Abstract

The invention discloses a tea biomass composite material and a preparation method and application thereof. The tea biomass composite material is prepared from the following raw materials in parts by weight: 60 to 70 parts of tea biomass, 20 to 50 parts of wood meal, 12 to 30 parts of straw powder, 2 to 5 parts of compatilizer, 0.2 to 1.5 parts of lubricant, 2 to 3 parts of coloring agent, 0.1 to 3 parts of antioxidant and 0.1 to 3 parts of stabilizer. The preparation method comprises the following steps of weighing the raw materials according to requirements; soaking the tea biomass for 20 to 48h at the temperature of 60 to 80 DEG C, cleaning, airing, and crushing to 10 to 20 meshes for further use; mixing the tea biomass treated in step 2 and the wood meal, the straw powder, the compatilizer, the lubricant, the coloring agent, the antioxidant and the stabilizer, uniformly stirring, and feeding into a granulating machine for granulating at the temperature of 60 to 118 DEG C, so as to obtain a master batch; feeding the master batch into an extruding machine, and extruding, so as to obtain the tea biomass composite material. The tea biomass composite material has the advantages that the mechanical property is good, the sterilizing and bacteria-inhibiting ability is strong, the moisture absorbing ability is realized, and the tea biomass composite material is suitable for serving as an outdoor floor and furniture material.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a tea biomass composite material and its preparation method and application. Background technique [0002] my country is a large agricultural country, and the annual output of tea biomass is large, but the current method of processing tea biomass is mostly incineration, which not only pollutes the air, but also wastes resources, especially in today's society, where smog is everywhere, so it is necessary to develop a green processing method. [0003] Tea biomass contains caffeine, tannins, tea polyphenols, proteins, carbohydrates, free amino acids, chlorophyll, carotene, aromatic oils, enzymes, provitamin A, vitamin B, vitamin C, vitamin E, vitamin P and inorganic salts , trace elements and more than 400 kinds of ingredients. Like other crop straws, tea biomass contains a lot of fiber, and tea biomass has unique moisture absorption and antibacterial and bactericidal cap...
