Description

Technical Field

[0001] The invention relates to the technical field of artificial stone product production, and in particular to a high-performance vortex-textured artificial stone and a production process thereof. Background Art

[0002] As a kind of geometric pattern, vortex texture is one of the earliest patterns created and used in the history of human decoration. It is still full of vitality and widely used. This unique texture is not only full of artistic beauty, but also can show a unique decorative effect in artificial stone. With the continuous changes and improvement of market demand, the development of artificial stone texture has gone through a process from simple imitation to high simulation. Technological progress and changes in market demand have promoted its continuous progress and innovation. At present, both domestic and foreign research on vortex texture artificial stone has made certain progress.

[0003] In China, the research and application of vortex textures in the artificial stone industry are increasing. Some companies have begun to explore the combination of traditional vortex patterns and modern artificial stone technology to create new artificial stones with national characteristics and artistic value. For example, artificial granite products in Shuitou, Fujian, Yunfu, Guangdong and other regions have incorporated vortex texture designs, making the products not only beautiful in appearance, but also contain profound cultural connotations. These products are widely used in architectural decoration, furniture manufacturing, kitchen countertops and other fields, and have been widely praised by the market.

[0004] Internationally, the research on vortex texture artificial stone has also attracted much attention. Artificial stone companies in Europe and the United States have achieved remarkable results in the design and manufacture of vortex textures with advanced technology and equipment. Through advanced digital design and processing technology, they can accurately control the shape, color and distribution of the texture, making the decorative effect of artificial stone more realistic and delicate. For example, some high-end artificial quartz products not only have vortex textures, but also incorporate various elements such as metal texture and glass texture, making the products more diversified and personalized.

[0005] However, although certain achievements have been made in the research of vortex texture artificial stone at home and abroad, there are still some problems.

[0006] First, the technical difficulties have not been completely solved. In the production process of artificial stone, how to accurately control the shape, color and distribution of the texture is still a technical problem. At present, although some advanced technologies and equipment have been applied to the production of artificial stone, the fineness and realism of the texture still need to be improved.

[0007] Secondly, the market application is limited. Due to the relatively high production cost of vortex texture artificial stone, its market application is limited to a certain extent. In some high-end markets and special occasions, such as luxury residences, hotels and art exhibitions, vortex texture artificial stone is widely used; but in some mid- and low-end markets and ordinary occasions, its application is relatively small.

[0008] In summary, some progress has been made in the research of vortex texture artificial stone at home and abroad, but there are still challenges such as technical difficulties and market application restrictions. In order to promote the further development and application of vortex texture artificial stone, it is necessary to increase research and development efforts and improve the technical level; at the same time, it is also necessary to pay attention to market demand and environmental protection requirements to promote the sustainable development of the artificial stone industry. Summary of the invention

[0009] In view of the insufficiency of existing research on the above-mentioned topics, the present invention provides a high-performance vortex texture artificial stone and a production process thereof. The product of the present invention can well make up for the shortcomings of ordinary artificial stone and natural stone, meet the decoration needs, and has a very high cost performance.

[0010] In order to achieve the above objectives, the present invention provides the following technical solutions:

[0027] The present invention also provides a production process of vortex texture artificial stone, comprising the following steps:

[0028] (1) Weigh the calcium carbonate powder, unsaturated polyester resin, curing agent, accelerator, auxiliary agent, mixed pigment, and powdered pigment according to the proportion;

[0029] (2) putting the weighed calcium carbonate powder, mixed pigment, and auxiliary agent components in step (1) into a blender, stirring the materials, and then using high-speed beating to obtain a mixture;

[0033] Compared with the prior art, the technical advantages of the present invention are not only significant, but also have achieved breakthrough progress in multiple dimensions, which are specifically manifested in the following aspects:

[0034] (1) In terms of innovation in manufacturing technology, the present invention pioneered the use of a coiled rod with a rough surface. A major highlight of this coiled rod is that it can accurately control the diameter of the rod through inflation. This feature allows the material to be more flexibly adapted to different production needs after being pressed into sheets by a double-roller machine. What is even more striking is that the present invention sprinkles color powder on the surface of the material after sheeting, which not only adds color layers to the material, but also lays a solid foundation for subsequent production steps. Subsequently, these carefully processed materials are rolled up to form rods, and further formed through vacuum pressing technology, and finally spiral textured artificial stones are produced. This innovation not only greatly enriches the texture types of artificial stone products, but also brings a new visual experience to the market, meeting consumers' urgent needs for diversified and personalized decorative materials.

