The invention relates to a quickly shaped diatomite composition with high strength and high function and a manufacturing method thereof. The composition comprises 100 portions of diatomite, 0 to 1,000 portions of stuffing, 50 to 300 portions of 
adhesive, 0 to 30 portions of 
antibacterial agent, and 0 to 30 portions of shaping and 
processing aid. Formulation and shaping 
manufacturing technology ofthe diatomite composition radically solve the problems that a common diatomite product has long producing and shaping period and low 
manufacturing efficiency; and the obtained product has the advantages of good 
mechanical property, light weight and low 
formaldehyde release, and has good functional properties such as 
flame retarding, water proofing, 
bacteria resistance and the like. The diatomite composition is applied to be manufactured into plates and profiles, can replace wood and artificial boards, and is used for products such as indoor and outdoor 
ornaments, office and household furniture, furniture components, 
acoustics, internal 
ornaments of vehicles, wall panels, security 
doors, wall boards, partition wall boards, packing materials, 
bed boards, floor, 
solid door frames, shutters, and the like.
