Abstract
The invention belongs to the field of dust suppressant, and in particular relates to a novel environment-friendly road surface dust suppressant of which the raw materials consist of 4-6 parts of base oil, 93.5-95.5 parts of water and 0.1-1.0 part of surfactant by weight. The raw materials of the dust suppressant have the organic cooperation and synergistic effect, so that a road surface is kept wet and dust can be adhered, the effective dust suppression time is long, that is, more than 15 days, and the dust suppression efficiency is more than 80%; along with the increase of the times that the dust suppressant is sprayed on the road surface, the dust and grits thrown from vehicles on the road surface can be adhered together to be formed into stable soil, and a layer of oil film is formed on the road surface, so that the function or maintaining and protecting a road is achieved; the application range is wide, that is, except for being used for suppressing dust on roads of strip mines, the dust suppressant can also be widely applied to dust suppression in fields such as urban road construction, refuse dump, tailings warehouses, bulk material fields and the like; and the raw materials are wide in resource, the price is low, the preparation method is simple, convenient and easy to carry out, and therefore, the dust suppressant is applicable to large-scale popularization and application.
Description
Technical field
The invention belongs to the dust-inhibitor field, be specifically related to contain in a kind of raw material the novel environment friendly road surface dust-inhibitor of base oil, water, tensio-active agent.
Background technology
Highway is the Aorta of Production of Strip Mine, and the environmental evaluation of relevant surface mines air quality is consistent both at home and abroad thinks, during the rock of automobile transportation ore deposit, road surface driving airborne dust often is the dust pollution source of full ore deposit maximum, and it causes the main root of surface mines topsoil especially.
The surface mines highway is generally native stone or the provisional road of rubble, and the build standard of road is on the low side, and construction quality is relatively poor, and routine maintenance is not enough.When automobilism, dust fills the air, and the dustiness in every cubic metres of air causes serious dust pollution up to hundreds of milligrams.The road surface airborne dust not only can be detrimental to health and destroy physical environment, makes plant withered, and can influence driver's sight line, reduces the road speed of truck and the distance of two trucies that travel of increase, increases haulage time, reduces conveying efficiency; Simultaneously, behind the air of the high dustiness of the long-time suction of truck cylinder, the cylinder wear aggravation, oil consumption increases greatly, thereby directly affects engine overhaul time limit and the transportation cost of automobile; In addition, because open-air tunnel road dust prevention does not catch up with, rock particle in ore deposit scatters on the way in addition, and road conditions go from bad to worse, and auto tire wear is serious, and the vehicle maintenance expense more can improve greatly.
Traditional road surface dust-control method is with water barrow watering, i.e. wet dust removal method, but water evaporates and infiltration are very fast on the high temperature dry soil property road surface in summer, to such an extent as to can not be effectively dustproof.And transport routes scene in ore deposit is difficult to accomplish the operation of frequently sprinkling water in the open, and the operation meeting of frequently sprinkling water makes low class pavement be subjected to more havoc, thereby increases the wearing and tearing of doughnut and shorten the life of a car.Another kind of road surface dust-control method is directly to lay high-grade cement or bituminous pavement, but owing to can scatter a large amount of rubble earth inevitably in the rock process of truck haulage ore deposit, the road surface airborne dust still exists; Moreover, economical and technical do not allow to cheat in the open in the laying high-grade highway.Therefore, need develop a kind of dust suppression efficient height, effectively long road surface dust-inhibitor of dust suppression time.
Summary of the invention
The object of the present invention is to provide the novel environment friendly road surface dust-inhibitor that contains base oil, water, tensio-active agent in a kind of raw material.
The objective of the invention is to be achieved through the following technical solutions:
A kind of novel environment friendly road surface dust-inhibitor, the raw material of described dust-inhibitor comprises base oil, water, tensio-active agent, more than each raw materials in part by weight ratio be: base oil 4-6, water 93.5-95.5, tensio-active agent 0.1-1.0.
Further, described base oil is residual oil; Described residual oil is one or more in cinder oil, wooden residual oil, shale residual oil, light oil, heavy oil, soft resin, fluxed bitumen, mediation residual oil, the coal tar.
Further, described water is natural water, one or more in the tap water.
Further, described tensio-active agent is one or more in hexadecanol, lauryl alcohol, sodium lauryl sulphate, fatty alcohol-polyoxyethylene ether (5-12), rosin, sulfonate, alkylol amide, aliphatic alcohol polyethenoxy ester (5-12), the smart resin acid.
The objective of the invention is to be achieved through the following technical solutions:
The preparation method of a kind of novel environment friendly road surface dust-inhibitor, the raw material of described dust-inhibitor comprises base oil, water, tensio-active agent, more than each raw materials in part by weight ratio be: base oil 4-6, water 93.5-95.5, tensio-active agent 0.1-1.0;
This preparation method may further comprise the steps:
A, described base oil is carried out thermal pretreatment, reach softening temperature, add a kind of described tensio-active agent again and mix, obtain mixture A;
B, heat described water, reach and be higher than 80 ℃, add another kind of described tensio-active agent again and mix, obtain mixture B;
C, described mixture A and mixture B are mixed, obtain described mixture C;
D, from described mixture C sample thief, other gets clear water with this diluted sample 30-80 doubly, fully shakes up the formation emulsion, namely obtains described dust-inhibitor.
Dust-inhibitor of the present invention is a kind of oil in water emulsion liquid that can be water-soluble, and surface tension is lower than water, is easy to adhere to dust; Spray the road surface, back and form one deck oil film, can stop the evaporation of bottom moisture content, and the ground dust that can bond, particularly after repeatedly spraying, the glued situation in road surface is constantly improved, if long-term the sprinkling, anti-dust effect will be more and more better, and macadam pavement will form the road surface of class sapropelitic gradually.Therefore, spilling liquid will constantly prolong pitch time; The both sides of highway that is rolled by wheel tyre can not adhere to dust fall because one deck oil film is arranged, and when blowing, dust can not kicked up, and can cling the dust that automobile is kicked up, thereby suppresses the diffusion of flying upward of dust.
The present invention has following beneficial effect compared to existing technology:
1, the organic cooperation of each raw material, synergy among the present invention can keep the road surface wetting, the bonding dust, and effective dust suppression time is long, can reach more than 15 days, and dust suppression efficient is more than 80%;
2, dust-inhibitor of the present invention is along with the increase of spraying number of times on the road surface, can make the dust on road surface and particle that automobile scatters be bonded to Stabilized Soil, and form one deck oil film on the road surface, plays the effect of maintain road road maintenance;
3, use range of the present invention is extensive, except being used for the dust suppression of surface mines highway, also can be widely used in the dustproof of various places such as urban road construction, refuse dump, tailings storehouse, bulk material field.
4, technical feature of the present invention is good, and the every technical indicator of product is: viscosity 5-20mPa.s, and the pH value: 6 ~ 8, surface tension: 30-60mN.m
-1, water retention: 10 ~ 30%, anti-dust effect 〉=80%.
5, the wide material sources of each raw material of the present invention, cheap, the preparation method is simple and easy to do, is suitable for large-scale promotion and uses.