[0035] (2) In terms of product quality and price, the artificial stone products produced by the present invention show natural, delicate and colorful characteristics by virtue of their unique vortex texture. These textures are not only beautiful and elegant, but also can be well integrated into various interior decoration styles, adding a unique artistic atmosphere to the home environment. More importantly, although these products are not inferior to high-end stone in visual effects, their prices are similar to the price range of ordinary artificial stones (more than 30-200 yuan / square meter), which is much lower than the expensive price of natural marble (more than 200-20,000 yuan / square meter). This cost-effectiveness advantage makes the products of the present invention more affordable, allowing more consumers to enjoy the high-quality stone decoration effect, and also brings new development opportunities to the artificial stone industry.

[0036] (3) The present invention also performs well in terms of safety. After strict testing, the radioactivity index of the vortex texture artificial stone of the present invention is Ra and I rAll of them are lower than 0.1, reaching the highest standard of Class A decoration materials, and fully complying with the relevant provisions of GB6566-2010 Limits of Radioactive Nuclides in Building Materials. This test result not only proves the excellent performance of the product of the present invention in environmental protection, but also demonstrates its firm commitment to protecting the health of consumers.

[0037] (4) In terms of filling the gap in the market, the emergence of the product of the present invention is undoubtedly a powerful supplement to the defects of ordinary artificial stone and natural stone. It has the price advantage of ordinary artificial stone, the texture beauty of natural stone, and avoids the shortcomings of natural stone such as fragility and high price. This product characteristic with multiple advantages makes the present invention highly competitive in the decoration market and can meet consumers' needs for beauty, practicality, economy and other aspects.

[0038] In summary, the technical advantages of the present invention are not only reflected in the innovation of the manufacturing process, but also in the significant improvements in many aspects such as product quality, price advantage, safety and market adaptability.

After 120 seconds, the pressure head is opened to press for 160 seconds to form the artificial stone. The artificial stone is subsequently processed to obtain a vortex texture artificial stone product.

[0062] Technical principle of the present invention:

[0063] 1. The specific role of each raw material in the preparation process of vortex texture artificial stone

[0064] 1. Calcium carbonate powder

[0065] As the main filling material, it provides the main structure and volume of artificial stone. The calcium carbonate powder with a weight fraction of 100% pure powder material ensures the purity and stability of artificial stone.

[0066] Its high content gives artificial stone a certain hardness and strength, while also reducing costs.

[0067] 2. Unsaturated polyester resin

[0068] As a binder, various raw materials such as calcium carbonate powder are bonded together to form a solid artificial stone structure.

[0069] The dosage is 9-15% of the weight of calcium carbonate powder. This ratio can ensure sufficient bonding without causing too much resin to affect the performance of artificial stone. The right amount of resin can give artificial stone good mechanical properties and chemical corrosion resistance.

[0070] 3. Curing agent

[0071] It reacts chemically with unsaturated polyester resin to solidify the resin, thereby forming the artificial stone.

[0072] The dosage of curing agent is 1-2.5% of the weight of unsaturated polyester resin. This ratio can ensure that the resin is cured within a suitable time and avoid the adverse effects caused by too fast or too slow curing.

[0073] 4. Accelerator

[0074] Accelerate the reaction rate of unsaturated polyester resin and curing agent, shorten the curing time of artificial stone.

