Description

Method for manufacturing far-infrared radiation artificial wood and artificial wood manufactured using the same {Artificial lumber}

The present invention relates to a method for producing far-infrared radiated artificial wood, and to artificial wood manufactured using the same. More particularly, wood flour and synthetic resin of artificial wood are used as the main components. The present invention relates to a method of manufacturing far-infrared radiation artificial wood that provides a pleasant environment and provides antibacterial and deodorizing functions and to artificial wood manufactured using the same.

In general, construction materials for walking, such as hiking trails, trails, walkways or yards of detached houses are constructed. Such building materials include stone, wood, concrete, brick, and the like.

However, these building materials are difficult to mass-produce, and in the case of stone or wood, it is difficult to secure materials for mass production, and because the external shape is not constant, separate dimensioning is required for standardization.

Preserved wood, which we often use as a deck material, is mainly used as a timber material by pine wood, hamlock or hamper.

Preserved wood is produced as a preservative wood through the preservative treatment process, the predominant wood preservatives are chromated copper arsenate (CCA).

Preservatives used for preservatives are chemicals that do not decay. They contain highly toxic substances because they prevent the incubation of microorganisms and kill them when the insects that eat wood are eaten and die. And the like that may contaminate a flower or the like.

Since the substances included in the stapling tree contain chromium, arsenic, copper and the like and release harmful poisons, which are harmful to nature and the human body, legal regulations on these substances are increasingly being strengthened.

WPC (Wood Plastic Composite) using wood powder has been used as artificial wood to replace the wood preservation wood, but this also exposes the disadvantages such as surface hardness, screw coupling detachment, and change due to temperature change. In order to make environmentally friendly products with the reinforcement of, the composite materials of wood powder mixed with low density polyethylene (LDPE), polypropylene (PP), polystyrene (PS) or polyvinyl chloride (PVC) resin have been generally used.

However, the general purpose resins have a disadvantage in that surface hardness is weak after molding and an abnormality occurs in shrinkage rate due to temperature change, and a mixing ratio for increasing the bonding strength with the resin is greater than 1: 1 by weight due to the lack of viscosity of wood flour. It was possible to form.

In fact, almost all artificial wood (WPC) uses wood powder rather than wood fiber, which is made by crushing recycled materials such as chips, shavings, and sawdust into fine powders, which makes wood fibers difficult to process often with excellent composite properties. Rather than being used as a reinforcing agent, it is often used.

Far-infrared radiation is an electromagnetic wave, a kind of energy wave, which refers to light having a wavelength range of 0.76 to 1,000 microns. The band is called far infrared. Of these, far infrared rays of 6 to 1 micron wavelength are known to be the most beneficial to our lives.

Far infrared rays are transmitted by radiation, and have a characteristic of being activated by resonating and resonating with the wavelength of a material ball. Therefore, far infrared rays are directly and instantaneously transmitted to the object without heating the intermediate medium, and unlike visible or near infrared rays, the far infrared rays penetrate deeply into the body as well as the surface of the human body or material. Far-infrared radiation causes self-heating at the deep part of the material to uniformly heat the inside and outside of the material, thus enabling efficient heating of paints, foods, and the human body. Therefore, when the far infrared rays are irradiated to the human body or an object, heating can be performed within a short time without heat loss, so the energy saving effect is excellent. In addition, the far-infrared rays of the long wavelength due to low-temperature radiation not only gives a soft heating sense to the human body, but also enables comfortable heating without generating noise and odor, and there is no risk of fire.

The effects of far-infrared rays on the human body include temperature increase of subcutaneous depth, expansion of microvessels, promotion of blood circulation, enhancement of metabolism, increase of tissue regeneration ability, and excellent effects on gynecological diseases, nervous system diseases, and senile diseases. have. In addition, far-infrared rays have the functions of activating water molecules and regulating humidity to inhibit the activity of fungi and bacteria and to remove odors caused by the growth of microorganisms.

Since far infrared rays have excellent characteristics as mentioned above, they are widely used in real life, and recently, ocher, jade or elvan can be used to emit far infrared rays such as interior walls or floors used for building houses. By the way. These materials have the disadvantages of ultimately low health promotion effect due to the low far-infrared emissivity and radiation energy, and various other effects that do not meet expectations. Especially, it is not applied to artificial wood (synthetic wood) and thus provides far infrared There was a drawback that you can not enjoy the various effects.
