Description
Technical Field
The invention relates to a method for quickly removing road snow by pre-coated anti-icing paint, belonging to the technical field of road snow removal.
Background
The common modes of road snow removal include manual snow removal, wind power snow removal, heating snow removal, snow melting agent snow removal, salt water jet snow removal, freezing pavement inhibiting technology and the like.
(1) And (5) manually removing snow. A large amount of manpower and material resources are consumed, the efficiency is low, and the personal casualties are easily caused. Manual snow removal is very inefficient and obviously not applicable to snow that is rolled by the vehicle many times, only through manual snow removal. (2) wind power snow removal. The automatic snow removing system for the turnout air pipeline has the advantages that the automatic snow removing system for the turnout air pipeline is suitable for turnout snow removing of various stations, and the problems that the working completion degree is low in a heavy snow day, the working capacity in a freezing rain weather is insufficient, the maintenance technology is difficult, and the help of electric power snow melting cannot be lacked when the air pipeline works exist in the current use process. The snow removing device has the advantages of high snow removing efficiency, high speed, stable and reliable work, low energy consumption, low cost, no damage to other peripheral equipment, environmental protection and the like. (3) heating and removing snow. The heating snow removing has the advantages of high snow removing efficiency and high safety, and the types of the heating snow removing device comprise electric heating snow melting, gas heating snow removing, steam heating snow removing and hot water heating snow removing. But they also have their own disadvantages. The electric heating snow melting electric power needs to be greatly increased in capacity, ice is easy to form when the heating time is insufficient, the heating strips are easy to fall off to influence the switch close contact, the later maintenance cost of replacing the heating strips is high, the operation cost is high, and the engineering investment is large. The gas heating snow removing engineering is complex and the investment is large. The steam heating snow removing needs to build a boiler or connect with municipal air source, the engineering is complex, and the investment is large. The hot water heating snow removing needs to build a boiler or connect municipal heat source, the engineering is complex, and the investment is large. (4) snow removing agent for removing snow. The automatic snow removing system for the air pipeline is applicable to road snow removing of various stations, and the problems that the working completion degree is low in a snowy day, the working capacity is insufficient in a rainy day, the maintenance technology is difficult, and the help of electric power snow melting cannot be lacked while the air pipeline works exist in the current use process. The snow removing device has the advantages of high snow removing efficiency, high speed, stable and reliable work, low energy consumption, low cost, no damage to other peripheral equipment, environmental protection and the like. (5) brine spray snow removal. The engineering investment of brine spraying snow removing is low, but the corrosion to the steel rail is easy to cause, the performance of a track circuit is affected, and the environmental protection is not facilitated. And (6) inhibiting freezing paving technology. The technology for inhibiting freezing pavement is characterized in that a certain amount of special materials are added into pavement materials to change the contact state of the pavement and tires and the deformation characteristic of the pavement, and the self-stress generated by the pavement under the action of external load is utilized to crush and melt ice and snow on the pavement, so that the aims of effectively inhibiting snow and ice on the pavement, namely the self-stress ice and snow removing technology, are fulfilled. The freezing-suppressing paving technology mainly comprises an elastic pavement paving technology, an inlaid paving technology, a rough paving technology and the like. The active deicing and snow-removing technologies generally have the problems of complex construction, difficult maintenance, strong use limitation, high cost and the like. Therefore, the research and development of the active snow removing method which is simple and convenient in construction, wide in application, low in cost, high in efficiency and low in energy is a key for solving the current ice and snow problem of the road surface.
Based on the existing road snow removing mode, the engineering investment is low and the snow removing effect is good on the premise of ensuring environmental protection, and the following main points are shown:
(1) The manual snow removal efficiency is low, and the manual snow removal is obviously inapplicable to snow which is compacted by rolling for a plurality of times;
(2) The existing use process of wind power snow removal also has the problems of low working completion degree in snowy days, insufficient working capacity in freezing rain weather, difficult maintenance technology, incapability of lacking assistance of electric power snow melting while working in wind pipelines, and the like;
(3) The snow melting agent is relatively simple in snow removing, good in snow removing effect and high in efficiency, but chemical components of the snow melting agent can severely corrode components made of cement concrete;
(4) The corrosion of the brine spray snow removing on the steel rail is strong, and the performance of a track circuit is influenced, so that the environmental protection is not facilitated;
(5) The freezing pavement inhibiting technology generally has the problems of complex construction, difficult maintenance, strong use limitation, high cost and the like.
Disclosure of Invention
The invention aims to develop an environment-friendly anti-icing paint which is free from corrosion to traffic facilities and pollution to the environment and provides a road snow rapid removal method which is coated with the anti-icing paint in advance aiming at the fact that the existing road snow removal mode is difficult to achieve unification of environment protection, economy and snow removal effects.
The invention adopts the technical scheme that the anti-icing paint for pre-coating comprises potassium acetate, sodium acetate, calcium acetate, emulsified asphalt, a water-based binding material and a chemical auxiliary agent; the optimal formula of the potassium acetate, the sodium acetate and the calcium acetate is 40 percent by mass percent and 20 percent by mass percent.
The best formula of the solid-state additive type snow-melting agent taking potassium acetate, sodium acetate and calcium acetate as main materials is adopted to obtain the self-made solid-state additive type snow-melting agent; mixing a certain amount of cationic emulsified asphalt, a water-based binding material and a chemical auxiliary agent, adding a self-made solid additive type snow-melting agent into the mixture, stirring the mixture uniformly, and then adding water to dilute the mixture to a specific concentration to obtain the anti-icing paint.
