摘要： PURPOSE:To obtain a synthetic resin composition which can give a material with which plants such as flowers, vegetables and fruits can be preserved for a long time without any extra processing or complicated process, by mixing a styrene resin with a specified amount of an inorganic porous body. CONSTITUTION:This synthetic resin composition is prepared by mixing 100pts.wt. styrene resin with 0.5-30pts.wt. inorganic porous body. Examples of said styrene resins include rubber component-free usual styrene resins, rubber-modified polystyrenes, ABS resins, MBS resins and conjugated diene/aromatic vinyl block copolymers. Examples of said inorganic porous bodies include cristobalite, diatomaceous earth, activated clay, acid clay zeolite and silica gel, and they are used after adjusting their diameters to about 1-100mum.

摘要： PURPOSE:To obtain a synthetic resin composition which can give a packaging material which can preserve plants such as floweres, vegetables and fruits for a long time, by mixing a polyolefin resin except polyethylene with an inorganic porous material at a specified weight ratio. CONSTITUTION:100pts.wt. polyolefin resin (A) except polyethylene (e.g., polypropylene or polybutene-1) is mixed with 2-30pts.wt. inorganic porous material (B) to obtain the purpose synthetic resin composition. Examples of components B which can be suitably used include cristobalite, diatmaceous earth, activated clay, zeolite and silica gel each having micropores of a diameter of 10-1,000Angstrom . When a film obtained by molding this composition is used for packaging plants, it can preserve them for a long time without any additional processing because of its suitable air permeability.

摘要： PURPOSE:To obtain excellent shock absorptivity, rigidity and safety without thickening the thickness of a material, by preparing a laminated material, in which layers of elastic body of fiber-resin composite and layers of plywood are integrally laminated between a layer of woody surface material and a layer of unevenness-correcting body. CONSTITUTION:An elastic body layer of fiber-resin composite 4 made of soft resin and fiber and a layer of plywood 5 are laid respectively in plurality between a layer of woody surface material 2 and a layer of unevenness-correcting body 3. These layers are laminated to form an integrated material. Through the above processes, sufficient and excellent shock absorptivity can be secured even in a thickness roughly the same as conventional woody flooring materials and sufficient rigidity and safety as a flooring material can also be secured.

摘要： PURPOSE:To obtain an aromatic material emitting no aroma usually but emitting aroma upon heating, by compounding three components, that is, a carbonaceous substance such as graphite, a thermosetting resin such as a phenol resin and fragrance such as alpha-pinene as essential components. CONSTITUTION:Three components, that is, a carbonaceous substance selected from graphite such as natural graphite, carbon black such as furnace black, a carbon fiber and activated carbon, a thermosetting resin such as a phenol resin and fragrance, for example, hydrocarbonaceous fragrance such as alpha-pinene or alcoholic fragrance such as menthol are compounded as essential components. Subsequently, a porous substance increasing aromaticity, a plasticizer, a stabilizer, fire retardant or the like are added to three essential components to be sufficiently mixed therewith by a ball mill and the resulting mixture is molded by an arbitrary molding method such as calender molding or extrusion molding to prepare a molded product. By this method, an aromatic material excellent in heat resistance, having no aromaticity at the ambient temp. and developing aromaticity upon heating can be obtained and shows extremely marked industrial effects.
