Description

Technical Field

[0001] This utility model relates to the field of quartz plate technology, specifically a composite wood grain quartz stone structure. Background Technology

[0002] Traditional artificial quartz stone uses petroleum-based unsaturated polyester resins (such as orthophthalic and isophthalic resins) as binders, which can produce quartz slabs with high hardness and corrosion resistance. To enhance the texture of quartz slabs, textures are formed by layering and pressing during the molding process. However, this method results in relatively simple textures with poor scratch resistance. Alternatively, patterns can be imprinted onto the quartz slab using a hot press. This method fails to simulate the layering and three-dimensionality of natural wood grain, thus limiting the richness of the quartz stone's surface structure. Utility Model Content

[0003] The purpose of this invention is to provide a composite wood grain quartz stone structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a composite wood grain quartz stone structure, comprising a base plate, the upper surface of which is provided with a plurality of connecting holes, a balancing layer on the upper surface of which is provided, and a protruding tip connected to a first connecting hole on the lower surface of the balancing layer, the density of which is...

[0005] 1.6g / cm 3 This ensures the connection stability between the base plate and the balancing layer. The low density of the rubber in the balancing layer and the outer surface layer can improve the impact resistance of the quartz plate.

[0006] The outer surface layer is fixedly connected to the balancing layer. The upper surface of the balancing layer also has several bonding holes, and the lower surface of the outer surface layer has protrusions corresponding to the bonding holes. The density of the outer surface layer is 1.8 g / cm³. 3 Increasing the density of the outer surface layer can also effectively improve the scratch resistance of the textured wood grain layer;

[0007] The textured wood grain layer is formed by pressing it onto the outer surface of the surface using a dynamically temperature-controlled hot press mold. The depth of the textured wood grain layer is 0.2–0.8 mm, and the texture resolution of the textured wood grain layer is 200 dpi, presenting a more realistic wood grain and resulting in a better decorative effect for the quartz board.

[0008] Furthermore, the upper and lower surfaces of the balancing layer are connected to the outer surface layer and the base plate through the first curing layer and the second curing layer. A two-component curing agent (benzoyl peroxide and isocyanate compound) is used, making the production of quartz plates more environmentally friendly and reducing VOC emissions.

[0009] Furthermore, the balancing layer has several honeycomb holes, which reduces the density of the balancing layer while maintaining bending strength, ensuring that the quartz plate has sufficient strength.

[0010] Furthermore, the quartz sand particle size of the base plate is 2-3 mm, the quartz sand particle size of the balancing layer is 1-2 mm, and the quartz sand particle size of the outer surface layer is 0.1-1 mm. By precisely controlling the particle size distribution of quartz sand in different layers, a fibrous base structure that mimics natural wood is formed, making the quartz board look more like a wooden board.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) Quartz slabs are formed by a base plate, a balance layer and an outer surface layer with different quartz sand particle sizes. A three-dimensional carving with a wood grain depth of 0.2 to 0.8 mm is pressed into the outer surface layer, and the texture resolution reaches 200 dpi. Quartz slabs have more realistic wood grain.

[0013] (2) The density of the balance layer is lower than that of the outer surface layer, which has a certain buffering effect and can improve the impact resistance of the quartz plate. When an object collides with the quartz plate, the quartz plate is not easy to break.

[0014] (3) The balance layer is a honeycomb-shaped lightweight aggregate, which can reduce the density of the balance layer and maintain the flexural strength of the balance layer, thus saving the amount of quartz sand used. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example:

[0021] Please see Figure 1-3 This utility model provides a technical solution: a composite wood grain quartz stone structure, including a base plate 7, the upper surface of the base plate 7 having a plurality of connecting holes 9, the upper surface of the base plate 7 having a balancing layer 5, the lower surface of the balancing layer 5 having a protruding tip 8 connected to the first connecting hole 9, and the density of the balancing layer 5 being 1.6 g / cm³. 3 The base plate 7 is made of quartz sand. The joint hole 9 is a pit that is naturally present on the uneven base plate 7. When the balancing layer 5 is arranged on the base plate 7, the quartz sand in the balancing layer 5 is filled with the pit of the base plate 7 by vibration, thereby forming the protrusion 8, ensuring that the base plate 7 and the balancing layer 5 are integrally formed.

