Dustproof sand stabilizing biodegradable high-molecular emulsion and preparation method thereof

Abstract

The invention relates to a dustproof sand stabilizing biodegradable high-molecular emulsion and a preparation method thereof. The prepared high-molecular emulsion has the characteristics of being dustproof, preserving moisture, promoting growth of plants and preventing water and soil loss, and is suitable for places where dust is easy to be generated, such as soil, desert, industrial material stacks, coal stacks and construction sites. After being sprayed on the surface of a dust flying source, the emulsion can quickly permeate into the clearances of sand particles and then cured to form a protective layer on the surface of the sand, so that a direct effect generated by the air flow can effectively isolated from the loose sand there-below, and the emulsion is adhered as pieces so as to achieve effects of preventing dust and stabilizing sand. Moreover, in growing place of plants, by adding a plant growth promoting agent, the degradation of the emulsion can provide nutrition for the plants and contributes to growth of the plants.

Description

technical field [0001] The invention relates to a biodegradable polymer emulsion used for dust prevention and sand fixation. The prepared polymer emulsion has the characteristics of dust prevention, moisture retention, plant growth promotion and soil loss prevention, and is suitable for soil, desert, industrial stockpile, coal Dust-prone places such as piles and construction sites, as well as the flow of dust. Background technique [0002] The particle size of dust particles is small, and its easy to start flying is the primary factor causing urban particle pollution. The particles of PM10 and PM2.5 in the dust are small and have a large specific surface area, so they are susceptible to various pollutions, accumulate a large amount of harmful elements more easily, and stay in the atmosphere for a long time, endangering human health. Open-pit mining, urban bare ground, some building material storage places, deserts, etc. are the main places that generate dust, which is one o...
