Humectants for inhibiting flying dust of calcium carbonate and preparation method of humectants

Abstract

The invention discloses humectants for inhibiting flying dust of calcium carbonate. The humectants comprise a crusting dust suppressant, a water-soluble dust suppressant, a wetting agent, a film-forming agent, industrial paraffin, polyvinyl alcohol, acrylate, calcium magnesium acetate, triethanolamine and epoxy resin. The crusting dust suppressant is added in the preparation process of a first humectant, spraying is performed in a space with relatively high flying dust in a workshop, moisture in the air can be quickly combined, and the outer side of the dust is wrapped to form a film, so the quality of dust is improved, dust is settled to the ground; in the preparation process of a second humectant, the water-soluble dust suppressant is added, and after spraying, other types of dust in theair can be wrapped and dissolved and are finally settled to the ground; the crusting dust suppressant and the water-soluble dust suppressant are respectively added into a third humectant, dust in theair can be wrapped and form a film, and dust impurities are directly dissolved in the settling process; the humectant can be compatible with space moisture retention of most powder products includingcalcium carbonate powder production, and the production cost is effectively saved.

Description

technical field [0001] The invention relates to the technical field of moisturizing agents, in particular to a moisturizing agent for suppressing calcium carbonate dusting and a preparation method thereof. Background technique [0002] Humectants are often used in industrial production to keep the workshop environment or product raw materials and products moist, so as to prevent dust from contaminating product raw materials or finished products, thereby polluting product raw materials or finished products. Dust suppressants are often added to the moisturizer to suppress the occurrence of dust in the environment while maintaining humidity. A large amount of dust, the ecological high-efficiency dust suppressant is composed of a new multifunctional high molecular polymer, the cross-linked molecules in the polymer form a network structure, and there are various ion groups between the molecules.

[0002] Humectants are often used in industrial production to keep the workshop environment or product raw materials and products moist, so as to prevent dust from contaminating product raw materials or finished products, thereby polluting product raw materials or finished products. Dust suppressants are often added to the moisturizer to suppress the occurrence of dust in the environment while maintaining humidity. A large amount of dust, the ecological high-efficiency dust suppressant is composed of a new multifunctional high molecular polymer, the cross-linked molecules in the polymer form a network structure, and there are various ion groups between the molecules. There is a strong affinity between them, and through coagulation, bonding, etc., they can quickly capture and firmly absorb the particulate dust. After drying, they can solidify and form a film on the surface of the dust, so it has a strong dust suppression and dust prevention effect. , the humectants of the prior art only have a strong environmental humidity retention function, which can effectively improve the surface humidity of the space and products, but cannot quickly reduce a large amount of dust caused by air flow, especially in the calcium carbonate preparation workshop, the air The flow is very easy to cause calcium carbonate powder dust, resulting in a decrease in the output of calcium carbonate powder, resulting in an increase in production costs
