NOVELTY - Environmentally-friendly diatom mud wall material comprises 50-75 pts. wt. diatomaceous earth, 10-13 pts. wt. nano-titanium dioxide, 10-12 pts. wt. heavy calcium, 5- 9 pts. wt. wollastonite powder, 5-8 pts. wt. quartz powder, 4-8 pts. wt. attapulgite powder, 4-8 pts. wt. ash calcium powder, 4-6 pts. wt. graphene, 3-7 pts. wt. propyl gallate, 2-7 pts. wt. anion powder, 2-15 pts. wt. dispersant, 5-9 pts. wt. surface modifier, 5-10 pts. wt. anti-mold antibacterial agent, 2-7 pts. wt. water resistant agent and 5-8 pts. wt. binder; where, the surface modifier is prepared by mixing sodium dodecyl sulfate, sodium hexadecyl glycinate and stearic acid; the anti-mold antibacterial agent is prepared by washing Aloe vera, cloves, giant tail scorpion and vanilla, smashing to obtain Chinese medicine powder, adding deionized water, boiling to obtain the Chinese medicine solution, cooling, placing in 60-75% ethanol, sterilizing and concentrating. USE - Used as environmentally-friendly diatom mud wall material. ADVANTAGE - The method is simple. The diatom mud wall material has better anti-mildew and antibacterial property, superior strength, flexibility and crack resistance, does not fall off easily, and is resistant to dirt. DETAILED DESCRIPTION - Environmentally-friendly diatom mud wall material comprises 50-75 pts. wt. diatomaceous earth, 10-13 pts. wt. nano-titanium dioxide, 10-12 pts. wt. heavy calcium, 5- 9 pts. wt. wollastonite powder, 5-8 pts. wt. quartz powder, 4-8 pts. wt. attapulgite powder, 4-8 pts. wt. ash calcium powder, 4-6 pts. wt. graphene, 3-7 pts. wt. propyl gallate, 2-7 pts. wt. anion powder, 2-15 pts. wt. dispersant, 5-9 pts. wt. surface modifier, 5-10 pts. wt. anti-mold antibacterial agent, 2-7 pts. wt. water resistant agent and 5-8 pts. wt. binder; where, the surface modifier is prepared by mixing sodium dodecyl sulfate, sodium hexadecyl glycinate and stearic acid in the mass ratio of 2:2:1; the anti-mold antibacterial agent is prepared by washing 40-50 pts. wt. Aloe vera, 20-35 pts. wt. cloves, 15-25 pts. wt. giant tail scorpion and 5-15 pts. wt. vanilla, smashing, pass via 100-120 mesh sieve to obtain Chinese medicine powder, adding 15-18 times of deionized water, boiling for 30-40 minutes to obtain the Chinese medicine solution, cooling to 30-35 degrees C, placing in 60-75% ethanol in an ultrasonic environment of 50-52 kHz for 10-15 hours, sterilizing by filtering and concentrating in a vacuum to a concentration of 500-600 mg/ml. The water resistant agent is an inorganic aluminum salt or a urea resin; the binder is prepared by mixing VAE emulsion, gypsum powder, polyvinyl alcohol and gelatin in a weight ratio of 3:2:2:1. An INDEPENDENT CLAIM is also included for preparing an environmentally-friendly diatom mud wall material, comprising: (i) placing the diatomaceous earth in a fast ball mill for 10-15 minutes, passing through a 300-400 mesh sieve, and adding the diatomaceous earth into a pulverization chamber of a screw feeder, and introducing high-pressure gas of 60-70 degrees C into the pulverization chamber, crushing to 3000-3200 meshes, adding dispersing agent and surface modifier, mixing and stirring uniformly, then mixing and stirring at 105-135 degrees C for 30-45 minutes, and drying to obtain surface modified diatomaceous earth; (ii) mixing the surface-modified diatomaceous earth with the anion powder, adding nano titanium dioxide, heavy calcium, wollastonite powder, quartz powder, attapulgite powder, ash calcium powder, graphene and propyl gallate, stirring at 300-400 revolutions per minute for 20-30 minutes, adding the anti-mold antibacterial agent, continung stirring for 20-35 minutes in an ultrasonic environment of 40-45 kHz, and uniformly dispersing the mixed seasoning in micropores of the diatomaceous earth, to obtain mixture of diatomaceous earth; (iii) adding the diatomaceous earth mixture into a high-speed mixer, adding a water-resistant agent and a binder, stirring and mixing at 600-900 revolutions per minute for 20-50 minutes, and discharging the product to obtain the product.
