Description

Manufacturing method of powder using natural material and highly polymerized natural compound manufactured by the same}

The present invention relates to a method for producing natural polymer powder using natural materials and a powder manufactured by the method.

A method for producing a powder composed of fine particles is known. Due to the recent emergence of environmental problems and interest in health promotion, many attempts have been made to develop powders containing natural materials. Most of these are related to cosmetics or mask packs that come into direct contact with the human body.

The range of application of natural polymer powder using natural materials is infinite. As an important natural material, there is a kind of hemp.

Hemp fiber has been used as a raw material for textiles since the beginning of human history, and there are 50 to 60 types of it in terms of botanicals. For medical purposes, flax, ramie (ramie), hemp, etc. are used. Manila hemp, sisalma, etc. are used for fishing nets or ship ropes, and jute is used for packaging. The classification of hemp fibers includes hemp, flax, hemp, jute belonging to bark fibers, manila hemp, sisal hemp, and New Zealand hemp belonging to leaf fibers, and palm fibers belonging to fruit fibers. and other fibers (其他纖維), such as rice straw and king bone.

Hemp fibers are common in that they are long, rough, and hard. In Europe, each is given a unique name, but in the East, they are collectively referred to as hemp fibers. Since hemp fibers are rough and hard, they collectively belong to hard fibers. On the other hand, flax, jerma, and jute, which are relatively flexible, are classified as soft hemp, and those that are more hard, such as manila and sisal, are classified as hard hemp.

Hemp (大麻) is usually called hemp and is produced in Korea in large quantities. Its origin was India and the Middle East, but it has excellent self-sustainability and is now cultivated regardless of climate, whether it is hot or cold. This is proved by the fact that the current main production area includes all regions of Europe including Russia, the United States, and the Asian region. The fiber is rough and lacks flexibility, so it is not used much as a fabric, but its durability and water resistance are strong, so it is used for various industrial purposes such as traditional clothes, funeral clothes, parts of veterinary clothes, mosquito nets, fishing nets and ropes, hoses, and firefighting related equipment. It is used a lot.

Manila hemp is native to the Philippines and is locally called Abaca. Inflexible ones are used for ropes, anchor lines for ships, etc., and are especially used for power transmission because they are resistant to sunlight and have a light specific gravity. Compared to hemp rope of the same thickness, the strength is about 1.2 times and the specific gravity is about 30% lighter. The light colors of good quality are spun for textiles and used for handbags and clothes, etc., and the finest and most delicate ones are used to make textiles for upholstery. Very low-grade products are also used as raw materials for paper.

Regarding hemp fiber, for example, Patent Publication No. 2011-134987 discloses organic natural powders such as jute, hemp, flax, bamboo, hemp, sisal, rice straw, rice hull, wood flour, and green tea, which are natural plant materials, as biodegradable resins, petroleum A bio-composite materialization technology is disclosed that is added to count paper, etc., and then commercialized through an extrusion or injection process. This process includes a pulverization step of wet or dry pulverization of natural powder to a size of 200 μm or less using a fine pulverizer, a drying step of drying the pulverized natural powder, a selection step of sorting the dried natural powder by particle size, and the selected natural It consists of a step comprising a melt extrusion mixing step of producing a pellet shape by melt extrusion mixing the powder using a general-purpose plastic including PP, PE, PVC, EVA, Nylon, and PET using an extrusion kneader. The product of this patent discloses that it is used as an eco-friendly material for indoor interior materials for construction, electronic product cases, and automobile interior materials. However, although this patent discloses hemp, flax, and jute, it considers them as one of the materials constituting natural powder and does not pay attention to the inherent properties of hemp products.
