Description

Technical Field

[0001] The invention relates to the technical field of safety assessment of power systems, and in particular to a high-adhesion water-based wood sealing primer. Background Art

[0002] In the field of wood coatings, the adhesion of primer is crucial to the performance of the entire coating system. Traditional primers have problems such as insufficient adhesion and easy cracking, which affect the appearance and service life of wood.

[0003] Existing technologies in the field of wood coatings have certain limitations. Traditional primers lack adhesion, which can easily cause the coating to fall off, affecting the aesthetics and protective effects of the wood. For example, in humid environments, primers with poor adhesion easily absorb moisture, causing the coating to bubble and peel, shortening the service life of the wood. Traditional primers are also prone to cracking. After the coating is formed, as the wood naturally shrinks or the ambient temperature and humidity change, the primer's lack of flexibility causes cracks to form. These cracks can penetrate moisture and air, further corroding the wood and reducing the durability of the wood. Furthermore, traditional primers have poor construction adaptability and demanding requirements for the construction environment. Even slight changes in humidity and temperature can affect the coating quality. In high-temperature and high-humidity environments, the primer dries too quickly, easily resulting in surface defects. In low-temperature and low-humidity conditions, the drying time is prolonged, affecting production efficiency. These problems with existing technologies highlight the need for innovative solutions to overcome the bottlenecks of traditional primers in adhesion, crack resistance, and construction adaptability, and to promote the advancement of wood coating technology. Summary of the Invention

[0004] The main purpose of the present invention is to provide a high-adhesion water-based wood sealing primer, which can effectively solve the problems of insufficient adhesion and easy cracking of traditional primers.

[0005] To achieve the above object, the technical solution adopted by the present invention is: a high-adhesion water-based wood sealing primer, the method comprising the following steps:

[0006] S1. Raw material selection and preparation: Select water-based resin with a solid content of 30%-50%; pigment fineness ≤15 microns; filler ratio of 10%-30%;

[0007] S2. Primer preparation: Add the treated raw materials into the dispersion equipment in proportion, with a dispersion speed of 1000-2000 rpm, a dispersion time of 10-30 minutes, and a dispersion temperature of 20-30 degrees Celsius to form a uniform and stable primer slurry;

[0008] S3. Primer preparation: According to the wood type and surface condition, adjust the primer viscosity to 50-150 seconds, control the drying time to 30-60 minutes, and adjust the hardness to 0.5-1.5;

[0009] S4. Construction application: Use processes including spraying, brushing and dipping to evenly apply the prepared primer on the wood surface. The spraying pressure is 0.3-0.6 MPa, the paint film thickness is 50-100 microns, and the construction environment humidity is 40%-60%;

[0010] S5. Drying and curing: Place the primer-coated wood in a dry environment and dry it at room temperature for 2-4 hours. If heated and dried, the temperature should be 40-60 degrees Celsius and the drying time should be 30-60 minutes. UV curing can also be used.

[0011] Preferably, in step S3, nanomaterials are added, and the nanomaterials are nano titanium dioxide and nano zinc oxide, and the addition amount is 0.5%-3% of the total weight of the primer. The nanomaterial dispersion step adopts a high-speed dispersion equipment, the dispersion time is 30-60 minutes, and the dispersion speed is 1500-2500 rpm.

[0012] Preferably, the preparation method also includes using an intelligent monitoring and feedback system to monitor and control the primer preparation and construction process. The intelligent monitoring and feedback system includes real-time monitoring equipment and a control system. The real-time monitoring equipment is used to monitor parameters such as paint film drying speed, thickness, adhesion, etc. The monitoring accuracy is ±1%, the temperature monitoring range is 10-80 degrees Celsius, and the humidity monitoring range is 20%-90%. The control system automatically adjusts the primer formula and construction process parameters according to the feedback information.

[0013] Preferably, the preparation method further comprises using bio-based materials in step S1, wherein the bio-based materials are bio-based plasticizers and bio-based resins, and the replacement ratio thereof is 10%-30%, and the pretreatment temperature of the bio-based materials is 40-60 degrees Celsius, and the pretreatment time is 1-3 hours.

[0014] Preferably, the water-based resin is acrylic emulsion or polyurethane emulsion.

