Abstract

The invention relates to a traditional Chinese medicine dreg composite material panel capable of slowly releasing traditional Chinese medicine flavor and a preparation method of the panel. The panel comprises a porous anti-aging surface layer, a slow-release middle layer and a mildew-proof bottom layer, wherein the slow-release middle layer is located between the porous anti-aging surface layer and the mildew-proof bottom layer; the porous anti-aging surface layer is prepared by the steps of mixing polyolefin plastic, a traditional Chinese medicine dreg, a foaming agent, an antioxidant, talcumpowder and chlorinated polyethylene, and carrying out extrusion and calendering; the slow-release middle layer is prepared by the steps of mixing polylactic acid, the polyolefin plastic, a flavoringagent, a plasticizer, acrylic acid grafted starch and the traditional Chinese medicine dreg, and carrying out extrusion and calendering; and the mildew-proof bottom layer is prepared by the steps of mixing the polyolefin plastic, the traditional Chinese medicine dreg, standard sand, a mildew-proof antibacterial agent and maleic anhydride, and carrying out extrusion and calendering. The panel is convenient to manufacture, low in cost, high in modulus and capable of resisting creep deformation, and the waste utilization of the traditional Chinese medicine dreg can be realized; and meanwhile, thepanel is capable of releasing a light and non-toxic natural fragrance and providing an environment-friendly and healthy living condition to customers and can be applied to the occasions of luxuriousoffice buildings and halls, house working and the like.

Description

technical field [0001] The invention discloses a composite material board, in particular to a composite material board made of traditional Chinese medicine dregs which releases the fragrance of traditional Chinese medicine slowly and a production method thereof. Background technique [0002] In recent years, the research and application of wood-plastic composite materials have received high attention. It has excellent anti-corrosion, waterproof, crack-proof and anti-fouling properties, no secondary processing, easy installation, no toxic chemical components, low-carbon environmental protection, It does not need to be painted, polished, easy to maintain, easier to clean, heat and sound insulation, etc., so it can be widely used in various occasions such as indoor and outdoor decoration, garden engineering construction, workshop anti-corrosion engineering, marine anti-corrosion engineering, sanitation facilities, etc. It can be used as pallets, Packaging materials such as pack...
