Description

Technical Field

[0001] This invention relates to the field of building materials production technology, and in particular to a plastering mortar for external wall insulation and its preparation method. Background Technology

[0002] Mortar applied to the surface of buildings or building components is collectively referred to as finishing mortar. Based on their function, finishing mortar can be divided into ordinary finishing mortar, decorative mortar, and finishing mortar with certain special functions (such as waterproof mortar, heat-insulating mortar, sound-absorbing mortar, and acid-resistant mortar). Finishing mortar requires good workability, easily applied as a uniform and smooth thin layer for convenient construction. It should also have high adhesion, ensuring the mortar layer bonds firmly to the substrate without cracking or peeling over time. In damp environments or areas susceptible to external forces (such as floors and wainscoting), it should also possess high water resistance and strength. The preparation and production of finishing mortar requires the use of mixing equipment to combine the various raw materials.

[0003] Common mortar mixing equipment typically involves pouring various mortar materials into the mixing equipment in a single batch according to a set ratio. This allows the equipment to mix a large quantity of mortar materials. However, because a large amount of mortar material is poured in at once, the equipment cannot effectively mix the materials, resulting in a longer mixing time. Furthermore, since the mortar materials are poured into the same location within the equipment, the materials cannot be dispersed throughout, impacting the mixing efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plastering mortar for external wall insulation and its preparation method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An external wall insulation plastering mortar and its preparation method are disclosed. The raw material formula of the external wall insulation plastering mortar includes the following components in the indicated weight ratios:

[0007] The ingredients are: 20-45 parts silicate cement, 10-30 parts sand, 2-5 parts lime, 2-5 parts clay, 0.2-0.8 parts organic fiber, 0.7-1.5 parts gypsum, 1-3 parts adhesive powder, and a bulk density of 400-550. 3-7 parts of clay sand.

[0008] Preferably, the preparation method of the plastering mortar for external wall insulation includes the following steps:

[0009] Step 1: Take the materials according to the stated weight ratio and place the materials in the storage box on the mixing equipment;

[0010] Step Two: Staff members perform initial mixing of the raw materials located in the storage box;

[0011] Step 3: After the initial mixing, the raw materials enter the mixing equipment. The mixing equipment continuously mixes the raw materials and injects water into the mixing equipment according to the specific gravity of the raw materials, so that the water and raw materials are evenly mixed to obtain the plastering mortar for external wall insulation.

[0012] Preferably, the mixing equipment for the plastering mortar for external wall insulation includes a mixing tank, a storage box installed on the top of the mixing tank, a feed hole opened at the bottom of the storage box, the storage box communicating with the interior of the mixing tank through the feed hole, a fixed cylinder installed inside the mixing tank, both ends of the fixed cylinder penetrating the mixing tank, a connecting sleeve rotatably installed at one end of the fixed cylinder, and several water outlet holes opened on the outer wall of the fixed cylinder.

[0013] Preferably, the end of the fixed cylinder away from the connecting sleeve is connected to the output shaft of the motor via a coupling. Both ends of the fixed cylinder are equipped with mounting rings, which are installed on the inner wall of the mixing tank. Several fixing rods are installed on the outer wall of the mounting rings. A rotating ring is installed at the end of the fixing rod away from the mounting ring, and several support plates are installed on the opposite surfaces of the two rotating rings.

[0014] Preferably, the side of the support plate has a plurality of mounting holes, a stirring rod is slidably mounted in the mounting holes, a limit ball is mounted on one end of the stirring rod near the inner wall of the mixing tank, and a spring is mounted on the stirring rod between the support plate and the limit ball.

[0015] Preferably, a limiting plate is installed on the stirring rod, and the limiting plate and the limiting ball are located on both sides of the support plate.

[0016] Preferably, the storage box has sliding grooves on both inner walls, and a baffle is installed inside the storage box. The baffle is slidably installed in the two sliding grooves on both sides, one end of the baffle penetrates through the storage box, and a through hole is opened on the side of the baffle away from the sliding groove.

[0017] Preferably, a support rod is installed on the inner wall of the feed hole, and a rotating plate is rotatably installed on the support rod. Both sides of the rotating plate are provided with mounting grooves along the length direction. A rubber strip is installed on the inner wall of the mounting groove, and one side of the rubber strip passes through the mounting groove.

[0018] Preferably, the rotating plate is located below the baffle plate, and the bottom of the inner walls on both sides of the feed hole is provided with a ramp. The motor and the connecting sleeve are respectively installed at both ends of the mixing tank.

