Description

Technical Field

[0001] The present invention relates to the field of tile adhesive production, and particularly to a processing technology and processing equipment for tile adhesives. Background Art

[0002] Tile adhesive is a polymer-modified cement-based bonding material. By adding functional additives such as latex powder and cellulose ether, the bonding strength and flexibility of traditional cement mortar are significantly improved. It has high bonding force, anti-slip property, environmental protection, and weather resistance. Due to its outstanding functionality, it also directly determines the strictness of its production process. During the production of tile adhesive, raw materials need to be accurately weighed according to the formula. The basic components include cement (grade 42.5R), aggregate (natural sand or quartz sand), redispersible latex powder, cellulose ether (such as HPMC), and functional additives (retarding agent, water retention agent, etc.). However, when using a conventional stirring device, it will adhere to the stirring roller during the stirring process of the dry raw materials, resulting in the actual weight of the stirred material being lower than the total amount of the predetermined raw materials. When the actual amount of dry raw materials is lower than the predetermined amount of dry raw materials, it will directly lead to the imbalance of the ratio of the later additives to the dry raw materials, and ultimately the quality of the finished tile adhesive fails to meet expectations. The invention patent with the Chinese patent application number 202310598902.9 provides a tile adhesive, which contains the following raw materials by weight: 50 - 60 parts of cement, 40 - 50 parts of sand, 20 - 30 parts of nano-particles, 70 - 80 parts of methyl cellulose material, 1 - 2 parts of wood cellulose, 0.05 - 1 part of other additives, and 1 - 30 parts of starch ether. By using nano-particles, it has good bonding performance. Through a special processing technology, it has great stability in various environments, forming the characteristics of strong original strength and thermal aging functionality. The deformation of this tile adhesive caused by temperature changes is much smaller than that of ordinary tile adhesives, and the fluctuation of the original strength is smaller. At the same time, after the tile deforms under external force, it can better restore its original shape through the connection of nano-particles, so it has higher fatigue resistance. In this invention, starch ether and wood cellulose are used in combination, making the performance and advantages of these two products complement each other. Therefore, the application of starch ether in tile adhesive will significantly reduce the formulation cost of tile adhesive. The technical solution proposed by the above invention mainly improves the stability of the finished tile adhesive, but its dry raw materials will also adhere to the stirring roller during the stirring process, resulting in inaccurate ratios with 20 - 30 parts of nano-particles, methyl cellulose material, wood cellulose, other additives, and starch ether in the later stage, and ultimately the functions of the finished tile adhesive fail to meet expectations. Summary of the Invention

[0003] Therefore, in view of the above problems, the present invention provides a processing technology and processing equipment for tile adhesive, which solves the technical problems that in the existing tile adhesive, due to the particularity of the dry material raw materials, it is easy to adhere to the mixing roller during the mixing process, resulting in a decrease in the total amount of dry material raw materials, and inaccurate proportioning with additives in the later stage.

[0004] To achieve the above object, the present invention adopts the following technical solutions: A processing technology for tile adhesive, comprising the following steps: S1. Raw material selection; Cement, aggregate, and functional additives are respectively selected. S2. Raw material weighing; Each raw material is weighed according to the formula ratio by an automated system, where the proportion of cement is 60%-80%, the proportion of aggregate is 15%-30%, and the proportion of functional additives is 1%-10%. S3. Mixing and stirring; The raw materials are mixed and stirred. The mixing and stirring include a dry mixing stage and a wet mixing stage. In the dry mixing stage, cement and aggregate are respectively put into a mixing blender for pre-mixing evenly. In the wet mixing stage, water and functional additives are slowly added to the pre-mixed cement and aggregate, and the rotation speed of the mixing blender and the mixing and stirring time are controlled until the slurry has no lumps, and the stirring time is 10-15 minutes. S4. Aging adjustment; The stirred slurry is allowed to stand for 10-30 minutes to promote the full hydration of the polymer. During the process of static aging of the stirred slurry, the mixing roller is lifted to make the slurry adhering to the mixing roller fall into the mixing blender. S5. Quality inspection; The bonding strength, flexural strength, setting time, and water absorption rate of the mixed slurry are tested. S6. Packaging and storage; The qualified products after quality inspection are packaged into moisture-proof sealed bags or sealed barrels.

[0005] Further, the cement is Portland cement, the aggregate includes quartz sand and fine sand, the functional additives include EVA powder, cellulose ether, retarder, and mildew preventive, and the particle size of the quartz sand and the fine sand is controlled within 0.1-0.75 mm.

[0006] A processing equipment, which is applied to the processing technology of tile adhesive, includes a mixing blender. The mixing blender includes a frame, a stirring reaction kettle fixedly arranged on the frame. The stirring reaction kettle includes a reaction kettle body and a sealing upper cover that cooperate with each other. A stirring device is integrally arranged on the sealing upper cover, and an auxiliary stirring device is arranged on the inner circumferential side surface of the reaction kettle body. The stirring device includes a rotating motor, a central support member, a stirring member, and a stirring member storage mechanism built in the central support member. The central support member is arranged along the central axis of the sealing upper cover. The central support member is driven to rotate by the rotating motor. A functional cavity is arranged inside the central support member. The stirring rod member storage mechanism is arranged in the functional cavity. The stirring rod member is rotatably connected to the stirring rod member storage mechanism. The stirring rod member includes a first stirring rod member and a second stirring rod member. The first stirring rod member is arranged around the outer circumferential side of the central support member. The first stirring rod member and the central support member are rotatably connected. The stirring rod member storage mechanism includes a central connecting rod and a first driving portion arranged on the outer circumferential side of the central connecting rod. The second stirring rod member is rotatably arranged at the bottom end of the central connecting rod. The central connecting rod can move up and down in the vertical direction. A second driving portion is arranged on the first stirring rod member. The first driving portion and the second driving portion are cooperatively connected. By driving the second driving portion through the first driving portion, the first stirring rod member is further controlled to swing in the vertical direction. During the working process, the first stirring rod member presents two states: fitting the central support member or forming a 45° angle with the central support member.

