Technical Field

[0001] The present invention relates to the technical field of concrete surface image production, and specifically to a method for producing a concrete surface image. Background Art

[0002] There are the following several methods for making patterns on the concrete surface in the market currently:

[0003] Retarding imaging technology: Printing a retarding agent onto a medium through printing technology and contacting it with the concrete. Utilizing the time difference between the setting of the retarding agent and the concrete, and flushing it with a water gun to form a concrete surface with a concave-convex pattern; Laser engraving and mechanical engraving imaging: Engraving an image with a carving knife; UV printing; Water transfer printing; Screen printing;

[0004] The above several methods have the following defects:

[0005] (1) Retarding imaging technology is affected by the time difference; it is not easy to master the time well, and the pattern is too rough;

[0006] (2) Laser engraving and mechanical engraving have a large labor intensity, low production efficiency, too large equipment investment, and serious environmental dust pollution;

[0007] (3) UV printing has a large labor intensity, large equipment investment, poor color fastness, and is not weather-resistant;

[0008] (4) Screen printing has a long plate-making cycle, complicated process, large labor intensity, and high cost. Summary of the Invention

[0009] In view of the deficiencies of the prior art, the present invention provides a method for producing a concrete surface image, which solves the problems raised in the above background art.

[0013] Step 3: Place the printing medium and the cement-inactivated special ink in a printer, and perform printing production on the mirror image;

[0014] Step 4: Place the printed medium image-side up flatly on a platform, add a mold frame, then pour special concrete, and reinforce it with a fiberglass grid or a metal mesh; After solidification, wash away the inactivated cement with a water gun to reveal the color of the underlying aggregate;

[0015] Step 5: After the surface is dry to the touch, spray a layer of fluorocarbon varnish with a thickness of 0.5 - 1 mm, and then use a flame gun to quickly heat and dry the surface in a horizontal reciprocating path to protect it.
