1. A method for preparing a tea-based composite board, comprising steps of:
Step 1: weighing raw material components in the following proportions: 60-70 parts of waste tea residues, 20-50 parts of tea stems, 12-30 parts of straw powder, 10-30 parts of tea pectin cellulose, 30-40 parts of coffee residues, 2-5 parts of a compatibilizer, 0.2-1.5 parts of a lubricant, 2-3 parts of a colorant, 0.1-3 parts of an antioxidant, and 0.1-3 parts of a stabilizer;
Step 2: soaking the tea stems in water at 60-80° C., performing through cleaning, drying in the air, and grinding to obtain tea powder with a mesh size of 10-20 meshes;
Step 3: mixing the waste tea residues, the tea powder, the straw powder, the tea pectin cellulose, the coffee residues, the compatibilizer, and the lubricant at 120-150° C. for 20-30 min;
Step 4: lowering the temperature to 50-60° C., further adding the colorant, the antioxidant and the stabilizer, performing uniform mixing, and performing hydro-molding at 50-118° C. to obtain the tea-based composite board.
