Abstract

The invention discloses a compound type chemical dust suppressant and a preparation method thereof. The compound type chemical dust suppressant disclosed by the invention comprises the following raw materials in percentage by weight: 5%-50% of polyethylene glycol 4000, 1%-20% of sodium sulfate, 2%-45% of polyvinyl acetate, 5%-55% of gelatin, 15%-70% of starch and 1%-10% of sodium polyacrylate. The compound type chemical dust suppressant disclosed by the invention has the advantages of high economic applicability, high practical applicability, environmental protection and good dust suppression effect. The raw materials for preparing the compound type chemical dust suppressant are low in cost, environment-friendly, non-poisonous and harmless to environments, and therefore, the compound type chemical dust suppressant has the effects of preventing dust pollution and protecting environments.

Description

technical field [0001] The invention relates to the technical field of dust suppressants, in particular to a composite chemical dust suppressant and a preparation method thereof. Background technique [0002] Dust can be divided into two categories according to particle size: large diameter is called dust fall, heavy weight is easy to settle, small diameter is called floating dust, it floats in the air in the form of aerosol for a long time, and people cannot see it with the naked eye. Dust contains a variety of heavy metals, and floating dust can absorb various toxic substances, some of which are carcinogens. The floating dust adsorbed with toxic substances is floating everywhere, seriously polluting the environment on which we live. [0003] The dust suppressant is composed of new multifunctional high molecular polymers. The degree of cross-linking between the polymer molecules will form a network structure, and there are various ionic groups in the molecules, which can ...
