Dust inhibitor and preparation method thereof

Abstract

The invention provides a dust inhibitor produced by tar residue, and a preparation method thereof, and belongs to the technical field of chemical materials. The dust inhibitor comprises the following components: 5% to 30% of polyacrylic resin, 0.5% to 2% of ethylene glycol, 20% to 30% of tar emulsion, 2% to 5% of SDBS, 0.5% to 1% of surfactant, 10% to 15% of hygroscopic matter, and reverse osmosis water. The preparation method comprises the following steps that: the tar residue is emulsified under the action of a demulsifier SDBS (ABS) and an emulsifier, and then the ethylene glycol, polyacrylic acid resin, the surfactant peregal and the hygroscopic matter calcium chloride are added to be evenly stirred to obtain the dust inhibitor. The invention has simple process and low cost, utilizes reverse osmosis concentrated wastewater, not only protects the environment, but also has good economic efficiency, and is a green circular economy project. The dust inhibitor provided by the invention has more than 90% of dust inhibition rate.

Description

Technical field [0001] The invention belongs to the technical field of chemical materials, and specifically relates to a dust inhibitor and a preparation method thereof. Background technique [0002] The iron and steel industry is an important basic industry of my country's national economy, and it is also one of the industrial sectors with serious energy consumption and environmental pollution. Environmental pollution is one of the important factors restricting steel production, especially dust pollution is particularly serious. Dust brings great harm to us, such as threatening people’s health and causing occupational respiratory diseases. Dust of 10um to 15um can cause chest tightness. Dust less than 10um can be inhaled into the lungs. Dust can also absorb a large amount of short-wave ultraviolet rays from the sun. Affecting the development of children, dust pollution can cause humans and animals to die from various diseases and even extinction, making the beautiful planet of ...

Problems solved by technology

Dust brings great harm to us, such as endangering people's health and causing occupational respiratory diseases. Dust of 10um to 15μm can cause chest tightness, dust less than 10μm can be inhaled into the lungs, and dust can also absorb a large amount of short-wave ultraviolet rays from the sun. Affecting the development of children, dust pollution can cause human beings and animals to die from various diseases and even become extinct, making the beautiful planet earth into a gloomy world like the moon; too fine dust can easily cause explosions and fires; Reduce environmental visibility; affect equipment life, etc.
