Description

Technical Field

[0001] This invention belongs to the field of building decoration technology, and in particular relates to a production method of UH-PC, a self-luminous glass fiber prefabricated building decoration component. Background Art

[0002] Long-afterglow luminescent materials are a type of photoluminescent material. They are substances that absorb energy and continue to emit light after excitation stops. Since they do not require a power source, long-afterglow luminescent materials can release the light energy they store and emit light, making them applicable in many fields.

[0003] Photoluminescent concrete incorporates long-afterglow luminescent powder into concrete in a specific manner, allowing it to absorb and store sunlight during the day and then slowly release the stored energy at night for several hours or even more than ten hours. Photoluminescent ultra-high performance concrete products can be applied to cultural buildings, parks, highway signage, and other fields.

[0004] However, in the current process of preparing luminescent concrete, long-afterglow luminescent materials are generally not treated. As a result, a large amount of cement solidifies on the outer surface of the long-afterglow luminescent material after the final processing, which affects the luminescence effect of the long-afterglow luminescent material. In addition, in order to ensure its own luminescence effect, a large amount of long-afterglow luminescent material is added to the general luminescent concrete, which increases the manufacturing cost and also has a certain impact on the strength of the component itself. Summary of the Invention

[0005] This invention provides a production method for self-luminous glass fiber precast building decorative components UH-PC, aiming to solve the problems of the current practice of not treating long-afterglow luminescent materials during the preparation of luminescent concrete, resulting in a large amount of cement solidifying on the outer surface of the long-afterglow luminescent materials after final processing, affecting the luminescence effect of the long-afterglow luminescent materials. Furthermore, in general luminescent concrete, a large amount of long-afterglow luminescent materials are added to ensure its self-luminescence effect, which increases the manufacturing cost and also affects the strength of the component itself.

[0006] This invention is achieved through a method for producing a self-luminous glass fiber precast architectural decorative component (UH-PC), comprising the following steps:

[0007] S1. Luminescent material treatment: Using a mixer, add long afterglow material into the mixer, and then gradually add cement-based retarder to the inside. Use cement-based retarder to wet the surface of long afterglow material to prevent dripping.

[0008] S2. Mixing of luminescent materials: Add short-cut optical fibers at a volume ratio of 2% of long-afterglow material to cement, and mix evenly again using a mixer. Add silicate cement slowly while stirring at a ratio of 0.1 to 1:3 of long-afterglow material to cement, and mix evenly to obtain modified long-afterglow material.

[0009] S3. One-time casting: Mix 20-40 parts of modified long afterglow material, 20-40 parts of 80-120 mesh quartz sand, and 10-30 parts of cement evenly, add 0.5 parts of water-reducing agent and 1-6 parts of water and stir. After forming a slurry, spray or pour it onto the surface of the mold.

[0010] S4. Concrete preparation: Mix 30-50 parts cement, 5-20 parts active powder, 50-100 parts quartz sand, 1-7 parts fiber, 1-5 parts dispersible latex powder, and 0.1-0.5 parts defoamer evenly. Add water at a mass ratio of 5-10% of the cement-based mixture and stir with a mixer to obtain ultra-high performance concrete slurry.

[0011] S5. Secondary pouring: The prepared ultra-high performance concrete slurry is sprayed or poured into the mold in S3.

[0012] S6. Demolding and steam curing: After natural curing, the sample is demolded and placed in a steam curing chamber. After steam curing for 48 hours, the sample is taken out, and photoluminescent ultra-high performance concrete products are successfully obtained.

[0013] Preferably, in S1, the cement-based retarder is an aqueous solution of one or more of gluconate, lignin sulfonate, and sodium hexametaphosphate.

[0014] Preferably, in step S4, the active powder is a mixture of metakaolin, silica fume, and mineral powder in a ratio of 1:1:1.

[0015] Preferably, in step S4, the cement-based mixture and water need to be stirred for 10-15 minutes.

[0016] Preferably, in step S1, the mixer used is a forced mixer.

[0017] Preferably, in step S3, a cement slurry spraying machine is used to spray the modified long afterglow material.

[0018] Preferably, in step S6, natural curing is required for 24 hours before demolding.

[0019] Preferably, in step S6, the internal temperature of the steam oven is maintained at 90°C.

[0020] Preferably, in step S4, the mixer used is a shear mixer.

[0021] Beneficial effects

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The production method of UH-PC self-luminous glass fiber prefabricated building decoration component of the present invention involves pre-wetting the surface of the long afterglow material with cement-based retarder so that the cement does not solidify on the surface. After the steam curing process, the surface of the component is directly rinsed with clean water to wash off the cement adhering to the surface of the long afterglow material. This avoids cement solidifying on the outer surface of the long afterglow material and affecting the luminous properties of the long afterglow material itself, thus ensuring the luminous effect of the long afterglow material and improving the practicality of the method.

[0024] (2) The production method of UH-PC self-luminous glass fiber precast building decoration component of the present invention involves adding a certain proportion of short-cut optical fibers to long afterglow material and mixing them. When the long afterglow material emits light, the optical fibers can enhance the visual brightness of the light emitted by the long afterglow material, thereby reducing the amount of long afterglow material used, thus reducing the cost of photoluminescent concrete and improving the cost-effectiveness. At the same time, the optical fibers can play a role in strengthening and toughening, and can also prevent cracking of the component body, thereby improving the practicality of the method.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Please see Figure 1 This invention provides a technical solution: a method for producing a self-luminous glass fiber precast building decoration component UH-PC, comprising the following steps:

[0028] S1. Luminescent material treatment: Using a mixer, add long afterglow material into the mixer, and then gradually add cement-based retarder to the inside. Use cement-based retarder to wet the surface of long afterglow material to prevent dripping.