[0007] Further, when the central connecting rod extends downward, the second stirring rod member follows and extends outward; when the central connecting rod retracts upward, the second stirring rod member follows and retracts into the functional cavity.

[0008] Further, the first stirring rod member and the central support member are rotatably connected through a torsion spring. The second stirring rod member and the bottom of the central connecting rod are rotatably connected through a torsion spring.

[0009] Further, the auxiliary stirring device includes a rotating annular groove and a rotating ring embedded in the rotating annular groove. Under the action of an external force, the rotating ring freely rotates in the rotating annular groove. The surface of the rotating ring is a metal surface that can be magnetically attracted. A magnet is arranged at the end of the free end of the second stirring rod member. When the second stirring rod member extends outward, it deflects under the action of the torsion spring and is magnetically connected to the rotating ring.

[0010] Further, both the first driving portion and the second driving portion are rack structures.

[0011] Further, both the first stirring rod member and the second stirring rod member are cylindrical rod members.

[0012] By adopting the foregoing technical solutions, the beneficial effects of the present invention are: 1. Through structural improvements and innovative improvements to the processing technology, the present invention avoids the problem that during the production and preparation of tile adhesive, especially in the stirring process, the colloid adheres to the stirring equipment, resulting in the finished product discharge volume being lower than the actual discharge volume. This, in turn, leads to a mismatch in the ratio with later additives and a decline in the quality level of the finished tile adhesive. Specifically: The present invention innovates in the curing adjustment of step S4 in the processing technology. In the traditional processing technology, the action of lifting the stirring equipment is also carried out in this step. However, because the stirring equipment in the traditional processing technology uses a conventional stirring equipment with a conventional stirring roller, the problem of the stirring material adhering to the stirring roller occurs during the lifting process, affecting the subsequent additive ratio. The present invention, through the improvement of the processing equipment and in coordination with the step of lifting the stirring equipment, can ensure that the stirring material basically completely falls into the material cylinder, without having too much impact on the later ratio, thereby improving the quality of the finished product. Specifically: In the processing equipment proposed by the present invention, its main difference from the existing stirring equipment lies in that it includes two stirring mechanisms. During the working process, the two stirring mechanisms can cooperate with each other and can avoid the stirring mixture adhering to the stirring roller to the greatest extent after stirring, which affects the quality of the later finished product. Among them, the two stirring mechanisms are arranged vertically up and down, with a height difference between them, so that a comprehensive and complete stirring operation can be carried out on the materials in the stirring reaction kettle.

[0013] 2. The stirring device and the auxiliary stirring device in the present invention work synchronously during operation, that is, they do not work independently but have a cooperative working connection. When the stirring work is not carried out, the contact surfaces of the stirring device and the stirred material are extremely small, which can ensure that the stirring device is in a vertical state and is convenient for separation from the material when lifted. The stirring device is linked in structure and operation through the stirring rod storage mechanism. The structures responsible for the stirring operation are the first stirring rod and the second stirring rod. Through the stirring rod storage mechanism, the first stirring rod and the second stirring rod can be simultaneously stored after the stirring is completed. Specifically: The first stirring rod is rotatably connected to the central support rod and is also rotatably connected to the central connecting rod. The connection method between the two is a gear meshing connection using the first driving part and the second driving part. Along with the up and down movement of the central connecting rod, it will drive the first driving part to move up and down, thereby changing the meshing relationship between the first driving part and the second driving part. Then the first stirring rod will deflect along with the up and down movement of the central connecting rod, approaching or moving away from the central support rod. The second stirring rod is arranged at the bottom of the central connecting rod and is rotatably connected to the central connecting rod through a torsion spring. When it is not affected by external forces, it will extend outward under the action of the torsion spring to form a certain angle with the central support rod. At this time, the stirring operation is carried out. When the stirring operation is completed and it needs to be withdrawn, the second stirring rod will rise with the central connecting rod. When it touches the edge of the central support rod, it will be forced by the edge to retract inward and be stored in the functional cavity. During this process, the material adhered to the second stirring rod will be stored in the functional cavity along with the second stirring rod and will be scraped off and dropped by the edge of the central support rod at the same time.

[0014] 3. In the present invention, when the second stirring rod extends outward and deflects, it can cooperate with the auxiliary stirring device. The principle is that a magnet is provided at the end of the free end of the second stirring rod. After the magnet deflects with the second stirring rod, it is magnetically attracted to the rotating ring. At this time, both ends of the second stirring rod have supports, ensuring its stability during the stirring operation.

[0015] 4. The first stirring rod and the second stirring rod in the present invention are both cylindrical rods. On the one hand, it reduces the resistance during the stirring process, and on the other hand, it can minimize the adhesion of materials during the storage process to the greatest extent.
