Abstract
The invention relates to wide area polymer colored modified emulsified asphalt and a processing method, and belongs to the technical field of petrochemical engineering. The asphalt is mainly prepared from the following components: 80 to 90 parts of matrix asphalt, 1 to 5 parts of nano-zinc oxide, 1 to 5 parts of nano-clay, 1 to 3 parts of diatomite, 1 to 3 parts of SBS, 3 to 5 parts of limestone, 3 to 5 parts of pigment and 1 to 2 parts of calcium stearate; the processing method of the asphalt comprises the steps of heating the matrix asphalt to 140 to 160 DEG C, adding the diatomite, SBS and limestone in proportions, continuously heating and stirring for 20 to 30min, then adding the nano-zinc oxide, nano-clay, pigment and calcium stearate, uniformly stirring at the temperature of 160 DEGC, and shearing for 30min; standing at room temperature for 6 to 8h, and then shearing for 20 to 30min to obtain the asphalt; the method is simple in process, energy-saving, environment-friendly, and low in cost; the asphalt prepared by adopting the method is excellent in performance and can be stably used under both high and low temperature conditions.
Description
Technical field
The present invention relates to a kind of modifying asphalt and working method, be specifically related to a kind of wide area polymkeric substance coloured modified emulsified asphalt and working method, belong to technical field of petrochemical industry.
Background technology
Along with the fast development that urban economy is built, main body in length and breadth, the network new road traffic general layout of scattereding all over like men on a chessboard day by day formed, diversiform vehicles number sharply increases, exacerbate the crowded of urban road on the one hand, officer travels on dullness like this, crowded road on the other hand, there will be eye strain unavoidably, finally lead to traffic accident.Improving constantly and strengthening the aesthetic standards of environment along with people's living standard, so people carry out laying of roadway by distinct colors, colored road surface just creates.It not only can relieve traffic congestion crowded, suppresses the traffic accident again and again occurred, to Dangerous Area to officer with warning, and skidproof effect is very good.It can allow the daily life of constraining of the mankind increase excellence, minds at rest, reduces pressure.
China started to inquire into color asphalt making technology the beginning of the eighties, and benefit is little, and in road engineering, application seldom.
Zhang Youfa in 2005 has analyzed and researched the production of chromatic bitumen mixture, construction temperature, and consumption is selected, water resistant stability, adhesion, high-temperature stability, every engineering property index such as weather resistance.By the contrast with modified asphalt mixture, show that chromatic bitumen mixture can not only meet the requirement of high-grade asphalt roads pavement usage, and the needs of Modernized City Construction development can be met, should vigorously promote the use.Liu in 2010 is first vast etc. discloses a kind of color asphalt ultrathin wearing layer and preparation method thereof, and it not only meets the requirement of colored road surface, and constructional method is simple, and easily, cost is also not high in maintenance.Recent years, color road is in bright 21 century also great Zhan radiance, and many amusement squares, urban road, middle heavy traffic Special zone etc. are making colored road surface all, and the benefit that colored road surface brings people is infinite.Relatively more extensive at present in China's colour asphalt pavement application, more than 20 province, the design whole nation, there are Beijing, Shanghai, Xiamen, Xi'an, Henan etc. in more typical city.
But Colourful pavement technology is also immature in China, up to the present also there is no complete standard specifications to evaluate its performance, so a lot of expert and scholar are studying it always.Whether can the color for color asphalt lasting, easily pollute, and whether maintenance is difficult; Next is that can pavement performance keep for a long time; Be it mix and stir again, whether construct with plain asphalt compound the same, have what special character.If big area making, cost value also can be very high.Color asphalt conventional in the market has a high-temperature behavior better, but the low temperature cracking resistance ability of powder color asphalt is lower, is not suitable for using in low temp area; Then being only suitable for of having uses under cryogenic, and use range is narrower.
Summary of the invention
The present invention is directed to prior art Problems existing, provide a kind of wide area polymkeric substance coloured modified emulsified asphalt and working method, technique is simple, environmental protection, and the performance of modified bitumen of preparation is stablized, and is widely used.
In order to solve the problem, the technical solution adopted in the present invention is:

A kind of wide area polymkeric substance coloured modified emulsified asphalt, is made up of the component of following weight part: matrix pitch 80 parts, nano zine oxide 2 parts, nanoclay 2 parts, 3 parts, diatomite, SBS2 part, 3 parts, Wingdale, pigment 3 parts, calcium stearate 1 part.
A working method for wide area polymkeric substance coloured modified emulsified asphalt, is characterized in that: comprise the steps:
Matrix pitch is heated to 140 ~ 160 DEG C, adds diatomite in proportion, SBS, Wingdale, continue heat and after stirring 20 ~ 30min, then add nano zine oxide, nanoclay, pigment and calcium stearate, stir under 160 DEG C of conditions, shearing 30min; Normal temperature shears 20 ~ 30min after leaving standstill 6 ~ 8h again.
The invention has the beneficial effects as follows:
(1) adopt multiple material compound, and select nano material and polymkeric substance, the material of different-grain diameter is complemented each other, and in pitch, dispersion effect is good, has given full play to network filling effect, and the viscosity of emulsified bitumen is increased, and performance is more stable.
(2) pitch adopting present method to prepare all can use under high and low temperature environment, and technique is simple, and energy-conserving and environment-protective, cost is low.
