Technical Field

[0001] The invention relates to the field of coating preparation, and more particularly to a composite nano waterproof and heat-insulating coating for buildings and a preparation method thereof. Background Art

[0002] At the construction site, it is usually necessary to select different types of coatings for different effects according to the actual situation on site to ensure that the protection method and the use environment match and protect the on-site equipment and environment; Patent No. CN202011480434.8 discloses a composite nano waterproof and heat-insulating coating for buildings and its preparation method, which belongs to the field of coating technology. The inventive coating includes the following raw materials in parts by weight: 150-200 parts of emulsion, 60-80 parts of waterborne polyurethane, 60-80 parts of filler, 60-80 parts of heat-insulating composite nanomaterials, 30-50 parts of organosilicon hydrophobic agent, 5-10 parts of film-forming aid, 3-6 parts of defoamer, and 3-6 parts of synergist. The invention adds a large amount of heat-insulating composite nanomaterials, and after two-step modification of acid etching and hydrophobicity, the hydrophobic and heat-insulating properties of the material are greatly improved. At the same time, the added synergist has a strong adhesion ability and can be firmly adsorbed on the surface of nanomaterials and filler particles, so that it can be stably dispersed in the coating, greatly reducing the subsequent peeling and cracking of the coating and extending the service life of the coating. However, the equipment is unable to refine the particles before applying the paint in accordance with the environment of the construction site. Summary of the invention

[0003] The purpose of the present invention is to provide a composite nano waterproof and heat-insulating coating for buildings and a preparation method thereof, which has the beneficial effects of ensuring the use environment and effect of on-site construction, further refining the coating, and ensuring that it is evenly applied and free of particles.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A method for preparing a composite nano waterproof and heat-insulating coating for buildings, the method comprising the following steps:

[0006] Step 1: Pour the coating to be screened and ground into the device; grind the coating by reverse synchronous reciprocating control of the screen grinder controlled by the variable frequency drive;

[0007] Step 2: The paint is tilted and continuously flows downward through the slots for screening;

[0008] Step 3: Through continuous frequency conversion driving, the two sieve plates are continuously combined and sheared to continuously refine the architectural coating;

[0009] Step 4: By adjusting the slope, changing the direction of paint accumulation, adjusting the grinding and screening effect, the paint in different environments can be processed and matched;

[0010] Step 5: The sieved and ground paint is accumulated at the lower end, and all valves are opened at the same time through control to distribute equal amounts of paint for separate use.

[0011] The screening grinder comprises a right folding plate, a left folding plate, a central adjustment shaft, a screening inclined groove and a conical grinding table. The inner ends of the right folding plate and the left folding plate are coupled and connected via the central adjustment shaft. The right folding plate and the left folding plate are both provided with a screening inclined groove and a conical grinding table. The conical grinding table is gap-inserted into the screening inclined groove for shearing and grinding.

[0012] The screening grinder is symmetrically arranged, and the outer wall of the conical grinding table and the inner wall of the screening inclined slope groove are both arranged to have a rough frosted surface.

[0013] The outer ends of the right folding plate and the left folding plate are both hinged on the side hinge rods for driving and restraining.

[0014] A coating prepared by a method for preparing a composite nano waterproof and heat-insulating coating for buildings, wherein the coating comprises synthetic resin, titanium dioxide, perlite and a defoaming agent.

[0015] Before the mixed waterproof and heat-insulating coating is used on the construction site, in order to ensure the use of unified standards for different coatings after refinement, the coating is poured into the device, and the falling coating is continuously filtered to remove impurities through the reciprocating control drive of the frequency conversion drive. At the same time, the coating is continuously ground and refined for use by grinding; the inclination direction is adjusted to change the flow position of the flowing accumulation coating, so that the coating flows into a smaller aperture and a smaller grinding distance, thereby changing the refinement grinding standard for grinding and refinement processing; after the processing and preparation are completed, the valve drive is controlled to recover the uniform amount of coating for use in an equal environment, thereby ensuring the use effect of the coating on the construction site.

