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 dustproof biodegradable polymer emulsion of fixing the sand, that the macromolecule emulsion of preparing has is dustproof, preserve moisture, promote plant-growth, anti-erosion characteristic, is applicable to easy dusting place and mobile airborne dust situations such as soil, desert, industrial stockpile, dump, construction site.
Background technology
The particle diameter of airborne dust particulate matter is less, and it is the primary factor that causes the city particulate matter to pollute that its easy starting is flown upward.PM10 in the airborne dust, the particle of PM2.5 are less, and specific surface area is big, is vulnerable to various pollutions, a large amount of harmful elements of easier accumulation, and be detained in that atmosphere is medium-term and long-term, be detrimental to health.Stacking place of surface mining industry, the exposed face of land, city, some material of construction, desert etc. all are the main place that produces dust, are one of world's public hazards.Along with taking place frequently of pollution problems such as haze, affected area is more and more, has badly influenced people's orthobiosis 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 first comprehensive prevention and control of air pollution of China.Indicate that China's prevention and control of air pollution work progressively is controlled to be goal orientation to being that goal orientation changes to improve environmental quality by the total amount of pollutant, changed to not only preventing and treating primary pollution but also pay attention to secondary pollution by main control primary pollution.Current China dust-control method commonly used is watering and covering protection thing etc.But water resources is more precious now, and can only play effect for the moment; The coverage mode result of use is poor, can not solve reentrainment of dust.Therefore, the dedusting of research chemical mode is extremely urgent, dust suppression that can be permanently effective.At present, chemical dust-inhibitor is more and more studied and is used in China, but still has many incomplete places, is badly in need of developing cheap, easy to use, non-secondary pollution, the chemical dust-inhibitor that anti-dust effect is good.
Summary of the invention
The invention provides a kind of for dustproof biodegradable polymer emulsion and the preparation method who fixes the sand.
Material provided by the invention has easy handling, non-secondary pollution, can provide characteristics such as nutrition, degradation time is controlled to plant-growth.
The method that the present invention adopts is: at first aliphatic polycarbonate and/or aliphatic polyester are dissolved in the environmentally friendly solvent, add emulsifying agent again and prepare finish; In addition with polyvinyl alcohol and/or the modified starch aqua that makes soluble in water; Can add plant growth promoter as required.Will finish and aqua etc. join the emulsification of mulser high speed, and more than the stirring velocity 3000r/min, optimum revolution 5000-8000r/min makes the macromolecule emulsion that fixes the sand to have the complete biodegradable function for dustproof about 10 minutes.
After emulsion being sprayed at surfaces, airborne dust source such as exposed soil, the earthwork that excavates, coal piling field, ashery, emulsion can be infiltrated rapidly between the sand and dust grain crack, namely form one deck protective layer on the sandy soil surface after the curing, according to what of sprinkling amount, thickness probably can reach about 1-3 centimetre, can effectively separate air-flow to the direct effect of following loose sand and dust, bonding in blocks, thus play effect dustproof, that fix the sand.And in the growth place that plant is arranged, by adding plant growth promoter, make in the emulsion degradation process and can provide nutrition to plant, be conducive to plant-growth.
Embodiment
Embodiment
At first, the 100kg carbon dioxide copolymer is dissolved with poly-methylcarbonate, be mixed with 30% solution, add the 5kg sorbester p17 simultaneously and carry out emulsification.Then, get the 10kg polyvinyl alcohol again and be mixed with 30% the aqueous solution.Two kinds of solution are joined the reactor high speed stir, speed 5000 r/min took out after ten minutes.This emulsion is sprayed on the dump, and by observing, after fixing was finished in 30 minutes, formed the thick duricrust of 1cm, can effectively prevent travel fatigue.