[0075] The dosage of the accelerator is 0.1-0.5% of the weight of the unsaturated polyester resin. An appropriate amount of the accelerator can improve production efficiency without having a negative impact on the performance of the artificial stone.

[0076] 5. Additives

[0077] It includes wetting agent, thickener and dispersant. Each component works synergistically to ensure the dispersion effect of the material, control the amount of resin and the molding effect of the long strip material.

[0078] (1) Wetting agent: such as 9100 wetting agent, PVA wetting agent, VE wetting agent, silicone wetting agent, etc., the usage ratio is 0.7-1.5% of the weight of the raw material. The function of the wetting agent is to reduce the surface tension of the material, so that the resin can better wet the particles such as calcium carbonate powder, and improve the dispersion and uniformity of the material.

[0079] (2) Thickener: such as rheological thickener NP-605A, calcium ozone, non-ionic polyether polyurethane thickener, etc., the usage ratio is 0.1-0.5% of the weight of the raw material. The function of the thickener is to increase the viscosity of the material, prevent the material from stratification and precipitation during the production process, and also help control the amount of resin.

[0080] (3) Dispersants: such as polyethylene glycol, polyethylene glycol sorbate, polyoxyethylene alcohol, BASF PU4046 dispersant, etc., the use ratio is 0.2-1.5% of the weight of the raw material. The function of the dispersant is to evenly disperse various pigments and fillers in the resin to avoid agglomeration and improve the color uniformity and appearance quality of the artificial stone.

[0081] 6. Mixing pigments

[0082] It includes one or more of ultramarine blue, phthalocyanine blue, titanium dioxide, iron black, orange yellow, iron red, etc., and the dosage is 0.03-0.09% of the weight of calcium carbonate powder. The role of mixed pigments is to give artificial stone a specific color and tone to meet the needs of different customers.

[0083] 7. Powder coating

[0084] It is composed of 90-mesh sand, titanium dioxide, aluminum powder, and iron-based pigments, and the weight accounts for 0.05-0.1% of the total raw material weight. Among them, the amount of 90-mesh sand is 0.02-0.033%, the amount of titanium dioxide is 0.013-0.024%, the amount of aluminum powder is 0.010-0.025%, and the amount of iron-based pigments is 0.007-0.018%. Iron-based pigments include one or more of iron yellow, iron green, and iron red. The function of the powder-coated pigment is to form a unique vortex texture on the surface of the artificial stone, which increases the beauty and decorativeness of the artificial stone.

[0085] 2. The synergistic effect between the raw materials improves the performance of vortex texture artificial stone and achieves unexpected technical effects

[0086] 1. Synergistic effect of calcium carbonate powder and unsaturated polyester resin

[0087] Calcium carbonate powder acts as a filler material, providing support and strength to the unsaturated polyester resin. The resin binds the calcium carbonate powder together to form a solid artificial stone structure. The ratio of the two is carefully optimized to ensure the hardness, strength and durability of the artificial stone.

[0088] At the same time, the high content of calcium carbonate powder can reduce the cost of artificial stone, while the bonding effect of resin ensures the performance and quality of artificial stone.

[0089] 2. Synergistic effect of each component of the additive

[0090] Wetting agents, thickeners and dispersants work together to play a role. Wetting agents reduce the surface tension of materials, allowing resins to better wet calcium carbonate powder and other particles, improving the dispersion and uniformity of materials. Thickeners increase the viscosity of materials to prevent material stratification and precipitation, and also help control the amount of resin. Dispersants make various pigments and fillers evenly dispersed in the resin to avoid agglomeration, improving the color uniformity and appearance quality of artificial stone.

[0091] The synergistic effect of the various components of the additives can improve the production efficiency and quality of artificial stone, and at the same time reduce production costs. For example, by controlling the amount of resin used, the waste of resin can be reduced and the cost can be reduced. At the same time, a good dispersion effect can improve the color uniformity and appearance quality of artificial stone, and increase the market competitiveness of the product.

