[0041] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0042] The first embodiment of the present application is:

[0043] See also Figures 1 to 3 ,in Figure 1It is a schematic diagram of the steps of the facade reflective coating spraying construction method according to the first embodiment of the present invention. Figure 2 Schematic diagram of the steps of test spraying of the spray gun according to the first embodiment of the present invention. Figure 3 It is a schematic diagram of the spraying steps of the spray gun according to the first embodiment of the present invention.

[0044] The present invention provides a method for spraying a facade reflective coating, comprising the following steps:

[0045] S101: Prepare qualified facade reflective paint and diluent;

[0046] S102: Prepare protective equipment for construction workers;

[0047] S103: Inspect and process the facade base that needs to be sprayed with paint;

[0048] S104: Stir the coating thoroughly and evenly to ensure that the components inside are evenly distributed;

[0049] S105: Select the appropriate spray gun according to the construction situation;

[0050] S106: Pour the paint into the spray gun container and perform a test spray, and then use the spray gun to perform spraying construction operations according to spraying requirements;

[0051] S107: Clean the spray gun and other construction tools, clear the debris on the site, and dispose of waste.

[0052] Specifically, the construction personnel confirm that the paint preparation and production information is correct, ensure that all performance indicators meet the construction requirements, prepare an appropriate amount of matching diluent according to the actual viscosity of the paint and the construction conditions. If the paint is too thick and is not conducive to the normal atomization and spraying of the spray gun, you can use the corresponding environmentally friendly diluent to dilute it in a certain proportion, but the dilution ratio must be strictly controlled. Generally, it should not exceed 10%-15% of the total amount of paint to avoid excessive dilution affecting the reflective and bonding properties of the paint. Prepare the personal protective equipment required by the construction personnel, such as protective glasses, gas masks, solvent-resistant gloves, etc., to ensure the health and safety of the construction personnel, and thoroughly inspect and treat the facade base that needs to be sprayed with paint. Remove dust, oil, rust, loose old coatings and other impurities from the surface to make the surface of the base layer flat, dry and solid. Then wipe the surface of the base layer with a clean damp cloth to ensure that there are no residual impurities to create conditions for good adhesion of the paint. Stir the paint thoroughly and evenly to make the internal components uniformly distributed to avoid precipitation, stratification and other conditions that affect the construction effect. Select an air spray gun according to the construction situation and equip it with a corresponding air compressor to provide a stable source of compressed air to ensure the normal operation of the spray gun. Pour the prepared facade reflective paint into the paint container of the spray gun. Then adjust the paint flow regulating valve of the spray gun according to the actual viscosity of the paint and the performance of the spray gun to control the amount of paint sprayed. Generally, it can be set at a moderate position initially and adjusted according to the actual viscosity of the paint and the performance of the spray gun. Test spraying is carried out on a small sample plate of the same material as the construction facade, or an inconspicuous corner of the construction facade is selected for test spraying, and fine-tuning is made according to the test spraying effect. After the fine-tuning is completed, the paint is sprayed on the facade base through the spray gun. After the spraying construction is completed, the spray gun is immediately cleaned to prevent the paint from drying and clogging inside the spray gun. Other construction tools such as stirring tools and paint containers are also cleaned in time. At the same time, the remaining paint, thinners and other debris around the construction site are cleaned up, and the waste materials are classified, collected and processed in accordance with environmental protection requirements to keep the construction site clean and tidy, and to avoid the impact of waste on the surrounding construction environment. The automatic and rapid spraying of the spray gun reduces the time required for construction, thereby improving the construction efficiency of construction personnel.

[0053] S111: pouring the prepared facade reflective paint into the paint container of the spray gun, and starting a stirring tool to fully stir the paint again;

[0054] S112: Test spraying on a small sample panel of the same material as the actual facade to be constructed.

[0055] Specifically, pour the prepared facade reflective paint into the paint container of the spray gun, start the stirring tool to fully stir the paint again to make it uniform and free of precipitation to ensure the spraying quality of the paint, conduct a trial spraying on a small sample plate of the same material as the actual construction facade, or choose an inconspicuous corner of the construction facade for trial spraying, observe the atomization effect of the paint, the fan width of the spray, the coverage of the paint, and the reflective effect, etc. According to the trial spraying situation, adjust the parameters such as the pressure of the spray gun, the distance between the nozzle and the sample, and the moving speed of the spray gun until a satisfactory spraying effect is obtained to ensure that the expected coating quality requirements can be achieved during the formal construction. During the trial spraying process, pay attention to record the appropriate parameter settings as a reference for the formal construction.

[0056] S131: The spray gun sprays from top to bottom and from left to right, first pre-spraying the edges and corners of the facade, and then spraying evenly over a large area;

[0057] S132: The movement speed of the spray gun should be moderate and uniform;

[0058] S133: There should be appropriate overlap between the fan-shaped areas sprayed by the spray gun.

