Description

Technical Field

[0001] The invention relates to the technical field of interior decoration material construction, in particular to an integrated process for color matching and painting of indoor water-based paint with low VOC release. Background Art

[0002] In today's interior decoration industry, with rising public awareness of environmental protection and increasingly stringent environmental regulations, low-VOC water-based paint, owing to its environmental advantages, has gradually become the mainstream choice for interior wall coatings. However, current water-based paint color matching and application processes present numerous challenges that need to be addressed, severely hindering its further application. Traditionally, the color matching process for water-based paint relies heavily on manual labor. Colorists rely on their experience to mix different pigments into the water-based paint base, a process that is highly subjective and unstable. On the one hand, manual color matching is extremely inefficient, making it difficult to quickly respond to large-scale projects or diverse color requirements. On the other hand, since manual operation makes it difficult to precisely control the amount of pigment added, color matching results can easily deviate from batch to batch, resulting in inconsistent wall colors and compromising the overall decorative effect. From a construction perspective, the existing color matching and painting processes are independent of each other. After color matching is completed, painting operations must be arranged separately. This not only requires the coordination of different types of workers and the repeated movement of equipment and materials, but also increases construction time and costs. Furthermore, the increase in independent links increases the difficulty of construction management, making poor coordination prone to delays. From an environmental perspective, although water-based paints have significantly reduced VOC emissions compared to traditional oil-based paints, some water-based paints still release a certain amount of volatile organic compounds during the application and subsequent drying process. These VOCs not only cause indoor odors, but can also react with other substances in the air to produce secondary pollution. Long-term exposure to such an environment can cause damage to the occupants' respiratory and nervous systems, especially for sensitive groups such as children and pregnant women. Therefore, the development of an integrated process for indoor water-based paint color matching and application that can balance color matching accuracy, construction efficiency, and ultra-low VOC emissions has become the key to breaking through development bottlenecks in the industry and meeting market demand. Summary of the Invention

[0003] The purpose of the present invention is to provide an integrated process for color matching and painting of indoor water-based paint with low VOC emission. This process will achieve accurate and efficient color matching, breaking through the limitations of traditional manual color matching; simplify the construction process, and abandon the cumbersome mode of separating color matching and painting; at the same time, it will significantly reduce the VOC emission of water-based paint throughout its life cycle, comprehensively improve indoor air quality, effectively protect human health, and provide a green and efficient new solution for the interior decoration industry.

[0020] Specifically, in this embodiment, during the color grading process, the nanometer-level detection precision color sensor of the intelligent color grading device collects the spectral data of the mixed pigment in real time at a frequency of 5-10 times per second, compares it with the target color spectral data, and dynamically adjusts the subsequent pigment addition amount based on the deep learning color grading algorithm until the target color match is achieved within 98%-99.5%.

[0022] Specifically, in this embodiment, the novel coating auxiliary agent is based on the surface active principle and contains a special film-forming promoting component.

[0023] Specifically, in this embodiment, the initial VOC content of the low-VOC water-based paint base is ≤0.02 g / L.

[0024] Specifically, in this embodiment, the hydrophilic group and the pigment-philic group of the novel pigment dispersant function during the high-speed shear stirring process.

[0026] Specifically, in this embodiment, the VOC content in the indoor air after construction is always ≤0.06 mg / m³ after testing.

[0027] Specifically, in this embodiment, a system for an integrated process of color matching and painting of low-VOC indoor water-based paints includes: Intelligent color grading equipment equipped with ultra-precise spectral analysis color sensors and deep learning color grading algorithms trained on massive color data; High-speed shear mixing equipment with a speed range of 1500-2500r / min; An integrated painting device that can automatically adjust the painting pressure between 0.1MPa and 0.5MPa and the painting speed between 3m / min and 8m / min according to the wall or ceiling material; An intelligent ventilation system that can monitor indoor VOC concentration and air humidity in real time and automatically adjust ventilation volume.

[0028] Specifically, in this embodiment, the detection accuracy of the color sensor of the intelligent color adjustment device is at the nanometer level.

[0029] It should be noted that: Construction of the color matching system of the present invention Innovation in Intelligent Color-Torting Equipment: This invention introduces an intelligent color-tuning device equipped with an ultra-precise spectral analysis color sensor with nanometer-level detection accuracy, accurately capturing the spectral information of the target color within milliseconds. The device integrates a deep learning color-tuning algorithm trained on massive amounts of color data. Based on the sensor data, it instantly calculates the precise type and ratio of the required pigment. Compared to traditional manual color-tuning, this device achieves several times higher efficiency and minimizes error rates, ensuring highly consistent color-tuning results across batches, fully meeting the stringent requirements for color richness and accuracy in interior decoration.

[0030] Development of a New Pigment Dispersant: This independently developed new pigment dispersant features a specially designed molecular structure containing numerous hydrophilic and pigment-loving groups. In water-based paint systems, these groups act as "molecular bridges," tightly connecting pigment particles to the water-based paint binder, effectively preventing pigment aggregation. Furthermore, the dispersant itself is synthesized from low-volatile raw materials, effectively eliminating VOC (Vocabulary Oxide) emissions. During the tinting operation, pigment, water-based paint binder, and the new dispersant are mixed in a specific ratio through a high-speed shear mixer. Operating at thousands of revolutions per minute, the equipment utilizes high-intensity mechanical shear forces to evenly and stably disperse the pigment in the water-based paint, producing a tinted paint with consistent color and quality.

