Technical Field

[0001] The present invention relates to the technical field of 3D printing methods, and in particular to a weather-resistant process method for printing products. Background Art

[0002] Large and medium-sized outdoor urban sculptures mostly use stainless steel, fiberglass and stone carving techniques. Stainless steel outdoor sculptures have complex production processes, high production costs, and long production cycles. Although fiberglass sculptures have lower production costs, they have poor outdoor durability, such as cracking, peeling, and weathering. Stone sculptures also have weathering and easy decay problems, which cannot meet the durability requirements of contemporary people for outdoor sculptures. The innovation of outdoor sculpture production technology makes it weather-resistant, making 3DP molding technology the new favorite of outdoor sculptures. Whether from the perspective of visual appreciation or outdoor durability, 3DP outdoor sculpture products bring people a brand-new experience.

[0003] The production process of 3DP outdoor urban sculptures has begun to be standardized. Although the printing and curing processes have been solved, the post-processing process is still insufficient. The weather resistance process is lacking, resulting in defects such as peeling and cracking on the surface of outdoor sculpture products; especially water-related sculptures are more serious, with obvious weather resistance defects, and cannot be stabilized for application, limiting the development of 3DP outdoor sculptures. Summary of the invention

[0004] Based on this, it is necessary to provide a weather resistance process method for printing products to address the problem of poor weather resistance of current 3DP printed products.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0011] After the seam treatment is completed, the surface of the printed product is scraped and polished;

[0012] Apply the coating to the surface coating layer of the printed product after polishing.

[0013] In one embodiment, the printed product is composed of a plurality of single modules, and each single module is connected and then subjected to seam treatment.

[0014] In one embodiment, the seam processing includes:

[0015] A second groove is provided on the outer surface where the connection gap between two adjacent monomer modules is located;

[0016] Spraying an anti-penetration coating on the second groove to form a waterproof layer;

[0017] Spraying an adhesion promoter on the dried waterproof layer on the surface of the second groove;

[0018] Insert the tendon material into the second groove of the sculpture and fill it with adhesive;

[0019] After the joint treatment is completed, the surface is scraped and polished.

[0020] In one embodiment, the shape of the lattice structure includes a rectangle or a triangle.

[0021] In one embodiment, the opening of the first groove gradually increases in the direction from the bottom surface to the top surface.

[0022] In one embodiment, spraying an anti-penetration agent coating on the surface of the printed product to form a waterproof layer includes: spraying a water-repellent anti-penetration agent coating on the surface of the printed product, spraying 2 to 3 times, and drying for 30 minutes.

At the same time, these grooves also provide an ideal position for the subsequent embedding of the reinforcement material, further improving the overall strength and durability of the product. Secondly, the anti-penetration agent coating is sprayed to form a waterproof layer, which effectively prevents the penetration of moisture and other harmful substances, protects the interior of the product from damage, extends the service life of the product, and improves the corrosion resistance of the product.

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] none DETAILED DESCRIPTION

[0029] The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0030] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be a centered element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a centered element at the same time. The terms "vertical", "horizontal", "left", "right", "top", "bottom", "bottom end", "top end" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] The embodiment of the present invention discloses a weather resistance process method for printing products, and the disclosed weather resistance process method specifically includes the following steps:

[0033] A plurality of first grooves are formed on the surface of the printed product, and the plurality of first grooves form a grid structure with intervals; specifically, firstly, a plurality of first grooves are precisely formed on the surface of the printed product, and the grooves are distributed at certain intervals to form a dense grid structure. This step is intended to provide a physical basis for subsequent material embedding and enhancing adhesion, and also increases the surface roughness, which is conducive to the adhesion of the waterproof layer and other coatings.

[0034] The anti-penetration coating is sprayed on the surface of the printed product to form a waterproof layer; specifically, the anti-penetration coating is then evenly sprayed on the surface of the printed product to form a dense waterproof layer. The waterproof layer can effectively prevent moisture from penetrating into the product, protect the substrate from water erosion, and thus extend the service life of the product.

[0035] Spray the adhesion promoter on the waterproof layer on the surface of the dried printed product; after the waterproof layer is completely dry, spray the adhesion promoter on it. This promoter can significantly improve the adhesion between the waterproof layer and the subsequent coating or embedded material, ensuring the stability of the entire surface treatment structure.

[0036] The ribs are embedded into the first groove of the sculpture and filled with adhesive; the special ribs (such as metal wires, glass fiber strips, etc.) are embedded into the previously opened grid-shaped grooves one by one and filled with high-strength adhesive. These ribs not only enhance the overall structural strength of the printed product, but also improve its wind pressure resistance and deformation resistance.

