(Industrial Application Field) The present invention relates to a deodorizing resin composition, and more specifically, an object of the present invention is to provide a deodorizing molded article suitable for packaging various malodorous articles. (Prior Art) Conventionally, deodorizing agents for various sources of malodors have been widely used, and in order to package various malodorous articles, non-permeable plastic films, aluminum foils, metal Containers, glass containers, etc. are used. (Problems to be Solved by the Invention) Packaging using conventional packaging materials with no air permeability as described above can prevent the bad odor of the contents from evaporating, but when the containers are opened, It is inconvenient to handle because the foul odor that is pervading the room evaporates outside all at once. As a result of intensive research to solve the above-mentioned drawbacks of the prior art, the inventor of the present invention has developed a plastic film,
When manufacturing molded products such as plastic sheets or plastic containers, when a specific substance is included in the thermoplastic resin used, the resulting molded product, for example, a packaging material, has excellent deodorizing properties, and the above-mentioned The present invention was completed based on the finding that the drawbacks of the prior art such as the above can be solved. (Means for Solving the Problems) That is, the present invention provides thermoplastic resins ranging from 99.9 to 50
In a deodorizing resin composition consisting of parts by weight and 0.1 to 50 parts by weight of a deodorizing component, the deodorizing component consists of a calcium compound selected from the group consisting of calcium oxide, calcium hydroxide, and calcium peroxide and an aluminum sulfate. This is a deodorizing resin composition characterized by: Next, to explain the present invention in more detail, the present inventor has conventionally conducted various studies on deodorizing resin compositions and molded products obtained therefrom, but by blending a specific combination of deodorizing compounds,
The present invention was completed based on the finding that resin compositions and molded articles that exhibit a remarkable synergistic effect can be obtained compared to when each deodorizing compound is used alone. The thermoplastic resin used in the present invention includes polyolefin resins such as polyethylene and polypropylene, polyvinyl chloride, which have been conventionally used for molding various molded products such as plastic films, plastic sheets, plastic containers, fibers, etc. These thermoplastic resins are synthetic or modified thermoplastic resins such as vinylon, polystyrene, polyamide, polyester, and cellulose acetate. All of these thermoplastic resins are easily available on the market and can be used. It may be solid or liquid such as paste. The calcium compound that is the deodorizing component used in the present invention is selected from the group consisting of calcium oxide, calcium hydroxide, and calcium peroxide. The aluminum sulfate used in the present invention is
Aluminum sulfate [Al 2 (SO 4 ) 3 ] and potassium aluminum sulfate [KAl(SO 4 ) 3 ] are preferred, with aluminum sulfate being particularly preferred. The main feature of the present invention is that the above calcium compound and aluminum sulfate are used in combination as a deodorizing component. That is, it is known in the prior art that ferrous salts are used as deodorizing ingredients, but when such ferrous salts are kneaded into thermoplastic resins, etc., the processing temperature of the thermoplastic resins Because of the high ferrous salt, the ferrous salt discolored and colored the thermoplastic resin brown, reducing the deodorizing effect and significantly lowering the commercial value of the molded product. In addition, aluminum salts are sometimes used alone as a deodorizing component, but although aluminum salts are effective in deodorizing amine-based malodorous components such as ammonia, they have little effect on sulfur-based malodorous components such as hydrogen sulfide. It had no effect. In the present invention, a calcium compound is used instead of such a ferrous salt, and aluminum sulfate is used in combination with the calcium compound to reduce the high cost when kneading a deodorizing component into a thermoplastic resin. Even at processing temperatures, the deodorizing component does not impair its deodorizing effect, and there is no brown discoloration of the deodorizing component, and together with the deodorizing effect of aluminum sulfate, it deodorizes not only amine-based malodorous components but also sulfur-based deodorizing components. It has been found that the deodorizing effect is greater than the sum of the unique deodorizing effects of each compound. In the deodorizing component made of calcium compound and aluminum sulfate as described above, the ratio of their usage is also important, and if the total amount is 100 parts by weight,
The proportion of the calcium compound is 10 to 90 parts by weight, and the aluminum sulfate is 90 to 10 parts by weight, and in such a combination and blending ratio,
The objectives of the invention are best achieved. The deodorizing resin composition of the present invention has the above two components as essential components, but it also includes various conventionally known additives for resins, such as colorants, fillers, extender pigments, plasticizers, stabilizers, and ultraviolet absorbers. Agents and the like can be added as desired. The deodorizing resin composition of the present invention can be obtained by simply mixing the above components, or may be obtained by melt-kneading the mixture and granulating it into pellets or the like. Furthermore, it may be in the form of a masterbatch containing a high concentration (for example, 10 to 50% by weight) of the deodorizing component for later use by diluting with an additive-free thermoplastic resin. The deodorizing resin composition of the present invention as described above is useful for producing the deodorizing molded article of the present invention. The deodorizing molded article of the present invention is a molded article of the above-mentioned deodorizing resin composition in various shapes, for example, a packaging material made of a plastic film or sheet, or an arbitrary molded article formed by molding the deodorizing resin composition by various methods. It is a molded product such as a shaped container. Forming of such films, sheets, containers, etc. is carried out using conventionally known inflation devices, presses,
It can be carried out using various conventionally known conditions using a calendar, an extrusion molding machine, a spinning machine, a blow molding machine, an injection molding machine, a vacuum molding machine, etc.
