The invention discloses a method for improving the colloid stability of attapulgite clay. According to the invention, a principle that moisture is converted into gas from solid ice under a vacuum condition is adopted to dehydrate and dry materials, the specific surface area of the attapulgite clay is increased, the agglomeration of attapulgite clay rod crystals is reduced, and thus the colloid stability of the attapulgite clay is increased.

The invention provides a sludge solidifying agent prepared by using slag, a preparation method and application thereof. The curing agent is prepared from the following raw materials in mass percentage: 15-25% slag, 20-25% modified diatomite, 20-25% attapulgite, 10-15% silica fume, 4-8% Powdered activated carbon, 5-10% peroxide, 1-3% potassium permanganate, 1-2.5% iron powder, 1-5% cationic chelate, 1-5% polyrotaxane, 1-5% polyacrylic acid Sodium, 0.1-0.8% alkaline activator, 0.1-0.5% water reducer, 0.1-0.3% thickener, fully mix the above raw materials in a mixer, and mix them according to the mass ratio of 5%-30% of the sludge Put it into the mud, then mix it thoroughly, let it dry and cure naturally for 0.5‑1h before use. The invention has the advantages of simple curing process, short curing time and high efficiency. During the curing process, the toxic and harmful substances in the sludge can be degraded, and the peculiar smell in the sludge can be removed. The cured sludge will not cause secondary pollution.

The invention discloses a nano flame-resistant concrete protective coating and a preparation method thereof, wherein the protective coating comprises the following ingredients in parts by weight: 55-75 parts of modified nano-silica sol emulsion, 8-10 parts of attapulgite whiskers, Schiff base modified 3-5 parts of non-toxic graphene compound, 0.2-0.5 parts of wetting and dispersing agent, 0.2-0.5 parts of thickener, 0.2-0.5 parts of defoamer, 1-3 parts of leveling agent, 25-35 parts of deionized water . The preparation process is as follows: mix the modified nano-silica sol emulsion, attapulgite whiskers, and Schiff base modified graphene compound according to the above protective coating formula, and use a high-speed disperser to stir and disperse at high speed for 30-60min; then the above protective coating Add the remaining wetting and dispersing agent, thickener, defoamer, leveling agent, and deionized water to the formula; adjust the state of the high-speed disperser to medium-speed stirring and dispersing, continue stirring evenly, and then filter and pack. The protective coating provided by the invention has good physical and chemical properties such as alkali resistance, water resistance, weather resistance, adhesion, fire resistance and the like.

The invention discloses an environment-friendly type seed coating film-forming agent and a preparation method thereof. The film-forming agent consists of 0.1-1.8% of attapulgite, 0.005-0.01% of film-forming accessory ingredient, 0.5-6% of emulsifying wetting suspending agent, 0.6-4% of penetrating agent, 0.02-0.08% of preservative, 2.0-6.0% of freeze proof agent, 0.05-0.6% of viscosity stabilizing agent, 0.1-0.7% of warning color and 80.81-96.625% of water. The preparation method comprises the steps of: adding the attapulgite into the water with the quality volume ratio of 1:20; adding the emulsifying wetting suspending agent to obtain attapulgite suspension liquid; adding the film-forming accessory ingredient into boiling water with the quality volume ratio of 1 / 500 to obtain cleaning liquid; adding the penetrating agent, the preservative, the freeze proof agent and the viscosity stabilizing agent into the cleaning liquid to obtain mixture; adding the attapulgite suspension liquid into the mixture, and adjusting the pH value to be 6.2-7.2; and adding the warning color and compensating the water to be total weight, and grinding to obtain the film-forming agent. The film-forming agent is environment-friendly, can adjust the loading quantity, can adjust the growth microenvironment of seeds, and has stable performance and low price.
