BRIEF DESCRIPTION OF DRAWINGS

[0045] Figure 1 is a flowchart of the construction method of the anti-skid paint provided by the embodiment of the application. DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0047] It should be noted that the terms "comprise" and "specific" and any variants thereof in the application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device comprising a series of steps or units does not have to be limited to the clearly listed steps or units, but can include other steps or units that are not clearly listed or inherent to the process, method, product or device.

[0048] Please refer to Figure 1 , Figure 1 is a flowchart of the construction method of the anti-skid paint provided by the embodiment of the application. The construction method of the anti-skid paint comprises the following steps.

[0049] S1, when it is detected that the anti-skid coating after the finish paint construction is in a semi-dry state, anti-skid granule scattering is performed on the anti-skid coating for several times;

[0050] S2, after each anti-skid granule throwing, detecting the throwing uniformity of the anti-skid granule in the target area covered by the current throwing;

[0051] S3, if the detection result is lower than the preset uniformity threshold, improving the throwing mode of the next anti-skid granule throwing according to the detection result;

[0052] S4, performing the next anti-skid granule throwing according to the improved throwing mode until the detection result of the next anti-skid granule throwing is not lower than the preset uniformity threshold or until the anti-skid coating completes the anti-skid granule throwing.

[0053] It is worth mentioning that the throwing is a gradual process, and there may be uneven phenomena in the process. Analyzing the uniformity of the throwing can improve the subsequent throwing mode in time. The anti-skid effect is enhanced from two aspects. The first is the composition of the anti-skid coating, which mainly determines the anti-skid effect of the anti-skid coating and is the basis of the anti-skid effect. The second is the way in the construction stage. Although the coating has good anti-skid effect, the steps and points for attention in construction are the key to whether the performance of the anti-skid coating can be truly played. The embodiment of the present application detects the uniformity of the anti-skid granule to detect the quality of the coating, which can detect the anti-skid granule non-throwing area and the anti-skid granule over-concentration throwing area. The anti-skid coating is mainly composed of film-forming resin, anti-skid granule, additive, pigment and the like. Each component is mixed uniformly according to the set proportion to form a stable anti-skid coating system.

[0054] Specifically, the step S2 comprises:

[0055] S21, after each anti-skid granule throwing, acquiring image data of the target area covered by the current throwing;

[0056] S22, determining the area of the target area and the position points of the anti-skid granule according to the image data;

[0057] S23, calculating the distance between each position point and a plurality of adjacent position points to obtain a distance set of each position point;

[0058] S24, calculating the distance variance of all position points according to the average value of the distance set of each position point;

[0059] S25, determining the abnormal area of the target area according to the average value and the distance variance;

[0060] S26, obtaining the detection result of the throwing uniformity detection according to the target area and the abnormal area.

[0061] Specifically, the abnormal region of the target region is determined according to the average value and the distance variance.

[0062] An abnormal position point of the target region is determined according to the average value and the distance variance.

[0063] An abnormal region of the target region is obtained according to the abnormal position point.

[0064] For example, before the topcoat is cured, the anti-skid granules are scattered on the topcoat in a scattering manner. In the embodiment of the present application, the anti-skid granules are natural rubber particles, and the particle size ranges of the natural rubber particles are 0.7-1.1 mm and 1.5-1.9 mm respectively. The particle size is selected to achieve the best anti-skid effect of the power plant floor and reduce the influence of the plum rain season. The particle size can be selected according to the specific construction environment. When scattering, the scattering must be uniform. The object region (anti-skid coating) is scattered in a continuous N times small amount scattering manner to avoid excessive scattering and to avoid compensation. Uniform scattering can better increase the friction and the anti-skid effect. The uniformity of the anti-skid granule scattering is detected. The image processing-based method is used to detect the floor after construction. In order to collect images with obvious contrast, the color contrast between the pigment powder and the natural rubber particles is obvious, or there is a color with obvious contrast in different color channels of the image. The image of the anti-skid floor is collected in a following scattering vehicle manner, so that the image data can be obtained in time, the uniformity of the scattering is analyzed, and the subsequent scattering manner is improved in time. For example, the floor image is obtained by a camera; the region (target region) on the image corresponding to the single scattering region is intercepted and recorded as region The area of the region is calculated The position points of the natural rubber particles on the image are extracted on the region The distances between the position points and adjacent position points are calculated , , wherein, n represents the number of natural rubber particles, and the subscript represents the number of position points around the natural rubber particles; the principle is followed that there is no other position point on the line between adjacent position points; the average value of the distances of the position points is calculated , , The variance of the distances of the position points is obtained , , ; judge whether the average value and variance of the distance of each position point is greater than a prescribed threshold value (the threshold value is required to be set according to different ground requirements and different particle sizes of the scattering, and different anti-skid requirements, the threshold value is different in different cases, and the threshold value can be 0.5 mm, 1 mm, 5 mm, etc.), as long as one does not meet the requirements, the area has uneven points; if the average value is less than the prescribed threshold value, it is considered that the scattering is too concentrated, and the area of the image of the scattering area is calculated ; connect the uneven points between adjacent points with straight lines to form a region, and calculate the total area of the edge of the formed region in the image These uneven points will not be single as long as they appear, and generally multiple points will appear in an area as long as they appear, and a closed region can be connected, and the region cannot contain points judged to be uniform, so the division of the region should follow this principle; the uneven degree (which is a percentage, calculated according to the area before, and has no meaning in the distance value) is , if it is less than the set value, it is considered qualified, otherwise it is not qualified. The embodiment of the application can detect the non-scattering area of natural rubber particles and can also detect the over-concentration area of natural rubber particles. After the particle scattering is completed, the paint is completely dried.

