Description

Technical Field

[0001] The present invention relates to the technical field of 3D printing, and in particular to a stone-like coating for replicating cultural relics formed by 3D printing and a preparation method thereof. Background Art

[0002] In recent years, due to the impact of climate and the environment, some ancient relics such as Buddha statues and Buddhist caves have suffered severe damage. Imitation preservation, as an important means of protection, uses original or proportional imitations. However, traditional imitations of Buddha statues and Buddhist caves are mostly handmade, with long production cycles, limited skills, and limited materials. This also prevents mass production. With the development of 3D printing technology, binder jet 3D printing technology has enabled mass production of replicas of ancient relics such as Buddha statues and Buddhist caves. The printed replicas are more refined and lightweight, gaining recognition within the industry. However, because the sand particles used in binder jet 3D printing are relatively small, the surface of the printed replicas is relatively smooth, failing to achieve the desired stone-like texture required of the surface of the replicas. Summary of the Invention

[0003] Based on this, it is necessary to address the problem that the surface of antique cultural relics produced by 3D printing technology in the existing technology is smooth and cannot meet the requirements of the texture of stone particles on the surface of antique cultural relics. Based on this, the present invention provides an imitation stone soil paint, which is sprayed onto the surface of 3D printed antique cultural relics to increase the roughness of the surface of the antique cultural relics and restore the texture of the stone particles on the surface of the antique cultural relics.

[0004] A stone-soil imitation paint, comprising 60-70 parts by weight of a base material and 30-40 parts by weight of a binder;

[0005] The binder includes solvent A and solvent B;

[0006] The solvent A is one or more of a single-component polyurethane resin, epoxy resin, polyester resin, silicone resin, and vinyl ester resin;

[0007] The solvent B is one or more of styrene acrylic emulsion, acrylic emulsion, silicone acrylic emulsion, Gushabao, and 855 anti-alkali emulsion.

[0008] Furthermore, the base material is quartz sand.

[0009] Furthermore, the mesh size of the quartz sand is 100-200 meshes.

[0010] Furthermore, the porosity of the quartz sand is 35%-40%.

[0011] Furthermore, the quartz sand is at least one of silica sand or ceramsite sand.

[0012] Furthermore, the weight ratio of the solvent A to the solvent B is 1:1.

[0013] Furthermore, the solvent A is epoxy resin, and the solvent B is styrene acrylic emulsion.

[0014] A method for preparing a stone-soil-like coating, comprising the following steps:

[0015] S1, weighing a certain amount of solvent A and solvent B in a weight ratio of 1:1, pouring them into a stirring bucket in sequence, and stirring for 3-5 minutes to obtain a binder mixture;

[0016] S2, slowly adding the base material into the stirring barrel several times, stirring for 5-10 minutes, to obtain the stone-like coating.

[0017] Furthermore, the ratio of the binder mixture to the base material is 1.5-3:1.

[0018] A 3D printed product, the surface of which is sprayed with the imitation stone soil coating according to any one of claims 1 to 7.

[0019] The present invention provides a stone-and-soil-like coating in which a quartz sand base material is evenly dispersed in the coating to enhance dispersion. Solvent A is highly miscible with the base quartz sand and exhibits advantages such as high viscosity, low shrinkage, and mildew resistance. Solvent B is also highly miscible with the base quartz sand and exhibits excellent weather resistance, mildew resistance, moisture resistance, and pollution resistance. Evenly spraying the coating onto the surface of a 3D-printed antique artifact can increase the roughness of the artifact's surface and restore the desired texture of the artifact's stone particles. The coating also exhibits strong adhesion, is easily applied to surfaces with heterogeneous structures, does not flow, cures quickly, and exhibits low shrinkage. DETAILED DESCRIPTION

[0035] The solvent A is one or more of a single-component polyurethane resin, epoxy resin, polyester resin, silicone resin, and vinyl resin, and does not require a curing agent;

[0036] The solvent B is one or more of styrene acrylic emulsion, acrylic emulsion, silicone acrylic emulsion, Gushabao, and 885 anti-alkali emulsion.

[0037] In this embodiment, the base material is quartz sand, which is spherical and has a porosity of about 35%-40%, forming an infiltration space for solvent A and solvent B, thereby improving the bonding and mechanical properties of the imitation stone soil coating.

[0038] Preferably, the solvent A is an epoxy resin, which has excellent miscibility with the base material and offers advantages such as excellent mechanical properties, high viscosity, low shrinkage, low cost, and mildew resistance. Furthermore, the inherent polar hydroxyl groups and ether bonds in the epoxy resin molecular chain provide excellent adhesion to quartz sand and antique artifact surfaces. Furthermore, the epoxy resin exhibits low shrinkage during curing, generating minimal internal stress, further enhancing viscosity and strength.

[0039] Preferably, the solvent B is a styrene acrylic emulsion, which has excellent miscibility with the base material and also has the advantages of excellent weather resistance, mildew resistance, moisture resistance, and pollution resistance.

[0040] In another embodiment, the mesh size of the quartz sand is 100-200. By selecting quartz sand of a specific mesh size, the imitation stone soil paint applied to the surface of the antique artifact has a certain roughness, that is, a granular texture, achieving a simulation effect.

[0045] S2, slowly adding the base material into the stirring barrel several times, stirring for 5-10 minutes, to obtain the stone-like coating.

[0046] The mixing ratio of the adhesive mixture to the base material is 1.5-3:1.

[0047] Preferably, in step S1, a certain amount of epoxy resin and styrene acrylic emulsion are weighed in a ratio of 1:1, poured into a stirring bucket in sequence, and stirred at a constant speed for 3-5 minutes to obtain a binder mixture;

[0048] In step S2, a certain mass of 100-140 mesh quartz sand is slowly added to the mixing barrel several times, the ratio (weight ratio) of the binder mixture to the quartz sand is controlled to be 1.5:1, and the mixture is stirred for 5-10 minutes to obtain the imitation stone soil coating.

[0049] In another embodiment, a process for preparing an antique artifact includes the following steps:

[0050] Step 1, data extraction: stick points on the surface of ancient relics such as Buddha heads, cultural relics wheels, and Buddha statues, read the structural features of the ancient relics through 3D scanning equipment, and obtain the scanning data of the ancient relics.

[0051] Step 2, data processing: perform three-dimensional data modeling on the scanned data to form a three-dimensional digital model file of the ancient monuments and cultural relics.

[0052] Step 3: Convert the three-dimensional digital model file into a digital model using different software to obtain a three-dimensional digital model of the ancient monument.

[0053] Step 4: 3D printing. The three-dimensional digital model is imported into a 3D printer for printing to obtain a 3D printed product of an antique cultural relic.

[0054] Step 5: performing surface cleaning, hardening, and strengthening processes on the 3D printed product to obtain a 3D printed product blank.

[0055] Step 6: Hardening treatment: applying high-strength resin on the surface of the 3D printed product blank to harden the 3D printed product blank.

[0056] Step 7, spraying treatment: spraying the imitation stone soil coating as described in the above embodiment on the hardened 3D printed product blank to obtain an imitation antique cultural relic.

[0057] In this embodiment, the antique cultural relics formed by 3D printing have the advantages of refinement and lightweight, and can be mass-produced. Imitation stone and soil paint is sprayed on the surface of the printed blank to increase the roughness of the surface of the antique cultural relics and restore the granular texture of the antique cultural relics.
