Description
Technical Field
The invention relates to the technical field of new materials, in particular to a colorful anti-freezing coating.
Background

Detailed Description

The preparation process of the colored anti-freezing ice coating comprises the following steps of proportioning the components in parts by weight.
Preparation of hydrophobic component
Step one, 4 parts of reinforcing agent (carbon black), 3 parts of filler (titanium dioxide, zinc oxide powder and barium sulfate are in a ratio of 1:1:1) and 4 parts of film forming additive 2,2, 4-trimethyl-1, 3-pentanediol monoisobutyrate are added into 180 parts of diluent water, and the mixture is stirred for 20min at the rotating speed of 300 rpm;

II) preparation of the adhesive component
1 part of silicon rubber cross-linking agent, 1.5 parts of silane coupling agent, 20 parts of emulsified asphalt, 40 parts of rubber powder and 40 parts of epoxy resin are mixed and stirred uniformly to obtain the adhesive component.
Thirdly) preparation of the freezing point depressing component
And 3 parts of sodium chloride and 6 parts of calcium chloride are mixed to obtain the freezing point depression component.
Four) preparation of the coating
And mixing and stirring 15 parts of adhesive component, 8 parts of hydrophobic component and 2 parts of freezing point depression component with 3 parts of pigment component at normal temperature until a uniform colored anti-freezing ice coating is obtained.
The soil layer of the application can be sprayed by using related spraying equipment or manually at a speed of 0.4-0.6 kg/m2The amount of (2) is used for construction.
In order to verify the effect, the anti-freezing coating is uniformly coated on a glass slide according to 0.3kg/m2, the surface of the glass slide is washed clean by clear water, and after the glass slide is dried, a contact angle detector is used for measuring the contact angle of the glass slide.
According to the testing procedure of drop image analysis method, a photograph is taken of the surface of a glass slide which is not coated with an organic hydrophobic coating and the surface of a glass slide which is coated with an organic hydrophobic coating, and the static contact angle is compared, as shown in figure 1, the left side is a drop on a common glass slide (control group), and the right side is a drop on a glass slide (coating group) coated with the coating of the application
From the image data and measured by the contact angle measuring instrument, the contact angle of the droplet on the coated slide was 95 °, while the contact angle of the droplet on the clean slide was 32 °. The data comparison can show that the coating has good hydrophobic performance and can obviously reduce the adhesive force between the ice layer and the pavement.
And the wettability test is also carried out, the effect is shown in fig. 2, wherein the left side is a common road surface, the right side is a road surface sprayed with a coating, and the photographed picture shows that when water drops are dripped on a coating test piece sprayed with the paint, the water drops have obvious shrinkage gathering phenomenon, and on the test piece not sprayed with the coating, the water drops have no obvious shrinkage gathering phenomenon and are continuously diffused. Before the common asphalt pavement is frozen, ice water penetrates into the asphalt pavement, ice whiskers are formed in pores of an asphalt pavement structure and are tightly nailed to the pavement, and an ice layer is uniformly and continuously covered on the whole pavement; and the hydrophobic road surface that the spraying has the coating of this application can obvious shrink because of the water droplet and gather together the phenomenon, and the ice sheet that forms is discontinuous state and distributes in local area.

From the test results above, it is seen that the adhesion decreased 31.45% for the coated and uncoated coatings. The coating obviously reduces the adhesion between the ice layer and the asphalt pavement, and the low adhesion is beneficial to crushing the ice layer by the tire, so that the ice layer is easier to strip and clean.

