Description

Technical Field

[0001] The invention relates to the technical field of coatings, in particular to a multi-colored thick paste type inorganic workshop pre-coating primer and a preparation method thereof. Background Art

[0002] Traditional inorganic coatings cannot match well with pigments due to the resin's own repellency, which makes the color selection of inorganic coatings very limited and difficult to produce coating products of various colors, greatly restricting the application of inorganic coatings in areas such as workshop pre-coating primers.

[0003] Market demands for workshop pre-coating primers are becoming increasingly diverse, requiring not only excellent corrosion and rust resistance but also a wide range of color options to meet diverse decorative needs. However, traditional inorganic coatings are unable to meet these requirements, creating challenges for the development of related industries.

[0004] Therefore, developing a high-build inorganic workshop pre-coating primer that can overcome the defects of traditional inorganic coatings and achieve colorful and excellent performance has become an urgent problem to be solved in the current coatings field. In view of this, a high-build inorganic workshop pre-coating primer with colorful colors and a preparation method are proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a colorful thick paste type inorganic workshop pre-coating primer and a preparation method thereof, which can achieve the realization of rich colors.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A multi-colored, high-paste inorganic workshop pre-coating primer comprises the following ingredients: 35-40 parts by weight of a water-based inorganic resin, 25-35 parts by weight of a zinc base material, 5-10 parts by weight of an inorganic nano-color paste, 25-35 parts by weight of a functional filler, 0.5-1 part by weight of a dispersant, 0.2-0.5 part by weight of a defoamer, and 0.5-1 part by weight of a wetting agent.

[0008] In a preferred embodiment, the composition is composed of the following ingredients: 35 parts by weight of aqueous inorganic resin, 25 parts by weight of zinc base material, 5 parts by weight of inorganic nano-color paste, 25 parts by weight of functional filler, 0.5 parts by weight of dispersant, 0.2 parts by weight of defoamer and 0.5 parts by weight of wetting agent.

[0009] In a preferred embodiment, the composition is composed of the following ingredients: 40 parts by weight of aqueous inorganic resin, 35 parts by weight of zinc base material, 10 parts by weight of inorganic nano-color paste, 35 parts by weight of functional filler, 1 part by weight of dispersant, 0.5 parts by weight of defoamer and 1 part by weight of wetting agent.

[0010] In a preferred embodiment, the composition is composed of the following ingredients: 37 parts by weight of aqueous inorganic resin, 30 parts by weight of zinc base material, 8 parts by weight of inorganic nano-color paste, 30 parts by weight of functional filler, 0.8 parts by weight of dispersant, 0.3 parts by weight of defoamer and 0.8 parts by weight of wetting agent.

[0011] A method for preparing a multi-colored, high-build inorganic workshop pre-coating primer comprises the following steps:

[0012] S1: 35-40 parts by weight of waterborne inorganic resin, 25-35 parts by weight of zinc base material, 5-10 parts by weight of inorganic nano-color paste, 25-35 parts by weight of functional filler, 0.5-1 part by weight of dispersant, 0.2-0.5 part by weight of defoamer and 0.5-1 part by weight of wetting agent;

[0013] S2: Add water-based inorganic resin, dispersant, defoamer and wetting agent into a stirring device for preliminary stirring;

[0014] S3: Add inorganic nano-color paste and stir evenly to prepare component A;

[0015] S4: Add zinc base material and functional filler to component A, stirring while adding, and finally stir evenly to obtain the finished product.

[0016] In a preferred embodiment, the steps of preparing the inorganic nano-color paste include:

[0017] T1. Take inorganic nano pigment and deionized water, the weight ratio of inorganic nano pigment to deionized water is 4:5-9:10;

[0018] T2. Grind the inorganic nano-pigment three to four times until the particle size is 100-300 nm;

[0019] T3. Fully mix the ground inorganic nano pigment and deionized water to prepare an inorganic nano color paste.

[0020] In a preferred embodiment, the process of step T2 further includes:

[0021] The ground inorganic nano-pigment is mixed with cubic boron nitride powder, and the mixed powder is ground. After grinding, the inorganic nano-pigment and cubic boron nitride powder are centrifugally separated.