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] As shown in the embodiment shown here,

[0030] Before the mixed waterproof and heat-insulating coating is used on the construction site, in order to ensure the use of unified standards for different coatings after refinement, the coating is poured into the device, and the falling coating is continuously filtered to remove impurities through the reciprocating control drive of the frequency conversion drive. At the same time, the coating is continuously ground and refined for use by grinding; the inclination direction is adjusted to change the flow position of the flowing accumulation coating, so that the coating flows into a smaller aperture and a smaller grinding distance, thereby changing the refinement grinding standard for grinding and refinement processing; after the processing and preparation are completed, the valve drive is controlled to recover the uniform amount of coating for use in an equal environment, thereby ensuring the use effect of the coating on the construction site.

[0035] Further basis Figure 2 , Figure 3 , Figure 4 and Figure 5 The working process of the example of a method for preparing a composite nano waterproof and heat-insulating coating for a building is as follows:

[0036] Through the rough frosted surface of the outer wall of the conical grinding table 6 and the inner wall of the inclined sieve groove 5, when the two symmetrically arranged sieve grinders are driven for processing, the paint flowing into the inclined sieve groove 5 is inserted by the conical grinding table 6, so as to realize the unblocking of the sieve and the grinding and refinement of the paint at the same time, which is convenient for the refinement and use of the paint on site, the paint is more uniform, the thickness is easier to control, and the building insulation effect is more uniform; the inner wall of the inclined sieve groove 5 at the upper end is a positive trapezoidal inclined slope block style, which is convenient for inserting and grinding the conical grinding table 6 during the tilting process, and automatically refining the processing in accordance with the tilting angle; the inner wall of the inclined sieve groove 5 at the lower end is an inverted trapezoidal inclined slope block style, which is also for the convenience of inserting the conical grinding table 6; the conical grinding table 6 is matched with the contact grinding with the inclined sieve groove 5 during the tilting process, so that all the surfaces of the conical grinding table 6 are conical inclined slopes, so as to avoid interference during the motion processing and affect the processing; combined with different positions, the corresponding conical grinding table 6 has different styles and sizes.

[0037] Further optimization in combination with the above embodiments:

[0038] Further basis Figure 2 , Figure 3 , Figure 4 and Figure 5 The working process of the example of a method for preparing a composite nano waterproof and heat-insulating coating for a building is as follows:

[0039] The side hinged rods 3 at the outer ends of the right folding plate 1 and the left folding plate 2 facilitate driving processing and at the same time restrain each other with the central adjustment shaft 4 to facilitate effective tilt adjustment of the tilt angle.

[0040] Further optimization in combination with the above embodiments:

[0041] Furthermore, the volume of the inclined sieve groove 5 and the conical grinding table 6 gradually decreases from the outside to the inside; the gap between the inclined sieve groove 5 and the conical grinding table 6 gradually becomes smaller from the outside to the inside.

[0042] This part is based on Figure 2 , Figure 3 , Figure 4 and Figure 5 The working process of the example of a method for preparing a composite nano waterproof and heat-insulating coating for a building is as follows:

[0043] By changing the inclination angles of the right folding plate 1 and the left folding plate 2, the paint accumulated at the inner end can be ground, screened and processed in a more refined manner; the paint accumulated at the outer end will have a relatively poorer refining effect, but the grinding speed is fast, and the paint can be adjusted and selected according to the actual situation at the construction site, making it easy to switch.

[0044] Further optimization in combination with the above embodiments:

[0045] Furthermore, the side hinge rod 3 slides in a longitudinally limited and sealed extension frame 12 extending outward from the preparation and processing box 14 through a limited and sealed sliding plate 7; the preparation and processing box 14 is fixed on a fixed platform 13.