[0031] Painting process optimization Integrated painting equipment design: This meticulously designed, integrated painting equipment integrates paint storage, precise delivery, and efficient painting. Equipped with an intelligent pressure and speed control module, it automatically and precisely adjusts the painting pressure and speed based on the specific characteristics of the wall material (such as gypsum board, cement mortar walls, etc.) and pre-set construction requirements. For example, on rough, highly absorbent surfaces, the system automatically increases the painting pressure and decreases the painting speed to ensure sufficient and even paint penetration and adhesion. On smooth surfaces, the system appropriately decreases the pressure and increases the speed to prevent paint accumulation. This intelligent control significantly improves painting quality, eliminating common problems such as missed paint and dripping.

[0032] Application of a new painting additive: Based on the principle of surface activity, this new painting additive significantly reduces the surface tension of water-based paint, making it easier for the paint to spread across the wall and enhancing adhesion. The addition of a special film-forming promoter accelerates the fusion of polymer particles in the water-based paint, promoting rapid drying and formation of the paint film, significantly shortening the application cycle. Before application, the new painting additive is evenly mixed with the water-based paint in a specific ratio. Application using integrated painting equipment ensures high-quality, efficient wall painting.

[0033] Low VOC emission control Low-VOC base and scavenger synergy: A rigorously screened and optimized low-VOC water-based paint base is used, with an initial VOC content far below the industry average. Furthermore, a proprietary VOC scavenger is added to the water-based paint formula. The scavenger molecule contains active functional groups that react chemically with common VOCs (such as formaldehyde and benzene). During the drying process of the water-based paint, the scavenger rapidly reacts with released VOCs, converting them into stable, harmless substances. Tests by authoritative testing agencies have shown that water-based paints using this process reduce VOC emissions by over 80% compared to traditional processes, far exceeding national standards.

[0034] Construction Environment Optimization Measures: During the painting process, an intelligent ventilation system monitors and controls air flow and humidity in real time. The system automatically adjusts ventilation volume based on changes in indoor VOC concentrations, accelerating the evaporation of moisture and residual VOCs in the water-based paint. After construction, professional air quality monitoring equipment is used to regularly monitor indoor air quality to ensure that all indicators continue to meet high standards for indoor environmental quality, creating a safe and comfortable living space for users.

After receiving the sensor data, it instantly calculates the exact amount of red pigment required. , accurate dosage of yellow pigment Here, based on the CIELAB color space theory, a mathematical model of color spectrum data and pigment dosage is established through an algorithm: ,in Indicates the Amount of pigment used, is the characteristic value of spectral data, Corresponding to different pigments, Represents spectral information of different bands. , .

[0037] Put the water-based paint base, the calculated red pigment, yellow pigment and the new pigment dispersant into the high-speed shear stirring equipment.

Under this wall and paint conditions, the experimental determination , , , Calculations show that this pressure and speed setting ensures sufficient and even penetration of the paint. The equipment begins operation, and the paint is evenly applied to the wall at a steady flow rate through the precise delivery system. The equipment operates smoothly throughout the painting process, with no leaks or drips.

[0040] After the paint is finished, the intelligent ventilation system is activated.

During the stirring process, the new pigment dispersant effectively plays a dispersing role, so that the pigment is evenly dispersed in the water-based paint to produce high-quality cyan color paint.

[0045] Painting process 81.5 kg of cyan paint was poured into the storage tank of the integrated painting equipment, and 4 kg of a new painting additive was added. The special film-forming promoting ingredient in this additive accelerates the fusion of polymer particles in the water-based paint, prompting the paint film to dry and form quickly.

After the equipment is started, the paint is applied to the ceiling efficiently and accurately, with an even and smooth coating effect.

[0047] After the application, the intelligent ventilation system continued to operate, providing real-time control of the indoor air environment. After 36 hours, the paint film dried and solidified. Upon inspection, the surface was smooth, firm, and free of any defects.

[0048] VOC emission detection Using professional air quality testing equipment and following a strict testing process, the rooms after construction were tested for VOC emissions. The results showed that the VOC content in the indoor air was 0.03mg / m³, well below the national standard limit, fully demonstrating the excellent effectiveness of the process in reducing VOC emissions. Example 3

[0052] Painting process 99.5kg of purple tinted paint was added to the storage tank of the integrated painting equipment, followed by 6kg of a new painting additive. Based on the principle of surface activity, this additive effectively reduces the surface tension of water-based paint, enhancing the paint's spreadability and adhesion on the wall.

[0053] The wall to be painted is a wooden wall, which is relatively dense and has weak water absorption. According to the fluid mechanics and wall permeability model , , through experimental determination, under the conditions of wooden wall and coating, , , , Based on this, the brushing pressure of the integrated brushing equipment Set to 0.28MPa, brushing speed Adjust to 5m / min. When the equipment is running, the paint is evenly applied to the wall surface at a stable flow rate through the precise delivery system. The painting process is smooth without any missing or dripping.