[0016] Preferably, the filler is talc or calcium carbonate.

[0017] Preferably, the storage stability of the primer is 6-12 months.

[0018] Preferably, the adhesion of the primer is level 1-3, and the production cycle of the primer is 4-8 hours.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, during the raw material selection and preparation phase, a water-based resin with a solids content of 30%-50% is carefully selected, combined with a pigment with a fineness of no more than 15 microns and a filler content of 10%-30%, laying a solid foundation for the high performance of the primer. During the primer preparation process, the dispersion speed is strictly controlled at 1000-2000 rpm, the dispersion time is maintained at 10-30 minutes, and the dispersion temperature is maintained at 20-30 degrees Celsius. This parameter combination allows the raw materials to fully blend, forming a uniform and stable primer slurry, effectively improving the stability and consistency of the primer. During the primer mixing stage, the primer viscosity is precisely controlled to 50-150 seconds, the drying time is controlled at 30-60 minutes, and the hardness is adjusted to an appropriate range of 0.5-1.5, depending on the specific wood type and surface condition. This refined mixing allows the primer to better adapt to the characteristics of different wood types, thereby significantly enhancing the compatibility between the primer and the wood, laying a solid foundation for subsequent construction.

[0021] 2. In the present invention, the method innovatively utilizes multiple application techniques, including spraying, brushing, and dipping, combined with precisely controlled spray pressures of 0.3-0.6 MPa, a film thickness of 50-100 microns, and a construction humidity of 40%-60%. This ensures that the primer is evenly and delicately applied to the wood surface, significantly improving the coating's uniformity and coverage, and thus enhancing the coating's overall quality. For the drying and curing phase, the innovative solution offers two flexible drying options: room temperature drying and heated drying. The room temperature drying time is set at 2-4 hours, while heated drying maintains a temperature of 40-60 degrees Celsius for 30-60 minutes. Furthermore, the method is compatible with UV curing technology. This diverse drying method can be flexibly adjusted to suit varying production conditions and efficiency requirements, significantly enhancing the adaptability and efficiency of the production process and bringing comprehensive improvements to wood coating application.

[0056]

[0057] According to the above table, Example 4 has the following advantages over other examples:

[0058] 1. Better environmental performance

[0059] The replacement ratio of bio-based materials in Example 4 reached 30%, higher than the 20% in Example 3, 15% in Example 2, and 10% in Example 1. This means that more renewable bio-based materials are used in primer production, reducing dependence on traditional petroleum-based materials, thereby significantly reducing the carbon footprint and being more environmentally friendly.

[0060] 2. Better coating performance

[0061] Higher nanomaterial content: In Example 4, the amount of nanomaterial added was 3% of the total weight of the primer, which was higher than in other examples. More nanomaterial can more effectively enhance the adhesion, abrasion resistance, and weather resistance of the primer.

[0062] Better dispersion: The nanomaterial has the longest dispersion time (60 minutes) and the highest dispersion speed (2500 rpm). This helps ensure that the nanomaterial is evenly dispersed in the primer, thereby maximizing its performance benefits.

[0063] More thorough pretreatment: The bio-based material has a higher pretreatment temperature (60 degrees Celsius) and a longer pretreatment time (3 hours). This helps improve the compatibility of the bio-based material with other primer components, further enhancing the performance of the primer.

[0064] Summary: Example 4, as the optimal example, has achieved the best balance in terms of environmental performance, coating quality and process optimization. In particular, in terms of the replacement ratio of bio-based materials and the addition amount of nanomaterials, Example 4 reached 30% and 3% respectively, which significantly improved the environmental characteristics and coating performance of the primer. In addition, by extending the dispersion time of the nanomaterials and increasing the dispersion speed, the uniform dispersion of the nanomaterials in the primer is ensured, thereby maximizing its performance advantages. At the same time, the optimized pretreatment process further enhances the compatibility of the bio-based materials with other components of the primer. Although Example 4 uses a higher amount of bio-based materials and nanomaterials, which may lead to increased costs, from the perspective of comprehensive performance, environmental benefits and long-term use effects, Example 4 has significant advantages in high performance and sustainability, and is the best choice among all the examples.