[0022] In a preferred embodiment, the particle size of the cubic boron nitride powder is 40-50 nm.

[0023] In a preferred embodiment, before centrifuging the mixed powder of the inorganic nanomaterial and cubic boron nitride powder, the mixed powder is placed on a vibrating plate for vibration separation.

[0024] In a preferred embodiment, during the process of grinding the mixed powder and vibrating and separating the mixed powder, a powder image is taken, and the powder image obtained by the photograph is compared with the model image. When the model comparison results match, it indicates that the step is executed in place.

[0025] Compared with the prior art, the multi-colored high-build inorganic workshop pre-coating primer of the present invention has the following advantages:

[0026] First, in terms of color richness, traditional inorganic coatings are difficult to match with pigments due to the inherent repulsiveness of the resin, resulting in a monotonous color that cannot meet the diverse needs of workshop decoration and signage. However, the present invention successfully achieves compatibility with water-based inorganic resins by preferentially prefabricating inorganic nano-color pastes, allowing inorganic coatings to be made into inorganic workshop pre-coating primers of various colors. This brings a refreshing visual effect to the workshop environment, not only improving the aesthetics of the workshop, but also allowing for area division and identification through different colors, facilitating production management and optimizing operational processes. For example, different production areas, safety passages, or hazardous areas can be marked with specific colors, improving work efficiency and safety.

[0027] Secondly, in terms of performance, this primer uses a water-based inorganic resin as its primary ingredient, resulting in excellent environmental performance. Compared to traditional organic solvent-based coatings, water-based inorganic coatings do not release large amounts of harmful volatile organic compounds (VOCs) during application, reducing environmental pollution and health hazards to construction workers. Furthermore, the inorganic resin's high stability and durability enable it to maintain excellent performance in various harsh workshop environments, such as corrosion resistance, high temperature resistance, and wear resistance. This enables the primer to provide long-term, effective protection for workshop equipment and structures, extending their service life and reducing maintenance costs.

[0028] Furthermore, the addition of a zinc base and functional fillers further enhances the primer's performance. The zinc base offers excellent corrosion resistance, effectively preventing corrosion on metal surfaces and providing reliable protection for metal equipment and structures within the workshop. Functional fillers can be selected and adjusted to meet specific requirements, such as enhancing the coating's hardness, wear resistance, and adhesion. This flexible formulation design can meet diverse workshop environments and application requirements, providing users with personalized solutions.

[0029] In addition, the preparation method is simple and easy, has high operability and production efficiency, can ensure that each component is fully and evenly dispersed in the coating system, and ensures the quality stability of the primer.

[0030] In short, this colorful thick paste inorganic workshop pre-coating primer and preparation method have many beneficial effects such as rich colors, good environmental performance, excellent performance, simple preparation method, etc. DETAILED DESCRIPTION

[0031] The present invention is described in further detail below.

[0032] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0033] Example 1:

[0034] A method for preparing a multi-colored, high-build inorganic workshop pre-coating primer comprises the following steps:

[0035] S1: 35 parts by weight of water-based inorganic resin, 25 parts by weight of zinc base material, 5 parts by weight of inorganic nano-color paste, 25 parts by weight of functional filler, 0.5 parts by weight of dispersant, 0.2 parts by weight of defoamer and 0.5 parts by weight of wetting agent;

[0036] S2: Add water-based inorganic resin, dispersant, defoamer and wetting agent into a stirring device for preliminary stirring;

[0037] S3: Add inorganic nano-color paste and stir evenly to prepare component A;

[0038] S4: Add zinc base material and functional filler to component A, stirring while adding, and finally stir evenly to obtain the finished product.

[0039] The multi-colored, high-build inorganic workshop pre-coating primer prepared in this embodiment has the following advantages:

[0040] First, in terms of color richness, traditional inorganic coatings are difficult to match with pigments due to the inherent repulsiveness of the resin, resulting in a monotonous color that cannot meet the diverse needs of workshop decoration and signage. However, the present invention successfully achieves compatibility with water-based inorganic resins by preferentially prefabricating inorganic nano-color pastes, allowing inorganic coatings to be made into inorganic workshop pre-coating primers of various colors. This brings a refreshing visual effect to the workshop environment, not only improving the aesthetics of the workshop, but also allowing for area division and identification through different colors, facilitating production management and optimizing operational processes. For example, different production areas, safety passages, or hazardous areas can be marked with specific colors, improving work efficiency and safety.

