▎ 摘  要

NOVELTY - Preparing durable diatom decorative wall material involves collecting 85-92 pts. wt. 25-50 mesh diatomaceous earth, then adding to powder modification machine and mixing with 8-15 pts. wt. powdered foaming agent to obtain mixture. The water-soluble emulsion containing graphene is sprayed on the surface of the mixture and dried to obtain surface-modified diatomaceous earth, where the thickness of the graphene-containing separator is 0.05-0.2 mu m. The surface modified diatomaceous earth is mixed with binder, dispersing agent, inorganic pigment, inorganic filler, and fiber toughening agent into a high-speed mixer, and stirring and mixing at a speed of 100-120 revolutions/minute for 20-40 minutes and discharging to obtain desired product. USE - Method for preparing durable diatom decorative wall material. ADVANTAGE - The method enables to prepare durable diatom decorative wall material, which effectively solves the hole blockage problem, improves the absorption effect, prevents the falling of graphene and cracking, improves the durability and prolongs the service life. DETAILED DESCRIPTION - The durable diatom decorative wall material comprises 46-63 pts. wt. surface modified diatomaceous earth, 1.5-3 pts. wt. binder, 0.5-1 pts. wt. dispersing agent, 18-25 pts. wt. inorganic pigment, 5-10 pts. wt. inorganic filler, and 12-15 pts. wt. fiber toughening agent.
