Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a luminous brightening floor containing inorganic polymer silicone resin. Background Art

[0002] In modern construction and road engineering, the performance requirements for floor materials are getting higher and higher, especially in terms of aesthetics, durability and functionality. The floor must not only have excellent decorative effects, but also good wear resistance and durability, and also have special luminous properties, so that it can have a wide range of application prospects in cultural and tourism paving, commercial spaces, public places and residential areas.

[0003] Although traditional concrete or asphalt floors perform well in terms of structural stability and cost-effectiveness, they have certain limitations in terms of aesthetics and functionality. For example, ordinary concrete floors are single-colored, rough in appearance, and prone to cracks and wear after long-term use, affecting their appearance and service life. In addition, traditional floors lack sufficient brightness at night or in low-light environments, limiting their application in certain specific occasions. To overcome these limitations, researchers have been exploring new floor materials and technologies.

[0004] Chinese patent CN 114836065 B discloses a water-based inorganic antifungal ceramic topcoat and its preparation method and application. The ceramic topcoat comprises the following components by weight: 5-10 parts of fungicide, 0.1-0.5 parts of herbicide, 30-60 parts of inorganic resin, 20-40 parts of filler, 10-30 parts of silica sol and 0.1-0.8 parts of additive. This invention solves the technical problems of gloss loss, powdering and mold growth of topcoat caused by the metabolism of microorganisms on the surface of wet organic coatings and the aging of the organic coatings themselves, and achieves the technical effect of significantly inhibiting the growth of bacteria, microorganisms and plants on the surface of the coating. However, fillers are one of the main raw materials for improving the performance of ceramic topcoats. In this invention, fillers are directly mixed with inorganic resins and silica sols, and are prone to agglomeration after being placed for a long time, which affects the wear resistance and crack resistance of the coating.

[0005] Therefore, there is an urgent need for a luminous brightening floor containing an inorganic polymer silicone resin to have good wear resistance and crack resistance. Summary of the invention

[0006] In view of the existing technical problems, the purpose of the present invention is to provide a luminous brightening floor containing inorganic polymer silicone resin. The floor of the present invention has good wear resistance, good anti-fouling effect, good crack resistance, can reduce walking noise, reduce the heat island effect, and has the characteristics of luminous brightening effect and good decorative effect, and has a wide range of application scenarios.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] The present invention provides a luminous brightening floor containing inorganic polymer silicone resin, wherein the floor comprises from bottom to top: a plain soil ramming layer, a colored concrete layer, a colored aggregate polymer surface layer, a graphic acid coloring layer, and an elastic resin protective layer; wherein:

[0009] The elastic resin protective layer comprises the following raw materials by weight: 35-50 parts of inorganic resin, 15-25 parts of modified carbon nanotubes, 2-5 parts of hollow microspheres, 0.4-0.8 parts of dispersant, and 40-60 parts of water.

[0010] In some embodiments, a plurality of light guide tubes are laterally inserted through the rammed earth layer, and light guide fibers or LED light strips are inserted through the light guide tubes.

[0011] The reaction mechanism and effects of the present invention are as follows:

[0012] 1. Carbon nanotubes have a unique structure and excellent physical and chemical properties, which can significantly improve the performance of the coating, making the coating have excellent adhesion, wear resistance, corrosion resistance and anti-fouling properties. However, the properties of carbon nanotubes themselves lead to poor dispersion, affecting performance.

[0013] The present invention not only helps to improve the dispersibility of carbon nanotubes by inserting intermediates into the acidified carbon nanotubes, but also enhances their stability; then, by introducing hydrophilic ionic liquids through dispersion, grinding and ultrasonic treatment, the dispersibility of the modified carbon nanotubes in water can be further improved to form a more uniform and stable filler network structure. At the same time, when the ionic liquid covers the carbon nanotubes, the inorganic resin can move and unfold more flexibly on the surface of the carbon nanotubes when stretched by external forces, avoiding stress concentration, thereby reducing the risk of cracking of the material and improving the crack resistance of the material. In addition, the modified carbon nanotubes contain carbon-carbon double bonds, which may help to improve the compatibility with the dispersant, further avoid agglomeration, and improve the overall performance.

[0014] 2. Compared with polyamide fiber, poly fiber and viscose fiber, polypropylene fiber is light but strong. At the same time, polypropylene fiber has excellent electrical insulation and warmth retention, which can effectively improve the crack resistance of road base materials. However, the stability of polypropylene fiber under light and heat conditions is not satisfactory.

[0015] On the one hand, the present invention first uses benzophenone and N-vinyl acetamide to modify polypropylene fibers, and the modified primary polypropylene fibers can effectively improve stability. The applicant further grafts fumaric acid on the primary polypropylene fibers to effectively improve the dispersibility of the secondary polypropylene fibers in the matrix, thereby improving the interface bonding strength between the acrylic resin and the polypropylene fibers.

