Description
Technical Field
[0001] The present invention relates to a method for manufacturing an on-site cast plastic runway with molded patterns, and belongs to the technical field of plastic runways. Background Art
[0002] Plastic runways are mainly divided into on-site cast type and factory prefabricated on-site bonded type. For the factory prefabricated on-site bonded type rubber runway, the adopted process route is: using vulcanized rubber to prepare finished coils with anti-slip patterns in the factory in advance through embossing and vulcanization, and then bonding them on-site. Its advantages are that the patterns are uniform and beautiful, the performance is stable, and the use effect is good, which has been unanimously recognized by the international sports community and has also become one of the preferred venues for international major competitions; however, its disadvantages are high cost, and when the prefabricated coils in the factory are bonded on-site, it is easy to have problems such as delamination and uneven joints, and the adaptability to the foundation is not good. For the on-site cast type, liquid synthetic materials are mixed and paved on-site and cured on-site. Its advantages are on-site casting and molding, good adaptability to the foundation and site, easy construction and paving, and low cost; its disadvantages are: during the implementation process, a firm, uniform, and beautiful anti-slip pattern cannot be made on-site. All along, due to different on-site conditions, especially there are certain uncertain errors in the site flatness, the sizes and shapes of the paving areas of the runway are different, and it is very difficult to manually mold the patterns on-site, especially in the case of local protrusions or local depressions in the bottom rubber layer and the special-shaped areas at the corners of the site, which is almost impossible to achieve. At present, there is no complete on-site cast plastic runway with manually molded patterns globally.
[0003] The existing methods for manufacturing the anti-slip layer on the surface of on-site cast plastic runways mainly include: particle sticking method, particle spraying method, and self-knurling spraying method.
[0004] The particle sticking method is to first pave a layer of glue solution about 1-3 mm thick on the bottom rubber layer, and then, before the glue solution is cured, evenly sprinkle the particles on the surface of the glue solution. After the glue solution is completely cured, some particles are naturally bonded to the surface of the glue layer. After removing the unbonded particles, a granular anti-slip surface layer is formed. The disadvantage of the particle sticking method is that some particles are not firmly bonded and there will be a phenomenon of particle shedding;
[0005] The particle spraying method is to spray a mixture of rubber particles and plastic on the bottom rubber layer of the plastic runway, so that the glue solution wraps the particles and distributes on the bottom rubber layer. After the glue layer is cured, an anti-slip layer is formed; the disadvantage of the particle spraying method is that due to the irregular spraying, it is very difficult to make the particle spraying uniform, the anti-slip performance is non-uniform, and the aesthetics is poor.
[0006] The spraying self-texturing method involves spraying a plasticizable glue solution on the base glue layer of a plastic runway. After the glue solution lands on the base glue layer, it naturally forms convex granules. After the glue layer cures, an anti-slip layer is formed. The disadvantage is that due to the irregular spraying method, it is difficult to make the surface layer uniform, resulting in poor aesthetics and anti-slip performance.
[0007] The on-site casting type plastic runway has good adaptability to the foundation and low cost, making it the most widely paved type of plastic runway. However, as mentioned above, the anti-slip layer pattern of the plastic runway made by the on-site casting method has irregular convex and concave patterns and non-uniform anti-slip performance. How to make a regular, uniform, non-detachable, beautiful and practical anti-slip layer pattern for a plastic runway is a difficult problem in the plastic runway industry. Industry manufacturers at home and abroad have made unremitting explorations but have not found an effective solution.
[0008] After years of exploration and experimentation, the inventor of the present invention has invented a manufacturing method for an on-site casting type plastic runway with molded patterns. The convex and concave patterns that make up the anti-slip layer on the surface of the plastic runway are arranged in an orderly manner, with similar shapes, similar sizes, beautiful and neat appearance, and good anti-slip effect. The method is easy to operate and suitable for mechanized construction. Summary of the Invention

[0095] (2) On-site preparation of a plastic runway with a ribbed convex pattern.
[0096] 1. Lay the bottom glue layer of the plastic runway on-site and let it cure naturally at room temperature. Its thickness is determined according to the total thickness of the runway to be laid. For a standard 13-mm plastic runway, it is 10 mm.
[0097] 2. First, on the primer layer of the plastic runway, cut a shaping mold according to the size and shape of the primer layer, and pre-lay it on the primer layer so that the mold covers the entire predetermined surface layer for later use. The shaping mold used in this Example 1 is a commercially available plastic mesh belt with hexagonal straight through holes for protective nets, with a mesh hole diameter of 6 mm, a spacing of 1 mm, and a thickness of 2 mm;
[0098] Take 1 kg of the above-mentioned Component A and 3 kg of Component B, place them in a barrel-shaped container used as a mixing barrel, directly stir the glue liquid with an electric stirrer until it is evenly mixed, pour the above-mentioned mixed glue liquid onto the mold, and use an iron trowel to smear it into the holes of the shaping mold pre-laid on the primer layer of the plastic runway. The holes of the shaping mold shape the glue liquid. After shaping and before the glue liquid cures, demold. After demolding, evenly arranged and distributed prism-shaped convex grains with a diameter of 6 mm, a height of 2 mm, and a spacing of 1 mm are left on the surface of the primer layer. The shaped glue liquid cures naturally at room temperature to form a prism-shaped convex grain anti-slip layer; As Figure 1-1 shown, it is a top view structural schematic diagram of a site-cast plastic runway with prism-shaped convex grain patterns made in Example 1 of the present invention; As Figure 1-2 shown, it is a cross-sectional structural schematic diagram of a site-cast plastic runway with prism-shaped convex grain molded patterns made in Example 1 of the present invention; Among them, 1-1 is the prism-shaped convex grain, 1-2 is the first surface anti-slip layer, and 1-3 is the first plastic runway primer layer; The site-cast plastic runway with prism-shaped convex grain molded patterns made in Example 1 of the present invention includes a first plastic runway primer layer 1-3 and a first surface anti-slip layer 1-2.

