Description

Technical Field

[0001] This invention relates to the fields of architectural decoration and cultural relic protection technology, specifically to the preparation of a paint stripping material for corbels and its construction technology. Background Technology

[0002] In the field of construction engineering, the preparation and application techniques of environmentally friendly paint stripping materials are of great significance for the repair and protection of wooden structural components such as corbels and wooden columns. This invention focuses on wooden structural components such as corbels and identifies the following technical shortcomings in the preparation and application techniques of traditional paint stripping materials: 1. Low efficiency of paint stripping: Traditional methods such as scraping and chiseling require manual removal of the paint film, which is not only time-consuming and labor-intensive, but also easily damages the original wood grain and texture of wooden components. Using professional paint strippers can effectively solve the above problems, thoroughly remove all kinds of old paint components, and shorten the average paint stripping time by 50%, significantly improving construction efficiency.

[0003] 2. Poor construction quality: Traditional paint stripping techniques often cause varying degrees of damage to the raw wood. Traditional paint strippers cause multiple groups in the paint film to undergo saponification and dissolve in water, resulting in a decrease in its strength and a weakening of its adhesion to the wood, thereby reducing the durability of the wood by 30%.

[0004] 3. Poor energy conservation and environmental protection: Traditional paint removers cause environmental pollution during use, which is detrimental to the health of construction workers. They are often accompanied by toxic and harmful gases and have disadvantages such as easy volatility and strong corrosiveness. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A technique for preparing a paint remover for corrugated irons, comprising the following specific steps: S1, Mix benzyl alcohol, acetone and hydrogen peroxide thoroughly; S2, after S1 is fully mixed, add methylcellulose and continue stirring until homogeneous; S3, after S2 has been mixed, add distilled water and stir thoroughly until homogeneous; S4. After mixing is completed in S3, the environmentally friendly paint remover can be obtained by letting it stand.

[0006] As a preferred embodiment of the paint stripping material preparation technology for the enamel coating described in this invention, the proportions of benzyl alcohol, acetone, hydrogen peroxide, methylcellulose and distilled water are respectively set as 60-65 parts benzyl alcohol, 25-30 parts acetone, 20-25 parts hydrogen peroxide, 5-10 parts methylcellulose and 10-15 parts distilled water.

[0007] As a preferred embodiment of the paint stripping material preparation technology for the bracket described in this invention, the standing time in step S4 is 5 minutes.

[0008] A technique for applying a paint remover to a bracket, comprising the following specific steps: A1, Experiment: First, five variables were set up: benzyl alcohol, acetone, hydrogen peroxide, methylcellulose, and distilled water, and a three-level experimental design was adopted. The experiment was conducted using an orthogonal experimental method. Then, taking the corrugated board as the research object, the surface paint was removed using environmentally friendly paint remover with different experimental ratios. The appearance, paint removal time, and paint removal effect of the corrugated board before and after paint removal were compared and analyzed. Finally, the optimal environmentally friendly paint remover ratio scheme was determined. A2, Preparation: Based on the optimal formulation of environmentally friendly paint remover, benzyl alcohol, acetone, hydrogen peroxide, methylcellulose, and distilled water are used to prepare an environmentally friendly paint remover. A3, Removal: Remove contaminants from the surface of the corrugated iron; A4, Protection: Covering the area that needs protection with a protective film; A5, Reinforcement: The wooden frame is reinforced with steel wire; A6, Spraying: Based on the prepared environmentally friendly paint stripping material, a dual paint stripping construction method combining manual brushing and mechanical spraying is used to uniformly coat one or more layers of environmentally friendly paint stripping material on the surface of the corrugated board and allow it to stand. A7, Paint Removal: Remove the paint film using a combination of manual cleaning and air compressor blowing.

[0009] As a preferred embodiment of the paint stripping material application technique for a bracket according to the present invention, the settling time in A6 is 15 minutes.

[0010] Compared with existing technologies: 1. High paint stripping efficiency: By optimizing the ratio of environmentally friendly paint stripping materials and adopting a paint stripping technique that combines manual labor with mechanical equipment, the average paint stripping time is reduced by 50%; 2. Excellent construction quality: The construction technology of manual brushing + machine spraying + air compressor blowing can completely remove the original paint of the corrugated board, restore the corrugated board to its original state, and the original wood grain can be clearly observed; 3. High economic and environmental benefits: The environmentally friendly paint remover prepared is not only affordable, but also easy to apply. It is non-toxic and harmless to construction workers and the surrounding environment, and will not cause any pollution. Applying it to the restoration and protection of ancient and modern buildings helps to achieve the dual goals of resource conservation and environmental protection, while also creating considerable economic benefits for society.