The process of detection by the weighing mechanism 8 is as follows: after a certain amount of the slowly-releasing shells are contained in the containing barrel 701 (the weight is known, for example, the total number of turns of the first worm 505 is known), the first electric push rod 702 is started to cause the output shaft of the first electric push rod 702 to slide the containing barrel 701 downwards, so that the containing barrel 701 (with fine meshes) moves to the inside of the soaking barrel 3, at this time, the dispersion liquid in the soaking barrel 3 carries the previously added compound salt into the inside of the slowly-releasing shells, thereby loading the compound salt into the insides of the slowly-releasing shells, in order to make the flow smoother, the fifth motor 709 is started to cause the fifth motor 709 to drive the stirring paddle 708 to rotate, so that the soaked slowly-releasing shells are stirred, the efficiency of the compound salt entering the slowly-releasing shells is improved, the compound salt is uniformly dispersed in the dispersion liquid, after the soaking end is finished, the containing barrel 701 is lifted upwards by the first electric push rod 702 to reset, when the first motor 403 is started to rotate the screw 402, the sliding plate 401 will slide the sealed barrel 404 to the weighing mechanism 8 (from the state shown in fig. 4 to the state shown in fig. 6), at this time, the second electric push rod 804 is started to make the upper end of the output shaft of the second electric push rod 804 slide upwards against the sleeve 803, and then the sleeve 803 drives the sealing plate 802 to slide upwards, so that the upper side surface of the sealing plate 802 abuts against the lower side surface of the sliding plate 401 to seal the lower end of the sealed barrel 404, in addition, after the first electric push rod 702 is lifted upwards to the containing barrel 701, the sealing surface 703 blocks the lower end of the discharge pipe 509 (as shown in fig. 11), at this time, the inside of the sealed barrel 404 is in a sealed state, in this state, the suction pump 805 is started to make the suction pump 805 continuously pump the gas inside the sealed barrel 404, thereby performing low temperature distillation on the slow release shell inside the containing barrel 701 (avoiding the slow release shell from being deformed again), so as to distill out the dispersion liquid in the slow release shell (the stirring paddle 708 can also be driven by the fifth motor 709 to rotate during the low-temperature distillation process, so as to improve the efficiency of the low-temperature distillation), so that only the compound salt remains in the slow release shell, after the low-temperature distillation is performed for a period of time, the second electric push rod 804 is started to cause the output shaft of the second electric push rod 804 to slide downwards, so that the sealing plate 802 falls on the weighing plate of the electronic scale 801 (at this time, the output shaft of the second electric push rod 804 is not in contact with the sleeve 803, so that the sealing plate 802 is completely placed on the weighing plate of the electronic scale 801, so as to maintain the accuracy), then the first electric push rod 702 is started to cause the output shaft of the first electric push rod 702 to drive the containing barrel 701 to slide downwards, so that the lower end of the containing barrel 701 is placed on the sealing plate 802 (the output shaft of the first electric push rod 702 is connected with the containing barrel 701 in a mode of connecting shaft and a waist-shaped groove 701, the connecting shaft is fixed on the output shaft of the first electric push rod 702, the waist-shaped groove is formed in the side wall of the containing barrel 701), so that after the containing barrel 701 is placed on the sealing plate 802, the connecting shaft slides to the middle position of the waist-shaped groove, the weight of the containing barrel 701 is completely supported by the sealing plate 802 (as shown in fig. 10), the weight of each part is known, the weight of the slow release shell inside the containing barrel 701 can be measured through the electronic scale 801 at the moment, then the weight of the composite salt is calculated by combining the weight of the original slow release shell, if the weight of the anti-coagulation salt and the anti corrosion agent does not reach the standard, the sliding plate 401 is driven to move again through the moving part 4, the containing barrel 701 is driven to move to be right above the soaking barrel 3, then the containing barrel 701 is soaked inside the soaking barrel 3 again until the weight of the composite salt filled in the slow release shell reaches the standard.
Specifically, after the weight of the composite salt in the slow-release shell is qualified, the holding barrel 701 is moved to the position right above the transfer barrel 10 through the moving member 4 (as shown in fig. 7), at this time, the first electric push rod 702 is further used for prompting the first electric push rod 702 to slide the holding barrel 701 downwards, the discharge port 704 is contacted with the discharge hopper 9, the specific discharge hopper 9 comprises a feed port 901, the whole discharge hopper 9 is in a double-V structure, the discharge rod 902 is fixedly installed at the middle position, the slide rod 707 is jacked upwards by the discharge rod 902 to prompt the discharge port 704 to be communicated with the feed port 901, so that the slow-release shell in the holding barrel 701 flows into the interior of the transfer barrel 9 through the discharge hopper 9 for collection and transfer, and in order to quickly recover the deformation of the slow-release shell and prevent the composite salt from leaking, at this time, the transfer barrel 9 can be placed in a drying oven for heating so as to recover the shape thereof, and be matched with a soil layer with the slow-release shell, the manual mode is preferentially used during construction.