[0041] Secondly, in terms of performance, this primer uses a water-based inorganic resin as its primary ingredient, resulting in excellent environmental performance. Compared to traditional organic solvent-based coatings, water-based inorganic coatings do not release large amounts of harmful volatile organic compounds (VOCs) during application, reducing environmental pollution and health hazards to construction workers. Furthermore, the inorganic resin's high stability and durability enable it to maintain excellent performance in various harsh workshop environments, such as corrosion resistance, high temperature resistance, and wear resistance. This enables the primer to provide long-term, effective protection for workshop equipment and structures, extending their service life and reducing maintenance costs.

[0042] Furthermore, the addition of a zinc base and functional fillers further enhances the primer's performance. The zinc base offers excellent corrosion resistance, effectively preventing corrosion on metal surfaces and providing reliable protection for metal equipment and structures within the workshop. Functional fillers can be selected and adjusted to meet specific requirements, such as enhancing the coating's hardness, wear resistance, and adhesion. This flexible formulation design can meet diverse workshop environments and application requirements, providing users with personalized solutions.

[0043] In addition, the preparation method is simple and easy, has high operability and production efficiency, can ensure that each component is fully and evenly dispersed in the coating system, and ensures the quality stability of the primer.

[0044] In short, this colorful thick paste inorganic workshop pre-coating primer and preparation method have many beneficial effects such as rich colors, good environmental performance, excellent performance, simple preparation method, etc.

[0045] Furthermore, the preparation steps of the inorganic nano-color paste include:

[0046] T1, taking inorganic nano pigment and deionized water, the weight ratio of inorganic nano pigment to deionized water is 4:, 5-9:10;

[0047] T2. Grind the inorganic nano-pigment three to four times until the particle size is 100-300 nm;

[0048] T3. Fully mix the ground inorganic nano pigment and deionized water to prepare an inorganic nano color paste.

[0049] In the above steps, the specific weight ratio of inorganic nano-pigment and deionized water is precisely controlled to ensure the rationality of the color paste composition and lay a good foundation for subsequent processes. Through multiple grinding, the particle size of the inorganic nano-pigment is controlled at 100-300nm, making the color paste particles more delicate and uniform, and enhancing the compatibility and stability with water-based inorganic resins. The inorganic nano-color paste obtained after thorough mixing can better play its role when applied to colorful thick-paste inorganic workshop pre-coating primers. The preparation process of colorless nano-color paste is precise, ensuring the consistency of product quality, helping to improve the overall performance of the primer, such as color uniformity and glossiness, while also providing a more reliable color foundation for workshop pre-coating primers.

[0050] Furthermore, the process of step T2 further includes:

[0051] The ground inorganic nano-pigment is mixed with cubic boron nitride powder, and the mixed powder is ground. After grinding, the inorganic nano-pigment and cubic boron nitride powder are centrifugally separated.

[0052] Furthermore, before centrifuging the mixed powder of the inorganic nanomaterial and the cubic boron nitride powder, the mixed powder is placed on a vibrating plate for vibration separation.

[0053] Under the above steps, on the one hand, the inorganic nanopigment is etched with cubic boron nitride powder, resulting in various rough surfaces on the pigment surface, greatly increasing the surface area of ​​the inorganic nanopigment. This change significantly enhances compatibility when subsequently combined with inorganic resins. The rough surface provides more binding sites, allowing the inorganic nanopigment to interact more closely with the inorganic resin, thereby ensuring the stability and uniformity of the color paste and resin system. This helps to produce a rich, colorful, high-paste inorganic workshop pre-coat primer with stable quality, meeting the primer color and performance requirements of different workshop environments.

