled and solidified;
A method of adding a foaming agent to the water purifier composition of the present invention and foaming simultaneously with melt mixing can be mentioned.

〔effect〕

The water purifier composition of the present invention does not use a conventional water-permeable packaging material, so there is no risk of bag breakage, and there is no need to package the water-permeable packaging material inside the tea bag, so it has special characteristics. No equipment required.

Furthermore, since the water purifier composition of the present invention can be molded into any shape by a conventional thermoplastic resin molding method, it can be used anywhere where the water purifier is used.

Depending on the usage situation, it is possible to select and use products molded into various shapes such as stirrer straws, spoons, forks, and containers.