[0019] Preferably, a discharge pipe is installed at the bottom of the mixing tank, the top of the discharge pipe is connected to the interior of the mixing tank, a flow control valve is installed on the discharge pipe, a base plate is installed at both ends of the mixing tank, a support frame is installed at both ends of the top of the base plate, and the top of the support frame is installed on the side of the mixing tank.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] In this invention, when the stirring rod stirs the raw materials, the stirring rod and its limiting ball can push the rotating plate to rotate. The raw materials located on the rotating plate fall into the mixing tank through the space between the rotating plate and the inner wall of the feed hole. During use, this allows the mortar raw materials to continuously enter the mixing tank for mixing, preventing a large amount of mortar raw materials from being placed directly inside the mixing tank, which would make it difficult for the stirring rod to mix the raw materials, resulting in a longer mixing time and uneven mixing. During use, the rotation angle of the rotating plate can be adjusted by adjusting the position of the limiting plate, thus adjusting the feeding speed of the mortar raw materials. During use, the raw materials located on the rotating plate can be continuously and alternately fed into both sides of the mixing tank through the two sides of the rotating plate, allowing various mortar raw materials to be more evenly distributed into the mixing tank, facilitating the mixing rod's stirring of the mortar raw materials.

[0022] In this invention, while the stirring rod is mixing the raw materials, the operator can continuously inject water into the fixed cylinder to pressurize the inside of the fixed cylinder, so that the water inside the fixed cylinder is sprayed into the mixing tank through the water outlet. The stirring rod can then stir and mix the mortar raw materials and water. In use, the stirring rod can both adjust the feeding position of the raw materials and stir and mix the mortar raw materials inside the mixing tank.

[0023] In this invention, after the mixing tank is used up, the operator can quickly inject water into the inside of the fixed cylinder through the water injection pipe. The water inside the fixed cylinder is then sprayed onto the inner wall of the mixing tank by the water pressure inside the fixed cylinder. The motor drives the fixed cylinder to rotate, so that the water inside the fixed cylinder is evenly rinsed on the inner wall of the mixing tank, the stirring rod, and the support plate as the fixed cylinder rotates. During use, there is no need for the operator to manually clean the inside of the mixing tank, making it more convenient to use. When in use, the fixed cylinder can both drive the stirring rod to stir the mortar raw materials and inject water into the raw materials during the mixing process, while also rinsing the inner wall of the mixing tank and the stirring rod.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Reference Figure 1-9 An external wall insulation plastering mortar and its preparation method are disclosed, comprising the following components in the indicated weight ratios:

[0036] The ingredients are: 20-45 parts silicate cement, 10-30 parts sand, 2-5 parts lime, 2-5 parts clay, 0.2-0.8 parts organic fiber, 0.7-1.5 parts gypsum, 1-3 parts adhesive powder, and a bulk density of 400-550. 3-7 parts of clay sand.

[0037] The preparation method of plastering mortar for external wall insulation includes the following steps:

[0038] Step 1: Take the materials according to the weight ratio and place the materials in the storage box on the mixing equipment;

[0039] Step Two: Staff members perform initial mixing of the raw materials located in the storage box;

[0040] Step 3: After the initial mixing, the raw materials enter the mixing equipment. The mixing equipment continuously mixes the raw materials and injects water into the mixing equipment according to the specific gravity of the raw materials, so that the water and raw materials are evenly mixed to obtain the plastering mortar for external wall insulation.

[0041] As a technical optimization of the present invention, a storage box 2 is installed on the top of the mixing tank 1. A feed hole 18 is opened at the bottom of the inner side of the storage box 2. The storage box 2 is connected to the interior of the mixing tank 1 through the feed hole 18. A fixed cylinder 8 is installed inside the mixing tank 1. Both ends of the fixed cylinder 8 penetrate the mixing tank 1. A connecting sleeve 22 is rotatably installed at one end of the fixed cylinder 8. Several water outlet holes 19 are opened on the outer wall of the fixed cylinder 8. When in use, the operator can connect the fixed cylinder 8 to the external water injection pipe through the connecting sleeve 22. Water can be injected into the interior of the mixing tank 1 through the several water outlet holes 19 on the fixed cylinder 8.

