COMPOSITE POWDERY BODY WHICH EMITS NEGATIVE ION AT HIGH EFFICIENCY, COMPOSITE POWDERY BODY DEPOSIT, AND ITS MANUFACTURING METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a high efficiency negative ion emitting composite powdery body which demonstrates a functional effect such as deodorization and an antibacterial function, and to provide a composite powdery body deposit and its manufacturing method. PSOLUTION: A charcoal-based powdery body is added to a tourmaline powdery body. The composite mixing ratio of the tourmaline powdery body and the charcoal-based powdery body is 1 to 20:99 to 80. A high molecular material (e.g. a foaming material or a chemical fiber material) such as a thermoplastic and/or thermosetting elastomer material is added to the composite powdery body, and both of them are melted, and this composite powdery body deposit product is manufactured. The tourmaline powdery body may be an iron tourmaline, a lithia tourmaline, a manganese-containing lithia tourmaline, a cesium tourmaline or a magnesium tourmaline. The charcoal-based powdery body may be a bamboo charcoal, a coconut charcoal, an activated charcoal or a wood charcoal. The average powdery body particle size is 0.3 to 1 m for the tourmaline, and 5 to 20 m for the charcoal powdery body. Thus, a large amount emission of negative ions, and functional effects such as deodorization and the antibacterial function are demonstrated by forming a high piezoelectric, electrothermal function or related physical properties by the synergistic characters of the composite powdery body.