[0037] After the seam treatment is completed, the surface of the printed product is scraped and polished; after embedding and filling, the surface of the printed product is carefully treated with seams to ensure that all gaps are properly sealed. Subsequently, the entire surface is scraped and polished to remove excess material and level the surface, creating good conditions for subsequent coating construction.

[0038] Apply coating on the surface coating of the printed product after polishing. Finally, apply different functional coatings (such as UV-resistant and weather-resistant coatings) on the surface coating of the printed product after polishing according to specific needs. This step further improves the weather resistance of the product and can give the product a specific appearance according to customer requirements.

[0039] In the weather-resistant process method disclosed in the embodiment of the present invention, by opening a plurality of first grooves of a grid structure with intervals and distributions on the surface of the printed product, the stability and bearing capacity of the product structure are effectively enhanced. At the same time, these grooves also provide an ideal position for the subsequent embedding of the reinforcement material, further improving the overall strength and durability of the product. Secondly, the anti-penetration agent coating is sprayed to form a waterproof layer, which effectively prevents the penetration of moisture and other harmful substances, protects the interior of the product from damage, extends the service life of the product, and improves the corrosion resistance of the product. Next, an adhesion promoter is sprayed on the waterproof layer to provide a more solid adhesion foundation for subsequent coatings and treatment layers, ensuring the stability and durability of subsequent treatments. Embedding the reinforcement material into the first groove and filling it with an adhesive not only enhances the structural strength of the product, but also makes the joints smoother and more beautiful, reducing appearance defects caused by improper joint treatment.

[0040] In the embodiments disclosed in the present invention, the printed product is composed of a plurality of monomer modules, and each monomer module can be connected to a joint treatment, which effectively solves the weather resistance and structural strength problems existing at the joints of the printed product composed of a plurality of monomer modules. This process not only improves the sealing and stability of the joints, but also enhances the overall wind pressure resistance and deformation resistance of the product. At the same time, the implementation of the present invention also has the advantages of simple operation, low cost, and significant effect, and is suitable for the production and application fields of various modular printed products.

[0041] Furthermore, the seam processing may include:

[0042] A second groove is provided on the outer surface where the connection gap between two adjacent monomer modules is located; first, a precise groove is made on the outer surface where the connection gap between two adjacent monomer modules is located. This step aims to provide the necessary space and structural basis for subsequent waterproofing, material embedding and filling by opening the second groove. The depth, width and shape of the groove need to be designed according to specific product requirements and material properties to ensure the best treatment effect.

[0043] Spray the second groove with an anti-penetration agent to form a waterproof layer. The paint should have good weather resistance, water resistance and chemical stability to ensure effective waterproofing in harsh environments. The thickness and uniformity of the paint should be controlled during the spraying process to avoid bubbles or missing paint. After the paint dries naturally, a dense waterproof layer will be formed to effectively block water penetration.

[0044] Spray an adhesion promoter on the dried waterproof layer on the surface of the second groove; spray an adhesion promoter on the dried waterproof layer on the surface of the second groove. The purpose of this step is to improve the adhesion between the waterproof layer and the subsequent embedded material to ensure the stability and durability of the filling process. The adhesion promoter should have good permeability and adhesion, and be able to penetrate into the surface of the waterproof layer and tightly bond with it.

[0045] The reinforcement material is embedded in the second groove of the sculpture and filled with adhesive; the pre-prepared reinforcement material (such as metal wire, fiberglass strips, etc.) is embedded in the processed second groove. These reinforcement materials not only increase the structural strength of the joints, but also improve the overall rigidity and deformation resistance of the product. Subsequently, the groove is filled with a high-strength adhesive to ensure that the reinforcement material is firmly fixed in place and fill all possible gaps and cracks. The choice of adhesive should take into account its weather resistance, bond strength, and compatibility with waterproof layers and adhesion promoters.

[0046] After the seam treatment is completed, the surface is scraped and polished. After the seam treatment is completed, the entire surface is carefully scraped and polished. This step is to eliminate the bulges, depressions or unevenness that may occur during the filling process, so that the seam is highly consistent and smooth with the surrounding surface. At the same time, scraping and polishing can further remove excess adhesive and adhesion promoter residues to ensure the neatness and beauty of the product surface. Through fine polishing, a seamless, flat and smooth printed product surface is finally presented.