[0059] Specifically, spraying is usually carried out from top to bottom and from left to right, which can prevent the paint from flowing and covering the sprayed area, ensuring uniform coating. Pre-spray the edges, corners and other parts of the facade first, so that these places that are difficult to spray can be covered with a layer of paint first, and then spray a large area evenly. The movement speed of the spray gun should be moderate and uniform, generally controlled between 30-60cm / s. During the movement, the spray gun should remain stable to avoid shaking, speeding up and slowing down, etc., so that the paint can be evenly covered on the facade to form a flat, uniformly thick coating. At the same time, there should be appropriate overlap between the sprayed fan-shaped areas, and the overlap width is generally controlled at about 1 / 3-1 / 2 of the fan-shaped width. Reasonable overlap can ensure the uniformity and integrity of the coating, avoid the appearance of striped spray-missing areas, and make the reflective effect and appearance quality of the entire facade reach the best state.

[0060] A facade reflective paint spraying construction method implemented in this embodiment reduces the time required for construction through automatic and rapid spraying of the spray gun, thereby improving the construction efficiency of construction workers.

[0061] The second embodiment of the present application is:

[0062] Based on the first embodiment, please refer to Figure 4 and Figure 5 , Figure 4 It is a schematic structural diagram of a facade reflective coating spraying construction device according to a second embodiment of the present invention. Figure 54 is a schematic structural diagram of an auxiliary module according to a second embodiment of the present invention.

[0063] The present invention provides a facade reflective paint spraying construction device, which also includes a supply module 201, a spray gun module 202, a control module 203 and an auxiliary module 204, wherein the auxiliary module 204 includes a stirring unit 205 and a filtering unit 206.

[0064] The spray gun module 202 is connected to the supply module 201 , the control module 203 is connected to the spray gun module 202 , and the auxiliary module 204 is connected to the supply module 201 .

[0065] The supply module 201 is used to contain the facade reflective paint and realize stable and quantitative delivery of the paint;

[0066] The spray gun module 202 is used to compress, store and release air so that the paint can be well atomized and sprayed under the action of the released compressed air;

[0067] The control module 203 is used to control the spraying and stopping of the paint in the spray gun module 202, and can also finely adjust the spraying pressure and flow rate of the sprayed paint;

[0068] The auxiliary module 204 is used to improve the quality of the paint in the supply module 201 .

[0069] The supply module 201 can hold the facade reflective paint and is a paint storage tank. The supply module 201 is used to ensure that there is sufficient paint supply during the construction process to avoid frequent addition of paint affecting the construction efficiency. At the same time, a pipeline is used to connect with the spray gun module 202, and a paint pump is used to achieve stable and quantitative delivery of the paint to ensure that the spray gun can continuously obtain a uniform paint flow and ensure the consistency of the spraying effect. The material of the delivery pipeline must have good corrosion resistance to prevent chemical reactions with the paint that affect the quality of the paint. The spray gun module 202 is an air compressor and a spray gun body. When an air spray gun is used for spraying construction, the air compressor can compress and store air to provide a stable and adjustable spray gun body. The compressed air source enables the paint to be atomized and sprayed well from the nozzle of the spray gun body under the action of compressed air to form uniform paint droplets, thereby achieving the purpose of spraying the facade base layer. The control module 203 can control the spraying and stopping of the paint in the spray gun module 202. At the same time, the spraying pressure and flow rate of the paint can be finely adjusted according to factors such as the properties of the paint, the construction environment conditions and the desired spraying effect, so that the atomization and coverage of the paint are in the best state, ensuring the uniformity of the coating quality. The auxiliary module 204 can improve the quality of the paint in the container of the supply module 201 to avoid the paint affecting the spraying of the spray gun module 202.

[0070] The stirring unit 205 is connected to the supply module 201, and the filtering unit 206 is connected to the supply module 201.

[0071] The stirring unit 205 is used to prevent the coating from settling or stratifying in the storage container or the delivery pipeline;

[0072] The filtering unit 206 is used to remove large particle impurities and inadequately dispersed agglomerates in the coating.

[0073] The stirring unit 205 can prevent the paint from precipitating, stratifying, etc. in the storage container or the delivery pipeline, which would affect the spraying quality of the spray gun module. The stirring unit 205 is a small electric stirrer, which is directly inserted into the storage container of the paint supply module 201 for timed stirring. The filtering unit 206 can remove large particles of impurities and inadequately dispersed agglomerates that may exist in the paint, thereby ensuring that the spray gun will not be blocked by impurities and affect normal spraying, and ensuring that the coating surface is smooth and the reflective effect is uniform. A filter is usually set on the paint delivery path of the supply module 201 for filtering and intercepting impurities, so that pure paint can enter the spray gun module 202 for spraying, thereby preventing the paint from containing impurities and affecting the spraying of the spray gun module 202.