The deodorizing molded article of the present invention can be easily obtained. (Action/Effect) Conventionally, it has been known to use ferrous salt as a deodorizing component, but when such a deodorizing component is kneaded into a thermoplastic resin, etc., the processing temperature of the thermoplastic resin must be Due to the high ferrous salt, the ferrous salt discolored and colored the thermoplastic resin brown, reducing the deodorizing effect and significantly lowering the commercial value of the resin molded product. In the present invention, a calcium compound is used instead of such a ferrous salt, and aluminum sulfate is used in combination with the calcium compound to reduce the high cost when kneading a deodorizing component into a thermoplastic resin. Even at processing temperatures, the deodorizing component does not impair its deodorizing effect, does not discolor to brown, and can exhibit a deodorizing effect that is greater than the sum of the deodorizing effects of calcium compounds and aluminum sulfates. It also showed a sufficient deodorizing effect against sulfur-based malodorous components. Therefore, when molded articles, such as packaging materials, made of the deodorizing resin composition of the present invention are used to package articles with strong malodors, such as fish and fish products, various pickles, and various other foods, the odor emitted from the molded articles, such as packaging materials, can be reduced. Since the packaging material itself absorbs the odor, strong odor will not spread to the surrounding area even when these packages are opened. or,
For the same reason, it is also effective for packaging not only food but also various household garbage, factory waste, etc. In addition to the above-mentioned packaging materials, the deodorizing resin composition of the present invention can also be used in deodorizing molded articles, such as granular deodorizing agents, in places where foreign odors or malodors occur or accumulate.
It is useful as a raw material for deodorizing wall coverings, floor coverings, deodorizing fibers, textiles, and other molded products. Next, the present invention will be explained in more detail with reference to Examples. In the text, parts or percentages are based on weight unless otherwise specified. Example 1 99 parts of low-density polyethylene was blended with 1 part of a mixture of calcium oxide and aluminum sulfate at a weight ratio of 10:3, mixed in a mixer, and transferred to a 40 mm extruder (L/D = 28, CR = 3.1, The mixture was kneaded using a screw with a dullage, a cylinder temperature of 130° C., and a screw rotation speed of 70 rpm) to obtain a pellet-shaped deodorizing resin composition of the present invention. Next, the above deodorizing composition was passed through an inflation device (30 mm extruder, 50 mm inner diameter inflation die, cylinder temperature 140°C, screw rotation speed).
60 rpm) to obtain a polyethylene film with a wall thickness of approximately 50 microns. The deodorizing properties of this deodorizing sheet were investigated and the results were as follows. At the same time, the appearance of the obtained film was examined, and those that were not colored were marked as ○, and those that were colored brown were marked as x. Ammonia deodorization test The above deodorization sheet was cut into 50 mm x 200 mm, and one cut film was placed in a 300 ml Erlenmeyer flask, then 10μ of 28% ammonia water was added, and the opening was sealed with parafilm.