The shaping mold used in this Example 2 is a commercially available plastic mesh belt with hexagonal straight through holes for protective nets, with a mesh hole diameter of 3 mm, a spacing of 1 mm, and a thickness of 1 mm;

[0109] Example 4
[0110] On-site production of a plastic runway with bean shell-shaped pits:
[0111] On-site lay the primer layer of the plastic runway and let it cure naturally at room temperature. Its thickness is determined according to the total thickness of the runway to be laid. For a standard 13-mm plastic runway, it is 10 mm.
[0112] First, on the primer layer of the plastic runway, cut the plastic mold according to the size and shape of the primer layer, pre-lay it on the primer layer, and make the mold cover the entire predetermined surface layer for later use; the plastic mold used in this Example 4 is a commercially available plastic mesh belt with hexagonal straight through holes for protective nets, with a mesh hole diameter of 4 mm, a spacing of 1 mm, and a thickness of 1 mm;
[0113] Take the two-component plasticizing glue prepared in the above Example 1, according to the mixing ratio of 1:3, take 1 kg of component A and 3 kg of component B and place them in a bucket-shaped container as a stirring bucket. Use an electric stirrer to directly stir the glue liquid until it is evenly stirred. Pour the above glue liquid onto a plastic mold pre-laid on the base glue layer, and use an iron trowel to smear it into the straight through holes of the mold. After all the straight through holes of the plastic mold are filled with the glue liquid, then use the iron trowel. While perpendicular to the mold, press on the scraping glue surface of the plastic mold. The glue liquid in the center of the hole will be scraped out, and the glue liquid will accumulate at the intervals of the plastic mold. Then, before the glue liquid cures, perform demolding. After demolding, a pit with a central depression depth of 2 mm in the shape of a bean shell will be left on the base glue layer. The plasticized glue liquid cures naturally at room temperature to form a non-slip layer with bean shell-shaped pits; as Figure 4-1 shown, it is a top view structural schematic diagram of a site-cast plastic runway with bean shell-shaped pit molded patterns made in Example 4 of the present invention; as Figure 4-2 shown, it is a cross-sectional structural schematic diagram of a site-cast plastic runway with bean shell-shaped pit patterns made in Example 4 of the present invention; wherein, 4-1 is a bean shell-shaped pit, 4-2 is a fourth surface non-slip layer, and 4-3 is a fourth plastic runway base glue layer; the site-cast plastic runway with bean shell-shaped pit molded patterns made in Example 4 of the present invention includes a fourth plastic runway base glue layer 4-3 and a fourth surface non-slip layer 4-2. The fourth surface non-slip layer 4-2 is arranged with patterns composed of bean shell-shaped pits 4-1. The central depression depth of the bean shell-shaped pits is 2 mm. The thickness of the fourth plastic runway base glue layer 4-3 is 10 mm, and the thickness of the fourth surface non-slip layer 4-2 is 3 mm.
[0114] The manufacturing method of the site-cast plastic runway with molded patterns of the present invention uses a plastic mold made of a soft material, which is a mesh belt or a perforated belt, including a soft plastic mesh belt or a plastic soft rubber plate. It can be prepared according to the actual situation on site by on-site cutting to prepare plastic molds suitable for different construction areas with different shapes, sizes, etc. It is not restricted by the construction area, and the soft plastic mold can fit well on the surface of the base glue. There is no influence of the local flatness error of the foundation on the height, depth, and shape of the molded patterns. The operation is simple and easy to popularize. The plastic mold uses commercially available molded products, the materials are easy to obtain, the cost is low, and the construction cost is low. It is a major technical breakthrough in the field of production and construction of site-cast plastic runways; the surface non-slip layer of the produced plastic runway is arranged with concave and convex in an orderly manner, with similar shapes, similar sizes, beautiful and neat. The anti-slip convex particles of the produced runway have the same height and are firmly combined with the base glue. Compared with existing varieties, the number and area of anti-slip contact points are increased, and the anti-slip effect is good; the plasticizing glue prepared by the present invention has good plasticizing effect, is resistant to aging and wear, has good compatibility with the base glue layer, is firmly bonded, and has a lower viscosity, which is suitable for on-site construction operations; all raw materials required for production are maturely sold products in the market, and the production process is simple and safe.