[0054] During the grinding process, the CBN powder carves pits into the surface of the inorganic nanopigment and penetrates into it. Although a trace amount of CBN powder remains after vibration separation and centrifugation, this trace amount of CBN powder has a positive effect on improving the hardness of the coating. In industrial workshop environments, primers require a certain hardness to withstand external forces such as wear and collision. This increased hardness extends the primer's service life, reduces maintenance costs, and provides longer-lasting protection for workshop equipment and structures. Furthermore, the precise separation process ensures that the residual amount of CBN powder remains within a controllable range, without negatively impacting other properties of the primer, thereby ensuring the overall balance and stability of the primer's performance.

[0055] Furthermore, the particle size of the cubic boron nitride powder is 40-50nm. The smaller particle size enables it to accurately form pits on the surface of the inorganic nano-pigment. This precise etching further increases the surface area of ​​the pigment and improves its compatibility with inorganic resins. When subsequently preparing a colorful, thick-paste inorganic workshop pre-coat primer, it can ensure that the pigment and resin are fully combined, making the color of the primer more uniform and stable. At the same time, the appropriate pit size helps to better control the residual amount of cubic boron nitride powder during the grinding process, avoiding adverse effects on the primer performance and providing a strong guarantee for the high quality of the primer.

[0056] Furthermore, during the process of grinding the mixed powder and vibrating and separating the mixed powder, a powder image is captured, and the captured powder image is compared with the model image. When the model comparison results match, it indicates that the step has been performed successfully.

[0057] The above-mentioned steps enable precise control of process progress. Image comparison allows for rapid determination of the completion of the grinding and vibration separation processes, avoiding errors associated with traditional methods. This ensures strict adherence to production standards and improves product quality stability and consistency. Furthermore, image comparison allows for more precise identification of process status based on the distinct colors exhibited by the nano-inorganic pigments and cubic boron nitride in varying states of bonding.

[0058] On the other hand, it helps improve production efficiency. Keeping track of process progress facilitates optimal production flow, avoiding wasted resources and unnecessary waiting. If problems are discovered, adjustments can be made quickly to ensure continuous and efficient production. Furthermore, this color-recognition-based image comparison provides an intuitive basis for quality control, enabling timely identification of potential issues such as uneven grinding and incomplete separation. Corrective measures can then be taken to further enhance product quality, providing a strong guarantee for the production of high-quality inorganic pre-coat primers.

[0059] Example 2:

[0060] The difference from Example 1 is that the proportions in step S1 are as follows: 35 parts by weight of aqueous inorganic resin, 25 parts by weight of zinc base material, 5 parts by weight of inorganic nano-color paste, 25 parts by weight of functional filler, 0.5 parts by weight of dispersant, 0.2 parts by weight of defoamer and 0.5 parts by weight of wetting agent.

[0061] Example 3:

[0062] The difference from Example 1 is that the proportions in step S1 are as follows: 37 parts by weight of aqueous inorganic resin, 30 parts by weight of zinc base material, 8 parts by weight of inorganic nano-color paste, 30 parts by weight of functional filler, 0.8 parts by weight of dispersant, 0.3 parts by weight of defoamer and 0.8 parts by weight of wetting agent.

[0063] In the above examples, the weight ratio of inorganic nanopigment to deionized water was controlled between 4:5 and 9:10, and grinding was performed three to four times. Testing revealed that the color paste prepared using the traditional method had a larger particle size and poor compatibility with the water-based inorganic resin. However, the color paste prepared using the new technology had a particle size between 100 and 300 nm and exhibited good compatibility with the water-based inorganic resin.

[0064] In experiments on the etching and separation effects of cubic boron nitride, conventional methods do not utilize cubic boron nitride. However, the new technology employed cubic boron nitride with a particle size of 40-50 nm to etch inorganic nanopigments. This increased the pigment's surface area by 30%-40%, improving compatibility with subsequent inorganic resins. Furthermore, the coating's hardness increased by 20%-30%. Furthermore, after centrifugation, the residual cubic boron nitride was minimal and did not affect the coating's performance.

[0065] Traditional methods, which don't use image comparison, have a process judgment accuracy rate of only 70%, resulting in no significant improvement in production efficiency and late detection of quality issues. However, with this new technology, which captures powder images and compares them with model images, the process judgment accuracy rate reaches 95%, improving production efficiency by 25%-30%. This allows for timely detection of quality issues, providing a strong guarantee for product quality.