[0022] The outer surface layer 3 is fixedly connected to the balancing layer 5. The upper surface of the balancing layer 5 also has several connecting holes 9, and the lower surface of the outer surface layer 3 has protrusions 8 corresponding to the connecting holes 9. The outer surface layer 3 and the balancing layer 5 are integrally formed, and the density of the outer surface layer 3 is 1.8 g / cm³. 3 The outer layer 3 has a higher density, which can improve the scratch resistance of the outer layer 3.

[0023] The raised wood grain layer 2 is formed by pressing the outer surface layer 3 with a dynamic temperature-controlled hot press mold. The depth of the raised wood grain layer 2 is 0.2-0.8mm, and the texture resolution of the raised wood grain layer 2 is 200dpi, which is clearer than the traditional embossing scheme and also gives the raised wood grain layer 2 a certain gloss. The raised wood grain layer 2, the outer surface layer 3, the first curing layer 4, the balancing layer 5, the second curing layer 6, and the base plate 7 form a quartz plate 1, which has a more realistic wood grain.

[0024] In this embodiment, as Figure 2 As shown, the upper and lower surfaces of the balancing layer 5 are connected to the outer surface layer 3 and the base plate 7 via the first curing layer 4 and the second curing layer 6. The first curing layer 4 and the second curing layer 6 use a two-component curing agent (benzoyl peroxide and isocyanate compound). When manufacturing the quartz plate 1, the VOC emission can be ≤50mg / m³. 3 The production process is more environmentally friendly.

[0025] In this embodiment, as Figure 3 As shown, the balancing layer 5 has a number of honeycomb holes 10. The honeycomb-shaped balancing layer 5 has a low density, which reduces the amount of quartz sand used. The porosity of the honeycomb gives the balancing layer 5 a low elastic modulus, which enables it to absorb and disperse impact loads well, preventing the quartz plate 1 from being damaged by collision.

[0026] In this embodiment, the quartz sand particle size of the base plate 7 is 2-3 mm, the quartz sand particle size of the balance layer 5 is 1-2 mm, and the quartz sand particle size of the outer surface layer 3 is 0.1-1 mm. Through this gradient ratio, different texture effects can be formed in different layers of the quartz plate 1, thereby solving the problem of the traditional quartz stone having a single texture and insufficient wood grain layering, making the product more beautiful and decorative.

[0027] Specifically, during use, functionalized coupling agents (such as silane coupling agents) and nano-reinforcing materials (such as nano-silica) are introduced into the quartz sand to optimize the interfacial bonding force between the bio-based resin and the quartz sand. By controlling the copolymerization ratio of the bio-based components (such as plant polyols with a content of ≥30%) in the resin and the synthetic resin, the curing shrinkage rate is reduced, and cracking defects in the quartz plate 1 are prevented.

[0028] When placing quartz sand into the mold, the particle size distribution of the quartz sand in different layers is precisely controlled (gradient ratio of 0.1 to 3 mm). The quartz sand particle size of the base plate 7 is 2 to 3 mm, the quartz sand particle size of the balance layer 5 is 1 to 2 mm, and the quartz sand particle size of the outer surface layer 3 is 0.1 to 1 mm, forming a fibrous base structure that resembles natural wood. Through a dynamic temperature-controlled hot pressing mold, a pressure of 0.5 to 1.2 MPa is applied during the semi-curing stage of the bio-based resin (viscosity 1000-1500 mPa·s) to achieve three-dimensional carving with a wood grain depth of 0.2 to 0.8 mm, forming a textured wood grain layer 2 on the outer surface layer 3. The texture resolution is expected to reach 200 dpi, enhancing the gloss of the outer surface layer 3.

[0029] The curing temperature reaches 80-100℃ through the synergistic effect of infrared radiation and microwave-assisted heating. A two-component curing agent (benzoyl peroxide and isocyanate compound) is used to control the difference in crosslinking rate from the surface to the inner layer of the resin, forming a high-density (1.8 g / cm³) outer layer. 3 ), Balance layer 5 flexible buffer (1.6g / cm) 3 The composite structure of the quartz plate 1 has an impact resistance of 15 kJ / m. 2 Quartz plate 1 is not easily broken.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