[0029] S2. Mixing of luminescent materials: Add short-cut optical fibers at a volume ratio of 2% of long-afterglow material to cement, and mix evenly again using a mixer. Add silicate cement slowly while stirring at a ratio of 0.1 to 1:3 of long-afterglow material to cement, and mix evenly to obtain modified long-afterglow material.

[0030] S3. One-time casting: Mix 20-40 parts of modified long afterglow material, 20-40 parts of 80-120 mesh quartz sand, and 10-30 parts of cement evenly, add 0.5 parts of water-reducing agent and 1-6 parts of water and stir. After forming a slurry, spray or pour it onto the surface of the mold.

[0031] S4. Concrete preparation: Mix 30-50 parts cement, 5-20 parts active powder, 50-100 parts quartz sand, 1-7 parts fiber, 1-5 parts dispersible latex powder, and 0.1-0.5 parts defoamer evenly. Add water at a mass ratio of 5-10% of the cement-based mixture and stir with a mixer to obtain ultra-high performance concrete slurry.

[0032] S5. Secondary pouring: The prepared ultra-high performance concrete slurry is sprayed or poured into the mold in S3.

[0033] S6. Demolding and steam curing: After natural curing, the sample is demolded and placed in a steam curing chamber. After steam curing for 48 hours, the sample is taken out, and photoluminescent ultra-high performance concrete products are successfully obtained.

[0034] In this embodiment, by pre-wetting the surface of the long-afterglow material with a cement-based retarder, the cement will not solidify on its surface. After the steam curing process, the surface of the component can be directly rinsed with clean water to wash off the cement adhering to the surface of the long-afterglow material. This prevents the cement from solidifying on the outer surface of the long-afterglow material and affecting its luminescence performance, thus ensuring the luminescence effect of the long-afterglow material.

[0035] Furthermore, this method involves adding a certain proportion of short-cut optical fibers to the long-afterglow material and mixing it. When the long-afterglow material emits light, the optical fibers can enhance the visual brightness of the light emitted by the long-afterglow material, thereby reducing the amount of long-afterglow material used, thus reducing the cost of photoluminescent concrete and improving its cost-effectiveness. At the same time, the optical fibers can also play a role in strengthening and toughening, and can also prevent cracking of the component itself.

[0036] Meanwhile, during the mixing process of long-afterglow luminescent materials and optical fibers, cement is used to coat both materials to avoid the impact of the retarding material on the overall strength of the concrete, while not affecting the bonding force between the materials and the base concrete. In the subsequent washing process, the water used can also be recycled, which has a certain degree of environmental friendliness.

[0037] Furthermore, in S1, the cement-based retarder is an aqueous solution of one or more of gluconate, lignin sulfonate, and sodium hexametaphosphate.

[0038] In this embodiment, materials such as gluconate, lignin sulfonate, and sodium hexametaphosphate can slow down the setting time of cement without affecting the overall strength of the cement after setting, and can also improve the overall structural strength.

[0039] Furthermore, in S4, the active powder is a mixture of metakaolin, silica fume, and mineral powder in a 1:1:1 ratio.

[0040] In this embodiment, the active component in metakaolin, aluminum silicate hydrate, reacts with calcium hydroxide precipitated from cement hydration to generate hydrated calcium aluminum feldspar and secondary CSH gel, which have gel properties. These hydration products not only enhance the compressive, flexural, and splitting tensile strength of concrete, but also increase the flexural toughness of fiber-reinforced concrete.

[0041] Silica fume can enhance the strength and durability of concrete: it can be added to concrete as an admixture, filling the micropores in the concrete, reducing the porosity in the cement paste, improving the density and strength of the concrete, and extending its service life.

[0042] Mineral powder can effectively improve the compressive strength of concrete and reduce its cost. It also has significant effects on inhibiting alkali-aggregate reaction, reducing heat of hydration, minimizing early-stage temperature cracks in concrete structures, and improving concrete density, impermeability, and erosion resistance.

[0043] Furthermore, in step S4, the cement-based mixture needs to be stirred with water for 10-15 minutes.

[0044] Furthermore, in S1, the mixer used is a forced mixer.

[0045] Furthermore, in step S3, a cement slurry spraying machine is used to spray the modified long afterglow material.

[0046] Furthermore, in S6, natural curing requires 24 hours before demolding.

[0047] Furthermore, in S6, the internal temperature of the steam oven is maintained at 90°C.

[0048] Furthermore, in S4, the mixer used is a shear mixer.

[0049] The working principle and usage process of this invention are as follows: This invention pre-wets the surface of the long-afterglow material with a cement-based retarder, preventing cement from solidifying on its surface. After the steam curing process, the surface of the component is directly rinsed with clean water to wash away any cement adhering to the surface of the long-afterglow material. This prevents cement from solidifying on the outer surface of the long-afterglow material and affecting its luminescence performance, thus ensuring the luminescence effect of the long-afterglow material. Simultaneously, by adding a certain proportion of short-cut optical fibers to the long-afterglow material and mixing it, the optical fibers enhance the visual brightness of the light emitted by the long-afterglow material during luminescence, thereby reducing the amount of long-afterglow material used and thus reducing the cost of photoluminescent concrete, improving cost-effectiveness. Furthermore, the optical fibers also act as reinforcement and toughening agents, preventing cracking of the component itself.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