[0065] Further, before detecting that the anti-skid coating after the topcoat construction is in a semi-dry state, the method further comprises:

[0066] S101, ground pretreatment is performed on the construction area;

[0067] S102, a mixed film-forming resin is used to perform primer construction on the pretreated construction area;

[0068] S103, a mixed film-forming resin is used to perform topcoat construction on the primer-constructed construction area.

[0069] Exemplarily, the ground of a power plant workshop is constructed with anti-skid paint to achieve the effect of anti-skid.

[0070] The construction process comprises the following steps: (1) ground finishing: when laying anti-skid paint on the ground, the ground needs to be treated, including cleaning, leveling and drying, to improve the adhesion of the ground. In order to obtain a clean and tidy ground and exclude the influence of other substances on the anti-skid effect, the oil stains, dust and other impurities on the ground need to be cleaned. In the present application, the construction area is first closed, the ground is cleaned with high-pressure gas, and the ground is cleaned with high-pressure gas for 24 hours. After the cleaning is finished, the dust in the air is collected using air purification gas. After cleaning, in order to make the flatness of the ground meet the requirements and improve the anti-skid effect, the area to be constructed is leveled and repaired by grinding and sand blasting. After leveling and repairing, the ground is dried to make the water content of the ground meet the requirements of construction. The ground to be constructed needs to be cleaned again before paint application, which is the last cleaning to provide the best environment for painting.

[0071] (2) primer construction: the prepared film-forming resin, which has added additives and water-based pigments, is checked for the presence of bubbles, which is a key step for painting. Bubbles can seriously affect the forming effect of the film-forming resin and also affect the anti-skid effect. The primer is applied to the cleaned ground by brushing, rolling or spraying, etc. During the primer construction process, the thickness and uniformity of the primer need to be controlled, because too thick a coating can cause cracking or peeling, and too thin a coating can affect the anti-skid effect. The primer is constructed for 4 times, and enough drying time is left between each layer of paint to obtain the best coating effect.

[0072] (3) topcoat construction: after the primer construction is completed, the prepared film-forming resin, which has added additives and water-based pigments, is checked for the presence of bubbles, which is similar to the primer. It should be noted that the primer and topcoat can be constructed by brushing, rolling or spraying, etc.

[0073] Specifically, the film-forming resin comprises water-based epoxy resin, water-based pigment and additive, the preparation method of the water-based epoxy resin is:

[0074] The modified epoxy resin is prepared according to the epoxy resin, anhydrous ethanol and ethylene glycol butyl ether;

[0075] The emulsifier is prepared according to the polyethylene glycol and the epoxy resin;

[0076] The water-based epoxy resin is prepared according to the modified epoxy resin and the emulsifier.

[0077] It is worth noting that the film-forming resin is the base material of the anti-slip coating, providing the film-forming purpose for the entire anti-slip coating. Phenolic resins, alkyd resins, chlorinated rubbers, epoxy resins, or polyurethane resins are typically selected. Film-forming resins are generally used in primer and topcoat coatings. Their film-forming purpose is twofold: firstly, to fix the anti-slip particles; and secondly, to protect the substrate from damage. In this embodiment of the invention, the substrate is the floor or ground of a power plant. In this embodiment of the invention, water-based epoxy resin is selected as the main component of the film-forming resin, with the addition of water-based pigments and additives. Water-based epoxy resin is environmentally friendly, non-toxic, easy to apply, and has good anti-slip properties. With the addition of anti-slip particles, the anti-slip performance of the coating can be improved.

