Preparation process of multicolor epoxy terrazzo floor

[0026] Example 1:

[0027] refer to Figure 1-2 , a multi-color epoxy grinding stone floor preparation process, comprising the following steps:

[0028] s1, fully mixing the first millstone slurry and the first color paste to obtain product A, and fully mixing the second millstone slurry and the second color paste to obtain product B;

[0029] s2, simply mixing product A and product B to obtain product C;

[0030] s3, product C is sieved through the screen to obtain product D;

[0031] s4. Spread the product D on the ground, scrape it flat and pat it tightly;

[0032] s5. After the product D is cured, rough grinding, fine grinding and overcoating are performed.

[0033] In this process, firstly, uniformly mixed product A and product B are prepared. Since product A is obtained by fully mixing the first millstone slurry and the first color paste, the final slurry of product A is pure color. Similarly, the final slurry of product B is The color of the product is also a solid color, and the product A and the product B are simply mixed roughly, so that the color of the product A and the color of the product B are intertwined without being merged into a solid color, and then sieved, and the sieving step is also It belongs to a mixing process. The characteristic of this kind of mixing is that the product C is not mixed in a small range, and the hole of the screen is used as the minimum mixing unit. The part passing through the hole 10 will not be mixed, and the part passing through the mesh body 9 will form. The blocking of the product C produces a small range of mixing. After the product D is laid, the ground is leveled by a leveling thing. The leveling thing can be leveled with a long bar, and then beat by a vibrating device after leveling. , to make the ground dense, this step cannot be polished by a polisher. If a polisher is used for polishing, the color of the ground will be very chaotic, and the color of the ground will be pasted. After the product D is cured, the color of the ground is basically fixed, and then Follow-up processing steps can be performed, and the grindstone floor produced by this process is a multi-color epoxy grindstone floor, with uniform color spots, good ground integrity, and beautiful and comfortable colors.

[0034] Embodiment 2:

[0035] refer to Figure 1-3 , a multi-color epoxy grinding stone floor preparation process, comprising the following steps:

[0036] s1. Fully mixing the first millstone slurry and the first color paste to obtain a product A, and fully mixing the second millstone slurry and the second color paste to obtain a product B, the product A includes: accounting for 20-25% Specification 4 -6-mesh white glass, 3-5% specification 6-8 mesh white glass, 10-15% specification 10-20 mesh white glass, 0.7-1% specification 6-8 mesh lens, 3 -5% specification 16-30 mesh lens, 15-20% specification 7-140 mesh quartz sand, 25-35% specification 325 mesh quartz powder, 9-10% resin, 0.17-0.18 % white paste, 0.001% carbon black paste, 0.0014% medium yellow paste, the above ratios are weight ratios; product B includes: 15-18% specification 6-8 mesh white glass, 12-15% specification 10-20 mesh white glass, 1.3-1.5% specification 6-8 mesh gray background lens, 3-4% specification 16-30 mesh gray background lens, 22-25% specification 70 -120 mesh quartz sand, 28-31% specification 325 mesh quartz powder, 10-12% resin, 0.02-0.03% carbon black paste, 0.0114% medium yellow paste, 0.0071 % of bright red pulp, the above proportions are by weight;

[0037] Wherein the preferred batching ratio of product A, product B is as follows:

[0038]

[0039] s2, simply mixing product A and product B to obtain product C;

[0040] s3, sieving product C through a screen to obtain product D, wherein the screen is a circular sieve with a diameter of 10mm; or the screen is a rectangular screen with a length and width of 10mm;

[0041] s4. Spread the product D on the ground, and slap and compact it after scraping it. After the product D is spread on the ground, it is leveled by a long bar, and then the ground is tapped and compacted by a vibration device installed with a flat plate;

[0042] s5. After the product D is solidified, rough grinding is performed. After rough grinding, the surface is cleaned up, and slurry sealing, fine grinding, and surface treatment are performed. The slurry material is: gold grinding stone G500 system resin and 325 mesh quartz powder. The mixture, wherein the added amount of 325-mesh quartz powder is 60% of the resin content, and the slurry-replenishing material in this mixing ratio is a paste, which is easy to scrape.

[0043] As an embodiment, steps s2 and s3 are completed by a mixing and sieving device, refer to image 3 , the mixing and screening device includes a mixing box 5, at least two raw material boxes 4 are connected and installed on the top of the mixing box 5, a feeding cylinder 8 is connected and installed under the mixing box 5, and a screw rod 6 is rotatably connected in the mixing box 5, A screw blade 2 is rotatably connected in the feeding cylinder 8, the screw blade 2 is drivingly connected with the screw rod 6, the screw rod 6 is drivingly connected with a rotating motor 3, the rotating motor 3 is fixedly installed with the mixing box 5, and the bottom end of the feeding cylinder 8 is open. A screen 1 is fixedly installed at the bottom opening of the feeding cylinder 8; a number of wheels 7 are installed on the mixing box 5; 8 is a straight cylinder structure; a blanking speed adjustment valve is provided between the raw material box 4 and the mixing box 5, and the blanking speed of the raw materials in the raw material box 4 into the mixing box 5 is adjusted through the blanking speed adjustment valve. The material speed adjustment valve changes the mixing ratio of product A and product B, and realizes the change of the size of different color spots on the ground. The size of the channel between it and the mixing box 5.

[0044]The uniformly mixed product A and product B are loaded into different raw material boxes 4, and the product A and product B enter the mixing box 5. The rotation of the screw rod 6 makes the materials in the mixing box 5 carry out preliminary mixing. The raw material is pushed down by the screw blade 2, so that the coarsely mixed material is extruded from the holes of the screen 1, and the mixing step of the material taking the screen hole as the minimum mixing unit is realized, and the whole device is driven to move, and the preliminary product D is completed. Pave, then scrape it with a long bar, and finally beat it with a vibrating motor to make the ground densely laid, and wait for the subsequent steps of rough grinding and fine grinding after curing;

[0045] As an embodiment, several inclined plates are fixedly installed on the screw rod 6 to increase the stirring strength of the screw rod 6 .
