Abstract: Wood is one of the materials most closely related to human beings. As a pure natural green environmental protection material, it has perfect properties. It can adjust the temperature and humidity in the room and adjust people’s psychological feeling. It has the functions of heat insulation, sound absorption, sterilization and extermination. In a sense, it can have a magical effect that can prolong human life. However, the excellent efficacy of wood itself is obvious when faced with huge health needs. Therefore, some scholars expect that wood can be compounded or modified in various ways to give it a wider range of health effects.
At this stage, the research and preparation of health?efficiency woods are mainly focused on the following aspects: (1) Health?care materials with anion?releasing effects, the preparation of which is mainly focused on the composite modification of natural ore and wood and the chemical modification treatment of modifiers. Introducing wood by impregnation, the preparation method is simple, but the negative ion release is relatively low, and there are defects such as high loss rate and reduced material strength. (2) Wood?based electromagnetic shielding health materials, the preparation methods mainly include composite method and high temperature carbonization method, in which the composite type includes surface coating type and internal filling type. The dry wood itself is an insulating material and does not have a conductive function, but the wood has a po?rous structure. By adding a conductive substance to the wood, the composite material has electromagnetic properties. Shielding energy efficiency. (3) Bacteriostatic health materials, mostly nano?silver ions and titanium dioxide modifiers with a bactericidal effect on the surface of wood, health care materials have significant antibacterial properties against to some representative bacteria which are harm to human health, and exhibits certain durability and stability. (4) Chinese herbal medicine compound health care material, often in traditional Chinese medicine extract way into the wood, or by directly placed in the daily use wooden finish powder medicine, or add in man?made board production process preparation way of Chinese native medicine ingredient care material, its simple and efficient way, can make full use of the medicinal value of Chinese traditional me?dicine. (5) The far?infrared radiation health care material is prepared by means of vacuum impregnation or veneer with the material with far?infrared ray emission performance. The preparation method is simple, efficient and practical.
This article summarizes the inherent health benefits of wood, summarizes the research advances in the above fields that are widely studied at this stage, and looks forward to the development prospects of health wood.
