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
The present invention relates to a kind of for dust-proof biodegradable polymer emulsion of fixing the sand, the macromolecule emulsion prepared has dust-proof, moisturizing, Promoting plant growth, anti-erosion characteristic, is applicable to the easy dusting places such as soil, desert, industrial stockpile, dump, construction site and flowing airborne dust situation.
Background technology
The particle diameter of airborne dust particulate matter is less, and it is the primary factor causing city Particulate Pollution that its easy starting is flown upward.The particle of PM10, PM2.5 in airborne dust is less, and specific surface area is large, is vulnerable to various pollution, more easily accumulates a large amount of harmful element, and prolonged stay in an atmosphere, be detrimental to health.Stacking place, desert etc. of surface mining industry, exposed earth's surface, city, some material of construction are all the main place producing dust, are one of world's public hazards.Along with taking place frequently of the pollution problems such as haze, affected area gets more and more, and has badly influenced the orthobiosis of people and healthy.On September 27th, 2012, State Council has given an written reply " key area prevention and control of air pollution " 12 " planning ".This is the planning of China's first comprehensive prevention and control of air pollution.Indicate China's prevention and control of air pollution work progressively by contaminant transport model be goal orientation to environmental protect quality for goal orientation changes, change to not only preventing and treating primary pollution but also focus on secondary pollution by mainly preventing and treating primary pollution.The dust-control method that current China commonly uses is watering and covering protection thing etc.But water resources is more precious now, and can only plays and act on for the moment; Coverage mode result of use is poor, can not solve reentrainment of dust.Therefore, the dedusting of specializes in chemistry mode is extremely urgent, dust suppression that can be permanently effective.At present, chemical dust suppressant has obtained increasing investigation and application in China, but still has many incomplete places, is badly in need of developing cheap, easy to use, non-secondary pollution, the chemical dust suppressant that anti-dust effect is good.
Summary of the invention
The invention provides a kind of for dust-proof biodegradable polymer emulsion of fixing the sand and preparation method.
Material provided by the invention have easy handling, non-secondary pollution, can to the plant-growth feature such as provide nutrition, degradation time controlled.
The method that the present invention adopts is: first aliphatic polycarbonate and/or aliphatic polyester are dissolved in environmentally friendly solvent, then adds emulsifying agent and prepare finish; Another by polyvinyl alcohol and/or modified starch obtained aqua soluble in water; Plant growth promoter can be added as required.Will finish and aqua etc. join the emulsification of mulser high speed, more than stirring velocity 3000r/min, optimum revolution 5000-8000r/min, within about 10 minutes, obtain for the dust-proof macromolecule emulsion fixing the sand to have complete biodegradable function.
After emulsion being sprayed at exposed soil, the earthwork excavated, heap surface, the airborne dust source such as coal yard, ashery, emulsion can be infiltrated rapidly between sand and dust grain gap, namely one deck protective layer is formed on sandy soil surface after solidification, according to the number of fountain height, thickness probably can reach 1-3 cm, effectively can separate the direct effect of air-flow to loose sand and dust below, in flakes bonding, thus play effect that is dust-proof, that fix the sand.And in the growth place having plant, by adding plant growth promoter, making to provide nutrition to plant in emulsion degradation process, being conducive to plant-growth.
Embodiment