[0092] 3. Synergistic effect of mixed pigments and powdered pigments

[0093] The mixed pigments give the artificial stone a specific color and tone inside, while the powdered pigments form a unique vortex texture on the surface of the artificial stone. The two work together to give the artificial stone a more beautiful and decorative appearance.

[0094] The ratio of 90-mesh sand, titanium dioxide, aluminum powder and iron pigments in the powder coating pigment has been carefully optimized to form a clear and beautiful vortex texture. At the same time, the colors of these pigments and the mixed pigments are coordinated to make the overall appearance of the artificial stone more harmonious and beautiful.

[0095] 4. Overall synergy between raw materials

[0096] All raw materials work together in the preparation process, from the bonding of calcium carbonate powder and resin, to the dispersion and thickening of additives, to the coloring of pigments and the formation of textures, each link is closely connected.

[0097] This overall synergy makes the vortex texture artificial stone have excellent performance and beautiful appearance. For example, the good dispersion effect can improve the mechanical properties and chemical corrosion resistance of artificial stone, while the unique vortex texture increases the decorativeness and market competitiveness of artificial stone.

[0098] 3. The necessity and importance of controlling the amount of each raw material and optimizing the process parameters in the preparation process of vortex texture artificial stone, as well as the unexpected technical effects achieved

[0099] 1. The necessity and importance of controlling the amount of raw materials

[0100] The amount of each raw material directly affects the performance and quality of artificial stone. For example, too much unsaturated polyester resin will make the artificial stone too soft and reduce its strength; too little will make it difficult to shape and have poor adhesion. The amount of curing agent and accelerator also needs to be strictly controlled to ensure that the resin cures within the appropriate time and avoid the adverse effects of too fast or too slow curing.

[0101] The amount of additives also needs to be adjusted according to the actual situation to ensure the dispersion effect of the material, control the amount of resin and the molding effect of the long strip material. The amount of mixed pigment and powder coating pigment determines the color and texture of the artificial stone, which needs to be precisely controlled according to customer needs.

[0102] By precisely controlling the amount of each raw material, the performance and quality of artificial stone can be optimized and the market competitiveness of the product can be improved.

[0103] 2. Necessity and importance of process parameter optimization

[0104] Process parameters such as stirring speed, stirring time, roller spacing, pressing time and pressure also have an important impact on the performance and quality of artificial stone. For example, low-speed stirring can avoid material splashing and agglomeration, while high-speed stirring can fully break up the materials and evenly combine them. Adjusting the roller spacing can control the thickness and shape of the material, while pressing time and pressure determine the density and strength of the artificial stone.

[0105] By optimizing the process parameters, the production efficiency and quality of artificial stone can be improved, and the production cost can also be reduced. For example, reasonable stirring speed and time can reduce energy consumption and improve production efficiency. Appropriate pressing time and pressure can ensure the density and strength of artificial stone and reduce the scrap rate.

[0106] 3. Unexpected technical effects achieved

[0107] By precisely controlling the amount of each raw material and optimizing the process parameters, the vortex texture artificial stone preparation process can achieve unexpected technical effects. For example, it can achieve a high degree of uniformity in color and texture of artificial stone, improving the aesthetics and decorativeness of the product. At the same time, good mechanical properties and chemical corrosion resistance can enable artificial stone to be used for a long time in various environments, increasing the service life of the product.

[0108] In addition, the optimized process can also improve production efficiency, reduce production costs, and bring greater economic benefits to the enterprise. For example, reasonable stirring speed and time can reduce energy consumption and improve production efficiency. Accurately controlling the amount of resin can reduce resin waste and reduce costs.

[0109] In summary, the specific role of each raw material in the vortex texture artificial stone preparation process of the present invention, the synergistic effect, the necessity and importance of controlling the amount of raw materials and optimizing the process parameters are very important. Through careful design and optimization, a vortex texture artificial stone product with excellent performance and beautiful appearance can be prepared to meet the needs of the market.
