Description

Technical Field

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

[0002] Tile adhesive is a polymer-modified cement-based adhesive 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 adhesion, anti-slip properties, 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, the raw materials must be accurately weighed according to the formula. The basic components include cement (42.5R grade), aggregate (natural sand or quartz sand), redispersible latex powder, cellulose ether (such as HPMC) and functional additives (retarders, water retention agents, etc.). When using conventional mixing devices, the raw materials will adhere to the mixing roller during the mixing process of dry materials, which will cause the actual weight of the mixed material to be lower than the predetermined total amount of raw materials. When the actual amount of dry materials is lower than the predetermined amount of dry materials, it will directly lead to an imbalance in the content of later additives and the ratio of dry materials, which ultimately leads to the quality of the finished tile adhesive not meeting expectations.

[0003] Chinese patent application number 202310598902.9 discloses a tile adhesive comprising the following ingredients, by weight: 50-60 parts cement, 40-50 parts sand, 20-30 parts nanoparticles, 70-80 parts methylcellulose, 1-2 parts lignocellulose, 0.05-1 part other additives, and 1-30 parts starch ether. The nanoparticles exhibit excellent bonding properties and, through a specialized processing technique, possess exceptional stability under various conditions, resulting in strong original strength and thermal aging resistance. This tile adhesive exhibits significantly less deformation with temperature changes than other tile adhesives and exhibits less fluctuation in original strength. Furthermore, after deformation by external forces, the nanoparticles' bonding properties allow the tile to recover its original shape, resulting in higher fatigue resistance. The combination of starch ether and lignocellulose in this invention synergizes the performance and advantages of these two products, significantly reducing the cost of the tile adhesive formulation. The technical solution proposed in the above invention mainly improves the stability of the finished tile adhesive. However, its dry raw materials will also stick to the stirring roller during the stirring process, resulting in inaccurate ratios with 20-30 parts of nanoparticles, methyl cellulose materials, wood cellulose, other additives and starch ether in the later stage, ultimately resulting in the finished tile adhesive functioning less than expected. Summary of the Invention

[0004] Therefore, in response to the above problems, the present invention proposes a processing technology and processing equipment for tile adhesive, which solves the technical problem that due to the particularity of the dry raw materials, the existing tile adhesive is prone to adhesion to the stirring roller during the mixing and stirring process, thereby resulting in a decrease in the total amount of dry raw materials and inaccurate ratio with additives in the later stage.

[0005] To achieve the above object, the present invention adopts the following technical solution: a processing technology for tile adhesive, comprising the following steps:

[0006] S1. Raw material selection: select cement, aggregate, and functional additives respectively;

[0007] S2. Raw material weighing: The raw materials are weighed according to the formula ratio through an automated system, of which cement accounts for 60%-80%, aggregate accounts for 15%-30%, and functional additives account for 1%-10%;

[0008] S3, mixing and stirring; the raw materials are mixed and stirred, and the mixing and stirring includes a dry mixing stage and a wet mixing stage. The dry mixing stage is to put the cement and aggregate into the mixing mixer respectively for premixing. The wet mixing stage is to slowly add water and functional additives to the premixed cement and aggregate. The speed of the mixing mixer and the mixing time are controlled until the slurry is free of lumps. The stirring time is 10-15 minutes;

[0009] S4, aging adjustment; the stirred slurry is allowed to stand for 10-30 minutes to promote full hydration of the polymer, and the stirred slurry is allowed to stand and mature during the process of lifting the stirring roller so that the slurry adhering to the stirring roller falls into the mixing mixer;

[0010] S5. Quality inspection: test the bonding strength, flexural strength, setting time and water absorption of the mixed slurry;

[0011] S6. Packaging and storage: After completing quality inspection, qualified products are packaged into moisture-proof sealed bags or sealed barrels.

[0012] Furthermore, the cement is silicate cement, the aggregate includes quartz sand and fine sand, the functional additives include EVA rubber powder, cellulose ether, retarder and mildew inhibitor, and the particle size of the quartz sand and the fine sand is controlled to be 0.1-0.75 mm.

[0013] A processing device, used in the processing of tile adhesive, includes a mixing mixer, the mixing mixer comprising a frame and a stirring reactor fixedly mounted on the frame, the stirring reactor comprising a reactor body and a sealed upper cover that cooperate with each other, a stirring device integrated on the sealed upper cover, an auxiliary stirring device provided on the inner circumferential side of the reactor body, the stirring device comprising a rotating motor, a central support rod, a stirring rod, and a stirring rod storage mechanism built into the central support rod;

[0014] The central support rod is arranged along the central axis of the sealing upper cover, and the central support rod is driven to rotate by the rotary motor. A functional cavity is provided in the central support rod, and the stirring rod storage mechanism is provided in the functional cavity. The stirring rod is rotatably connected to the stirring rod storage mechanism. The stirring rod includes a first stirring rod and a second stirring rod. The first stirring rod is arranged around the outer circumferential side of the central support rod, and the first stirring rod and the central support rod are rotatably connected. The stirring rod storage mechanism includes a central connecting rod, a first driving portion provided on the outer circumferential side of the central connecting rod, and the second stirring rod is rotatably provided at the bottom end of the central connecting rod. The central connecting rod can be raised and lowered in the vertical direction. The first stirring rod is provided with a second driving portion. The first driving portion and the second driving portion are cooperatively connected to each other. The first driving portion drives the second driving portion, thereby controlling the first stirring rod to swing in the vertical direction. During operation, the first stirring rod is in two states: in contact with the central support rod or at an angle of 45° to the central support rod.

