Abstract

The invention discloses a multifunctional and environmental protective hard board composed of fibre or paring, and a preparation method thereof. In the production process of the hard board, appropriate quantity of functional material is mixed in the plant fibre or in the paring; the functional material contains tourmaline powders; wherein, proportioning by weight of the plant fibre or the plant paring and the tourmaline powder is 100:0.5 to 10; thereby the prepared hard board has manifold environmental protective functions such as anion releasing, far infrared ray emission, antibiosis, room air purifying, degradation of noxious gas (like formaldehyde, toluene nitrogen oxide, etc.), etc.

Description

technical field [0001] The invention relates to an artificial board, in particular to an artificial board made of fibers or shavings and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, the awareness of environment and health is gradually increasing, and people will pay more and more attention to green materials and environmentally friendly products. Health, longevity and comfort have become the highest goals pursued by people. Environmental protection, health and antibacterial products came into being and developed rapidly. Wood-based panels are closely related to people's daily life as building materials such as home furnishing and decoration, so people have put forward higher requirements for the health and environmental protection functions of wood-based panels. [0003] In CN1974638 literature, a kind of environment-friendly composite floor is disclosed, comprising a wear-resistant layer, a high-...
