Construction site dust suppressant and preparation method thereof

Abstract

The invention discloses a construction site dust suppressant which is prepared from the following components in parts by weight: 66 parts of high-substituted hydroxyproxyl cellulose, 50 parts of lignocellulose, 20 parts of polylactic acid, 4 parts of zinc dialkyl dithiophosphate, 6 parts of starch aluminum octenylsuccinate, 1 part of sodium dodecyl sulfate, 8 parts of zinc stearate, 6 parts of propyl trimethoxy silane and 25 parts of deionized water. A preparation method of the construction site dust suppressant comprises the following steps: (1) preparing the high-substituted hydroxyproxyl cellulose, the lignocellulose and the polylactic acid into powder more than 200 meshes and stirring uniformly; (2) adding the zinc dialkyl dithiophosphate, the starch aluminum octenylsuccinate, the sodium dodecyl sulfate, the zinc stearate and the propyl trimethoxy silane into the deionized water, heating to 50-58 DEG C and stirring for 40-50 minutes under an ultrasonic condition; and (3) uniformly stirring the mixture in the step (1) with the mixture in the step (2) and carrying out vacuum drying at 20 DEG C to obtain the construction site dust suppressant.

Description

technical field [0001] The invention belongs to the technical field of ecological environment protection, and in particular relates to a construction site dust suppressant and a preparation method thereof. Background technique [0002] With the rapid development of the economy, the transformation of old cities and municipal construction are changing with each passing day. Building demolition and construction sites can be seen everywhere. The relatively obvious signs are the smoke and dust, and a large amount of dust blowing with the wind. It brings inconvenience to the life and work of the surrounding residents, and the construction unit often attracts "visit" and fines from the urban management and environmental protection departments. Conventional dust control measures for demolition of buildings are generally high-pressure water spraying (wasting a lot of municipal tap water), and the effect is not ideal; the earthwork on construction sites is exposed and piled up, and so...

AI Technical Summary

Problems solved by technology

Conventional dust control measures for building demolition are generally high-pressure water spraying (wasting a large amount of municipal tap water), and the effect is not ideal; the earthwork on construction sites is exposed and piled up, and some are covered with non-woven fabrics or sunshade nets, and dust still exists in windy weather , while most of the earthwork transportation did not take dust suppression measures, including the treatment of road surface dust in the loading and unloading links and transportation sections