[0016] On the other hand, the present invention adds the prepared product 1 and product 2 for further modification to obtain modified polypropylene fiber. Nano-silicon dioxide and nano-calcium carbonate cannot be dispersed evenly when directly blended with raw materials. After agglomeration, weak areas will be generated in the system, affecting the compactness of the colored aggregate polymer surface layer. The present invention firstly utilizes sodium acrylate to modify nano-silicon dioxide, which is grafted onto secondary polypropylene fibers to help improve the dispersibility of the modified polypropylene fibers; at the same time, the nano-silicon dioxide particles make the surface of the modified polypropylene fibers uneven, thereby enhancing the bonding force between the modified polypropylene fibers and the raw materials, improving the material's crack resistance, and the nano-silicon dioxide particles can block part of the pores of the road base material, reducing water evaporation, thereby reducing the possibility of volume shrinkage and cracking of the colored aggregate polymer surface layer. The second is to modify nano calcium carbonate with 1-(3-aminopropyl) imidazole and KH560. After grafting to secondary polypropylene fibers, it helps to make the surface of polypropylene fibers easy to infiltrate, and further promotes the dispersion of modified polypropylene fibers; at the same time, nano calcium carbonate can not only fill the defects and weaknesses on the surface of secondary polypropylene fibers and improve the overall strength of the fibers, but also increase the surface roughness of secondary polypropylene fibers, thereby improving the mechanical properties of concrete; in addition, the five-membered ring in the imidazole group has a conjugated system, which can absorb ultraviolet light and improve the light stability and thermal stability of polypropylene fiber materials.

[0017] In some embodiments, the inorganic resin is sodium silicate resin and / or potassium silicate resin.

[0100] Effect evaluation:

[0101] The floors prepared in the above-mentioned Examples 1-8 and Comparative Examples 1-2 were tested and analyzed, and the specific results are shown in Table 1.

[0102] The preparation method of the floor is as follows: the rammed earth layer is constructed according to the national standard, and a number of light guides are inserted horizontally, and light guide fibers or LED light strips are inserted in the light guides; the colored concrete layer is spread on the rammed earth layer with C40 fine stone colored concrete, with a thickness of 10cm; the colored aggregate polymer surface layer is mixed and stirred evenly according to the ratio of each raw material and then spread on the colored concrete layer, with a thickness of 1cm and the overall flatness and smoothness. It is strictly forbidden to cover the surface of the circular light guide rod to affect the light transmittance. After the colored aggregate polymer surface layer is made, the ground is first polished with a 500-mesh resin grinding disc, and then citric acid and oxalic acid are mixed in a volume ratio of 1:1 and sprayed on the polished ground, and then the copper brush plate installed with a stone renovation machine is used to brush the corroded surface, and after rinsing with clean water, it is finally cleaned with alkaline detergent and detergent. After drying, the next process can be constructed; the graphic acid coloring layer is sprayed or hand-painted on the surface of the colored aggregate polymer surface layer with metal ion acid colorant (metal ion acid colorant is Stone Tone Concrete Stain (concrete acid colorant); the elastic resin protective layer is mixed and stirred evenly according to the proportion of each raw material, and then evenly applied on the surface of the colored aggregate polymer surface layer and the graphic acid coloring layer by spraying or rolling, with a thickness of 0.5cm.

[0108] From the results in Table 1, it can be seen that the floor prepared in Examples 1-3 has good wear resistance and crack resistance, and has good market value.

[0109] Examples 4-5 and Comparative Example 1, compared with Example 1, when preparing modified carbon nanotubes, Example 4 changes the mass ratio of acidified carbon nanotubes and intermediates, and the stability is weakened; Example 5 changes the mass ratio of powder and ionic liquid, and the hydrophilicity is weakened, which will affect the wear resistance and crack resistance of the floor; and Comparative Example 1 uses an equal amount of commercially available carbon nanotubes to replace modified carbon nanotube A, which greatly reduces the wear resistance and crack resistance of the floor.

[0110] In Examples 6-8 and Comparative Example 2, compared with Example 1, when preparing modified polypropylene fibers, Example 6 changes the mass ratio of primary polypropylene fibers and fumaric acid, resulting in decreased dispersibility; Examples 7-8 change the mass ratio of product 1, product 2, and secondary polypropylene fibers, resulting in decreased density and decreased roughness, which will affect the crack resistance of the floor; while Comparative Example 2 uses an equal amount of commercially available polypropylene fibers to replace modified polypropylene fibers A, resulting in a significant decrease in the crack resistance of the floor. In addition, since the modified polypropylene fibers are the raw materials for the colored aggregate polymer surface layer, they have little effect on the wear resistance of the floor surface layer.