[0046] This part is based on Figure 2 , Figure 3 , Figure 4 and Figure 5 The working process of the example of a method for preparing a composite nano waterproof and heat-insulating coating for a building is as follows:

[0047] By making the side hinged rod 3 slide in the extended sealing fixed frame 12 extending outward from the preparation and processing box 14 through the limiting sealing sliding plate 7, leakage is prevented when the right folding plate 1 and the left folding plate 2 are driven for processing; at the same time, the extended limiting sealing sliding plate 7 facilitates the driving combined connection.

[0048] Further optimization in combination with the above embodiments:

[0049] Furthermore, the lower end limit sealing sliding plate 7 is combined and connected through the lower rack connecting plate 9; the upper end limit sealing sliding plate 7 is combined and connected through the upper rack connecting plate 8; the upper rack connecting plate 8 and the lower rack connecting plate 9 are respectively meshed and connected to the two ends of the driving gear 11 on the frequency conversion driver 10, and the frequency conversion driver 10 is fixed on the fixed platform 13 through the motor seat.

[0050] This part is based on Figure 2 , Figure 3 , Figure 4 and Figure 5 The working process of the example of a method for preparing a composite nano waterproof and heat-insulating coating for a building is as follows:

[0051] The frequency conversion driver 10 controls the driving gear 11 to switch between forward and reverse rotation, thereby driving the upper rack connecting plate 8 and the lower rack connecting plate 9 to respectively drive the symmetrical screen grinders to move in opposite directions or towards each other at the same time, thereby causing the screen inclined slope groove 5 and the conical grinding table 6 on the right folding plate 1 and the left folding plate 2 to continuously reciprocate for grinding, refining and dredging processing, thereby completing the refining processing of the paint at the construction site.

[0052] Further optimization in combination with the above embodiments:

[0053] Furthermore, the center adjustment shaft 4 is limitedly slid in a center slider 15 for facilitating synchronous sliding. The center slider 15 is connected to a tilt adjustment screw 17 by bolts. The tilt adjustment screw 17 rotates in a fixed seat 16 fixed on the center adjustment shaft 4 to adjust the center adjustment shaft 4. The tilt adjustment screw 17 rotates in an extended sealing fixed frame 12 at the middle end.

[0054] This part is based on Figure 8 , Fig. 9 , Fig.10 and Fig.11 The working process of the example of a method for preparing a composite nano waterproof and heat-insulating coating for a building is as follows:

[0055] By rotating the tilt adjustment screw 17 on the extended sealing fixed frame 12 at the middle end, the tilt adjustment screw 17 drives the fixed seat 16 and the center adjustment shaft 4 to slide in the center slider 15 through threaded cooperation to change the position. At the same time, the right folding plate 1 and the left folding plate 2 are restrained by the fixed side hinge rod 3, so that the tilt position of the right folding plate 1 and the left folding plate 2 is changed at the same time, and the symmetrical setting needs to be changed and adjusted synchronously; thereby, the position of the accumulated paint is changed, thereby changing the refinement efficiency and effect.

[0056] Further optimization in combination with the above embodiments:

[0057] Furthermore, a closed thread baffle 18 is slidably inserted in the fixed platform 13, and the closed thread baffle 18 is connected to the forward and reverse screw shafts 19 through forward and reverse threads, and the forward and reverse screw shafts 19 are connected to the transmission shaft of the valve driver 20 through a coupling.

[0058] A coating prepared by a method for preparing a composite nano waterproof and heat-insulating coating for buildings, wherein the coating comprises synthetic resin, titanium dioxide, perlite and a defoaming agent.

[0059] This part is based on Figure 8 , Fig. 9 , Fig.10 and Fig.11 The working process of the example of a method for preparing a composite nano waterproof and heat-insulating coating for a building is as follows:

[0060] The forward and reverse screw shafts 19 are driven to rotate through the valve driver 20, and the closed threaded baffle 18 is driven to open and close at the lower end of the fixed platform 13 through the cooperation of the forward and reverse threads, so that the accumulated refined paint falls at the same time for quantitative use packaging and actual coating according to the on-site conditions and positions.