[0015] Furthermore, when the central connecting rod extends downward, the second stirring rod follows and extends outward; when the central connecting rod retracts upward, the second stirring rod follows and retracts into the functional cavity.

[0016] Furthermore, the first stirring rod is rotatably connected to the central supporting rod via a torsion spring, and the second stirring rod is rotatably connected to the bottom of the central connecting rod via a torsion spring.

[0017] Furthermore, the auxiliary stirring device includes a rotating annular groove and a rotating ring embedded in the rotating annular groove. Under the action of external force, the rotating ring rotates freely in the rotating annular groove. The surface of the rotating ring is a metal surface that can be magnetically attracted. A magnet is provided at the free end of the second stirring rod. When the second stirring rod extends outward, it is deflected under the action of the torsion spring and is magnetically connected to the rotating ring.

[0018] Furthermore, both the first driving part and the second driving part are rack structures.

[0019] Furthermore, the first stirring rod and the second stirring rod are both cylindrical rods.

[0020] By adopting the above technical solution, the beneficial effects of the present invention are:

[0021] 1. The present invention avoids the problem that the colloid adheres to the stirring equipment during the production and preparation of tile adhesive, especially during the stirring process, resulting in the finished product output being lower than the actual output, and further causing the ratio with the subsequent additives to be unbalanced, thereby reducing the quality level of the finished tile adhesive. Specifically, the present invention innovates the process during the aging adjustment of step S4 in the processing technology. In the traditional processing technology, the stirring device is also lifted in this step. However, because the stirring device in the traditional processing technology uses a conventional stirring device and its stirring roller is a conventional stirring roller, the stirring material will stick to the stirring roller during the lifting process, affecting the quality of the finished tile adhesive. The subsequent additive ratio, and the present invention, through the improvement of the processing equipment, matches the steps mentioned above in the stirring equipment, can ensure that the stirring material basically falls into the barrel completely, will not cause too much impact on the later ratio, thereby improving the quality of the finished product. Specifically: the processing equipment proposed in the present invention is different from the existing stirring equipment mainly in that it contains two stirring mechanisms. During the working process, the two sets of stirring mechanisms can work together and can avoid the stirred mixture from sticking to the stirring roller to the greatest extent after the stirring is completed, affecting the quality of the later finished product. The two sets of stirring mechanisms are arranged up and down in the vertical direction, and there is a height difference between the two, so that the materials in the stirred reactor can be fully and completely stirred.

[0022] 2. The stirring device and the auxiliary stirring device in the present invention work synchronously during operation, that is, the two do not work independently, but are in a mutually coordinated working relationship. When the stirring work is not performed, the contact surface between the stirring device and the stirring material is 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 a stirring rod storage mechanism, wherein the structures responsible for the stirring operation are the first stirring rod and the second stirring rod, and the stirring rod storage mechanism can simultaneously store the first stirring rod and the second stirring rod after the stirring is completed, specifically: the first stirring rod is rotatably connected to the central support rod, and it is also rotatably connected to the central connecting rod, and the two are connected by adopting a gear meshing connection of the first driving part and the second driving part, and as the central connecting rod rises and falls, it drives the first driving part The up and down lifting and lowering change the meshing relationship between the first driving part and the second driving part, and the first stirring rod will be deflected as the central connecting rod rises and falls, approaching the central support rod or moving away from the central support rod, and 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 force, it will extend outward under the action of the torsion spring to form a certain angle with the central support rod, and stirring operation is performed at this time. When the stirring operation is completed and it needs to be pulled out, the second stirring rod will rise upward with the central connecting rod, and when it contacts the end edge of the central support rod, it will be retracted inward by the external force of the end edge and stored in the functional cavity. In this process, the material stuck to the second stirring rod will be stored in the functional cavity as the second stirring rod is stored in the functional cavity and at the same time be pulled down and dripped by the end edge of the central support rod.

[0023] 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 free end of the second stirring rod. The magnet is magnetically connected to the rotating ring after the second stirring rod is deflected. At this time, both ends of the second stirring rod are supported, ensuring that it is more stable during the stirring operation.

[0024] 4. The first stirring rod and the second stirring rod in the present invention are both cylindrical rods, which can reduce the resistance during the stirring process on the one hand, and can minimize the adhesion of materials during the storage process on the other hand.
