Description

Technical Field

[0001] The invention relates to the technical field of coatings, and 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 make coating products of various colors, greatly limiting the application of inorganic coatings in areas such as workshop pre-coating primers.

[0003] At present, the market demand for workshop pre-coating primer is becoming increasingly diversified, requiring it not only to have good anti-corrosion and anti-rust properties, but also to have a rich selection of colors to meet different decorative needs. However, traditional inorganic coatings cannot meet these requirements, which has brought certain troubles to the development of related industries.

[0004] Therefore, developing a thick paste 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 coating field. In view of this, a colorful thick paste inorganic workshop pre-coating primer 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 realize 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 thick paste type inorganic workshop pre-coating primer is composed of the following components: 35-40 parts by weight of water-based 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.

[0008] In a preferred embodiment, the composition comprises 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 comprises 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 comprises: 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 thick paste type inorganic workshop pre-coating primer comprises the following steps:

[0012] S1: 35-40 parts by weight of water-based 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: adding inorganic nano color paste and stirring evenly to obtain component A;

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

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

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

[0018] T2, grinding 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 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 the 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 thick paste type inorganic workshop pre-coating primer of the present invention has the following advantages:

[0026] First, from the perspective of color richness, traditional inorganic coatings are difficult to match with pigments due to the resin's own repulsiveness, resulting in a single color that cannot meet the diverse needs of workshop decoration and identification. 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 various colors of inorganic workshop pre-coating primers. This brings a brand new visual effect to the workshop environment, which not only improves the aesthetics of the workshop, but also allows for regional division and identification through different colors, facilitating production management and optimization of operating procedures. For example, different production areas, safety passages or dangerous areas can be marked with specific colors to improve work efficiency and safety.

[0027] Secondly, in terms of performance, the primer uses water-based inorganic resin as the main component and has excellent environmental performance. Compared with traditional organic solvent-based coatings, water-based inorganic coatings do not release a large amount of harmful volatile organic compounds (VOCs) during construction, reducing pollution to the environment and harm to the health of construction workers. At the same time, the inorganic resin has high stability and durability, and can maintain good performance in various harsh workshop environments, such as corrosion resistance, high temperature resistance, and wear resistance. This enables the primer to provide long-term and effective protection for workshop equipment and structures, extend their service life, and reduce maintenance costs.

[0028] Furthermore, the addition of zinc base material and functional filler further enhances the performance of the primer. Zinc base material has good anti-corrosion performance, which can effectively prevent corrosion of metal surfaces and provide reliable protection for metal equipment and structures in the workshop. Functional fillers can be selected and adjusted according to different needs, such as improving the hardness, wear resistance, adhesion, etc. of the coating. This flexible formula design can meet different workshop environments and usage 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 type 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 the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0033] Embodiment 1:

[0034] A method for preparing a multi-colored thick paste type 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: adding inorganic nano color paste and stirring evenly to obtain component A;

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

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

[0040] First, from the perspective of color richness, traditional inorganic coatings are difficult to match with pigments due to the resin's own repulsiveness, resulting in a single color that cannot meet the diverse needs of workshop decoration and identification. 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 various colors of inorganic workshop pre-coating primers. This brings a brand new visual effect to the workshop environment, which not only improves the aesthetics of the workshop, but also allows for regional division and identification through different colors, facilitating production management and optimization of operating procedures. For example, different production areas, safety passages or dangerous areas can be marked with specific colors to improve work efficiency and safety.

[0041] Secondly, in terms of performance, the primer uses water-based inorganic resin as the main component and has excellent environmental performance. Compared with traditional organic solvent-based coatings, water-based inorganic coatings do not release a large amount of harmful volatile organic compounds (VOCs) during construction, reducing pollution to the environment and harm to the health of construction workers. At the same time, the inorganic resin has high stability and durability, and can maintain good performance in various harsh workshop environments, such as corrosion resistance, high temperature resistance, and wear resistance. This enables the primer to provide long-term and effective protection for workshop equipment and structures, extend their service life, and reduce maintenance costs.

[0042] Furthermore, the addition of zinc base material and functional filler further enhances the performance of the primer. Zinc base material has good anti-corrosion performance, which can effectively prevent corrosion of metal surfaces and provide reliable protection for metal equipment and structures in the workshop. Functional fillers can be selected and adjusted according to different needs, such as improving the hardness, wear resistance, adhesion, etc. of the coating. This flexible formula design can meet different workshop environments and usage 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 type 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, grinding 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 inorganic nano color paste.

