DETAILED DESCRIPTION - Environment-friendly decoration board comprises first Chinese medicine plate layer, anion adhesive layer, second traditional Chinese medicine plate layer and wax layer where anion adhesive layer is composed of soy protein adhesives and anion natural mineral powder at mass ratio of 6:4. The anion natural mineral powder is composed of tourmaline, lanthanide rare earth complex salt and titanium dioxide at weight ratio of 5:2:3. Tourmaline is made of magnesium tourmaline and lithium tourmaline at weight ratio of 4:6. The first and second traditional Chinese medicine plate layer is composed of 30-40 pts. wt. wood shavings, 3-4 pts. wt. Stellera chamaejasme, 3-4 pts. wt. bock greenbrier rhizome, 3-4 pts. wt. Rhododendron molle, 2-3 pts. wt. B vitamins tablets, 3-4 pts. wt. Rhamnus crenata, 3-4 pts. wt. Anemone hupehensis, 3-4 pts. wt. Gardenia, 3-4 pts. wt. camphor wood, 3-4 pts. wt. radix bupleuri, 3-4 pts. wt. fragrant, 3-4 pts. wt. lavender, 3-4 pts. wt. basil leaves, 3-4 pts. wt. vanilla, 0.3-0.5 pt. wt. radix paeoniae alba essential oil and 12-16 pts. wt. polyurethane adhesives. The environment-friendly decoration board is prepared by taking magnesium tourmaline, lithium tourmaline, lanthanide rare earth salts and complexes and titanium dioxide, placing into ultrafine grinding mill, milling to obtain anion natural mineral powder, mixing with soy protein adhesive, stirring for 15 minutes, standing, crushing traditional Chinese medicine raw materials into 130 mesh to obtain mixed powder, mixing radix paeoniae alba essential oil, mixed powder and polyurethane adhesives by high-speed dispersing machine for 20 minutes, standing, hot pressing at 100-110 degrees C for 30 minutes with pressure of 1 MPa/cm2 to obtain first and second traditional Chinese medicine plate, taking traditional Chinese medicine plate, coating with anion adhesive at an amount of 50-120 g/m2, covering with first layer of traditional Chinese medicine plate followed by second layer of traditional Chinese medicine plate, hot pressing at 85-130 degrees C for 1.5-5 minutes with pressure of 0.5-1.0 MPa/cm2, packaging, testing and storing.
