Definitions
- the present invention relates to a biodegradable resin composition which is decomposed in a natural environment while having the characteristics of a synthetic resin.
- Synthetic resins prepared from petroleum are not decomposed even at the after disposal natural environment and generate harmful substances and co 2 typified by the burning dioxin. Therefore, environmental pollution by wastes of general-purpose synthetic resin products has become a problem in recent years, and development of biodegradable resins that are degraded in the natural environment is being pursued due to the need for environmental protection. Also, in relation to producer liability, which is also imposed on companies that manufacture synthetic resin products, biodegradable resins incorporate a carbon recycling function, and as a product that anticipates dealing with such responsibility. It is expected.
- biodegradable resins are decomposed in the natural environment and return to the soil like natural materials, they are softened by heating like synthetic resins so that plastic flow occurs and they can be melt-formed into the desired shape.
- it because it is required to have the property of being possessed, it is necessary to have hydrophobicity, crystallinity, and hydrolysis resistance at room temperature, which are not found in natural materials. Therefore, as a biodegradable resin material that achieves balance between stability and degradability as a material, Japanese Patent Application Laid-Open No. 2001-332317 discloses the degradation of synthetic biodegradable resin.
- a technique that can be set to a desired level of stability and biodegradability by mixing a substance that accelerates a substance and a substance that suppresses a biodegradation speed at a predetermined mixing ratio.
- Such substances that accelerate the rate of biodegradation include starch derived from grains, etc., but in many cases, discoloration and coloration of the resin due to high temperature treatment and deterioration of physical properties occur. And, in order to secure the prescribed physical properties (performance), the amount to be kneaded is also limited. It was On the other hand, recently, many products in which functions have been added to resin materials themselves have been developed.
- a biodegradable resin molded product is compounded with a tea-derived substance, to which a deodorant, antibacterial, antiallergenic, antiallergenic one, antiger Functional biodegradable resin moldings having a function such as oxidation have been presented.

It aims to provide a high value-added biodegradable resin material that has realized and added useful functions, and a method for producing the same.
- solid particles of a predetermined particle size obtained by grinding a biodegradable resin composition and rice having an outer layer structure are bound by biodegradable resin.
- Such solid particles derived from rice contain multiple types of high molecular organic substances such as starch and cellulose, and have good bondability with biodegradable resin while maintaining a solid state of a predetermined particle size. It becomes easy to mix a large amount without deteriorating the physical properties of the biodegradable resin, and the manufacturing cost of the biodegradable resin composition can be reduced.
- the outer layer structure of rice is rich in high molecular weight organic substances other than starch and has a high bonding property with biodegradable resin, for example, from rice shavings and rice grinding waste solution residue in a non-washing rice plant, It is possible to use what is usually regarded as waste, such as the white eel produced and the residue of the rice mill manufacturing plant. And such biodegradable resin composition becomes a porous material in which fine solid particles derived from rice are combined, and exerts the effect of maintaining freshness and the effect of increasing negative ions.
- the outer layer tissue of rice means a tissue layer including the skin, seed coat, paste powder layer, and the outer part of the endosperm, which is the core part of the brown rice, which is called the cocoon layer.
- “Breath” refers to industrial residues left by filtering the waste solution generated when rice bran and rice outer layer are scraped and sharpened, and “freshness retention effect” refers to ripening of fresh food and fresh flowers, etc. It means the effect of preventing or delaying the deterioration of quality due to degeneration or rot.
- the solid particles of the predetermined particle diameter described above are mainly composed of the outer layer structure of rice.
- a biodegradable resin composition with particularly excellent physical properties can be obtained.
- this is made up of white straw or rice polishing waste liquid residue produced mainly in the brewing process, industrial wastes discharged from the brewing process and the non-washing rice manufacturing plant etc. are effectively used to prevent environmental destruction while further reducing the environmental damage. Cost reduction can be realized.
- the biodegradable resin composition described above is a mixture of functional organic matter of plant origin, the effect of the biodegradable resin composition described above can be enhanced or a new effect can be further added.
- the functional organic substance means an organic substance that exhibits useful functions such as freshness holding effect, antibacterial effect, and negative ion increasing effect.
- tea-derived substances that are known to have the effect of maintaining the freshness of functional organic matter derived from plants described above, bamboo-derived substances such as bamboo powder and bamboo extract, trees such as kelp, wood powder and tree extract, etc.
- a biodegradable resin composition comprising a combination of one or more of a derived material, a starch syrup, a rice bran, a harp derived material, and a kelp derived material. This makes it possible to produce a biodegradable resin composition having at least the effect of maintaining freshness, and to produce a high-value-added functional product having a plurality of functions.
- the heat resistance of the molded product can be enhanced along with the freshness holding effect, and if the silicon is added, the durability of the molded article is improved along with the freshness holding effect. be able to. 'Best mode for carrying out the invention
- the regrind waste solution residue of the non-washing rice production process is used.
- This is an industrial residue, mostly after rice bran has been removed from the raw material rice in a non-washed rice plant etc., and the waste solution obtained by water-washing it is deposited on a filter placed at the drainage port. It is a substance that is relatively low in lipids and rich in cellulose, and most of it is derived from the outer layer tissue of rice.
- the residue discharged from the sake brewing process of the sake brewing plant and the rice cracker plant can be used in the same manner.
- the composition of the outer layer tissue of rice varies depending on the type of rice and the difference in the layer depending on the depth from the surface
- dry rice flour itself White rice husk
- old rice that is considered to be disposed of can also be used effectively by crushing it to a predetermined particle size.
- the rice bran mentioned above has utility value as fertilizer and feed for livestock. Since the waste liquid from the rice polishing industry and its residue have almost no utility value until now, it will lead to environmental destruction such as water pollution if disposed in the river or the sea. It has been treated as industrial waste at a cost.
- Such washing waste liquid is dried and solidified and then crushed to obtain a predetermined uniform particle size, Mix in biodegradable resin.
- the solid particles are preferably in the range of 80 to 200 mesh from the viewpoint of securing the physical properties of the molded product.