[0049] In the above steps, the specific weight ratio of inorganic nano pigments and deionized water is precisely controlled to ensure the rationality of the color paste composition and lay a good foundation for subsequent processes. The particle size of the inorganic nano pigment is controlled at 100-300nm through multiple grindings, 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 sufficient mixing can play a better role when applied to colorful thick paste type inorganic workshop pre-coating primer. The preparation process of colorless nano color paste is precise, which ensures the consistency of product quality and helps to improve the overall performance of the primer, such as color uniformity, glossiness, etc., and also provides a more reliable color foundation for workshop pre-coating primer.

[0050] Furthermore, the process of step T2 also 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, inorganic nano-pigments are etched by cubic boron nitride powder to make various rough surfaces appear on the surface of the pigment, greatly increasing the surface area of ​​the inorganic nano-pigments. This change significantly enhances the compatibility when combined with inorganic resins in the subsequent process. The rough surface provides more binding sites, allowing the inorganic nano-pigments to interact more closely with the inorganic resin, thereby ensuring the stability and uniformity of the color paste and the resin system. This helps to prepare a colorful, thick paste type inorganic workshop pre-coating primer with rich colors and stable quality, meeting the requirements of primer color and performance in different workshop environments.

[0054] On the other hand, during the grinding process, cubic boron nitride powder carves pits on the surface of inorganic nano-pigments and enters them. Although there will still be a trace amount of residue after vibration separation and centrifugal separation, this trace amount of cubic boron nitride powder has played a positive role in improving the hardness of the coating. In an industrial workshop environment, the primer needs to have a certain hardness to resist external forces such as wear and collision. The increase in hardness extends the service life of the primer, reduces maintenance costs, and provides more lasting protection for workshop equipment and structures. At the same time, the precise separation process ensures that the residual amount of cubic boron nitride powder is within a controllable range, will not have a negative impact on other properties of the primer, and ensures the balance and stability of the overall performance of the primer.

[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 inorganic nano-pigments. This precise etching further increases the surface area of ​​the pigment and improves compatibility with inorganic resins. When a colorful thick paste inorganic workshop pre-coating primer is subsequently prepared, it can ensure that the pigment and the 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, avoid adverse effects on the performance of the primer, and provide 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 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.

[0057] Under the above-mentioned step settings, on the one hand, the process progress can be accurately controlled. Through image comparison, it is possible to quickly determine whether the grinding and vibration separation processes are completed, avoiding the errors of traditional judgment methods, ensuring that production is carried out strictly in accordance with standards, and improving the stability and consistency of product quality. At the same time, based on the different colors of nano-inorganic pigments and cubic boron nitride in different combined states, image comparison can be used to more accurately identify the process status.

[0058] On the other hand, it helps to improve production efficiency. Timely grasp of process progress facilitates the reasonable arrangement of production processes, avoiding waste of resources and unnecessary waiting. If problems are found, they can be adjusted quickly to ensure the continuity and efficiency of production. Moreover, this image comparison based on color recognition provides an intuitive basis for quality control, which can timely discover potential problems such as uneven grinding and incomplete separation, take measures to improve them, further improve product quality, and provide a strong guarantee for the production of high-quality inorganic workshop pre-coating primers.

[0059] Embodiment 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] Embodiment three:

[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] Under the settings of the above embodiments, the weight ratio of inorganic nano pigment to deionized water is controlled at 4:5-9:10, and grinding is performed three to four times. After testing, the color paste prepared by the traditional method has a larger particle size and poor compatibility with the water-based inorganic resin; while the color paste prepared by the new technology has a particle size between 100-300nm and good compatibility with the water-based inorganic resin.

[0064] In the cubic boron nitride etching and separation effect experiment, the traditional method did not use cubic boron nitride. After adopting the new technology solution, cubic boron nitride with a particle size of 40-50nm was used to etch the inorganic nano pigment. The surface area of ​​the pigment increased by 30%-40%, making it more compatible with the subsequent combination with the inorganic resin. At the same time, the hardness of the coating increased by 20%-30%. And after centrifugal separation, the residual cubic boron nitride is extremely small and does not affect the performance of the coating.

[0065] The traditional method does not use image comparison, and the accuracy of process judgment is only 70%, production efficiency has not been significantly improved, and quality problems are discovered late. After adopting the new technology solution, by taking powder images and comparing them with model images, the accuracy of process judgment can reach 95%, production efficiency can be improved by 25%-30%, and quality problems can be discovered in time, providing a strong guarantee for product quality.
