Description

Technical Field

[0001] The invention relates to materials, in particular to a natural stone-like composite material. Background Art

[0002] With the continuous development of social economy, people's requirements for quality of life and living environment are constantly improving. Decorative materials with natural imitation stone, simplicity and high grade have become the mainstream of consumption. Therefore, scientific research and technical personnel have been using various technological means and materials to imitate the texture of natural stone. Summary of the invention

[0003] The invention provides a natural stone imitation composite material.

[0004] The technical solution of the present invention: A natural imitation stone, which is cast by concrete; the concrete is made by mixing high-strength white cement with stone powder and gravel of various colors and different particle sizes and then adding water to mix; when casting, the concrete is arranged to form the texture and pattern of the natural imitation stone; the casting method is as follows: concrete is injected into a mold, and before the concrete is solidified, a plurality of partitions are inserted to separate the unsolidified concrete, and the concrete is solidified to form a plurality of natural imitation stones.

[0005] The above technical solution is further refined, and a mesh is arranged inside the imitation natural stone.

[0006] The above technical solution is further refined, and the mesh is a stainless steel wire mesh or a glass fiber mesh or a basalt fiber mesh or an aramid fiber mesh or a carbon fiber mesh or a natural fiber mesh or chopped fibers or a fiber felt.

[0007] The above technical solution is further refined, the mold is made of steel plate; the partition is a stainless steel plate or a composite plate or tempered glass.

[0008] The above technical solution is further refined. When high-strength white cement is mixed with stone powder and gravel of various colors and particle sizes, additives are added; the additives are epoxy resin or unsaturated polyester resin or acrylic resin or polyethylene vinyl acetate resin. Of course, other additives can also be used to further improve the bonding strength.

[0009] The above technical solution is further refined. When water is added to prepare concrete, admixtures are also added; the admixtures are high-efficiency water reducing agents and retarders to accurately adjust the fluidity and setting time of concrete to make it perfectly meet the needs of each link of subsequent production operations.

[0010] The above technical solution is further refined. When pouring concrete, the mold is vibrated with the aid of a vibrating rod or a vibrating table.

[0011] A composite material is formed by tightly combining the above-mentioned imitation natural stone material and a thermal insulation material.

[0012] The above technical solution is further refined, and the thermal insulation material is a foam board or a sandwich board.

[0013] The advantages of the present invention are reasonable design, ingenious conception, and the following beneficial effects: Imitation of natural stone: 1) Appearance: With highly simulated color, texture and pattern of natural stone, each finished product shows the unique natural beauty of natural stone. Whether it is the delicate stone veins or the rich and diverse color changes, it can be comparable to natural stone, adding an elegant and atmospheric atmosphere to the building and decorative space.

[0014] 2) Texture: Uniform and delicate, smooth and flat surface, comfortable touch. Compared with natural stone, it avoids the holes, cracks and defects that may exist in natural stone. The overall texture is more stable and consistent, giving people a refined and high-end feeling.

[0015] 3) Strength: It has excellent compressive strength and flexural strength, and can withstand large external forces without being easily broken or damaged. After rigorous testing, its strength index fully meets or even exceeds the relevant standards of building decoration materials, ensuring safety and reliability in various usage scenarios. Whether it is dry hanging on the exterior walls of high-rise buildings or paving on the ground where people frequently walk, it can maintain stable structural performance.

[0016] 4) Hardness: Mohs hardness is moderate (up to 6-7 according to requirements, which is the standard of natural marble and granite). While ensuring processing performance, it has good wear resistance and scratch resistance. Daily friction and collision will not easily leave marks. After long-term use, it can still maintain the surface finish and beauty, reducing maintenance costs and frequency. It is suitable for places with high requirements for wear resistance, such as the floor of commercial buildings, elevator cars, etc.: 5) Each imitation natural stone (formed by one pouring) has similarities and inconsistencies. In the three directions of X, Y, and Z, the products have a high degree of similarity, which ensures the coordination and consistency of the overall visual effect when installed and used on a large scale. This similarity makes the decorative space present a neat and unified aesthetic feeling. Whether it is a large area of ​​wall paving or a continuous ground splicing, it can create a harmonious and beautiful atmosphere and meet the requirements of architectural decoration for the overall style unity; at the same time, especially in the X direction, the subtle differences in the appearance of the stone surface are separated, avoiding the dull feeling brought by complete consistency, and being closer to the natural characteristics of natural stone. Each piece of product retains a certain uniqueness on the basis of similarity, making the entire decorative space full of natural and smart atmosphere, as if using real natural stone, showing high-end and personalized decorative taste. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a schematic diagram of the composite material structure.

[0018] Figure 2 It is a schematic diagram of the structure of a device for casting imitation natural stone.

[0019] In the figure, there are imitation natural stone 1, thermal insulation material 2, mold 3, partition 4, and mesh 5. DETAILED DESCRIPTION

[0020] like Figure 1 As shown, the composite material is composed of an imitation natural stone 1 and a thermal insulation material 2 which are tightly combined; the thermal insulation material 2 is a foam board or a sandwich board; Imitation natural stone 1 is made of concrete; the concrete is made of high-strength white cement mixed with epoxy resin and stone powder and gravel of various colors and particle sizes, and then added with water, high-efficiency water reducing agent and retarder.