The cationic emulsified asphalt accounts for 40% -43%; water accounts for 35%; the stabilizer accounts for 1%; SBS modifier accounts for 1% -2%; the high-viscosity modifier accounts for 6% -8%; the self-made solid snow-melting agent accounts for 10-20 percent.

(3) Testing the index of the water seepage coefficient and the anti-slip coefficient of the construction road section;
(4) Determining the optimal spraying area, mechanically spraying the prepared anti-icing coating by adopting a spraying vehicle, and manually spraying the anti-icing coating to the local non-sprayed place;
(5) And closing the traffic for 8 hours and opening the traffic.
The invention analyzes the ice and snow melting mechanism of the snow melting agent to obtain that most of solid snow melting agents have deliquescence, and summarizes and generalizes chemical substances with low solution solidifying point and ice and snow melting capability by referring to a large number of documents; the basic principle of the ice and snow melting coating can discover that in order to achieve good use effect of the ice and snow melting coating, the coating must be ensured to have good bonding performance; the controlled slow release mechanism means that the preparation means is adopted to slowly and continuously release the medicine so as to achieve the aim of maintaining the stable blood concentration and reducing the frequency of taking medicine, and the thought can be used for improving the ice and snow melting coating.
The invention takes the freezing point as a parameter to screen out several substances with the lowest freezing point, and simultaneously considers the environmental protection of the self-made snow-melting agent to determine three chemical substances of potassium acetate, calcium magnesium acetate and calcium acetate which are relatively environmental protection and have low freezing point of the solution, and adopts a simplex gravity center design method to arrange the test, so as to solve and calculate the proportion corresponding to the maximum ice melting amount, namely the optimal proportion is potassium acetate: sodium acetate: calcium acetate = 40%:20%:40%. Mixing a certain amount of emulsified asphalt, a water-based binding material and a chemical auxiliary agent, adding a self-made solid additive type snow-melting agent into the mixture, uniformly stirring the mixture, and then adding water to dilute the mixture to a specific concentration to obtain the anti-icing paint. The anti-icing coating can be applied by using an artificial brushing or mechanical spraying mode, and the anti-icing coating can be obtained after the moisture evaporates and the coating is solidified.
According to the invention, the influence of ice and snow removing performance, durability and anti-skid performance of the anti-icing paint on the road surface is researched through experiments, and the following steps are obtained: the ice melting effect of the ice melting coating of the asphalt pavement coated with the anti-ice coating is obvious, the adhesion of the ice layer and the pavement can be permanently hindered, and the ice layer separated from the pavement is easy to break under the rolling of the running load, so that the aim of removing the ice and the snow on the pavement is fulfilled; the durability of the ice and snow melting coating of the asphalt pavement is tested, and the SBS modified emulsified asphalt coating is taken as a reference object. The test result shows that the ice and snow melting coating of the asphalt pavement has excellent wear resistance and adhesion with pavement aggregates; the influence of the ice and snow melting coating on the road surface on the friction coefficient and the construction depth of the road surface is tested, and the test result shows that the asphalt road surface coating has a certain influence on the road surface anti-skid property, but the influence degree is smaller, and the requirements of relevant design specifications, quality evaluation standards, construction technical specifications and the like are met.
In order to detect the environmental protection performance of the ice and snow melting coating of the asphalt pavement coated with the anti-icing coating, the invention designs a related test detection method to evaluate the injury effect of the ice and snow melting coating leaching liquid on plants and the corrosion effect of carbon steel, and the experimental analysis and evaluation on the plant injury and the steel bar corrosion prove that the ice and snow melting coating of the asphalt pavement completely meets the requirements of the environment and the road safety, and is a novel environmental protection road ice and snow removing method.

The comparison of the road surface water permeability coefficient and the friction coefficient in tables 1 and 2 shows that the anti-icing paint of the fifth embodiment has the best anti-seepage effect, the anti-skid performance is reduced compared with that of a blank road surface, but the anti-skid performance is not greatly different between the examples.
The deicing and snow effects of the fifth embodiment are explored, and the steps are as follows:
step one: a cylindrical asphalt mixture test piece with the thickness of 15 multiplied by 15cm is formed by adopting a rotary compaction method, then the test piece is cut into slices with the thickness of about 10 to 15 and mm by using a cutting machine, the slices are washed clean and then dried in a 60 ℃ oven, and the dried slices are cooled for standby;
step two: coating the surface of the slice test piece with a coating amount of 0.6 kg/m;
step three: and after the coating is dried, placing the slice test piece into quantitative water, and taking the blank test piece as a reference object. Then placing the test piece and water together in a low-temperature incubator at-15 ℃ to simulate the climate environment in winter;
step four: and taking out the slice test piece after 3 hours, freely falling the slice test piece at a position 50cm away from the test piece by using a weight of 500g, simulating the impact effect of an automobile tire on a road surface, and then observing the cracking condition of an ice layer and the bonding condition of ice cubes and a coating.
Test results show that the coating can effectively block the adhesion between the ice layer and the test piece at the temperature of-15 ℃ so as to separate the ice layer from the test piece and enable the ice layer to completely absorb impact force for breaking. Indicating that the coating has good deicing properties.