[0078] More specifically, the preparation of modified epoxy resin based on epoxy resin, anhydrous ethanol, and ethylene glycol butyl ether includes:

[0079] Epoxy resin, anhydrous ethanol, and ethylene glycol butyl ether were added to the first reactor according to the preset proportions.

[0080] The interior of the first reactor is heated to 60°C and maintained at a constant temperature.

[0081] The substances in the first reactor are brought to a molten state by stirring.

[0082] Nitrogen gas is introduced into the first reactor, and after the air in the first reactor is purged, p-aminobenzoic acid is added into the first reactor.

[0083] The internal temperature of the first reactor is raised to 80°C and maintained at a constant temperature. After the reaction is continued for a predetermined time, a modified epoxy resin is obtained.

[0084] For example, by portion ratio Epoxy resin, anhydrous ethanol, and ethylene glycol butyl ether are added to a reactor. The reactor is heated to 60°C and maintained at that temperature. The mixture is then stirred until it melts. Nitrogen gas is introduced to purge air from the reactor. Next, p-aminobenzoic acid, a modified substance, is added. The reactor temperature is raised to 80°C and maintained at that temperature for a predetermined reaction time (which can be set as needed). This yields the modified epoxy resin. It is understandable that due to the inherent drawbacks of epoxy resin, it can negatively impact anti-slip coatings used on power plant floors. To make anti-slip coatings suitable for power plant floors and overcome the shortcomings of traditional epoxy resins, a modified epoxy resin needs to be prepared before preparing the waterborne epoxy resin. This modified epoxy resin can effectively improve the adhesion, anti-slip properties, and durability of the anti-slip coating.

[0085] More specifically, the preparation of the emulsifier based on polyethylene glycol and the epoxy resin includes:

[0086] The polyethylene glycol and the epoxy resin are put into the second reactor as raw materials according to a preset proportion, the inside of the second reactor is heated to 90℃ and kept constant, so that the substances in the second reactor are in a molten state;

[0087] After the reactants in the second reactor are fully mixed by stirring for 30 min;

[0088] After the temperature in the second reactor is raised to 180℃ and kept constant for a period of time, a certain proportion of potassium persulfate is added as a catalyst, and the constant temperature is kept for a predetermined time to obtain an emulsifier.

[0089] For example, the polyethylene glycol and the epoxy resin are put into the reactor as raw materials according to a preset proportion The polyethylene glycol and the epoxy resin are put into the reactor as raw materials according to a preset proportion

[0090] More specifically, the preparation of the water-based epoxy resin from the modified epoxy resin and the emulsifier comprises:

[0091] The modified epoxy resin and the emulsifier are added to the third reactor according to a preset proportion, stirred and fully mixed, and deionized water is added dropwise;

[0092] When phase inversion occurs, deionized water is added to adjust the solid content, and a water-based epoxy resin is obtained.

[0093] For example, the polyethylene glycol and the epoxy resin are put into the reactor as raw materials according to a preset proportion The modified epoxy resin and the emulsifier are added to the reactor, stirred and fully mixed, and deionized water is added dropwise. When phase inversion occurs, a certain amount of deionized water is added to adjust the solid content, and a water-based epoxy resin emulsion is obtained.

[0094] Specifically, the preparation method of the water-based pigment is:

[0095] The surfactant, dispersant, cosolvent, defoamer, and deionized water are added to the dispersion preparation device, stirred uniformly, and then the pigment powder is added to the dispersion preparation device at a rotation speed of 1200 r / min and dispersed for 3 hours. After standing, filtering, and standing again, a water-based pigment is obtained.

[0096] The water-based pigment is used for preparing various colors, which can not only make the ground of the factory beautiful, but also distinguish different functions or safety levels of the factory area. The preparation method of the water-based pigment is as follows: adding surfactant, dispersant, cosolvent, defoaming agent and deionized water in a dispersion preparation device according to needs, stirring uniformly, then adding pigment powder, the rotation speed of the sand mill is 1200r / min, dispersing for 3h, standing, filtering, standing again, filtering again, and obtaining the water-based pigment.