[0042] As a technical optimization of the present invention, the end of the fixed cylinder 8 away from the connecting sleeve 22 is connected to the output shaft of the motor 20 through a coupling. Both ends of the fixed cylinder 8 are equipped with mounting rings 9, which are installed on the inner wall of the mixing tank 1. Several fixing rods 21 are installed on the outer wall of the mounting rings 9. A rotating ring 10 is installed at the end of the fixing rod 21 away from the mounting ring 9. Several support plates 11 are installed on the opposite surfaces of the two rotating rings 10. When the fixed cylinder 8 rotates, the mounting rings 9 and the rotating rings 10 can better limit the position of the fixed cylinder 8, thereby improving the stability of the fixed cylinder 8 during use.

[0043] As a technical optimization of the present invention, a plurality of mounting holes 24 are provided on the side of the support plate 11. A stirring rod 12 is slidably installed in the mounting holes 24. A limiting ball 13 is installed at one end of the stirring rod 12 near the inner wall of the mixing tank 1. A spring 23 is installed on the stirring rod 12 between the support plate 11 and the limiting ball 13. When the limiting ball 13 rotates, it can push the bottom of the rotating plate 7, causing the rotating plate 7 to tilt. The raw material on the rotating plate 7 can then enter the interior of the mixing tank 1 through the feed hole 18.

[0044] As a technical optimization of the present invention, a limiting plate 14 is installed on the stirring rod 12. The limiting plate 14 and the limiting ball 13 are located on both sides of the support plate 11. In use, the spring 23 can drive the stirring rod 12 to move by pushing the limiting ball 13, while the limiting plate 14 can limit the moving distance of the stirring rod 12.

[0045] As a technical optimization of the present invention, grooves 3 are provided on both inner walls of the storage box 2, and a baffle plate 4 is installed inside the storage box 2. The two sides of the baffle plate 4 are slidably installed in the two grooves 3 respectively. One end of the baffle plate 4 penetrates through the storage box 2, and a through hole 17 is provided on the side of the baffle plate 4 away from the grooves 3. The baffle plate 4 can shield the raw materials located inside the storage box 2, providing better protection for the raw materials, and at the same time can limit the rotation angle of the rotating plate 7.

[0046] As a technical optimization of the present invention, a support rod 25 is installed on the inner wall of the feed hole 18, and a rotating plate 7 is rotatably installed on the support rod 25. Both sides of the rotating plate 7 are provided with mounting grooves 26 along the length direction. A rubber strip 27 is installed on the inner wall of the mounting groove 26. One side of the rubber strip 27 passes through the mounting groove 26. The rubber strip 27 can abut against the inner wall of the feed hole 18, thereby improving the stability of the rotating plate 7.

[0047] As a technical optimization of the present invention, the rotating plate 7 is located below the baffle plate 4, and the bottom of the inner wall on both sides of the feed hole 18 is provided with a slope. The motor 20 and the connecting sleeve 22 are respectively installed at both ends of the mixing tank 1. The slope on the feed hole 18 can make the stirring rod 12 more stable when it moves, and prevent the inner wall of the feed hole 18 from affecting the movement of the stirring rod 12.

[0048] As a technical optimization of the present invention, a discharge pipe 15 is installed at the bottom of the mixing tank 1, the top end of the discharge pipe 15 is connected to the interior of the mixing tank 1, a flow control valve 16 is installed on the discharge pipe 15, a base plate 6 is installed at both ends of the mixing tank 1, and a support frame 5 is installed at both ends of the top of the base plate 6. The top end of the support frame 5 is installed on the side of the mixing tank 1. When the plastering mortar is mixed, it can be discharged through the discharge pipe 15. When the plastering mortar is mixed, the base plate 6 and the support frame 5 can provide good support for the mixing tank 1, making the mixing tank 1 more stable during use.

[0049] In use, the operator takes the mortar mixing formula and places the mortar raw materials inside the storage box 2 for simple mixing. After the mortar raw materials are mixed, the operator installs a shielding plate 4 inside the storage box 2 to shield and protect the mortar raw materials inside. The operator connects one end of the fixed cylinder 8 to an external water injection pipe through a connecting sleeve 22, allowing water to be injected into the fixed cylinder 8 through the connecting sleeve 22. The fixed cylinder 8 stores the injected water. The operator starts the motor 20, and the output shaft of the motor 20 drives the fixed cylinder 8 to rotate. When the fixed cylinder 8 rotates, the water inside the fixed cylinder 8 flows slowly into the mixing tank 1 due to the centrifugal force and internal pressure of the fixed cylinder 8.

