Description
Technical field
The present invention relates to urban construction articles for use field, and in particular to a kind of long-acting anti-freezing ice agent of coating type and its preparation side
Method.
Background technology
In recent years, as China's economy is developed rapidly, high-grade highway has also obtained fast development with urban road.Highway
Being becoming better and approaching perfection day by day to serve for Chinese society expanding economy of the network of communication lines greatly facilitates and guaranteeing role, but we should also see
To the restriction problem occurred during highway construction, wherein most importantly winter highway pavement accumulated snow phenomenon.With regard to current
From the point of view of situation, the winter deicing method generally used both at home and abroad has：Manually except snow dust, spreading Snow Agent method and mechanical deicing's snow
Method etc., is sometimes carried out three also according to concrete condition appropriately combined.The Snow Agent being widely used is chloride salt Snow Agent, this
Class material advantages are that valency is low, easy to operate, deicing effect is obvious；Have the disadvantage have seriously to the infrastructure of road and its surrounding
Corrosivity, welding, it is impossible to meet the sustainable development requirement of communications and transportation.
Anti-freezing point bituminous paving can reduce the freezing point of pavement surface water by the lasting precipitation of salinity, and continue to melt
Road surface accumulated snow.Compared with traditional Snow Agent, the fountain height and sprinkling number of times of Snow Agent on the one hand can be reduced, so as to reduce
The environmental pollution that villaumite is caused to the corrosion failure of works on the way and to air, soil and crops etc..On the other hand, salinization
Thing snow-melting asphalt pavement can make to form loose contact between accumulated snow and road surface, so as to reduce snow removal with machine difficulty, improve and make
Industry efficiency, reduces the maintenance cost of winter road.
Anti-freezing ice agent is also known as anti-freezing point asphalt pavement admixture, is directly incorporated into asphalt with suppression jelly
A kind of additive of effect is tied, is added in asphalt, under vehicular load, salinity in additive is from compound
Capillary gap in gradually separate out, so as to reduce the freezing point of road surface water, it effectively suppresses the composition predominantly salinization freezed
Thing, common sodium chloride, calcium chloride etc..
For the research of anti-freezing point asphalt pavement technique, China is still in the stage of desk study, the big portion done at present
Point research work mainly or concentrate abroad from snow melt road surface additive.Chongqing Jiaotong University's Cui Long tin is external to addition
Product V-260 storage salt road surface is studied, the main storage salt road surface mix composing design method for including admixture V-260, work
With mechanism and pavement performance evaluation.The Zhang Lijuan research incorporation additive external product Mafilon's of Chang An University drips from snow melt
The pavement performance and workability on blue or green road surface, by controlling salt incorporation, make salt from the road of snow melt asphalt
Code requirement is disclosure satisfy that with performance.Chongqing Jiaotong University Kang Jie is studied homemade salt storage aggregate, it was demonstrated that to zeolite
The effect of road surface deicing snow can be played instead of gathering materials in asphalt by carrying out gathering materials after salinization processing, and he is by this kind afterwards
Material application proposes anti-freezing ice micro-surface area, and its deicing performance is verified into the processing of road surface micro-surface area, it was demonstrated that should
Salt storage aggregate has certain anti-freezing ice effect, but long-term effect requires study and strengthened.In terms of ice-melt snow effect long-term effect, day
This support Practical Project has carried out the measure of long-term effect, and proves after 5-6, and storing salt road surface still has certain deicing work(
Can, domestic Chang An University Sun Yu is neat to there is some researchs in terms of deicing long-term effect, but research is only limitted to the leaching under hydrostatic condition
Bubble method, it is impossible to rational simulated roadway actual conditions.
High polymer material film-coating technique is applied to agricultural and medicine and other fields, such as drug coating and fertilizer and pesticide bag always
Film, carries out coating to salt applied to the agent of anti-freezing ice and has no report.
Macrogranule salt is that the salt solution in seawater or salt well, salt pond, brine spring is through decocting the crystallization shone, its main component
NaCl, possesses melting ice and snow effect., not only can be with by the use of macrogranule salt as the Snow Agent of long-acting anti-freezing ice asphalt pavement admixture
Reduction prepares cost and develops this huge resource, and after coating is handled, salt ion is slowly released, and is made
Snow Agent has long-term effect, and this development to national economy is undoubtedly significant.
The content of the invention
In view of the above-mentioned problems, both there is good solidifying ice Thaw performance the invention provides a kind of, there is long-term effect again