[0097] Specifically, the additives help to improve the performance and application performance of the paint, and there are many kinds of additives, mainly including: curing agent, the curing agent can be selected as amidoamine or polyamide. It can promote the curing reaction of the film-forming resin, control the curing process of the film-forming resin, ensure that the coating is completely cured within a specified time, and form a strong coating. The curing agent can also improve the anti-skid performance, which can significantly improve the friction coefficient of the ground, thereby reducing the risk of slipping and falling;

[0098] Defoaming agent, also known as bubble removing agent or bubble breaking agent, can produce many foams affecting production in the process of industrial production, and the defoaming agent needs to be added;

[0099] The leveling agent is a commonly used paint additive, which can promote the formation of a flat, smooth and uniform coating film during the drying and film-forming process of the paint. There are many types of leveling agents, and the types of leveling agents used for different paints are not the same.

[0100] In addition to the above-mentioned additives, wetting agent, thixotropic agent, anti-aging agent, light stabilizer, flame retardant, toughening agent, etc. are generally added in the anti-skid paint, which can be added according to actual needs. The water-based epoxy resin, additives, water-based pigment are mixed according to needs, and wetting agent, thixotropic agent, anti-aging agent, light stabilizer, flame retardant, toughening agent, etc. can also be added to obtain the final required film-forming resin.

[0101] Further, before detecting that the anti-skid coating after the topcoat construction is in a semi-dry state, the method further comprises:

[0102] S104, the surface of the anti-skid granules is modified.

[0103] It is worth mentioning that the anti-skid granules are additives to improve the anti-skid performance of the paint film, and the film-forming resin used in the coating itself has a certain anti-skid effect, and the anti-skid granules play a great role in greatly imparting the anti-skid ability of the paint film to achieve the required anti-skid effect. The anti-skid granules can be rubber-based elastic granules or hard granules to increase friction and anti-skid effect. Surface treatment of the anti-skid granules can increase the adhesion of the anti-skid granules to the base (film-forming resin), reduce the wear rate, and improve the service life of the anti-skid coating. When used in the coating of the factory floor, it can prevent people from slipping and falling. The anti-skid granules select natural rubber particles, wherein the particle size of the natural rubber particles has two main ranges, 0.7-1.1mm and 1.5-1.9mm; other particle size ranges of natural rubber particles can also be used on the floor of different areas in the factory to distinguish the requirements of different areas, such as the particle size range near some equipment can be 1.5-1.9mm and 4.2-4.7mm. After selecting the type of anti-skid granules, the surface of the anti-skid granules needs to be treated due to the influence of the surface of the granules. Take the commonly used natural rubber granules with particle size ranges of 0.7-1.1mm and 1.5-1.9mm as examples for specific description and illustration.

[0104] In order to eliminate the influence of smooth surface of natural rubber particles and adhesion of impurities, and improve the bonding strength between natural rubber particles and film-forming resin, NaOH saturated solution is selected, and natural rubber particles are uniformly added to the NaOH solution at a fixed weight per minute, and stirring of the NaOH solution is maintained during the addition (the purpose is to reduce the mixing step of natural rubber particles, and sufficient mixing can be achieved here), after the natural rubber particles are added, stirring is maintained for 5min, and then it is placed for 25min, filtered, washed, and finally dried by continuous ventilation at a ventilation temperature of 35℃, to obtain the anti-skid granules.

[0105] The embodiment of the present application selects natural rubber particles of different particle sizes, which can make the anti-skid granules lay on the film-forming resin more uniformly, and the anti-skid particles of different particle sizes can compensate for each other in uniformity, solving the problem that conventional and single particle size anti-skid particles are prone to uneven scattering. The natural rubber particles of different particle sizes of the embodiment of the present application do not need to be mixed separately, and it is verified by testing that they are uniformly stirred during surface treatment, and the uniformity meets the requirements. After the surface treatment of the natural rubber particles of the embodiment of the present application, the original smooth surface disappears, the roughness of the surface is improved, and the adhesion between the natural rubber particles and the film-forming resin is enhanced.

[0106] Alternatively, the anti-skid granules can also select waste tires and polyurethane elastomer particles, or silica powder, silicon carbide, and diamond sand, but all need to be modified on the surface.

[0107] The construction method of the anti-skid paint disclosed by the embodiment of the present application can improve the construction of the anti-skid paint by introducing the uniformity detection step of the anti-skid particle throwing, so as to solve the problem of poor anti-skid effect of the anti-skid paint in a high-humidity environment, improve the anti-skid effect of the anti-skid paint, and thus meet the application requirements of higher anti-skid effect level.

[0108] The above is the preferred embodiment of the present application. It should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application. These improvements and refinements are also considered within the scope of protection of the present application.