[0050] When the fixed cylinder 8 rotates, it can drive the mounting rings 9 at both ends to rotate. When the mounting rings 9 rotate, they can drive the rotating ring 10 to rotate through several fixed rods 21. When the rotating ring 10 rotates, it can drive several support plates 11 to rotate. The several springs 23 on the rotating plate 7 can push the limiting ball 13 to move towards the inner wall of the mixing tank 1, so that the limiting ball 13 abuts against the inner wall of the mixing tank 1 and moves on the inner wall of the mixing tank 1. When the limiting ball 13 moves, it can drive the stirring rod 12 on it to move.

[0051] When the limiting ball 13 and the stirring rod 12 move to the bottom of the storage box 2, the limiting ball 13 can move along the slope at the bottom of the inner wall of the feed hole 18 to the inside of the feed hole 18. As the stirring rod 12 and the support plate 11 move, the limiting ball 13 on the stirring rod 12 moves to the bottom side of the rotating plate 7. The spring 23 pushes the limiting ball 13 to move towards the inner top of the feed hole 18, causing the rotating plate 7 to rotate around the support rod 25. The top of the limiting ball 13 abuts against the bottom of the rotating plate 7, and the elasticity of the spring 23 pushes the rotating plate 7 to rotate. As the rotating plate 7 rotates, the raw material on the rotating plate 7 can move along the top of the rotating plate 7 to the position between the rotating plate 7 and the inner wall of the feed hole 18, and fall into the inside of the mixing tank 1 through the position between the rotating plate 7 and the inner wall of the feed hole 18. During use, the mortar raw materials can be continuously fed into the mixing tank 1 for mixing, preventing a large amount of mortar raw materials from being placed directly into the mixing tank 1. This would make it difficult for the stirring rod 12 to mix the raw materials, resulting in a longer mixing time and uneven mixing. During use, the rotation angle of the rotating plate 7 can be adjusted by adjusting the position of the limiting plate 14, thereby adjusting the feeding speed of the mortar raw materials. When the raw materials are fed into the mixing tank 1, the baffle plate 4 located on the rotating plate 7 can also push the raw materials as the rotating plate 7 rotates, making it easier for the mortar raw materials to enter the mixing tank 1.

[0052] When the stirring rod 12 and the limiting ball 13 push one side of the bottom of the rotating plate 7 via the spring 23, the limiting plate 14 located on the stirring rod 12 can limit the moving distance of the stirring rod 12 and the limiting ball 13, and at the same time adjust the rotation angle of the rotating plate 7. As the stirring rod 12 and the limiting ball 13 move, the limiting ball 13 slides along the bottom of the rotating plate 7, while the stirring rod 12 extends and retracts due to the elasticity of the spring 23. As the limiting ball 13 moves, it can push the other side of the bottom of the rotating plate 7. During use, the raw materials on the rotating plate 7 can be continuously and alternately fed into the interior of the mixing tank 1 through both sides of the rotating plate 7, so that various mortar raw materials can be more evenly sprinkled into the interior of the mixing tank 1, facilitating the mixing of the mortar raw materials by the stirring rod 12.

[0053] When moving, the limiting ball 13 can move again along the slope at the bottom of the inner wall of the feed hole 18 to the inner wall of the mixing tank 1, allowing the limiting ball 13 to move on the inner wall of the mixing tank 1. Several stirring rods 12 and support plates 11 mix the mortar raw materials that enter the mixing tank 1 through the feed hole 18. While the stirring rods 12 are mixing the raw materials, the operator can continuously inject water into the fixed cylinder 8 to pressurize the inside of the fixed cylinder 8, causing the water inside the fixed cylinder 8 to be sprayed into the mixing tank 1 through the water outlet 19, and the stirring rods 12 can then stir and mix the mortar raw materials and water.

[0054] After the mortar is mixed, the operator can open the flow control valve 16 to discharge the mortar inside the mixing tank 1 to the outside through the discharge pipe 15. After the mixing tank 1 is used up, the operator can quickly inject water into the fixed cylinder 8 through the water injection pipe. The water inside the fixed cylinder 8 is then sprayed onto the inner wall of the mixing tank 1 by the water pressure inside the fixed cylinder 8. The motor 20 drives the fixed cylinder 8 to rotate, so that the water inside the fixed cylinder 8 is evenly rinsed onto the inner wall of the mixing tank 1, the stirring rod 12, and the support plate 11 as the fixed cylinder 8 rotates. During use, there is no need for the operator to manually clean the inside of the mixing tank 1, making it more convenient to use.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