[0047] In an optional embodiment, the shape of the lattice structure may include a rectangle or a triangle. In this case, the rectangular lattice structure can provide uniform and stable support due to its regular geometric shape, thereby enhancing the overall structural strength of the printed product. At the same time, the rectangular lattice structure is also convenient for construction and filling materials, thereby improving production efficiency and product quality. On the other hand, the triangular lattice structure is known for its excellent stability, and can effectively disperse external forces in multiple directions, further enhancing the deformation resistance and weather resistance of the printed product. Whether it is a rectangular or triangular lattice structure, it can significantly improve the mechanical properties of the printed product, extend its service life, and meet a variety of application requirements. Of course, there may be other shapes, which are not limited by the embodiments of the present invention.

[0048] In further optimizing the embodiment of the present invention, the interior of the second groove can be innovatively provided with small protrusions (or texture structures). The provision of these small protrusions is mainly based on the following considerations and effects: the presence of the small protrusions can increase the contact area between the inner surface of the second groove and the subsequent filling material (such as adhesive, tendon material, etc.), thereby enhancing the mechanical bite force and adhesion between them. This physical locking mechanism helps to improve the stability and durability of the bonding and prevent the material from falling off or shifting during long-term use.

[0049] The small bumps not only enhance the bonding effect, but also improve the overall structural strength of the printed product joints to a certain extent. As additional support points, they can withstand more external stress and impact, making the printed product more durable.

[0050] Optionally, the opening of the first groove in the direction from the bottom surface to the top surface can be gradually enlarged. This inverted trapezoidal design provides a gradually transitioning contact surface for the embedded material (such as tendon material, filler, etc.). This gradual contact method helps the material to better fit the wall of the groove, thereby enhancing the adhesion effect and preventing the material from falling off or shifting when subjected to external force. Because the inverted trapezoidal design gradually constrains the material more tightly during the embedding process, it can significantly improve the structural stability of the joint. This stability comes not only from the physical fit between the material itself and the wall of the groove, but also from the mechanical support provided by the gradually unfolding shape of the material in the groove.

[0051] Optionally, the step of spraying the anti-penetration agent coating on the surface of the printed product to form a waterproof layer specifically includes: spraying the water-repellent anti-penetration agent coating on the surface of the printed product, spraying 2 to 3 times, and drying for 30 minutes. At this time, in order to obtain a better waterproof effect, it is recommended to spray 2 to 3 times. During the spraying process, attention should be paid to controlling the speed and distance of the spraying to ensure that the coating is uniform and without omissions. At the same time, spraying the water-repellent anti-penetration agent coating on the surface of the printed product is an effective waterproof treatment measure. It can not only significantly improve the waterproof performance and weather resistance of the product, but also improve the aesthetics and ease of maintenance of the product to a certain extent.

[0052] Optionally, the step of spraying an adhesion promoter on the dried waterproof layer on the surface of the printed product may specifically include: spraying an interface agent on the surface of the printed product, spraying 2 to 3 times, and drying for 30 minutes. Spraying an interface agent on the surface of the printed product is an effective surface treatment measure. It can significantly enhance the bonding ability between the product surface and other materials, improve the durability and construction efficiency of the product, and may improve the appearance of the product.

[0053] In an optional embodiment, the step of embedding the tendon material into the first groove of the sculpture and filling it with an adhesive may specifically include: using construction glue and talcum powder to make an adhesive, using glass cloth as the tendon material, and filling the first groove; brushing the adhesive once, pasting a layer of glass cloth, and repeating this 3 to 5 times. By brushing the adhesive and pasting the glass cloth many times, a multi-layer composite structure is formed. This structure not only improves the overall strength of the joint, but also effectively disperses and resists external stress, thereby preventing cracking or deformation problems caused by weak structure. The ratio of construction glue and talcum powder makes the adhesive have good weather resistance and aging resistance. The glass cloth, with its corrosion resistance and wear resistance, further enhances the durability of the filling layer. This combination can ensure that the filling part remains stable during long-term use and extend the service life of the product.

[0054] In an optional embodiment, automotive putty or polyurea is used to scrape and polish the surface of the printed product. Putty has excellent filling properties and can easily fill depressions, holes or uneven areas on the surface of the printed product to make the surface smoother. It has good adhesion to a variety of materials (including metals, plastics, etc.), which can ensure that the surface after scraping is stable and reliable. After drying, the surface of the putty is relatively soft and can be easily trimmed with a polishing tool to achieve the desired smoothness and glossiness.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
